16、ter. （对姊妹要和善。劝告） Watch your steps. （走路小心。警告） Keep off the grass. （勿践草坪。禁止） No parking. （禁止停车禁止） 主语“You”也可以表达出来，使对方听起来觉得柔和些，如： You go and tell him, Chris. （克立斯你去告诉他。） 如果说话时有多人在场,可把主语表示出来,或加呼语,以便指明提出请求或发出命令的对象。 Parents with children go the front! 带孩子的家长到前面去! Mary clean the windows,and you boys wash th

17、e floor! 玛丽擦窗户,你们男孩子洗地板! Come in,everybody! 每个人都进来!有时将主语表示出来是为了加强语气或表示“不高兴”、“厌烦”、“鄙视”等情绪。如： Dont you be late again! 你可别再迟到了! You get out of here! 你给我滚出去! Mind your own business,you! 你少管闲事!2) let型：第一、三人称祈使句 提出建议 Lets go! Let us go home! 让我们回家吧！ Let him be here by 10 oclock让他10点来吧祈使句除用谓语动词表示外,还可用名词、副词

18、、动词短语等表示。如： Help!/ Patience!/ Quickly!/ Hands up!二、祈使句的强调形式及否定形式1.祈使句的强调形式是在整个结构之前加do。如： Do be careful! Do Stop talking! Do give my regards to your parents! 务必一定代我向你父母问好!2.祈使句的否定形式是在整个结构之前加dont或never。如： Dont you be nervous!你不要紧张! Never give up! 决不放弃！ 以let为引导词的祈使句的否定形式通常是在Lets或Let usme后加not。如： Lets n

19、ot waste our time arguing about it! 咱们别浪费时间争论这事了! Lets not say anything about it! 这事咱们谁也别说! 但英式英语也用这样的表达：Dont lets say anything about it.三、祈使句的反意疑问句1祈使句的反意疑问部分为肯定形式,要用shall,will 如： Pass me the book,will you?2Lets表示第一人称的祈使句,反意疑问句为“Shall we?” 如： Lets go for a walk,shall we? Lets forget it,shall we?3Le

20、t me和Let us 表示第二人称的祈使句,反意疑问句为“will you?”。如： Let us go for a walk,will you?4其它行为动词引起的祈使句,无论其陈述部分是否定还是肯定的祈使句,多用“will you?”,表一种客气的语气。如： Listen to me,will you? Dont tell anyone about it,will you?但在肯定的祈使句后有时也用“wont you?”表“提醒对方注意”或表“邀请”。如： Have a cup of coffee,wont you? Come in and take a seat,wont youwil

21、l you?四、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；要不然”。试比较： Hurry up and youll catch the train.

26、祈使句的否定形式,其反意疑问句通常只用will you构成,答案选。3. 分析：由开头的祈使句,其反意疑问句通常用will you构成,答案选。三1. 分析：祈使句的动作通常是指将来发生的动作,所以回答祈使句时,一般用will或wont。因此答案选。2分析：祈使句否定形式的回答含有yes或no时,要注意两点：一是记住“形式一致”,即yes与will保持一致,no与wont保持一致。二是记住“意思相反”,即yes是“不”的意思,no是“是的”的意思。根据这一点,先排除和,又根据第二点和空白处后的题意,答案选,意为“是的,我不会弄出声响”。四1. 分析：根据题意,祈使句与后面的陈述句存在一种顺承关

27、系,此时用连词and来并列,答案为。2. 分析：根据题意,祈使句与其后的陈述句存在一种否定的条件关系,此时连词用or,答案为。3. 分析：本题只要注意到了题中的连词and,答案就清楚了。and起并列作用,前面应该用祈使句,答案选。五 分析：if引导一个条件状语从句,说明后面应该是一个主句,即用祈使句,所以答案选。六分析：空白处前的名词短语表示条件概念,是一个特殊的祈使句,因与后面的句子表示一种顺承关系,连词用and,答案为。七分析：空白处选的话,则此祈使句与后面的陈述句之间没有连词并列,如选或的话,逻辑主语some spelling mistakes又不能执行这个动作,因此,答案只有选。Foc
