学生通过本讲学习，能够掌握本单元的重点语法，并在综合能力上有一定的拓展。
祈使句
一、祈使句指的是表示命令、请求、建议或劝告的句子。其主语you 常省略，谓语动词用原形，句
末用感叹号或句号，读降调。
二、祈使句的肯定句式一般分为以下三种类型：
1.行为动词原形＋其它成分。例如：
Make sentences after the model.根据例句造句。
2. Be 动词＋其它成分(形容词、名词或介词短语等)。例如：
Be careful when crossing the street.过马路时要小心。
3. Let＋宾语＋动词原形＋其它成分。例如：
Let him go back now.让他现在回去吧。
三.祈使句的否定句式
祈使句的否定句式，通常情况下在句首加上Don’t 或Never，一般分为以下四种类型：
1.在祈使句的肯定句式前加Do’t，构成『Don’t＋行为动词原形＋其它成分』。例如：
2
Don’t say that again!别再那样说了！
2.在Be 动词引起的肯定祈使句前加Don’t，构成『Don’t be＋其它成分(形容词、名词或介词短
语等)』。例如：Don’t be careless.不要粗心。
注意：在这种句型中be 不能省略；否定副词not 不可置于be 之后。
3. Let 引起的祈使句的否定形式有两种：
(1)Let 开头的祈使句，如果后面跟第一、第三人称名词或代词的宾格，可在Let 前加Don’t，也
可在Let 后宾格的名词或代词后面加not。
(2)如果以Let’s 开头的祈使句，必须在Let’s 后加not。例如：
Don’t let me go with her tomorrow. ＝Let me not go with her tomorrow.
不要让我明天跟她一起去。
Let’s not tell her the truth whenever we meet her.
无论什么时候我们碰到她，都不要告诉她真相。
4.在公共场合的提示语中，否定祈使句常用『No＋名词/V-ing 形式』结构，表示『禁止做某
事』。例如：
NO PHOTOS! 禁止拍照！
四.祈使句的反意问句
祈使句的反意疑问句须按其句子结构及讲话人的语气来决定其疑问部分。通常有以下三种形式：
1.祈使句为肯定句式，其反意疑问句表示请求时，通常用will you；表示邀请、劝说时，用
won」t you。例如：
Be sure to write to us, will you? 你一定要给我们写信，好吗？
Come to have dinner with us this evening, won’t you?
今晚来和我们一起吃饭，好吗？
2.祈使句为否定句式，其反意疑问句通常只用will you。例如：
3
Don’t smoke in the meeting room, will you?
不要在会议室抽烟，好吗？
3. Let 开头的祈使句构成反意疑问句时，除Let’s 用shall we 外，其它均用will you。例如：
Let the boy go first, will you? 让个那男孩先走，好吗？
Let’s take a walk after supper, shall we?
晚饭后我们去散步，好吗？
情态动词
must 和have to
情态动词
用法
例句
must
表示“ 必须，应该” 之意，语气比
should ，ought to 强烈。其否定形式
mustn’t 表示“不准，不应该，禁止”等
意
1．You must come to school on time.
2．Everybody must obey the law.
3．You mustn’t drive so fast in the street.
4．We mustn’t waste any more time.
在回答带有must 的问句时，否定回答常
用needn’t 或don’t have to ，表示“ 不
必”，而不用mustn’t
1．—Must I come back before ten?
—Yes，you must.(No, you needn’t)
表示有把握的推测，意为“一定、准是、
相必”，只用于肯定句中
1．It must be my mother.
2．You must be hungry after a walk.
3．There must be a hole in the wall.
have to
have to
“必须，不得不”，意义与must 相近。
但must 表示的是说话人的主观看法，而
have to 则往往强调客观需要。
1．The film is not interesting. I really
must go now.
2．I have to go now, because my mother
is in hospital.
must 只有一种形式，即现在式与过去式
都是一种形式，而have to 则涉及各种人
称、时态等方面的变化形式。
1．I had to work hard when I was your
age.
2 ．I will have to learn how to use a
computer.
3．In order to take the exam, we’ll have
to finish the whole book by the end of
this month .
两者的否定意义不同，mustn’t 表示“禁
止，不许”，don’t have to 表示不必。
1．You mustn’t go there.
2．You don’t have to go there.

八、阅读与表达(问答式) (101 中学初一下期中考试)
Have you ever had problems in your life and don't know how to be happy? If so, you will find the
book Being a Happy Teenager is very useful, which is written by an Australian writer Andrew Matthews.
Andrew Matthews works as a writer, cartoonist(卡通画家) and speaker. His books have been
translated into 20 languages. He has been on over 2000 radios and TV programs.
In this book, Matthews tells us how to have a happy life and answers the questions of teenagers.
There are many topics such as parents and friends, and the book says we should stop being angry and
learn to forgive(原谅). The book tells us of useful skills such as how to put what you have learned into
pictures of your mind to make your memory better. Many teenagers think that happiness comes from a
good exam marks or praise from other people. But you can still be happy when there are no such "good"
things.
Success comes from a good attitude(态度). If you learn from problems, you will have success in the
future.
Some school boys have problems such as being too tall or too short. But Matthews tells us happiness
comes from thinking about things in a positive(积极的) way.
If you are tall, people notice you and you can get a better view(视线) at the movie; if you are short,
your clothes and shoes take less room in your bedroom! This is Matthews' most important lesson: You
choose to be happy!
根据短文内容，完成下列小题。
51. Is Matthews Australian?
52. What does Matthews do?
53. Does success come from a good attitude or not?
54. How should you think about things if you are too tall or too short? (no more than 10 words)

55. What's the title of the passage?
