情態動詞
情態動詞本身有一定的含義，但不能單獨作謂語，后跟行為動詞原形一起構成謂語，表示說話人的語態和情態。情態動詞沒有人稱和數的變化。
can, could, may, might, shall, should, must, need, dare, ought to, will, would, used to.
幫你歸納
1.— Could I cross the street here?
— Of course you____.
A. could B. can C. be able to D. will
思路點撥： 此句中的could 表示委婉的語氣，而不是表示過去時態。故回答時應用can，表示能夠干某事。
2. Some people think trees _____ on Tree Planting Day only.
A. should be planted B. should plant
C. should be planting D. be planted
思路點撥：表“義務”和“應該”時，用should。情態動詞的被動語態為：情態動詞+ be +done。
3.— Must I do the work now?
— No, you _____ . You may do it later.
A. can’t B. mustn’t C. needn’t D. shouldn’t
思路點撥：用must 引導的一般疑問句，其回答形式：肯定回答用must， 否定回答用needn’t。
4.You _____ get there by bus.
A. don’t need B. needn’t to
C. don’t need to D. need don’t to
思路點撥：need既可以用作情態動詞，又可以用作行為動詞，短語有need to do sth.和need doing sth. = need to be done。
