多么令人激动的消息呀!5、不准钓鱼!好热的天啊!二、【新课讲授】祈使句:是用来表示命令、请求、建议或劝告对方做某事或别做某事等。

谓语动词一律用原形。

句子中通常不用主语,句末用惊叹号或者句号,用降调。

1.肯定的祈使句A)句型:动词原形~.(省略主语)Stand up.起立。

Be quiet,please.请安静。

B)有时,为了加强语气,可以在动词之前加doDo sit down.务必请坐。

Do study hard.一定要努力学习。

※比较:祈使句和陈述句※陈述句:You sit down.你坐下来。

祈使句:Sit down.坐下(省略主语you)C)用客气的语气表示祈使句时,可在句首或句尾加上please,但如果在句尾加please,那在please之前一定要加一个逗号“,”。

Go this way,please.请这边走。

祈使句中如果有唤语,一定要用逗号“,”隔开,放在句首或句尾。

Li Ming,come here.李明,过来。

= Come here,Li Ming.过来,李明。

D)句型:•Let+第一人称(me,us)~.•Let+第三人称代词(宾格:him,her,it,them)或名词~.Let's go at once.咱们马上动身吧。

Let me try again.让我再试试。

Let Tom go there himself.让汤姆自己去那儿。

注意Let's包括对方,Let us不包括对方。

反意疑问句时最明显。

Let's go,shall we?咱们去吧,怎么样?Let us go,will you?让我们去吧,行吗?(征求对方的意见)Let's say good-by here.我们在此道别吧。

2.否定的祈使句A)句型:•Let's(us,me)+not +动词原形~.Don't let +第三人称代词的宾格或名词+动词原形.Let's not say anything about it.对于这件事,咱们什么也不要说。

Please don't be noisy.请不要大声喧哗。

C)表千万别干某事“Never +动词原形”Never be afraid ! Never do it again !D)表示禁止时,尤其是标语等也可用“No+动名词”来表示。

No smoking.禁止吸烟。

No parking.禁止停车。

句型转换一、祈使句与陈述句的改写1.祈使句=You must …(陈述句)Come here .过来。

=You must come here .你必须过来。

Don't do that again.你一定不可以再那样做了。

2.Please +祈使句=Will you (please) ~?(陈述句)Please help me .请帮帮我。

=Will you (please) help me?你愿意帮我的忙吗?Come here on time ,please .请准时到这儿。

=Will you (please) come here on time ?请你准时到好吗?二、祈使句有时相当一个if引导的条件状语从句。

祈使句:Use your head and you'll find a way.条件句:If you use your head,you'll find a way.≈≈中考链接≈≈1、不要放弃,终有一天你会成功。
