2、踩草地！Put the boxes in the small room.把那些盒子放到那个小房间里。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 + adj.Be careful! = Look out! = Take care! 小心 / 当心！（3）Lets + 动词原形Lets go to school together. 咱们一起上学去吧。2. 否定的祈使句(1) Dont + 动词原形 Never + 动词原形Dont stand up. 别站起来。Dont be careless. 别粗心。Don

3、t let them play with fire. 别让他们玩火。(2) Lets ( let sb. ) + not + 动词原形Lets 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.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wont you。Please open the door, will/ wont 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。Dont be late again, will

4、 you? 别再迟到了，行不行？(3) 以lets开头的祈使句反意疑问句反问部分用shall we。Lets turn on the TV, shall we? 我们把电视打开，好吗？ 只有以lets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wont you.如：Let us stay here, will/ wont you? 请（你）让我们留在这好吗？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！5.祈使句的回答祈使句的动作通常是

5、表示将来发生的动作，所以回答祈使句时，一般用will或wont。在回答具有否定意义的祈使句时，要注意两点：一是形式一致，即Yes与will保持一致；No与wont保持一致。二是意思相反，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。例如：- Dont go out, please. Its 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。6.祈使句与陈述句的并列使用祈使句后接陈述句时，须用连接词

6、连接。如果祈使句与陈述句表示的是一种顺承关系时，要用并列连词and来连接；如果祈使句与陈述句存在一种否定条件关系时，要用并列连词or来连接。例如：Leave it with me and I will see what I can do.把它留给我吧，我想想有没有办法。Hurry up, or well be late.快点，否则我们要迟到了。七.祈使句与条件状语从句的连用祈使句与条件状语从句连用时，条件状语从句可置于祈使句前或后。例如：Tell him to make a phone call to me if he comes here tomorrow.如果他明天来这儿的话，叫他给我来个

7、电话。八.祈使句的强调形式祈使句的强调形式通常在肯定祈使句式前加上助动词Do(Do在句中无意义)。例如：Do shut up! 快住口！九.特殊形式的祈使句在英语中，有些祈使句不是以动词原形来引起一个祈使句，而是以一个名词短语来充当，且后接一个带有并列连接词的分句。实际上，这个充当祈使句的名词短语相当于一个条件状语从句。例如：More water and the young trees couldnt have died. If you had given them more water, the young trees couldnt have died.如果你给那些小树多浇点水，他们就不会

8、死了。十.运用祈使句的误区祈使句往往容易与不定式、分词或条件状语从句相混淆。在平时的练习或测试中，如果稍不留神，就会出错。因此，要认真审题，认真分析句子结构，并根据上下文语境，作出正确判断。例如：_ your composition carefully, some spelling mistakes can be avoided.A. Having checked B. Check C. If you check D. To check析：如果空白处选填B(Check)项，则视为祈使句，但后一分句前没有并列连接词and连接；如选A或D项(分词或不定式)，句中逻辑主语some spelling

9、mistakes又不能执行这个动作，故均不符合句子结构。因此，只有C项(条件状语从句)符合句子结构及句意。祈使句考题集锦（1）一、单项选择1. The TV is too loud. Please_.A. turn it down B. to turn it down C. turn down it D. to turn down it2. _ late again, Bill!A.
