英語怎麼把陳述句改為否定句?
一、陳述句:是用來陳述一件事情或表示一種看法,可分為肯定句和否定句兩種形式。
1、謂語動詞是be動詞,助動詞have, has, will,情態動詞can等時,隻要直接在這些詞後麵加not就構成否定形式。
eg. Lily has already read this new book. (改為否定句) Lily ______ ______ this new book ________. 2、謂語動詞是行為動詞而又沒有助動詞或情態動詞時,必須在謂語動詞前加助動詞,一般現在時加助動詞do ,第三人稱單數加does,一般過去時加did,再和not構成否定結構。
必須指出的是:don't, doesn't, didn't後都用動詞原形。
eg.1)Jill has lunch at school every day. (改為否定句) Jill _____ _____ lunch at school every day. 2)The children had a good time at the party. (改為否定句) The children ______ _____ a good time at the party. 3)Rose didn't drink any milk this morning.(改為肯定句) Rose ______ ______ milk this morning. 二、疑問句:是用來提出問題的句子。
A.一般疑問句:以be動詞, have /has/do等助動詞、can/may等情態動詞開頭,以yes或no來回答的問句。
它的基本結構是:Be/Have /Has/Did等助動詞(包括情態動詞)+主語+謂語(包括表語)+┄?回答常用簡略回答。
1、謂語動詞是be動詞、助動詞、情態動詞時,隻要直接把這些詞置於句首,句末改成問號。
eg. There's something wrong with his bike.(改成疑問句) ______ _____ _______ wrong with his bike? 2、謂語動詞是行為動詞時,必須在句首加上助動詞Do、Does(三單)、Did(過去式)加上這些助動詞後,句子中謂語動詞必須用原形。
eg. 1)Edison built a science lab himself when he was ten. (改成疑問句) ______ Edison ______ a science lab himself when he was ten? 2)Those Japanese like Chinese food.(改成疑問句) ______ those Japanese ________ Chinese food? 注意:在把肯定句改成否定句或一般疑問句的時候,要注意句中是否有already、some、something、somebody等詞,如果有也必須進行改變,already要改成yet,some、something、somebody等分別改成any、anything、anybody等。
另外,在改成否定句的時候注意把too改成either,both改成neither,all改成none等.在改成一般疑問句的時候,常常把第一人稱I、we改成第二人稱you。
B.特殊疑問句:以疑問代詞或疑問副詞開頭,提出疑問的句子。
它的基本結構是:特殊疑問詞+一般疑問句語序。
但是如果疑問詞在句子中作主語或作主語的定語,就用特殊疑問詞+陳述句語序。
常用的疑問詞有:what, who(whom), whose,which,when,where,how,why等,回答時針對問句中的代詞和副詞來回答,不用yes或no來回答。
1)對指物名詞或謂語動詞提出疑問,疑問詞用what ①The twins were making a kite when their mother came in. (劃線提問) ______ _____ the twins _____ when their mother came in? ②Mrs Turner asked her son to buy some eggs for supper. (劃線提問) _______ ______ Mrs Turner ask her son ______ _______? 2)對名詞前定語提出疑問,疑問詞應用which,而且必須和名詞連用。
I'm going to take the shirt on the right.(劃線提問) ______ _____ are you going to take? 3)對指人名詞或代詞提問用who,作賓語時提問用whom。
eg.Li Ping,they,his father 4)對物主代詞和名詞所有格提問用whose。
eg. Li Ping's coat→Whose coat my father→Whose father 5)對具體時間提出疑問,如 in the morning,last Sunday等,疑問詞用when;對具體幾點鍾提問,疑問詞應用what time。
6)對具體地點提出疑問,疑問詞應用where。
The pupils are having a picnic at the foot of the hill. (劃線提問) _____ _____ the pupils having a picnic? 7)對表原因的從句提問,常見的有because引導的從句,疑問詞應用why。
Xiao Cheng didn't go to the farm with us because he was ill. (劃線提問) _______ _____ Xiao Cheng go to the farm with us? 8)對方式或程度等提出疑問,用疑問詞How。
eg. go by bike like very much 9)對數量提出疑問,疑問詞為How many,要注意how many必須跟名詞的複數形式。
eg. two hundred sheep→How many sheep 10)對價格提出疑問,疑問詞用How much。
eg. I paid fifty yuan for the sweater. ______ ______ did you pay for the sweater? 11)對時間長度提出疑問,疑問詞應用How long。
eg. I've worked in that factory for two years. (劃線提問)96中考題 ______ _____ _______ you worked in that factory? 12)對時間頻率,如 once a year, twice a week等提問,疑問詞用How often。
13)對具體次數,如 once, twice, three times等提問,疑問詞用How many times。
eg. ______ did he call you the day before yesterday?Twice. 96中考題 A.What time B.How many times C.How much D.How long 14)對in+一段時間提問,疑問詞一般用How soon。
eg. Jane and her brother will finish the work in two hours. (劃線提問) _____ _____ _____ Jane and her brother finish the work? 15)對距離提出疑問,疑問詞用How fa...
英語怎麼改否定句和一般疑問句(要詳細的)
動詞的分類Be動詞:is,am,are,was,were助動詞:do,does,did,has,have,had動詞 情態動詞:can,must,may,should,等實義動詞:run,eat,play,like,等等.陳述句改為一般疑問句的改法:一般疑問句:以be動詞、助動詞、情態動詞為句首,句末有問號(?)的句子.例如:Is she a doctor.她是一名醫生嗎?Has she got any grapes?她有些葡萄嗎?(這裏的has是助動詞,got(get的原形)是有的意思.Can you fly?你會飛嗎?當句子中的謂語隻有實義動詞,沒有be動詞、助動詞、情態動詞的時候,句子變一般疑問句時要加do、does、did(do、dose的過去式)其中之一.如:The fox likes grapes.句子的謂語沒有be動詞、助動詞、情態動詞,隻有likes,like是實義動詞,因此,句首要加助動詞;又因為the fox是第三人稱單數,句首的助動詞就用does.句子的就變成Does the fox like grapes?注意原來likes中的s,要刪除.一般疑問句主語和be動詞、助動詞、情態動詞倒裝.沒有這三類詞時要加助動詞.如:She is a doctor.She usually goes to school at seven.Is she a doctor?Does she usually go to school at seven?記住:實義動詞始終在主語的後麵.注意:述句(句子後麵隻有句號的句子)給成一般疑問句時,一般情況下,還要把第一人稱I、we、my、our改成you、your,把some變成any.如:I have got some apples.I am making my aeroplane.變成:Have you got any apples?Are you making your aeroplane?We are watching TV.變成:Are you watching TV?還要注意:如果has、have、had、do、does、did後麵是名詞時,has、have就不是助動詞了,他們是實義動詞.改一般疑問時不能提前(一般情況下,所有實義動詞都不能提到主語前麵),要根據時態加助動詞do、does、did.如:She has breakfast everyday.Does she have breakfast everyday?否定句的改法首先要認清“否”就是“不”的意思,在英語中就是not或not的省略形式n't.否定句是在be動詞、助動詞、情態動詞後加not或not的縮略形式n't.人稱不變化.實義動詞不能直接加否定詞,須加助動詞doesn't(第三人稱單數)、don't、didn't.例如:I am English teacher.改成:I am not (aren't也可以)English teacher.She has got some apples.改成:She hasn't(has not也可以)got any apples.注意:一些否定詞hardly(幾乎不)few(很少可數)little(很少不可數)nothing(沒有)none(沒有人或物)等也是否定詞.含有此類否定詞的句子也是否定句.am not的否定縮略形式是aren't如:Su yang often plays football.可以改成:Su yang doesn't play football (at all).Su yang seldom plays football.Su yang never plays football.Some改成否定句一般也要改成any.

英語如何改否定句
簡單地說就是在動詞後麵加not,有is、am、are的句子會在這些詞後麵加not,I am (not) a boy.沒有is、am、are的句子會在動詞前加don't或者do not,I (don't)like basketball.如果有must、may、can這類的詞,在這類詞後麵加not,I can (not )walk.一般是根據句子的不同情況進行改動。
英語改有行為動詞的句子為否定句
很多英語句子是肯定形式,但卻表達否定意義,有的時候又恰恰相反。
稍不留神,就會對句子實際表達的意義產生相反的理解。
在絕大多數時候,句子的形式及其傳達的意義是統一的。
然而,無論中文還是英文,都會出現由於表達習慣、語氣的不同以及修辭等目的,用否定句式表達肯定含義或用肯定形式表達否定含義的情況,以加強語氣或使語氣更加委婉含蓄。
英語中常使用一些特殊的手段來達此目的。
理解否定形式表達肯定意義有以下兩種手段: 一、詞彙和短語手段。
1.cannot/couldn't或can /could +否定詞(not,never,hardly,scarcely)too以及比較級等等。
I can't wait to see him.我盼望著能早點見到他。
I could not feel better.我感覺再好不過了。
You cannot overemphasize the importance of it.其重要性無論怎麼強調也不過分。
2.否定詞(no,not,little,nothing,none,nobody)與 but,except等連用。
It leaves nothing to be desired.這已完美無缺。
Nobody but Peter can do it well.隻有彼得才能做好這件事。
二、使用一些特殊的句式。
1.否定的一般疑問句。
Don't you think we should try again?難道你不認為我們應該再試一試嗎? 2.特殊疑問句。
There is a lift,but why not use the lift?既然有電梯,為什麼不用呢? 3.過去時的no sooner...than句型。
No sooner had she got to Guangzhou,she called me.她一到廣州就給我打了個電話。
4.too...to句型。
I'm only too glad to help you.能為您效勞,我高興極了。
5.虛擬語氣。
If I haven't lost my watch!我的表要是不丟該多好! 6.含有not+表瞬間動作的動詞+ till/until短語或從句。
We can't go until Thursday.我們要到星期四才能去。
7.雙重否定句。
There is no smoke without fire.無風不起浪。
理解肯定形式的否定意義借助一些詞彙、短語和句型。
一、詞彙和短語手段。
1.在名詞及短語中,常見的有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.動詞及短語有escape(from)(逃過),ignore(忽略),lost(丟失)等。
I lost my book after getting offthe bus without it.當我沒帶書下了公共汽車之後才發覺把書丟了。
3.形容詞及短語有last(不願意的),deaf to(不聽),blind to(看不見)等。
He is the last man I want to see.我最不願意見到他。
4.介詞及短語except,instead of, but,beyond,above,past等。
It's quite beyond me(above me,past me,beyond my depth).這個我理解不了。
二、常用否定句型 1.too...to...,too...for... That's too much for me.這我可受不了啦。
2.stop(prevent,keep,hinder,protect,save,prohibit,dissuade)...(from)... Smoking is prohibited in most theaters.在大多數戲劇院裏禁止吸煙。
3.虛擬語氣句。
You should(ought to)have done it better.你本應做得更好。
(還不夠好) I could have come earlier.我本來能早點來的。
(實際上沒有早來) I wish he were here now.我希望他現在能在這兒。
(實際上他不在) If I only knew!要是我知道該多好。
(實際上不知道) They would rather die than surrender.他們寧死不降。
4.用before引導的從句表示"來不及……,不等,未……先……,以防?等否定含義。
Put on more clothes before you catch cold.多穿點衣服以防感冒。
5.預先安排的事未辦到或計劃落空。
I had hoped to save some more money to buy a new car.我本希望多攢點錢買輛新車。
6.用比較級句型表否定。
He knows more than he lets on.這件事他了解得很多,但不肯承認。
I know better than to believe him.我才不相信他那一套呢。
英語改為否定句怎麼改
句中有以下詞的,直接在這些詞後麵加NOT:1.BE動詞(am/is/are/was/were)2.情態動詞(can/may/must/need/should.)3.的在其後加NOT,構成時態和語態的助動詞(has/have/will/be...)如:I can swim.-------I can't swim.She will come to see me next week.-----She (will not)(或won't) come to see me next week.如果沒有以上的詞,則句子為一般現在時或一般過去時的肯定形式,變否定句時,先將動詞變為原形,在動詞前麵助動詞DO(DOES/DID),並在助動詞之後加否定詞NOT.助動詞要根據時態和人稱選用相應的.一般現在時用DO/DOES,其中DOES用於第三人稱單數主語,DO用於除第三人稱單數之外的其它主語.DID用於一般過去時,不論人稱.例如:He goes to school on weekdays.-----He (doesn't go) to school on weekdays.We went shopping last Monday.-------We (didn't go) shopping last Monday.We like watching TV.------We (don't like) watching TV.另外,除了NOT ,還有一些具有否定意義的詞,以上是基本的,先記住這些.以上這些詞變疑問也是要提前的.
英語句子改為肯定句與否定句怎麼改
否定句的常見形式和用法 中學英語表達否定含義的句式形式多樣,用法靈活。
準確地掌握與否定相關的語句形式和用法,有助於提高英語閱讀理解的準確性。
本文就中學英語中否定句的常見形式和用法總結如下: 一、常見否定句:否定副詞not, seldom, never, hardly, rarely, nowhere等與謂語動詞連用。
例如: I'm afraid that I can not attend your party this weekend. 恐怕這個周末我不能參加你們的聚會。
I can hardly understand what he said just now. 我不能理解他剛才所說的話。
注意:這些否定副詞用於句首時,主句要使用倒裝語序。
例如: Seldom does he go to work late. 他很少上班遲到。
Nowhere else can you find such a beautiful sunset. 你在別的地方不能見到如此美麗的日落。
Never in my life have I heard such nonsense! 我這輩子從來沒有聽過這種廢話!二、否定祈使句:由“Don't 或Never+ 動詞原形”所構成。
例如: Don't give up trying even though it is difficult to learn English! 英語雖然難學,但千萬別放棄嚐試! Do not cut down the tree that gives you shade. 切勿忘恩負義。
Never judge people by their appearance. 不可以貌取人。
三、全部否定:由“否定主語(否定代詞或no+名詞)+ 肯定謂語”所構成。
例如: Nothing is difficult if you put your heart into it. 世上無難事,隻怕有心人。
None of us can speak French. 我們都不會講法語。
No man is born wise. 人非生而知之。
注意:常用“neither/nor + 助動詞/情態動詞 + 主語”來表達“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,傑克也不知道。
If you don't accept his invitation, neither shall I. 如果你不接受他的邀請,我也不接受。
四、否定轉移:常見的否定轉移有兩種情況。
1. 含有原因狀語從句的主從複合句,形式上雖然否定主句的謂語,然而意義上則是否定該原因狀語,譯為“並不因為……而……”。
例如:Galileo was not ready to accept it just because Aristotle had said so.伽利略並不隻是因為亞裏斯多德說過某事如何如何,就輕易相信它。
The mountain is not valuable because it is high. 山不在高。
2. 當think, believe, suppose, expect, imagine等動詞引導否定意義的賓語從句時,通常把從句中的not提前,把主句變成否定句,從句用肯定形式。
例如:We don't believe that the news is true. 我們相信這個消息不是真的。
I don't think that he is honest. 我認為他不誠實。
注意:(1)把這些發生否定轉移的句子變為反意疑問句時,疑問部分應與賓語從句主謂部分構成反意疑問句。
例如:I don't think that he is honest, is he? 我認為他不誠實。
(2)not 常用在I think, I believe, I expect, I suppose, I guess, I'm afraid之後,構成省略句。
例如:---Do you think it will be a fine day tomorrow? ---I'm afraid not. ---你認為明天天氣會好嗎?---恐怕不是。
---Do you believe that Rocket will win the game? ---I believe not. (=I don't believe so.)---你相信火箭隊會贏嗎?---我看不會。
五、否定疑問句:常用來表示反問、驚訝、建議、讚歎等語氣。
例如:Don't you know these traffic rules? 難道你不知道這些交通規則嗎?Aren't you supposed to be working? 你不是應該正在幹活嗎?You look pale. Why don't you have a rest? 你看起來臉色蒼白,為什麼不休息一會兒?Isn't it a lovely day? 天氣多好啊!注意:在回答否定疑問句時,要根據具體事實作答。
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由於yes與肯定句連用,no與否定句連用,首先可排除C, D 兩項。
A, B 形式都正確,但從題目語境中最後一句話“我倒希望自己看了那部電影。
”可知事實上我昨天沒有看電影,故答案選B。
如果把題幹最後一句話改為“It's very moving.”,則說明我昨天看過電影,正確答案就應該選A。
這種“根據事實作答”在運用中很不容易掌握,大家應該仔細體會其用法;同時,這種應答方法也適合於對“前否後肯型”反意疑問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 從答語提示可知事實上我去過北京,故答案選A。
全句譯為:“——你沒有去過北京,是嗎?——不,我去過。
我還去參觀過頤和園。
”六、非謂語動詞的否定式:通常把not或never放在非謂語動詞to do, doing, p.p的前麵。
例如:I advised him not to smoke but he wouldn't listen. 我勸他別抽煙,可他不願意聽。
Not having received a reply, she wrote him another letter. 由於沒有收到他的回信,她又給他寫了一封信。
Not allowed to take part in the game, they felt very disappointed. 因為不讓他們參加比賽,他們感到非常失望。
七、雙重否定句:由兩個否定詞搭配構成,表示一個較強的肯定語氣。
例如:Without air or water, man can not live on the earth. 沒有空氣和水,人類是無法在地球上生存的。
Don't try to operate t...
一個英語句子的否定句怎麼改?
先看句子裏有沒有be動詞(am,is,are)、情態動詞(can,may,would),如果有,在這些詞後麵直接加not如果沒有,就在謂語動詞前加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.
