高中英语 牛津必修三Unit2 语法梳理-名词性从句(二)
名词性从句（二）考情分析从高考的考查的实际情况来看，名词性从句考得最多的是宾语从句，其次是主语从句，再次是表语从句，而同位语从句考查得较少。
who,whom,whose,what，which,where,why,when,how可以引导主语、宾语和表语从句。
它们的特点：1.有本身的词义；2.在从句中担当句子成分，如：主语宾语或状语；3.引导的从句一律用陈述句语序，不能用疑回句语序。
I don't know who did it.我不知道这是谁干的。
She asked me where I had been.她问之前我在哪儿。
What you have done might do harm to other people.你所做过的事情有可能伤害别人。
Where he went for his weekend is not known.不知道他去哪里过的周末。
What I want to know is where he has gone for his weekend.我想知道的是他到哪里过周末去了。
规律总结名词性从句的语序与陈述句语序相同，尤其注意那些由连接代who(m）,whose,which,what和连接副词when，where,why等引导的名词性从句，不要受它们在特殊疑问句中的用法的影响而误用疑问句语序。
Why was she crying?她为什么在哭？I don't know why she was crying.我不知道她为什么在哭。
方法技巧what后的名词可以是复教可数名词或不可教名词，通常不是单数可数名词，并且后接名词时，有时可用litle/few修饰，两者的区别是：what+名词=所有的都，what little/few+名词=虽少但全部。
如：What friends she has are out of the country.她的朋友全在国外。
We gave him what little help we could.我们给了他我们力所能及的帮助。

高中英语语法解析---名词性从句
高中英语语法解析---名词性从句在句子中起名词作用的句子叫名词性从句(Noun Clauses）。
名词性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。

1. It 作形式主语和it引导强调句的比较It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。
而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。
被强调部分指人时也可用who/whom。
例如：{a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。
b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。
c) It is in the morning that the murder took place.谋杀案是在早上发生的。
（强调句型）d) It is John that broke the window.是John打碎的窗户。
（强调句型）2. 用it 作形式主语的结构(1) It is ＋名词＋从句It is a fact that …事实是…It is an honor that …非常荣幸$It is common knowledge that …是常识(2) It is ＋形容词＋从句It is natural that…很自然…It is strange that…奇怪的是…(3) It is ＋不及物动词＋从句It seems that…似乎…It happened that…碰巧…It appears that…似乎…"(4) It ＋过去分词＋从句It is reported that…据报道…It has been proved that…已证实…It is said that…据说…3. 主语从句不可位于句首的五种情况：（1）if 引导的主语从句不可居于复合句句首。

本文将对名词性从句、形容词性从句和副词性从句这三种常见的从句进行句子结构剖析，以帮助读者更好地理解和运用这些从句。
1. 名词性从句名词性从句在句子中担任名词的成分，通常用来作主语、宾语、表语或同位语。

名词性从句的句子结构较为简单，通常是一个完整的句子，与主句之间存在一定的从属关系。
下面是一些例子：- 主语从句：That he is late surprises me.（他迟到了让我吃惊。
）- 宾语从句：I know who did it.（我知道是谁干的。
）- 表语从句：My wish is that he may succeed.（我希望他能成功。

）2. 形容词性从句形容词性从句用来修饰名词或代词，并且起到形容词的作用。

形容词性从句常位于被修饰词后面，起到限定或描述的作用。
下面是一些例子：- The book that is on the table is mine.（在桌子上的那本书是我的。
）- The person who borrowed my phone is my friend.（借了我的手机的人是我的朋友。
）- I like the movie which is based on a true story.（我喜欢那部根据真实故事改编的电影。
