英语自学网

　　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。
        　　7.though 常用于省略句。如：Though (he is) alone, he is happy.
