●情态动词 本身有一定的含义，但不能单独作谓语，后跟行为动词原形一起构成谓语，表示说话人的语态和情态。
●情态动词没有人称和数的变化。常见的情态动词有：
Grammar——情态动词
can, could, may, might, shall, should, must, need, dare, ought to, will,
would, used to
1.— Could I cross the street here
— Of course, you____.
A. could B. can C. be able to D. will
思路点拨： 此句中的could 表示委婉的语气，而不是表示过去时态。故回答时应用can，表示能够做某事。
2. Some people think trees _____ on Tree Planting Day only.
A. should be planted B. should plant C. should be planting D. be planted
思路点拨：表“义务”和“应该”时，用should。情态动词的被动语态为：情态动词+ be +done。
B
A
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
思路点拨：用must 引导的一般疑问句，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
思路点拨：need既可以用作情态动词，又可以用作行为动词，短语有need to do sth.和need doing sth. = need to be done。
C

—Good idea!
A. Would B. Shall C. Must D. Need

思路点拨：
● 情态动词must, may, might, can, could等都能表示“推测”。它们的推测程度由强到弱的顺序是：must, can, could, may, might。
●must表示有把握的推测，意为“一定是，肯定是”，只用于肯定句，表示对现在的推测。否定形式则用needn’t。而mustn’t 则表示
“禁止”。
