单元知识梳理

祈使句是表示请求、命令、建议等的句子。句子中通常不出现主语，谓语动词一律用原形。根据句子语气的强弱，句末用感叹号或句号。

一、祈使句的肯定式

1. 以行为动词原形开头，简称Do型。   e.g. Come here. 到这儿来。

2. 以动词be开头，简称Be型。        e.g. Be quiet, please. 请安静。

3. 以Let开头，简称Let型。           e.g. Let’s go! 咱们走吧!

注意：有时可在祈使句的句首或句尾加上please，使语气显得客气、有礼貌。如果在句尾加please，应该用逗号与前句隔开。

e.g. Go this way, please. 请这边走。

二、祈使句的否定式

1. Do型和Be型的否定式是在句首加don’t。

e.g. Don’t sit here. 不要坐在这儿。

   Don’t be late. 别迟到。

2. 以let开头的祈使句，其否定式有两种：一种是直接在句首加don’t，另一种是

“let + 宾语 + not +动词原形+ (其他)”。

e.g. Don’t let him go. 不要让他走。Let’s not go there. 咱们别去那儿。

注意“No+名词/动词-ing形式”表示禁止或规劝，常用于公共场所。

e.g. No photos!禁止拍照！     No smoking！禁止吸烟！

本单元以招聘信息为话题。认真学习并朗读以下范文，划出好词好句。

Dear Dr. Know,

It isn't fair. Our teachers are too strict（严格）with us. We have to get up early and come to school on time. We can't be late for class. We can't do other things in class. We have to listen to the teachers carefully and be ready for any surprising questions.

We have to do our homework even on weekends. We have to hand in the exercise books on school days.

We can't play ball games after class, even after school, because our parents and teachers think it's bad for our study. We can't play computer games while other students can. We can't watch TV because they think it's dangerous. We can't do the things we want to do because they don't want us to do. They only like us to do anything they want us to do.

We never have any fun. What should we do? What do you think we will be if things go on like that?
