高中语法详解：祈使句的简单了解

祈使句的反意疑问句

1.祈使句的反意疑问部分为肯定形式,要用shall,will.如：

Pass me the book,will you?

2.Let’s表示第一人称的祈使句,反意疑问句为“Shall we?”.如：

Let’s go for a walk,shall we?

Let’s forget it,shall we?

3.Let me和Let us 表示第二人称的祈使句,反意疑问句为“will you?”.如：

Let us go for a walk,will you?

4.其它行为动词引起的祈使句,无论其陈述部分是否定还是肯定的祈使句,多用“will you?”,表一种客气的语气.如：

Listen to me,will you?

Don’t tell anyone about it,will you?

但在肯定的祈使句后有时也用“won’t you?”表“提醒对方注意”或表“邀请”.如：

Have a cup of coffee,won’t you?

Come in and take a seat,won’t you/will you?

祈使句用于两个重要句型中

1.“祈使句+and+表结果的陈述句”用来叙述肯定的条件.

2.“祈使句+or(else)+表结果的陈述句”用来叙述否定的条件,or(else)表示“否则;要不然”.试比较：

Hurry up and you’ll catch the train.(=If you hurry up,you’ll catch the train.)

Hurry up,or you’ll miss the train.(=If you don’t hurry up,you’ll miss the train.)

祈使句由直接引语变成间接引语

当祈使句由直接引语变成间接引语时,其常用结构为“ask/request/tell/order sb(not)to do sth”.

如：“Speak loudly,please!” the teacher said to me.(=The teacher asked me to speak loudly.)

“Don’t smoke in the meeting room!” he said to Tom.(=He told Tom not to smoke in the meeting room.)
