小学英语肯定句变一般疑问句

小学英语句型转换之肯定句改否定句、一般疑问句一、肯定句改否定句的方法1.直接在be动词（am, is, are, was, were）后加not。

如：is not ，are not ，am not。

如果有some 就改成any，其余照抄。

2.直接在can，should，will等后加not。

如：cannot，should not，will not；如果有some 就改成any，其余照抄。

3.上述都没有的，在动词前加助动词否定形式don’t，doesn’t，didn’t。

如：——I am a girl.——I am not a girl.——You are a student.——You are not a student./You aren’t a student.——This is Tom’s bag.——This is not Tom’s bag./This isn’t T om’s bag.二、肯定句改一般疑问句的方法1.把be动词（ am, is, are, was, were））放在句首，如果句子里有some 就改成any，I改成you，my改成your，剩下的照抄，句号改成问号。

2.把can，shall，will，would，should ,could，may ,must等放到句首，如果句子里有some 就改成any，I就改成you，my就改成your，剩下的照抄，句号改成问号。

3.上述都没有的，就在句首加助动词Do，Does，Did帮忙，如果句子里有some 就改成any，I就改成you，my就改成your，剩下的照抄，句号改成问号。

4.注意：句首的第一个字母要大写，句尾标点应为“？”。

变一般疑问句时，肯定句是I am …，就把I am …变成Are you …？变一般疑问句时，肯定句I was …，就把I was …变成Were you …？如：——I am in Class 6.——Are you in Class 6？——You are from America.——Are you from America？——It is an orange.——Is it an orange？5.就一般疑问句回答一般疑问句有两种回答，即：肯定回答和否定回答。

EG: She can cook. → Can she cook?
肯定回答: Yes, she can. 否定回答: No, she can't
肯定句

小学语法—疑问句一、疑问句的分类疑问句就是提出疑问的句子。

分为：一般疑问句、特殊疑问句、选择疑问句和反意疑问句四种。

小学阶段不涉及反意疑问句和选择疑问句。

二、一般疑问句以Be动词，情态动词，助动词开头的疑问句，叫一般疑问句。

回答一般用“yes/no”来回答。

读的时候语音音调要上扬。

一般疑问句的结构:构成一般疑问句回答1Be动词在前Is he your father？Yes,he is/No,he isn´t Was she at home yesterday？Yes,she was/No,she wasn´t Are you at home？Yes,I am/No,I am not2情态动词在前Can you play the piano?Yes,I can/No,I can´t Could you do your homework?Yes,I can/No,I can´t3助动词在前Do you do your homework?Yes,I do/No,I don´tDoes she do her homework?Yes,she does/No,she doesn´t Did you do your homework?Yes,I did/No,I didn´tWill you do your homework?Yes,I will/No,I won´tIs she doing her homework.Yes,she is/No,she isn´t注意：回答一般疑问句时，肯定回答用“yes”，否定回答用“no”。

紧跟着的是人称（一般是代词），最后是一般疑问句的第一个词，如果是“no”否定回答还要把它加上not。

eg：Did you do your homework?你做作业了吗？Yes,I did/No,I didn´t(√)是的,我做了/不,我没有Yes,I didn´t(×)No,I did(×)Yes,I do(×)No,I doesn´t(×)三、肯定句如何变一般疑问句肯定句变一般疑问句与改成否定句窍门差不多，也是去找谓语（主要动词），再变化，遇到some要变成any。

英语句型之肯定句变一般疑问句情况一：1：寻找以下单词.a、Be 动词：am , is ，are, was, were。

b、小学常见的情态动词：can，must，should，will,2：如果有这些词，直接把这些词放在句子最前面,some 改成any，句号改成问号，其余照抄;(注意：如果主语是第一人称则变成第二人称eg:I am→Are you；We are→Are you; I can→Can you; Wecan→Can you；）eg: I am a teacher。

Are you a teacher?They are my friends。

Are they your friends?I can play basketball。

Can you play basketball？My sister is watching TV.Is your sister watching TV？情况二：情况一中单词找不到的句子，在句子前面加助动词do，does，（如何确定助动词用do, does,呢?根据句中动词，动词是原形的就用do, 动词是单三形式的就用does）注意：变疑问句时,句中有some，要将some变为any；句中动词用原形。

（如果主语是第一人称则变成第二人称）eg: I like the monkeys.Do you like the monkeys？My sister has a lovely dog.Does your sister have a lovely dog?I have some bread and milk every morning.Do you have any bread and milk every morning？。
