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:
Poor though / as he is , he is happy.虽然他穷,但过得很愉快。
Child though / as she was, the actress was drawing a crowd. 尽管还是个孩子,这个女演员却引起了人们的注目。(child前无冠词a)
3. although 引导从句常指事实,而though 引导的句子可表假设。如:
Let's start as arranged though it rains tomorrow. 即使明天下雨,咱们也按预定的计划出发吧。(假设)
He was not unhappy although he had to live alone. 虽然得一个人生活,他毫无不快之感。(事实)
4.although 只用作连词,而though 除作连词外,还可用作副词,常置句末,句子较长时,也置于句中。如:
It's hard work, I enjoy it though. 这是苦差事,可我干得颇有乐趣。
There's no excuse, though , for hurting her feelings. 伤到她的感情一事,还是不可原谅。
5.though 可用于even though, as though 等结构,although则不能。如:
Even though I fail, I'll keep on trying. 我纵然失败,仍会继续尝试下去。
You look as though (=as if ) you know each other. 看起来你们好像彼此认识。
6. although 和 though 用作连词时不能和but连用,但可跟yet, still 等连用。如:
Although he lives alone, yet he is happy. = He lives alone, but he is happy. 他虽然单独生活,但很愉快。
