表语从句要点解读 讲义作为名词性从句中的一个重要内容，有关表语从句考查的题目在历年的高考中频频出现。表语从句在复合句中作主句的表语，对主语的内容加以补充，有时说明主语的状态，它位于主句的连系动词之后。对表语从句的学习我们要注意以下几点：1. 定义及其构成：表语从句放在连系动词之后，充当复合句中的表语，这些系动词有：be， look， seem， sound， appear等。其构成为：关联词+简单句。如：It appears to her that he wants to teach us all he has. 在她看来，他似乎要把他所会的都教给我们。It was because he didn't pass the exam. 那是因为他没有通过考试。It seems to me that we should answer for this. 在我看来，我们似乎应该对此事负责。The question was who had done it. 问题是这件事是谁做的。It looks as if it was going to snow. 天看起来要下雪了。2. 引导表语从句的关联词有：（1） 从属连词that：The trouble is that I have lost his address. 麻烦是我把他的地址丢了。The truth is that I didn't go there. 事实是我没去那儿。The fact is that we are behind other groups. 事实是我们落在别的组后面。（2） 连接代词who， whom， whose， what， which， whoever， whatever， whichever;连接副词 where， when， how， why：My question is who left. 我想问的是谁离开了。What I wonder is when he left. 我想知道他是何时离开的。That's what he wants. 那是他想要的。This is where they once lived. 这就是他们曾经住过的地方。That is why he didn't come here. 这就是他为何没到这儿来的原因。What she wants to know is which dress she should buy. 她想知道的是她应该买哪件衣服。Spring is when the whether is very warm. 春天是天气暖和的时候。（3） 从属连词whether， because， as if 引导的表语从句：Things are not always as they seem to be. 事物并不总是如其表象。It sounds as if someone is knocking at the door. 听起来好像有人在敲门。It looks as if it were going to rain. 天看上去好像要下雨。It is because you eat too much. 那是因为你吃得太多了。3. 几个需注意的问题：（1） 在表语从句中，即使从句有疑问意义，从句的语序也要用陈述句语序：The question is how we'll go there. 问题是我们怎样去那儿。That is why we love our motherland so much. 这就是为什么我们那么热爱祖国的原因。（2） 当主语是reason时，表语从句表原因要用that引导，不能用because;当主语是it， this或that时，表语从句可用because或why引导：The reason is that he didn't understand me. 理由是他不明白我的意思。He couldn't answer you. That was because he knew little English. 他不能回答你，是因为他几乎不懂英语。He knew little English. That's why he couldn't answer you. 他几乎不懂英语，那也是他为什么不能回答你的原因。（3） 使用虚拟语气的表语从句： as if 从句用虚拟语气的情况。当说话者认为句子所述的是不真实的或极少有可能发生或存在的情况时，谓语动词用一般过去时。如：You look as if you didn't care. 你看上去好像并不在乎。 在表示建议、劝告、命令含义的名词后的表语从句，谓语动词需用“should+动词原形” 表示，should可省略。常见的词有：advice， suggestion， order， proposal， plan， idea等。如：My suggestion is that we （should） start early tomorrow. 我的建议是我们明天一早就出发。（4）在表达“是否”这一概念时，要用whether，不用if。如：The problem is whether we need it. 问题是我们是否需要它。跟踪精练与答案I. 结合表语从句的用法，从方框中选择合适的词填空（其中有一项多余）。1.
