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 have some more tea. 一定再喝点茶。 Do

英语祈使句讲解及练习
祈使句精讲及练习
一、祈使句(Imperative Sentence)
定义:用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句,祈使句最常用于表达命令,因此在学校文法中也常称为命令句。
祈使句因对象(即主语)是第二人称,所以通常都省略。祈使句的动词都为一般现在时,句末则使用句号来表示结束。例: go and wash your hands. (去洗你的手。;命令) Be quiet, please.(Please be quiet.) (请安静。;请求) Be kind to our sister. (对姊妹要和善。;劝告) Watch your steps. (走路小心。;警告)
Look out!Danger! (小心!危险!;强烈警告,已如感叹句) Keep off the grass. (勿践草坪。;禁止) No parking. (禁止停车。;禁止)
祈使句也常把主语You表达出来,使对方听起来觉得柔和些, 例如:
You go and tell him, Chris. (克立斯你去告诉他。) 二、相关口令
祈使句无主语, 主语you常
