名词性从句 : 主语从句, 表语从句, 宾语从句, 同位语从句
起名词性作用的从句，叫名词性从句。 换言之，在英语的句子结构中，本来该由名词充当的主语、宾语、 表语和同位语部分，换由一个句子来充当，这样的句子就是名词性 从句。
基本结构：简单句+并列连词+简单句。
并列连词通常为：and, but, or, so，not only…but also, neither…nor; as well as 等。
并列句：简单句+并列连词+简单句

高三名词性从句
名词性从句讲解在英语中，名词可以在句中充担主语、宾语、表语、同位语，个别时候还可以充担宾补，故而，我们把在句中充担主语、宾语、表语和同位语的句子统称为“名词性从句”。
根据它们在句子中的语法功用，我们把名词性从句分为四种，即：主语从句、宾语从句、表语从句和同位语从句。
Ⅰ）主语从句①经常用来引导主语从句的词有：从属连词：that（只起引导词的作用，在句中不充担任何成分，无意义。
），whether（在句中作状语，体现选择概念，意为“是否”。
whether … or … 意为“无论…… 还是……”，“不管…… 还是……”。
）连接代词：who(ever)（在句中用作主语和表语，意为“谁”，“无论何人”。
），whom(ever)（在句中用作宾语，意为“谁”，“无论何人”。
），whose （在句中用作定语，体现所属概念，意为“谁的”。
在省略状态下，也可以用作主语或表语等成分。
whosesoever意为“不管是谁的”，这一用法已经很少见。
），which(ever)（在句中用作主语、宾语、表语和定语，意为“哪一个”，“无论哪一个”。
），what(ever)（在句中作主语、宾语、表语或定语，意为“什么，多么”，“无论什么”。
what引导名词性从句时，不少时候并无确切的含义，要根据具体的语境来翻译，一般译作“所…… 的”，例如：所看到的，所听到的，所想到的，所说的，所做的等等。
）连接副词：when(ever)（在句中被用作状语，体现时间概念，意为“何时”，“无论何时”。
）where(ever)（在句中被用作状语，体现方位概念，意为“哪里”，“无论何处”。
），how(ever)（在句中被用作状语，体现程度或方式概念，意为“多少，多么，怎么样”，“无论多少，无论多么，无论怎么样”。
），why（在句中被用作状语，体现原因概念，意为“为什么”。
）That you’re coming to London is the best news I have heard this long time.It is natural that they (should) have different views.Whether it will do us harm or good remains to be seen.Whether this reading material can be used for listening has not been decided yet.It was uncertain whether he would come (or not).It matters little whether we will go or stay.It hasn’t been decided who will go to attend the meeting instead of Mr.Black.Whoever gets the job will have a lot of work to do.Whoever you are will be punished breaking the law.Whomever / Whoever you invite will be welcome.It is unknown who / whom he will invite to the party to-night.■在口语中，或者作介词宾语，介词又不置于其前时，经常使用who(ever)代替whom(ever)。

高三复习名词性从句和非谓语转换
名词性从句与非谓语一、名词性从句与动名词名词类的从句可以被化简成动名词和不定式。
1.2.1.that引导的主语从句与动名词例: 1(1) It surprised us that John won the marathon.John`s winning the marathon surprised us.例: 2(1)That he lost the game came as a surprised to everybody.That he knows English helps him start a conversation with foreigners例：3(1)That he was out of work was unexpected(2)That she was ill made her mother worried.(3)That he was chosen as our chairman made us excited.2.that引导的同位语从句与动名词由原来的同位语从句结构“名词+that同位语从句”变成了一个动名词结构“名词+of+动名词的复合结构”。
例: 1(1)There was no chance that Davy would come from the battle alive.(2)There was no chance of Davy coming from the battle alive.例:2(1)We were greatly encouraged by the news that china had launched another man-made satellite.(2)It is said that the book has been translated into many other languages.The book is said to have been translated into many other languages(3)It was reported that the bank in the local has been robbed in broad daylight yesterday(4)it is thought that he is the greatest person in the world.(5)It is arranged that the class meeting will be held next week.3.that引导的宾语从句与动名词由that引导的宾语从句的简化较为复杂，因为它可以转换成动名词，也可以转换成不定式，这主要与主句谓语动词的用法密切相关。

种类
功能

或定语
连接 引导从句，在从句中 副词 作状语

（5）含主语从句的复合句是疑问句时，主语从句不可提前。例如： Is it possible that it will rain in the evening?
It occurred to him that he failed in the examination√. That he failed in the examination occurred to him.×
（4）It doesn’t matter how/whether …结构中的主语从句不可提前。 例如：
(3) It ＋ 不及物动词 ＋ 从句 It doesn’t matter that… It happens/occurs that…
(4) It is＋ 过去分词 ＋ 从句 It is reported that… It is well-known that… It is said that…
事实是… …非常荣幸 …是常识
responsible for it rem√ain/remains a mystery to
us. and连接的两个名词性从句作主语,如果表示 两件事情,其谓语动词常用复数形式.
5. What you eat everyday√is/are bad for your
health.
6. What I have got is/a√re several ideas. ?
(2) 定语从句是形容词性的，其功能是修饰先行词，对先 行词加以限定，描述定的性质或特征；同位语从句是名词 性的，其功能是对名词进行补充说明。
1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一
一．主语从句
主语从句是在复合句中充当主语的从句，通常放在 主句谓语动词之前或由形式主语it代替，而本身放在句子 末尾。
1. It 作形式主语和it引导强调句的比较
It is a pity that you didn’t go to see the film. It doesn’t interest me whether you succeed or not. It is in the morning that the murder took place. It is John that broke the window.
6. 否定的转移 若主句谓语动词为think, consider, suppose, believe,
expect, fancy, guess, imagine等，其后的宾语从句若含有 否定意义，一般要把否定词转移到主句谓语上，从句谓语 用肯定式。例如：
I don’t think this dress fits you well. 我认为这件衣服不 适合你穿。
三．表语从句
表语从句在复合句中作表语的名词性从句，放在系动 词之后，一般结构是“主语＋连系动词＋表语从句”。可 以接表语从句的连系动词有be, look, remain, seem等。引 导 表 语 从 句 的 that 常 可 省 略 。 另 外 ， 常 用 的 还 有 the reason is that… 和It is because 等结构。例如： 1) The question is whether we can make good preparation in such a short time. 2) This is why we can’t get the support of the people. 3) But the fact remains that we are behind the other classes. 4) The reason why he was late for school was that he missed the early bus.
用it 作形式主语的句型
(1) It is ＋ 名词 ＋ 从句 It is a fact that … It is an honor that It is common knowledge that
(2) It is ＋ 形容词 ＋ 从句 It is natural that… It is strange that…
celebrate, dislike, love, help, take, forgive等。这类词后可以用不定 式或动名词作宾语，但不可以用that引导的宾语从句。如：
I admire their winning the match√.
I admire that they won the match×.
The reason is that he is ill. √
四．同位语从句
同位语从句就是在复合句中作名词的同位语的名词性从句。
1. 同位语从句的功能 同位语从句对于名词进一步解释，说明名词的具体内容，一般由
that引导，例如： 1) The king’s decision that the prisoner would be set free surprised all the people. 2) The order that all the soldiers should stay still is given by the general.
个that引导的从句是定语从句，that在从句中作宾语）
2)The news that Tom would go abroad is told by him.（汤 姆将出国的消息是他讲的。）（同位语从句，that在句中不作
任何成分）
应该注意的几个问题
1) that vs. what What we can't get seems better than what we have. That we should work out a plan to deal with the present serious situation is important. = It is important that…
2. 同位语在句子中的位置 同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的
词隔开。例如： He got the news from Mary that the sports meeting was put off.
3. 同位语从句与定语从句的区别： n. + that ?
(1) 定语从句中的that既代替先行词，同时也在从句中作 某个成分（主语或宾语），而同位语从句中的that是连词， 只起连接主句与从句的作用，不充当句中任何成分。
2. Why she did this√is/are not known.
以who, why, how, whether或that引导的从句作主语时,谓语 动词通常用单数形式.
3. How and why he had come to Princeton New Jerse√y is/are a
story of struggle, success and sadness.
Is that will rain in the evening possible? √
1. What I say and think is /a√re none of your business.
