英语祈使句详解
英语祈使句详解1. 祈使句的概念表示请求、命令、建议、祝愿、邀请或要求的句子叫祈使句;用于祈使句句首的动词总是用原形,不能用其他形式;如:Shut the door 把门关上Have a cup of coffee 喝杯咖啡吧Let them go by train. 叫他们坐火车去吧;祈使句的主语通常为第二人称you,但一般都被省略,只有在特殊的情况下才把主语you补充出来;如:You be quiet 你安静You go and tell him, Chris. 克立斯,你去告诉他;You wait here for a moment. 你在这儿等一会儿;有时祈使句的主语也可以是everybody, somebody, anybody, nobo dy等不定代词;如:Stand up, everybody 全体起立Nobody move. 任何人都不许动;2. 祈使句表示强调为了加强祈使句的语气,我们通常是在祈使句的动词原形前加上助动词do,此时通常译为“一定”“务必”等;如:Do be careful. 务必要小心;Do have some more tea. 一定再喝点茶;Do let me go. 一定让我去;副词never和always有时可用于祈使句句首,表示强调;如:Never do that again. 再不要这样做了;Always look in the mirror before starting to drive. 一定要先看看反光镜再开车;3. 祈使句的否定式构成祈使句否定式的方法很简单,那就是在动词原形前加don’t——不管祈使句所用的动词为什么性质动词,情况都是一样;如:Open the window. 把窗户打开;→Don’t open the window. 别把窗户打开;Come next Monday. 下周星期一来;→Don’t come next Monday. 下周星期一别来;对于以let us或let’s开头的祈使句,其否定式通常是在不定式之前放一个not;如:Let’s tell him the truth. 我们把实情告诉他吧;→Let’s not tell him the truth. 我们不要把实情告诉他;但在日常口语中,我们也可以把don’t放在let’s之前;如:Let’s don’t te ll him the truth. 我们不要把实情告诉他4. 祈使句与连用please为了使祈使句的语气变得委婉,我们可以在祈使句的句首或句末加上please——若加在句首,其后不用逗号;若加在句末,则通常会在plea se前加一个逗号;如:Step this way, please. 请这边走;Please type your letter. 请把你的信打出来;Open the window, please. 请把窗户打开;如果是否定祈使句,则通常将please加在don’t之前;如:Plea se don’t get angry. 请不要生气;Please don’t telephone before 8 a. m. 早8点以前请不要打电话;5. 祈使句的时间概念祈使句所表示的时间总是指将来,所以与它连用的句子原则上要用将来时态来与它呼应;如:Give me a hand, will you 帮我一个忙,好吗由于give me a hand表示隐含将来意义,所以句中的will you 不能改为do you;Try again and you will succeed. 你再试就会成功;由于句中的try again隐含将来意义,所以句中用了you will succ eed,而不是you succeed;Don’t do that again or you’ll be in trouble. 别再干那个了,否则你会有麻烦;句中的don’t do that again指的是以后不要再干那事了,由于隐含有将来意义,所所以句中用了you’ll be in trouble,而没有用you a re in trouble;6. 祈使句的省略一般说来,祈使句总是要以动词原形开头,但是,在某些特殊情况下,我们可以只用一个词或短语来表示祈使句的意义;如:Just a few please. 请给几个就行了;A little more slowly please. 再慢一点;A pound of butter. 给我一磅黄油;Two teas and four coffees, please. 请来两杯茶和四杯咖啡;助动词 do 在祈使句中的强调用法有时可在祈使句前加上助动词do 常重读,以表示说话人想特别强调他所说的话;这样用的祈使句具有以下用法:1. 表示强调的请求;如:Do come with us. 请一定要和我们一起去;Please Do be quiet a moment 求求你们安静一会儿2. 表示委婉或客气;如:Do try this fish. 请尝尝这鱼;Do have another cup of coffee. 请再喝杯咖啡吧;3. 表示不耐烦;如:Do stop talking 别说啦4. 希望说服对方;如:Do help me with this maths problem. 务请帮我解答这道数学题;someone和nobody等用作祈使句主语有时因为语义的需要,someone, nobody, everybody 等也可用作祈使句主语;如:Nobody say a word 都不许说话Someone fetch a pail of water. 谁去打一桶水来;Someone go and see who it is. 谁去看看是什么人来了;Somebody answer the phone please. 请来个人接电话;Everybody sit down and let’s have a drink. 大家坐下来喝一杯吧有时用作祈使句主语的还可以特定的某人;如:The boy in the corner come here. 在角落的那个男孩来这里吧这类句子有时也可以是否定的;如:Don’t anybody get out of here. 大家都别出去祈使句何时可以保留主语you祈使句的主语通常为第二人称you,但一般都被省略的;但以下两种情况可以保留主语you:第1情况为了有所区分,祈使句可以保留主语 you;如:You go on; I’ll wait. 你们先走,我等着;You wait here for a moment. 你在这儿等一会儿;You girls stand in the front row. 你们女孩子站在前排;You play Romeo and you play Juliet. 你演罗蜜欧,你演朱丽叶;You wait here, Jim, and Mary, you wait there. 你等在这儿,吉姆;玛丽,你等在那儿;第2种情况为了表示生气或有意表示无礼,祈使句可以保留主语 you;如:You be quiet 你给我安静You stop talking. 你给住嘴;You get out of here 你给我滚出去;You do it right away. 你给我马上就去做;let us 与let’slet us 的 us 既可指说话者一方此时表示请求或命令,也可以指说话者和听话者双方此时表示建议或劝诱,此用法在语体上较正式;而let’s 中的’s=us 则只能指说话者和听话者双方表示建议或劝诱,不能指说话者一方即不能用来表示命令或请求;比较:让我们告诉你我们在博物馆里看到的情况;误:Let’s tell you what we saw in the museum.正:Let us tell you what we saw in the museum.我们做朋友吧;正:Let’s be friends.较口语化正:Let us be friends.较正式在反意问句中,表示请求或命令时,用 will you;表示建议或劝诱时,用 shall we;如:我们一起去游泳好吗正:Let’s go swimming together, shall we 较口语化正:Let us go swimming together, shall we 较正式让我们跟你一起去好吗正:Let us go with you, will you误:Let’s go with you, will you shall welet’s 的否定式可以是let’s not, don’t let’s;如:Let’s not hurry. / Don’t let’s hurry. 我们不要太急;祈使句的动词可以是被动的吗有时可以,但比较少见;如:Don’t be fooled by his appearance. 不要为他的外表所欺骗了;Don’t be taken in by his promises. 别被他的诺言所欺骗;Don’t be stampeded into buying the house. 不要一时冲动买下这所房子;有时don’t 后接的“be+过去分词”不是被动式,而是系表结构;如:Don’t be discouraged. 不要气馁;祈使句备考注意1.祈使句主要用于提出请求,发出邀请,给予指示、忠告或警告,也可发出命令等;2.祈使句的特点是:一般不出现主语you,但有时为了指明向谁请求或命令,也可以说出主语;谓语动词一律用原形;否定式一律在动词前面加don’t;如:Come this way, madam. 这边走,夫人;Don’t lose the key. 别把钥匙丢了;Someone fetch a pail of water. 谁去打一桶水来;3.有关祈使句最可能涉及的考点是:祈使句带主语以及“祈使句+and / then / or+陈述句”这一句型祈使句表示条件;另外,祈使句与反意疑问句一起考查也是高考一大特点;如:Let’s phone her now, shall we 我们现在就给她打电话,好吗You girls stand in the front row, will you 你们女孩子站在前排,好吗Work hard, and you’ll pass the exam. 努力点,你会通过考试的;请做以下试题:1 Jim, you go there to help him, _______A. do youB. will youC. are youD. have you答案选B;句首的呼语 Jim 清楚地表明这一个祈使句,只是其前带了主语而已;2 ________ me back my money, or I’ll ring the police.A. GivingB. GivenC. GiveD. To give答案选C;填空处为祈使句谓语,故用动词原形;学习祈使句的几个基本要点一、祈使句的概念和一般形式表示请求、命令等的句子叫祈使句;它的主语是听话人you ,一般不需要说出来;通常以动词原形开头;祈使句末尾用惊叹号或句号,句子用降调;如:Open the door, please. 请把门打开;Be quiet, boys. 孩子们,安静点;Hurry up快点跟上;但有时为了指明向谁请求或发出命袋子令,也可说出主语来;如:Alice, you close your book. 艾丽期,请你把书关上;二、祈使句的否定式祈使句的否定式是在动词原形前加don’t;如:Don’t be late again. 不要再迟到了;Please don’t forget to take your medicine. 请不要忘记吃药;Don’t let’s quarrel about it. =Let’s not quarrel about it.我们不要为此事争吵了;三、祈使句的强调式Do be on time. 务必准时;Do come early. 务必早点来;四、区分let’s与let us /sb.Please let him in. 请让他进去;—Let’s go swimming, shall we我们去游泳,好吗—No, let’s not. /Yes, let’s. 不要去了;/我们去吧;—Let us go swimming, will you请你让我们去游泳,好吗—No, you’d better not. 你们最好别去;不要混淆祈使句与非谓语动词有这样一道语法考题,该用动词原形还是用非谓语动词_________ the road round to the right and you’ll find his h ouse.A. FollowB. FollowingC. To followD. Followed分析此题容易误选B或C,许多同学一看选项就想当然地认为,选现在分词表示时间或伴随,选不定式表目的;此题的关键是要注意句中的连词an d,它表明整个句子是一个并列句,即 and 前后应各是一个独立的句子,而不应是一个非谓语形式的短语,所以此题的正确答案应选A,即 and 前是一个祈使句;比较以下两题:1 _________ the road round to the right, she found his house.A. FollowB. FollowingC. To followD. Followed分析此题应选B,现在分词短语表时间;2 _________ the road round to the right, the blind man askeda boy to guide him.A. FollowB. FollowingC. To followD. Followed分析此题应选C,不定式短语表目的;注意以下各题均应选A,均因为句中的并列连词 and填空句为祈使句:1 _________ the milk and set a good example to the other chi ldren.A. DrinkB. To drinkC. DrinkingD.

用于祈使句句首的动词总是用原形,不能用其他形式。
如:Shut the door! 把门关上!Have a cup of coffee! 喝杯咖啡吧!Let them go by train. 叫他们坐火车去吧。
助动词 do在祈使句中的强调用法有时可在祈使句前加上助动词do (常重读),以表示说话人想特别强调他所说的话。
这样用的祈使句具有以下用法:1. 表示强调的请求。
如:Do come with us. 请一定要和我们一起去。
Please! Do be quiet a moment! 求求你们! 安静一会儿!2. 表示委婉或客气。
如:Do try this fish. 请尝尝这鱼。
Do have another cup of coffee. 请再喝杯咖啡吧。
3. 表示不耐烦。
如:Do stop talking! 别说啦!4. 希望说服对方。
如:Do help me with this maths problem. 务请帮我解答这道数学题。
someone和 nobody等用作祈使句主语有时因为语义的需要,someone, nobody, everybody 等也可用作祈使句主语。
如:Nobody say a word! 都不许说话!Someone fetch a pail of water. 谁去打一桶水来。
Someone go and see who it is. 谁去看看是什么人来了。
Somebody answer the phone please. 请来个人接电话。
Everybody sit down and let’s have a drink. 大家坐下来喝一杯吧!有时用作祈使句主语的还可以特定的某人。

英语祈使句详解
英语祈使句详解英语祈使句详解1.祈使句的概念表示请求、命令、建议、祝愿、邀请或要求的句子叫祈使句。
用于祈使句句首的动词总是用原形,不能用其他形式。
如:Shut the door! 把门关上! Have a cup of coffee! 喝杯咖啡吧!Let them go by train. 叫他们坐火车去吧。
祈使句的主语通常为第二人称(you),但一般都被省略,只有在特殊的情况下才把主语(you)补充出来。
如:You be quiet! 你安静! You go and tell him, Chris. 克立斯,你去告诉他。
You wait here for a moment. 你在这儿等一会儿。
有时祈使句的主语也可以是everybody, somebody, anybody, nobody等不定代词。
如:Stand up, everybody! 全体起立!Nobody move. 任何人都不许动。
2.祈使句表示强调为了加强祈使句的语气,我们通常是在祈使句的动词原形前加上助动词do,此时通常译为“一定”“务必”等。
如:Do be careful. 务必要小心。
Do let me go. 一定让我去。
副词never和always有时可用于祈使句句首,表示强调。
如:Never do that again. 再不要这样做了。
Always look in the mirror before starting to drive. 一定要先看看反光镜再开车。
3.祈使句的否定式构成祈使句否定式的方法很简单,那就是在动词原形前加don’t——不管祈使句所用的动词为什么性质动词,情况都是一样。
如:Open the window. 把窗户打开。
→Don’t open the window. 别把窗户打开。
Come next Monday. 下周星期一来。
对于以let us或let’s开头的祈使句,其否定式通常是在不定式之前放一个not。
