英语祈使句讲法与练习和答案
祈使句一、祈使句（ Imperative Sentence）定义：用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句.祈使句因对象（即主语）是第二人称，所以通常都省略。
祈使句的动词都为一般现在时。
例： Go and wash your hands.（去洗你的手。
——命令）Be quiet, please（. Please be quiet）. （请安静。
——请求）Be kind to our sister. （对姊妹要和善。
——劝告）Watch your steps.（走路小心。
——警告）Look out！Danger！（小心！危险！——强烈警告，已如感叹句）No parking. （禁止停车。
——禁止）二、祈使句的否定形式祈使句的否定形式是在整个结构之前加don’t 或 never。
如：Don’t you be nervous!你不要紧张 !以 let 为引导词的祈使句的否定形式通常是在Let’s 或 Let us／me 后加 not。
如：Let’s not waste our time arguing about it!咱们别浪费时间争论这事了! Let’s not say anything about it! 这事咱们谁也别说 !但英式英语也用这样的表达：Don’t let’s say anything about it.三、祈使句的反意疑问句1．祈使句的反意疑问部分为肯定形式，要用will 。
如：Pass me the book，will you?2．Let’s 表示第一人称的祈使句，反意疑问句为“Shall we?”。
如：Let’s go for a walk，shall we?Let’s forget it，shall we?3．Let me 和 Let us 表示第二人称的祈使句，反意疑问句为“will you?”。
如：Let us go for a walk， will you?4．其它行为动词引起的祈使句，无论其陈述部分是否定还是肯定的祈使句，多用“ will you? ”，表一种客气的语气。

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Stand up, please. = Please stand up. 请起立。
（2）Be + n./adj.Be a good boy! 要做一个好孩子! Be careful! = Look out! = Take care! 小心 / 当心！（3）Let + 宾语 + 动词原形 + 其它成分Let me help you. 让我来帮你。
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型的否定式有两种:“Don't + let + 宾语 + 动词原形 + 其它成分”和“Let + 宾语+ not + 动词原形 + 其它成分”。
Don't let him go. / Let him not go. 别让他走。
Let them not play with fire. 别让他们玩火。
（3）no开头,用来表示禁止性的祈使句。
No smoking! 禁止吸烟!No fishing! 禁止钓鱼!3. 祈使句的强调形式，通常在肯定祈使句式前加上助动词Do。
例如：Do shut up! 快住口！4. 祈使句的回答祈使句的动作通常是表示将来发生的动作，所以回答祈使句时，一般用will或won’t。
在回答具有否定意义的祈使句时，要注意两点：1)形式一致(即Yes与will保持一致；No与won’t保持一致)2) 意思相反(即Yes是“不”的意思；No是“是”的意思)。
在回答时，要注意分析上下文语境中所提供的条件。
如：--- Don’t go out, please. It’s raining heavily outside. 请不要出去。
外面雨下得很大。
---- Yes, I will. I have to meet my brother at the airport. 不行，我得去机场接我弟弟。
5. 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.如：Let us stay here, will/ won't you? 请（你）让我们留在这好吗？一. 用括号内所给动词的适当形式填空。
