初一英语句型转换

陈述句变一般疑问句和否定句

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?

He likes me. →Does he like me?

I liked him. →Did I like him?

补充：陈述句变特殊疑问句 先改一般疑问句，去掉要提问的成分，再在句首加相应

疑问词。如：

will go there by bus. Will I go there by bus?

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。

根据句后括号内的要求改写句子

陈述句:陈述一件事实的句子，句末用句号。

一般疑问句：对一件不确定的事进行提问，要对方确定。回答用yes/no,主语+be/情态动词/助动词（谁问谁答）

陈述句变一般疑问句的方法：有be（am/is/are）/情态动词（can /may/must„）/助动词的，直接将它提到主语前。若没有这些词，就在句首加Do/Does/Did 。有Some变成any, I /we变成you, my/our变成your,在句末加“？”
