选择题
The children went back home from the grammar school, their lessons ________ for the day.
A.finishing
B.had been finished
C.finished
D.had finished
答案
答案:C
考查独立主格结构。分析题目结构可以看出,“their lessons ________ for the day”部分不能是句子,因为前后都没有连接词。所以空格处应填入过去分词,表示被动和完成意义。“their lessons finished for the day”构成的是独立柱个结构,在句中作状语。
