though
单词辨析：
通常置于句首并用于正式场合，不能像 though 那样用于省略句或引出倒装语序的让步状语从句。
Although it was dark, he still worked in the field.
天黑了，他依然在田里劳作。
We bought the car although it was old.
虽然这辆车是旧的,我们还是买了下来。
作此义解时，只用于倒装语序结构中，语气强于 although 和 though。
Hard as he works, he can't support his family.
他工作努力，可还是无法养活一家人。
Pretty as she is, no one likes her.
她很美丽，但没人喜欢她。
在文体上不如 although 正式，常用于省略句，或引出倒装语序的让步状语从句。
Though (he is) living alone, he is very happy.
他虽然一个人生活，但很愉快。
Though (he is) certainly not a lady-killer, he is still very attractive.
他虽然还不至于让女人一见倾心，却很有魅力。
Strange though it may sound, I was pleased it was over.
尽管听起来也许很奇怪，但我很高兴这都结束了。
