反义疑问句用法总结

反义疑问句用法总结一.反意疑问句的定义反意疑问句（The Disjunctive Questions ）是疑问句的一种，它对陈述部分的事实提出相反的疑问，形式上是个省略句，附在陈述部分之后，并用逗号与陈述部分隔开（主语一般用相应的代词；有时这种问句并没有反意疑问句的意味，而是提出一个事实上听话人承认的问题。所以，人们统称为附加疑问句（Tag Questions ）。附加疑问句主要是由“陈述句 + 附加疑问”构成，附加疑问部分的动词一般要与陈述部分的动词相对应，附加疑问部分的主语要与陈述部分的主语相对应，如果陈述部分的主语是名词词组，则附加疑问部分用相应的代词表示。二.附加疑问句的类型附加疑问句的类型为：陈述句 + 反意附加疑问。该类型又可以分为以下两种情况阐述： ①当陈述句为肯定式时，附加疑问句用否定形式，即肯定的陈述句+否定的附加疑问句。 It's very hot today, isn't it ? Yes, it is . 今天天气很热，是不是？是的，很热。 That clock is slow ,isn't it? Yes, it is. 这钟是缓慢的，不是吗？是的，它是。 You want to get your TV set back , don't you ? Yes , I do. 你想您的电视机回来，不是吗？是的，我是这样想的。 ②当陈述句用否定式时，附加疑问句用肯定形式，即否定的陈述句+肯定的附加疑问句。 It isn't very hot today, is it ? 今天不是很热，是吗？ That clock isn't slow ,is it ? 这钟不是缓慢的，是吗？注意这一类型的附加疑问句的回答，不管问题的提法如何，若事实是肯定的，就要用yes，事实是否定的，就要用no，这与汉语不一样，应特别注意。 She isn't a teacher , is she? 她不是教师，是吗？Yes , she is. 不，她是。 No, she isn't .是的，她不是。三.附加疑问句的构成 1.当陈述部分的主语是everybody, everyone ,someone, no one, nobody, somebody 等指人的合成词时，附加疑问部分的主语在正式语体中通常用he,在非正式文体中则往往用they。 Nobody likes to lose money , does he? 没有人愿意赔钱，那么他呢？ Everyone enjoyed the party, didn't they /he ? 每个人都很喜欢这个舞会，他们不是吗？ 2.当陈述部分的主语是everything ,anything, something, nothing 等指物的合成词时，附加疑问部分的主语只能用 it。 Nothing is difficult , is it ? 没什么难的事情，不是吗？ Everything seems all right , doesn't it ? 所有的事情都好了，不是吗？ 3.当陈述部分是there 引起的句时，附加疑问部分的主语也用there。（1）、there be 句型时，疑问部分的主语用there, There are some books on the table, aren’t there? (2)、当以表示“地点”的there 引导时，要用陈述句真实主语的相应代词形式作疑问部分的主语，常有这两个句型：There live…… There stand…… There stand two trees on the hill, don’t they? There lived a poor old man in the woods, didn’t he? 4.当陈述部分含有seldom , hardly, scarely, no, not,never, rarely,few, little, nothing, nobody , nowhere 等否定词或半否定词，附加疑问部分采用肯定形式。 Nobody phoned while I was out ,did they ? 当我在外面的时候没有人来电话，是吗？ Few people know him ,do they ? 几乎没有人认识他，是吗？ He has never been to Beijing ,has he? 他从来没有去过北京，是吗？ 5.当陈述部分含有un- ,in- ,im-, il-, ir-, dis-等否定前缀或less等否定后缀构成的派生词时，附加疑问则用否定形式。

it_is---_that强调句用法1

It is……that强调句用法当需要强调句中的主语、宾语、状语时，我们常用“It is(was)+被强调部分+that(who)”这种句型，使用此句型时，应注意以下几点。 1.一般情况用It is(was)……that…如： He read three books in the library yesterday. 我们分别可以强调主语、宾语、地点状语和时间状语。如： It was he who(that)read three books in the library yesterday. (强调主语) It was three books that he read in the library yesterday.(强调宾语) It was in the library that he read three books yesterday. (强调时间状语) 2.当被强调部分指人时，可用that，也可用who；指物时，只用that,如： It was Tom who(that)I met last week. It is a new bike that his brother wants to buy. 3.强调状语时，只用that,不用when、where.如： It is at 5 o'clock that the train will arrive. 4.被强调的部分是主语时，注意句子的谓语动词和被强调的主语保持一致。如：It is he who is late. It is they that were late. 5.一般疑问句的强调句为:Is (was) it + that…? 特殊疑问句为：特殊疑问词+ is (was) it +that…?结构。如： Was it ten years ago that his father died?（他的父亲是十年前去世的吗？）When is it that you will set off?（你到底什么时候出发？） 6.注意在强调句的疑问句型中，强调标志that/who后只能使用陈述语序。比较：Was it by plane that did he come back ?(×) Was it by plane that he came back? (√) When was it that the Second World War broke out? (√) When was it that did the Second World War break out ?(×) 7.强调时间状语和地点状语时与定语从句的区别： It was in 1921 that our Party was founded.(强调句式) It was 1921 when our Party was founded.(定语从句) 即：强调时间或地点时有介词置于其前时，则连接词用that。其前面应有介词而被省去时，则用连接词when（时间）或where(地点)。又如： It was on the farm that we practised planting crops. It was the farm where we learned a lot . 1
