1、IT 句型,xxx,根据it 句型的用法特点可归纳为下列几个句型。,一、 考查强调结构的基本形式,原题再现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,答案: B,1. It is (was) + 被强调部分 + that /who. 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
2、，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.,强调结构,考点揭秘,二、 考查一般疑问句的强调结构,原题再现Was _ that I saw last night at the concert?A. it you B. not you C. you D. yourself,答案: A,一般疑问句的强调结构,一般疑问句的强调结构句型为:Is / Was it + 被强调部分 + that / who.?,三
3、、考查特殊疑问句的强调结构,原题再现I have always been honest and straight-forward, and it doesnt matter _ that Im talking to.A. who is it B. who it is C. it is who D. it is whom,答案: B,特殊疑问句的强调结构,特殊疑问句的强调结构句型为: 特殊疑问词( Who / What / When / Where / Why / How.)+ is / was it that.? 例如:Why was it that Li Lei came late agai
4、n?,这类强调结构置于从句中时应使用陈述语序:The question is who it is that we can trust.,四、 考查对not.until.句式的强调,原题再现It was not _ she took off her dark glasses _ I realized she was a famous film star.A. when; that B. until; that C. until; when D. when; then,答案:B,not.until.句式的强调,对not.until.句式的强调有固定的句型, 即It is / was not unt
5、il.that.。,五、 考查强调句型的反意疑问句及回答,原题再现 Wasnt it Dr. Wang who spoke to you just now? _.A. I didnt know he was B. Yes, it was C. No, he wasntD. Yes, he did,答案:B,强调句型的反意疑问句及回答,强调句型的反意疑问句及回答应与It is / was. that.结构保持一致。,六、考查强调结构与其它相似结构的区别,原题再现It was evening _ we reached the little town of Winchester.A. that B.
6、 until C. since D. before,答案: D,六、考查强调结构与其它相似结构的区别,强调结构与其它含有it 的结构非常相似,很容易混淆。 区别的办法是去掉 It is / was. that .结构后,句子依然成立的是强调结构。,2. 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.
7、 = That hes round and tall like a tree is very clear.,3. 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.,4. It is suggested ( ordered, required . ) th
8、at .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.,5. 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
9、 ( should ) happen in your class. It is a pity that he is ill.,6. 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 reported that another man-made satellite has been put into orbit.,7. It is time ( about time , high time ) that .该句型中that 后的从句应该用常用过去时态表示虚
10、拟It is time that children went to bed.,8. 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 ha
11、ve been here.,9. 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，其时态一般是现在时，since 引导的从句通常是一般过去时态，而且是瞬间动词。 It is 5 years since his father died.,10. 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.,11. It be . before .该句型主句中的 it 指
12、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.,12. It happens (seems, looks, appears ) 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, seem 等词是不及物动词 It happened ( so happened
13、) that he met his teacher in the street. 碰巧 It seems that he will be back in a few days看来,13. 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.,14. 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 , (
14、 not any good ) , no use , ( not any use )。 It is no good learning English without speaking English.,15. It doesnt matter whether ( if ) .该句型中whether (if) 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 if they are old.,16. 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

It is kind of you to say so. = You are kind to say so.,17. It is necessary ( for
16、 sb. ) to do sth.该句型与上一个同属一个句型。如果不定式的逻辑主语是由for 引起，主句中的形容词通常是表示重要性，紧迫性，频繁程度，难易，安全等情况的形容词。常见的形容词有： important, necessary, natural It is important for her to come to the party. = It is important that she (should ) come to the party easy, safe, common, normal, hard, difficult, dangerous, unusual, rare, impossible, pleasant 等。,18. 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 looks as if he were ill. （没有生病） It seemed as if he were dying.,
