英语怎么把陈述句改为否定句?

一、陈述句:是用来陈述一件事情或表示一种看法,可分为肯定句和否定句两种形式。

1、谓语动词是be动词,助动词have, has, will,情态动词can等时,只要直接在这些词后面加not就构成否定形式。

eg. Lily has already read this new book. (改为否定句) Lily ______ ______ this new book ________. 2、谓语动词是行为动词而又没有助动词或情态动词时,必须在谓语动词前加助动词,一般现在时加助动词do ,第三人称单数加does,一般过去时加did,再和not构成否定结构。

必须指出的是:don't, doesn't, didn't后都用动词原形。

eg.1)Jill has lunch at school every day. (改为否定句) Jill _____ _____ lunch at school every day. 2)The children had a good time at the party. (改为否定句) The children ______ _____ a good time at the party. 3)Rose didn't drink any milk this morning.(改为肯定句) Rose ______ ______ milk this morning. 二、疑问句:是用来提出问题的句子。

A.一般疑问句:以be动词, have /has/do等助动词、can/may等情态动词开头,以yes或no来回答的问句。

它的基本结构是:Be/Have /Has/Did等助动词(包括情态动词)+主语+谓语(包括表语)+┄?回答常用简略回答。

1、谓语动词是be动词、助动词、情态动词时,只要直接把这些词置于句首,句末改成问号。

eg. There's something wrong with his bike.(改成疑问句) ______ _____ _______ wrong with his bike? 2、谓语动词是行为动词时,必须在句首加上助动词Do、Does(三单)、Did(过去式)加上这些助动词后,句子中谓语动词必须用原形。

eg. 1)Edison built a science lab himself when he was ten. (改成疑问句) ______ Edison ______ a science lab himself when he was ten? 2)Those Japanese like Chinese food.(改成疑问句) ______ those Japanese ________ Chinese food? 注意:在把肯定句改成否定句或一般疑问句的时候,要注意句中是否有already、some、something、somebody等词,如果有也必须进行改变,already要改成yet,some、something、somebody等分别改成any、anything、anybody等。

另外,在改成否定句的时候注意把too改成either,both改成neither,all改成none等.在改成一般疑问句的时候,常常把第一人称I、we改成第二人称you。

B.特殊疑问句:以疑问代词或疑问副词开头,提出疑问的句子。

它的基本结构是:特殊疑问词+一般疑问句语序。

但是如果疑问词在句子中作主语或作主语的定语,就用特殊疑问词+陈述句语序。

常用的疑问词有:what, who, whose,which,when,where,how,why等,回答时针对问句中的代词和副词来回答,不用yes或no来回答。

1)对指物名词或谓语动词提出疑问,疑问词用what ①The twins were making a kite when their mother came in. (划线提问) ______ _____ the twins _____ when their mother came in? ②Mrs Turner asked her son to buy some eggs for supper. (划线提问) _______ ______ Mrs Turner ask her son ______ _______? 2)对名词前定语提出疑问,疑问词应用which,而且必须和名词连用。

I'm going to take the shirt on the right.(划线提问) ______ _____ are you going to take? 3)对指人名词或代词提问用who,作宾语时提问用whom。

eg.Li Ping,they,his father 4)对物主代词和名词所有格提问用whose。

eg. Li Ping's coat→Whose coat my father→Whose father 5)对具体时间提出疑问,如 in the morning,last Sunday等,疑问词用when;对具体几点钟提问,疑问词应用what time。

6)对具体地点提出疑问,疑问词应用where。

The pupils are having a picnic at the foot of the hill. (划线提问) _____ _____ the pupils having a picnic? 7)对表原因的从句提问,常见的有because引导的从句,疑问词应用why。

Xiao Cheng didn't go to the farm with us because he was ill. (划线提问) _______ _____ Xiao Cheng go to the farm with us? 8)对方式或程度等提出疑问,用疑问词How。

eg. go by bike like very much 9)对数量提出疑问,疑问词为How many,要注意how many必须跟名词的复数形式。

eg. two hundred sheep→How many sheep 10)对价格提出疑问,疑问词用How much。

eg. I paid fifty yuan for the sweater. ______ ______ did you pay for the sweater? 11)对时间长度提出疑问,疑问词应用How long。

eg. I've worked in that factory for two years. (划线提问)96中考题 ______ _____ _______ you worked in that factory? 12)对时间频率,如 once a year, twice a week等提问,疑问词用How often。

13)对具体次数,如 once, twice, three times等提问,疑问词用How many times。

eg. ______ did he call you the day before yesterday?Twice. 96中考题 A.What time B.How many times C.How much D.How long 14)对in+一段时间提问,疑问词一般用How soon。

eg. Jane and her brother will finish the work in two hours. (划线提问) _____ _____ _____ Jane and her brother finish the work? 15)对距离提出疑问,疑问词用How fa...

英语怎么改否定句和一般疑问句(要详细的)

动词的分类Be动词:is,am,are,was,were助动词:do,does,did,has,have,had动词 情态动词:can,must,may,should,等实义动词:run,eat,play,like,等等.陈述句改为一般疑问句的改法:一般疑问句:以be动词、助动词、情态动词为句首,句末有问号(?)的句子.例如:Is she a doctor.她是一名医生吗?Has she got any grapes?她有些葡萄吗?(这里的has是助动词,got是有的意思.Can you fly?你会飞吗?当句子中的谓语只有实义动词,没有be动词、助动词、情态动词的时候,句子变一般疑问句时要加do、does、did其中之一.如:The fox likes grapes.句子的谓语没有be动词、助动词、情态动词,只有likes,like是实义动词,因此,句首要加助动词;又因为the fox是第三人称单数,句首的助动词就用does.句子的就变成Does the fox like grapes?注意原来likes中的s,要删除.一般疑问句主语和be动词、助动词、情态动词倒装.没有这三类词时要加助动词.如:She is a doctor.She usually goes to school at seven.Is she a doctor?Does she usually go to school at seven?记住:实义动词始终在主语的后面.注意:述句(句子后面只有句号的句子)给成一般疑问句时,一般情况下,还要把第一人称I、we、my、our改成you、your,把some变成any.如:I have got some apples.I am making my aeroplane.变成:Have you got any apples?Are you making your aeroplane?We are watching TV.变成:Are you watching TV?还要注意:如果has、have、had、do、does、did后面是名词时,has、have就不是助动词了,他们是实义动词.改一般疑问时不能提前(一般情况下,所有实义动词都不能提到主语前面),要根据时态加助动词do、does、did.如:She has breakfast everyday.Does she have breakfast everyday?否定句的改法首先要认清“否”就是“不”的意思,在英语中就是not或not的省略形式n't.否定句是在be动词、助动词、情态动词后加not或not的缩略形式n't.人称不变化.实义动词不能直接加否定词,须加助动词doesn't(第三人称单数)、don't、didn't.例如:I am English teacher.改成:I am not English teacher.She has got some apples.改成:She hasn'tgot any apples.注意:一些否定词hardly(几乎不)few(很少可数)little(很少不可数)nothing(没有)none(没有人或物)等也是否定词.含有此类否定词的句子也是否定句.am not的否定缩略形式是aren't如:Su yang often plays football.可以改成:Su yang doesn't play football .Su yang seldom plays football.Su yang never plays football.Some改成否定句一般也要改成any.

英语如何改否定句

简单地说就是在动词后面加not,有is、am、are的句子会在这些词后面加not,I am a boy.没有is、am、are的句子会在动词前加don't或者do not,I like basketball.如果有must、may、can这类的词,在这类词后面加not,I can walk.一般是根据句子的不同情况进行改动。

英语改有行为动词的句子为否定句

很多英语句子是肯定形式,但却表达否定意义,有的时候又恰恰相反。

稍不留神,就会对句子实际表达的意义产生相反的理解。

在绝大多数时候,句子的形式及其传达的意义是统一的。

然而,无论中文还是英文,都会出现由于表达习惯、语气的不同以及修辞等目的,用否定句式表达肯定含义或用肯定形式表达否定含义的情况,以加强语气或使语气更加委婉含蓄。

英语中常使用一些特殊的手段来达此目的。

理解否定形式表达肯定意义有以下两种手段: 一、词汇和短语手段。

1.cannot/couldn't或can /could +否定词(not,never,hardly,scarcely)too以及比较级等等。

I can't wait to see him.我盼望着能早点见到他。

I could not feel better.我感觉再好不过了。

You cannot overemphasize the importance of it.其重要性无论怎么强调也不过分。

2.否定词(no,not,little,nothing,none,nobody)与 but,except等连用。

It leaves nothing to be desired.这已完美无缺。

Nobody but Peter can do it well.只有彼得才能做好这件事。

二、使用一些特殊的句式。

1.否定的一般疑问句。

Don't you think we should try again?难道你不认为我们应该再试一试吗? 2.特殊疑问句。

There is a lift,but why not use the lift?既然有电梯,为什么不用呢? 3.过去时的no sooner...than句型。

No sooner had she got to Guangzhou,she called me.她一到广州就给我打了个电话。

4.too...to句型。

I'm only too glad to help you.能为您效劳,我高兴极了。

5.虚拟语气。

If I haven't lost my watch!我的表要是不丢该多好! 6.含有not+表瞬间动作的动词+ till/until短语或从句。

We can't go until Thursday.我们要到星期四才能去。

7.双重否定句。

There is no smoke without fire.无风不起浪。

理解肯定形式的否定意义借助一些词汇、短语和句型。

一、词汇和短语手段。

1.在名词及短语中,常见的有absence of(缺席,缺乏),stranger(陌生人)等。

Darkness is the absence of light.黑暗就是缺乏光亮。

2.动词及短语有escape(逃过),ignore(忽略),lost(丢失)等。

I lost my book after getting offthe bus without it.当我没带书下了公共汽车之后才发觉把书丢了。

3.形容词及短语有last(不愿意的),deaf to(不听),blind to(看不见)等。

He is the last man I want to see.我最不愿意见到他。

4.介词及短语except,instead of, but,beyond,above,past等。

It's quite beyond me.这个我理解不了。

二、常用否定句型 1.too...to...,too...for... That's too much for me.这我可受不了啦。

2.stop...... Smoking is prohibited in most theaters.在大多数戏剧院里禁止吸烟。

3.虚拟语气句。

You shouldhave done it better.你本应做得更好。

(还不够好) I could have come earlier.我本来能早点来的。

(实际上没有早来) I wish he were here now.我希望他现在能在这儿。

(实际上他不在) If I only knew!要是我知道该多好。

(实际上不知道) They would rather die than surrender.他们宁死不降。

4.用before引导的从句表示"来不及……,不等,未……先……,以防?等否定含义。

Put on more clothes before you catch cold.多穿点衣服以防感冒。

5.预先安排的事未办到或计划落空。

I had hoped to save some more money to buy a new car.我本希望多攒点钱买辆新车。

6.用比较级句型表否定。

He knows more than he lets on.这件事他了解得很多,但不肯承认。

I know better than to believe him.我才不相信他那一套呢。

英语改为否定句怎么改

句中有以下词的,直接在这些词后面加NOT:1.BE动词(am/is/are/was/were)2.情态动词(can/may/must/need/should.)3.的在其后加NOT,构成时态和语态的助动词(has/have/will/be...)如:I can swim.-------I can't swim.She will come to see me next week.-----She (或won't) come to see me next week.如果没有以上的词,则句子为一般现在时或一般过去时的肯定形式,变否定句时,先将动词变为原形,在动词前面助动词DO,并在助动词之后加否定词NOT.助动词要根据时态和人称选用相应的.一般现在时用DO/DOES,其中DOES用于第三人称单数主语,DO用于除第三人称单数之外的其它主语.DID用于一般过去时,不论人称.例如:He goes to school on weekdays.-----He to school on weekdays.We went shopping last Monday.-------We shopping last Monday.We like watching TV.------We watching TV.另外,除了NOT ,还有一些具有否定意义的词,以上是基本的,先记住这些.以上这些词变疑问也是要提前的.

英语句子改为肯定句与否定句怎么改

否定句的常见形式和用法 中学英语表达否定含义的句式形式多样,用法灵活。

准确地掌握与否定相关的语句形式和用法,有助于提高英语阅读理解的准确性。

本文就中学英语中否定句的常见形式和用法总结如下: 一、常见否定句:否定副词not, seldom, never, hardly, rarely, nowhere等与谓语动词连用。

例如: I'm afraid that I can not attend your party this weekend. 恐怕这个周末我不能参加你们的聚会。

I can hardly understand what he said just now. 我不能理解他刚才所说的话。

注意:这些否定副词用于句首时,主句要使用倒装语序。

例如: Seldom does he go to work late. 他很少上班迟到。

Nowhere else can you find such a beautiful sunset. 你在别的地方不能见到如此美丽的日落。

Never in my life have I heard such nonsense! 我这辈子从来没有听过这种废话!二、否定祈使句:由“Don't 或Never+ 动词原形”所构成。

例如: Don't give up trying even though it is difficult to learn English! 英语虽然难学,但千万别放弃尝试! Do not cut down the tree that gives you shade. 切勿忘恩负义。

Never judge people by their appearance. 不可以貌取人。

三、全部否定:由“否定主语(否定代词或no+名词)+ 肯定谓语”所构成。

例如: Nothing is difficult if you put your heart into it. 世上无难事,只怕有心人。

None of us can speak French. 我们都不会讲法语。

No man is born wise. 人非生而知之。

注意:常用“neither/nor + 助动词/情态动词 + 主语”来表达“某人也不……”。

例如: Jim didn't know her secret, neither/nor did Jack. 吉姆不知道她的秘密,杰克也不知道。

If you don't accept his invitation, neither shall I. 如果你不接受他的邀请,我也不接受。

四、否定转移:常见的否定转移有两种情况。

1. 含有原因状语从句的主从复合句,形式上虽然否定主句的谓语,然而意义上则是否定该原因状语,译为“并不因为……而……”。

例如:Galileo was not ready to accept it just because Aristotle had said so.伽利略并不只是因为亚里斯多德说过某事如何如何,就轻易相信它。

The mountain is not valuable because it is high. 山不在高。

2. 当think, believe, suppose, expect, imagine等动词引导否定意义的宾语从句时,通常把从句中的not提前,把主句变成否定句,从句用肯定形式。

例如:We don't believe that the news is true. 我们相信这个消息不是真的。

I don't think that he is honest. 我认为他不诚实。

注意:(1)把这些发生否定转移的句子变为反意疑问句时,疑问部分应与宾语从句主谓部分构成反意疑问句。

例如:I don't think that he is honest, is he? 我认为他不诚实。

(2)not 常用在I think, I believe, I expect, I suppose, I guess, I'm afraid之后,构成省略句。

例如:---Do you think it will be a fine day tomorrow? ---I'm afraid not. ---你认为明天天气会好吗?---恐怕不是。

---Do you believe that Rocket will win the game? ---I believe not. ---你相信火箭队会赢吗?---我看不会。

五、否定疑问句:常用来表示反问、惊讶、建议、赞叹等语气。

例如:Don't you know these traffic rules? 难道你不知道这些交通规则吗?Aren't you supposed to be working? 你不是应该正在干活吗?You look pale. Why don't you have a rest? 你看起来脸色苍白,为什么不休息一会儿?Isn't it a lovely day? 天气多好啊!注意:在回答否定疑问句时,要根据具体事实作答。

例如:---Didn't you see the film Titanic yesterday? --- . I would like to have seen it. A. Yes, I did B. No, I didn't C. Yes, I didn't D. No, I did由于yes与肯定句连用,no与否定句连用,首先可排除C, D 两项。

A, B 形式都正确,但从题目语境中最后一句话“我倒希望自己看了那部电影。

”可知事实上我昨天没有看电影,故答案选B。

如果把题干最后一句话改为“It's very moving.”,则说明我昨天看过电影,正确答案就应该选A。

这种“根据事实作答”在运用中很不容易掌握,大家应该仔细体会其用法;同时,这种应答方法也适合于对“前否后肯型”反意疑问句和否定祈使句的回答。

例如:---You haven't been to Beijing, have you?--- . And I visited the Summer Palace. A. Yes, I have B. Yes, I haven't C. No, I have D. No, I haven't 从答语提示可知事实上我去过北京,故答案选A。

全句译为:“——你没有去过北京,是吗?——不,我去过。

我还去参观过颐和园。

”六、非谓语动词的否定式:通常把not或never放在非谓语动词to do, doing, p.p的前面。

例如:I advised him not to smoke but he wouldn't listen. 我劝他别抽烟,可他不愿意听。

Not having received a reply, she wrote him another letter. 由于没有收到他的回信,她又给他写了一封信。

Not allowed to take part in the game, they felt very disappointed. 因为不让他们参加比赛,他们感到非常失望。

七、双重否定句:由两个否定词搭配构成,表示一个较强的肯定语气。

例如:Without air or water, man can not live on the earth. 没有空气和水,人类是无法在地球上生存的。

Don't try to operate t...

一个英语句子的否定句怎么改?

先看句子里有没有be动词(am,is,are)、情态动词(can,may,would),如果有,在这些词后面直接加not如果没有,就在谓语动词前加don't,doesn't 或者didn't例如:He is a student. He isn't a student.She can fly a kite. She can't fly a kite.I go to school by bus. I don't go to school by bus.He likes to play football. He doesn't like to play football.
