用法说明
03
though和although在从句中不能与but连用,但可以与 副词still和yet连用。

06

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。
