'Wouldn't' is the short form of 'would not', and it covers a surprising amount of ground.

'Wouldn't' Wouldn't is是 'would not' would not the short form of的縮寫 and it covers而它涵蓋的範圍 a surprising amount of ground大得驚人。

It carries the negative half of an if-sentence: "I wouldn't say that if I didn't mean it." It softens a refusal or an opinion to be polite: "I wouldn't recommend the fish." "I wouldn't if I were you." It reports a past refusal — this is the one students underuse: "The car wouldn't start." "He wouldn't tell me where he'd been." Notice that this last use is not about the future or the imaginary at all; it is a plain past fact, and it works for machines as well as people. English quietly treats a car that won't start as something stubbornly refusing, and 'wouldn't' is how we say it.

It它 carries承載著 of an if-sentence假設句的 the negative half否定那一半： "I wouldn't say that if I didn't mean it."不是真心的話，我不會那樣說。 It它 to be polite為了禮貌 softens會軟化 a refusal or an opinion拒絕或意見： "I wouldn't recommend the fish."我不太推薦這道魚。 "I wouldn't if I were you."我是你的話就不會。 It它 reports報告 a past refusal過去的「不肯」 — this is這是 the one students underuse學生最少用的那一個： "The car wouldn't start."車子就是發不動。 "He wouldn't tell me where he'd been."他就是不肯告訴我他去了哪裡。 Notice that注意 this last use最後這個用法 is not about完全不是在講 the future or the imaginary at all未來或想像； it is它是 a plain past fact平實的過去事實 and it works而且 for machines對機器 as well as people和對人都適用。 English英文 quietly悄悄地 treats把 a car that won't start發不動的車 as當成 something stubbornly refusing頑固拒絕的東西 and 'wouldn't'而 wouldn't is how we say it就是我們說這件事的方式。

It also describes what someone habitually refused to do in the past: "She wouldn't eat vegetables as a child." In speech we almost always contract it; the full 'would not' is what you say when you are being emphatic or formal — "I would not do that." In pronunciation, remember the 'l' is silent: WOOD-nt.

It它 also describes也描述 in the past過去 someone habitually refused to do某人習慣性不肯做 what的事： "She wouldn't eat vegetables as a child."她小時候就是不肯吃青菜。 In speech在口語裡 we我們 almost always contract it幾乎總是用縮寫； when you are being emphatic or formal你在強調或正式的時候 the full 'would not'完整的 would not is what you say才是你會說的 — "I would not do that."我絕不會那麼做。 In pronunciation發音上 remember記得 the 'l' l is silent不發音： WOOD-nt唸 WOOD-nt。

The apostrophe is not decoration; 'wouldnt' is a spelling error. In formal essays, write 'would not' in full; in speech, messages, and dialogue, 'wouldn't' is normal and correct.

The apostrophe那個撇號 is not decoration不是裝飾； 'wouldnt' wouldnt is a spelling error是拼字錯誤。 In formal essays在正式文章裡 write 'would not' in full把 would not 完整寫出來； in speech, messages, and dialogue在口語、訊息和對話裡 'wouldn't' wouldn't is normal and correct是正常而且正確的。

It is also the backbone of many polite fixed phrases: 'I wouldn't mind…', 'wouldn't you agree?', 'I wouldn't know', 'it wouldn't hurt to ask'.

It它 is also也是 of many polite fixed phrases許多客氣固定說法的 the backbone骨幹： 'I wouldn't mind…'我不介意…、 'wouldn't you agree?'你不覺得嗎？、 'I wouldn't know'我哪會知道、 'it wouldn't hurt to ask'問一下也無妨。
