though在句末是人副词，意思是：adv.可是，不过；然而。
它可以放句首，也可以放句末。though引导让步状语从句时表示一种假设的情况或含有推测的意味，从句的谓语动词可用陈述式，也可用虚拟式；有时为了强调让步的意义，可采用倒装语序。在用though连接的从句中，谓语是be，而从句的主语与主句的主语相同时，从句的主语与be可同时省略。
词义辨析：
conj. (连词)
though, although.
这两个词都可表示“虽然”。其区别是：
1、although的语气较重，引导的句子常指事实；though引导的句子可表示假设。
2、though可以引起从句的主语和谓语部分倒装，而although不可。
3、although只用作连词；而though除用作连词外，还可用作副词。另外，though可用作并列连词，也可用作从属连词；而although只能用作从属连词。
4、though可用于even though, as though, what though等结构；而although不能。
词汇搭配：
1、even though 即使。
2、as though 仿佛。
3、even if/though 即使 ......也。
