名词性从句用法详解
来源：普特英语
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，其次是主语从句，再次是表语从句，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。如：
He asked whether [if] 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。

学习名词性从句的应注意的关键点
1. 备考主语从句应注意以下三点
一是从句作主语，主句谓语动词用第三人称单数；
二是主语从句通常用it作形式主语，尤其是在It is +名词/ 形容词/ 过去分词+that…中，或在It see ms / happens that…中，或疑问句中；
三要注意由what, whatever, whoever引导的主语从句一般不用形式主语。
2. 备考宾语从句应注意以下四点
一是介词后(except等除外)一般不跟that引导的宾语从句，但可接疑问词引导的宾语从句；二是在that引导的宾语从句后若还有补语时，要用it作形式宾语，而将that从句置于补语之后；
三是当主句谓语动词是think, believe, suppose, expect, imagine等时，若宾语从句要表示否定意义，往往要通过否主句来实现，即所谓否定转移；
四是虽然引导宾语从句的that有时可以省略，但若宾语从句前有插入语或有间接宾语时，that 不能省略；that在与之并列的另一个宾语从句之后或者在“形式宾语it+宾补”之后时也不能省略；that从句单独回答问题时，that也不能省略。
3. 备考表语从句应注意以下三点
一是除that, whether和疑问词外，as, as if, as though, because也可引导表语从句；
二要注意“that’s why+结果”以及“that’s because+原因”的区别；
三是注意the reason (why / for…) is that…句式。
4. 备考同位语从句应注意以下三点
一是同位语从句多在news, order, word (=news / order), idea, hope, suggestion, information, plan, thought, doubt, fear, belief等抽象名词后，说明其具体内容；
二是同位语从句与所说明的名词有时会被谓语所分开，做题时需注意；
三是引导同位语从句的有that, whether和连接副词when, where, why, how等，但绝大多数由that引导，注意同位语从句不能用which引导。
that与what引导名词性从句的区别
that引导名词性从句只起连接作用，在从句中不作任何成分，无意义，在宾语从句通常省略，但在主语从句、表语从句和同位语从句中均不能省略；what除引导从句外，还在从句中作成分，意为“所……的(东西)”，在含义上等于“名词+that”。如：
1. 用that的例子
That she lacks experience is obvious. 她缺少经验，这是显然的。
The police learned that he wasn’t there at that time. 警察获知他那时不在场。He realized that she too was exhausted. 他意识到她也精疲力尽。
My idea is that you shouldn’t have left the country. 我的意见是你不应该离开那个国家。
Bob has the mistaken idea that tomorrow is a holiday. 鲍勃错误地认为明天是一个假日。
It was quite plain that he didn’t want to come. 很明显他不想来。
It is natural that they should have different views. 他们看法不同是很自然的。
2. 用what的例子
What (=The thing that) he said was true. 他所讲的是事实。
What he had hoped at last came true. 他希望的事终于成为现实。
What he said is beneath contempt. 他说的话不值一理。
What he says is true, possibly. 或许他说的是对的。
What she saw gave her a fright. 她看到的情况吓了她一跳。
What I want to say is this. 我想说的是这一点。
I’m sorry for what I said. 我为我说的话表示歉意。
That’s what I want to know. 这是我想知道的。
You had better hear what I have to say. 你最好听听我的意见。
I managed to get what I wanted. 我设法得到了我要的东西。
It was what he meant rather than what he said. 这是他的原意而不是他的原话。There’s something in what he says. 他的话有些道理。
Her interest was roused by what he said. 他的话引起了她的兴趣。
He was always conscious of the fact that she did not approve of what he was doing. 他一向清楚她不太赞成他的做法。
注：that 可引导同位语从句，what不能。如:
Have you any idea what time it starts? 你知道什么时候开始吗? whatever, whoever, whichever引导名词性从句
1. whatever引导的名词性从句
Whatever的意思是“所…的一切事或东西”，可视为what的强调说法，其含义大致相当于anything that，whatever在从句中可用作主语、宾语、定语：
Whatever he did was right. 无论他做什么都是对的。
Give them whatever they desire. 他们想要什么就给他们什么。
I will just say whatever comes into my mind. 我想到什么就说什么。

2. whoever引导的名词性从句
whoever的意思“任何…的人”，在意义上大致相当于 anybody who。whoever在从句中可用作主语或宾语：
I’ll take whoever wants to go. 谁想去我就带谁去。
She can marry whoever she chooses. 她愿意嫁谁就嫁谁。
Whoever wants the book may have it. 任何人要这书都可拿去。

I’ll give the ticket to whoever wants it. 请想要这票，我就把它给谁。
【注意】
(1)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已几乎不用)。
(2) 注意以下受汉语意思影响而弄错的句子：
误：Who wins can get a prize. / Anyone wins can get a prize.
正：Whoever wins can get a prize. / Anyone who wins can a prize. 谁赢了都可以获奖。
whatever与no matter what
有这样一道题：
It is generally considered unwise to give a child __________ her or she wants.
A. whatever
B. no matter what
C. whenever
D. no matter when
此题应选 A。容易误选B。选项C、D显然是错的，因为句中的 wants 缺宾语，而C、D两项不能作宾语。至于C、D 的区别，可这样描述：no matter what 只能引导状语从句，而不引导名词性从句。而 whatever 既可引导名词性从句(＝anything that)，也可引导状语从句(＝no matter what)：
1. 引导名词性从句(只用whatever)：
无论他做什么都是对的。
正：Whatever he did was right.
误：No matter what he did was right.
无论他说什么似乎都有道理。
正：Whatever he says sounds reasonable.
误：No matter what he says sounds reasonable.
山羊找到什么就吃什么。
正：Goats eat whatever they find.
误：Goats eat no matter what they find.
2. 引导状语从句(两者可换用)：
无论你说什么，我都不会相信你。
正：Whatever you say，I won’t believe you.
正：No matter what you say，I won’t believe you.
无论发生什么，都要保持镇定。
正：Keep calm，whatever happens.
正：Keep calm，no matter what happens.
whether 和if引导名词性从句的区别
两者均可用于及物动词后引导宾语从句，表示“是否”，常可互换。但除此(用于动词后引导宾语从句)之外，在其他情况下表示“是否”时，通常要用 whether 而不用 if，如用于引导主语从句、表语从句、同位语从句、让步状语从句、与or连用分别引导两个分句等，或用于不定式前、用于介词后、直接与 or not 连用等等。如：
Ask him whether [if] he can come. 问他能不能来。
The question is whether he can do it. 问题是他能不能做。
Answer my question whether you can help him. 回答我你是否能帮助他。
It depends on whether the letter arrives in time. 这取决于信是否来得及时。注：在某些动词后(如 discuss 等) 通常只用 whether。如：
We discussed whether we should hold a meeting. 我们讨论了是否要开一个会。

高一语法专题：名词性从句 在句子中起名词作用的从句叫名词性从句。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，因此根据它在句中不同的语法功能，名词性 从句又可分为主语从句、宾语从句、表语从句、同位语从句。 引导名词性从句的词叫做连接词，包括：1. 连词（在名词性从句中只起连接作用，不 作成分） 2. 连接代词（在名词性从句中作主语、宾语 或表语） 3. 连接副词（在名词性从句中作状语） I 主语从句：是在主句中作主语的从句。它由连接词引导，通常位于谓语动词之前。 连接词：
1. 连词：在从句中不充当任何成分，常见的引导主语从句的连词有that, whether。 That he got the first prize excited him much. 他获得一等奖一事使他非常兴奋。 It is doubtful whether we can get there on time. 我们能否按时到达那儿还不确定。 1）that引导的主语从句：在从句中不作任何成分，也没有实际意义。一般情况 下that不可省略。 That light travels in straight lines is known to all. 众所周知，光沿直线传播。 That you don't like him is none of my business. 你不喜欢他不关我的事。 2）whether引导的主语从句：常置于句首，表示“是否”之意；
Whether he can finish his task on time is of great importance. 他是否能按时完成任务非常重要。 Whether you can succeed or not depends on how hard you work at it. 你能否成功取决于你努力的程度。 2.连接代词：在从句中起名词或代词的作用，常作从句的主语、宾语、表语或定语，有具 体意义且不能省略。常见的连接代词有who, whom, whose, what, which, whoever, whomever, whatever, whichever。 What we should do with the problem is undecided. 我们如何处理这个问题还未作出决定。（what引导主语从句，不表疑问意义） Whom the letter was from is still unknown.
一、在名词从句中连接词which 有两种词性, 常用来引导宾语从句： 1. [连接代词] 哪个 1）用作从句的主语，如： He wanted to know which was on the table. 他想知道哪一个在桌子上。 2) 用作从句的宾语，如： He asked me which I liked best. 他问我最喜欢哪一个。 2. [连接形容词]放在名词前作定语，表示“哪个XX，哪些XX”，如： Do you wnow Which country is the largest? 你知道哪国家一个最大? Could tell me which children made him still more angry. 能告诉我那些 孩子使他更加生气了。 二、which 除引导上述宾语从句外，还可以引导主语从句和表语从句。 1. 主语从句(常用形式主语it) It was clear which children made him still more angry. 显而易见那些孩子使他更加生气了。 It is known to us which he liked best. 众所周知他最喜欢哪一个。 2. 表语从句 That was which children made him still more angry. 那就是那些孩子使他更加生气了。 This is which he liked best. 这就是他最喜欢哪一个。 三、which 与what 的区别 用在名词从句中，which 意思是“哪一个/那一些”，what 意思是“所...的”，后者等于“先行词+关系代词”，如你的补充问题就需要选择what： It's quite different from what I read last month. = It's quite different from (the one that) I read last month. 这本书与我上周所读过的那一本区别很大。 1.that在所有名词性从句中无成分无意义。 2.which强调哪一个，有一个选择的范围。 从句中from后边缺宾语，所以要选择的是宾语从句的引导词，首先that引导宾语从句时，不做介词宾语（除了in,except,but) 其次read后边缺宾语，也就是从句中缺成分，参见上面第一条，所以排除that.B选项which指哪一个，这里
名词性从句归纳 一、名词性从句概说、结构与功能 名词性从句是起名词作用的从句，其功能相当于名词词组，在复合句中可作主语、宾语、表语和同位语。与之对应的名词性从句分别为主语从句、宾语从句、表语从句和同位语从句。 二、主语从句 1、主语从句的类别 ●以从属连词that 引导的主语从句。（从句位于句首，that通常不省略） → That she will come to the conference has excited every one of us. ●以从属连词whether 引导的主语从句。（从句置于句首时一般不用if来代替whether） → Whether we’ll go outing depends on the weath er. ●以连接代词（what, whatever, who, whoever, which, whichever等词）引导的主语从句。 → Whoever will be in charge of the project hasn’t been decided yet. 【注】what 与that在引导主语从句时，what 不但起连接作用，而且还有具体意义，意为“所…的”，相当于the things that结构；而that则无词义。即如果从句中不缺少主语或宾语时，选择that，否则用what。 ●以连接副词（when，where, how, why 等词）引导的主语从句. → When the new road is open to traffic has not been made clear. 2、用it 作形式主语的主语从句 注：以下几种特殊情况必须用it作形式主语： ⑴ It is + adj. + that 从句 常见的形容词有：necessary，right，likely，wrong，important，certain，clear，obvious，strange 等。 → It is likely that there will be a snowstorm tomorrow. ⑵ It is + noun + that 从句 常接这种句型的名词有：a pity, a shame, good news, a fact, an honor, a wonder, no wonder 等。 → It is a pity that you didn’t attend the lecture [讲座] yesterday. ⑶It is + 过去分词

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，名词性从句厅分为主语从句、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： 1、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）。 2、不可省略的连词： （1）介词后的连词 （2）引导主语从句和同位语从句的连词不可省略。 That she was chosen made us very happy. We heard the news that our team had won. （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. 主要句型有： （1）It+be+形容词+that从句。 It is probable that he told her everything. 很可能他把一切都告诉她了。 （2）It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。 （3）It+be+过去分词+that从句。 It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。 （4）It+seem, happen等不及物动词及短语+that从句。 It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。 （5）It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。 It doesn’t matter whether she will come or not. 她是否来这无关紧要。 It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。 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. 4、当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。 What we need is more time and money. What we need are many more books. 5、if不能用在主语从句中，而是用whether Whether he left (or not) is unknown 6、引导主语从句的关联词有三类： (1)从属连词that。

英语语法名词性从句用法小结 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、同位语等，因此根据它在句中不同的语法功能，名词性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。 一. 名词性从句的连接词 引导名词性从句的连接词可分为四类： 1. that（无含义，不充当成分） 2. whether, if（有“是否”的含义，但不充当成分） 3. 连接代词：what, whatever, who, whoever, whom, whomever,whose, which,whichever. （在从句中做主语、宾语、表语和定语） 连接副词：when, whenever,where,wherever, how, however,why（在从句中做状语） 4. as if,as though,because（不充当成分，在名词性从句中只引导表语从句） 二. 四类名词性从句语法要点 1.主语从句 在整个句子中用作主语的从句叫主语从句。 What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。 Where the English evening will be held has not yet been announced.
英语晚会将在哪里举行，还没有宣布。 it 作形式主语：有时为避免句子头重脚轻，常用形式主语it 代替主语从句作形式主语放 于句首，而把主语从句置于句末。 It is clear that he is innocent in the accident. 很明显，他在这场事故中是无辜的。 2. 宾语从句 在整个句子中用作宾语的从句叫宾语从句。 He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。 We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。 it 作形式宾语：在“主语+谓语+宾语+宾补”的句型中，如果宾语是从句的形式，则必须 用it 做形式宾语，把真正的宾语即宾语从句置于句末。 We found it impossible that the so much work will be finidhed in one day. 我们发现一天之内完成这项工作不可能。 3. 表语从句 在整个句子中用作表语的从句叫表语从句。 The fact is that we have lost the game. 事实是我们已经输了这场比赛。 That is why he didn’t come t o the meeting.
that引导名词性从句用法详解 如何来掌握that引导的名词性从句呢？我认为应从以下几个方面掌握： 一．that 在名词性从句中，起连词的作用，在从句中不起语法功能，即不作任何成分，也不含有任何意义，引导名词性从句时，不可省略，故称：“三不”。 二．that引导名词性从句的特点 引导同位语从句： 当that引导同位语从句时，that从句前常有名词， 1) The idea that england stands for fish & chips ,speaker’corner, big ben and the tower of london is past 2) The fact that great britain is made up of three countries is still unknown to many. 3) The suggestion that students should learn something practical is worth considering 与 that 同位的名词常有下列名词： news ，fact, hope, idea, suggestion, promise, thought, doubt, belief, truth, request, proposal, demand etc. 2. that 引导表语从句 当that引导表语从句时，常用下列句式： it happens that…. it appears that…. it seems that…. it turns out that…. it proves that…. the reason is that… 1) It appears that he has gone mad。他好像是疯了。 2) It proves that his promise is wrong.。他的预言证明是错误的。 3) The reason is that he has not passed the exam. 原因是他考试没有及格。 4) It turns out that the situation is quite serious.形势结果是相当严重的。 3. that 引导主语从句 由连词引导的主语从句，在大多数情况下被放到句子的后面，用it 作形式主语来代替它的位置。常见的以it作形式主语的主语从句的句型有三种。 + be + 形容词+that从句 适用于这种句型的常见形容词有：necessary，clear，true，strange，important，wonderful，possible，likely，abvious，surprising etc。 1) It’s clear that they badly need help。很明显，他们急需援助。 2) It is likely that a hurricane will arrive soon. 很可能飓风马上就要来了。 3) It’s possible that we can carry out the project at last. 最终我们能完成这项工程是有可能的。 *** necessary，clear，true，strange,important,wonderful，possible, likely, obvious, surprising, ashtonishing,etc.谓语动词的形式一般为“should ＋动词原形” 4) It is necessary that you (should)master the computer. 你很有必要掌握电脑。 5) It is important that a student learn english well. 学生学好英语很重要。 6) It is strange that he should have killed himself .真奇怪，他竟然自杀了 b. it +be +名词词组+ that从句

名词性从句基本用法及考点归纳 孝昌一中郭小青对名词性从句的考查是湖北卷完成句子试题很重要的一个部分，查看近几年的湖北高考完成句子都将名词性从句作为各种从句的必考点。如： 2007年湖北省高考题1:I haven’t the slightest idea(他正在说什么).(talk) 此题考查宾语从句、现在进行时和动词短语，答案是（of）what he’s talking about 2007年湖北省高考题2：The fact __（他失败了数次）makes him very upset (he, fail)此题考查同位语从句和现在完成时，答案是that he has failed (for) several times 2007年湖北省高考题3：(他是否出过国)doesn’t make much difference.(he, abroad) 此题考查主语从句和现在完成时，答案是Whether he has been abroad or not 2008年湖北省高考With the rapid development of science and technology，I can’t imagine_____________ (我的家乡会是什么样子) in ten years. ( what) 此题考宾语从句，答案是what my hometown will be/look like 注意用将来时且是陈述语序2010年湖北高考The news______________ (房价将要下跌) has caused many people to sell their houses at lower prices. 此题考同位语从句，用“that” 引导，“房价”译成“housing price”，答案是“that the housing price will fall”。 从中可看出，虽然对名词性从句的考查比重在下降，2007年有3道题涉及名词性从句的考查，而2008年，2009年只有一题，，但2010年还是再次考查了名词行从句中的同位语从句。可见，高中对名词性从句的把握还是很重要的。其命题规律：一般不给出连接词，增加题目难度；有时还会在期中穿插其他语法，比如说时态，语态，动词搭配等来增加试题难度。 当然，不管怎么考查，作为学生们首先得弄清楚名词性从句的其本用法。 名词性从句基本用法： 概念:在复合句中起名词作用的从句叫名词性从句(Noun Clauses)。名词性从句的功能相当于名词或名词词组, 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，名词性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。 名词性从句在功能上相当于名词： 如：主语：His job is important. What he does is important. 表语：This is his job.This is what he does every day. 宾语：I don’t like his job. I don’t like what he does every day 同位语：I don’t know about the man, Mr. White. I don’t know about the fact that he is a teacher. 一．主语从句：充当句子主语的从句 eg. That he will succeed is certain.
What 和that 在名词性从句中的用法区别 What 和that 都可以引导名词性从句。 一．在引导名词性从句时，从属连词that一般要注意三个不（three nos）： 1．不省略（no ellipsis） 当从属连词that引导主语从句、表语从句和同位语从句时，that不省略。 Eg. 1) That he was able to come made us happy.(That 引导主语从句不可省略) 2)The truth is that I didn’t go there. (that引导表语从句不可省略) 3)The news that our team has won is true. (that引导同位语从句不可省略) 但在非正式文体中that 引导宾语从句时可以省略，除下列两种情况外： that在宾语从句中不能省略的情况. (1). 在主+谓+it(形式宾语)+宾补+that，从句(真正宾语) 的句型中不省略. Eg: 4) He made it quite clear that he preferred to study English.（that不可以省略） 他很明确地说他宁愿学习英语。 (2). 由连词and连接的两个由that引导的宾语从句中, 则第二个宾语从句前的that不省略。Eg: 5) He told me that he would come and that he would come on time.（第一个That可以省略，但第二个that不可以省略。)他告诉我他将来而且他将准时来。 2．不作成分（no component） that 在名词性从句中不作任何句子成分。 Eg. 6)Sydney kept his promise that he would always do anything he could for Lucie to make sure of her happiness.（that在句中引导同位语从句，但在句中不作任何成分） 7))That you don’t like him is none of my business. (that在句中引导主语从句，但在句中不作任 何成分，也不省略） 3．没词义（no meaning） that 在名词性从句中没有汉语意思。 Eg. 8)That she is a rich woman is known to us. (that在句中引导主语从句，但在句中没有汉语意义) 她是一个很有钱的女子，这一点我们都知道。 9）The thought that he might fail in the exam worried him. (that在句中引导同位语从句，但在句中没有汉语意义） 他也许会考试失败，这一想法使他很担心。 二．在引导名词性从句时，What一般要注意一个不（one no）,一个有（meaning）,一个作（component）： 1．不省略 what 引导名词性从句时，what 在句中不省略。这一用法与that 用法不尽相同。 eg. 10) What I had for breakfast today was rice with egg.(what 在句中引导主语从句，what 不省略) 11)----I think it’s going to be a big problem. ----Yes , it could be . ----I wonder what we can do about. (what在句中引导宾语从句，但在句中不省略） 2．有词义 what 引导名词性从句时，有词义。一般是“----的东西/事情/话等”这一用法与that 用法不一样eg. 1) This is what she wanted to show us. (what在句中引导表语从句，在句中有词义，意思是“----的东西、事情）这是她想让我们看的东西。 12）What the teacher said had a good effect on the children. (what在句中引导主语从句，在句中有词义，意思是“----的东西、事情）老师所说的话对孩子们有很好的作用。 3．作成分
