1.although/ though意为“虽然” Although I didn't know anybody at the party, I had a good time. 虽然晚会上的客人我一个也不认识，但我玩得很愉快。
注意： "although...but"是个典型的错误，因为but是并列连词，不能与从属连词although连用。但是， although可与yet或still连用，因为yet，still是副词，它可使前后关系更明确。

状语从句的结构和特点
状语从句通常由从属连词引导，从句中的谓语用非谓语形 式（不定式、分词、动名词等）。不同类型的状语从句有 不同的结构和特点，如时间状语从句常用when, while, as 等引导，条件状语从句常用if, unless等引导。
状语从句与并列句、复合句的关系
状语从句与并列句和复合句有密切关系。并列句由并列连 词连接两个或两个以上的简单句，而复合句则包含一个主 句和一个或多个从句。状语从句可以作为复合句中相反的假设条件，主句说明在这个假设条件下会出现的结果。常用if引导， 从句和主句的谓语动词都要用虚拟语气。
