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。

现在should 或 would 这两个词中的任何一个都可以用于第一人称,表示条件式中的将来:
If I had known that, I would (or somewhat more formally, should ) have answered differently.
如果已经知道了这个情况的话,我就(或正规一点用 should ) 不会那么回答了 ,
2 But in the second and third persons only would is used:
但在第二人称或第三人称中只用would :
If he had known that, he would (not should ) have answered differently.
如果他知道那个情况的话,就(不能用 should ) 不会那么回答了。
3 Wouldcannot always be substituted for should, however. Should is used in all three persons in a conditional clause:
但是Would并不是总是能由 should 代替。 Should 在三种人称的条件从句中都可以用:
if I (or you or he ) should decide to go.
如果我(或 你 或 他 ) 决定要去。
4 Should is also used in all three persons to express duty or obligation (the equivalent of ought to ):
Should用于这三种人称的表示职责和义务的句子中(相当于 ought to ):
I (or you or he ) should go.
我(或者 你 或者 他 ) 应该去 。
