新疆乌鲁木齐市第七十中学2020高中英语 Module 2 The Fourth Period导学案 外研版必修4(无答案)

Module 4 Traffic Jam
The Fourth Period Grammar
1. 基本句型 1) Do 型（以行为动词原形开头） e.g. Get out! Stand up!
2) Be 型
e.g. Be quiet! Be careful next time.
3) Let+宾语+do 型
e.g. Let him in, please! Le t’s listen to the music.
2. 祈使句的否定式：Don ’t/Never+动词原形
Don ’t make any noise!
Never do that again!
注意：Let ’s 型祈使句，其否定式也可用Let ’s not 表达。

例如：
Let ’s not play any more!
Let ’s not waste our time!
3. 加强祈使句语气的方式：在谓语前加do/you 。

Do write back when you receive his letter
Tom, you clean the classroom.
4. 祈使句的反义疑问句
1）若陈述部分为祈使句，反义疑问句通常用will you, won ’t you, would you 等。

e.g. Mail the letter today, will you?
表示命令、请求、建议、劝告或号召的句子
叫做祈使句。

祈使句的主语为you ，通常省略，
谓语动词使用原形，句末用感叹号或句号。

Try to be back by two, won’t you?
If you want help, let me know, would you?
【注】若陈述部分为否定式，则反义疑问句部分只用will you.
e.g. Don’t forget to post the letter, will you?
有时根据语境的需要，反义疑问句也可以用can you, can’t you等
e.g. Give me some cig arettes, can you?
Walk faster, can’t you?
一般说来，用will you, won’t you, would you等构成的反义疑问句语气较委婉。

e.g. Be quiet, will you? 请安静，好吗？
Be quiet, can’t you? 你不能安静点儿吗？
2) 以let’s开头的祈使句，其附加疑问句一般用“shall we”, 而以let us 开头的祈使句，其附加疑问句则用“will you”。

因为let’s中的us 包含听话者（即被请求者），而let us 中的us 不包含听话者在内。

e.g. Le t’s practice our spoken English, shall we?
Let us play football this afte rnoon, will you?
5.祈使句表祝愿
Success to you!
Wish you a good journey.
May you have a happy life.
Allow me to propose a toast to our friendship.
