表语从句讲解及专项操练之袁州冬雪创作概念：表语从句是在复合句中作表语的名词性从句.放在系动词之后,一般布局是“主语+系动词+表语从句”可以接表语从句的连络动词有be, look, remain, seem等.★ The trouble is that we are short of money.坚苦是我们资金短缺.★ That is why stone walls are used instead of fences around New England fields.这就是为什么在新英格兰用石头墙而不必栅栏的原因.★ 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，在白话中，间或可以省略.）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.that在引导表语从句时无词义，而whether有词义，意为、“是否”.这时主句的主语常常是些抽象名词，如question(问题)，trouble(费事)，problem(问题)，result(成果)，chance(能够性)，suggestion(建议)，idea(想法)，reason(来由)等.表语从句对主句主语停止说明、诠释，使主语的内容详细化.例如：★ The trouble is (that) she has lost his money. 费事的事是他丢了钱.★ 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 tha t fewer and fewer students showed interest in her lessons. 我们不克不及懂得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.关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句，在句中作主语、宾语、表语，关系代词不克不及省略.例如：★ The question is which of us should go.问题是我们哪个应该去.★ 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 除在句子起毗连作用外，在从句中还充当时间，地点，方式或原因状语，自己具有词义.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.★ 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.那就是老鼠是怎样每一年损害大量食粮的.★ That is what he is worri ed about.那就是他所担心的.※ 由连词because，as if/as though等引导的表语从句.★ It looked as if it was going to snow.看起来好像要下雪了.★ 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.好像他不知道答案.注意A. 表语从句一定要用陈述语序.False: The question is when can he arrive at the hotel.Right: The question is when he can arrive at the hotel.B. 不成以用if，而用whether 毗连表语从句(as if 破例）.引导宾语从句时可以互换if/whether 位于介词后要用whether位于句首时要用whether.引导表语从句，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纷歧致.Right: The question is who will travel with me to Beijing tomorrow.Right: The question is why he cried yesterday.D. that在表语从句中不成以省掉.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)★ 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)★ 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脚本.(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，不克不及省略)★ 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 faile d to pass the exam. 那就是她测验不及格的原因.(why 在表语从句中充当原因状语)表语测试1.

2．引导表语从句的关联词的种类：(1)从属连词that。
在从句中不做成分。
如：The trouble is that I have lost his address.麻烦是我把他的地址丢了。
The reason was that he was late for school.(2)从属连词whether,as,as if。
如：(3)looked just as he had looked ten years before.他看起来还与十年前一样。
(4)question is whether they will be able to help us. 问题是他们是否能帮我们。
(5)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：(6)All this was over twenty years ago, but it’s as if it was only yesterday.(7)这都是20多年前的事了，但宛如昨天一样。
The key is whether we can solve the problem.注：能跟表语从句的谓语动词一般为系动词be, seem, look，sound等。
如：(8)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.连接代词who, whom, whose, what, which, whoever, whatever, whichever 在表语从句中做主语、宾语等。
如：The problem is who we can get to replace her.问题是我们能找到谁去替换她呢。
(9)That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。
The problem is who we can get to replace her.(10)我想问的是谁离开了。
My question is who left.连接副词where, when, how, why。
What I wonder is when he left. 我想知道他是何时离开的。

It's just because he doesn't know her.(13)T hat's because he didn't understand me. 那是因为他没有理解我.(That's because...强调原因)(14)T hat's why he got angry with me.那正是他对我生气的原因。
(That's why...强调结果)(15)在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。
should+动词原形表示，should可省略。
如：(16)M y suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。
二、系动词分类：1、根据系动词后所跟结构，我们可以把英语系动词分为两大类：完全系动词（其后只能跟表语的动词，如be, seem）和半系动词（其后既可跟表语作系动词用法，也可跟宾语或状语作实义动词用，如look）例如：1）He looked sadly at the boy.(“看着”，实义动词用法)2）He looks a clever boy .（“看起来”，系动词用法2、根据系动词的意义，我们把英语系动词分为四类：A．五大感官系动词B．状态系动词C．动态系动词D．双谓语系动词A．五大感官系动词，描述一种感官性质。
