HSK 6 Grammar

Tucked inside a complement, 倒 turns the comment sour — "easy for you to say." It implies the opposite of reality and is aimed mostly at the listener, with 说 / 想.

Structure: Subject + Verb + 得 + 倒 + Adjective

saying it说shuō得deeasy enough倒dào容易róng yìthen，那nàyou你nǐdo it来lái！

Easy for you to say — you do it then!

you你nǐwish想xiǎng得denicely倒dào美měidon't！不bùwork工作gōng zuòyet还háiwant想xiǎngto be paid拿ná工资gōng zī？

You wish! Get paid without working?

Remember: 得 + 倒 = a sarcastic jab — "说得倒容易" = "easy enough for you to say." Reach for it to push back at the other person's 说 / 想. (你想得倒美！= "you wish!")

Watch out

• This 倒 (dào, "but / contrary") rebukes; don't confuse it with 倒 (dǎo, "fall over").

很是 is a dressed-up 很 — the same "very," but with a formal, literary flavour you'll meet in writing rather than everyday speech. The extra 是 makes the emphasis feel weightier.

Structure: Subject + 很是 + Adjective

your你nǐ的deperformance表现biǎo xiànmade让ràngthe boss领导lǐng dǎovery很是hěn shìpleased满意mǎn yì。

Your performance pleased the boss greatly.

doing it this way这样zhè yàng做zuòquite很是hěn shìnecessary必要bì yào。

Doing it this way is quite necessary.

Remember: 很是 = 很 in its Sunday best — a written, weightier "very," pairing with two-syllable adjectives (很是满意, 很是高兴). If it sounds too formal to say out loud, that's exactly the right feel.

Watch out

• Keep it for writing — in speech, plain 很 / 非常 is natural.

足足 stresses that an amount is fully that much — "a full, all of, every bit of." It always pairs with a number, often with 有 or 等.

Structure: 足足 + Verb (+ Number) · Verb + 足足

I我wǒwaited等děng了lefor her她tāa full足足zú zútwo两个liǎng gehours小时xiǎo shí。

I waited a full two hours for her.

he他tāin在zàiChina中国Zhōng guólived住zhù了leall of足足zú zúten years十年shí nián。

He lived in China for all of ten years.

Remember: 足足 = "a FULL, every bit of" (足 = "enough / full") — it always rides a number and underlines that the amount is large: 足足两个小时 ("a whole two hours"), 足足十年 ("all of ten years").

Watch out

• It needs a quantity — 足足 with no number to amplify is incomplete.

一再 means doing something insistently, again and again — "repeatedly, time and again." It precedes a two-syllable verb (often of speech or request), and can take 地.

Structure: Subject + 一再 + Verb

I我wǒagain and again一再yí zài跟gēnyou你nǐtold说shuōout and about，出门chū ménto be要yàocareful小心xiǎo xīn。

I've told you again and again to be careful when you're out.

the teacher老师lǎo shīrepeatedly一再yí zàistressed强调qiáng diàothis这zhèpoint一点yì diǎn。

The teacher stressed this point over and over.

Remember: 一再 = "time and again, insistently" — formal, with two-syllable verbs of speech/thought (一再强调, 一再请求, 一再解释). It's the close cousin of 再三.

Watch out

• Reserve it for repeated deliberate acts — not a plain "often" (that's 常常).

凡是 sweeps over every member of a category — "any, every, whoever / whatever" (= 只要是). It opens the sentence and pairs with 都 / 就 / 一律.

Structure: 凡是 + Noun + 都 / 就 / 一律 + Predicate

all凡是fán shìmembers会员huì yuán都dōuget有yǒua discount折扣zhé kòu。

All members get a discount.

any凡是fán shì不bùdisobedient听话tīng huà的dechild孩子hái zi都dōugets no没méisweets糖táng吃chī。

Any child who misbehaves gets no sweets.

Remember: 凡是 = "any and every, without exception" (= 只要是) — it states a blanket rule and pairs with 都 / 就 / 一律 to nail it down (凡是会员都…). Use it to leave no member out.

Watch out

• It needs the 都 / 就 / 一律 downstream to complete the "every" sweep.

向来 describes a long-standing habit or trait — "always, has always, all along." It's very close to 一向.

Structure: Subject + 向来(都) + Verb / Adjective

he他tāhas always向来xiàng lái都dōuvery很hěnpunctual守时shǒu shí。

He's always been punctual.

I我wǒhave never向来xiàng lái不bùliked喜欢xǐ huanordering点diǎntakeaway外卖wài mài。

I've never liked ordering takeaway.

Remember: 向来 = a settled, unchanging pattern over time ("has always been this way") — interchangeable with 一向 (further down this file). It looks back over the long run.

Watch out

• It's for long-held traits — not a one-off recent stretch (that's 一直).

果然 confirms a prediction came true — "sure enough, just as expected." It's the opposite of 竟然 / 居然 ("unexpectedly").

Structure: Subject + 果然 + Predicate · 果然如此 / 果然不出所料

first place第一名dì yī míngsure enough果然guǒ ránis是shìher她tāI！我wǒ就jiùknew it知道zhī dào。

First place is her, sure enough — I knew it!

the forecast天气预报tiān qì yù bàosaid说shuōrain下雨xià yǔand so it did，果然如此guǒ rán rú cǐ。

The forecast said rain, and sure enough it did.

Remember: 果然 = "sure enough, just as I foresaw" — it confirms a prediction (果然如此, "just so"). It's the mirror image of 竟然 / 居然 ("and yet, unexpectedly"): foreseen vs surprising.

Watch out

• If the outcome surprised you, you want 竟然 / 居然, not 果然.

似乎 hedges toward an impression — "it seems, apparently, as if." It's a formal cousin of 好像, used for an uncertain judgement, or to flag "seems X but actually Y."

Structure: Subject + 似乎 ……

the boss老板lǎo bǎntoday今天jīn tiānseems似乎sì hūnot very不太bú tàihappy高兴gāo xìng。

The boss seems a little upset today.

she她tāseems to be似乎sì hūhiding隐瞒yǐn mán了lesomething什么shén me。

She seems to be hiding something.

Remember: 似乎 = the formal 好像 ("it seems, as if") — a hedged, uncertain impression. It can quietly set up "似乎…其实…" ("seems so, but actually…").

Watch out

• It's writing-leaning — in casual speech 好像 is the natural choice.

偏偏 marks a frustrating clash with what was required or hoped — "of all things, just had to." It can also mean "only … (annoyingly)," singling out the one exception.

Structure: A ，Subject + 偏偏 + B

we told him not to不bù叫jiào他tāgo去qùhe，他tāof all things偏偏piān piāninsisted on要yàogoing去qù。

We told him not to go, and of course he insisted.

everyone else别人bié rén都dōuearly早zǎoarrived到dào了leonly，偏偏piān piānhe他tāalone一个人yí ge rénwas late迟到chí dào。

Everyone else was early — only he was late.

Remember: 偏偏 = a frustrated "of all things / just HAD to" — things go against what you wanted (叫他别去，他偏偏要去, "told him not to, and of course he insisted"). It can also single out the one annoying exception ("only he…").

Watch out

• It always carries annoyance — things deliberately not going your way.

Here 再不 … 也 … concedes an extreme — "however un-… one is, still …." It grants the unfavourable case and overrides it (≈ 即使不…也…).

Structure: 再不 + Adjective ，也 + Result

however un-再不zài bùfond喜欢xǐ huanyou，你nǐstill也yěhave to得děigo去qùonce一趟yí tàng。

However little you like it, you still have to go.

even if not再不zài bùhungry饿èstill，也yěeat吃chīa little点diǎn吧ba。

Even if you're not hungry, eat a bit.

Remember: 再不 X 也 Y = "however un-X, still Y" — it grants even the unfavourable extreme and holds the result firm (再不喜欢也得去, "however little you like it, you still have to go"). ≈ 即使不…也….

Watch out

• This 再不 ("however not…") differs from the warning 再不…就…了 ("if not now, then…!") in HSK 5.

一律 means a rule applies to all alike — "uniformly, across the board, without exception." It's written / official, often pairs with 都, and is mostly for people.

Structure: 一律 (+ 都) + Verb / Adjective

tomorrow's明天míng tiān的demeeting会议huì yìwithout exception一律yí lǜ都dōumust要yàoattend参加cān jiā。

Everyone must attend tomorrow's meeting.

over-seventies七十岁qī shí suì以上yǐ shàngriding坐zuòthe bus公交gōng jiāoall一律yí lǜfree免费miǎn fèi。

Over-70s ride the bus free, no exceptions.

Remember: 一律 = "one treatment for ALL, across the board" — official/written, often with 都 (一律免费, "free for everyone, no exceptions"). Picture a single rule stamped on every case alike.

Watch out

• It's for uniform treatment, mostly of people — heavier and more official than a plain 都.

无非 plays a matter down to its essentials — "nothing more than, merely, only." It often ends with 罢了 or 而已. The 是 is optional with a verb, but required with a noun.

Structure: 无非 + (是) + Verb / Noun (+ 罢了 / 而已)

I我wǒonly无非wú fēitold off批评pī píng了lehim他tāa bit几句jǐ jùhe，他tāwhy怎么zěn mecrying哭kū了le？

I only told him off a little — why's he crying?

the child孩子hái ziwants想xiǎng得到dé dào的deis nothing but无非wú fēi是shìyour你nǐ的deattention关心guān xīn罢了bà le。

All the child wants is your attention, nothing more.

Remember: 无非 = "nothing more than, merely" — it strips a thing to its plain core, often capped with 罢了 / 而已 ("…that's all"). The 是 is optional before a verb, but required before a noun (无非是个误会).

Watch out

• It deflates ("it's only…") — don't use it where you mean to emphasise.

一向 marks a consistent, long-held habit or attitude — "always, all along." The feeling is "it's always been this way."

Structure: Subject + 一向 + Habit / Attitude

Xiao Wang小王Xiǎo Wánghas always一向yí xiàngcome to work上班shàng bānvery很hěnearly早zǎothis time，这次zhè cìwhat's怎么zěn mewrong了le？

Xiao Wang's always early to work — what happened this time?

mum妈妈mā mahas always一向yí xiàngbacked支持zhī chímy我wǒ的dedecisions决定jué dìng。

Mum has always backed my decisions.

Remember: 一向 = "it's always been this way" — a settled disposition over the long run. It's the twin of 向来 (earlier in this file); both look back over a long, unbroken habit.

Watch out

• For one recent unbroken stretch ("the whole time lately"), use 一直, not 一向.

到时候 points to a future moment when something will apply — "when the time comes, by then."

Structure: …… ，到时候 + ……

now现在xiàn zàiif you don't不bùproperly好好hǎo hǎoprepare准备zhǔn bèiwhen the time comes，到时候dào shí housurely肯定kěn dìngdo badly考不好kǎo bu hǎo。

If you don't prepare now, you'll do badly when the time comes.

you你nǐfirst先xiānyourself自己zì jǐtry试试shì shithen，到时候dào shí houI我wǒ再zàiteach教jiāoyou你nǐ。

Try it yourself first; I'll teach you when the time comes.

Remember: 到时候 = "when the time comes, by then" — it points ahead to a future moment. Handy set phrases: 到时候见 ("see you then"), 到时候看吧 ("we'll see then").

Watch out

• It looks forward — don't use it for "at that (past) time," which is 那时候.

何必 is a rhetorical "why (must) …?" — arguing that something is unnecessary. It often ends with 呢, and 何必呢？ can stand alone for "why bother?"

Structure: Subject + 何必 + Predicate (+ 呢)

he他tāalready已经yǐ jīngapologised道歉dào qiàn了leyou，你nǐwhy何必hé bìstill还háibe angry生气shēng qì？

He's already apologised — why stay angry?

we're all都是dōu shìfamily一家人yì jiā rénwhy bother，何必hé bìbeing so这么zhè meformal客气kè qi？

We're all family — no need to be so formal.

Remember: 何必 = a rhetorical "why (must) you…?" = "there's no need." It nudges someone to drop a pointless effort (你何必生气？ "why be angry?"); 何必呢？ alone = "why bother?". Proverb: 早知如此，何必当初 ("if you'd known, why do it in the first place?").

Watch out

• It's not a real question — it's arguing that the thing is unnecessary.

来着 tags onto a sentence to recall what was happening or said a moment ago — "(someone) was just …, what was it again?" It's casual and spoken. It has no negative form (never 不 / 没来着), and in a question it appears only with 什么, 谁, or 哪儿.

Structure: Sentence + 来着

yesterday昨天zuó tiānsomeone有yǒu人réncame来láilooking for找zhǎoyou你nǐ来着lái zhe。

Someone came looking for you yesterday.

you你nǐjust now刚才gāng cáiwere saying说shuōwhat什么shén me来着lái zhe？

What were you just saying again?

Remember: 来着 = "…what was it again?" — a casual tag for recalling the just-past (你刚才说什么来着？). Two limits: no negative (never 没来着), and in questions only with 什么 / 谁 / 哪儿.

Watch out

• It's purely for the recent past — not the distant past, and not future.

以免 introduces an unwanted outcome to prevent — "so as to avoid, in order not to, lest." (It's a shortened 以便避免.) The first clause gives a warning; the 以免 clause names the bad result. It needs a complete verb phrase, not a bare word.

Structure: Action ，以免 + Undesirable Result

there are这儿zhèr有yǒuhigh-voltage wires here高压电线gāo yā diàn xiànplease，请qǐngdon't不要bú yàogo near靠近kào jìnlest，以免yǐ miǎnsomething发生fā shēngdangerous happen危险wēi xiǎn。

There are high-voltage wires — please keep away, lest something dangerous happen.

you你nǐhurry up and赶紧gǎn jǐngo走zǒuso as not to，以免yǐ miǎnbe late晚wǎn了le。

Hurry up and go, so you're not late.

Remember: 以免 = 以 ("so as to") + 免 ("avoid") = "lest / so as to avoid." The 以免 clause names the bad thing you're heading off (小心点，以免出事). It needs a full verb phrase: 以免晚了 ✓, not 以免晚.

Watch out

• It always introduces the unwanted outcome — for a wanted purpose, use 以便 ("so as to").

以及 links nouns or phrases (chiefly in writing), often appending less-central items at the end — "as well as, along with, and." The part before 以及 is usually the main one. It can also join clauses. It's more formal than 和.

Structure: A、B 以及 C

hearing听觉tīng juésight、视觉shì juéas well as以及yǐ jítouch触觉chù juéare all都dōu属于shǔ yúsenses感官gǎn guān。

Hearing, sight, as well as touch are all senses.

the yard院子里yuàn zi lǐhas growing种着zhòng zheroses玫瑰méi guijasmine、茉莉mò liand以及yǐ jíother其他qí tāplants花草huā cǎo。

The yard has roses, jasmine, and other plants.

Remember: 以及 = a formal "and / as well as," with the MAIN items before it and secondary ones after (玫瑰、茉莉 以及 其他花草). More formal than 和, and it can also join clauses.

Watch out

• Put the central items before 以及 — what follows reads as an add-on.

总之 sums up what came before — "in short, in a word, all in all." It introduces a wrapping-up conclusion.

Structure: （……，）总之 ，……

he他tāoften经常jīng chánglate迟到chí dàowith work，工作gōng zuòalso也yěnot不bùresponsible负责fù zéin short，总之zǒng zhīthe firm，公司gōng sīmust必须bì xūlet go of解雇jiě gùhim他tā。

He's often late and not responsible — in short, the firm has to let him go.

whatever不管bù guǎnreason理由lǐ yóu是shì什么shén mein short，总之zǒng zhīI我wǒwon't不会bú huìagain再zàitrust相信xiāng xìnhim他tā了le。

Whatever his reasons, in short I won't trust him again.

Remember: 总之 = 总 ("sum up") + 之 = "in a word, to sum up." It gathers the scattered points into one bottom line — the verbal "long story short."

Watch out

• It needs preceding points to gather — it caps an argument, it doesn't open one.

则 marks a contrast between two clauses — "whereas, while" (the same idea as 却). It's formal and written, sits at the head of the second clause's predicate, and often appears with 而.

Structure: Clause 1 ，(而) + Subject + 则 + Predicate

southerners南方人nán fāng rénlike喜欢xǐ huaneating吃chīsweet甜tián的denortherners，北方人běi fāng rénwhereas则zélike喜欢xǐ huaneating吃chīsalty咸xián的de。

Southerners like sweet food, whereas northerners like salty.

my我wǒwife老婆lǎo pois used to习惯xí guàncountry乡村xiāng cūnlife生活shēng huóI，我wǒwhereas则zéam used to习惯xí guàncity城市chéng shìlife生活shēng huó。

My wife is used to country life, whereas I'm used to the city.

Remember: 则 = formal "whereas" — it heads the second clause's predicate (北方人则…) to set two cases side by side. It often pairs with 而 (而…则…). Same contrast as 却, dressier register.

Watch out

• It sits after the second subject, before the verb — 北方人则喜欢…, not 则北方人….

In formal written Chinese, 本 means "this (very) / one's own" — always the speaker's own side. It pairs with single-syllable nouns (人, 校, 市, 国, 周, 月, 年, 次) and a few two-syllable ones (公司, 组织). 本人 = "I, myself" (common on résumés).

Structure: 本 + Noun

customer-first顾客至上gù kè zhì shàngis是shìour本běncompany's公司gōng sī的deethos理念lǐ niàn。

"Customer first" is our company's ethos.

this本běnschool校xiàodoesn't不bùallow允许yǔn xǔoutside外校wài xiàostudents学生xué shēngto freely随便suí biàncome and go进出jìn chū。

This school doesn't allow outside students to come and go freely.

Remember: 本 = "this very / our own (side)" — the voice of notices and officialese: 本公司 ("our company"), 本校 ("this school"), 本人 ("I, myself"). It always speaks from the in-group.

Watch out

• It's self-referential and formal — for a plain "this," use 这.

The suffix 性 turns a word into an abstract quality — "-ness, -ity, -ability" (also "-ic"). Like 化, it's a productive suffix: 可能性, 重要性, 科学性, 可行性.

Structure: Word + 性

this这个zhè geplan方案fāng ànhas no没有méi yǒufeasibility可行性kě xíng xìng。

This plan isn't feasible.

your你nǐ的dework作品zuò pǐnmore and more越来越yuè lái yuèhas有yǒucreativity创造性chuàng zào xìng。

Your work is more and more creative.

Remember: 性 = "-ness / -ity" — turns a word into an abstract quality: 可能性 (possibility), 重要性 (importance), 可行性 (feasibility), 创造性 (creativity). It's the noun-making sibling of the verb-making 化.

Watch out

• It builds a noun of quality — pair it with 有 / 没有 (有可行性), not used like an adjective.

是否 is a formal, written 是不是 — "whether (or not)." It forms or embeds a yes-no question, before a verb or adjective.

Structure: 是否 + Verb / Adjective

please请qǐngconfirm确认què rènthe details信息xìn xīwhether是否shì fǒucorrect正确zhèng què。

Please confirm whether the details are correct.

your你nǐparents父母fù mǔwhether是否shì fǒuagree to同意tóng yìyou你们nǐ menliving住zhùtogether在一起zài yì qǐ？

Do your parents agree to you living together?

Remember: 是否 = the written 是不是 ("whether"). Same job, formal register — natural in a form or report, stiff in chat (where you'd say 是不是).

Watch out

• It sits before the verb/adjective: 是否正确, not 正确是否 (that "…or not" tail is 与否, below).

与否 is a classical particle for "… or not" — it nominalises a yes-no question into an abstract phrase, sitting at the end of a clause. It's highly formal.

Structure: Verb / Adjective + 与否

success成功chéng gōngor not与否yǔ fǒu，要yàois down to靠kàoyourself自己zì jǐ。

Whether or not you succeed is down to you.

this这zhè件jiànmatter事shìimportant重要zhòng yàoor not与否yǔ fǒudepends on，取决于qǔ jué yúhow you你nǐ怎么zěn mesee it看kàn。

Whether this matters depends on how you see it.

Remember: 与否 = "… or not," tacked on the END to make a topic — 成功与否 ("the matter of whether you succeed"). It turns a yes-no question into a noun-like phrase. Highly formal; 是否 leads, 与否 trails.

Watch out

• It comes after the verb/adjective (成功与否) — the front-position version is 是否.

之 is the classical / written equivalent of possessive 的, found in set phrases, titles, and formal documents. It can't replace every 的 — it's fixed to certain pairings.

Structure: Noun + 之 + Noun

to harm others害人hài rén之zhīa mind心xīnone must not have不可有bù kě yǒu。

Never mean harm to others.

these这些zhè xiēmethods方式fāng shìstill仍rénghave有yǒushort-不足bù zú之zhīcomings处chù。

These methods still have shortcomings.

Remember: 之 = the literary 的 — but fixed to set expressions, not a free swap: 三分之一 (a third), 意料之中 (as expected), 不足之处 (shortcomings). Learn the phrases whole.

Watch out

• You can't sprinkle 之 in for any 的 — 我之书 is wrong; it's 我的书.

The particle 嘛 marks something as self-evident from the speaker's point of view — "obviously, of course." (Same sound as the yes-no 吗, but a different job.)

Structure: Statement + 嘛

if you don't不bùwant to想xiǎnggo去qùthen就jiùdon't不要bú yàogo去qù嘛ma。

If you don't want to go, then don't — obviously.

he他tāpretty挺tǐngwell-off有钱yǒu qián的de嘛ma。

He's clearly pretty well-off.

Remember: 嘛 = "obviously, of course" — frames the point as self-evident (不想去就不要去嘛, "then just don't go, obviously"). Same sound as the question 吗, opposite job: 嘛 asserts, 吗 asks.

Watch out

• Don't mishear it as 吗 — 嘛 makes a (slightly impatient) statement, not a question.

The casual particle 呗 signals that something is obvious or simply how it is — "well, obviously; then just …; so be it." It can also carry resignation or a lack of enthusiasm.

Structure: Sentence + 呗

if you can't不会bú huìthen就jiùjust好好hǎo hǎolearn it学xué呗bei。

If you can't, then just learn it — simple.

if you don't不bùwant to想xiǎnggo去qùthen就jiùdon't不bùgo去qù呗bei。

If you don't want to go, then don't, then.

Remember: 呗 = a shrug: "well, obviously / then just… / so be it." Very colloquial, often a touch resigned (不会就学呗, "if you can't, then just learn it — what else"). It waves the matter away as plain.

Watch out

• It's very casual and can sound dismissive — read the resignation in its tone.

鉴于 introduces a consideration that grounds a decision — "in light of, in view of, seeing that." It's formal and official, and opens the sentence.

Structure: 鉴于 + Observation ，Conclusion / Suggestion

in view of鉴于jiàn yúit's是shìan emergency紧急jǐn jí情况qíng kuàngwe，我们wǒ menshould应该yīng gāias soon as possible尽快jǐn kuàimake做出zuò chūa decision决定jué dìng。

Given it's an emergency, we should decide as soon as possible.

in view of鉴于jiàn yúlast week's上周shàng zhōu的deincident事件shì jiànthe government，政府zhèng fǔtightened加强jiā qiáng了lesecurity安保ān bǎo。

In view of last week's incident, the government tightened security.

Remember: 鉴于 = "in light of, given that…" (鉴 = "examine / consider") — it cites the basis for the decision that follows. Formal, official, sentence-opening: 鉴于…，(因此) we should…. It's the weightier cousin of 由于.

Watch out

• It grounds a decision/conclusion on a consideration — heavier and more official than a plain 因为.

岂不是 asks a rhetorical question expecting agreement — "wouldn't that be …?, isn't that …?" The speaker already knows the answer.

Structure: 岂不是 + Rhetorical Question

they他们tā mendon't不bùcome来láiwouldn't that be岂不是qǐ bú shìeven更gèngbetter好hǎo？

Wouldn't it be even better if they didn't come?

you你nǐdoing it这样zhè yàngthis way做zuòaren't you just岂不是qǐ bú shìmaking给gěiyourself自己zì jǐ找zhǎotrouble麻烦má fan？

Aren't you just making trouble for yourself?

Remember: 岂不是 = a literary "wouldn't that be…?!" (岂 = "how could it not") — the answer is taken for granted, so it argues a point rather than asks (他们不来岂不是更好？ = "surely that'd be better").

Watch out

• It's rhetorical — don't expect (or give) a literal yes/no.

非(要) … 不可 marks strong determination — "simply must, insist on." The 不可 can drop when the speaker dislikes the action (他非要喝). The frame 非 + … + 不可 also means "is bound to (happen)."

Structure: Subject + 非(要) + Verb Phrase + 不可

this这个zhè geproject项目xiàng mùsimply has to非fēihim他tā来láibe done by做zuò不可bù kě。

This project simply has to be done by him.

today今天jīn tiānso那么nà mecold冷lěngmy，我wǒdaughter女儿nǚ érinsists on非要fēi yàowearing穿chuāna skirt裙子qún zi。

It's so cold, yet my daughter insists on wearing a skirt.

Remember: 非 … 不可 = a double-negative lock: "must / insist on." 非 ("not unless") + 不可 ("can't not") clamp shut on "simply have to." The 不可 can drop when you disapprove (非要穿). It also means "bound to": 再不走非迟到不可.

Watch out

• Don't read 非 as plain "not" here — 非…不可 is a positive "must," via two negatives.

兼 means holding two roles or jobs at once — "and also, doubling as, concurrently." It can come before or after the verb.

Structure: Subject + 兼 + Role / Verb + A 和 B · 是 + N1 + 兼 + N2

he他tāis是shìthis这zhè首shǒusong's歌gē的delead singer主唱zhǔ chàngand also兼jiān词cílyricist作者zuò zhě。

He's both the lead singer and the lyricist of this song.

in在zàithat那nà部bùfilm电影diàn yǐng里lǐhe，他tāwas both兼jiān做zuòdirector导演dǎo yǎnand和hélead actor男主角nán zhǔ jué。

In that film he was both director and lead actor.

Remember: 兼 = "doubling as, both … and …" — one person, two hats at once: 主唱兼词作者 ("lead singer and lyricist"). It compactly joins two simultaneous capacities.

Watch out

• It joins roles/jobs, not random nouns — for plain "and" between things, use 和.

莫非 voices a dawning suspicion as a guess or rhetorical question — "could it be that …?, don't tell me …." It's like 难道, usually opens the second clause, and 不成 is optional.

Structure: Fact ，莫非 + conjecture (+ 不成)？ · 莫非 + rhetorical question

so这么zhè melate晚wǎnhe他tāstill还háihasn't没méicome back回来huí láicould it be，莫非mò fēisomething出chū了le什么shén mehappened事shì？

So late and he's not back — could something have happened?

don't tell me莫非mò fēiyou你nǐreally真的zhēn debelieve相信xiāng xìnhim他tā？

Don't tell me you actually believe him?

Remember: 莫非 = a worried "could it be…? / don't tell me…" — a suspicion dawning on the speaker (≈ 难道). The 不成 tail is optional. Picture the penny starting to drop with unease.

Watch out

• It floats a guess, not a fact — the answer is feared/suspected, not known.

由此 draws a consequence from a reason or situation — "from this, hence, thereby." It usually pairs with 可见 / 看来 / 说来.

Structure: Reasons ，由此 + Result / Implication

from this由此yóu cǐit's clear可见kě jiànreform，改革gǎi géis是shìhow多么duō menecessary必要bì yào。

From this we can see how necessary reform is.

people人们rén menoveruse滥用làn yòngpesticides农药nóng yàoand from this，由此yóu cǐcame产生chǎn shēng了lefood-食品shí pǐnsafety安全ān quánproblems问题wèn tí。

People overuse pesticides, and food-safety problems have come from this.

Remember: 由此 = "from this (it follows)…" (由 "from" + 此 "this") — and the set wrap-ups 由此可见 / 看来 / 说来 = "from this we can see / it would seem…". A formal "therefore, from the above."

Watch out

• It points back to what was just said as the basis — it can't open with no prior reason.

莫过于 (literally "none surpasses") singles out the utmost case — "nothing is more … than B." It's literary and emphatic.

Structure: Topic / Question + 莫过于 + Answer

in life人生rén shēngthe saddest最zuì悲伤bēi shāng的dething事shìis nothing more than莫过于mò guò yúlosing失去shī qùyou你nǐlove爱ài的desomeone人rén。

Nothing in life is sadder than losing someone you love.

here这里zhè lǐthe best最zuì好hǎo的deuniversity大学dà xuéis none other than莫过于mò guò yúPeking University北大Běi Dà。

The best university here is none other than Peking University.

Remember: 莫过于 = "none surpasses" = "nothing is more … than B." It crowns B the supreme example, usually after a 最 phrase (最…的莫过于…). Literary and emphatic.

Watch out

• B is the peak case — don't follow 莫过于 with a middling example.

与其 A，不如 B weighs two options and picks B — "rather than A, better to B." You can add 还 / 倒 / 真 before 不如. The variant 与其说 A，不如说 B means "more B than A."

Structure: 与其 + A ，(还)不如 + B · 与其说 A ，不如说 B

rather than与其yǔ qíat在zàihome家jiāwatch看kànTV电视diàn shìbetter to，不如bù rúgo out出去chū qùfor a walk走走zǒu zou。

Rather than watch TV at home, better to go out for a walk.

more than与其说yǔ qí shuōhe他tāis是shìmy我wǒteacher老师lǎo shīrather，不如说bù rú shuōhe他tāis是shìmy我wǒfriend朋友péng you。

He's more a friend than a teacher.

Remember: 与其 A 不如 B = "rather than A, better B" — it rejects A, picks B. The 与其 sets up the option you drop, 不如 the one you take. Variant 与其说 A 不如说 B = "more B than A" (recasting a description).

Watch out

• Order is fixed: 与其 + the rejected option first, 不如 + the chosen one second.

跟 … 似的 draws a vivid comparison — "just like, as if (it were) …" (the same as 像…一样). It's common in descriptive writing. The 似 can be read shì or sì.

Structure: 跟 + Noun / Pronoun / Adjective + 似的

the two of them她们tā men俩liǎare as close好hǎo得deas跟gēnreal sisters亲姐妹qīn jiě mèi似的shì de。

The two of them are as close as real sisters.

lately最近zuì jìnthe weather天气tiān qìis as hot热rè得deas跟gēna steamer蒸笼zhēng lóng里lǐ似的shì de。

It's been as hot as a steamer lately.

Remember: 跟 … 似的 = 像 … 一样 ("just like, as if") — a vivid simile (热得跟蒸笼似的, "hot as a steamer"). 似的 caps the comparison; 似 reads shì or sì.

Watch out

• It's a simile frame — pair it with a vivid image, not a literal fact.

不愧是 (or 不愧为) praises someone as fully deserving a title — "truly is a …, lives up to the name of." It carries praise, so you use it of others, not yourself.

Structure: Subject + 不愧是 / 不愧为 + reputation

he他tātruly is不愧是bú kuì shìan一名yì míngexcellent优秀yōu xiù的deteacher老师lǎo shī。

He truly is an excellent teacher.

her她tā的deacting表演biǎo yǎnso太tàisuperb棒bàng了leno wonder she's，不愧是bú kuì shìwon拿过ná guoan Oscar奥斯卡Ào sī kǎ的de。

Her acting was superb — no wonder she's an Oscar winner.

Remember: 不愧是 = "nothing to be ashamed of = truly lives up to it" (愧 = "ashamed"). It praises — "no wonder he's a top teacher." Reserve it for others, never yourself. 是 swaps freely for 为.

Watch out

• It's a compliment — saying 我不愧是… of yourself sounds boastful and odd.

由 … 做主 assigns decision-making authority — "(it's) for … to decide, … is in charge."

Structure: Area of responsibility + 由 + Person + 做主

our我们wǒ menhousehold家jiā由yóumy我wǒmum妈妈mā maruns做主zuò zhǔshe，她tāsays说shuōwhatever什么shén mewe我们wǒ menjust就jiùdo做zuò什么shén me。

In our house, my mum's the boss — whatever she says, we do.

Everything's your call — and you're responsible if anything goes wrong.

Remember: 由 X 做主 = "it's X's call, X is the boss" — 由 (assigns the doer) + 做主 ("be master of it"). 家里由我妈做主 ("at home, mum's in charge"). It hands the decision firmly to X.

Watch out

• It assigns authority, not just action — the named person decides, not merely does.

非得 … 不可 / 不行 / 不成 is an emphatic necessity — "(one) simply has to, must." It's the fuller form of 非…不可, with 得 stressing the obligation.

Structure: Statement ，非(得) + Action + 不可 / 不行 / 不成

now现在xiàn zàiit's是shìan emergency紧急jǐn jí情况qíng kuàngsimply must，非得fēi děiat once马上mǎ shàng动dòngoperate手术shǒu shù不可bù kě。

It's an emergency — we simply have to operate at once.

if you have有yǒusomething to say话huàjust say it好好hǎo hǎo说shuōwhy，干嘛gàn mámust you非得fēi děiargue吵架chǎo jià？

Talk it out properly — why must you argue?

Remember: 非得 … 不可 = "simply HAVE to" — the fuller, more insistent 非…不可, with 得 (děi, "must") driving the obligation home (非得马上手术不可). It leaves no alternative.

Watch out

• The closing 不可 / 不行 / 不成 are interchangeable — keep one of them to seal the "no choice" frame.

一来 … 二来 … lists two (or more) reasons or aims — "for one thing …, for another …." The 是 and 也 are optional.

Structure: 一来 + Reason 1 ，二来 + Reason 2

this time这次zhè cìcoming to来láiChina中国Zhōng guófor one thing，一来yì lái是shìto improve提高tí gāomy Chinese中文Zhōng wénfor another，二来èr lái是shìto understand了解liǎo jiěChinese中国Zhōng guóculture文化wén huà。

I came to China to improve my Chinese, and to understand its culture.

Don't go there — for one thing the hotels are pricey, for another there's no scenery.

Remember: 一来…二来… = "for one thing…, for another…" — a tidy way to count off reasons or aims (一来…，二来…，三来…). The 是 / 也 are optional padding.

Watch out

• It enumerates reasons/purposes, not a time sequence — that's 先…然后….

In spoken Chinese, 谅 voices a confident, slightly challenging bet — "I bet …, I'm sure …, you wouldn't dare." The speaker is daring the other person, so it almost always comes with 不 / 没 plus 也, and the speaker is usually 我.

Structure: 谅 + Subject + 也 + 不 / 没 + Verb Phrase

I bet谅liànghe他tā也yěwouldn't dare不敢bù gǎn！

I bet he wouldn't dare!

I我wǒbet谅liàngyou你nǐ也yěwouldn't dare不敢bù gǎngo and去qùcomplain投诉tóu sù。

I bet you wouldn't dare go and complain.

Remember: 谅 = a daring "I bet you wouldn't…" — a confident challenge, leaning on 也 + 不 / 没 (谅他也不敢, "bet he wouldn't dare"). The speaker is usually 我, sizing up the other person.

Watch out

• It's spoken and a touch confrontational — it almost always carries the 不/没 + 也, not a plain positive.

不屑 means thinking an action is beneath one's dignity — "disdain to, won't lower oneself to, can't be bothered with." There's clear contempt in it: the subject looks down on doing the thing. You can say 不屑 or, more literary, 不屑于.

Structure: Subject + 不屑(于) + Verb / Verb Phrase

he他tāis是shìa个gèhonest诚实chéng shí的deman人rénwon't stoop to，不屑bú xièlying说谎shuō huǎng。

He's an honest man — he won't stoop to lying.

he他tāis above不屑于bú xiè yúsaying说shuōother people's别人bié rén的debad things坏话huài huà。

He's above bad-mouthing other people.

Remember: 不屑 = "it's beneath me" — disdain to do it (屑 = "worth bothering with," so 不屑 = "not worth my while"). 不屑说谎 = "won't stoop to lying." 不屑于 is the more literary variant.

Watch out

• It carries contempt — the subject feels the action is below them, not merely declines it.

以便 is a formal "in order to, so as to (make it easier to)." It links an action to the desired outcome that action makes possible, and often takes a following 能.

Structure: Action ，以便 (+ 能) + Outcome

we我们wǒ menvery很hěnearly早zǎo就jiùwent to去qù了lethe airport机场jī chǎngso that，以便yǐ biànwe could能néngcatch赶上gǎn shàngthe最zuìearliest早zǎo的deflight飞机fēi jī。

We went to the airport very early so we could catch the earliest flight.

please请qǐngleave留下liú xiàyour number电话diàn huàso that，以便yǐ biànwe我们wǒ mencan contact联系lián xìyou您nín。

Please leave your number so we can contact you.

Remember: 以便 = "so as to (make it easier to)" — names a WANTED outcome the action enables (早点去，以便能赶上). Its mirror is 以免 ("so as to avoid" a bad one): 以便 chases the good, 以免 dodges the bad.

Watch out

• Formal/written — in speech use 为了 or the mid-clause 好.

假使 is a formal, written word for "if, supposing, in the event that." It opens a hypothetical condition, and the result clause usually carries 就 (or 便). It's a close sibling of 如果 / 假如 / 倘若 — the difference is register, not meaning.

Structure: 假使 + Condition ，(就 / 便) + Result

if假使jiǎ shǐthere were no没有méi yǒuwater水shuǐlife，生命shēng mìngthen就jiùcouldn't无法wú fǎexist存在cún zài。

If there were no water, life couldn't exist.

if假使jiǎ shǐyou你nǐwere是shìme我wǒyou，你nǐwould会huìhow怎么zěn medo it做zuò？

If you were me, what would you do?

Remember: 假使 = a formal/written "if, supposing" (假 = "suppose") — same meaning as 如果 / 假如 / 倘若, just dressier; the result takes 就 / 便. Climb the register ladder: 要是 (casual) → 如果 → 假如 → 假使 / 倘若 (literary).

Watch out

• In everyday speech it sounds bookish — use 如果 / 要是.

因(为) … 而 … is a formal cause-and-effect frame: 因为 states the cause, and 而 introduces the resulting action or state — "because of X, (one) therefore Y." In this written style 因为 often shortens to just 因, giving a tighter sentence.

Structure: Subject + 因(为) + Cause + 而 + Result

I我wǒbecause因为yīn wèigot ill生病shēng bìngso而értook leave请假qǐng jià。

Because I got ill, I took time off.

Europe's欧洲Ōu zhōu的deeconomy经济jīng jìbecause of因为yīn wèithe debt债务zhài wùcrisis危机wēi jī而érfell into陷入xiàn rùrecession衰退shuāi tuì。

Europe's economy fell into recession because of the debt crisis.

Remember: 因(为) … 而 … — 而 is the hinge swinging from cause to effect ("because X, thereby Y"). In careful writing, 因为 contracts to a tight 因 (因病请假, "took leave due to illness").

Watch out

• Keep the 而 — it's what links the effect to the cause in this frame.

借 … 之名 means doing one thing under the cover of another — "in the name of, under the pretext of, using … as an excuse." It usually hints that the stated name is just a front for a hidden motive.

Structure: Subject + 借 + Noun + 之名 + Situation

some有些yǒu xiēpeople人rénin借jiècharity's慈善cí shànname之名zhī míngswindle money骗钱piàn qián。

Some people swindle money in the name of charity.

he他tāunder the pretext借jièof a meeting开会kāi huì之名zhī míngwent，去qùtravelling旅游lǚ yóu。

Under the pretext of a meeting, he went off travelling.

Remember: 借 X 之名 = "borrowing X's name as a cover" (借 = "borrow") — it hints the name is a front masking the real aim (借慈善之名骗钱). Contrast the neutral 以…的名义 ("in the name of," below).

Watch out

• It implies a pretext — for a neutral "in the name of," use 以…的名义.

通过 … ，使 … is a formal cause-and-effect pair: 通过 names the means (an action or process), and 使 names the effect it brings about — "by means of …, it makes / causes …."

Structure: 通过 + Verb (situation) ，使 + Result

through通过tōng guòexercise锻炼duàn liànthe，使shǐbody身体shēn tǐbecomes更gènghealthier健康jiàn kāng。

Through exercise, the body is made healthier.

through通过tōng guòthis这zhè件jiànmatter事shìit made，使shǐme我wǒunderstand明白míng bai了lea great deal很多hěn duō。

Through this affair, I came to understand a great deal.

Remember: 通过 = the MEANS, 使 = the EFFECT — "by way of X, it brings about Y" (通过锻炼，使身体更健康). Keep the two halves balanced: process first, result second.

Watch out

• Don't give both halves their own subject — it's the means-clause that 使 acts on, not a new actor.

以 … 的名义 states the authority or capacity an act is carried out under — "in the name of, on behalf of." Unlike 借…之名, it's neutral: it simply names whose name is being used.

Structure: 以 + Person / Body + 的名义 + Action

don't别biéin以yǐmy我wǒname的名义de míng yì给gěithe company公司gōng sīwrite to写信xiě xìn。

Don't write to the company in my name.

the court法院fǎ yuànin以yǐthe government's政府zhèng fǔname的名义de míng yìsued起诉qǐ sù了lehim他tā。

He was sued in the name of the government.

Remember: 以…的名义 = "in X's name / on behalf of" — NEUTRAL. It simply states the capacity an act is done under (以政府的名义). Its shady cousin is 借…之名 ("under the pretext of"): same idea, opposite tone.

Watch out

• No hidden agenda implied — for "under the guise of," you want 借…之名.

势必 (literally "the situation must …") asserts that circumstances make an outcome certain — "is bound to, will inevitably." It introduces the unavoidable result and is formal in tone.

Structure: …… ，势必 + inevitable result

carrying on这样zhè yànglike this下去xià qùis bound to，势必shì bìfail失败shī bài。

Carry on like this and failure is inevitable.

prices物价wù jiàrising上涨shàng zhǎngwill inevitably，势必shì bìaffect影响yǐng xiǎngpeople's人们rén men的delives生活shēng huó。

Rising prices are bound to affect people's lives.

Remember: 势必 = 势 (the circumstances) + 必 (must) = "the situation makes it inevitable." Stronger than a plain 一定 — it claims the circumstances themselves force the result. Formal.

Watch out

• It pins the certainty on circumstances — for a personal "definitely will," 一定 / 肯定 fit better.

倘若 is a highly literary "if, supposing, in the event that." Like 假使, it opens a hypothetical, with the result clause often taking 就 or 便. It belongs to formal prose and set polite phrases.

Structure: 倘若 + Condition ，(就 / 便) + Result

if倘若tǎng ruòthere is有yǒuany-不bùthing overlooked周到zhōu dào之处zhī chùplease，请qǐng多duōbear with us包涵bāo hán。

If anything has been overlooked, please bear with us.

if倘若tǎng ruòit fails失败shī bàiwe，我们wǒ menwill then再zàithink of想xiǎnganother别的bié deway办法bàn fǎ。

If it fails, we'll think of another way.

Remember: 倘若 = the most literary "if" — even dressier than 假使, at home in formal prose and set courtesies (倘若有不周之处, "if anything's been overlooked"). Result takes 就 / 便.

Watch out

• Reserve it for writing and polite set phrases — in speech use 如果 / 要是.

The 所 + Verb + 的 frame turns a verb into a formal noun phrase — "that which is …ed, what (one) …s." It names the object of the action in a measured, written tone. Dropping it (我想说的) means the same thing more plainly.

Structure: (Subject +) 所 + Verb + 的 (+ Noun)

this这zhèis exactly就是jiù shìwhat I我wǒ所suǒwant想xiǎngto say说shuō的de。

This is exactly what I want to say.

he他tā所suǒeverything he做zuòdoes的de一切yí qièis all都dōu是shìfor为了wèi leyou你nǐ。

Everything he does is for you.

Remember: 所 + verb + 的 = "that which is …ed" — a formal dressing-up. 我所想说的 = 我想说的 ("what I want to say"), just more literary. 所 flags the verb's object, so the verb is transitive.

Watch out

• It adds formality, not meaning — the plain 我想说的 says the same thing in speech.

何况 means "let alone, much less, all the more so." It pairs with a 连 … 都(也) … clause: first you state an extreme case (even A is true), then 何况 pushes to a case that's all the more so (so of course B). It's often a rhetorical question, closed with 呢; adding 更 / 又 before 何况 sharpens it.

Structure: Subject + 连 + A + 都(也) + Verb ，(更)何况 + B + 呢？

even连liánadults大人dà rén都dōufind it觉得jué dehard难nánlet alone，何况hé kuàngchildren孩子hái zi呢ne？

Even adults find it hard, let alone children.

this这zhèbit of点diǎnmoney钱qiáneven连liánfor food吃饭chī fàn都dōuisn't enough不够bú gòulet alone，何况hé kuàngbuying买mǎia house房fáng？

This bit of money isn't even enough for food, let alone buying a house.

Remember: 连 A 都…，(更)何况 B 呢？ = "even A…, LET ALONE B!" — it climbs from a strong case to an even stronger one (何况 = "how much more so"). Usually rhetorical, sealed with 呢; 更 / 又 before 何况 add punch.

Watch out

• It runs small → big (like 更不用说): A the lesser case, B the greater — don't flip them.

Both mean "according to," but they look at different things. 按照 means following a rule, plan, order or standard to the letter — "in accordance with." 根据 means drawing on evidence, grounds or a source — "on the basis of, going by"; it can also be a noun (有根据 = "well-grounded"), which 按照 cannot.

Structure: 按照 + rule / plan + Action · 根据 + evidence / source + Conclusion

please请qǐngin accordance with按照àn zhàothe rules规定guī dìngqueue up排队pái duì。

Please queue up in accordance with the rules.

going by根据gēn jùthe weather天气tiān qìforecast预报yù bàotomorrow，明天míng tiānwill会huìrain下雨xià yǔ。

Going by the forecast, it'll rain tomorrow.

Remember: 按照 = follow a RULE/plan ("by the book"); 根据 = reason from EVIDENCE ("going by the data"). 按照规定 (per the rules) vs 根据预报 (per the forecast). Only 根据 doubles as a noun (毫无根据, "groundless").

Watch out

• A rule to obey → 按照; grounds to infer from → 根据.

Both say you're forced into something unwanted, but the squeeze differs. 不得不 = there is no other choice at all — you simply can't avoid it (stronger, like 不得已). 只好 = there is no better choice — you settle for the least-bad option. Also, 不得不 must be followed by a positive verb; 只好 can take 不 / 没.

Structure: 不得不 + positive Verb · 只好 + Verb (可带 不 / 没)

going out出门chū ménwithout没méibringing带dàimoney钱qiánI had no choice but to，不得不bù dé bùfrom向xiànga friend朋友péng youborrow借jiè。

I went out without money, so I had no choice but to borrow from a friend.

outside外面wài mianit's下xiàpouring大雨dà yǔ了leI，我wǒhad no better option than to只好zhǐ hǎonot不bùgo out出去chū qù了le。

It's pouring outside, so I'll just not go out.

Remember: 不得不 = NO OTHER choice (forced, no escape); 只好 = NO BETTER choice (settle for least-bad). And the grammar tell: 不得不 takes only a positive verb, while 只好 can take 不 / 没 (只好不去).

Watch out

• You can't say 不得不不去 — for "had to not do," use 只好不去.

Both describe something that keeps going. 不断 = "continually, again and again" — a process that repeats or grows over time (it can imply increase), and as an adverb it often takes 地. 不停 = "without a pause" — the action literally never stops for a moment, often as V + 个不停 or 不停地 + V.

Structure: 不断(地) + Verb · 不停地 + Verb / Verb + 个不停

technology科技kē jìis在zàicontinually不断bú duàn地deadvancing进步jìn bù。

Technology is continually advancing.

she她tāwas so excited激动jī dòngthat she得detalked说shuōwithout stopping个不停gè bù tíng。

She was so excited she talked non-stop.

Remember: 不断 = "again and again / growing over time" (断 = "break," so 不断 = "unbroken, recurring"); 不停 = "no pause at all" (停 = "stop"). 不断进步 (keeps advancing) vs 说个不停 (talks non-stop). 个不停 clips onto the verb: 笑个不停.

Watch out

• 不断 allows gaps that keep recurring; 不停 means literally no pause.

Both mark a turn, but with different force. 反而 = "on the contrary, instead" — the result is the opposite of what you'd expect, and it can sit before or after the subject. 却 = a milder "but, yet," and it can only come after the subject. 反而 often completes the pattern 不但没 / 不但不 …，反而 ….

Structure: (Subj.) 反而 + opposite outcome · Subj. + 却 + contrast

I我wǒhelped帮bāng了lehim他tāyet he，他tāon the contrary反而fǎn érgot angry生气shēng qì了le。

I helped him, yet he got angry instead.

she她tālikes喜欢xǐ huansweets甜食tián shíbut，却quènever从不cóng bùeats吃chīchocolate巧克力qiǎo kè lì。

She likes sweets, but never eats chocolate.

Remember: 反而 = the OPPOSITE of what you'd expect (a reversal); 却 = a plain "but / yet" (a contrast). 反而 can go before or after the subject and completes 不但没…反而…; 却 only sits after the subject.

Watch out

• 却 can't lead the clause — 她却…, never 却她…; 反而 is freer.

根本 = "(not) at all, simply, fundamentally" — it intensifies a negation (根本不 / 根本没), flatly denying something. 到底 = "after all, in the end" or, in a question, "on earth / exactly" — it presses for the final result or truth. You can't swap them.

Structure: 根本 + 不 / 没 + Verb · 到底 + Question

I我wǒsimply根本gēn běndidn't没méigo out出去chū qùhow，你nǐ怎么zěn mecould会huìhave seen看到kàn dàome我wǒ？

I didn't go out at all — how could you have seen me?

you你nǐon earth到底dào dǐwhat do you want想xiǎng怎么样zěn me yàng？

What on earth do you want?

Remember: 根本 intensifies a NEGATION ("not at all": 根本不/没); 到底 presses for an ANSWER ("on earth / in the end"). One flatly denies, the other demands the truth. In a statement, 到底 = "after all, it turned out…".

Watch out

• 根本 leans on a following 不 / 没; 到底 leans on a question word or a result.

These overlap in meaning — "according to, on the basis of" — but differ in style. 据 is terse and literary, and pairs with single-character or short items (据说, 据实, 据悉). 根据 is the everyday word, takes two-or-more-character objects, and can also act as a noun.

Structure: 据 + short word + Clause · 根据 + (longer) source + Clause

it is据jùsaid说shuōhe，他tāhas already已经yǐ jīnggone abroad出国chū guó了le。

It's said he's already gone abroad.

according to根据gēn jùthe survey调查diào cháresults结果jié guǒeveryone，大家dà jiā都dōuis very很hěnsatisfied满意mǎn yì。

According to the survey results, everyone is very satisfied.

Remember: 据 = terse/literary + SHORT items (据说, 据悉, 据实); 根据 = everyday + longer objects, and a noun too. Same idea, opposite ends of the formality scale.

Watch out

• 据 wants a tight, short partner (据说 ✓); a longer source takes 根据 (根据调查结果).

Both mean returning to a former state, but with a different feel. 恢复 = "recover, restore" something that was damaged, disrupted or lost — health, order, normal service. 还原 = "return to the exact original state, reset, reduce" — it stresses going back precisely to how it was (it's also the chemistry term "reduce").

Structure: 恢复 + Noun (health / order) · 把 … 还原 (成 …)

after经过jīng guòtreatment治疗zhì liáohe，他tā的dehealth身体shēn tǐslowly慢慢màn mànrecovered恢复huī fù了le。

After treatment, his health slowly recovered.

you你nǐcan可以kě yǐ把bǎthe settings设置shè zhìrestore还原huán yuánto成chéngthe defaults默认值mò rèn zhí。

You can reset the settings to the defaults.

Remember: 恢复 = bring back something DAMAGED/lost (health, order); 还原 = return to the EXACT original / reset. 恢复健康 (recover) vs 还原设置 (reset to factory). 还原 stresses precisely as before, with no "was broken" overtone.

Watch out

• For health/order coming back, it's 恢复 — 还原 sounds like a reset/reduction.

Both flag the unexpected, but differently. 居然 = "surprisingly, to one's astonishment" — it simply marks the event as astonishing, often letting the speaker tack on a comment. 反而 = "on the contrary" — it marks a reversal, the opposite of what should have followed, and pairs with 不但没 / 不但不 …，反而 …, where 居然 can't.

Structure: 居然 + astonishing fact (+ comment) · 不但没 / 不但不 …，反而 …

he他tāso这么zhè meyoung小xiǎoastonishingly居然jū ráncan能néngrecite背bèihundreds of几百jǐ bǎi首shǒuTang poems唐诗Táng shītruly，真zhēnremarkable了不起liǎo bu qǐ。

So young, yet he can recite hundreds of Tang poems — truly remarkable.

after taking吃chī了lethese这些zhè xiēpills药yàohe，他tānot only不但bú dàndidn't没méiget better好hǎobut instead，反而fǎn érgot even更gèngworse严重yán zhòng了le。

After taking these pills, not only did he not improve — he got worse.

Remember: 居然 = "astonishingly!" (just marks surprise, + optional comment); 反而 = "on the contrary" (a reversal). Only 反而 completes 不但没 / 不但不 …，反而 …. 居然 is amazement; 反而 is a flip.

Watch out

• A surprise that isn't a reversal takes 居然; the "opposite happened" twist takes 反而.

Both touch on time but mean different spans. 一度 = "once, at one time" — a past phase (often a difficult one: 一度想放弃), and it appears in 一年一度 ("annual"). 一时 = "for a short while, momentarily, for the moment" — brief or sudden, often "can't … right now" (一时想不起来).

Structure: 一度 + past Verb phrase · 一时 + (不能) Verb

he他tāin the past过去guò qùat one time一度yí dùwanted to想xiǎnggive up放弃fàng qì。

At one point in the past he wanted to give up.
