初中英语祈使句讲解及练习

初中英语――祈使句 祈使句指的是表示命令、请求、建议或劝告的句子。其主语you常省略,谓语动词用原形,句末用感叹号或句号,读降调。 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 + n./adj. Be a good boy!要做一个好孩子!Be careful! = Look out! = Take care!小心/当心!(3)Let +宾语+动词原形+其它成分 Let me help you.让我来帮你。Let’s go to school together.咱们一起上学去吧。 2.否定的祈使句 (1) Don“t +动词原形 Don“t stand up.别站起来。 Don“t be careless.别大意。 Don“t let them play with fire.别让他们玩火。 (2)Let型的否定式有两种:“Don“t + let +宾语+动词原形+其它成分”和“L et +宾语+ not +动词原形+其它成分”。 Don“t let him go. / Let him not go.别让他走。 Let them not play with fire.别让他们玩火。 (3)no开头,用来表示禁止性的祈使句。 No smoking!禁止吸烟!No fishing!禁止钓鱼!

3.祈使句的强调形式,通常在肯定祈使句式前加上助动词Do。 例如:Do shut up!快住口! 4.祈使句的回答祈使句的动作通常是表示将来发生的动作,所以回答祈使句时,大凡用will或won’t。 在回答具有否定意义的祈使句时,要注意两点: 1)形式一致(即Yes与will保持一致;No与won’t保持一致) 2)意思相反(即Yes是“不”的意思;No是“是”的意思)。 在回答时,要注意分析上下文语境中所提供的条件。 如:---Don’t go out, please. It’s raining heavily outside.请不要出去。外面雨下得很大。 ---- Yes, I will. I have to meet my brother at the airport.不行,我得去机场接我弟弟。 5.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won“t you。 Please open the door, will/ won’t 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。 Don“t be late again, will you?别再迟到了,行不行? (3)以let“s开头的祈使句反意疑问句反问部分用shall we。 Let“s turn on the TV, shall we?我们把电视打开,好吗? <特别注意>只有以let“s开头的祈使句的反意疑问句的反问部分才用shallwe,而letus开头的祈使句的反意疑问句的反问部分应为will you或 won“tyou.如:Let us stay here, will/ won“tyou?请(你)让我们留在这好吗?

英语祈使句详解(664)

英语祈使句详解 1. 祈使句的概念 表示请求、命令、建议、祝愿、邀请或要求的句子叫祈使句。用于祈使句 句首的动词总是用原形,不能用其他形式。如: Shut the door! 把门关上! Have a cup of coffee! 喝杯咖啡吧! Let them go by train. 叫他们坐火车去吧。 祈使句的主语通常为第二人称(you),但一般都被省略,只有在特殊的情况下才把主语(you)补充出来。如: You be quiet! 你安静! You go and tell him, Chris. 克立斯,你去告诉他。 You wait here for a moment. 你在这儿等一会儿。 有时祈使句的主语也可以是everybody, somebody, anybody, nobody等不定代词。如: Stand up, everybody! 全体起立! Nobody move. 任何人都不许动。 2. 祈使句表示强调 为了加强祈使句的语气,我们通常是在祈使句的动词原形前加上助动词d 务必”等。如: o,此时通常译为“一定”“ Do be careful. 务必要小心。 Do have some more tea. 一定再喝点茶。 Do let me go. 一定让我去。 副词never和always有时可用于祈使句句首,表示强调。如: Never do that again. 再不要这样做了。 Always look in the mirror before starting to drive. 一定要先看看反光镜再开车。 3. 祈使句的否定式 构成祈使句否定式的方法很简单,那就是在动词原形前加don’t——不管祈使句所用的动词为什么性质动词,情况都是一样。如: Open the window. 把窗户打开。 →Don’t open the window. 别把窗户打开。 Come next Monday. 下周星期一来。

英语祈使句详解 1.祈使句的概念 表示请求、命令、建议、祝愿、邀请或要求的句子叫祈使句。用于祈使句句首的动词总是用原形,不能用其他形式。如: Shut the door! 把门关上! Have a cup of coffee! 喝杯咖啡吧! Let them go by train. 叫他们坐火车去吧。 祈使句的主语通常为第二人称(you),但一般都被省略,只有在特殊的情况下才把主语(you)补充出来。如:You be quiet! 你安静! You go and tell him, Chris. 克立斯,你去告诉他。 You wait here for a moment. 你在这儿等一会儿。 有时祈使句的主语也可以是everybody, somebody, anybody, nobody等不定代词。如: Stand up, everybody! 全体起立!Nobody move. 任何人都不许动。 2.祈使句表示强调 为了加强祈使句的语气,我们通常是在祈使句的动词原形前加上助动词do,此时通常译为“一定”“务必”等。如:Do be careful. 务必要小心。Do let me go. 一定让我去。 副词never和always有时可用于祈使句句首,表示强调。如: Never do that again. 再不要这样做了。 Always look in the mirror before starting to drive. 一定要先看看反光镜再开车。 3.祈使句的否定式 构成祈使句否定式的方法很简单,那就是在动词原形前加don’t——不管祈使句所用的动词为什么性质动词,情况都是一样。如: Open the window. 把窗户打开。→Don’t open the window. 别把窗户打开。Come next Monday. 下周星期一来。 对于以let us或let’s开头的祈使句,其否定式通常是在不定式之前放一个not。如: Let’s tell him the truth. 我们把实情告诉他吧。→Let s not tell him the truth. 我们不要把实情告诉他。 但在日常口语中,我们也可以把don’t放在let’s之前。如:Let’s don’t tell him the truth. 我们不要把实情告诉他) 4. 祈使句与连用please 为了使祈使句的语气变得委婉,我们可以在祈使句的句首或句末加上please——若加在句首,其后不用逗号;若加在句末,则通常会在please前加一个逗号。如: Step this way, please. 请这边走。Please type your letter. 请把你的信打出来。 Open the window, please. 请把窗户打开。 如果是否定祈使句,则通常将please加在don’t之前。如: Please don’t get angry. 请不要生气。 5.祈使句的时间概念 祈使句所表示的时间总是指将来,所以与它连用的句子原则上要用将来时态来与它呼应。如: Give me a hand, will you? 帮我一个忙,好吗? 由于give me a hand表示隐含将来意义,所以句中的will you 不能改为do you。 Try again and you will succeed. 你再试就会成功。由于句中的try again隐含将来意义,所以句中用了you will succeed,而不是you succeed。 Don’t do that again or you’ll be in trouble. 别再干那个了,否则你会有麻烦。句中的don’t do that again指的是以后不要再干那事了,由于隐含有将来意义,所以句中用了you’ll be in trouble,而没有用you are in trouble。6. 祈使句的省略 一般说来,祈使句总是要以动词原形开头,但是,在某些特殊情况下,我们可以只用一个词或短语来表示祈使句的意义。如: Just a few please. 请给几个就行了。 A little more slowly please. 再慢一点。 A pound of butter. 给我一磅黄油。Two teas and four coffees, please. 请来两杯茶和四杯咖啡。
