Unit 1 名词性从句课件

名词性从句01什么是名词性从句定义：在英语的句子结构中，本来该由名词充当的主语、宾语、表语和同位语，由一个句子来充当,这个句子就叫名词性从句。名词在句子当中一般可以作什么成分?The boy is li Ming.主语表语Mr. Liang , a 24-year-old boy, teaches us English .主语同位语宾语名词性从句类型名词性从句主语从句 ( The Subject Clause)宾语从句 ( The Object Clause) 表语从句 ( The Predicative Clause)同位语从句 ( The Appositive Clause)从句类型名词性从句 形容词性从句 ( 定语从句) 副词性从句 ( 状语从句)02怎么辨认名词性从句主语从句在句中做------ 宾语从句在句中做------表语从句在句中做------ 同位语从句在句中----- 主语宾语表语同位语1. That he will come is certain. 2. I know that he will come.3. The truth is that I have been there. 4. The fact that she was late surprised us.It is certain that he will come. 看从句出现的位置和充当的成分同位语和定语从句的辨析Do you know the fact that he stole the car?Do you know the fact that they were talking about?注意：1. 如果是定语从句，它的从句肯定是不完整的，关系词肯定在句中充当成分的；而同位语从句中的that只起连接作用。 2. 定语从句是对先行词起修饰作用，而同位语从句则解释说明先行词的具体内容。(同从)(定从)请判断出下列的句子属于哪种从句What I want to do is taking a bath.The news that they won the game spread the whole school.I don’t think he is an honest boy.The fact is that he stole the car.Do you know the fact that he stole the car?Do you know the man who is standing over there?It is said that they won the game.(主从)(同位语从句)(宾从)(表从)(同位语从句)(定从)(主从)03单击此处添加副标题内容引导词的分类名词性从句的引导词既可以有含义，又可以在句子当中充当成分。eg. Who I respect most is my math teacher. The person who I respect most is my math teacher.引导词包括 that，if/whether，who，whom，whose，what, which, when, where, why, how, whoever, whomever, whatever, whichever注意： 名词性从句的引导词和定从，状从引导词有很多相同的，所以要求大家首先学会区分不同类型的从句。……的人 宾语1、That we will realize our dreams in the future is certain .2、The fact is that Beijing will hold 29th Olympic Games this year.3、I know that well begun is half done . 4、He heard the news that Liuxiang set a new world record . “that”---无词义、不作成分、起连接作用（主语从句）（表语从句）（宾语从句）（同位语从句）引导词that的几点注意：1. 主语从句的that放在句首看着很别扭，但必须有2. it做形式主语的句子，后方也是主语从句。 That we will realize our dreams in the future is certain . It is certain that we will realize our dreams in the future .3. 表语从句的that不可以省略。 作文总爱犯这样的错 eg.The reason why I respect him most is he works very hard.4. 宾语从句that可有可无，改错中不要专门去添加that eg.I know he works very hard5. 同位语从句的引导词 理论上都可以用，但实际使用中还是以that为主1、Whether she will come back on time depends on weather . 2、The problem is whether you could give us some valuable advice . 3、I asked him whether/if he could do me a favor .4、Could you tell me the question whether English is useful for us now. “if/whether”---“是否”、不作成分、起连接作用（主语从句）（表语从句）（宾语从句）（同位语从句）if 只能引导两种名词性从句：宾语从句(介词后方的宾从不行）、不放于句首的主语从句。eg. We’re worried about whether he is safe.2. whether四种从句均可以引导。3. whether or not 连在一起可以，但if不可以。而“whether…or not = if …or not”If与whether的区别：eg. I don’t know whether/if he is well or not. I don’t know whether or not he is well.1. Who will go to the college is still uncertain. 2. The problem is who we can find to replace her.3. I know who you are.who,译为“谁” ，在名词性从句中 作主、宾、表I know whom you respect most.whom 译为“谁” ，在名词性从句中 作宾I don't know whose book it is . whose 译为“谁的” ，在名词性从句中 作 定语what 译为“1. 什么 2. 的sth.” ，在名词性从句中 作主、宾、表、定1. What embarrassed me is that I didn’t recognize him at first sight.2. I don’t know what you are talking about.3. He is not what he was three years ago.4. I gave him what help I could. which 在名词性从句中 作主、宾、表、定 译为：哪一个He wanted to know which was on the table.He asked me which I liked best.I don't know which her choice is. I don't know which bike belongs to my father.whatever,whichever,whoever,whomever 在名词性从句中 作主、宾、表、定 译为：无论……Whoever could solve the problem will be rewarded . Whomever you will meet in the meeting is excellent . What we should do is whatever is worth doing. You could choose whichever book you want . when,where,how,why在名词性从句中 作状语When the meeting will begin isn’t decided now .Where I could buy the book is uncertain now .What surprised me was why they failed again .How the thief stole the bike is still a mystery .主语从句特殊性主语从句的that放在句首看着很别扭，但必须有it做形式主语的句子，后方也是主语从句。 That we will realize our dreams in the future is certain . It is certain that we will realize our dreams in the future .3. 单个句子作主语，谓语用单数。 That he will succeed is certain . 表语从句特殊性表语从句不是只能跟在be动词后方，还有look,appear,seem,remain 表从引导词除了常规的词以外，还有 as, as if=as though, becauseHe was late this morning. That was because he was caught in a traffic jam.All this was over twenty years ago, but it’s as if it was only yesterday. He looked just as he had looked ten years before. 宾语从句特殊性介词后方的宾语从句一般不用that，如果用，则不可以省略that She is not satisfied with what she has achieved. Mary always thinks of how she can do more for the class. He wrote a letter of thanks to who helped him. (任何一个)2. it作形式宾语时，真正的宾语从句不可以省略that We think it our duty that we should help others.3. be+adj.这一结构后方的句子也叫宾语从句 I’m afraid (that ) I’ll be late. We were surprised that he lost the game.同位语从句特殊性同位语从句和被解释说明的名词有隔裂现象 He got the news from Mary that the sports meeting was put off. Word came that Napoleon would come and inspect his grand army.04单击此处添加副标题内容做题思路名词性从句做题思路1. 找到从句部分，判断是什么从句2. 确定是名词性从句后，判断从句是否缺成分。3. 如果不缺成分，根据翻译考虑that，if/whether, when/where/why/how4. 如果缺成分，根据翻译考虑what(ever)， which(ever)， who(ever)， whom(ever)， whose 由于名词性从句引导词与定语从句，状语从句引导词重复的较多，容易形成混杂，因此同学们需要注意训练区分各类从句判断以下句子是什么从句She is the girl that talked to you yesterday. The book which I bought last week was lost.The fact is that he stole the car.Mr Liu is the person whom you talked about on the bus.
