We finished building this house a month ago.
我们在一个月前完成了这栋房子的建筑.
嗯,是固定用法,finished 后面只能接ving
应该说finish后面只能接ving
一个动词后面的动词往往要看第一个动词的脸色
有些动词加to do 有些加ving
finish doing 做完某事
I have finished doing my job.
没有finish to do
make sb do sth.逼使某人去做某事
The boss made the workers work 12 hours a day.
make sth.+adj.
Don't make your father angry.
希望能解决你疑问
