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.

希望能解决你疑问

finish后跟动名词。这里building是动名词

我们在一个月前已经完成了修建这个房子的工程。

问：想知道We finished building this house a month ago.的语法时态构成。finished 应该是过去时，后边接building这是一种固定用法吗？为什么用building而不是原型或过去分词？
答：首先，We finished building this house a month ago.的主谓宾状刚好齐全。finished为过去式，所以该句为过...

building this house 动名词作宾语和动名词作主语一样。这是一个过去时简单句。finished 表过去动作。
