5、, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等, 因此根据它在句中不同的语法功能, 名词从句又可分别称为主语从句(Subject Clause)、宾语从句(Object Clause)、表语从句(Predicative Clause) 和同位语从句(Appositive Clause)。名词性从句What he wants to tell us is not clear.

Whether he will come hasnt been decided. = It hasnt been decided whether

8、he will come. 注意: 连词that, whether在从句中不担任句子成分,只起连接作用,不能省略 (注: if不可用来引导主语从句二、用it 作形式主语的结构(1) It is名词从句 It is a fact that 事实是 It is an honor that 非常荣幸 It is common knowledge that是常识(2) It is形容词从句 (多用 should) It is natural that 很自然 It is strange that 奇怪的是(3) It is 不及物动词从句 It seems that 似乎 It happened th

10、ay or not.三、用带-ever的引导词 (如whoever, whatever) 引导的主语从句一般不后置。 Whoever leaves the room last should close the door. Whatever we do must be in the interests of the people.四、it 作形式主语和it引导强调句的比较 it 作形式主语代替主语从句,主要是为了平衡句子结构, 主语从句的连接词有变化。而it引导的强调句那么是对句子某一局部进行强调,无论强调的是什么成分,都可用连词that。被强调局部指人是也可用who/whom。例如:It is

11、 a pity that you didnt go to see the film.It doesnt interest me whether you succeed or not.It is in the morning that the murder took place.It is John that broke the window.五、what与that 在引导主语从句时的区别 what 引导主语从句时在从句中充当句子成分,如主语、宾语、表语, 而that 那么不然,即不担任成分。例如： What you said yesterday is right. That she is st

12、ill alive is a consolation. 句子结构：主句 + 连接词(引导词) + 宾语从句连接词: 附属连词that, whether, if 连接代词 who, whom, whose, which, what 连接副词 where, how, why, when 宾语从句的用法He has got a pen. I thinkI think ( that ) he has got a pen.Where do they study English? Lily asksLily asks where they study English. Will you help me?

13、I askI ask if you will help me.一、连词 (引导词)1. 当宾语从句是陈述句时(包括肯定句和否认句), 连词由that引导, 因为that在从句中不作任何成分, 也没有任何具体意思, 因此在口语或非正式文体中常省略。 He said (that) he would like to see the headmaster.Jane said (that) she wasnt late for the meeting. 2. 当宾语从句是特殊疑问句时, 由特殊疑问词充当连接词, 因为该特殊疑问词(即连接词)在从句中担任一定的句子成分, 具有一定的意义, 所以不可以省略。

14、Do you know what he said just now?I dont remember when we arrived. I asked him where I could get so much money.Please tell me who we have to see.Do you know what time the plane leaves? Mary wrote an article on _ the team had failed to win the game.A. why B. whatC. who D. that I was surprised by her

15、words, which made me recognize_ silly mistakes I had made.A. what B. thatC. how D. which3. 当宾语从句是一般疑问句时,由连词whether或if引导(口语中常用if),因为if/whether翻译成是否,具有一定的意义,所以不能省略。 Lily wanted to know if /whether her grandma liked the handbag . Lets see if /whether we can find out some information about that city . 注

16、意: 关联词只能用whether不能用if 表示 “是否的情况如下： A) 在表语从句和同位语从句中。如： The question is whether the film is worth seeing. The news whether our team has won the match is unknown.B) 在主语从句中，只有用it 作形式主语时, whether和if 都能引导主语从句, 否那么, 也只能用whether。如: Whether we shall attend the meeting hasnt been decided yet. It hasnt been de

17、cided whether (if) we shall attend the meeting.C) 在介词之后。(介词往往可以省略) 如: It all depends (on) whether they will support us.D) 后面直接跟动词不定式时。如： He doesnt know whether to stay or not.E) 后面紧接or not 时。如： We didnt know whether or not she was ready. 关联词if, whether均可使用的情况如下： A) 引导宾语从句。如： I wonder if (whether) th

18、e news is true or not. B) 在 “be+形容词 之后。如： He was not sure whether (if) it is right or wrong. 关联词只能用 whether或if, 不能用that的情况如下： 假设doubt一词作“疑心解接宾语从句时, 主句为肯定句用whether或if, 主句为否认句或疑问句用that。如： I doubt whether he will come soon. I do not doubt that he will come soon.Do you doubt that he will come soon注意: 下面

19、这个例句中doubt的含义为“认为未必可能。 I doubt that he will come.4. 跟在介词后的宾语从句: 宾语从句放在介词后作介词的宾语, 在使用这种结构时不能丢掉介词。 There is no news about whether a new bridge will be built. We are considering of where these trees should be planted.二、语序: 连接词陈述句 合成一个句子：He would be back in an hour. He said He said (that) he would be ba

20、ck in an hour.Do they speak English? We want to know We want to know if/whether they can speak English.What is her name? He asks me He asks me what her name is.三、时态： 如果主句是过去的时态(包括一般过去时, 过去进行时), 那么从句的时态一定要用相对应的过去的某种时态。When will Professor Li give us a talk? We wanted to know We want to know when Profe

21、ssor Li would give us a talk.Jim is a good student. The teacher said The teacher (that) Jim was a good student. Has Mr. Green been in Beijing for five years? He asked He asked if/whether Mr. Green had been in Beijing for five years.四、在think, believe, suppose, expect 等动词之后,宾语从句中谓语的否认常转移到主句的谓语上。 I don

22、t think he will see you. I dont believe he will go. We dont expect he is coming. I dont think he can do it, can he? 注: 此种用法主句的主语必须是第一人称I或we，而且它的反意疑问句的助动词由从句的助动词来定。 I dont think he can do it, can he? I dont think you are right, are you? 在suggest, insist, demand, order, require 等表示建议,命令,要求的动词后,从句的谓语动词

23、要用虚拟语气。如: I insisted that heshoulddo it at once. She suggested that the work (should) be finished at once. 注意:1. 当从句是客观真理,定义,公理,定理时用一般现在时。2. 如果主句的谓语动词是ask时,连词不可能是that;如果主句的谓语动词是say时, 连词用that。1) She says (that) she will leave a message on his desk.2) He asks if I like playing the piano .3. 如果从句中含有or或

24、or not时,只能用whether而不用if。 Do you know whether he is right or not? I dont care whether hell stay here or not. I dont know whether it is going to rain or not.五、在接复合宾语的句子中, 为了保持句子平衡, 用it 作形式宾语,将从句放于句尾, 常接复合宾语的动词有: make, find, see, hear, feel, think. I think it necessary that we take plenty of hot water

25、every day. Ithinkitapitytowastethefood. 1. He asked _ for a violin. (MET1992) A. did I pay how much B. I paid how much C. how much did I pay D. how much I paid2. It is generally considered unwise to give a child _ he or she wants. (NMET1997) A. however B. whatever C. whichever D. whenever 在复合句中用作表语的

26、从句是表语从句, 引导表语从句的关联词与引导主语从句的关联词大致一样,表语从句位于连系动词后,有时用as if引导。其根本结构为:主语 + 系动词 + that从句。 Thats what we should do. Thats why I want to see you. 表语从句的用法 The reason for my absence was that I was ill. 1. be, seem, look等动词后均可跟表语从句： My suggestion is that we should go shopping. It seems that it is going to rain

27、. 2. as if, because 也可引导表语从句。 It looks as if its going to rain. It was because I got up late. 3. 在非正式文体中,引导表语从句的that可以省略。如: The trouble is (that) he is ill. 注意:在表语从句中,当reason做主语时,引导词只能用that,不能用because,如:他迟到的原因是因为他没有赶上早班车。 The reason why he was late was that he didnt catch the early bus. 4. 主句的主语是名词i

28、dea, advice, suggestion, order, request, requirement时, 表语从句应用虚拟语气,即: (should) +v. My suggestion is that we should have a discussion about this matter instead of just setting it aside. What the doctors really doubt is _ my mother will recover from the serious disease soon上海2001年春季招生 A. when B. how C.
