情態(tài)動詞是中考?？伎键c。情態(tài)動詞本身有一定的意義，但是不能獨立做謂語，必須和動詞原形一起構(gòu)成句子的謂語部分。另外，情態(tài)動詞沒有人稱和數(shù)的變化，也就是說主語是第三人稱單數(shù)時情態(tài)動詞后邊不加-s；情態(tài)動詞沒有非謂語形式，即沒有不定式、分詞、動名詞形式。由此看來，說它“用情專一”一點都不為過。

一、常見情態(tài)動詞的用法

1. can

①表示“會、能夠”，指具備某種能力。如：

Lang Lang can play the piano very well. 郎朗鋼琴彈得很好。

I cant swim at all. 我根本不會游泳。

②和may一樣，表示“請求或許可”。如：

Can / May I come in？ 我可以進來嗎？

Can / May you give me a hand？ 你能幫我一下嗎？

③表示“懷疑、不確定或猜想”。如：

Can it be true？ 那是真的嗎？

He cant be a student. 他不可能是一個學(xué)生。

④could除了做can的過去式外，還可表示一種委婉的語氣或用于不太肯定的推測。如：

Could you come with me？ 你能和我一起去嗎？

The bike could be Toms. 那輛自行車可能是湯姆的。

⑤be able to意為“能、會”，和can的意思基本一樣。be able to強調(diào)通過努力而獲得的能力；而can則強調(diào)自身已具有的能力。另外，can只有兩種時態(tài)（一般現(xiàn)在時和一般過去時）；而be able to可以有多種時態(tài)。如：

I hope Chinese Womens Volleyball team will be able to win the Olympic gold medal. 我希望中國女排能夠贏得奧運會金牌。

You will be able to pass the exam if you work hard at it. 只要你努力，你就會考試及格。

Luckily， he was able to win the match in the end. 幸運的是，他終于贏得了比賽。
