4、在复合句中的作用相当于名词，因此这四种从句统称为名词性从句。1. 主语从句（The Subject Clause）主语从句在复合句中作主句的主语。当主语从句是陈述句时，引导词通常用 that, that在句中不可省略，如主语从句是疑问句，则根据句子的意思选择相应的引导词，如who, what, which, when, where, how ,why 等。注意：有时为了避免头重脚轻，常用 it 作形式主语置于句首，而把主语从句置于句末。(1) That these old languages are now threatened and may disappear is a serious m

6、语从句是陈述句时，引导词通常用 that, that 在句中可省略，如宾语从句是疑问句，则根据句子的意思选择相应的引导词，如 who, what, which, when, where, how ,why 等。注意：当宾语从句后面有宾语补主语时，则需要用 it 作形式宾语，而将宾语从句放于句末，其基本结构为：主语+谓语+it+ 宾补+宾语从句(1) They realize that it is of great value to keep their original language.(2) Many parents dont understand why their children l
7、ike to try new things and be different.(3) Can you imagine what will happen next？(4) They are careful about what they eat and exercise regularly.(5) Do you think it necessary that we must master at least a foreign language?3. 表语从句（The Predicative Clause）表语从句在复合句中作主句的表语。当表语从句是陈述句时，引导词通常用 that, that在句
8、中不可省略，如主语从句是疑问句，则根据句子的意思选择相应的引导词，如who, what, which, when, where, how ,why 等。(1) This is how Henry solved the problem.(2) The question is why we must do it.(3) What many people are worried about is whether we will be able to build a better future.4. 同位语从句（The Appositive Clause）同位语从句在句中起同位语的作用。它一般跟在某些
9、名词（如 fact, idea, news, promise，truth, word, proposal, suggestion, answer, decision 等）的后面，用于说明或解释前面的名词的内容。引导同位语从句的词有 that, that 在句中不可省略；少数情况下也可用连接副词 how, when, where 等。(1) The fact that Great Britain consists of three countries is still unknown to many people.(2) The idea that England stands for Fish

12、signs that people here are living a better life. ( )8. He has made it clear that he wouldnt come back to the company. ( )三、名词性从句的考点及难点1. 引导词 that 和 what 的用法区别that 在引导名词性从句时，只起连接作用，不充当任何成分；what 在引导名词性从句中不仅起连接作用，还在从句中充当主语，宾语和表语。The trouble is that they have eaten too much junk food.The trouble is what
13、 they have eaten is junk food.考例 1：People in Chongqing are proud of _ they have achieved in the past ten years.A. that B. what C. how D. which考例 2：_ we are badly in need of money is not a secret.A. that B. what C. how D. which2. 引导词 if 和 whether 的用法和区别If 和 whether 作“是否”解，引导宾语从句时可互换，但在下面的情况只能用whether
14、：作介词的宾语时；引导主语从句、表语从句和同位语从句时。改错：It depends on if the weather is suitable for us to do it.The question is if he will lend us a hand in solving the problem.3. 名词性从句的语序名词性从句要用陈述语序代替疑问语序。改错：Have you got any idea where has he gone?Do you know how many students are there in this class?4. 名词性从句的时态当主句是过去时态，从
15、句（特别是宾语从句）通常也要用过去的某种时态。改错：The teacher asked me How many English words I have learned.She asked if the government will take measures to bring down the prices.5. 虚拟语气在名词性从句中的使用在表示请求、建议、要求、命令等意义的名词性从句中，从句常用“should +动词原形”表示虚拟语气，should 一般可以省略。考例 1：Mother ordered that we _ the homework first.A. must do B.
16、 can do C. should do D. would do 6. who/ whoever, what/ whatever 等的用法和区别一般来说，what/ who 等含特指意义，而 what/ whatever 等含泛指意义，意为“无论什么/ 无论谁” 。考例 1：Could I speak to _ is in charge of International Sales please? （2009 全国I）A. who B. what C. whoever D. whatever考例 2：It is a matter of _ would take the position.A.
17、who B. whoever C. whom D. whomever考例 3：_ wants to stay in a hotel has to pay their own way.A. Anyone B. The one C. Whoever D. Who7. 同位语从句和定语从句的区别同位语从句和定语从句通常都跟在某一名词后面，都可用 that, which, where, when 来引导。 值得注意的是同位语从句中的 that 不充当任何成分，而定语从句中的 that 要充当从句的主语或宾语；定语从句的引导词 where，when 与前面的名词概念一致，而同位语从句中的 where，w
18、hen 与前面的名词概念上不一致。考例 1：The news _ the plan would take off on time made us happy.A. what B. that C. which D. it考例 2：The news _ was about the accident made us sad.A. what B. which D. it D. when考例 3：They raised the question _we were able to get so much money.A. where B. that C. about D. in which考例 4：The lab building _ we used to do experiments stands empty now.A. where B. what C. that D. about which练习：1. 英语周报第 9 期和第 12 期第三版的语法练习；学习的艺术第2. 翻译练习：（1）
