I’d 是什么意思？用法？

是一种缩写
I would/should/could/had都是有可能的

I would最常用,后面接动词原型,意思是"我想(做某事)","我希望(做某事)"
也可能是I would like somebody to do something.意思是"我想要某人做某事"

I had也比较常用,其实完整的应该是I had better,后面也是加动词原型.意思是"我最好还是(做什么什么事)"

I could 后面接动词原型,意思是我可以/能够做某事,是过去时态
也可以接have done,是虚拟语气,意思是我本来可以做某事的(但是没有做)

I should 后面也是既可以接动词原型,表示我应该做某事;也可以接have done,表示我应该去做某事的(但是没有做)

I’d = I would

以I would like to do sth为例:

I'd like it do.
我希望把此事完成。
I'd like to go.
我想去
I 'd like fish.
我想吃鱼。
I 'd like that!
这个主意好！
I'd like a bob.
我想留短发。

i'd = i would或者i had(不常用）
i would like to do sth...=====

I would 的缩写

I would like to do sth.
