interest什么时候是可数,什么时候是不可数?

Question

要详细，有例句。

Answer 1

1.兴趣（不可数）He has a particular interest in Italian art.
2.引起注意的（不可数）places of interest：The city has a multitude of museums and places of interest.
3.爱好（可数）Tell us about your interests and hobbies.
4.利息（不可数）You will repay the money with interest, as agreed in the contract.
5.利益（可数）All he cares about is protecting his own interests.
还有些不常用的意思不用管啦，也许一辈子见不到。

表示“兴趣”时为不可数，表示“利息”时为可数。其次“place of intrests"用复数，意为”名胜古迹“。
