祈使句的语法概念及特点 一般说来,祈使句有以下特点： 1、祈使句的主语为第二人称（you）,会被省略. 2、祈使句的谓语动词一律用原形. 3、祈使句句末的标点符号一般是句号或感叹号. 4、 表示表示请求、命令、劝告、建议的语气. 二、祈使句的分类 按照祈使句谓语动词的不同,我们通常可以将祈使句分成如下三种类型： 1、Be型：即系动词be打头的祈使句.如：Please be careful next time.下次请小心些. 2、Do型祈使句：即行为动词原形打头的祈使句.如：Go straight along this street,please.请沿此街笔直走. 3、Let型祈使句：即以动词let开头的祈使句.如：Let’s go out to dinner.我们出去吃饭吧. 三、祈使句的否定句 1、在谓语动词前加don’t.例如：Don’t be late for school.上学别迟到.Don’t play football in the street.别在街上踢球 四、祈使句的反意疑问句 1）以Let’s打头的祈使句,用“shall we?”.例如：Let’s play soccer together, shall we? 2) 其他祈使句,用“will you?”. 例如：Let us have a try, will you?
