[探究-祈使句]
1. 概念:
祈使句是英语中的基本句型之一，常表示请求、命令、叮嘱、禁止、劝告等。
2. 用法
(1)祈使句无主语，肯定结构以动词原形开头。
祈使句中一般没有主语，事实上是省略了主语you。句末用感叹号或句点，肯定结构都以动词原形开头。例如：
Go and ask the teacher. 去问问老师。
Come and meet my family. 来见见我的家人。
(2)Do, Be, Let三种形式，委婉请求用“请”字。
祈使句的肯定句式有三种形式，即：
①Do型：行为动词原形＋副词！例如：
Sit down! 坐下！　Stand up! 起立！
②Be型：Be＋表语(如名词、形容词)！例如：
Be quiet！安静！
③Let型：Let＋宾语＋动词原形＋其他. 例如：
Let me help you.让我来帮助你。
[注意] 三种句型中Do型是最常见、最简单的一种结构。表示请求、劝告的祈使句还常常在句首或句末加上please, 以使语气更加缓和或客气，即：“Please…”或“…， please.”例如：
Come here, please. 请来这儿。
Please look after your little sister.
请照顾你的小妹妹。
(3)祈使句的否定结构是“Don’t＋动词原形＋其他．”例如：
Don’t go there, please. 请别去那儿。
Don’t be late. 不要迟到。
[注意] Let’s型祈使句，其否定形式为“Let’s not…”。 例如：
Let’s not have a rest. 咱们别休息了。
3. 特点
(1)祈使句一般没有主语，说话的对象是第二人称“你”或“你们”，所以可以理解为省略了主语you；
(2)肯定结构以动词原形开头，无时态和数的变化；
(3)祈使句的否定形式是在动词原形前加don’t；
(4)在表达请求时，可以加上please；表达比较强烈的语气时，句末可以用感叹号。
