知识点
1
考向一

“Don't＋动词原形”是祈使句的否定
形式，意为“不要……；禁止……”，相当于
“You mustn't＋动词原形”。
eg：Don't be late for class next time.
下次上课不要迟到了。
Don't play football in the street.
不要在街上踢足球。
考向二
arrive late for与be late for的区别
arrive late for
都表示
“迟到” 侧重到达时间晚 Don't arrive late for the meeting next time.下次开会别迟到了。
侧重于状态 She is late for work every day. 她每天上班都迟到。
be late for
典例
Don't be late ________class! We must be on time. (成都)
A. for　　　 B. to　　　C. in
A

You must be on time.你一定要准时。

知识点

must为情态动词，意为“必须，一定”。情态动词不能单独作谓语动词，必须和动词原形一起构成谓语。
eg: You must read a book before you watch TV.
在看电视前你必须读书。
(1)must modal verb 必须
The passengers ________ show their ID cards before getting on the plane.(株洲)
A．might　　　B．must　　　C．could
典例
B

【点拨】考查情态动词。might可能；must必须；could能，
可以。句意：乘客在登机前必须出示他们的身份证。　
考向二
must用于否定句时，mustn't意为“不允许，禁止”，而不表示“不必”。
eg: You mustn't be late for school.
你千万不要上学迟到。
典例
Children ________ sit in the front(前面) seat of a car. It's too dangerous(危险).
A．need　B．needn't　C．must　D．mustn't
D

【点拨】 考查情态动词。mustn't 表“禁止”。句意：
孩子禁止坐在小汽车的前座上，那太危险了。　
考向三
以must开头的一般疑问句，若作否定回答，
可以用needn't或don't have to，不用mustn't。
eg: —Must I clean all the rooms?
我必须打扫所有的房间吗？
—No，you needn’t/don’t have to. 不，你不必。
典例
—Must I hand in(上交) my homework now,
Mr. Smith?
—No, you ________. (北京)
A．can't B．shouldn't
C．wouldn't D．needn't
D
(2)on time意为“准时；按时”，指在规定的时
刻发生。
eg: We can't finish the work on time without his help.
没有他的帮忙，我们不能按时完成工作。
考向
辨析on time与in time
on time 准时(在规定的时间之内) 表示动作在规定时间内或比规定时间提前发生。
in time 及时(恰在时间点上) 强调与某个时刻一致。

魔法记忆
She didn't catch the bus in time，so she couldn't arrive there on time.
她没有及时赶上公共汽车，因此她不能准时到那里。
典例
The teachers hope all of us can hand ________ our homework ________ time every day. (黄石)
A．up; in B．out; on
C．on; in D．in; on
D

【点拨】考查介词的用法。hand in 上交；on time 按时；
in time 及时。句意：老师希望我们所有人每天都能按时
交作业。故选D。

Don't listen to music in class.
不要在课堂上听音乐。
考向一

①listen to music意为“听音乐”，其中listen
为不及物动词，其后接宾语时，要加介词to。
eg: Listen！The girl is singing.
听！那个女孩正在唱歌。
Listen to the teacher carefully, please.
请认真听老师讲课。
②辨析listen和hear
listen 不及物动词 后接宾语时，要加介词to，侧重于“听”的动作
This girl likes to listen to the radio.这个女孩喜欢听收音机。
hear 及物动词
强调“听”的
结果
Can you hear anything？
你能听到什么吗？
典例
We all ________ the man carefully(仔细), but we can't ________what he says.
A．listen to; listen to　　　B．listen to; hear
C．hear; listen to D．hear; hear
B

【点拨】 listen to“听”，强调动作；hear“听到”，强调
结果。句意：我们都在仔细听那个人说，但是没听见他说
什么。所以选B。
①in class是固定短语，意为“在课上；上课时”，
after class意为“在课下；下课后”。
②辨析in class和in the class
in class 在课上；上课时 Do you listen to your teacher carefully in class？你在课上认真听老师讲课吗？

这个班有40名学生。
