初中英语语法复习 名词性从句,高一（29）班 李莲花,名词性从句 名词性从句，即指具有名词性质的从句。,1）主语从句 2）表语从句 3）宾语从句 4）同位语从句,1、主语从句 作句子主语的从句叫主语从句。 主语从句的时态不受主句时态的影响。,Who cleaned the room is known to all. Whether we will go for an outing tomorrow remains unknown.,That he was late for class made Mr. Li angry. =It made Mr.Li angry that he was late for class.,Section1 主语从句的引导词,1）从属连词 that/whether that 在句中无词义，只起连接作用，位于句首时不能省略。 That he is still alive is a wonder.,2) 连接代词 what, who, which, whatever, whoever等。 What I want to know is this.,3) 连接副词 how, when, where, why等。 Where the party will be held has not yet been announced.,Section2 主语从句与形式主语it,有时为了考虑句子平衡，通常使用形式主语it， 而将真正的主语从句移至句末。 1）that That he didnt come is a pity. =Its a pity (that) he didnt come. 2) 连接代词或连接副词 Whether they would support us was a problem. = It was a problem whether they would support it. 3)对于what 引导的主语从句，通常不用it 作为形式主语。 What we need is money. 如果句子是疑问句，则必须用带形式主语it的结构。如： Is it true that he is the girls father?,2. 表语从句,表语从句就是在复合句中用作表语的从句。 The problem is when we can get a pay rise.,主语,连系动词,表语从句,Section1 表语从句的引导词,1）从属连词 that，whether, as if , as though, because 等。 The fact is that he doesnt really try. The question is whether he is honest. It is because I love you too much. 2) 连接代词 who, what, which, whatever, whoever等。 He has become what he wanted to be ten years ago. 3) 连接副词 how, when, where, why 等。 The problem is how we can find him.,注意：与whether同义的if 通常不用来引导表语从句；同because同义的since, as, for 也不用来引导表语从句。,Section2 That is why 与That is because,1)That is why “这就是的原因；因此” 强调各种原因所造成的后果 why 引导表语从句。用于针对前面已经说明过的原因进行总结。 That is why I cannot agree.(表语从句) = That is the reason why I cannot agree.（定语从句） 2）That is because “这是因为” 强调原因或理由。 He did not see the film last night. That is because he had to help his little sister with her homework.,说明原因,说明原因,说明结果,说明结果,He had seen the film before. That is why he did not see it last night.,3、宾语从句,在句子中起宾语作用的从句叫做宾语从句。 宾语从句在句中作及物动词或介词的宾语。,主语,谓语,宾语从句,I dont know if there will be a bus any more.,Section1 宾语从句的引导词,宾语从句的引导词与主语从句和表语从句的引导词基本相同，通常由从属连词that，whether，if和连接代词、连接副词引导。,We believe that he is honest. I dont know whether hell arrive in time. I dont know who/whom you mean. Hw asked why had to go alone.,Section 2 连词that的省略问题,引导宾语从句的连词that在句中通常可以省略,She said (that) she would come to the meeting. I promise you (that) I will be there.,注意：当两个that 引导的宾语从句由连词and时，即使省略了第一个，也不宜省略第二个，以免造成歧义。 I know (that) he is too old and that he cant do the work.,Section 3 宾语从句与陈述句、疑问句的转换 （直接引语和间接引语）,A:陈述句以that引导的宾语从句。 1. He said : “I am very glad.” He said that he was very glad. B:一般疑问句if/ whether引导的宾从。 2.He said: “ Can you come this afternoon, John?” He asked John if ( whether) he could come that afternoon.

I feel it a pity that I havent been to the get-together.,Section 5 宾语从句与否定转移,当动词think, believe, suppose, expect, imagine, guess, consider 后接一个表示否定意义的宾语从句时，其否定通常转移到主句上。 I dont think that he will leave. I dont believe that it is easy.,4、 同位语从句 同位语从句跟在名词后面，进一步说明该名词的具体内容。,引导同位语从句的名词有：idea, situation thought, fact, evidence, belief, doubt, fear, hope, question, theory, suggestion, proposal, word, thought, truth, possibility, promise, order，news, order, ability等等。,连接词用：when, whether, that （不用which)引导词在句中不充当任何成分。,The news that our class won the match is true. I have no idea when he will be back.,名词性从句考查的几大方面：,（一）、考查连接词 1. _we cant get seems better than _we have.(NMET96) A. What; what B. What; that C. That ;what D. That;that 2.- I drove to Zhuhai for the air show last week. -Is that _you had a few days off? ( NMET99) A. why B when C. what D where,_,_,（二）、考查从句的语序,No one will be sure _in a million years. (MET91) A. what will man look like B what man will look like C. man will look like what D. what look will man like They have no idea at all _(NMET”97) A. where he has gone B. where did he go C. which place had he gone D. where has he gone,_,_,（三）、 考查形式主语（宾语）,1._is a fact that English is being accepted as an international language.(NMET95) A. There B This C. That D. It They make _ clear that they wont go back home for lunch. A. this B that C. he D it,_,_,1. A computer can only do _ you have instructed it to do. (NMET 2001) A. how B. after C. what D. when,名词性从句综合练习,解析：答案为C。本题考查的是名词性从句作宾语的用法。此句的引导词既作连词又在宾语从句中充当一成分，故what最合适。,2. I hate _ when people talk with their mouths full. (NMET 98) A. it B. that C. these D. them,解析：答案为A。本题考查的是形式宾语的用法。题意为“我讨厌人们谈话时嘴里塞满东西”。该空白处没有任何含义，而且已经用了when连接该宾语从句，所以此处只填一个形式宾语it。,3. It is none of your business_ other people t
