（1）N + v.-ing! N talking!（2）否定祈使句。 Dn’t jump.（3）情态动词must表示“禁止”。 Yu mustn’t play with fire.（4）can’t表示“不允许”。 Yu can’t make any nise.（5）Yu aren’t allwed t …表示“不允许对方做某事”。 Yu aren’t allwed t watch TV at hme befre yu finish yur hmewrk.
祈使句用来表达叮嘱、劝告、希望、禁止、警告、请求或命令等。祈使句最常用来表达命令。

Presentatin
Be kind t ur sister. 要对我们的妹妹友善。 （劝告） Watch yur steps. 走路小心。 （警告） N littering. 不要乱扔垃圾。 （禁止） Dn’t frget t take an umbrella. 不要忘了带雨伞。 （叮嘱）
(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”，所以也可以理解为省略了主语yu。祈使句末用句号或惊叹号，句子读时用降调。 (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。
Please clse the dr. 请把门关上。 Sit dwn, please. 请坐。
(4) 在表达请求时，可以加上please; 表达比较强烈的语气时，可以用感叹号。
(5) Let’s 构成的祈使句往往用于提出建议。否定形式为：Let + 宾语 + nt + 动词原形 + 其它成分。如： Let’s g t schl tgether. 咱们一起上学去吧。 Let him nt g. 别让他走。
(6) 在请求、命令和口号中，常用无动词祈使句，它实际上是省略了动词，从而使句子更简洁有力。如： Just a minute, please! 请稍等！
口 诀 下面的口诀总结了祈使句的一般规律。一起来看看吧! 祈使句, 有特点, 动词原形摆在前, 否定句式也不难, Dn't 放在最前面, 其它一律都不变。
