Tag questions 反意疑问句 The sports meeting is coming.There are many animals taking part in it, such as deer, squirrel, rabbit,tortoise,...even the shyest snail. Before the sports meeting There is a heated discussion among the animals: Monkey: Last year, the rabbit was the winner, wasn't she? Sheep: Yes, she was. Finally, her effort paid off, didn't it? Tiger: Yes, it did, and I believe she can make it this year, can't she? Sleep: Neither of you will take part in the sports meeting, will you? Monkey: Haha, it's unbelivable, isn't it? 结构：陈述句＋简短疑问句（助动词＼be动词\情态动词＋陈述部分主语的相应代词） 规律：前肯后否, 前否后肯 回答方法:用yes/no来回答 若陈述句中有hardly; never; seldom; little; few; nowhere; nothing等否定词或半否定词, 疑问句部分用肯定式 若陈述句中有带否定前缀的词，疑问句部分仍用否定式 Before the sports meeting 附加疑问句的主语 Look, everyone is preparing for it.

Everything is ready, isn't it? Running is great fun, isn't it? 基本原则：疑问部分的主语应与陈述部分主语一致，且只能是代词。 当陈述部分是there be 句型时， 疑问部分主语仍用there。 当陈述部分主语是somebody, someone, no one, nobody等复合不定代词时，其疑问部分主语用he/they;当陈述部分主语是something, nothing 等复合不定代词时，其疑问部分主语为it. 当陈述部分的主语为动名词、不定式、从句时，疑问部分主语用it. During the sports meeting The sheep has already arrived, he? He has a lot of fans, he? He has a great time at the sports meeting, he? hasn't hasn't/ doesn't doesn't 当have 为助动词时，附加疑问句用同样的助动词。 若表示“所有”，附加疑问句可以用have,也可以用do;但是若陈述句部分用的是have的否定式，附加疑问句用have还是用do,取决于陈述部分的动词形式。 若表示“吃，玩”等意思，附加疑问句要用do。 含have/has附加疑问句 The athletes darted off as soon as they heard the shot from the starting pistol.The rabbit rushed out like the arrow as before. The audience whisper： We should cheer her on, shouldn't we? We must do well in security guarantee, mustn't/ needn't we? We mustn't disturb them, must we?
