（2）作连词，后接从句，引导时间状语从句。例如：

直到父亲回来，那个孩子才睡觉。

4. Although shes wrong, its not a big deal.
although作连词，相当于though，意为尽管，虽然，用来引导让步状语从句。它所引导的从句不能与并列连词but; and; so等连用，但可以和yet; still等词连用。例如：

（1）用作连词，表示虽然，二者可以互换使用，但although比though更为正式。例如：

虽然下着雨，但我们还是去了那里。
（2）although一般不用作副词，而though可用作副词，且一般放在句末（不放在句首），意为可是，不过。例如：

工作很辛苦，可是我很喜欢。
We all tried our best. We lost the game, though.
我们都尽力最大努力，但我们还是输了。

I hope you to go. (误) 我希望你去。
（3）两者都可接that从句，但是hope + that从句表示希望，wish + that从句表示愿望，且从句的谓语动词要用虚拟语气。例如：
I hope youll be better soon. 我希望你很快好起来。
I wish I were really wealthy. 但愿我真的富有。
（4）wish后可接双宾语。hope没有这种用法。例如：
