No talking!
（2）否定祈使句。

before you finish your homework. 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。 Go and wash your hands.
快去洗手。 （命令）
Be quiet, please.
请安静。 （请求）祈使句 Be kind to our sister.
要对我们的妹妹友善。 （劝告）
Watch your steps.
走路小心。 （警告）
No littering.
不要乱扔垃圾。 （禁止）
Don’t forget to take an umbrella.
不要忘了带雨伞。 （叮嘱）祈使句的特点： (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”，所以也可以理解为省略了主语you。祈使句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don’t。 Please close the door.
请把门关上。
Sit down, 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。 Come to my office.
到我办公室来。
Stop! 停！
Hurry up! 快点！
Please don’t do it.
请不要这么做。
Don’t be late again.
不要再迟到了。(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 + not + 动词原形 + 其它成分。
e.g. Let’s go to school together.
咱们一起上学去吧。
Let him not go.
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。
e.g. Just a minute, please!
请稍等！
