這件事,好嗎? 但在肯定的祈使句后有時(shí)也用“ won’t you?”,表示提醒對(duì)方注意或邀請(qǐng)。如: Have a cup of coffee, won’t you? 來一杯咖啡,好嗎? ( 4)“祈使句 +and+表結(jié)果的陳述句”用來敘述肯定的條件;“祈使句 +or ( else) +表結(jié)果的陳述句”用來敘述否定的條件, or ( else)意為“否則;要不然”。如: ① Hurry up and you’ll catch the train.(= If you hurry up, you’ll catch the train.) ② Hurry up, or you’ll miss the train.(= If you don’t hurry up, you’ll miss the train.) ( 5)當(dāng)祈使句由直接引語變成間接引語時(shí),其常用結(jié)構(gòu)為: ask/ request/ tell/ order sb. ( not) to do sth.。如: ①“ Speak loudly, please!” the teacher said to me. → The teacher asked me to speak loudly. ②“ Don’t smoke in the meeting room!” he said to Tom. → He told Tom not to smoke in the meeting room.
