初中英语――祈使句
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。

1. 肯定的祈使句
（1）动词原形+其他
（为了使祈使句语气委婉些，常在句首或句尾加上please, 若把please放在句尾，其前要用逗号隔开。

）
Stand up, please. = Please stand up. 请起立。

（2）Be + adj.(形容词)
Be careful! = Look out! = Take care! 小心/ 当心！
（3）Let's + 动词原形
Let’s go to school together. 咱们一起上学去吧。

2. 否定的祈使句
(1) Don't + 动词原形
Don't stand up. 别站起来。

Don't be careless. 别粗心。

Don't let them play with fire. 别让他们玩火。

（2）Let's ( let sb ) + not + 动词原形
Let's not say anything about it. 对于这件事，咱们什么也别说。

Let them not play with fire. 别让他们玩火。

（3）No+名词、动词-ing （“禁止做某事”，常用于公共场合的提示语）No photos. 禁止拍照！No smoking！禁止吸烟！
3. 祈使句的反意疑问句
(1) 肯定祈使句的反意疑问句，反问部分用will you 或won't you。

Please open the door, will/ won’t you? 请把门打开，好吗？
(2) 否定祈使句的反意疑问句，反问部分只用will you。

Don't be late again, will you? 别再迟到了，行不行？
(3) 以let's开头的祈使句反意疑问句，反问部分用shall we。

Let's turn on the TV, shall we? 我们把电视打开，好吗？
<特别注意> 只有以let's开头的祈使句的反意疑问句的反问部分才用shall we，
而let us 开头的祈使句的反意疑问句的反问部分应为will you或won't you.
（因为let’s 包括说话人在内，而let us不包括）
如：Let us stay here, will/ won't you? 请（你）让我们留在这好吗？
