祈使句（Imperatives） 祈使句是用来表达命令、请求、劝告、警告、禁止的句子。祈使句一般以动词原形开头，无时态和数的变化，句末用句点或者感叹号，读时用降调，在祈使句的句首或者句末加上please，以使语气更加委婉客气。祈使句有肯定和否定两种形式。1. 肯定的祈使句（1）动词原形+其他 Stand up, please. = Please stand up. 请起立。（2）Be + adj. Be careful! = Look out! = Take care! 小心 / 当心！（3）Lets + 动词原形 Lets go to school together. 咱们一起上学去吧。辨析：lets与let uslets 是包括讲话者的谈话对象在内。Lets try it again.让我们(一起)再试试吧。let us不包括讲话者的谈话对象在内。Let us try it again. 让我们(自己)再试试吧。2. 否定的祈使句(1) Dont + 动词原形 Dont stand up. 别站起来。 Dont be careless. 别粗心。 Dont let them play with fire. 别让他们玩火。（2）Lets ( let sb ) + not + 动词原形 Lets not say anything about it. 对于这件事，咱们什么也别说。 Let them not play with fire. 别让他们玩火。 Never+动词原形+其他。 Never be late for school.上学从来不要迟到。 有些祈使句可用no开头，用来表示禁止。 No smoking！禁止吸烟！3.祈使句的反意疑问句(1) 肯定祈使句的反意疑问句反问部分用will you 或wont you。 Please open the door, will/ wont you? 请把门打开，好吗？(2) 否定祈使句的反意疑问句反问部分只用will you。 Dont be late again, will you? 别再迟到了，行不行？(3) 以lets开头的祈使句反意疑问句反问部分用shall we。 Lets turn on the TV, shall we? 我们把电视打开，好吗？ 只有以lets开头的祈使句的反意疑问句的反问部分才用shall we，而let us 开头的祈使句的反意疑问句的反问部分应为will you或wont you.如：Let us stay here, will/ wont you? 请（你）让我们留在这好吗？4. 祈使句的回答因为祈使句通常表示将来要发生的动作，所以回答祈使句时，一般用will或者wont。Dont forget to do your homework.不要忘记做你的作业。I wont. 我不会忘记的。随堂练习：一、单项选择1.
