It的几个特殊句型
It的特殊句型 一、高考真题 1． (他突然想到) that he had an important conference to attend the next morning.( occur)（11高考78题） 【答案】It occurred to him 【解析】本题考察的是occur引导的句型”it occurs to sb。that（某人突然想到）“根据后面的动词提示”had“，故要用一般过去时. 2.During his last lecture, the scientist_________ (觉得) easier to explain the theory to those with some background knowledge.(find)(09高考73题) 【答案】found it/ found （that）it was ks5u 【解析】考查句型结构。根据提示词find及后面的形容词easier可知此处可使用find it + adj.的结构，it后加be动词变做宾语从句也对，此句时态为一般过去时。 34. _______ _ (我花了) one thousand dollars to buy the painting last week. (cost) (08高考34题) 【答案】It cost me 【解析】考点：it做形式主语（特殊句式）关键词：It cost（★It不用不给分，cost写成co sted 扣0.5分）结构部分：It cost somebody how much money to do something 其它部分：me 二、考点分析 1. It is + 被强调部分+ that ... 该句型是强调句型。将被强调的部分放在前面，其它部分置于that之后。被强调部分可以是主语，宾语，表语或状语。强调的主语如果是人，that可以由who换用。如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。 It is your efforts, not your intelligence, __________(决定) your success. (determine ) It was about 600 years ago that the first clock with a face and an hour hand was made. 2. It is not until + 被强调部分+ that ... 该句型也是强调句型。主要用于强凋时间状语，译成汉语＂直到…才…＂，可以说是not ... until ... 的强调形式。 It was not until she took off her dark glasses that I realized she was a famous film star. = Not until she took off her dark glasses did I realize she was a famous film star. = I didn’t realize she was a famous film star until she took off her dark glasses. 3. It is clear ( obvious, true, possible, certain....) that ..... 该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为＂清楚（显然，真的，肯定）＂是主语从句最常见的一种结构。It is very clear that he’s round and tall like a tree. = That he’s round and tall like a tree is very clear. 4. It is important (necessary, right, strange, natural...) that ... 该句型和上一个同属一个句型。由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。建议记住该句型中的形容词。 It is important that we (should) learn English well. It is necessary that he (should) remember these words. 5. It is said (reported, learned，believed....) that ... 该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为＂据说（据报道，据悉…）＂。 It is said that he has come to Beijing. It is reported that another earth satellite has been put into orbit. 6. It is suggested (ordered ... ) that ...

第11讲：特殊句式和主谓一致
第11讲特殊句式和主谓一致 特殊句式 [深化认知] 一、倒装句 (一)部分倒装 1．将含有否定意义的副词或连词置于句首时引起部分倒装结构。这类词(组)有：never, seldom, rarely, little, few, at no time, by no means, no longer, hardly/scarcely ... when ..., no sooner ... than ..., not only ... but also ..., not until, nowhere, neither ... nor ... 等。 Not until the press reported the pollution did people know why the water supply had been cut off. 直到报纸报道污染情况，人们才知道水供给为什么会被切断。 2．“only＋状语”置于句首时，主句要进行部分倒装。 (2013·全国卷Ⅱ单选)Only by increasing the number of doctors by 50 percent can the patients be treated properly in this hospital. 只有增加50%的医生，病人才能在这家医院得到妥善治疗。 3．so/such ... that ... 结构中的so, such 连同它所修饰的成分共同位于句首表示强调时，主句要用部分倒装。 So suddenly did he catch the disease that the whole family were at a great loss. 他患病突然，全家人全然不知所措。 4．表示前面所说的情况也适合于后者时，用倒装结构“so/ neither/nor＋助动词/系动词/情态动词＋主语”(so表示肯定意义，neither/nor表示否定意义)。 5．as引导的让步状语从句要用倒装结构。即as引导的让步状语从句中必须将表语、状语(形容词、副词、分词)或实义动词提前，构成“形容词/副词/名词/动词/分词＋as＋主语＋谓语的其他部分”的形式。 Hard as they tried，they couldn't make her change her mind. 尽管他们尽力了，但他们还是没能让她改变主意。 (二)全部倒装 1．here, there, now, then, out, in, up, down, away, on the wall, in the room 等表示地点、时间或方位的副词或介词短语置于句首时，句子用全部倒装。 John opened the door. There stood a girl he had never seen before. 约翰打开门，他从来没见过的一位女孩站在那儿。 2．such置于句首时。 Such are the facts; no one can deny them. 这些就是事实，没有人能否定它们。 [名师指津]此句型中such多被认为是表语，所以such后的be动词应与其后真正的主语保持一致。 二、省略句 1．复合句中的省略 在as if, if, though, when, where, while, no matter what, until等引导的从句中，若谓语部分含be动词，而主语又与主句的主语一致或从句主语是it时，从句的主语和谓语中的be动词可以一起省略。 All the photographs in this book, unless (the photographs are)stated otherwise, date from the 1950s. 这本书里所有的照片，除非有说明的，否则，都要追溯到20世纪50 年代。
