1.although的用法although意思相当于though(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。

如：①although the book was old, we decided to buy it.尽管这本书很旧，我们还是决定买。②there is air all around us, although we cannot see it.虽然我们看见空气，空气却存在于我们的周围。③although princeton has a world-famous university, it is still a small quiet town.普林斯顿虽然有一所世界闻名的大学，但仍然是个安静的小镇。记住,在学习连接词时,一定要弄明白他们是连接副词还是连接代词,连接副词就是副词,不作句子主要成分,连接代词要做句子成分,考试最喜欢考连接代词不仅有连接作用，而且还在从句中充当主语，表语、定语等句子成分。常见连接代词有 who , whom , whose which , what , whatever , whoever连接副词除了连接从句外，还在从句中作状语。常见连接副词有 when , where , why , how。

2　 unless是从属连词，引导条件状语从句，含有否定意义，相当于if条件状语从句的否定形式。所以unless = if not。注意：unless引导的条件状语从句和if条件状语从句，与其它时间状语从句一样，用一般现在时代替将来时。

Unless: conj. 除非, 如果不
