规律：前肯后否, 前否后肯，助动词和人称前后一致。如：Yu are frm Australia, aren’t yu?He desn’t live in Beijing, des he?回答方法:用yes / n来回答，事实是肯定的用yes，反之用n。如： He isn’t a student, is he?N, he isn’t.
Grammar summary
一、反意疑问句主语要与前面陈述句主语保持一致。1. 陈述句主语是that，this，thse，these，反意疑问句的主语要用it或they。如： This is Tm’s textbk, isn’t it? These are yur bks, aren’t they?2. 陈述句主语是表示人的不定代词，如anyne，smene，n ne，everybdy，nbdy，smebdy等，反意疑问句的主语通常用they。如： Everyne knws that writer, dn’t they?
3.陈述句主语是表示物的不定代词，如anything，nthing，smething，everything等，反意疑问句的主语用it。如： Nthing in the wrld is difficult, is it?4. 陈述句的主语是非谓语动词或主语从句，反意疑问句的主语用it。如： Smking is nt allwed here, is it? What he lacks is curage, isn’t it?
5. Let’s与Let us / me后的反意疑问句的主语不同。如： Let’s start early in the mrning, shall we? Let us / me knw yur new address, will yu?6. 陈述句如果是there be句型，反意疑问句的主语用there。如： There is little water left, is there?
二、反意疑问句的助动词要与陈述句的助动词保持一致。1. 在含I am的陈述句之后，反意疑问句的助动词用aren’t。如： I am suppsed t be here, aren’t I?2. 陈述句谓语动词为have t时，反意疑问句用d作助动词。当陈述句中have作“有”讲时，反意疑问句中既可用have作助动词也可用助动词d。如： We have t take a test, dn’t we? He has a gd memry, hasn’t / desn’t he?
3. 陈述句的谓语动词含有used t时，反意疑问句多用did作助动词。如： She used t live in Lndn, didn’t she?4. 陈述句中有情态动词must时： 1) must表“一定，准是”，反意疑问句中助动词要与must后动词照应。 如：Yu must be very excited, aren’t yu? Yu must have waited here fr a lng time, haven’t yu? 2) must表“必须”，反意疑问句中的助动词用mustn’t。如： Yu must leave right nw, mustn’t yu? 3) mustn’t表“禁止”，反意疑问句中的助动词用must或may。如： Yu mustn’t walk n grass, must/may yu?
三、反意疑问句用肯定还是否定 陈述句是肯定句，反意疑问句用否定； 陈述句是否定句，反意疑问句用肯定。 陈述句含有表示否定或部分否定意义的单词，如nt，n，never， nne，little，seldm，hardly，few，nwhere，nthing等，看成否定句，反意疑问句用肯定。如： Mary seldm ges t the cinema, des she?
四、陈述句是主从复合句或其它句子时1. 陈述句是主从复合句时，反意疑问句常重复复合句中主句的主语。主句中如果有I think/believe/suppse这样的主谓结构时，反意疑问句重复从句主语。如： Yu never tld us why yu didn’t pass the exam, did yu? I dn’t think she cares, des she?2. 陈述句是并列句时，反意疑问句与后一个分句保持一致。如： They were absent yesterday, but Mary wasn’t, was she?
3. 祈使句的反意疑问句常用will或can作助动词。祈使句为肯定句时， 反意疑问句常用will / wn’t / can / can’t yu；祈使句为否定句，反意疑问句则常用will / can yu。如： Please clse the windw, will / wn’t / can / can’t yu?
