Though：虽然，尽管。多用于口语，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。例如：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。
用though时，可将强调的词前置，但although不能。如：Poor though he is,he is happy.虽然他穷，但过得很愉快。Child though 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）
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）
