would的用法

一種表示征求許可的表達(dá)

Would it be OKif……

一種非正式的征求同意的表達(dá)

還可以說成Would it be alright if……

Would it be alright if i did this tomorrow?

Would it be OKif ，would it be alright if 這兩種表達(dá)之后的動(dòng)詞要用虛擬語(yǔ)氣，過去式，如果你用現(xiàn)在時(shí)，也是可以的，只是聽起來不是那么正式

would it be alright if i do this tomorrow?

如果你想更禮貌一些，可以試試這么表達(dá)吧

would i be able to

would I be able to talk to you this things?

當(dāng)然還有一些其他的表達(dá)方法，需要靈活運(yùn)用，根據(jù)自己所面對(duì)的情況而定，如，熟悉的人或是不熟悉的人，你想要給對(duì)方留下一個(gè)什么樣的印象：

Is it OKif i leave late?

can he sit here?

Do you mind if I sit here?

Can I help you?

但是如果要想正式或禮貌一些，不妨試試這種問法

Could I have that?

Could I see you？

Could you give that to me?

這一次聽起來有些禮貌了，但是任何時(shí)候想要表示禮貌都要記得加上 please

不管什么時(shí)候征求許可，加please都不會(huì)錯(cuò)。
