It is rather difficult to make friends with him, but his friendship, ________, is more true than others’.
A.once gainedB.when to gainC.after gainingD.while gaining在线课程A
解析:
本题考查状语从句的省略、引导词及非谓语动词的用法。句意为:“很难和他交朋友,但是,一旦获得他的友谊,将会比任何友谊更纯真。”此题应用过去分词作状语表示条件。once gained相当于once it is gained.gain和his friendship是被动关系,所以用过去分词。当条件状语从句的主语和主句的主语一致或主语为it时,可将从句的主语和系动词be一起省略。
