pep初中语法 名词性从句中that和what的用法区别
第3题补充3. 名词性从句中that和what的用法区别(转载)(2007-12-13 18:20:19)名词性从句中that和what的用法区别一．that 引导的名词性从句首先，连接代词that除引导第一个宾语从句时可以省略外，引导其他各类名词性从句皆不能省略。
例如：①It is required in the regulations that you should not tell other people the password of youre-mail account.②---- Don’t you think it necessary that he go home at once?---- but the problem is that there is no car.③There is much chance that Bill will recover from his injury in time for the race.④Our English teacher told us (that) we all did very well in the examination and that ten of us gotfull mark.以上四个句子中，that 分别引导主语从句，表语从句，同位语从句和宾语从句，除在第四个例句中第一个that 可以省略外，其他的that 均不可省略。
其次，在引导名词性从句时，that不作句子中的任何成分。
例如：①Nobody believed his reason for being absent from the class that he had to meet his uncle at theairport.该句中，that引导同位语从句，但在句中不作任何成分。
②It is our belief that improvements in health care will lead to a stronger, more prosperous economy.该句中，it 是形式主语，that引导的主语从句才是整个句子的真正主语，that在句中不作任何成分。
it和that和what
“that”在英文中是一个使用频率很高的单词。
它有四种词性，并且句法及语法功能纷繁复杂。
同学们如果不能熟练掌握其用法，很可能会形成英语学习的一种障碍，从而影响其学习兴趣和效率。
现将that的用法总结归纳如下：第一、that 用作形容词（后接复数名词时用those）。
它用来指已被提到的人或物；也可表对比，指两个中较远的那个。
What about that book you borrowed from me last month？请注意，that 有时候在句子中具有喜欢或轻蔑等感情色彩。
that little son of his 他那个小宝贝儿子That George！乔治那家伙！（含有轻蔑语气）第二、that 用作代词。
1. that 用作指示代词（复数形式是those），其指代意义同形容词用法，同时它还可以用作定语从句中的先行词；还可为了避免重复，代替前述名词。
That is what he told me.What is that (which) you have got in your hand?The price of rice is higher than that of flour.2. that 用作关系代词，引导限制性定语从句。
先行词可人可物，用法相当于who或which。
（但是在下列情况下多用that：先行词既有人又有物时；先行词有形容词最高级、序数词、不定代词、very，only等修饰时；先行词是不定代词时）He talked about the teachers and schools that he had visited.I think it one of the most wonderful films that the film company has ever produced.She has little information that is useful for our research.Is there anything that I can do for you?请注意，that 在定语从句中作宾语时通常可省略。
名词性从句中常用连接词的区别
名词性从句中常用连接词的区别作者：陈焕锁来源：《新高考·高一英语》2012年第03期名词性从句的功能相当于名词词组。
在句中作主语、宾语、表语和同位语。
因此，主语从句、宾语从句、表语从句和同位语从句通称为名词性从句。
名词性从句的连接词通常分为三类：第一类连接词在名词性从句中，不充当任何成分，只起连接作用。
这类连接词有：that, if, whether, as if, as though等。
例如：When a pencil is partly in a glass of water, it looks as if it were broken. 当铅笔一部分放进水里时，看起来好像断了似的。
第二类连接词在名词性从句中，作主语、宾语、表语、宾语补足语、定语。
这类连接词有：what, whatever, who, whoever, whom, whomever, which, whichever, whose等。
这类连接词称之为连接代词。
例如：Here are the chairs. Tell me which are worth buying. 就是这些椅子。
告诉我买哪几把好。
第三类连接词在名词性从句中，作状语。
这类连接词有：when, whenever, where, wherever, how, however, why等。
这类连接词称之为连接副词。
例如：The students asked the teacher when the examination was going to be held. 学生们问老师什么时候举行考试。
【名词性从句中常用连接词的区别】一、 what与that 的区别1. what引导名词性从句时，在从句中通常作主语或宾语，有时作表语或宾语补足语。
表示“……的东西、……的事情、……的话、……的时间、……的地方、……的人、所谓的……、……样子等”。
而that引导名词性从句时，在从句中不充当任何成分，也没有任何含义，只起连接作用。
高二英语名词性从句连接词what和that的用法辨析单选题20题
高二英语名词性从句连接词what和that的用法辨析单选题20题1. ______ he said at the meeting surprised all of us.A. WhatB. ThatC. WhetherD. If答案：A。
本题考查主语从句的连接词。
“What he said at the meeting”在句中作主语，what 在从句中充当宾语，表示“他在会上说的话”。
that 在主语从句中不充当成分，只起引导作用，此处需要一个充当成分的连接词，所以B 选项错误。
whether 和if 表示“是否”，在句中意思不通，所以C、D 选项错误。
2. ______ makes mistakes must correct them.A. WhoB. AnyoneC. WhoeverD. No matter who答案：C。
“Whoever makes mistakes”在句中作主语，whoever 表示“无论谁，任何人”，在从句中充当主语。
A 选项who 表示“谁”，语气没有whoever 强烈。
B 选项anyone 不能引导主语从句。
D 选项no matter who 只能引导让步状语从句，不能引导主语从句，所以选择C 选项。
3. ______ we need is more time.A. WhatB. ThatC. WhichD. Whether答案：A。
“What we need”在句中作主语，what 在从句中充当宾语，表示“我们需要的东西”。
that 在主语从句中不充当成分，只起引导作用，此处需要一个充当成分的连接词，所以B 选项错误。
which 表示“哪一个”，有选择范围，此处没有选择范围，所以C 选项错误。
whether 表示“是否”，在句中意思不通，所以D 选项错误。
4. ______ she will come or not is still a question.A. WhatB. WhetherC. IfD. That答案：B。
名词性从句知识点
复合句中具有名词性质并且可以做主语、表语、同位语或宾语的从句叫名词性从句。
因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。

2、引导名词性从句的词叫引导词。
引导词可以分为以下几类：1）从属连词that（用于表示肯定的含义）, whether, if (表示疑问)，这三个词只起连接作用，不充当从句中的任何成分，除宾语从句外（that可省）,这些词均不可省略。
2）连接代词有who, whom, whose, what, which, whoever, whatever, whichever等。
这些词在从句中既起连接作用，又充当从句中的成分，如主语、宾语、表语、补语，且不可省略。
3）连接副词有when, where, why, how, wherever, however等。
它们既起连词作用，本身又做从句中的状语。
3、名词性从句中的时态一致问题1）在宾语从句中，当主句是一般现在时、将来时或现在完成时，起从句的谓语根据需要用适当的时态。
当主句是一般过去时，从句用过去的某个时态，但若宾语从句表示客观真理，格言，谚语等，从句的时态仍用一般现在时。
Have you told him that when we are to leave?Teacher told us that China lies in the west of Japan.Although she was listening, she didn’t hear what he was saying because t here was so much noise.2）在主语从句、表语从句或同位语从句中，应注意主语从句中的谓语动词的时态一致性及动作发生的先后关系。
名词性从句中that和what的用法
名词性从句中that和what的用法作者：晏飞来源：《求学·新高考版》2021年第07期在高考英语中，名词性从句中that和what的用法是学生容易混淆的一个问题。
高考英语语法填空题中，连接词的用法是必考的内容，其中连接词that和what的辨析是高考命题人喜欢利用的考点。
理解这个语法点，能够让小知识发挥大作用，使学生在高考英语备考中事半功倍。
如何才能理解that和what的用法？观察下面这几个句子，让我们从中归纳出一个普遍的规律。
1.What he wants is a book. 我想要的是一本书。
2.That he wants to go there is obvious. 很明显他想去那里。
3.The result is that we won the game.结果是我们赢得了比赛。
4.This is what we want to know.這就是我们想知道的内容。
5.Is what he told us true？他告诉我们的是真的吗？6.We should pay attention to what the teacher is saying.我们应该关注老师正在讲解的内容。
7.I have no doubt that he will come. 我不怀疑他回来。
8.I have no idea what he did that afternoon.我不知道他下午做了什么事。
9.We live in what is called China.我们住在一个被称为中国的地方。
10.What you see is what you get.你所看到的就是你所得到的。
分析以上十个句子，我们不难发现一个规律：从句中缺少句子成分用what，从句中句子结构完整用that。
That只是起到单纯的连接主句和从句的作用，然而what除了连接主句和从句外，还在从句中充当句子成分。
一些英语基础知识薄弱的同学看到这里可能仍然是一头雾水。
what和that的用法区别
the＋名词＋that”或者all that, 即好像是既包括了先行词也包含了
关系代词，因此，有学者称之为关系代词型what。如：
seemed to be a long time, he came up again.
1 _T_h_a_t_ she lacks experience is obvious. 2 The police learned _t_h_a_t _ he wasn’t there at that time. 3 He realized _th_a_t__ she too was tired. 4 My idea is _t_h_a_t you shouldn’t have left the country. 5 Bob has the mistaken idea _th_a_t_tomorrow is a holiday. 6 It was quite plain _t_h_a_t_ he didn’t want to come. 7 It is natural _t_h_a_t_ they should have different views.
that—从属连词
主语从句 宾语从句
引导_名_词__性_从__句___， 表语从句
_不_充__当__句子成分， 同位语从句
_没_有____字面意义。
引导宾语从句的 that可以省略
1 _W__h_a_the had hoped at last came true. 2 China is no longer _w_h_a_t_ it used to be. 3 I’m sorry for _w_h_a_t_ I said. 4 That’s _w_h_a_t_ I want to know. 5 It was _w_h_a_t_ he meant rather than w__h_a_t he said. 6 There’s something in _w_h_a_t_ he says. 7 200 years ago, they came to _w__h_a_t we call “America” now.

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.2)The truth is that Ididn’t go there.3)The news that our team has won is true.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: He made it quite clear that he preferred to study English.(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: 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。
)2．不作成分that 在名词性从句中不作任何句子成分。
Eg. 1)Sydney kept hispromise that hewould always doanything he couldfor Lucie to makesure of herhappiness.（that引导同位语从句）2)That you don’t likehim is none of mybusiness. (that引导主语从句）3．没词义that 在名词性从句中没有汉语意思。
Eg. 1)That she is a rich woman is known to us. (that 引导主语从句)2）The thought that he might fail in the exam worried him. (that引导同位语从句）二．在引导名词性从句时，what一般要注意一个有（meaning）,一个作（component）：eg.1) What I had for breakfasttoday was rice with egg.(what 在句中引导主语从句，what是had的宾语)2）I wonder what we can do. (what引导宾语从句，在句中做do的宾语）3) This is what she wanted to show us. (what引导表语从句，在句中做show的宾语）三．两个注意：1. What所引导的从句可以在介词后作宾语，而that从句一般不可以。
Eg：After months of voyage, Columbus arrived in _____later proved to be a new continent.A. whereB. whichC. whatD. that评析：答案是C。
因为在介词in 后面，应该用what引导的宾语从句，what在宾语从句中作主语。
He was astonished to find the floor covered with _____looked like tiny insects.A. thatB. somethingC.what D. anything评析：答案是C。
因为在介词with 后面，应该用what 引导的宾语从句，what在宾语从句中作主语。
2.that可以引导定语从句，但what不可以引导定语从句, what只引导名词性从句。
Eg:All _____I want to know is what he meant.A.thatB. whichC.what D. whatever评析：答案是A.本题是that 引导的定语从句。
而what 不可以引导定语从句。
又因为先行词是all，故其后不可以接which 引导的定语从句。
______impressed me most was ______such a little boy could play the violin so well.A.That ; whatB. What ;that C. That ; that D.What ; what评析：答案是 B.第一空是what 引导的主语从句，并在主语从句中作主语。
第二空是that 引导的表语从句，that在表语从句中不省略，不作成分，也没词义。
练习：一．改错题：1.What we all like him is certain.2.He left is certain.３．I wished that we could go to Beijing this summer and we could buy some books on our way back4.His delay is due to the fact the car went wronghalfway.5.The idea which the world may be destroyed by nuclear weapons came to him.6.The news our team has won is true.7.He said that he had madea big mistake and he felt very sorry for it.8.The reason he did not come is he was ill.9.His delay is due to the fact the car went wrong halfway.10 .When you answer questions in a job interview ,please remember the golden rule: Always give the monkey exactly that he wants.Key s: 1.(what→That) 2.(he 前加that) 3.（在and 后加that）4.（在the car前加that） 5.(which→that)6.(在news 后加that )7.(第一个that可以省略，但第二个that不可以省略。
所以要在and 后加that) 8.（在is 后加that)）9.（在fact后加that）10. (将that 改what)二）高考题：11．[92] It worried her a bit ______ her hair was turned grey.A. whileB. thatC. ifD. for 12．[93] _____ he said at the meeting astonished everybody present.A. WhatB. ThatC.
