沒有人稱和數(shù)的變化。1.“能、會”,表示“能力”(有時態(tài)的變化)IcanspeakEnglish.

1.不能獨(dú)立作謂語，只能和動詞原形一起構(gòu)成謂語，表示說話人的語氣和情態(tài)。2.沒有人稱和數(shù)的變化(即無三單形式)。(haveto除外)3.否定形式：在其之后加not(haveto除外)。疑問形式：情態(tài)動詞提到主語之前(haveto除外)。might,can,must它們都是____動詞，用來表達(dá)某種感情。

1.might意思是“________”。

2.can意思是“________”。

3.must意思是“______”。（主觀）

4.haveto意思是“______”。（客觀）Grammar情態(tài)必須不得不能；會可能；也許1.can/may都可表示“許可”。may用于較正式、客氣的場合，而can比較隨便（口語）。

Youmay/cansmokehere.Thepolicemansaysyoucan’tparkhere.2.情態(tài)動詞“haveto”與其他的情態(tài)動詞如“can”,“may”“must”和“should”不同。1)這4個情態(tài)動詞沒有人稱的變化,而haveto有,它的第三人稱單數(shù)為“hasto”如：

Heshouldstudyhard.Hehastostudyhard.3.must/havetomust表示主觀上覺得“必須...”；

haveto表示客觀需要，即“不得不”,根據(jù)客觀原因而不得不做某事。
