情态动词
一、定义：
情态动词没有人称和数的变化，但有一定的意义;不能单独使用，必须与动词原形一起构成谓语; 表示说话者的态度、情感以及对某一行为或状态的看法或态度。
本单元我们主要接触的情态动词有：
1. can
(1)表示能力，意为“能，会”。
Can you play tennis
(2)表示提建议或请求。
Can you pass me that book
(3)表示“许可，可以”，常用于口语中。否定式用can’t。表示表示否定推测“一定不，不可能”，常用can’t。
You can use my bike.
I saw him playing football just now. He can’t
be in the classroom.
二、情态动词的用法归纳
—Can I borrow your ruler, please
—Yes, you ______. But you must return it to me before
lunchtime.
A. have B. can C. must D. used to
【解析】考查情态动词。答句意为“是的，你可以，但你必须在午饭之前归还给我”，所以选择B。
The man ______ be my English teacher. He has gone to Canada.
A. might B. must C. can’t
【解析】考查情态动词的用法。must表肯定的推测，意为“一定”，可能性较大，might表示肯定推测，“可能”，可能小较小，can’t表示否定推测，意为“不可能”。根据句意：那个人不可能是我的英语老师，他去加拿大了。故选C。
B
C
2. must
(1)表示“必须”，强调主观意愿或客观要求。
I must go now.

(3)mustn’t意为“不要”，表示禁止或不允许。
