on the contrary反而标示出and / with与to expect预期opposite相反(modifier / structural particle)的outcome结果 — "on the contrary, instead, actually"。it它to be / is是一个adverb副词，therefore因此to place in置于subject (in grammar)主语after之后、verb动词before之前（不同于conjunction连词 but但是，it它to guide引导clause (grammar)分句）。它常one's conduct作为 not only (... but also ...)不但 / not just不仅 + not / haven't没 … on the contrary反而 … structure结构(modifier / structural particle)的half一半to appear出现。
โครงสร้าง: …… ，Subject + 反而 + Unexpected Outcome
taking吃了the medicine药the illness，病actually反而even更worse严重了。
Taiwan pr.服(completed / change)了medicine药after之后，illness病on the contrary反而to make heavier加重(completed / change)了。
he他not only不但didn't没give up放弃but actually，反而even更harder努力了。
not only非但not have / haven't没有to renounce放弃，on the contrary反而more更to make an effort努力(completed / change)了。
to remember记住： on the contrary反而 = "instead, beyond expectation (idiom)出乎意料(modifier / structural particle)的reverse side反面" — 一个 tucked at / in在subject (in grammar)主语after之后 (modifier / structural particle)的adverb副词 (he / him他on the contrary反而…, in no way绝不variant of 说说 on the contrary反而he / him他…)。它常to complete完成 not only (... but also ...)不但/not just不仅 + not / haven't没/not不 … ，on the contrary反而 … (modifier / structural particle)的structure结构 ("far from …ing, actually …")。
ข้อควรระวัง
- don't不要to resemble像English (language)英语 "instead" that way那样放在start of phrase or sentence句首 — it它to answer应to place in置于verb动词front前，at / in在clause从句interior内部。
