高三英语二轮复习表语从句讲义及练习
表语从句概念解析及巩固练习一、表语从句概念解析：什么是表语？什么是表语从句？1.表语是英语区别于汉语所特有的一种词类，是起表述作用的句子成分，它常位于系动词之后，用来说明主语的身份、性质、品性、特征和状态。
表语必须和系动词一起构成系表结构，作为句子的复合谓语。
表语通常由名词、形容词、介词短语、不定式、形容词化的现在分词或过去分词以及从句来充当。
eg. Africa is a big continent. (名词作表语)Our next step was to prepare raw materials.（不定式作表语）The patient is in danger.（介词短语作表语）Who's your best friend? （代词作表语）He is old but he is healthy. (形容词作表语)2.在一个主从复合句中，当从句作的是主句的表语成分时，这个从句就被称为表语从句。
The problem is what we can get from him.My idea is that we should start making preparations as soon as possible.*（1）表语从句一定要用正常语序,疑问句也要用陈述语序。
The question is when he can arrive at the hotel. (正常的陈述语序)（2）主句时态和表语从句时态可以不一致。
The question is why she failed the exam.二、表语从句的连接词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，很多人都弄不清标语的概念，因而也弄不清表语从句的用法引导表语从句的词有连词that, whether，连接代词和连接副词，关系代词型what，以及as if, as though, because等连词。
1. 由that引导（在从句中不作成分）The fact is that he doesn’t really try. 事实是他没有做真正的努力。

It's where you left it. 去把雨衣拿来.就在你本来放的地方.★I had neither a raincoat nor an umbrella. That’s why I got wet through. 我们既没伞也没雨衣,这是我们淋湿的原因.★That is how mice ruin many stores of grain every year.那就是老鼠是如何每年伤害大量食粮的.★ That is what he is worried about.那就是他所放心的.※由连词because,as if/as though等引诱的表语从句.★ It looked as if it was going to snow.看起来似乎要下雪了.★ That's because we never thought of it.这是因为我们从未想过此事.★ It seems as if he didn’t know the answer.似乎他不知道答案.留意A. 表语从句必定要用陈述语序.False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.B. 不可以用if,而用whether 衔接表语从句(as if 破例）.引诱宾语从句时可以交换if/whether 位于介词后要用whether位于句首时要用whether.引诱表语从句,主语从句,同位语从句时要用whether.False: The question is if the enemy is marching towards us.Right: The question is whether the enemy is marching towards us.Right: It looked as if he had understood this question.C.不像宾语从句,在有表语从句的复合句中,主句时态和从句时态可以不一致.Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.D. that在表语从句中不可以省失落.根本用法表语从句只能置于主句之后,而主句的动词只能是接洽动词.名词性从句在be等系动词后作表语时被称为表语从句例如：★The problem is how we can get the things we need.问题是我们如何能弄到我们须要的器械. (how 在表语从句中充当方法状语)★ The scissors are not what I need. 这把铰剪不是我所须要的.(what 在表语从句中充当宾语) ★What I told him was that I would find him a good play. 我告知他的是我会给他找个好脚本.(what在主语从句中作直接宾语,that作为表语从句的引诱词在该表语从句中不充当句子成分,不能省略)★That is what I want to tell you.那就是我想要对你讲的.(what在表语从句中充当直接宾语)★That is why she failed to pass the exam. 那就是她测验不合格的原因.(why 在表语从句中充当原因状语)表语测试1.

宾语从句和表语从句都属于名词性从句。其作用跟名词在句中的作用相同。故充当宾语的句子叫宾语从句，充当表语 的句子叫表语从句。 宾语从句
, 从句 , 从句时
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。 表语从句
在句子中起表语作用的从句叫做表语从句，位于主句系动词的后面。表语从句的引导词和主语从句的引导词相同。也 是名词性从句的一种。

At that time, it seemed as if I couldn't think of the right word anyhow. 当时 ,我似乎怎么也想不出一个恰当的字眼来。 引导表语从句的词： 从属连词 that、 whether、 as though、 as if（ That 引导表语从句时，在口语中，间或可以省略。 ）
D. that 在表语从句中不可以省掉。
基本用法
表语从句只能置于主句之后，而主句的动词只能是联系动词。名词性从句在
be 等系动词后作表语时被称为表语从句
例如： The problem is how we can get the things we need.
问题是我们怎样能弄到我们需要的东西。
(how 在表语从句中充当方式状语 )
(1)对于宾语从句要掌握以下三点 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 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 )。
What I told him was that I would find him a good play. 我告诉他的是我会给他找个好剧本。 (what 在主语从句中作直接宾
语， that 作为表语从句的引导词在该表语从句中不充当句子成分，
不能省略 )
That is what I want to tell you. 那就是我想要对你讲的。 (what 在表语从句中充当直接宾语 ) That is why she failed to pass the exam. 那就是她考试不及格的原因。 (why 在表语从句中充当原因状语 ) 注意
(1) “ That is why... ”与“ That is the reason why... ”同义， 只不过从语法结构上讲， “ That is the reason why... ”中 why 引导的是—个定语从句， 将其中的 the reason 去掉则与“ That is why... ”结构一样， 例如：
从句对主句主语进行说明、解释，使主语的内容具体化。例如：
The trouble is (that) she has lost his money. 麻烦的事是他丢了钱。
The question is whether we need more ice cream. 问题是我们是否还需要一些冰淇淋。 The problem was that it was too valuable for everyday use. 问题是它作为日常之用太贵重了。 What she couldn ’ t understand was that fewer and fewer students showed interest in her lesson我s.们不能理解越来越少的学 生对他的课不感兴趣。 由关系代词引导的表语从句。

The problem was who could do the work. 问题是谁能做这项工作。
That's what he is worrying about. 那就是他在担心的事。 That's what we should do. 那是我们应该做的。 由关系副词引导的表语从句。
关系副词 when, where, how, why 除在句子起连接作用外，在从句中还充当时间，地点，方式或原因状语，本身具有词 义。例如： Go and get your coat. It's where you left it. 去把雨衣拿来。就在你原来放的地方。
The scissors are not what I need. 这把剪刀不是我所需要的。 (what 在表语从句中充当宾语

)。
(前文提

2: feel , seem , look, appear ,sound, taste , smell 3: stand , lie , remain ,keep, stay
4: become ,get , grow , turn ,go ,come, run, fall
5: prove, turn out The trouble is that we are short of money. 困难是我们资金短缺。
表语从句讲解及专项练习
概念： 表语从句是在复合句中作表语的名词性从句。 从句的连系动词有 be, look, remain, seem 等。
放在系动词之后 ,一般结构是 “主语 +系动词 +表语从句 ”可以接表语
可以接表语从句的系动词有：
1： be（being,been,am,is,are,was,were)
“That is why... ”是常用句型， 意为“这就是 ,, 的原因/因此 ,, ”， 其中 why 引导的名词性从句在句中作表语，
型通常用于针对前面已经说明过的u see this old woman before you know, Jeanne. 珍妮， 这就是现在这个老太婆出现在你面前的原因。
I had neither a raincoat nor an umbrella. That why I g ot we’t thsrough. 我们既没伞也没雨衣，这是我们淋湿的原因。

That is (the reason) why I cannot agree. 这就是我不能同意的理由。 (2)“ That is because...”句型中从属连词 because引导的名词性从句在此作表语， 这也是个常用句型， 意为“这就是为 什么 ,, /因为 ,, ”。“ That is because...”与“ That is why... ”之间的不同在于 “ That is because...”指原因或理由， “ That is why... ” 则指由于各种原因所造成的后果， 例如：
关系代词 who, what, which, whom, whose, whatever, whoever, whomever, whichever 等； 关系副词 when, where, why, how, however, whenever, wherever 等。
由从属连词 that， whether 引导的表语从句。

whether 。
