2015年高考冲刺：英语反义疑问句的用法

　　11. 在由“祈使句+附加疑问句”构成的反义疑问句中，附加的疑问部分一般用will you, won't you, wouldyou等，有时也可用can you, can't you, why don’t you,could you等。如：

　　Don't open the door, will you?

　　Give me some cigarettes, can you?

　　Take a rest, why don't you?

　　但是，以let's开头的祈使句，附加疑问部分用shall we;以let us开头的祈使句，如果含义是allow us，不包括听话人在内，疑问部分用will you。如：

　　Let's have a basketball match this afternoon, shall we?

　　Let us go out for a rest, will you?

　　12. 当陈述部分带有情态动词must表示“必须”时，疑问部分用mustn't。如：

　　You must work hard next term, mustn't you?

　　I must answer the letter, mustn't I?

　　但若表推测这层含义时，不能用must，而要根据陈述部分的不定式结构(即must之后的动词)以及含义采用相应的动词形式。如：

　　You must have made a mistake, haven't you?

　　They must have seen the film last week, didn't they?

　　He must be in the library, isn't he?

　　13. 当陈述部分含有情态动词used to时，疑问部分可用usedn't或didn't。如：

　　The old man used to smoke, didn't he?或usedn't he?

　　Tom used to live here, usedn't he?或didn't he?

　　14. 当陈述部分带有情态动词ought to时，疑问部分用oughtn't或shouldn't。如：

　　He ought to know the answer, oughtn't he?

　　We ought to read this book, oughtn't we?或shouldn't we?

　　15. 当陈述部分含有had better时，疑问部分用had。

　　如：You'd better finish your homework now, hadn't you?

　　16. 感叹句后的附加疑问句的谓语动词需用be的现在时，且常用否定形式。如：

　　What a clever boy, isn't he?

　　What a lovely day, isn't it?

　　17. 陈述句子中的主语为动词不定式短语、动名词短语或其他短语时，疑问部分的主语通常用it。如：

　　Learning how to repair motors takes a long time, doesn't it?

　　Between six and seven will suit you, won't it?

　　Where to hold the meeting has not been decided, has it?

　　18. 在口语和非正式文体中，为了加强语气，只是表示某种惊奇、怀疑、反感、讽刺等感情而并不是为了寻求回答，这时前后两部分的肯定、否定是一致的。如：

　　Oh, he is a writer, is he?

　　You'll not go, won't you?

　　19. 陈述句中的谓语动词是wish，表示愿望时用may，且用肯定形式。如：

　　I wish to have a chance to learn English, may I?

　　20. 当陈述部分带有表示“所有”含义的动词have(has)时，疑问部分既可用have形式，也可用do形式。如：

　　You have a new bike, haven't you(或don't you)?

　　She doesn't have any money in her pocket, does she?
