(2)if 不能用在主语从句中，而是用 whether Whether he left (or not) is unknown (3)当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。 What we need are many more books. 2. 宾语从句 在整个句子中用作宾语的从句叫宾语从句。 He has told me that he will go to Shanghai tomorrow. We must never think (that) we are good in everything while others 欢迎您阅读并下载本文档，本文档来源于互联网整理，如有侵权请联系删除!我们将竭诚为您提供优质的文档！ 4 are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。 it 作形式宾语： 在“主语+ 谓语+ 宾语+ 宾补”的句型中，如果宾语是从句的形式，则必须用 it 做形式宾语，把真正的宾语即宾语从句置于句末。 We found it impossible that the so much work will be finished one day. I think it certain that she will do well in her exam. 注意： （1 ）连词 whether和 if可以互换，但注意下列情况 连词后紧跟 or not时用 whether I want to know whether or not they will come. 作介词宾语是用 whether引导宾语从句 He was interested in whether he saw her there. 连接词后直接加不定式，不能用 if 只能用 whether He doesnt know whether to stay or not. 如果宾语从句是否定时，一般用 if 引导 I care if he will not attend the meeting. 欢迎您阅读并下载本文档，本文档来源于互联网整理，如有侵权请联系删除!我们将竭诚为您提供优质的文档！ 5 （2 ）当主语是 I, we ，主句用 think, believe, suppose, expect, imagine五个动词时，用否定转移 I don t think he will win the game, will he? （3 ）that 在宾语从句常可以省略，但由 and 或 but连接两个或多个宾语从句时，仅可以省略第一个连词 that He said (that) he had eaten nothing but that he wasnt hungry. 注意区别 if 引导的宾语从句和条件状语从句 I dont know if he will come. If he comes, Ill let you know. 3. 表语从句 在整个句子中用作表语的从句叫表语从句。 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。 欢迎您阅读并下载本文档，本文档来源于互联网整理，如有侵权请联系删除!我们将竭诚为您提供优质的文档！ 6 This is because he has been working hard these days. Things are not always as they seem to be 事情并不总是如其表象。 注意：because，as if 和 as though在名词性从句中只能引导表语从句。 4. 同位语从句 在整个句子中用作同位语的从句叫同位语从句。 同位语的含义：在句子中，如果有两个名词，并且后一个名词是对前一个名词的解释说明，它们两个指的是同一个人或同一个物，那么，后面的名词就叫前面名词的同位语。 例如：This is my friend, Tom.（Tom是 my friend 的同位语。）可用于同位语从句的名词有 advice、demand、doubt、fact、hope、thought、 idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等抽象名词。 The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。 I have no idea when he will come back home. 我不知道他什么时候回来。 欢迎您阅读并下载本文档，本文档来源于互联网整理，如有侵权请联系删除!我们将竭诚为您提供优质的文档！ 7 The thought came to him that Mary had probably fallen ill. There is no doubt that he will come. There is doubt whether he will come. Word came that Napoleon would come to inspect them. 同位语从句和定语从句的区别： 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。 试比较下面两个例句: I had no idea that you were here 我不知道你在这里。 （that无含义，that you were here 指的就是 idea，所以是同位语从句，不能省略 that）Have you got the idea（that）this book gives you？ 这本书给了你想法吗？ （that指的是 the idea，that引导定语从句，作宾语，可以省略） 三. 名词性从句中需要区分的情况 1. 疑问词-ever既可以引导名词性从句，也可以引导让步状语从句，而 no matter+疑问词只能引导让步状语从句 欢迎您阅读并下载本文档，本文档来源于互联网整理，如有侵权请联系删除!我们将竭诚为您提供优质的文档！ 8 No matter where I go, my heart is towards China. I believer whatever he says. Whatever he says, I will never believe him. who与 whoever的区别 who是“谁”的意思，表示具有疑问，who相当于 anyone who“无论谁” Whoever leaves the room last ought to turn off the lights. Can you tell me who that gentleman is? 2 当名词性从句缺少主语、宾语或表语时，引导词通常用 what，它相当于all that, anything that或 the thing(s) that。另外，有时具有感叹意义 What we cant get seems better than what we have. Tom thought what a beautiful girl Mary was. 3.注意区分 it 作形式主语的主语从句与强调句 强调句句型 It is/was+被强调部分+that, 去掉 It is/was, that，句子仍然成立。 It is natural that they should have different views. 主语从句 It is only lately that he had had a family himself. 强调句 欢迎您阅读并下载本文档，本文档来源于互联网整理，如有侵权请联系删除!我们将竭诚为您提供优质的文档！ 9 What was it that he wanted? I dont know what it was that he wanted. It was in the hotel where he stayed that we discussed the serious problem 4.注意 it 作形式主语的主语从句和 as 引导非限制性定语从句引导的不同 It is known to all that the earth is round. As is known to all. the earth is round. 四. 连接词 that在名词性从句中可以省略的三种情况 1.it 做形式主语，that引导主语从句时 It is said (that) he has been studying abroad. 据说他一直在国外学习。 2.动词宾语从句中 I think(that) you have much to improve in English.我认为你的英语需要提高的有很多。 3.形容词宾语从句中 I am afraid (that) I will be late.
