虛擬語氣考點 表語從句

考點4 表語從句

表語從句在句中作表語，位于主句中的系動詞之后。除that, whether和疑問詞外，as if, as though, because也可引導(dǎo)表語從句。

The question is whether she can speak English. 問題在于她是否會說英語。

That is what we need. 那正是我們所需要的。

It looked as if it was going to rain. 似乎要下雨了。

注意

① why與because 均可引導(dǎo)表語從句，但前者強調(diào)結(jié)果，后者強調(diào)原因。

I had a cold. That’s why I didn’t come. 我感冒了，所以我沒有來。

I didn’t come. That’s because I had a cold. 我沒有來，因為我感冒了。

② 主句的主語是reason時，表語從句要用that，不能用because。

The reason why we didn’t go was that we were notified too late.

我們沒有去的原因是我們得到通知太晚了。
