无敌英语语法(初级版)-第12章 4 would和should
would是will的过去式,Would you~?作为情态动词,表示“可以请你~吗?”
should是shall的过去式,作为情态动词时,则表示“应该~”。
1 would的用法(请记住以下几个句型)
Would you have a cup of tea?
可以请你喝杯茶吗?
1.Would you~?和Will you~?
这两个句型皆表示客气的请求、劝说……,但Would you~?更客气些。
Would you tell me the way to the station?
劳驾,您能告诉我去车站怎样走吗?
(回答同《Will you~?》句型)
2.主语+would like to~
表示“想要……”的意思上,与…want to~意思一 样,但用此句型较客气。
I want to ask you a question.
=I'd(I would)like to ask you a question.
我想问你一个问题。
3.Would you like~?
表示请求、劝说,是很客气的说法。
Would you like a cup of tea?
您愿意喝杯茶吗?
Would you like to sing a song?
请唱首歌好吗?
注意
I'd读为〔aid〕
=I would
=I should
=I had
2 should的用法
You should read this book.
你应该读这本书。
1.should(应当、应该)用于所有人称,与ought to~同义。
You should wait a little more.
=You ought to wait a little more.
你应该再多等一会儿。
2.在表示要求、命令时,语气是由should(应该)、
~had better(最好)、~must(必须)逐渐加强。
had better
had better相当于一个助动词,它后面要跟动词原形;had better只有一种形式,没有has,have better这一形式;它的否定式是在它后面加not。
You had better go now.你最好现在走。
He'd(=He had)better do it now.他最好现在做。
She'd better not cry.她最好别哭。
