it's still early.Why not _your homework?A.finish doing B.fin

A.
首先why not ,why don't you后面加动词原形do.固定搭配.
然后finish doing sth.结束;做毕 .
英文释义：When you finish doing or dealing with something, you do or deal with the last part of it, so that there is no more for you to do or deal with.
例句：
As soon as he'd finished eating, he excused himself...他一吃完就告辞离开了.
Mr Gould was given a standing ovation and loud cheers when he finished his speech...
古尔德先生结束演讲后,全场起立鼓掌并热烈欢呼
不像stop,remember,begin即可加doing,又可加to do,finish没有finish to do的用法.

选A
Why not do sth(动词原形)
finish doing sth (动词的动名词)

1. why not do=why don't you do
2, finish sth. 或者finish doing sth.
所以选A

A

finish doing 固定结构 后面不能接to do

A
why not后面跟动词时，跟动词原形。而finish这个词，可作及物动词，也可做不及物动词。
