一、详细释义：

（尤用于句末补充说明，使语气减弱）不过，可是，然而

例句：

例句：

例句：

例句：

（用于主句后，引出补充说明，使语气变弱）不过，可是，然而

例句：

例句：

二、词义辨析：

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：可引出倒装语序的让步状语从句，although 则不能。可与even连用，although则不能；在as though结构中，只用though，不能用although。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。

三、参考例句：

He answered firmly though pleasantly.

他的回答虽和气，但语气坚持。

Reliable data, though, are scarce.

然而可靠的数据还是很少。

She behaved as though nothing had happened.

她表现得若无其事。
