(完整版)英语祈使句讲法与练习和答案祈使句一、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。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）No parking. (禁止停车。-禁止）二、祈使句的否定形式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 !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 not 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“Shallwe？”。如：Lets go for a walk，shall we？Lets forget it，shall we?3Let me 和 Let us 表示第二人称的祈使句，反意疑问句为“willyou?”。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 youwill 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。 (If you hurryup,youll catch thetrain)Hurry up,or youll miss the train(If you don t hurry up，youll miss the train）（一）用括号内所给词的适当形式填空1 Its an important meeting。_ (not be） late。2_ (look） out!A car is coming！3_ (not make) any noise！ The baby is sleeping。4Lets _(not say) anything about it.5_ （not let） the baby cry.6_ （read） aloud,please。7_ （not talk) with your classmate in the class.(二）选择题1Her doctor said:”_ work so hard”A stopB DontC cantD No2Sindy，_ to be here at 8 oclock。Ais sureB is sure thatC will be sureD be sure3_ him the secret，will you？A Dont tell B Not to tell C Not telling D No telling4Please _ look outside,look at the blackboard.AnotB dontC arentD cant5John，read the text for us,_ ?Adoes heB will heC do youD will you6Lets do it at once，_ ?A shall weB will youC do weD do you7Let us do it at once，_ ？A shall weB will youC do weD do you8_ in bed, Its bad for your eyes。A Not to readB Dont readC Dont to readD Not read9_ smoking！A DontB NoC Dont toD Be not10.
