  • 答案选D独立主格结构主要用于描绘性文字中,其作用相当于一个状语从句,常用来表示时间、原因、条件、行为方式或伴随情况等.例如: 表示时间  The meeting being over, all of us went home. 开完会后我们都回家了.   Her work done, she sat down for a cup of tea. 她干完了活,坐下来喝茶. 表示条件  The condition being favourable, he may succeed. 若条件有利,他或许能成功. 表示原因  There being no taxis, we had to walk. 没有出租车,我们只好步行.
