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?2．Let’s表示第一人称的祈使句,反意疑问句为“Shall we?”.如： Let’s go for a walk,shall we? Let’s forget it,shall we?3．Let 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? Don’t tell anyone about it,will you?但在肯定的祈使句后有时也用“won’t you?”表“提醒对方注意”或表“邀请”.如： Have a cup of coffee,won’t you? Come in and take a seat,won’t you／will you?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 you’ll catch the train.(＝If you hurry up,you’ll catch the train．) Hurry up,or you’ll miss the train．(＝If you don’t hurry up,you’ll miss the train．)祈使句由直接引语变成间接引语
当祈使句由直接引语变成间接引语时,其常用结构为“ask／request／tell／order sb(not)to do sth”.如：“Speak loudly,please!” the teacher said to me．(＝The teacher asked me to speak loudly．) “Don’t smoke in the meeting room!” he said to Tom．(＝He told Tom not to smoke in the meeting room．)
