it句型及练习(附答案).doc

It句型诠释及练习含 it 的句型几乎年年高考考到，现根据其用法特点可归纳为下列句型。 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 was about 600 years ago that the first clock with a face and an hour hand was made. It was they that (who ) cleaned the classroom yesterday. It was in the street that I met her father. 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 didnt 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 hes round and tall like a tree. = That hes 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) 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 man-made satellite has been put into orbit6. It is suggested ( ordered, required . ) that . 该句型和上一个同属一个句型。主句中的过去分词是表示请求，建议，命令等词时，that 后的从句要用虚拟语气（should + 动词原形），should 可以省。常译为“ 据建议；有命令）”。 It is suggested that the meeting ( should ) be put off. It was ordered that we ( should ) arrive there in two hours. 7. It is a pity ( a shame . ) that . 该句型中，that 后的从句一般用虚拟语气（should + 动词原形），should 可省去表示出乎意料，常译为“竟然”。没有这种意义时，则不用虚拟语气。 It is a pity that such a thing ( should ) happen in your class. 这种事竟然发生在你们班上，真是遗憾！ It is a pity that he is ill. 他生病了，真遗憾！ 8. It is time ( about time , high time ) that . 该句型中that 后的从句应该用虚拟语气，值得注意的是 常用过去时态表示虚拟 有时也用should + 动词原形，should 不能省。常译为“是（正是）的时侯”。 It is time that children should go to bed. = It is time that children went to bed. 9. It is the first ( second ) time that 该句型要和上一个句型区别开来。该句型中的 that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中 that 可以省去；it 有时用 this 替换，常译为“是第一（二）次”。 It is the first time I have been here. = This is the first time I have been here. 10. It is since . 该句型主要用作处理瞬间动词的完成时，又要和表示一段时间的时间状语连用的问题。主句中是时间作表语，其时态是现在时或完成时，since 引导的从句通常是一般过去时态，而且是瞬间动词。如果主句是一般过去时，从句则用过去完成时。 It is ( has been ) 5 years since his father died. 11. It is . when . 该句型中的 when 引导的是一个时间状语从句，主句中的 it 指时间，表语由具体的时间充当。常译为“当的时候，是”。 It was 5 oclock when he came here. 12. It be . before . 该句型主句中的 it 指时间, 主句中的时态常是将来一般时或过去时两种时态主句中的表语多是long, not long , 3 days , 2 weeks 等表示时间段的词或短语。常译为“之后”。 It was 3 days before he went to Beijing. It will be not long before he finishes his job. 13. It happens that. 该句型中it是形式主语，that 引导的是主语从句，主句中的happen是不及物动词 It happened ( so happened ) that he met his teacher in the street. 碰巧 14. It takes sb. to do sth. 该句型中的不定式是真正的主语，it是形式主语，句型中的直接宾语是时间。常译为“做要花费某人”。 It took thousands of people many years to build the Great Wall. 15. It is no good (use ) doing sth. 该句型中的真正主语是动名词短语，主句中的表语可以是no good , ( not any good ) , no use , ( not any use )。 It is no good learning English without speaking English. 16. It doesnt matter whether. 该句型中whether 引导的从句是真正主语，该句型常译为“不论（是否） 没关系。 It doesnt matter whether they are old (or not). 17. It is kind ( of sb. ) to do sth. 该句型中的不定式短语是真正主语，如果不定式的逻辑主语是由 of 引起，主句中的形容词必须是能表示逻辑主语特征的形容词。常见的有: bad, brave, careless, clever, cruel, foolish, good (好心的), honest, horrible, kind, lazy, modest, naughty, nice (有教养的), polite, rude, silly, stupid, wise, wrong (错误的)等。 这个句型可以改写为：sb. is kind to do sth. It is kind of you to say so. = You are kind to say so. 18. It is necessary ( for sb. ) to do sth. 该句型与上一个同属一个句型。不定式的逻辑主语由for 引起，形容词通常表示重要性，紧迫性，频繁程度，难易，安全等情况。常见的形容词有： important, necessary, natural easy, safe, common, normal, hard, difficult, dangerous, unusual, impossible, pleasant 等。 如：It is important for her to come to the party. = It is important that she (should ) come to the party 19. It seems/appears that 看来 It seems/appears that he will be back in a few days. It looks ( seems ) as if . 该句型中it 无意义。 as if 引导一个状语从句。常译为，“看起来好象 如果与事实不相符合，则用虚拟语气 It looks as if he is ill.（真的病了） It seemed as if he were dying.(虚拟语气)20. We think it important to learn a foreign language. 该句型中的it 作形式宾语。为了记忆方便我们可称该句型为：【 6123结构 】 6 指主句中常用的动词：think, believe, make, find, consider, feel ； 1 指的是形式宾语it ； 2 指的是宾补的两种形式：形容词或名词 ； 3 指的是真正宾语的三种形式：不定式短语，动名词短语或that 引导的宾语从句。 We think it our duty to clean our classroom every day.

What; that; that B. That; that; whatC. What; what; that D. What; that; what 简析：本题结构复杂，乍看难以理清，请看下面两句：It is determination that has made Peter what he is today.对划线部分提问What is it that has made Peter what he is today?对照原题，则答案为D。 依此为据扩展开来可为： 4How is it that she turned down our help? 什么原因使得？ 5Where was it that you met Tom yesterday? 究竟在哪？ 6When was it that you met him in the park? 究竟何时？ 7When and where was it that you got to know Mary? 究竟在何时何地？ 8Who was it that that came up with the bright idea? 究竟是谁？ 9Which book is it that you want to buy? 究竟是哪一本书？ 10Whose umbrella was it that you took away? 到底是谁的伞？三、 强调句型的反意疑问句形式句式特征为：It is/was+被强调部分+that，isnt / wasnt it？ 11It was Alice and her boyfriend who sent the old man to the hospital, _?A. do they B. didnt they C. wasnt it D. was it 简析：答案C. 此种情况下疑问句中的主语应与强调句型中的主语it保持一致，不能和被强调部分中的名词或代词保持一致，并要遵守“前肯定后否定”的原则。四、强调句型的感叹句形式。 句式特征为：what/ how it is (that) +主语+谓语！ 12What a beautiful picture it is (that) you have drawn! 13How beautiful it is (that) your daughter is!五、强调句型的“让步含义”。句式特征为：含有“让步含义”的强调句型在翻译成汉语时要注意“反译”。 14It is a wise father that knows his own child.再英明的父亲也不会理解他自己的子女。（莎士比亚名言） 15It is a wise man that never makes mistakes.再聪明的人也会犯错误。六、在强调句型中考察主谓一致与比较结构。 在强调句型中，有时也考察用rather than，not but等连接的平行对比结构，此时既要注重比较结构，又要注意主谓一致，属于较复杂的句式。句式特征为： It is/was notbutthat ; 不是而是（that后的动词与but后的名词或代词保持一致） It is /was not that ; 是而不是（that后的动词应与not前的名词或代词保持一致） It is/was rather than that ;是而不是 ( that后的动词应与rather than前的名词或代词保持一致) 16It is not help but obstacles that make a man. 简析：本句译为“使人成才的，不是助力，而是阻力”。注意obstacles和make形成主谓一致关系。 17Personally I think it is the sales manager, rather than the sales girls, _ to blame.A. is B. that is C. are D. who are 简析：此句被强调部分中的the sales manager，通过rather than与the sales girls形成比较结构，再考虑到主谓一致的原则，应选B。 18(NMET 2000, 24) It is the ability to do the job _ matters not where you come from or what you are.A. one B. that C. what D. it 简析：本题答案选B。在本题中被强调部分the ability to do the job 与 not where you come from or what you are形成比较结构，the ability to do the job与matters形成主谓一致关系。当然本题还可说成：It is the ability to do the job not where you come from or what you are that matters. 但这样就显得句子重心不稳，结构不合理。 19It is the prevention of disease rather than its successful treatment that has led to the rapid increase of the worlds population. 简析：本句中被强调部分为对比结构，含义为“导致世界人口快速增长的原因是对疾病的预防而非对疾病的成功治疗。”当然has led to的主语应是the prevention of disease。七、强调句型中的be动词和情态动词的结合。句式特征: It may be+ 被强调部分+ that It must have been+被强调部分+ that Would/ C
