陈述句变一般疑问句和否定句

1 I can help you.

2 Tom’s T-shirt is five dollars.

3 I often watch TV on Sunday.

一、陈述句变一般疑问句的方法：

1．对于助动词、情态动词、be动词作谓语的，把be动词，can，shall， will等放在句首，（some 改成any，my改成your等），句点改成问号。如：

He's a teacher. →Is he a teacher?

He can swim. →Can he swim?

He'd like to go there. →Would he like to go there?

2．对于实意动词作谓语的，动词原型借助do，三人称单数借助does，过去式借助did，加在句首，再把谓语改为动词原形，（some 改成any，my改成your等），句点改成问号。如：

I like him. →

Do I like him? Yes,I do /No,I don’t

He likes me. →

Does he like me? Yes,he does No,he doesn’t

I liked him. →

Did I like him? Yes,I did No,I didn’t

I will go there by bus. →

Will I go there by bus? Yes,I will No,I won’t

二、肯定句变否定句的方法

1、在be动词后加not。如：is not ， are not ， am not， was not， were not；

2、在can，should， will等后加not。如：cannot， should not， will not；

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。

4、 some 改成any。
