问题描述:

After ____ her homework, she went shopping.
A finish doing B finish do C finishing doing
选哪个答案,为什么?

选A after doing sth

选C,after是介词,后面要接动名词,finish doing sth

介词后面规定接动词时要用动词的ing形式。
after在...之后,是介词,所以选C。

C, afer介词后跟动词的ing, finish doing sht.做完某事

C AFTER是介词,后面的动词要用ING 形式,而FINISH DOING STH 是固定用法
