英语祈使句讲法及练习和答案

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。

祈使句一.祈使句的句式特征祈使句常常是表达说话人对对方的劝告、叮嘱、请求或命令等。

因此,祈使句中一般没有主语,但根据其句意,实际上是省略了主语you。

祈使句句末用感叹号或句号,朗读时,常用降调。

在表达请求或劝告时,在祈使句前或句末可加上please,以使句子的语气更加缓和或客气。

祈使句一般没有时态的变化,也不能与情态动词连用。

例如:Keep off the grass!勿踩草地!Put the boxes in the small room.把那些盒子放到那个小房间里。

二.祈使句的肯定句式祈使句的肯定句式一般分为以下三种类型:1.行为动词原形+其它成分。

例如:Make sentences after the model.根据例句造句。

Have a good time. 愿你玩得痛快。

2. Be动词+其它成分(形容词、名词或介词短语等)。

例如:Be careful when crossing the street.过马路时要小心。

3.Let+宾语+动词原形+其它成分。

例如:Let him go back now.让他现在回去吧。

Let me have a rest. 让我休息一会儿吧。

三.祈使句的否定句式祈使句的否定句式,通常情况下在句首加上Don’t或Never,一般分为以下四种类型:1.在祈使句的肯定句式前加Don’t,构成『Don’t+行为动词原形+其它成分』。

例如:Don’t say that again!别再那样说了!2.在Be动词引起的肯定祈使句前加Don’t,构成『Don’t be+其它成分(形容词、名词或介词短语等)』。

注意:在这种句型中be不能省略;否定副词not不可置于be之后。

例如:Don’t be careless.不要粗心。

3. Let引起的祈使句的否定形式有两种:(1)Let开头的祈使句,如果后面跟第一、第三人称名词或代词的宾格,可在Let前加Don’t,也可在Let后宾格的名词或代词后面加not。

(2)如果以Let’s开头的祈使句,必须在Let’s后加not。

例如:Don’t let me go with her tomorrow.=Let me not go with her tomorrow.不要让我明天跟她一起去。

Let’s not tell her th e truth whenever we meet her.无论什么时候我们碰到她,都不要告诉她真相。

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!No Entry禁止入内!No Passing禁止通行! No Smoking禁止吸烟!四.祈使句的反意问句祈使句的反意疑问句须按其句子结构及讲话人的语气来决定其疑问部分。

通常有以下三种形式:祈使句为肯定句式,其反意疑问句表示请求时,通常用will you;表示邀请、劝说时,用won’ t you。

例如:Be sure to write to us, will you?你一定要给我们写信,好吗?Come to have dinner with us this evening, won’t you?今晚来和我们一起吃饭,好吗?2.祈使句为否定句式,其反意疑问句通常只用will you。

例如:Don’t smoke in the meeting room, will you?不要在会议室抽烟,好吗?3. Let开头的祈使句构成反意疑问句时,除Let’s用shall we外,其它均用will you。

例如:Let the boy go first, will you?让个那男孩先走,好吗?Let’s take a walk after supper, shall we?晚饭后我们去散步,好吗?五.祈使句的应答句祈使句的动作是未发生的动作,常用I will.来回答其肯定式,表示愿意接受请求或命令,用I won't.来回答其否定式。

另外,常用All right. / OK. / Yes, let's... / A good idea.等来回答Let's...句式,表示接受建议;用You may. / You can.等来回答Let us...句式,表示允许或同意。

六.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。

考查"祈使句(或名词词组)+ and(或or)+ 简单句"这一固定句型。

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 we’ll 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!Do be careful. 务请小心。

Do come on time. 务必请准时来。

九.运用祈使句的误区1、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 checkedB. CheckC. If you checkD. T o 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 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。

2. 考查祈使句型与非谓语动词作状语的辨别能力注意标点符号(如破折号)的功能,牢记常见祈使句的结构,排除非谓语动词的干扰(非谓语动词提前作状语,常用逗号与后面分开,表示时间、原因、条件、目的等)。

[原题再现] 答案: AI've never seen anyone run so fast - ________David go.A. just watchB. just to watchC. just watchingD. just having watched【指点迷津】◆肯定结构的祈使句常以谓语动词原形开头。

◆否定结构的祈使句常在谓语动词原形前加上Never或Don’t。

◆以let引导的祈使句结构,有以下几种情况:1.“Let me+动词原形”,意为“请让我……”。

2.“Let’s +动词原形”,意为“让我们……”,表示建议或请求。

3.“Let+第三人称作宾语+动词原形”,意为“让……”,表示愿望、命令或允许。

◆在开头的动词原形前加Do(务必)或Always(永远),表示强调。

如:Do write to us often! 务必经常给我们写信。
