1、1江西省信丰中学高考英语 名词从句讲练复习概念：起名词作用的从句叫名词从句。它和名词一样，在句中可充当主语，表语，宾语和同位语。名词从句包括主语从句，表语从句，宾语从句和同位语从句。 名词从句的引导词通常有： 1. 连词 that, whether, if. 2. 连接代词 what, whatever, who, whoever, whose, which 3. 连接副词 when, where, how, why I. 主语从句 主语从句在从句中作主语，主语从句可以位于句首，但常见的主语从句多放在句末，句首则用形式主语 it。 例如： 1. That the earth is round
2、is true. = It is true that the earth is round. 2. Whether he will come hasnt been decided. = It hasnt been decided whether 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。并且whether 引导主语从句时不能用 if 代替。 3. Who let out the news remained unknown. = It remained unknown who let out the news. 4. Ho
3、w this happened is still a question. 5. It is not clear when we will start. 6. Why he didnt come here is not clear to anyone. = It is not clear to anyone why he didnt come here. 7. Which is right isnt known to us. 注意：who, which, how, when, where, why 在所引导的主语从句中可担任主语，宾语，状语，不能省略。可以用形式主语 it 引导。 8. What
4、 he said at the meeting is important. 9. Whoever leaves the office should tell me. 10. Whenever the Olympic Games will be held in Beijing is not known yet. 注意：who, whom, which, what 等可以和 ever 构成合成词，引导主语从句和宾语从句。此类主语从句不能用 it 引导，引导词在句中担任句子成分，不能省略。 另外，有的“It 主语从句”已成为固定结构。如： a. It is +名词从句 It is a pity th
5、at we cant go. b. It is 形容词从句 It is clear that Tom has returned. 2c. It is 过去分词从句 It is said / reported / believed / known II. 表语从句 在复合句中用作表语的从句是表语从句。 Thats what we should do. Thats why I want to see you. 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 t
6、hat we should go shopping. It seems that it is going to rain. 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 作主语时，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 wh
7、y he was late was that he didnt catch the early bus. III. 宾语从句 在复合句中用作宾语的从句是宾语从句 1. 作动词宾语 I dont know what I was thinking of. I wonder if I might give you a necklace. I expect （that）I shall be back on Sunday. 在口语中，that 引导宾语从句时常常省略。但两个 that 从句并列时后边的 that 一般不省略。 若有补语，则宾语从句要放到补语之后，在宾补前用形式宾语 it. He does
8、nt want it to be known that he is going away. I consider it necessary that he should do it again. 在 think, believe, suppose, expect 等动词之后，宾语从句中谓语的否定常转移到主句的谓语上。如： I dont 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
9、 称 I 或 we. 而且它的反意疑问句的助动词由从句的3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，从句的谓语动词要用虚拟语气。如： I insisted that he （should）do it at once. She suggested that the work （should）be finished at once. 2. 作介词宾语 The teach
10、er is satisfied with what I said. 3. 作 afraid, glad, certain, sure 等形容词的宾语。 Im afraid that I will be late. Im glad that you passed the exam. IV. 同位语从句 如果担任同位语的是个句子，则这个句子是同 位语从句。同位语从句表示先行名词的具体内容，能跟同位语从句的名词常见的有 news, idea, belief, doubt, fact, rumour, question, order, hope, thought, reply, problem, re
11、ason 等。 引导同位语从句常用连词 that，它在句中不担任句子成分，没有词意。除 that 外，还有whether, when, where, who, what, which, why, how 等。可以引导同位语从句。 The rumour that there will be an earthquake soon spread all over the area. They have no hope that he will recover. I have no idea where they have gone. 同位语从句与先行名词有时也可以分开。 Suddenly the t
12、hought came to me that he could go blind. （3）同位语从句与先行名词是等同关系，一个具体，一个抽象，两者常可以转述为主表关系，而定语从句与先行词是修饰与被修饰关系。比较： The news that our team won the game is true. （_） The news is that our team won the game. （_ ） The news that you have heard isnt true. （_） 4Whether 与 if 在名词从句中的用法 Whether 可以用于所有的名词从句中，if 只用于宾语从句
13、中，两者都不能省略。 1. 在引导宾语从句（动词宾语从句）时，whether 和 if 可以互换，但如果出现 or not 则只能用 whether. I dont know whether / if I can come. = I dont know whether I can come or not. 2. 介词的宾语从句只能用 whether 引导。 We worried about whether he was in good health or not. 3. 引导主语从句，表语从句，同位语从句时都用 whether. The question is whether you can
14、do it yourself. （_） Whether they will win is all the same to me. （_） The question whether he should come himself or send another one hasnt been decided. （_） 4. 和动词不定式连接时，只能用 whether. I havent decided whether to go there or not. 随堂练习 .用适当连词填空 1. _ you need is more practice. 2. _ we need more equipmen
