名词性从句

1. 名词性从句 Noun Clauses

2. 名词从句 在复合句中起名词作用的从句叫名词从句 (Noun Clauses）。名词从句的功能相当于 名词词组, 它在复合句中能担任主语、宾语、 表语、同位语、介词宾语等，因此根据它在 句中不同的语法功能，名词从句又可分别称为 主语从句、宾语从句、表语从句和同位语从句。

3. Subject(主语) Object(宾语) Predicative (表语) Appositive (同位语) Noun Clauses Clause

4. 1.You knowthat I am a teacher of English. 2. That I am a teacher of English is known to you all . 3. It is known to you all that I am a teacher of English. 4. The fact that I am a teacher of English is known to you all. 5. I am worried about whether you can do well in the exam. 6. What I am worried about is whether you can do well in the exam.

Object Clause whether you can do well in the exam. What I am worried about Subject Clause Predicative Clause

6. 名词性从句考点归纳 一、名词性从句的语序———陈述语序 他是怎么成功的仍然是个谜。How was he successful is still a puzzle. ( )How he was successful is still a puzzle. ( ) F T 你能告诉我他住在什么地方吗？Could you tell me where he lives? ( )Could you tell me where does he live? ( ) T F

7. 二、名词性从句连接词的选用 1.that 和what 的选用 that 和 what 都可引导所有的名词从句。但是，what除起连接作用外，还在名词性从句中充当成分，可做从句的主语、宾语、或表语。而that在名词性从句中不充当任何成分，只起连接作用。

8. that / what What 1.______ he wants is a book. 2. ______ he wants to go there is obvious.3.The result is ______ we won the game.4.This is _____ we want to know.5.Is _____ he told us true ?6.We should pay attention to ______ the teacher is saying.7. I have no doubt _____ he will come.8. I have no idea _____ he did that afternoon. 9._____ has made China_____ it is now. That that what what what that what what what

9. 2.whether与if的辨用 whether 与 if 均为 “是否” 的意思。但在下列情况下，whether 不能被 if 所取代： 1.whether 引导主语从句,表语从句,同位语从句, 不用if，如： Whether it is true remains a problem. The question is whether you should accept it. The question whether he’ll attend the meeting is important. 2.whether可以引导从句作介词的宾语，而if 则不能，如： I’m not interested in whether they’ll go or not. 3.whether可以直接跟动词不定式连用，而if 则不能， I didn’t know whether to laugh or to cry. 4.whether or not 连在一起引导宾语从句时不用if

10. Practice time if / whether Whether if / whether1. I asked her __________ she had a bike.2.______ we will hold a party in the open air tomorrow depends on the weather.3.

11. 3.其它连接代词和副词的连用 主要根据名词性从句中的具体意义,正确的选择who、which、when、where、why、how 等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。

12. 我们何时举行运动会还没有决定。________ we shall hold our sports meeting is not decided.我不知道昨天谁打破了玻璃。I don’t know _________ broke the glass yesterday.我不知道他长的什么样子。I have no idea _________ he looks like.这就是我忘记眼镜的地方。This is _________ I left my glasses. When who what where

13. 三。宾语从句的时态呼应 1. 如果主句时态是现在时或将来时,从句谓语 可根据句意需要而选用任一种时态.a .他相信他的梦想总有一天会实现的. He believes _________________________ . b .请告诉我你昨天这个时候在干什么.Please tell me _________________________. his dream will come true some day whatyou were doing at this time yesterday

14. 2. 如果主句谓语是过去时,从句谓语动词一般用过去的 某种时态,但从句表达的是客观事实、真理、自然规 律等时，从句谓语通常用一般现在时。 他告诉我他正在为考试做准备。He told me ______________________ .他说他已离开家乡十年了。He told me ______________________.老师告诉我们光是沿直线运行的。The teacher tell us ______________________ he was preparing for the examination He had been away from his hometown for ten years light travels in a straight line.

15. 同位语从句和定语从句的区别 1.定语从句是先行词的修饰语，它不涉及先行词的具体内容。定语从句中that不但起连接作用，而且在定语从句中充当一个句子成分，充当从句的宾语成分时可省略。 2.同位语从句对中心词的内容作进一步的解释和说明，表明中心词的具体内容。引导同位语从句的that在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略.

16. Identify the type of clause in the following sentences The news that our football team won excited us. The news that we got excited us. that our football team won excited us. Appositive Clause that we got Attributive Clause “that” 在同位语从句中不充当任何成分，只起连接作用,一般不可省略。 在定语从句中充当主语或宾语，做宾语时可以省略。

17. 几个固定句式： ① 强调句 It is/was +强调部分＋that…….(如果强调部分是疑问词) Who is it that spoke first? When was it that they came here? ② 关于doubt sb. doubt if/whether….. sb. don’t/doesn’t that ……. There is no doubt that ……. There is no doubt that he will win the game. ③ 疑问词＋do you think+(用陈述句语序) Who do you think we invited to give us the talk?

18. 名词性从句中主句和从句的主谓一致、语序 主语从句做主语相当于单数第三人称作主语，谓语动词用单数，如果由and 连接两个或两个以上的主语从句做主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用单数。如： When the meeting will begin has not been decided yet.  When they will start and where they go have not been decided yet.
