问题描述：
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
选C 为什么
答
C. finished 这是 过去分词的独立主格结构 作状语
相当于一个状语从句 = after their lessons was finished for
the day.
答
说的是孩子们从语法学校回来了，今天的课程结束了。是一般陈述，不用完成时，用一般过去时。
答
楼主,
c 因为他们这个课程已经完成了动作并没有延续到现在或未来,所以排除b...d a就不用说了把我
求楼主采纳,绝对正确,小弟什么都不牛,就英语最牛
