英語必修三語法：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)詞的語法特征
情態(tài)動(dòng)詞 不能單獨(dú)做謂語，除ought 和have 外，后面只能接不帶to 的不定式。
情態(tài)動(dòng)詞沒有人稱，數(shù)的轉(zhuǎn)變，但有些情態(tài)動(dòng)詞，如can、will也有一樣平時(shí)式和已往式的轉(zhuǎn)變。
情態(tài)動(dòng)詞的“時(shí)態(tài)”形式并不是時(shí)間區(qū)其余主要標(biāo)志，不少情形下，情態(tài)動(dòng)詞的現(xiàn)在式形式和已往式形式都可用來示意現(xiàn)在時(shí)間、已往時(shí)間和未來時(shí)間。
can, could 和be able to的用法
can, be able to都可示意“能力”
Can的主語是人或物,be able to的主語是人
She can/be able to sing the song in English.
This machine can make you feel comfortable.

could用于示意泛指已往的能力。如：
