一般疑问句讲解及练习.doc

一般疑问句在英语学习中，一般疑问句的转换及回答是经常碰到的问题，现在我们就来探讨一下一般疑问句的问题。一 什么是一般疑问句以be动词（am is are）,助动词（do does have）,情态动词（can）开头的句子，用Yes或No 作答。读升调！二 陈述句变一般疑问句遵循1找2接 1找 看句中有没有be动词（am is are）,助动词（do does have has）,情态动词（can），如果有，直接将其放句首，句末打上问号。Eg: He is three years old . (变一般疑问句） Is he three years old ? They are good friends .(变一般疑问句） Are they good friends ? She can swim and draw.(变一般疑问句） Can she swim and draw ? 2借 如果句中有没有be动词（am is are）,助动词（do does have has）,情态动词（can），则根据谓语动词的形式借助do 或does放句首。具体方法：如果谓语动词是原型，则借助do 放句首；如果谓语动词是第三人称单数形式，则借助does 放句首,原句的谓语动词要变回原型。Eg:They go to school by bike . Do they go to school by bike ? He goes to school by bike . Does he go to school by bike ? 3 如果句中有实意动词have/ has ,且表示有时，可以“借”也可以“找”，即可以借do/does放句首，也可以直接把have/ has放句首。Eg:They have ten apples . 1)Do they have ten apples ? Yes , they do . No , they dont 2)Have they ten apples ? Yes , they have .No , they havent. 陈述句变一般疑问句注意事项： 1如果陈述句中有第一人称，变一般疑问句时一定要变成第二人称。 I/We变成 you My/Our变成yourEg:Im Alice . Are you Alice ? Yes, I am. No, Im not . My mother is a nurse . Is your mother a nurse ? Yes , she is . No , she isnt . 2 如果陈述句中有some，变一般疑问句时一定要变成any。Eg:There is some water on the table . Is there any water on the table ? Yes, there is. No, there isnt .一般疑问句作答用Yes或No 作答，遵循怎么问怎么答原则。将下列句子改成一般疑问句：并做肯定回答和否定回答1. We are classmates. 2.He can clean the floor.3. I am a doctor. 4. There is a bird in the tree. 5. There are some stars in the sky. 6. I love my parents.7. I play computer games every night. 8. We have a pleasant home. 9.My mother can dance and sing.10.Mary often helps Lucy with her English.
