4、tever, who, whoever, whom, whose, which. 连接副词：when, where, how, why1. 主语从句作句子主语的从句叫主语从句。主语从句通常由附属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用；连接代词和连接副词在句中既保存自己的疑问含义、又起连接作用，在从句中充当一定的成分。主语从句后的谓语动词一般用单数形式。由疑问词引导的名词性从句， 语序为陈述句语序。例如： That he suddenly

5、 feel ill surprised me a lot.他突然生病让我很吃惊。What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。有时为防止句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。It doesnt matter

6、how we dealt with the problem.我们怎样处理这个问题无关紧要。2. 宾语从句名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。1). 由连接词that引导的宾语从句由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但在以下几种特殊情况，引导宾语从句的连词that 不能省略：a. 当为了强调把that引导的宾语从句可位于句首时，that不能省略。如：That she is a good girl I know. 她是一个好姑娘，我是知道的

7、。That he ever said such a thing I simply dont believe. 我简直不相信他曾说过这样的话。b. 当that从句与动词被其他词或从句隔开时，that一般不宜省略，以免造成语义混乱。如：They told us once again that the situation was serious.他们又一次告诉我们说形势是严重的。The dealer told me how much he was prepared to pay for my car and that I could have the money without delay. 那个商

8、人告诉我他准备出多少钱买我的汽车，并说我会立即收到款。3. 当两个或多个that引导的宾语从句并列使用时，即使省略了第一个从句的引导词that，后面的that也不可省略。如：He said (that) he couldnt tell you right away and that you wouldnt understand. 他说他不能马上告诉你，你是不会理解的。He said (that) it wasnt his business and that the government should do something about it. 他说这不关他的事，而是政府应该对这事想点方法。注

9、意：在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“should+ 动词原形。例如：I insist that she (should) do her work alone. 我坚持要她自己工作。The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。2). 用who，whom, which, whose, what, when, where, why, how

10、, whoever, whatever, whichever等词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。例如：I want to know what he has told you. 我想知道他告诉了你什么。 She always thinks of how she can work well. 她总是在想怎样能把工作做好。She will give whoever needs help a warm support. 凡需要帮助的人，她都会给予热情的支持。3). 用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与i

11、f 在作“是否的意思讲时在以下情况下一般只能用whether，不用if：a. 引导主语从句并在句首时；b. 引导表语从句时；c . 引导从句作介词宾语时；d. 从句后有“or not时；e. 后接动词不定式时。例如： Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。 Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。4). 注意宾语从句中的时态照应，当主句动词是现在时，从句根据自身的句子情况，而使用不同时态

12、。例如：He studies English every day. 从句用一般现在时He studied English last term. 从句用一般过去时I know (that) he will study English next year. 从句用一般将来时He has studied English since 1998. 从句用现在完成时当主句动词是过去时态could, would除外，从句那么要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，那么从句仍用现在时态。例如：The teacher told us that To

13、m had left us for America The teacher told us that Tom is a boy.5). think, believe, imagine, suppose等等动词引起的否认性宾语从句中，要把上述主句中的动词变为否认式。即将从句中的否认形式移到主句中(否认转移)。例如：We dont think you are here. 我们认为你不在这。I dont believe he will do so. 我相信他不会这样做。3. 表语从句在句中作表语的从句叫表语从句。引导表语从句的引导词与引导主语从句的引导词大致一样，表语从句位于系动词后，有时也可用as

14、 if引导。其根本结构为：主语 + 系动词 + 引导词+ 从句。例如：The fact is that we have lost the game. 事实是我们已经输了这场比赛。 That is why he didnt come to the meeting. 那就是他为什么不到会的原因。It looks as if it is going to rain. 看上去天要下雨了。需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如：The reason why he was late was that he missed the train by one mi

15、nute this morning 4. 同位语从句说明其前面的名词的具体内容的从句是同位语从句。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如：The news that we won the game is exciting. 我们赢得这场比赛的消息令人冲动。The thought came to him that Mary h

16、ad probably fallen ill. 他想到可能玛丽生病了。同位语从句和定语从句的区别： 同位语从句所修饰的词是有限的一些抽象名词，而定语从句就没有这种限制。that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。 试比拟下面两个例句: I had no idea that you were herethat引导同位语从句，不能省略Have you got the ideathatthis book gives you of life in ancient Greece？th
