though

• adv. 可是，虽然；不过；然而
• conj. 虽然；尽管
• prep. 但

though, although, as

这些连词均可表示"虽然，尽管"之意。

though和although在意义上几乎毫无区别，但文体上后者是较正式用词，语气比though强。此外，在习惯用法上这两个词仍有以下一些差异：1.though可引出倒装语序的让步状语从句，although 则不能。2.though可与even连用，although则不能；在as though结构中，只用though，不能用although。3.though可以置于从句末，而although则不能。4.引出省略句时，通常用though。

as： 引出让步状语从句只用于倒装语序结构中，语气强于上述两个连词。
