英語(yǔ)必修三語(yǔ)法：情態(tài)動(dòng)詞

情態(tài)助動(dòng)詞有十三個(gè)：

may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to.

情態(tài)動(dòng)詞的語(yǔ)法特征

1）情態(tài)動(dòng)詞 不能單獨(dú)做謂語(yǔ)，除ought 和have 外，后面只能接不帶to 的不定式。

2）情態(tài)動(dòng)詞沒(méi)有人稱，數(shù)的變化，但有些情態(tài)動(dòng)詞，如can、will也有一般式和過(guò)去式的變化。

3）情態(tài)動(dòng)詞的“時(shí)態(tài)”形式并不是時(shí)間區(qū)別的主要標(biāo)志，不少情況下，情態(tài)動(dòng)詞的現(xiàn)在式形式和過(guò)去式形式都可用來(lái)表示現(xiàn)在時(shí)間、過(guò)去時(shí)間和將來(lái)時(shí)間。

can, could 和be able to的用法

1.can, be able to都可表示“能力”

Can的主語(yǔ)是人或物,be able to的主語(yǔ)是人

2.can只用于現(xiàn)在式和過(guò)去式(could)。be able to可以用于各種時(shí)態(tài)。
