表语从句举例解析（表语从句综合知识）(三)as if/though like...(主要构成主系表结构)The question is whether Tom can arrive in Beijing on time. 问题是Tom能否准时到达北京。(一)that(不作成分，无实际意义，书面表达不省略，口语表达较常省略)The decision is that Tom is to leave Guangzhou for Beijing tomorrow. 决定是Tom明天离开广州去北京。(二)whether(不作成分，翻译为"是否"，不能省略，一般不用if替代)

一、定义

从句在主从复合句中作表语，则称之为表语从句。表语主要用于修饰主语，构成主系表结构，删除后句子结构意义皆不完整。延伸为表语从句时，也是用于修饰主语，不可删去。注意表语从句的语序是陈述语序。

The discussion is how we can solve the problem. 讨论内容是我们如何解决这个问题。(how引导表语从句)

二、引导词/连接词

(一)that(不作成分，无实际意义，书面表达不省略，口语表达较常省略)

The decision is that Tom is to leave Guangzhou for Beijing tomorrow. 决定是Tom明天离开广州去北京。

(二)whether(不作成分，翻译为"是否"，不能省略，一般不用if替代)

The question is whether Tom can arrive in Beijing on time. 问题是Tom能否准时到达北京。

(三)as if/though like...(主要构成主系表结构)

1.It looks as if the cat is getting fat. 这只猫看起来好像变胖了。

2.It looks like Tom is going to be late. 看来Tom要迟到了。

(四)because(表语从句的主语不能是reason/cause)

It's because Tom caught a cold yesterday. 这是因为Tom昨天感冒了。

(五)其他连接词

1. 连接代词

who which what whom whose whoever whatever whichever...

That's what Tom wants. 那就是Tom所想要的。

2. 连接副词

why where when how whenever wherever...

That's where we played basketball yesterday. 那就是我们昨天打篮球的地方。

三、注意点

(一)That's why和That's because

1.强调结果: That's why Tom was late for work yesterday. 那就是Tom昨天上班迟到的原因。

2.强调原因: That's because Tom didn't catch the early bus yesterday. 那是因为Tom昨天没有赶上早班车。

3.The cat ate nothing. That's ____ it was sick. (填because，强调猫不吃东西的原因是它生病了)

(二)当主语是the reason时，表语从句的引导词 用that，不用why

The reason is that Tom left Guangzhou yesterday. 原因是Tom昨天离开广州了。
