一般疑问句

用Yes 或No 作答的疑问句叫一般疑问句。其结构是be 动词（am /is /are ) /助动词/情态动词+主语+其他成分

通常回答为：肯定：Yes，+主语+提问的词.

否定：No，+主语+提问的词+not.

Are you from Japan﹖Yes ,I am．/ No, I'm not．

Is her sister doing her homework now﹖Yes, she is．/ No, she

isn't．Does he work in a bank﹖Yes, he does．/ No, he doesn't．

Can you speak French﹖Yes, I can．/ No, I can't．

一: 般疑问句还有下列特点：

1、以be 动词、助动词或情态动词开头；例：Is your father a teacher? Does Catherine like animals? Can Jenny speak French?

二: 如何将陈述句变成一般疑问句？

要将陈述句变成一般疑问句，可以遵循下列步骤：

1.如句中有be 动词（am、is、are、was、were）情态动词（can、may、must …）或助动词（do、does、did、 have、had（完成时中））时，可直接将它们提到句首，句末打上问号即可。主语为第一人称，应将其改为第二人称。

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：如果谓语动词是原形，则借do；如果谓语动词是一般现在时第三人称单数形式，则借does；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 get up at 6:30 every day?

The students saw a film yesterday.

→Did the students see a film yesterday?
