2. 【英语陈述句改疑问句方法】

要将陈述句变成一般疑问句，可以遵循下列步骤：1.看句中有没有be动词（am、is、are、was、were）、助动词（do、does、did、have、had）或情态动词（can、must、will、may等），如果有，将其提到句首，句末打上问号即可.例：It was rainy yesterday.→Was it rainy yesterday?Tom's father can play the piano.→Can Tom's father play the piano?I have finished my homework.→Have you finished your homework?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.具体方法是：①如果谓语动词是原形，则借do；②如果谓语动词是一般现在时第三人称单数形式，则借does；③如果谓语动词是过去式，则借did.需要注意的是，借does或did后，原句的谓语动词要变回原形.例：They go to school by bike.→Do they go to school by bike?Bill gets up at 6:30 every day.→Does bill gets up at 6:30 every day?The students saw a film yesterday.→Did the students see a film yesterday？二、陈述句变一般疑问句应注意的事项陈述句变成一般疑问句除了遵循上述规则以外，还应注意下列几点：1.如果陈述句中有第一人称，则变问句时最好要变为第二人称.例：I usually have lunch at school.→Do you usually have lunch at school?My father is playing soccer.→Is your father playing soccer?2.如果陈述句中有some，则变问句时往往要变成any .例：There is some water on the playground.→Is there any water on the playground?3.复合句变一般疑问句通常只变主句，从句不变.例：I know he comes from Canada.→Do you know he comes from Canada?4.如果句中含有实义动词have且表示“有”时，除借do外，也可将其直接提到句首.例：I have some friends in America.→Have you any friends in America?/Do you have any friends in America？三、总结：将陈述句改成一般疑问句的方法：三步法1、有be动词，则把be动词放在句首，剩下的照抄，（some 改成any,I改成you,my改成your，）句点改成问号.2、有情态动词，则把can,shall,will等放到句首，剩下的照抄，（some 改成any,I改成you,my改成your，）句点改成问号.3、没有be动词，也没有情态动词的，则将助动词Do/Does/Did放到在句首，谓语动词变回原形，剩下的照抄，（some 改成any,I改成you,my改成your，）句点改成问号.。

4. 【怎么变一般疑问句和特殊疑问句】

把一个陈述句变成一个一般疑问句首先要看句子是什么时态如果是一般现在时或一般过去时的句子（这两中时态的陈述句中一般没有助动词）要在句首加一个助动词（do/does/did）一般现在时： They often go to the park at the weekends. ---Do they often go to the park at the weekends? I often do some shopping on Sunday. ---Do you often do some shopping on Sunday?His mother usually washes clothes on Saturday.---Does his mother usually wash clothes on Saturday?Tom often does his homework in the evening. ---Does Tom often do his homework in the evening？一般过去时：We went to the concert last Sunday.---Did you go to the concert last Sunday?He did some washing yesterday.---Did he do some washing yesterday？注意：1、第二个例句中句首的do 是助动词，often后的 do是主要动词. 2、一般现在时 第三人称单数作主语时，（变问句时）用does；一般过去时（这种时态的 谓语动词用过去式，而过去式除了be动词外，没有人称和数的变化，既：不论是第一、第二还是第三人称，不论单数还是复数，都用过去式）用did . 3、do/does/did 后边的主要动词要用原形，尤其是后两个要注意把原句（陈述句）中的动 词改为原形.如果是其它时态（除一般现在和一般过去两种时态外，谓语中都有助动词）将助动词移置句首即可变成一般疑问句.现在进行时I am speaking.--Are you speaking? He is watching TV.--Is he watching TV. They are playing basketball.--Are they playing basketball？过去进行时Lily was doing her homework at that time. --Was Lily doing her homework at that time?The students were having an English lesson this time yesterday. --Were the students having an English lesson this time yesterday？一般将来时They will go to the park by bus.--Will they go to the park by bus?We are going to visit the Science Museum next Sunday.--Are you going to visit the Science Musuem next Sunday？现在完成时I have finished my homework.--Have you finished your homework?He has come.--Has he come？如果谓语是连系动词be (am is are was were) 将be动词移到句首.I am a nurse.--Are you a nurse? She is an American girl.--Is she an American girl?They are in the classroom.--Are they in the classroom？特殊疑问句：特殊疑问词+一般疑问句子（疑问词作主语除外）变特殊疑问句就是把句中被提问的部分（划线部分）用一个恰当的疑问词代替置于句首，再把原句变成一个一般疑问句.如：He does his homework at home in the evening.一句对句中的地点at home进行提问 用whereWhere does he do his homework in the evening？对句中的时间in the evening进行提问 用whenWhen does he do his homework at home？对所做的事情does his homework进行提问 用what ----do (do what)What does he do at home in the evening？对句中的主语he进行提问 用whoWho does his homework at home in the evening？对主语或主语中的一部分进行提问时，用疑问词取代被提问的部分就行，语序不变.。
