1、 易错精讲
1.must和can
【用法】①must和can都是情态动词,后面跟动词原形,情态动词没有人称和数的变化。常用的情态动词还有:should,may,could等。
②can的基本用法:
a.表示“能,会”,指个人能力或客观上有此可能。如:
He can speak English. 他会讲英语。
b.表示“可能”,指某件事情发生的可能性。如:
Mary can't be in the classroom. 玛丽不可能在教室里。
c.表示“可以”,指许可或请求做某事。如:
Can I have a cup of coffee, please? 请问我可以喝一杯咖啡吗?
③must和 mustn't
a.must表示“必须”。如:
You must do your homework now.你必须现在做作。
b.must否定形式:mustn't,表示“不要、不能、禁止”的意思,语气较强烈。如:We mustn't play on the road.我们千万不能在马路上玩耍。
2.含有look的短语
【用法】look for寻找 look at看 look out for小心,留神
look out小心,当心 look out of朝……外看 look after照顾,照看
3. other people/ the other people区分
【用法】①other people指别人(不是特指)。如:

②the other people特指其余的人。如:

二、写作园地
假设你是班长,请以“Classroom rules"为题,用must和mustn't来为你的班级制订一些规则。要求:语句通顺,不少于6句话。
【点拨】这是一篇联系实际生活的小练笔,同学们在写之前,可以先想一想班级有哪些允许做和不允许做的事情。然后使用情态动词must和mustn't来写句子。
【参考范文】
Classroom rules
You must keep your desk clean and tidy.You must be quiet in the classroom. You must listen to yourteachers in class. You mustn't run in the classroom. You mustn't eat or drink in class. You mustn't play ballgames in the classroom.
