Question

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

Answer 1

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。
