知识点大全SA语法：祈使句祈使句的概念：表达说话人对对方的劝告、叮嘱、请求或命令等。

因此，祈使句中一般没有主语，但根据其句意，实际上是省略了主语you。

特点：祈使句句末用感叹号或句号，朗读时，常用降调。

在表达请求或劝告时，在祈使句前或句末可加上please，以使句子的语气更加缓和或客气。

祈使句一般没有时态的变化，也不能与情态动词连用。

语法：祈使句的肯定句式祈使句的肯定句式一般分为以下三种类型：1. Do型。

结构：实意动词的原形＋（其它成分）e.g. Go! 走！/出发！e.g. Leave, please! 请离开！e.g. Go home after school. 意译：放学给我回家。

2. Be型。

结构：be动词＋表语(形容词、名词或介词短语等) ＋(其他成分)。

e.g. Please be quiet! 请安静。

e.g. Be a good boy! 做个乖孩子。

e.g. Be good to people, please. 请友好待人。

e.g. Be careful when you cross the street.过马路时要小心。

3.Let型。

结构：Let＋宾语＋动词原形＋(其它成分)。

例如：e.g. Let it go. 随它吧。

e.g. Let’s go now. 让我们现在就出发吧。

e.g. Let us go home, please. 请让我们回家吧。

（啰嗦：注意let us与let’s的区别）语法：祈使句的否定句式祈使句的否定句式，通常情况下在句首加上Don’t，一般分为以下四种类型：1.Do型与Be型句首加Don’t。

e.g. Don’t say that again! 别再那样说了！e.g. Don’t come back! 别回来了！e.g. Don’t be loud. 别吵。

e.g. Don’t be sad. 别难过了。

e.g. Don’t be afraid of me. 别怕我。
