祈使句就是发出命令、请求等的句子,有两种结构:
1. 动词原形。如:Sit down. Pass me the book.
2. Let's (或let me\him) + 动词原形,如:Let's go. Let me have a look. Let him do it.
反义疑问句就是一个陈述句 + 简略问句,如:
He is a boy, isn't he"?
You are not a worker, are you?
We study English, don't we.
He has been to the city, hasn't he.
They can not come here, Can he?
注意:一定是前边肯定后边否定,前边否定后边则肯定;疑问句选的主动词一定要与陈述句的谓语动词呼应。
