【要义详析】
一、概念
在主从复合句中充当表语的从句, 叫作表语从句。它常位于系动词之后, 用来说明主语的身份或特征。
二、连接词的用法
1. that引导的表语从句。
用法: ①无意义 ②不充当句子成分 ③不可省略
*The trouble is that she has lost his address.
麻烦的是她弄丢了他的地址。
*My suggestion is that we should tell him.
我的建议是我们应该告诉他。
2. whether引导的表语从句。
*The question remains whether they will be able to help us.
问题还是他们能否帮我们。
3. 连接代词who/whom/whose/what/which引导表语从句, 在从句中作主语、宾语、表语和定语。
*He is no longer what he was. 他已经不再是以前的样子。
*The problem is who is fit for this job.
问题是谁适合做这个工作。
*The problem is whose work is the best.
问题是谁的工作是最好的。
4. 连接副词引导的表语从句。
*The problem is how we can find him.
问题是我们如何找到他。
*That’s where you are wrong.
那就是你不对的地方。
5. because, as if/as though等引导的表语从句。
*He looked as if he was going to smile.
他看上去好像要微笑。
*That’s because you can’t appreciate music.
那是因为你不会欣赏音乐。
三、注意事项
1. why和because引导的表语从句的区别。
That’s why. . . 意为“那是……的原因”, 强调结果
That’s because . . . 意为“那是因为……”, 强调原因
*I didn’t phone her, and that’s why she got angry with me. (强调她生气的这一结果)
我没有给她打电话。那就是她生我气的原因。
*I didn’t phone her, and that’s because I got angry with her. (强调没打电话的原因)
我没有给她打电话。那是因为我生她的气了。
2. reason作主语或主语中包含事件的起因时, 后面的表语从句表示原因时, 要用that来引导, 而不是because。
*The reason why he was absent from work was that he was ill. 他没来上班, 因为他病了。
3. 表语从句中的虚拟语气。
在表语从句中, 表示间接的命令、要求、请求、建议、决定等, 主句中的主语通常是: advice, suggestion, proposal, request, order, idea等, 从句谓语形式是“should+动词原形”(should可以省略, 但不可换成would)。
*My suggestion is that we (should)start early tomorrow.
我的建议是我们明天早出发。
