语法：反意疑问句一、基本用法与结构反意疑问句由“陈述句+简略疑问句”两部分组成，第一部分提出一种看法，第二部分用来质疑或表示证实。

陈述部分与疑问部分的动词时态和动词性质应保持一致，而且肯定和否定形式彼此相反，即陈述部分为肯定式时，疑问部分用否定式，陈述部分为否定式时，疑问部分用肯定式：He likes English, doesn’t he? 他喜欢英语，是吗？He doesn’t like English, does he? 他不喜欢英语，是吗？【注】1. 若陈述部分含有seldom, hardly, never, few, nothing等否定词或半否定词，其疑问部分要用肯式：He has few friends here, has he? 他在这儿几乎没什么朋友，是吗？She said nothing, did she? 她什么也没说，是不是？2. 若陈述部分含有带否定前缀的词，疑问部分仍用否定式：It is unfair, isn’t it? 这不公平，不是吗?It is impossible, isn’t it? 那是不可能的，是吗?二、反意疑问句的主语问题1. 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：Mary is a nurse, isn’t she? 玛丽是护士，对吗？2. 当陈述部分为there be句型时，疑问部分仍用there作“主语”：There was nothing in the room, was there? 房间里什么也没有，是吗？3. 当陈述部分的主语是指示代词时，疑问部分用it, they等代词：That is a new car, isn’t it? 这是一辆新汽车，是吗?4. 当陈述部分的主语是复合不定代词时，若陈述部分的主语为somebody, someone, everyone, everybody, no one, nobody等复合不定代词，其反意疑问句的主语在正式文体中用he，在口语或非正式文体中通常用they：Nobody was late, were they? 没有一个人迟到，是吗?5.当陈述部分的主语是something, anything, nothing, everything等复合不定代词时，其反意疑问句的主语要用it：Everything is ready, isn’t it? 一切都准备好了吗？Nothing is important, is it? 没有什么重要的，不是吗?三、陈述部分有动词have的反意疑问句1. 当have 为助动词时，其反意疑问句沿用同样的助动词：He has already left, hasn’t he? 他已经离开了，是吗?2. 当have 为实意动词时，要分两种情况：① 若表示“所有”，反意疑问句可以用have，也可以用do：He has a lot of friends here, hasn’t [doesn’t] he? 他在这儿有许多朋友，是吗？但是若陈述部分用的是have的否定式，反意疑问句用have 还是用do，取决于陈述部分的动词形式：He hasn’t any money, has he? 他没有钱，是吗?He doesn’t have any money, does he? 他没有钱，是吗?① 若表示“吃”、“玩”等意思，反意疑问句要用do：He has supper at 5, doesn’t he? 他5点吃晚餐，是吗?He had a good time at the party, didn’t he? 他在晚会上玩得很开心，是吗?3. 当用于have to时，通常也有两种可能：若表示经常性的行为，则多用加助动词do的形式；若表示特定的行为，则多用have：He often has to get up early, doesn’t he? 他经常要早起，是吗?He has to go to bed late tonight, hasn’t he? 他今晚要迟睡，是吗?四、含情态动词的反意疑问句1. 基本原则：在通常情况下，当陈述部分含有情态动词时，疑问部分会重复前面同样的情态动词：He can speak English, can’t he？他会说英语，是吗？We shouldn’t go, should we? 我们不应该去，对不对？2. 当陈述部分含有must时，要分两种情况：① 若must表示“必须”或“有必要”，疑问部分用mustn’t 或needn’t：You must leave at once, mustn’t [needn’t] you? 你必须(有必要)马上离开，是吗?但是若陈述部分有mustn’t表示禁止，疑问部分要must：You mustn’t laugh, must you? 你不准笑，知道吗?① 若must表示推测，疑问部分不能用must，而应根据must后的动词结构采用相应的动词形式：He must be tired, isn’t he? 他一定累了，是吗?五、陈述部分为祈使句的反意疑问句1. 基本原则：若陈述部分为祈使句，疑问部分通常用will you：Please help us, will you? 请帮帮我们，好吗？Come with us, will you? 同我们一起去，好吗？Don’t forget to post the letter, will you? 请别忘了寄信。
