附加疑问句又称为反意疑问句，是附加在陈述句后的简短问句,对陈述句所叙述的事实或观点提出疑问。 1、 附加疑问句的结构、组成及功能 1.结构:陈述部分＋附加疑问部分(助动词/be动词/情态动词＋陈述部分主语的相应代词) 2.规律:陈述部分是肯定形式,附加疑问部分用否定形式;陈述部分是否定形式,附加疑问部分用肯定形式。助动词和人称前后一致。【前肯后否，前否后肯】 3.功能：对说话人说的句子的反问，有加强语气、请求进一步的确定的意味 二、否定附加疑问句的回答 不管【前肯后否，前否后肯】，直接【根据实际情况回答】 【前肯后否，照实回答前面】或将句子转化成一般疑问句再去回答 —lt's a beautiful day, isn't it?今天天气很好，不是吗? 【Is it a beautiful day】—Yes, it is. 是的,它是。 —That sounds interesting, doesn't it?听起来很有趣，不是吗? 【Does it sound interesting?】—Sure, it does. 当然，确实如此。 —He wants to go, doesn’t he?——他想去,不是吗? 【Does he want to go?】—No, he doesn’t.——不,他不想去。 【前肯后否，照实回答后面】 —You aren’t a student, are you?你不是学生,是吗? 【Are you a student?】—Yes, I am.不,我是。/No,I’m not.是的,我不是。 —It's not a real sport, is it? 【Is it a real sport?】—Yes, it is.不，它是。/No, it is.是的，它不是。 2.当陈述部分为否定式,附加疑问部分为肯定式时,要根据事实来回答, 事实是肯定的用Yes;Yes译为“不” 事实是否定的用No;No译为“是的”。 三、附加疑问句的几种特殊情况 1.there、不定代词与指示代词做主语 1）There was an old stadium in front of our school, wasn’t there? There are some ducks swimming in the river, aren’t there? 陈述句是存在句There be句型时，简短问句为be的适当形式+ there? 2）Someone is waiting for you at the school gate, isn’t he? Nobody want to go with you, do they? Everyone likes apples， doesn’t he? Nothing is better than this method, is it? 表示人的不定代词（如everyone/everybody/someone/somebody/no one等）时，简短问句的主语:复数they或单数he。 表示物的不定代词（如nothing/everything/anything等）时，简短问句的主语用it代指。 3）This isn’ t your first time here, is it？ That is a new car, isn’t it? These are credit cards, aren’t they? Those aren’t my friends, are they? 指示代词this/that，简短问句的主语用it； 指示代词these/those，简短问句的主语用they。 祈使句的反义疑问句：let’s 和let us 1）Look at me please, will/won’ t you? Open the window, will/ won’t /would you? Don’ t eat in class, will you? 肯定祈使，疑问用will/would/won’t you,【will you表请求；won’t you表邀请，劝说】 否定祈使，疑问用will/can you; 2）Let’ s play a game, shall we? Let’ s go hiking, shall we? Let us go to the park, will you? let’s （咱们）开头的用shall we, let us/me（我们/我）开头的用will you. 含否定的含义和否定的前缀 1）He seldom contacts his family, does he? There is little milk in the
