英语中如何把陈述句变成一般疑问句和否定句一、一般疑问句什么是一般疑问句: 用Yes 或No 作答的疑问句叫一般疑问句。
要将陈述句变成一般疑问句,可以遵循下列步骤:1.句子中有be(am is are was were ) 动词、情态动词( can would may )、will 时,只要直接把这些词置于句首,句末改成问号。
例:It is rainy today. →Is it rainy today?Tom's father can play the piano → Can Tom's father play thepiano?2.如果句中没有be 动词、助动词或情态动词,则根据谓语动词的形式借助do 的相应形式放在句首,必须在句首加上助动词Do 、Does (单三)、Did (过去式)加上这些助动词后,句子中谓语动词必须用原形。
英语中如何把肯定句变成否定句例:They go to school by bike. →They do not go to school by bike.二.肯定句变否定句1.句子中有be(am is are was were ) 动词、情态动词( can would may)、will 时,只要直接在这些词后加not.例:It is rainy today. →It is not rainy today. Tom's father can play the piano → Tom's father can not play the piano .2.谓语动词是行为动词时,必须在动词前加上动don't 、doesn' t (单数第三人称)didn ' t (过去式), 句子中谓语动词用原形。
例:They go to school by bike. →They don 't go to school by bike.注意:1. 在把肯定句改成否定句或一般疑问句的时候, 要注意句thing 、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。
一陈述句改为一般疑问句:1.当句子中含有be 动词(am is are )或情态动词(can, must,等)时,把be动词(am is are )或情态动词(can, must,等)提到句首。
其中句中有I 的要变成you,如:I am a student-------Are you a student?2.当句中含有实义动词时,必须在句首加DO/Does/, 具体情况分以下三方面:㈠当句子中含有动词原型时,在句子前加Do, 其中句中有I 的要变成you. 如:I like English------Do you like English?㈡当句子中含有的动词加s或es时,即主语为第三人称单数时,在句子前加Does. 动词要变回原形.如:He likes music.------Does he like music?二、陈述句改为否定句:1.当句子中含有be 动词(am is are)或情态动词(can, must,等),要在be 动词(am is are)或情态动词(can, must,等)后加not. 如:I am a student-------如:I am not a student2.当句中含有实义动词时,必须在原句动词前加don’t, 或doesn’t㈠当句子中含有动词原型时,在动词前加don’t:如:I like music,-----I don’t like music. ㈡当句子中含有的动词加s或es时,即主语为第三人称单数时,在句子中的动词前加doesn’t再把动词变原型: 如:He likes music.-----He doesn’t like music.三一般疑问句的肯否回答:1疑问句中有be 动词(am is are )或情态动词(can, must,等)时,肯定回答用Yes,主语代词+ am/is/are或can, must,等. 如:Are you a student?------Yes, I am。
陈述句变一般疑问句和否定句一般疑问句=助动词+陈述句剩余部分否定句=找出助动词,在助动词后加not一、助动词:帮助动词构成时态、语态、感情色彩和否定疑问句。
它包括be动词, do的各种形态,have的各种形态,will等情态动词。
I am watching TV. am 在句子里不能独立做谓语,也没有具体的含义。
二、有的助动词既可以做助动词又可以做行为动词:be动词可以做行为动词,也可以做助动词。
行为动词是有实际意思,表示具体的动作,在句子里能够独立充当句子成分。
助动词是不具有实际意思,在句子里不能独立充当句子成分,只是帮助动词构成各种时态和语态三、学会通过助动词来判断谓语动词,来帮助读懂句子。
1、四类助动词,只有do是包含在谓语动词里的,其它的三个都是在谓语动词前面的。
2、很多助动词既可以做助动词又可以做实意动词。
当做助动词的时候,后面跟动词。
当做行为动词的时候,后面跟名词。

I was/We were…-----Were you….?I /We can…-----Can you…..? I /We have +过去分词…..------Have you…….?2.当句中含有实义动词时,也就是句子不含上面所提到那些助动词时,必须在句首加DO/Does/Did,具体情况分以下三方面:㈠当句子中含有动词原型时,在句子前加Do, 其中,I+动词。
------Do you…?如:①I like music.---Do you like music? ②They work here.----Do they work here?㈡当句子中含有的动词加S或ES时,即句子是一般现在时,且主语为第三人称单数时,在句子前加Does.如:①He likes music.------Does he like music?②Tom comes from China.-----Does Tom come from China?(注意在此情况下,应把疑问句中的动词变原型。

英语中如何把陈述句变成一般疑问句和否定句一、
一般疑问句
什么是一般疑问句:用Yes 或No 作答的疑问句叫一般疑问句。
要将陈述句变成一般疑问句,可以遵循下列步骤:
1.句子中有be(am is are was were )动词、情态动词(can would may )、will 时,只要直接把这些词置于句首,句末改成问号。
例:It is rainy today. →Is it rainy today? Tom's father can play the piano→Can Tom's father play the piano?
2.如果句中没有be 动词、助动词或情态动词,则根据谓语动词的形式借助do 的相应形式放在句首,必须在句首加上助动词Do 、Does (单三)、Did (过去式)加上这些助动词后,句子中谓语动词必须用原形。
英语中如何把肯定句变成否定句
例:They go to school by bike. →They do not go to school by bike.
二.肯定句变否定句
1.句子中有be(am is are was were ) 动词、情态动词(can would may)、will 时,只要直接在这些词后加not.
例:It is rainy today. →It is not rainy today.
Tom's father can play the piano →Tom's father can not play the piano .
2. 谓语动词是行为动词时,必须在动词前加上动don’t 、doesn’t(单数第三人称)didn’t(过去式), 句子中谓语动词用原形。
例:They go to school by bike. →They don’t go to school by bike.
注意:1.在把肯定句改成否定句或一般疑问句的时候, 要注意句thing 、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。
例:There is some water on the playground.
→Is there any water on the playground?
2.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.
3.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, my /our改成第二人称 your, me/ us改成第二人称you 。
例:I usually have lunch at school→Do you usually have lunch at school? My father is playing soccer. →
Is your father playing soccer?
三. 一般疑问句的回答
一般疑问句往往采用简短回答,共由三部分(三个单词)组成,
对这三部分(三个单词)的确定可以概括例下:
1. 第一个词:不是Yes 就是No 。
(有时根据语气的不同,Yes 可
由Sure, Certainly, Of course等代替.
2.第二个词:问谁答谁。
即答语中的主语须与问句的主语一致(但
必须用主格代词)。
例:Does she clean her room every day? Yes, she does. Is Anna′s father a doctor? No,he isn′t.
Are you a student ? Yes, I am .No, I’m not
如果主语是 this that,回答时用 it 代替,如果问句中主语these, those,
回答时用 they 代替。
3. 第三个词:用什么问,用什么答。
即沿用问句中的引导词。
Can Jim play soccer? Yes, he can.
Does Mr Bean speak English? Yes, he does.
4.用No 开头作否定回答时, 结尾要加上 not。
因为回答必须是
三部分,所以否定回答必须缩写,而肯定回答不能缩写。
Is Lin Lin in Class 3? Yes, she is. / No, she isn′t. 或(No, she′s not)
