名词性从句一．概述：在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用，这类从句又可分为主语从句、表语从句、宾语从句和同位语从句。
二．名词性从句连接词四．if, whether 的区别1.引导主语从句时，如果主语从句放在句首，只能用whether 不能用if 引导，但是如果用it 做形式主语，而把主语从句放在句末时，也可以用if 引导.2.引导宾语从句时常放在动词know, ask, care, wonder 之后，if 和whether 均可。
少数动词，如: leave, put, discuss, doubt 后的宾语从句常用whether.。
3.在介词后面的宾语从句中，在表语从句、同位语从句中，表“是否”，只能用whether；4.w hether 和if 都可以和or not 连用,但是whether 之后可以直接跟or not,而if 不可以。

专题三名词性从句名词性从句指在复合句中起名词作用的从句，它在句子中可作主语、宾语、表语或同位语。
名词性从句既是中学英语教课的要点，也是高考考察的热门。
一、名词性从句的分类名词性从句包含主语从句、宾语从句、表语从句和同位语从句。
其连结词有 that, if, whether；连结代词 who, what, which；连结副词 when, where, how, why 等。
考察热门一：对主语从句的考察主语从句在复合句中充任主语，它能够放在主句谓语动词以前。
但为了保持句子均衡，多半状况下可用it 作形式主语，而把主语从句置于句尾。
考察热门二：对宾语从句的考察宾语从句在句子中作及物动词或介词的宾语。
假如主句的谓语动词是及物动 make, find, see, think 等，则把宾语从句置于宾语补足语以后，用it 作形式宾语。
此外，某些作表语的形容词，如 sure, happy, glad, certain 等以后也能够带宾语从句。
考察热门三：对表语从句的考察表语从句在句子中作表语，位于主句中的系动词以后。
考察热门四：对同位语从句的考察同位语从句一般跟在某些抽象名词以后，进一步说明该名词所表示的详细内容。
可跟同位语从句的名词主要有：fact, idea, news, promise, belief, condition, doubt, fear, hope, problem, proof, question, reply, report, suggestion, thought, truth等。
二、对名词性从句的考察应注意以下几点：考察热门五：考察名词性从句的语序和主从句时态名词性从句均应用陈说句语序，其时态要保持主从句时态一致性。
考察热门六：从语境和句子构造需要出发，选择适合的连词（I）连词that 和what：that 无实质意义，在从句中不充任任何成分，只起连结主从句的作用；如 that 指引宾语从句，常可省略；如指引主语从句、表语从句或同位语从句， that 不可以省略。

名词性从句名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。
因此，名词性从句可分为主语从句、表语从句、宾语从句和同位从句。
（一）引导名词性从句的连接词1、连接代词：who, whose, whom, what, which。
有词义，在从句中担任成分，如主语、表语、宾语、或定语等。
2、连接副词：when, where, why, how。
有词义，在从句中担任成分，作状语。
3、连接词：that, whether, if, as if。
that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。
注意：连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。
连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。
根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。
（二）主语从句1、主语从句在复合句作主语。
e.g. Who will go is not important.2、用it作形式主语，主语从句放在句末。
e.g. It doesn’t matter so much whether you will come or not.3、that引导主语从句时，不能省略。
e.g. That he suddenly fell ill last week made us surprised.（三）表语从句1、表语从句在复合句中作表语，位于系动词之后。
e.g. The question was who could go there.2、引导表语从句的连接词that有时可省去。
e.g. My idea is (that) we can get more comrades to help in the work.（四）宾语从句1、宾语从句在复合句中作宾语。
引导宾语从句的连词that一般可省略。
e.g. I hope (that) everything is all right.2、介词之后的宾语从句，不可用which或if连接，要分别用what或whether。
e.g. I’m interested in whether you’ve finished the work..I’m interested in what you’ve said.3、whether与if都可以引导宾语从句，常可互换。
但下面情况不能互换。
①宾语从句是否定句时，只用if，不用whether。
e.g. I wonder if it doesn’t rain.②用if 会引起误解，就要用whether。
e.g. Please let me know whether you want to go.（此句如果把whether改成if，容易当成条件句理解）③宾语从句中的whether 与or not直接连用，就不能换成if；不直接连用，可换。
e.g. I don’t know whether or not the report is true.I don’t know whether/ if the report is true or not.④介词后的宾语从句要用whether引导。
whether 可与不定式连用。
whether也可引导主语从句、表语从句、同位语从句，还可引导让步状语从句，以上均不能换成if。
但引导条件从句时，只能用if，而不能用whether。
e.g. It depends on whether we have enough time.They don’t know whether to go there.Please come to see me if you have time.（五）同位语从句同位语从句在句中作某一名词的同位语，一般位于该名词（如：news, fact, idea, suggestion, promise等）之后，说明该名词的具体内容。
e.g. I have no idea when he will be back.The fact that he had not said anything surprised everybody.练习：名词性从句一、判断下列各句哪句含有名词性从句，并指出是什么从句：1. China is no longer what it used to be.2.
