◆含义：祈使句是用来表示请求、命令或建议等的一种句型。其主语一般为第二人称you，但通常省略。祈使句的句末一般用句号．表示较强语气时用感叹号。为了使祈使句显得更委婉、有礼貌，可在开头或结尾加上please。

eg：Listen to me，please．请听我说。
②Be型祈使句．be动词+其他．

③Let型祈使句：Let +sb．+动词原形+其他．
eg：Let’s play football．让我们踢足球吧。
④No型祈使句：No +n.-ing／名词(表示禁止!)
eg：No smoking!禁止吸烟!
No photos!禁止拍照!
◆祈使旬的否定形式
通常是在谓语动词前加don’t。但要注意以1et开头的祈使句，其否定形式是：“Don’t +let+宾语+动词原形+其他”或“Let+宾语+not+动词原形+其他”。
eg：--Don’t let him go swimming．
--Let him not go swimming．不要让他去游泳。
