考点祈使句 高考频度：★★★☆☆难易程度：★★★★☆ 1. （2017·新课标卷I·短文改错）I The instructor kept repeating the word（改为 words）, “Speed up!” “Slow down!” “Turning left!” 【答案】Turning改为Turn 【解析】分析语境可知教练的话“加速”，“减速”，“左转”都是祈使句，根据前文“Speed up!” “Slow down!”也可以看得出来。祈使句应该用动词原形，故将Turning改为Turn。 2. （2016·新课标卷Ⅱ·语法填空）It could be anything —gardening, cooking, music, sports —but whatever it is, __________ (make) sure it’s a relief from daily stress rather than another thing to worry about. 【答案】make 3.Always _____________ in mind that your main task is to get this company running smoothly. A. to keep B. to have kept C. keep D. have kept 【答案】C 【解析】考查祈使句。这是一个完整的句子，而that引导的是宾语从句，因此只能是祈使句。故选C。句意：永远记住，你的主要任务就是让这个公司平稳运行。 【名师点睛】祈使句表请求、命令、叮嘱、邀请、劝告等。祈使句分为第二人称祈使句及第—、三人称祈使句两大类。祈使句用于两个重要句型中：①＂祈使句+and+表结果的陈述句＂用来叙述肯定的条件；②＂祈使句+or(else)+表结果的陈述句＂用来叙述否定的条件，or(else)表示＂否则＂；句首以动词原形开头。从本题的成分来判断，可以看出是考查祈使句。

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。
祈使句的构成和用法 一.祈使句的句式特征 祈使句常常是表达说话人对对方的劝告、叮嘱、请求或命令等。因此，祈使句中一般没有主语，但根据其句意，实际上是省略了主语you。祈使句句末用感叹号或句号，朗读时，常用降调。在表达请求或劝告时，在祈使句前或句末可加上please，以使句子的语气更加缓和或客气。祈使句一般没有时态的变化，也不能与情态动词连用。例如： Keep off the grass!勿踩草地！ Put the boxes in the small room.把那些盒子放到那个小房间里。 二.祈使句的肯定句式 祈使句的肯定句式一般分为以下三种类型： 1.行为动词原形＋其它成分。例如： Make sentences after the model.根据例句造句。 2. Be动词＋其它成分(形容词、名词或介词短语等)。例如： Be careful when crossing the street.过马路时要小心。 3. Let＋宾语＋动词原形＋其它成分。例如： Let him go back now.让他现在回去吧。 三.祈使句的否定句式 祈使句的否定句式，通常情况下在句首加上Don’t或Never，一般分为以下四种类型： 1.在祈使句的肯定句式前加Don’t，构成『Don’t＋行为动词原形＋其它成分』。例如： Don’t say that again! 别再那样说了！ 2.在Be动词引起的肯定祈使句前加Don’t，构成『Don’t be＋其它成分(形容词、名词或介词短语等)』。 例如：Don’t be careless.不要粗心。 注意：在这种句型中be不能省略；否定副词not不可置于be之后。 3. Let引起的祈使句的否定形式有两种： (1)Let开头的祈使句，如果后面跟第一、第三人称名词或代词的宾格，可在Let
