祈使句的反意疑問句
1．祈使句的反意疑問部分為肯定形式,要用shall,will.如：
? ? Pass me the book,will you?
2．Let’s表示第一人稱的祈使句,反意疑問句為“Shall we?”.如：
? ? Let’s go for a walk,shall we?
? ? Let’s forget it,shall we?
3．Let me和Let us 表示第二人稱的祈使句,反意疑問句為“will you?”.如：
? ? Let us go for a walk,will you?
4．其它行為動詞引起的祈使句,無論其陳述部分是否定還是肯定的祈使句,多用“will you?”,表一種客氣的語氣.如：
? ? Listen to me,will you?
? ? Don’t tell anyone about it,will you?
但在肯定的祈使句后有時也用“won’t you?”表“提醒對方注意”或表“邀請”.如：
? ? Have a cup of coffee,won’t you?
? ? Come in and take a seat,won’t you／will you?
祈使句用于兩個重要句型中
1．“祈使句+and+表結(jié)果的陳述句”用來敘述肯定的條件.
2．“祈使句+or(else)+表結(jié)果的陳述句”用來敘述否定的條件,or(else)表示“否則；要不然”.試比較：
? ? ? 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．)
祈使句由直接引語變成間接引語
當(dāng)祈使句由直接引語變成間接引語時,其常用結(jié)構(gòu)為“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．)
