1. 作连词时意思为“尽管、虽然”，用来引导让步状语从句，一般位于句首。它所引导的从句不能与并列连词 but, and, so 等连用，但可以与 yet, still等词连用。
例如：Although it was expensive, we still decided to buy it.
虽然它很贵，我还是决定买。
Though we only stay there for a few days, we had a good time.
虽然我们只在这里呆了几天，但我们玩的很愉快。
2. though除了作连词外，还可以作副词，作“可是，然而”；而 although 不行。
例如：It was hard work; I enjoyed it, though.
这是个艰苦的工作，然而我喜欢。
巧辨although与though
1.两词同义并可换用，但although语气较重，通常放在句首并用于正式场合。如：
I'd quite like to go out, (al)though it is a bit late. 我很想外出，虽然为时稍晚。
Although it was snowing, it was not very cold. 虽然下着雪，但并不很冷。
2.用though 时，可将强调的词前置，但although 不能。as也有此种倒装结构。如：
