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 don’t
2)Have they ten apples ? Yes , they have .No , they haven’t.
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your
Eg:I’m Alice .
Are you Alice ? Yes, I am. No, I’m not .
My mother is a nurse .
Is your mother a nurse ? Yes , she is . No , she isn’t .
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 isn’t .
一般疑问句作答用Yes或No 作答，遵循怎么问怎么答原则。
