名词性从句
在句子中起名词作用的句子叫名词从句 (Noun Clauses)。 名词从句的功能相当于名词词组, 它在复合句中能高考资源网担任主语、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。w.w.w.k.s.5.u.c.o.m
高考重点要求：
1、 掌握主语从句、宾语从句、同位语从句、表语从句的基本句型结构
2、 弄清名词性从句的连词的用法和意义
3、 根据句子语义确定使用何种从属连词
第一节 知识点概述
一、引导名词性从句的连接词
引导名词性从句的连接词可分为两类：
1. 名词性that从句，即以that为连接词的名词性从句。that只能起连接主句和从句的作用，不充当从句的任何成分，无词义。
2. 名词性wh-从句，即以wh-词连接的名词性从句。Wh-词包括：
连接代词：who, whom, whose, what, which, whoever, whatever, whichever
连接副词：when, where, how, why
连接词whether, if不充当句子的任何成分。
二、主语从句
1. 用作主语的从句叫主语从句。that从句作主语，that不能省略。
▲That he likes such kind of books is very interesting.他喜欢这种书是非常有趣的。
▲Whether he will be able to come remains a question. 他是否能够来仍然是一个问题。
▲What he is looking for is none of your business. 他在找什么与你无关。
2. 很多主语从句都可以用that作形式主语。例如：
It is very interesting that he likes such kind of books. w.w.w.k.s.5.u.c.o.m
It remains a question whether he will be able to come.
3. It作形式主语主要包括以下几种类型和搭配关系：
1）It + be + adj. + 从句
It was obvious that the driver could not control his car.
2）It + be + n. + 从句
It is a pity that he missed the lecture.
3）It + be + 过去分词 + 从句
It is said that they have won the game.
4）It + be + vi. + 从句w.w.w.k.s.5.u.c.o.m
It seems that something is wrong with the computer.
三、表语从句
表语从句在句中作表语，它位于主句的联系动词之后。that从句作表语，that不能省略。表语从句只用whether，不用if。
▲The problem is that smokers cannot go without smoking. 问题是抽烟的人不抽烟就会感到难受。
▲The question is whether it is worth doing. 问题是这是否值得做。
▲This is where he has worked for years. 这就是他多年工作的地方。
四、宾语从句
宾语从句在句中作宾语，引导宾语从句的that可以省略。whether和if可互换，但介词宾语或有or not时，用whether.
▲They know that the habit may kill them. 他们知道这个习惯能使他们致死。
▲They doubt whether or not Jack is a good student. 他们怀疑Jack是否是一个好学生。
▲They wanted to see which shops offered the best advice and service. 他们想了解哪家店提出的建议和提供的服务最好。
五、同位语从句
同位语从句中先行词不充当从句成分，从句是用来解释先行词的内容。That从句作同位语，that不能省略。
▲Word came that our football team had won the match. 消息传来，我们的足球队赢了比赛。
▲May I ask a question when the meeting will be held? 我能否问个问题，会议什么时候举行？w.w.w.k.s.5.u.c.o.m

第二节 实战演练
一、复习时需注意的要点
1. 由从属连词that引导的从句叫做名词性that-从句。 That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。名词性that-从句在句中能充当主语、宾语、表语、同位语
2. 主句和从句要保持时态上的一致性，从句还要保持陈述句语序。
3. 当从句是由选择问句转化而成时，一定要用whether构成whether...or结构。
4. That-从句作主语通常用it作先行词，而将that-从句置于句末，例如：
It is quite clear that the whole project is doomed to failure.很清楚，整个计划注定要失败。
It's a pity that you should have to leave.　你非走不可真是件憾事。

用it作形式主语的that-从句有以下四种不同的搭配关系：
a. It + be + adj. + that从句w.w.w.k.s.5.u.c.o.m
　It is necessary that…有必要……
　It is important that…重要的是……
　It is obvious that… 很明显……
b. It + be + 过去分词 + that从句
　It is believed that…　人们相信……
　It is known to all that…从所周知……
　It has been decided that… 已决定……
c. It + be + n. + that从句　It is common knowledge that………是常识
　It is a surprise that… 令人惊奇的是……
　It is a fact that… 事实是……
d. It + be + vi. + that从句
It appears that…似乎……
It happens that…碰巧……
It occurred to me that… 我突然想起……
5. 选择性疑问从句
选择性疑问从句由关联词whether…or或whether…or not构成，例如：
Please tell me whether they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。
I don't care whether you like the plan or not.我不在乎你是否喜欢该计划。
