The verb "to be" means "is / am / are." It changes according to the subject and has three forms:

• I → am
• he / she / it → is
• you / we / they → are

我I 是am 一名a 学生student.

I am a student.

她She 是is 开心happy.

She is happy.

他们They （是）are 来自from 中国China.

They are from China.

Note: Common spoken contractions: I'm, you're, he's, she's, it's, we're, they're.

Negation: Add not after the be verb (often contracted).

他He 不是is not 一名a 老师teacher.

He is not a teacher. (= He isn't a teacher.)

Interrogative: Place the be verb before the subject.

（是吗）Are 你you 准备好ready?

Are you ready?

Short answers: Yes, I am. / No, I'm not.

Note: Negative contractions: is not → isn't, are not → aren't; but am not is only contracted to I'm not (there is no ~~amn't~~).

Common Errors

• ❌ ~~He busy.~~ → ✓ He is busy. — In Chinese, "He is very busy" can exist without a verb, but an English sentence must have a verb. Use be to link when the predicative is an adjective or noun and there are no other verbs in the sentence (He is busy); do not add be if the sentence already contains an ordinary verb (I go to school).
• ❌ ~~I am go to school.~~ → ✓ I go to school. — Do not use be and ordinary verbs together; "go" alone suffices for "to go."
• ❌ ~~They is my friends.~~ → ✓ They are my friends. — Plural subjects (you / we / they) take are.
• ❌ ~~I am agree.~~ → ✓ I agree. — agree is itself a verb; do not add am before it.
• ❌ ~~Are you ready? — Yes, I'm.~~ → ✓ Yes, I am. — Contractions cannot be used at the end of affirmative short answers (say Yes, I am); however, negative short answers typically end with a negative contraction (No, he isn't / No, I can't; first person is No, I'm not, as there is no amn't).

Subject pronouns replace the subject and are placed before the verb:

• I(I), you(you), he(he), she(she)
• it(it), we(we), they(they)

他He 是is 我的my 哥哥brother.

He is my brother.

我们We 喜欢like 音乐music.

We like music.

Key Usage Points:

• I is always capitalized, regardless of its position in the sentence.
• Things and animals commonly use it: This is my bag. It is new.(This is my bag. It is new.)*
• Plural people or things both use they: The books are here. They are mine.(The books are here. They are mine.)*

Note: Subject pronouns are followed by verbs; do not confuse them with object pronouns (me, him, her...) which will be learned later.

Common Errors

• ❌ ~~My mother is a doctor. He is very kind.~~ → ✓ She is very kind. — In colloquial Chinese, "he/she" sounds identical, but in English, he and she must be clearly distinguished.
• ❌ ~~Me am a student.~~ → ✓ I am a student. — Use I for the subject, not me.
• ❌ ~~My friend he is tall.~~ → ✓ My friend is tall. — The subject needs to be mentioned only once; avoid repeating "noun + pronoun" (the Chinese habit of saying "my friend he..." does not apply in English).
• ❌ ~~Is raining.~~ → ✓ It is raining. — English sentences must have a subject; weather, time, and dates begin with it.

Possessive adjectives indicate "whose" and are placed before the noun:

• I → my(my), you → your(your), he → his(his)
• she → her(her), it → its(its), we → our(our), they → their(their)

这This 是is 我的my 包bag.

This is my bag.

她的Her 名字name 是is 露西Lucy.

Her name is Lucy.

Key Usage Points:

• Possessive adjectives are always followed by a noun: my book, their house.
• They do not change with noun number: my book, my books(my remains unchanged).

Note: Be careful to distinguish its (its, no apostrophe) and it's (= it is). For example: The dog wags its tail.(The dog wags its tail.)*

Common Errors

• ❌ ~~This is she book.~~ → ✓ This is her book. — A possessive form must precede a noun: he → his, she → her.
• ❌ ~~He is me friend.~~ → ✓ He is my friend. — The possessive form of I is my.
• ❌ ~~The dog wags it's tail.~~ → ✓ …wags its tail. — it's = it is; "its" (possessive) has no apostrophe.
• ❌ ~~Their is a park near here.~~ → ✓ There is a park near here. — their (their) and there (there/here) sound identical; do not mix them up in writing.

Demonstratives point out "which one." Use this and that for singular:

• this(this): Close to the speaker.
• that(that): Far from the speaker.

这This 是is 我的my 手机phone.

This is my phone. (Close)

那That 是is 你的your 车car.

That is your car. (Far)

Use these and those for plural:

• these(these): Close. those(those): Far.

这些These 是are 我的my 书books.

These are my books.

那些Those 是are 她的her 朋友friends.

Those are her friends.

Contrastive Memory:

• Near → this (singular) / these (plural).
• Far → that (singular) / those (plural).

Note: These / those are followed by plural nouns: these books, not ~~these book~~.

Common Errors

• ❌ ~~these book~~ → ✓ these books — Plural nouns must follow these / those.
• ❌ ~~This books are mine.~~ → ✓ These books are mine. — If the noun is plural, the demonstrative must also be plural.
• ❌ When introducing yourself on the phone, say ~~I am Tom.~~ → ✓ This is Tom. — In English, introduce yourself on the phone using this is.
• Remember pairs: Near this / these are often used with here; far that / those are often used with there.

a and an mean "one" and are used before singular countable nouns. How to choose depends on pronunciation:

• a + consonant sound: a book, a dog, a cat.
• an + vowel sound: an apple, an egg, an orange.

我I 有have 一个a 笔pen.

I have a pen.

她She 吃eats 一个an 苹果apple.

She eats an apple.

Note: Look at the sound, not the letter: an hour (h is silent), a university (pronounced "yu-").

To indicate "more than one," use the plural form of the noun, usually adding -s:

• Generally add -s: book → books, car → cars.
• Words ending in -s / -sh / -ch / -x add -es: bus → buses, box → boxes.
• Consonant + y ending: change y to i and add -es: baby → babies, city → cities.

我I 有have 两two 猫cats.

I have two cats.

Irregular plurals (must memorize):

• man → men, woman → women, child → children.
• foot → feet, tooth → teeth, person → people.

Note: Do not use a / an before plural nouns: ~~a books~~ ✗ → books / two books ✓.

Common Errors

• ❌ ~~I have dog.~~ → ✓ I have a dog. — In Chinese you can say "I have dogs," but singular countable nouns in English must have a / an (or my, the, etc.) before them.
• ❌ ~~an university~~ → ✓ a university; ❌ ~~a hour~~ → ✓ an hour — Look at pronunciation, not spelling: university starts with a consonant sound /j/, and h is silent in hour.
• ❌ ~~two book~~ → ✓ two books — Chinese nouns do not change for plurality, but nouns after numbers in English require -s; this is easily forgotten.
• ❌ ~~three childs~~ → ✓ three children — Irregular plurals must be memorized separately: men, women, children, feet, teeth, people.
• ❌ ~~a people~~ → ✓ a person (one person) / people (many people) — people is inherently plural.

there is / there are means "there exists" (something exists somewhere).

• There is + singular / uncountable noun: There is a book.
• There are + plural noun: There are two books.

（有）There 有is 一只a 猫cat 在on （冠词）the 沙发上sofa.

There is a cat on the sofa.

（有）There 有are 三three 书books 在on （冠词）the 桌上desk.

There are three books on the table.

Note: In spoken English, there is is often contracted to there's: There's a problem.

Negative: there is not / there are not (contracted as there isn't / there aren't).

（有）There 没有isn't 任何any 牛奶milk.

There is no milk left.

Question: Move is / are to the front of there.

（有吗）Is （有）there 一家a 银行bank 附近near 这里here?

Is there a bank nearby?

Short answer: Yes, there is. / No, there isn't.

Note: Use any frequently in negative / question sentences: Is there any water? (Is there any water?)

Common Errors

• ❌ ~~Here has many people.~~ → ✓ There are many people here. — The "have" in the Chinese "There are many people here" indicates existence; use there is / there are in English, do not translate literally as have.
• ❌ ~~There have a book on the desk.~~ → ✓ There is a book on the desk. — Use is / are after there; there have does not exist.
• ❌ ~~There is two cats.~~ → ✓ There are two cats. — If the following noun is plural, use are.
• ❌ ~~There are a milk.~~ → ✓ There is some milk. — milk is uncountable: use there is + some, do not use a.

have got means "to possess" (= have), common in British English.

• I / you / we / they → have got
• he / she / it → has got

我I 有have got 一个a 兄弟brother.

I have a brother. (= I have a brother.)

她She 有has got 蓝色blue 眼睛eyes.

She has blue eyes.

Note: Often contracted in spoken language: I've got, she's got, they've got. Same meaning as have / has.

Negative: haven't got / hasn't got.

他He 没有hasn't got 一辆a 车car.

He doesn't have a car.

Question: Move Have / Has to the front of the subject.

（有吗）Have 你you 有got 一支a 笔pen?

Do you have a pen?

Short answer: Yes, I have. / No, I haven't.

Note: have got is mostly used for current possession; for past or habits, use regular have / had.

Common Errors

• ❌ ~~She have got long hair.~~ → ✓ She has got long hair. — Use has got for he / she / it.
• ❌ ~~I have got not a car.~~ → ✓ I haven't got a car. — Place not after have / has, then contract.
• ❌ ~~Do you have got a pen?~~ → ✓ Have you got a pen? / Do you have a pen? — Both question forms are correct, but never mix them.
• ❌ ~~Yes, I have got.~~ → ✓ Yes, I have. — Short answers end at have / has, without got.

Present simple (present simple) describes habits and facts. The base form is the infinitive (base verb).

我I 喜欢like 茶tea.

I like tea.

When the subject is he / she / it, add -s to the verb:

他He 踢plays 足球football.

He plays football.

Spelling rules:

• Generally add -s: like → likes.
• Words ending in -s / -sh / -ch / -x / -o add -es: go → goes, watch → watches.
• Consonant + y ending: change y to i and add -es: study → studies.

Note: Only he / she / it take -s; I / you / we / they use the base form: They like tea.

For negatives and questions, use auxiliary verbs do / does (does for he / she / it).

Negative: Subject + don't / doesn't + base verb.

我I 不don't 喜欢like 咖啡coffee.

I don't like coffee.

Question: Do / Does + Subject + base verb ?

（助动词）Does 她she 住live 这里here?

Does she live here?

Note: When using do / does, the verb returns to its base form (no -s): ~~Does she lives~~ ✗ → Does she live ✓.

Common Errors

• ❌ ~~He go to school by bus.~~ → ✓ He goes to school by bus. — Forgetting to add -s in third person singular is the most frequent error; check your work afterwards.
• ❌ ~~She doesn't likes coffee.~~ → ✓ She doesn't like coffee. — When using does / doesn't, the verb returns to its base form.
• ❌ ~~I very like English.~~ → ✓ I like English very much. — "Very much" in Chinese cannot be translated literally; very cannot directly modify a verb.
• ❌ ~~You like tea?~~ → ✓ Do you like tea? — Questions must start with do / does; rising intonation alone is insufficient.

can expresses ability ("know how to / be able to") or is used for requests. It is followed by the base form of the verb, and remains the same for all persons.

我I 会can 游泳swim.

I can swim.

能Can 你you 帮help 我me?

Can you help me?

Note: Use the base form after can: ~~can to swim~~ ✗, ~~can swims~~ ✗ → can swim ✓.

Negative: cannot (abbreviation can't) + base form of the verb.

她She 不会can't 开车drive.

She cannot drive.

Question: Place Can before the subject.

能Can 他he 做饭cook?

Can he cook?

Short answer: Yes, I can. / No, I can't.

Note: can has no -s and does not use do/does: ask directly with Can he…?, not ~~Does he can…?~~

Common Errors

• ❌ ~~She cans drive.~~ → ✓ She can drive. — can has no third-person singular -s; it is the same for all persons.
• ❌ ~~I don't can swim.~~ → ✓ I can't swim. — The negative of can is formed directly with not (can't), without using don't.
• ❌ ~~He can sings very good.~~ → ✓ He can sing very well. — Use the base form of the verb after can; use the adverb well to modify a verb, not good.
• ❌ ~~You can help me?~~ → ✓ Can you help me? — When making a request, place can before the subject.

Imperatives are used to give commands, provide instructions, or make requests. Start directly with the base form of the verb, without a subject.

打开Open （冠词）the 门door 请, please.

Please open the door.

坐Sit 下down.

Sit down.

Negative: Add Don't at the beginning.

不要Don't （是）be 迟到late.

Don't be late.

Key Usage Points:

• Add please to be more polite: Please come in.
• Also used for directions and instructions: Turn left. Mix the eggs.

Note: Do not write a subject in imperatives: ~~You open the door~~ (for a command) → Open the door.

Common Errors

• ❌ ~~Please open door.~~ → ✓ Please open the door. — Articles must still be included in imperatives.
• ❌ ~~Don't to touch it.~~ → ✓ Don't touch it. — Follow don't directly with the base form of the verb; do not add to.
• ❌ ~~No talk in class!~~ → ✓ Don't talk in class! / No talking! — To prohibit an action, use don't + base form; after no, use -ing or a noun.
• ❌ ~~You sit down!~~ → ✓ Sit down, please. — Adding you to a command sounds angry; add please for politeness, or change to Can you…?

Question words are placed at the beginning of a question to ask for specific information.

• what (what), where (where), who (who)

什么What 是is 你的your 名字name?

What's your name?

哪里Where （助动词）do 你you 住live?

Where do you live?

谁Who 是is 那个that 男人man?

Who is that man?

Note: A be verb or auxiliary do/does often follows the question word: Where do you work?

• when (when), why (why), how (how / in what way)

什么时候When 是is （冠词）the 派对party?

When is the party?

为什么Why （是）are 你you 难过sad?

Why are you sad?

怎么How （助动词）do 你you 拼写spell 它it?

How do you spell this?

Note: how can also combine with adjectives to ask about degree: How old are you? How much is it?

Common Errors

• ❌ ~~Where you live?~~ → ✓ Where do you live? — After the question word, you still need do/does or be; you cannot follow directly with the subject.
• ❌ ~~What means this word?~~ → ✓ What does this word mean? — mean is an ordinary verb: question word + does + subject + base form.
• ❌ ~~Why you are late?~~ → ✓ Why are you late? — When there is a be verb in the sentence, move be before the subject.
• ❌ ~~How to spell it?~~ → ✓ How do you spell it? — A literal translation of "How to spell?" loses the subject and auxiliary verb; these must be added.

Prepositions of place indicate where something is located.

• in (inside...), on (on top of... / surface), under (below...)

（冠词）The 钥匙keys 在are 在...里in （冠词）the 包里bag.

The key is in the bag.

（冠词）The 书book 在is 在...上on （冠词）the 桌上table.

她She 坐sits 之间between 汤姆Tom 和and 萨姆Sam.

She sits between Tom and Sam.

Note: between means "between two," and is usually followed by A and B: between the door and the window.

Common Errors

• ❌ ~~The picture is in the wall.~~ → ✓ The picture is on the wall. — Hanging "on" the wall involves surface contact, so use on.
• ❌ ~~I read it on the book.~~ → ✓ ...in the book. — Content "inside" a book uses in; people in photos also use in the photo.
• ❌ ~~The shop is next the bank.~~ → ✓ next to the bank — next to is two words; to cannot be omitted.
• ❌ ~~between the door with the window~~ → ✓ between the door and the window — between takes the fixed collocation A and B.
