1、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

2、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 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。A

3、lways 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dont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。Dont open the window.别把窗户打开。Come next Monday. 下周星期一来。Dont come next Monday.下周星期一别来。对于以let us或lets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 t

4、ruth. 我们把实情告诉他吧。Lets 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dont放在lets之前。如：Lets dont tell 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please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, plea

5、se. 请把窗户打开。如果是否定祈使句，则通常将please加在dont之前。如：Please dont get angry. 请不要生气。Please dont 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

6、中的try again隐含将来意义，所以句中用了you will succeed，而不是you succeedo Dont do that again or youll be in trouble. 别再干那个了，否则你会有麻烦。句中的dont 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 youll be in trouble，而没有用 you are in troubleo6. 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

7、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

8、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.

9、 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 lets 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：Dont 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，

10、祈使句可以保留主语you。如：You go on; Ill 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 st

11、op 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 letslet 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lets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： Lets tell you what we saw in the museum.正： Let us tell yo

12、u what we saw in the museum.我们做朋友吧。正：Lets 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: Lets 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： Lets go with you, wil

13、l you shall we?lets 的否定式可以是 lets not, dont lets。如：Lets not hurry. / Dont lets 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：Dont be fooled by his appearance. 不要为他的外表所欺骗了。Dont be taken in by his promises. 别被他的诺言所欺骗。Dont be stampeded into buying the house. 不要一时冲动买下这所房子。有时dont后接的“be+过去分词”不是被动式，而是系表结构。如：Dont

14、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dont。如：Come this way, madam. 这边走，夫人。Dont 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

15、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：Lets 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 youll 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 you B. will you C. are you D. 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

16、而已。(2) me back my money, or Ill ring the police.A. Giving B. Given C. Give D. 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

17、：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dont。如：Dont be late again. 不要再迟到了()。Please dont forget to take your medicine. 请不要忘记吃药。Dont lets quarrel about it. (=Lets 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 lets 与 let us /sb.Please

18、let him in. 请让他进去。Lets go swimming, shall we? 我们去游泳，好吗？No, lets not. /Yes, lets. 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, youd 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 youll find his house.A.
