I didnt know he was,B. Yes, it was,C. No, he wasnt,D. 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. until,C. sinceD. 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.,=,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 . ) 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.,5.

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.,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.,1,0.

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 ) that he met his teacher in the street.,碰巧,It seems that he will be back in a few days,看来,1,3. 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.,1,4. 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.,1,5. 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 adj. to do sth.,It is kind of you to say so.,=,You are kind to say so.,1,7.

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.,19.
