例如:—You won’t be away for long, will you? 你不会离开太久,是吗?—Yes, I will. 不,我会离开很久。

(事实是会离开很久)—No, I won’t. 是的,我不会离开很久。

(事实是不会离开很久)Let’s go home, shall we? 回家吧,好吗?(包括说话人)Let me have a try, will you? 让我试一试,行吗?(不包括说话人)注意判别:'s是has和is与主语的缩略形式,'d是would和had与主语的缩略形式。

例如:He’s going to play basketball, isn’t he?She’s been to Beijing many times, hasn’t she?You’d better tell him about it at once, hadn’t you?They’d like something delicious to eat, wouldn’t they?5. 祈使句表示请求、命令、劝告、建议、号召等的句子,常省略主语you,句首用动词原形。

①肯定祈使句:动词原形+其他成分,如:Listen to me carefully.②否定祈使句:Don’t (never)+动词原形+其他成分,如:Don’t be late for class next time.Don’t do that again.Never leave today’s work for tomorrow.③Let引导的祈使句Let +第一、三人称+(not)动词原形,表示建议做某事,如:Let me try again.Let Jack wait a minute.④祈使句的强调语气Do+动词原形+其他成分,如:Do come back at once!Do be careful.⑤祈使句的特殊形式:1) No+名词/动名词+其他2) None+of介词短语3) 祈使句+and+简单句,表示“如果……就……”4) 祈使句+or+简单句,表示“……否则……”5) 在祈使句后面,加一个问句,使语气更加委婉例句:No smoking! 请勿吸烟!None of your nonsense!Go down the street, and you’ll see a cinema. 沿着这条街走,你就会看到一家电影院。

Be quick, or we’ll be late. 快点,否则我们要迟到了。

Don’t tell anyone, will you? 不要告诉任何人,好吗?6. 感叹句表达喜、怒、哀、乐等强烈感情的句子叫作感叹句。
