2016考研英语语法：名词性从句之表语从句

表语从句知识点
表语从句是一种名词性从句，通常放在主句的谓语动词之后，并用逗号将其与主句分隔开来。

表语从句的构成和用法如下：构成：
连词：表语从句通常由连词引导，如that, whether, who, what, why, where, when等。

主语：表语从句的主语可以是名词、代词或者短语。

谓语：表语从句的谓语动词通常与主句的谓语动词相关联，可以是解释、说明、描述、定义、推断等。

用法：
说明主语的身份或特征：表语从句可以用来解释或说明主语的身份或特征，例如：The problem is that we don't have enough funds. (问题是我们没有足够的资金。

)
表示原因或结果：表语从句也可以用来表示原因或结果，例如：The reason why she failed is that she didn't study hard enough. (她失败的原因是她没有努力学习。

)
表达条件或假设：表语从句可以用来表达条件或假设，例如：The situation is that if we have enough funds, we can continue with the project. (情况是如果我们有足够的资金，我们就可以继续这个项目。

)
注意事项：
表语从句的主语和谓语动词必须与主句的主语和谓语动词保持
一致。

在使用连词引导表语从句时，需要注意连词在从句中所充当的成分。

表语从句通常用虚拟语气来表达语气强调，需要根据具体情况选择适当的语气。

名词性从句从句有名词性从句、定语从句和状语从句三大类。

名词性从句又可分为宾语从句、表语从句、主语从句及同位语从句，因为从句的在这个句子中的功用相当于名词；定语从句有称为形容词性从句，因为从句功能相当于形容词；而状语从句则称为副词性从句，因为从句功能相当于副词。

什么是名词性从句?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，由一个句子来充当,这个句子就叫名词性从句。

宾语从句( The Object Clause)表语从句( The Predicative Clause)主语从句( The Subject Clause)同位语从句( The Appositive Clause)表语从句一．定义在句中充当表语的从句(即放在be动词后面)叫做表语从句。

二．构成一般结构是“主语＋关联词＋表语从句”。

Our purpose is that he can realize his faults.我们的目的是他能认识到错误。

注意：引导表语从句的连接词一般不省略。

问题是它是否值得做。

注意：表语从句表示“是否” 只用“whether” 而不用“if”。

三．引导表语从句的关联词的种类1. 可接表语从句的连系动词有be，look，seem，sound，appear等。

China is no longer what she used to be.今日的中国不再是过去的中国了。

At that time，it seemed as if I couldn't think of the right word.当时，我似乎怎么也想不出一个恰当的字眼来。

2. 从属连词whether，as，as if / though引导的表语从句。

He looked just as he had looked ten years before.他看起来还与十年前一样。

It sounds as if someone is knocking at the door.听起来好像有人在敲门。

各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。

上述这四种从句均被称为名词性从句。

所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。

另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。

下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。

例如：That he will come to the discussion is certain.他来参加讨论是确定的。

That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。

When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。

主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。

例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。

考研英语语法篇：表语从句考研英语进入冲刺复习阶段很多同学把经历都转移到了其他灵活性更高的科目中，英语作为一门记忆内容多于理解的学科在冲刺阶段很容易让人忽略他的重要性，但是我们都知道，英语考研试卷其实并不容易拿高分，而前阶段复习的基础知识如果太长时间不去运用也会如利剑生锈，给考试带来麻烦，下面凯程考研英语老师就为大家总结长难句常见语法，希望能给冲刺复习的考生提个醒，将基础融会贯通才是高分的基本法则。

表语从句在句中作表语。

引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用as if引导。

其基本结构为：主语+ 系动词+ that从句。

例如：The fact is that we have lost the game. 事实是我们已经输了这场比赛。

That‟s just what I want. 这正是我想要的。

This is where our problem lies. 这就是我们的问题所在。

That is why he didn‟t come to the meeting. 那就是他为什么不到会的原因。

It looks as if it is going to rain. 看上去天要下雨了。

需要注意的，当主语是reason时，表语从句要用that引导而不是because。

例如：The reason why he was late was that he missed the train by one minute this morning .【注意】whether 可引导表语从句，但与之同义的if却通常不用于引导表语从句。

名词性从句之表语从句宾语从句：从属连词：_______, ______, ______连接代词：______ , _______, _______, ______, ______连接副词：______, ______, _______, ______表语从句的定义：表语从句在复合句中作主句的表语。

表语从句和主语指同一内容，它对主语进行解释、说明，使主语的内容具体化。

其结构是“主语+系动词+表语从句”，可以接表语从句的系动词有be, look, remain, seem等。

A.表语从句的连接词1.从属连词主要有that, whether, as if, as though1)that在从句中不作任何成分，也没有任何具体意思，但是不能像宾语从句那样子省略。

eg: The fact is that he hasn’t yet recover from illness.The reason why he has to go is that his mother is ill in bed.2)whether引导表示“是否”的表语从句，在从句中不做任何成分，但有意思，但在与宾语从句不同，if不能用来连接表语从句。

eg: The question is whether we can rely on him.What the doctor really doubts is whether my mother will recover from the serious disease soon.3)as if和as though引导表示“似乎”的表语从句，在从句中不做任何成分，但有意思。

eg: It sounds as if someone is knocking at the door.She looks as if she were ten years younger．1. The question is ____it is worth visiting.A.ifB.as ifC.whetherD.how2. ___you are the first one here.A. It seems that as ifB. It seems as if thatC. It seems as ifD.It seems that as though3.

He looked ______ he was going to cry .A. thatB. ifC. whetherD. as if2.连接代词what, who, whom ,whose , which. 因为连接代词在从句中担任一定的句子成分，具有一定的意义，所以不可以省略。

英语表语从句表语从句：就是用一个句子作为表语。

说明主语是什么或者怎么样，由名词、形容词或相当于名词或形容词的词或短语充当，和连系动词一起构成谓语。

表语从句是名词性从句的一种。

表语从句的基本结构是：“主语+连系动词+关联词+表语从句”。

连接表语从句的连接词有：that, what, who, when, where, which, why, whether, how,，whoever whomever，whichever，whatever 等。

例如：The question is when he can arrive at thehotel. His suggestion is that we should stay calm.①语序：从句的语序必须是陈述句语序，即“主语+谓语”这种形式。

②时态：当主句是一般现在时或一般将来时的时候，从句可以是任何时态，而当主句是一般过去时的时候，从句，从句时态必须是过去时范围的时态，即（一般过去时，过去进行时，过去完成时，过去将来时）。

③连接词：当从句意思完整，主句意思肯定时，连接词用that，且可以省去，当从句意思完整，主句意思不确定或含否定含意时，常用if 或whether （是否），当从句意思不完整时，连接词则是代替不完整部分的特殊疑问词。

根据关联词来区分,表语从句可以分为六种:一、由that 引导的表语从句The trouble is that he misunderstood 麻烦的me 是他.误解了我。

有时，引导表语从句的连词that 可以省略The truth is (that) I’ didnt finish my term essay 事实. 是我没有写完学期论文。

二、由连接代(副)词引导的表语从句连接代词who, whom, whose, what, which, whoever, whatever, whichever；连接副词where, when, how, 。

英语从句的熟练使用是作文一个强有力的加分项，考研英语也不例外。

在英语中，我们常见的从句有三大类：名词性从句、定语从句、状语从句。

表语从句隶属于名词性从句中的一种，但却常常被考生分不清。

小编今日为大家带来表语从句的类型和词类总结，希望各位考生能够在正式开启考研复习前完全掌握这一知识点。

表语从句是名词性从句的一种，也是往往最令大家迷糊的一种，很多人都弄不清表语的概念，因而也弄不清表语从句的用法，帮帮这次为大家带来表语从句用法大总结，快点学起来吧! ?表语从句的类型 表语从句位于主句系动词之后，可分为两类：be + that型从句和be + 疑问词型从句。

1. be + that型从句 eg. The fact is that we have no idea to solve this problem.事实就是我们没办法解决这个问题。

The reality is that the party must be cancelled because of the storm. 现实就是因为暴风雨这个聚会必须得取消了。

2. be+疑问词型从句 eg. The question is whether they will help us. 问题是他们会不会帮我们。

The problem is why she didn't go back home directly. 麻烦就麻烦在为什么她没直接回家。

3. 表语从句使用陈述语序。

eg. The question is when he can arrive at the hotel. 问题是他什么时候能到酒店。

4. 主句主语是reason时，表语从句要用that引导，不可用becauseause。

但reasons作主语时，表语要用名词短语并列。

eg. The most common reasons for ...... are 名词短语1，名词短语2 and 名词短语3。

考研英语长难句：名词性从句-表语从句表语从句比较简单，通常是将从句置于系动词，尤其是is后面，一般由that, what, why, how, when, where, whether等连词和关联词引导。

表语从句结构：主语+连系动词+句子作表语。

例如:That is just what I want. 这正是我想要的。

That is where our problem lies. 这就是我们的问题所在。

That is why he didn’t go to bed. 那就是他为什么不睡觉的原因。

It looks as if it’s going to rain. 看上去天要下雨了。

英语语法：名词性表语从句上一期学习了，英语语法中的名词性主语从句，就很好理解本期要介绍的名词性表语从句，只是位置从主语的位置换到了表语的位置，其他用法都是相的，所以不应该当作一种新知识来学，只要你会了主语从句，表语从句自然也会了。

英语语法中的从句有：主语从句、表语从句、宾语从句、同位语从句、定语从句、状语从句。

英语从句的重点是，熟悉连接从句的连词、关系词的各种含义和用法。

1.名词性从句英语语法中的名词性从句，是一个在句子中起名词（属性）作用的句子。

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。

所以，根据它在句中不同的英语语法功能，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。

1.2表语从句通常位于谓语和系动词之后，以从属连接词开头。

·连接表语从句的连词纯连词：that, whether连接副词：when, where, how, why连接代词：whatMy idea is that we meet in the bookstore.我的想法是我们在书店里见面。
