。名词性从句由一个主句和一个或一个以上的从句构成的句子叫复合句。名词性从句在复合句中起名词的作用，它包括主语从句、宾语从句、表语从句、同位语从句四大类，在句中分别用作主语、宾语、表语和同位语。一、引导名词性从句的关联词Athat 连词that本身没有意义，在从句中不担任任何句子成分，在宾语从句中有时可省略。 I hear (that) he has joined the football club. 我听说他已经加入了足球俱乐部。 That light travels in straight line is known to all. 众所周知，光是以直线传播的。 It so happens that I know the man. 碰巧我认识那个。 Is it certain that they will win ？他们一定会赢吗Bwhether和if 连词whether和if本身有意义（解释是否），在从句中不可省略。 1whether可以连接所有的名词性从句，而if只能引导宾语从句及主语从句（在主语从句中不能用在句首）。 I didnt know whether he would attend the concert.（宾语从句，可用if代替whether） The question is whether it is worth trying.（表语从句，不可用if代替whether） Whether she comes or not makes no difference.（主语从句，不可用if代替whether） He must answer the question whether he agrees to it or not.。（同位语从句，不可用if代替whether） 2whether引导的宾语从句可作介的宾语，而if则不能。 It all depends on whether they will support us. (不用if) Ryan was worrying about whether he had hurt her feelings.3.whether后可以接不定式，if 则不能He didnt know whether to get married or to wait.4.whether 直接可与or not 或or no 连用，if 则不能。I wonder whether or not he knew the manager. 5if既可引导状语从句，也可引导宾语从句。如果用if会引起歧义，应避免使用if，而用whether。 Please let me know if you want to join us. 请告诉我你是否想加入我们。（if引导的从句可被看成是宾语从句，if表示是否） Please let me know if you want to join us. 如果你想加入我们的话，请告诉我一声。（if引导的从句可被看成是条件状语从句，if表示如果） Please let me know whether you want t join us. 请告诉我你是否想加入我们。（为避免引起歧义，可用whether表示是否）Cwho, whom, whose, what, which 连接代词who, whom, whose, what, which等在从句中既起连接作用，同时又担当主语、宾语、定语、表语等成分。 No one knows whom he was waiting for. 没人知道他当时在等谁。 We are worrying about what we should do next. 我们正在为下一步该怎么办而烦恼。 Tell me whose house it is. 告诉我这是谁的家。 Let me know which train you will be arriving on. 告诉我你将乘哪列火车到达。 Dwhere, when, how, why 连接副词where, when, how, why等在从句中既是连接词，又作状语。 I dont know where we are going to have the meeting.我不知道我们将在哪儿开会。 She always thinks of how she can work well. 她总是在想怎样能把工作做好。 What I am anxious to know is when we can visit the museum. 我急于知道我们什么时候能参观博物馆。 比较： when引导的时间状语从句和名词性从句中的不同时态。 Please let me know when you arrive. 你到的时候，请告诉我一声。（when引导的是时间状语从句，从句中用一般现在时来表示将来。） Please let me know when you will arrive. 请告诉我你什么时候到。（when引导的是宾语从句，从句中用一般将来时。）Ewhoever, whomever, whatever, whichever, whosever 连接代词whoever = anyone who任何人, 无论谁；whatever =anything that凡是.，无论什么；whichever = anything that无论那一个, 任何一个；whomever = anyone whom （whoever的宾格形式）。 Whoever comes to the club is welcome. 不论谁来参加这个俱乐部都欢迎。 Whatever is worth doing at all is worth doing well.凡是值得做的就值得做好。 They ate whatever they could find on the deserted island. 他们在荒岛找到什么就吃什么。 You may do whatever you will. 你可做任何你想做的事。 Ill take whichever book interests me.我愿买任何让我感兴趣的书。 Whosever book is overdue will be fined. 不管谁的书过期未还都要被罚款。 比较： 连接代词whoever在宾语从句中作主语，whomever作宾语从句中宾语。 You may offer he book to whoever wants it. 你可把这本书给任何想要的人。（此句中不能使用whomever，因为whoever在宾语从句中作wants it的主语） You may offer the book to whomever you like.你可把这本书给任何你喜欢的人。（whomever在宾语从句中作you like的宾语）二、宾语从句在复合句中用作动词宾语或介词宾语的从句叫宾语从句。A. 作动词宾语 He told us（that）he felt ill. Do you know whose dictionary it is ? He has informed me when they are to discuss the work plan. Give a reading list to whoever comes. 给所有来的人一份阅读书目。 注意： doubt（怀疑）的肯定句接if/whether引导的宾语从句，但否定句和疑问句接that引导的宾语从句。 I doubt whether if he will succeed. 我怀疑他是否会成功。 I do not doubt that he can recite the poem. 我相信他能把这首诗背下来。 Do you doubt that he will win 你不相信会获胜吗B作介词的宾语 He was deeply displeased by what had occurred that day. 他对那天发生的事感到很不快。 I am curious as to what he will say. 我很想知道他要说什么。 Your success will largely depend upon what you do and how you do it. They were praised or criticizd according to how they had done their work. He goes to the library every day except when it is raining. 注意： that引导的宾语从句只用在少数介词后，如：except, in, but等。此时，that不能省略。 I know little about him except that he lives downstais. 我对他知之甚少，只知道他住在楼下。 He differed from his classmates in that he devoted his spare time to reading. 他和他的同学们不同的地方在于他把业余时间用在阅读上。C. 作形容词的宾语 I am not sure what I ought to do. 我不能确定我该做什么。 Im afraid (that) you dont understand what I said. 恐怕你没领会我说的意思。 Im suprised (that) I didnt see all that before. 我好奇怪，我以前没见过那一切。D. 用it作形式宾语的情况 1和it作形式主语一样，我们常用it来作形式宾语，把真正的宾语从句放在句末，这种情况尤其出现在带复合宾语的句子中。(think ,consider make, find ) We thought it strange that Xiao Wang did not come yesterday. He has made it clear that he will not give n.。We consider it necessary that he should improve his pronunciation.We found it stange that he has not come yet. 2由于that引导的宾语从句一般不可以直接作介词的宾语，因此当介词后面需要用that从句作宾语时，必须使用it作形式宾语。 You may depend on it that I shall always support you. 你可以放心我会永远支持你的。 Ill see to it that your problem will be dealt with immediately. 我保证你的问题会立即得到处理的。 3在take, hide, see to, insit on, depend on等动词以及一些表示爱憎的动词（enjoy, hate, like, love, dont mind, resent appreciate等）之后，形式宾语it可直接跟宾语从句。 I take it that hes not interested in the book. 我猜想他对这本书不感兴趣。 She hid it that she was married. 她隐瞒了她已婚的事实。 I dont like it when you look at me like that! 我不喜欢那样看我。 4. it不能作由连接代词 whoever, whomever, whosever, whatever, whichever引导的宾语从句的形式宾语。 You may do whatever you will. 你可做任何你想做的事。 Ill take whichever book interests me.我愿买任何让我感兴趣的书。 We are ready to offer help to whoever needs it. 我们乐意帮助任何需要帮助的人。E宾语从句的语序 和其他词性从句一样，宾语从句必须使用陈述语序，不能用疑问语序。 How can I get to the station?Can you tell me? Can you tell me how I can get to the station 你能告诉我怎样去车站吗？ What does he like I wonder I wonder what he likes. 我想知道他喜欢什么。 Where were you born He asked.He asked me where I was born. 他问我出生的地方。 比较： He asked me what was the matter. 他问我出了什么事。(the matter = wrong) He asked me what the matter was. 他问我那是什么物质。F宾语从句中的时态 1在一般情况下，宾语从句中时态要和主句相一致，尤其是主句为过去时态时。 He said that he had lived in Beijing since liberation. 他说自解放以来他一直住在北京。 He made it quite clear that he preferred to learn English. 他明确地说他更喜欢学英语。 2有时，宾语从句中时态也可以和主句不一致。 You cant imagine how they were excited when they won the first place in the game.你无法想象他们获得比赛第一名时是多么的兴奋。 Can you make sure where you have put the gold ring 你能确定你把金戒指放哪儿了吗？ 3客观真理和自然规律的内容在宾语从句中时态保持不变。 Mike asked whether the earth moves around the sun. 迈克问地球是否绕着太阳转。 Columbus proved that the earth is round. 哥伦布证明了地球是圆的。G关于that的省略 一般情况下，宾语从句中的that是可以省略的。但在下列几种情况下，that一般不可省略。1介词后面的that不能省。 Pter is a good student except that he is sometimes careless.彼得是好学生，只是有时粗心。 2并列连词and连接两个或两个以上宾语从句，and前面的that可以省略， and的后面 的 that不能省略。 Everybody could see what happened and that Tom was frightened. My uncle says (that) he has servd here for twenty years and that he is going to retire next month.。 3that引导的宾语从句位于句首时，that不可省略。 That he ever said such a thing I simply dont believe.。 4主句谓语动词与that从句之间有插入语，that不可省略。 He said that, if he could manag it, he would come for dinner. 他说，如果他安排得好的话，他会来吃晚饭的。 5宾语从句中有其他从属连词时，that不能省略。 He told me that if it was necessary they would work all night. 他告诉我，如果需要的话，他们就干个通宵。 H宾语从句的否定转移 在think, consider, believe, suppose, expect, fancy等动词后的宾语从句，如有否定意思，一般要把否定词前移到主句的语上，从句的谓语用肯定的形式。 I dont think he can do it better than me. 我想他不会干得比我好。 I dont believe they have finished their work yet. 我相信他们还未完成他们的工作。 I dont suppose he cares, does he 我想他不会在意的，是吗？ 提示： 在下列情况下，宾语从句不否定转移： 1think等词前有副词和表示强调的do I really expect he wont fail the examination. I do think that he is not fair. 2think等词和其他词构成并列谓语 I think and hope that he wont cheat at cards. 3think等词作为插入语 His decision is not wise, I think. I使用虚拟语气的宾语从句 1在suggest insist, order, demand, request, require, command, propose, desire等表示建议、命令、要求、欲望动词后面的宾语从句中，用虚拟语气，即should +动词原形，should常被省略。 He suggested that we should have a further discussion about the final decision. 他建议我们对最后的决定作进一步讨论。 She insisted that they should show her their passports. 她坚决要求他们向她出示护照。 2在wish后面的宾语从句中需要用虚拟语气，表示与事实相反或难以实现的愿望。 How I wish I had learned more! 我多么希望我以前多学一些啊！ He wishes he would have another chance to go abroad. 他希望能再有一次出国的机会。J含有宾语从句复合句的反意疑问句 反意疑问句一般与主句一致。 He said they were going to help me, didnt he？ 他说过他们要帮我，不是吗？ She told you that the mat was her own work, didnt she 她告诉过你这个垫子是她亲自做的，是吗？ 当主句的主语为第一人称，谓语动词是think, believe, consider, imagine, suppose, hope 等词时，反意疑问句应与宾语从句保持一致。这时特别要注意否定转移的问题。 I suppose youre serious, arent you 我想你是当真的，不是吗？(不可用dont I) I dont suppose hes serious, is he 我想他不是当真的，是吗？ (不可用do I) 提示： 如果主语是第二、第三人称，则疑问句部分与主句一致，且不存在否定转移的问题。 You dont think we can speak English, do you 你认为我们不会说英语，对吗？ He thinks hes got the right answer,doesnt he 他认为自己找到了正确的答案，是吗？三、表语从句表语从句放在连系动词之后，充当复合句中的表语。A可接表语从句的连系动词 可接表语从句的连系动词有be, look, seem, sound, appear,remain等。 China is no longer what she used to be. 今日的中国不再是过去的中国了。 The question remains whether they will be able to help us. 问题还是他们能否帮我们。 It appears that he has a taste for music.看来他对音乐有一定的鉴赏力.
