Question

三道英语语法题（急急急~在此先谢谢大家了~~~今晚至凌晨1点前在线等）

1.The children went home from the grammar school,their lessons ( ) for the day.
2.The children went home from the grammar school,for their lessons （ ） for the day.
3.The children went home from the grammar school,all of them ( ) their lessons for the day.
A finishing B finished C had finished D were finished

Answer 1

1. B
逗号后面为独立主格结构，独立主语their lessons和动词finish之间为被动关系，所以答案选用其非谓语形式即过去分词finished

2. D
for为连词，引导原因状语从句。选项为该从句的谓语，同样因为their lessons和finish之间的被动关系，所以使用被动结构：be + 过去分词finished

3. A
解释同第一题，因为前后两部分之间用逗号隔开，但是却没有连词，说明其后也是独立主格结构。
但是独立主语all of them和finish之间是主动关系，所以使用现在分词finishing做非谓语成分。
如果两部分之间是句号，则答案为C。
