雅思阅读名词性从句的语法知识点
雅思阅读名词性从句是烤鸭们必须掌握的一个知识点，下面分享了相关的定义和备考方法，大家可以参考一下。
一、名词性从句的定义和分类在句中起名词作用的句子叫做名词性从句，该从句能作为主语、宾语、表语、同位语、介词宾语等成分。
所以，相应地，名词性从句有四个分类：主语从句、宾语从句、表语从句和同位语从句。
通常从句都需要有相应的连接词，名词性从句也不例外。
常见的名词性从句连接词可以分为三类：1. 不做任何成分的连接词：that、whether/if、as if/as though;2. 连接代词：what、whatever、who、whoever、whom、whomever、whose、whosever、which、whichever;3. 连接副词：when、whenever、where、wherever、how、however、why。
二、名词性从句的用法讲解1、主语从句：主语从句就是在复合句中充当主语成分的句子。
常见的主语从句的连接词有that、whether、who、when、how等。
主语从句的时态一般不受主句时态的影响和限制。
同学们还需要注意的是英语中为了避免头重脚轻，经常会把主语从句放在后面，用一个形式主语来代替。
给大家举个例子吧：It will never be known how and when this numeration ability developed, but it is certain that numeration was well developed by the time (that) humans had formed even permanent settlements. (剑 6 Test 2 passage 3)句子结构分析：主语是it，指代后面的由两个特殊疑问词how and when引导的主语从句，谓语是will never be known，but表转折，第二个it作形式主语，指代后面的that主语从句，系动词是is，表语是certain。

雅思语法名词性从句知识点汇总
说道雅思语法的名词性从句，首先想问大家一个问题，那就是，什么是从句：clause：s（subject）+v（verb）一个句子都要有一个独立的从句，简单句除外。
而名词从句是一个从属句，什么意思呢？就是名词性从句不能成为一个单独的完成的句子，它只能在句子中充当一个成分（part of a sentence）。
今天我们就讲怎么用名词从句。
1、连接词（conjunction）连接名词从句的连接词到底有哪些：that、which、who、whom、whose、what、if、whether、when、where、why、how、whoever、whomever、whenever、wherever、whatever、whichever。
这是所有的连接词，有些可要谨慎使用哦~这些连接词，有的也可以连接定语从句，但是同学们在雅思语法学习时要注意“that”这个连接词。
因为当that引导从句的时候，常常被省略。
还有一些连接词既可以做连接词，也可以做从句中的主语，比如“which”“who”“what”还有“who/which/what-ever”，注意“whom”做宾语成分。
2、When to use and How to use基本来说，名词从句通常有四种用法。
1）名词性从句做主语What she wore to the party really turned some heads.名词从句：“What she wore to the party”——连接词“what” 名词从句里的主语“she”，动词“wore”。
整个句子的动词“turned”，turned前面都是主语。
名词从句充当主语成分。
Whoever wants to know should ask me.我们来找这句话的动词，两个——“wants”和“should ask“。
“wants”的主语是“whoever”，“should ask”的主语是“whoever wants to know”。

宾语从句
在复合句中充当宾语
1. that引导宾语从句时无含义，不充当成分，常省略。 ★that不引导介词的宾语从句，至于except that, in that, save that, but that等是 复合从属连词。 I know (that) you have met him. Let's suppose that one day this happens to you. ★在及物动词和宾语从句之间常有间接宾语（指人）。例如： I told him (that) he was wrong. ★在少数动词如：think, believe, suppose, expect, imagine, calculate, fancy, reckon, be supposed , seem, appear, feel as if, look as if, look like等后面的从 句中的否定词经常转移到主句谓语动词上，这叫否定前置/否定转移 (hope“希望”, guess“认为”后的宾语从句否定不前置。I hope not.“我希望 不是那样的”，是I hope so.的否定式。I don't hope so.是对hope的否定：“我 不希望如此”。）如： I don't think it will be very cold today. I don't think you are right. I don't believe he has finished his work.

一
主语从句 在复合句中充当主语的从句
1.that引导主语从句 that引导主语从句时不同于其他的连词，既无词义也不作成分， 只起单纯的连接作用，且通常不可以省。为了强调that引导的主 语从句而置之于句首时，that不可省。 ①That the driver could not control his car was obvious. ②That she was chosen made us very happy. ③That he will come is certain. ④That he would take the risk is true. ⑤That he should have married her isn't surprising.
▲it做形式主语有以下几种不同的结构： (1)It + be + 形容词+ that-从句 ①It is likely that he will come. ②It is strange that she has ever trusted him. ③It is important that he (should) attend the meeting. ④It is best that he (should) go. 此句型在表示惊讶、喜悦、遗憾等感情色彩时，that从句中的谓语动词也 常用 (should) + v原形。 It is strange that no one should have objected to the plan. (2)It + be +名词+ that-从句 It is common knowledge that the whale is not a fish. It's a pity that he should have catched the train.
2. Another advantage of going to school at an early age is that children develop faster socially. 3. My view/idea/opinion/point is that young people should be encouraged to broaden their horizons.
4. 连接副词when, where, why, how引导的表语从句。 The problem seemed how we could make him understand it. The question is where we should go. 5. as if, as though引导的表语从句（常用虚拟语气）。 He looks as if he were angry. It looks as if it's going to rain.
(3) It + be + -ed分词 + that从句 It is said that he is a famous writer. It is reported that there will be a storm this afternoon.
▲在表示建议、要求、命令等意义的被动结构中，that从句中的谓语动词 常用(should) do。（参见虚拟语气部分） It is suggested that the meeting (should) be held this afternoon. It is demanded that he (should) leave at once. (4) It + seem/happen/appear等不及物动词 + that从句。（look不接that从 句，它接to be结构或形容词） It seems that he is wrong. It appears that they are in urgent need of help. He looks (to be) surprised/happy/sad.
从句讲解之一：名词性从句
Tracey
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。 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三类： 连接词：that、whether、if不充当从句的任何成分） 连接代词：what、whatever、who、whoever、whom、whose、which. 连接副词：when、where、how、why
翻译练习
【练1/2】 It is often important that you make it clear what your particular role is at a given time. (剑3，T2，R） 【练2/2】It is an unfortunate fact that many employers may prefer to use the services of children.（剑3，T3，W）
★通常，that引导主语从句时用it做形式主语，把从句置于句 尾，此时that有时可省。例如： ①It was obvious that the driver could not control his car. ②It made us very happy that she was chosen. ③It is certain that he will come. ④It is true that he would take the risk. ⑤It isn't surprising (that) he should have married her. ★如果以that从句为主语的句子是疑问句，就只能用先行词it 结构。例如： ①Is it certain that he will come? ②Is it true that he would take the risk?
2. whether引导主语从句，意为“是否”，只起连接作用，不充当任何成分。 （置于句首时必须用whether引导，置于句尾时，间或可用if。） Whether he will win the game is not clear. Whether he will come is uncertain. Whether she comes or not doesn't concern me. It is not clear whether/if he will come. It was uncertain whether he would come. 3. 连词代词what, who, which, whose等引导的主语从句。这些连接代词作用 相当于代词，在从句中担当主语、宾语、表语、定语等。 What we need is more time. Who was responsible for the accident is not yet clear. Which school you want to go matters much.
