21、e动词引起的肯定祈使句前加Don,t,构成“ Dont be+其他成分（形容词、名词或介词短语等）”。Dont be careless.不要粗心。注意：在这种句型中be不能省略；否认副词not不可置于be之后。. Let引起的祈使句的否认形式有两种：（l）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Dont也可在Let后宾格的名词或代词后面加not。（2）如果以Lets开头的祈使句， 必须在Lefs后加not。Dont let me go with her tomorrow. =Let me not go with her tomorrow.不要让我明天跟她起

22、去。Lets not tell her the truth whenever we meet her.无论什么时候我们碰到她，都不要告诉她真相。.在公共场合的提示语中，否认祈使句常用” No+名词/V-ing形式”结构，表示“禁止做某事NO PHOTOS!禁止拍照！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局部。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wonyou。Be sure to write to us, will you?你一定要给我们写信，好吗？Come to have dinne

23、r with us this evening, wont you?今晚来和我们一起吃饭，好吗？.祈使句为否认句式，其反意疑问句通常只用will you。Don,t smoke in the meeting room, will you?不要在会议室抽烟，好吗？. Let开头的祈使句构成反意疑问句时，除Lefs用shall we外，其他均用will you。Let the boy go first, will you?让个那男孩先走，好吗？五、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wonk在回答具有否认 意义的祈使句时，要注意两点：一是“形式一致，即

24、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。一Dont go out, please. Ifs raining heavily outside.请不要出去。外面雨下得很大。一Yes, I will. I have to meet my brother at the airport.不行，我得去机场接我弟弟。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认条件关系时，要用

25、并列连词or来连接。Leave it with me and I will see what I can do.把它留给我吧，我想想有没有方法。Hurry up, or well be lat已快点，否那么我们要迟到了。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。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 。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）。Do shut up!快住口！九、特

26、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。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的话，它们就不会死了。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

27、，认真分析句子结构，并根据上下文语境，作出正确判断。your composition carefully, some spelling mistakes can be avoided.A. Having checkedB. CheckC. If you checkD. To check反意疑问句高考对疑问句的考查主要是对反义疑问句的考查。反义疑问句也叫附加疑问句，指的是在陈述句后面附加一个简短的一般疑问句，用于对陈述句所说的 事实或观点提出疑问或表示证实。陈述局部与附加局部的动词时态和动词性质应保持一致，但是肯定和否 定形式却彼此相反，即陈述局部为肯定式时，疑问句局部用否认式；陈述局部为否认式

28、时，附加局部用肯 定式。反义疑问句主要分以下各种情况：反意疑问句由两局部构成：前一局部用陈述句形式，后一局部是一个附加在前一局部上的简短问句。 陈述局部用肯定形式时，附加问句局部用否认形式，反之亦然。附加问句局部的动词形式及主语由陈述句 决定，而且主语必须是代词。.陈述局部的主语是名词时，附加问句的主语用相应的人称代词。Your parents had a long talk with you last night, didnt they?.陈述局部主语是表示人的不定代词时，反意疑问句的主语侧重全部用they,侧重个体用he。No one was there that day, was he/

29、were they?.陈述局部主语是表示物的不定代词时，反意疑问句的主语用it。Everything that he says is true, isnt it?.陈述局部的主语是one时，反意疑问句的主语在正式的场合用one,在非正式场合用you。One should be honest, shouldnt one/you?.陈述局部主语是指示代词时，反意疑问句的主语要用it或they。This is your car, isnt it?Those are grapes, arent they?.陈述局部是there be结构时，反意疑问句仍用thereoThere was a hospit

30、al here, wasnt there?.陈述局部有表示推测的情态动词must时，反意疑问句的动词与must后的动词一致。They must be sleeping then, werent they?must后接完成式，假设表示对过去情况的推测，附加问句中动词用didn,t；假设表示对已完成情况的推测，用haven或hasnt。.陈述局部含有否认词时，反意疑问句用肯定式。He is never late for school, is he?They seldom clean the room, do they?误a警示常见的否认词有 no, never, nothing, nowhere,

31、 rarely, hardly, seldom, few, little 等；假设陈述局部有 带否认意义词缀的派生词，如dislike, useless, unfair等，后面的附加问句仍用否认式。.陈述局部是祈使句时，反意疑问句用will you或wont you。Look at the blackboard, will/wont you?Dont make any noise, will you?误a警示以Let1开头的祈使句，反意疑问句用shall we；以Let us/me开头的祈使句，反意疑问句用will you；陈 述局部是否认的祈使句，反意疑问句用will you或can you

32、都可以。.陈述局部是并列句时，反意疑问句与邻近的分句一致。She works hard and she is the best one in her factory, isnt she?.陈述局部是复合句时，反意疑问句与主句一致。When the teacher speaks in class, we have to keep quiet, dont we?.陈述局部是否认转移句式时，反意疑问句与从句一致，且用肯定形式。I dont think he will come, will he?误饺i警示在回答反意疑问句时，不管其陈述句局部是肯定的还是否认的，如果事实是肯定的，回 答用“yes+肯定

33、的简略句”；如果事实是否认的，回答用”no+否认的简略句”，形式要一致。陈述局部 是否认形式时，答语中的yes译成“不”，no译成“是“。They havent been told the truth, have they?Yes, they have. / No, they haventLets take a walk after supper, shall we?晚饭后我们去散步，好吗？经典好题l.We forgot to bring our tickets, but please let us enter,?A. do youB. can weC. will youD. shall we
