一、定义 用于表达命令、请求、劝告、警告、禁止等的句子。二、特点 ① 祈使句一般没有主语,说话的对象都是第二人称“你”或“你们”,所以可理解为省略了主语 yu。
② 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dn’t。④ 在表达请求时,可加上 please;表达比较强烈 的语气时,可用感叹号。
1. D 型 :动词原形 + 宾语 + 其它成分. eg: Please have a seat here. 请这边坐。 有的祈使句在意思明确的情况下,动词可省略。 eg: This way, please. = G this way, please.

3. Let 型祈使句:Let十sb.+动词原形+其他. eg: Let’s play basketball. 我们去打篮球吧。4. N 型祈使句:N十v.-ing/名词(表示禁止)! eg: N smking! 禁止吸烟! N phts! 禁止拍照!
1. 通常在谓语动词前加 dn’t。但要注意以let 开头的祈使句,其否定形式是: Dn’t+let+宾语+动词原形+其他. Let+宾语+nt+动词原形+其他.eg: Dn’t let him g swimming! =Let him nt g swimming! 不要让他去游泳!
2. 有些可用 n 开头,用来表示禁止性的祈使句,结构为:“N+名词/动名词”。eg: N fire! 禁止烟火! N fishing! 禁止钓鱼!
五、加强语气的祈使句在肯定祈使句中,我们可以用助动词 d 来加强语气。eg: D cme, please! 请一定要来! D be quiet, please! 请务必安静!
