although 与 though的用法区别

三、用于习语

as though(好像)，even though(即使，纵然)等固定短语，不能换成although。

We felt as though we had witnessed the whole thing. 

我们感到仿佛目击了整件事似的。

He is an honest man, I must say, even though I have opposed him. 

尽管我反对过他，我还得说他是一个诚实的人。

四、用于倒装

当though用于倒装形式，它不能换成although，但可换成as。

Try though / as I would, I could not make her change her mind. 

不管我多努力，也不能让她改变主意。  　　

注意，若倒装后置于句首的是名词，其前习惯上不用冠词或其他限定词。

Expert though / as he was, he failed. 

他虽是专家，但还是失败了。
