keep用法It's great you've just finished keeping the book?此句中用k

orrow 是非延续性动词,keep则是它相对应的延续性动词.这句用keeping 比borrowing好.用keeping意思是把书还回去了,borrowing意思则是刚借来.而borrow 的动作是瞬间就完成的,和"finish"连用说不通,似乎“借”的动作持续了很久.所以我认为用keeping才对.

keeping可以
keep是持续动词，borrow是瞬间动词，因此不用borrow

finished doing
borrowing book 应该可以，但是理解起来不太好

borrow 是非延续性动词，keep则是它相对应的延续性动词。
