1. 将陈述句变为否定句和一般疑问句。

首先找准谓语动词,如果谓语动词是be 动词(am、is、are、was、were)、情态动词和助动词时,变一般疑问句用“一调,二改,三问号”。

Eg:She is a girl.→ Is she a girl?

变否定句时情、助、be 后加not。

I can help you.→I can’t help you.

如果谓语动词是实义动词,变一般疑问句使用助动词(do、does、did),变否定句时用(don’t、doesn’t、didn’t),切记(does、did、doesn’t、didn’t)后谓语动词要变原形。

Eg:Li Ming goes to school by bus. →Does Li Ming go to school by bus?

LiMingdoesn’t go to school by bus.

2. 同义句转换主要考查同义、近义短语、反义词。

Eg:She is busy doing homework. →She is busy with homework.

这一题考查同义词组be busy doing sth 与be busy with sth。


3. 就划线部分提问

根据划线部分先确定特殊疑问词,再把原句变成一般疑问句,去掉划线部分即可。

Eg:①I was born in China. → Where were you born?

②LiMing goes to Beijing once a year.

How often does LiMing go to Beijing?

第一小题是“in China”是对地点的提问,所以用where;而第二小题是对频率的提问则用how often。
