5.名词性从句的用法

其实名词性从句也不难，只要仔细研究，很容易掌握的。以下为详解，满意请采纳哈~
一、概说 名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。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，是主语从句，是表语从句，而同位语从句则很少考查。
二、名词性从句的一般引导词
1. 连接词 that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。如 I hope (that) you enjoy your holiday. 希望你假期过得好。 That he likes you is very obvious. 很显然他喜欢你。
2. 连接词 whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成 if，但引导其他名词性从句时不能换成 if。 He asked whether I would show him the way. 他问我是否可以给他带路。 Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。(引导主语从句，不能用 if 代替 whether)
3. 连接代词 who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。如 That’s why she wanted to leave. 这就是她想离开的原因。 When we arrive doesn't matter. 什么时候到没有关系。 Tell me which one you like best. 告诉我你最喜欢哪一个。
4. 连接副词 when, where, why, how 等，也各自有自己的意义，在从句中作状语。如 The question is how we should carry out the plan. 问题是怎样执行这个计划。 When she’ll be back depends much on the weather. 她什么时候回来在很大程度上要看天气。 Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。
三、名词性从句的重要引导词
1. what 用于引导名词性从句是一个十分重要的引导词，它可引导主语从句、宾语从句和表语从句，但不用于引导同位语从句。它引导的名词性从句有两个意思是一是表示“什么”，带有疑问意味；二是表示“…所…的”，相当于一个先行词后接一个关系代词。如 I don’t know what you want. 我不知道你想要什么。 I don’t know what you want is this. 我不知道你所想要的是这个。
2. what 引导名词性从句时可用作限定词，其后修饰名词。如 I gave him what books I had. 我把我所有的书都给他了。 He gave me what money he had about him. 他把身边带有的钱全给了我。 注what 后的名词可以是复数名词或不可数名词，但通常不能是单数可数名词，并且后接不可数名词时，有时可有little修饰，两者的区别是what 不可数名词=所有的都，what little 不可数名词=虽少但全部。如 What friends she has are out of the country. 她有的那些朋友全在国外。 We gave him what (little) help we could. 我们给了他我们力所能及的帮助。
3. whoever, whatever, whichever 等也可引导名词性从句，其意分别为“所…的一切事或东西”、“任何…的人”、““…的任可人或物”等。如 Whoever wants the book may have it. 任何人要这书都可拿去。 I’ll do whatever I can to help him. 我们将尽我们所能来挽救他。 Buy whichever is cheapest. 买最便宜的。 注意以下受汉语意思影响而弄错的句子 任何人来都欢迎。 误Who es will be wele. / Anyone es will be wele. 正Whoever es will be wele. / Anyone who es will be wele. ，它们也可引导让步状语从句，其意为“无论…”、“不管…”，其意相当于 no matter who 。如 Whatever happens, you must be calm. 不管发生什么情况，你都必须镇静。(whatever = no matter what) He won't eat you, whoever he is. 不管他是谁，他也不能把你吃掉。(whoever = no matter who) 注whoever 既用作主格也用作宾语；作宾语时不宜用 whomever，因为在现代英语中 whomever 这个已几乎废弃不用。
4. why 与 because 的用法区别。两者均可引导表语从句，但前者强调结果，后者强调的原因。如 I had a cold. That’s why I didn't e. 我感冒了，我没来。 I didn’t e. That’s because I had a cold. 我没有来，那是因为我感冒了。
五、名词性从句的语序 名词性从句的词序与陈述句语序相同，尤其注意那些由连接代词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用法的影响而误用疑问句词序。如 Why was she crying? 她为什么在哭？ I don’t know why he was crying. 我不知道她为什么哭。
六、名词性从句的时态问题
1. 当主句的谓语动词是过去式时，宾语从句若不是一个客观事实或真理，其谓语动词也必须用某种过去时态。如 She said that she didn't want to know. 她说她不想知道。 I asked her whether she would agree. 我问她是否会同意。
2. when, if 这两个词既可引导名词性从句，也可引导状语从句。当它们引导名词性从句且表示将来意义时，要直接使用将来时态；但当它们引导状语从句且表示将来意义时，则必须用一般现在时表示将来意义。如 I don’t know when he will e, but when he es, I’ll call you. 我不知道他什么时候，但当他来的时候，我会打电话给你。 句中第一个when 引导的是宾语从句，故用将来时态表示将来意义；第二个when 引导的是时间状语从句，故用一般现在时表示将来意义。

6.名词性从句用法

语法复习-表语从句 1． 定义用作表语的从句叫做表语从句。 2． 构成关联词 简单句 3． 引导表语从句的关联词的种类
(1) 从属连词that。如 The trouble is that I have lost his address. 麻烦是我把他的地址丢了。
(2) 从属连词whether, as, as if。如 He looked just as he had looked ten years before. 他看起来还与十年前一样。 The question is whether they will be able to help us. 问题是他们是否能帮我们。 注从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如 All this was over twenty years ago, but it’s as if it was only yesterday. 这都是20多年前的事了，但宛如昨天一样。 能跟表语从句的谓语动词一般为系动词be, seem, look等。如 It looked as if it was going to rain. 看起来天要下雨了。

9.英语语法-名词性从句

在复合句中，起名词作用的从句，称为名词性从句。根据句法功能，名词性从句可以分为主语从句，宾语从句?表语从句和同位语从句。名词性从句不论是用什么词来引导，从句都必须用陈述句语序，即“引导词 主语 谓语 其它”。疑问代词或疑问副词充当引导词时，有词汇意义且在从句中担当一定的成分;whether(if只用于宾语从句)作引导词仅有词汇意义且不在句中担当任何成分;如果从句的语法成分完整，主从句语意通顺时一般就该用that来引导。
一?that 用于引导宾语从句时通常可以省略，尤其是在口语中。而that引导主语从句?表语从句?同位语从句时一般不能省略。如:
He told me (that) the meeting had been put off.
That our volleyball team had beaten theirs pleased every one of us.
The problem with building the factory is that we are lack of money.
Word came that he has recovered from the bad disease.
that引导宾语从句时在以下几种情况中不能省略:
1. 宾语从句为多个并列句时，前面分句的that可以省略，但一个分句的引导词that不能省略。如:
He told me (that) he had entered a university in Nanjing and that he was enjoying the college life there.
2. 宾语从句本身为一个复合句且复合句中的从句位于主句前时，that不能省略。
He said that if I went there， he would go too.
She believes that what the teacher says must be right.
3. 主句与宾语从句加入了插入语时。
He said， in his opinion， that it was too early for middle school students to carry cell-phones.
4. that引导的宾语从句后置，用形式宾语it代替时。
China has made it clear to the world that it is strongly against terrorism.
5. 跟在介词but， besides， except等后引导宾语从句时。
Your position is very good except that there are a few mistakes.
二?that引导主语从句可以用形式主语it来代替并将从句后置，从而达到平衡句子的目的。这样的句式有:
1. It’s 名词 that…用于该句型的名词有a pity， a great pleasure， no wonder， (high) time等。
It’s a pity that you shouldn’t go with us to the concert tonight.
It’s high time that they started to work.
2. It’s 形容词 that…用于该句型的形容词有possible， necessary， important， natural， strange 等。
It’s true that his brother got his left hand hurt when he was working on the machine.
It’s necessary that we practiced speaking English as often as possible.
3. It 不及物动词 that… 用于该句型的不及物动词有happen， our， appear等。
It happened that a doctor was on the train at that very moment.
It ourred to me that I was going the wrong way.
4. It’s 过去分词 that…用于该句型的过去分词有said， reported， announced等。
It is said that two people got killed in the traffic aident yesterday.
It is announced that China is strongly against terrorism.
三?当that引导的宾语从句后接有补足语时，也习惯将从句后置，而用形式宾语it代替。即句型:主语 think/consider/find… it 补足语(形容词或名词) that宾语从句。如:
We all think it great fun that we learn English in Mr. Hu’s class.
Mr. Green considers it important that students should form good habits of learning.
四?doubt作动词时其后的宾语从句及作名词时其后的同位语从句只能用that来引导。如:
We don’t doubt that he is fit for this job.
There is no doubt that we Chinese are determined to s Taiwan from being separated from mainland.
五?名词the reason作主语或why开头的主语从句，其后的表语从句只能用that引导，不能用because。如:
The reason for ing late is that I was caught in the traffic jam.
Why she kept silent about the matter is that she didn’t want to be involved in it.
六?that和whether都不作句中成分，区别时要从主句来寻找信息。若主句中有question， hasn’t been decided， is not known yet， depends on， wonder， doubt…等词语时且表示“不肯定”或事物的“两面性”时应用whether;而表示“肯定性”?“单一性”则应用that。如:
例1 The question came up at the meeting ____ we had enough money for our research.
A. whether B. that C. what D. where
分析:本题主语the question后带有一个同位语从句，由于从句不缺少必要成分，C项不符合，D项放入从句也说不通顺，如果选B，则是肯定的陈述“我们有足够的钱搞研究”，这怎么会成为“问题”呢?而“是否有”才是我们在会上讨论的问题。故答案为A。

例2 Along with the letter was his promise ____ he would visit me this ing Christmas.
A. which B. that C. what D. whether
分析:本句为倒装句，主语promise后带有一个同位语从句。分析该从句可以发现句子必要成分完整，因而可以否定选项A?C，如果选D项，则表明两种可能“来”和“不来”，那和没“许诺”一样，不符合题意。而选B表示“肯定”，意思是“在信中他答应圣诞节时来看我们。”
