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,一般结构是“主语+系动词+表语从句” 可以接表语从句的连系动词有 be, look, remain, seem 等。 ★ The trouble is that we are short of money.困难是我们资金 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用栅栏 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，在口语中，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， question(问题)， 如 trouble(麻 烦)， problem(问题)， result(结果)， chance(可能性)， suggestion(建
议)，idea(想法)，reason(理由)等。表语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 lessons. 我们不能理解越来越 少的学生对他的课不感兴趣。 ※ 由关系代词引导的表语从句。 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， 关系代词不能省略。 例如： ★ The question is which of us should go.问题是我们哪一个
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 来。就在你原来放的地方。 ★ I had neither a raincoat nor an umbrella. That’s why where you left it. 去把雨衣拿
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年损害大量粮食的。 ★ That is what he is worried 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。 ★ 了。 ★ That's because we never thought of it.这是因为我们从未 It looked as if it was going to snow.看起来好像要下雪
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. 不可以用 if，而用 whether 连接表语从句(as if 例外） 。 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)
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
