(2)表语从句

就是在连系动词之后作表语的从句。引导表语从句的连接除与引导主语从句的连接词外，还有as if， as though。如：

The question is whether he is able to do it alone. 问题是他能否单独做这件事。

It looks as if (though) it is going to snow. 天好像要下雪似的。

注意：要区分以下句式：

1. that’s why+结果;that’s because+原因。2. the reason why /for…is that…

He is absent. That’s because he is ill. 他缺席，这是因为他生病了。

He is ill. That’s why he is absent. 他病了，这就是他缺席的原因。

The reason why he is absent is that he is ill. 他缺席的原因是他生病了。
