Unit 1 Wise men in history Date:_______ name:_______ 【语法专项】 一、反意疑问句 (一)含义及构成： 反意疑问句又叫附加疑问句，它表示提问的人对陈述的事实没有把握，需要对方证实反意疑问句由两部分构成：前一部分是一个陈述句，后一部分是一个简短的疑问句。前后两部分在人称、数、时态等方面必须保持一致，如： She often has lunch at school, doesn't she? You don't like sports, do you? (二)使用反意疑问句时要遵循以下三条原则： 1、“前肯后否”或“前否后肯”，如： They are very late for the meeting, aren't they? You can't do it, can you? 2、前后两句主语保持一致，如： 3、前后两句时态保持一致，问句部分的助动词要由陈述句部分的谓语动词决定，如： They will go to town soon, won't they?（不能用don't they?或 aren't they?） He works very hard, doesn't he?（不能用didn't he?或won't he?） (三)反意疑问句的答语： 回答遵循一个原则，那就是不管怎么提问，只要事实是肯定的，就用“Yes，肯定回答”；只要事实是否定的，就用“No，否定回答”。但在前否后肯的反意疑问句中，其答语与汉语翻译不同，Yes要翻译成“不”，No要翻译成“是”。 —You will never forget him, will you? 你永远不会忘记他，是吗? —Yes，I will. 不，我会忘记。 —No，I won't. 是的，我不会忘记。 (四)反意疑问句的特殊用法： 1、反意疑问句的陈述部分为I am……时，问句部分习惯上用aren't I？表示。如： I am a very honest man, aren't I? 2、陈述部分的主语为somebody(someone), anybody(anyone), nobody(no one), everybody(everyone)等表示人的复合不定代词时，问句部分的主语用he或 they，这时问句动词的数应和he或 they一致。如： Someone has taken the seat, hasn't he/ haven't they? 3、陈述部分的主语为something, anything, nothing, everything等表示物的不定代词时，问句部分的主语用it。如： Something is wrong with the computer, isn't it? 4、当陈述部分的主语是指示代词this，that或these，those时，附加疑问句的主语分别用it或they，例如： This/That is a plane, isn't it? 这是一架飞机，是吗？ These/Those are grapes, aren't they? 这些是葡萄，是吗？ 5、陈述部分为There (Here) + be + 主语时，问句部分用动词+there(here)?如： There are two cakes on the plate, aren't there? Here is a story about Mark Twain, isn't here? 6、陈述部分带有little, few, never, hardly, seldom等表示否定意义的词时，问句部分用肯定形式。如： She never tells a lie, does she?（不用doesn't she?） 7、如果陈述部分含有由un-, im-, in-, dis-等否定意义的前缀或后缀时，陈述部分要视为肯定含义，问句部分仍然用否定形式。如： Your father is unhappy, isn't he?（不能用is he?） 8、当陈述部分含有情态动词must时，视情况而定。 (1)当must 作“一定要；必须”讲，反意疑问句须用mustn't或needn't； He must work hard at physics, mustn't he? (2)当must表示推测时，问句部分需根据must后的动词形式决定。如： Tom must be at home, isn't he? You must have got up late this morning, didn't you? You must have made a mistake, haven't you? 9、陈述部分含used to 时，问句部分用didn't或usedn't He used to live in the country, didn't he?/usedn't he? 10、陈述部分含had better 时，问句部分用hadn't +主语？ You'd better tell him about the matter, hadn't you? 11、当陈述部分为含有宾语从句的复合句时 (1)若陈述部分为非第一人称主语+ think(believe, suppose, consider) + that从句时，问句部分的动词和主语与陈述部分主句的动词和主语保持一致。如： ①They all think that English is very important, don't they? （不用isn't it?） ②He didn't think that the news was true, did he? （不用wasn't/ was it?） (2)若陈述部分为I(We) don't think(believe, suppose, consider)+ that从句时，从句为否定意义，问句部分的动词和主语仍与that从句保持一致且用肯定式。如： ①I don't think that you can do it, can you? （不用do I?） ②We don't believe that the news is true, is it? （不用do we?） 12、若陈述部分为主语+said( told, reported, asked……) + that从句时，问句部分的动词和主语与陈述部分主句的动词和主语保持一致。如： ①They said that you had finished your work, didn't they? （不用hadn't you） ②Kate told you that she would go there, didn't she? （不用wouldn't she?） 13、当陈述部分为祈使句时 (1)不管是肯定还是否定，问句一般用“will you?”，陈述部分是肯定祈使句时，问句部分一般用will you形式表示请求，用won't you形式表示委婉请求或邀请；陈述部分为否定祈使句时，问句部分一般用will you?如： Please open the window, will you?(won't you?)
