区别:
be interested in+(doing) s.th—后接名词,固定搭配,意思是对什么东西对人很感兴趣。其主语应该是人或其他有生命的东西。
be interested to+ do s.th—后接动词,没有单独的这个结构,只有intersting to do sth或that,除非是放在句子里,有特定的语境,不能单看。
例子:
I'm interested in working in the US.(我对在美国工作很感兴趣)
I am interested in reading English novels.(我对读英语小说很感兴趣)
He is interested in listening to stories. (他对听故事很感兴趣)
I am interested to know what happens. ( 我很想知道发生了什么事)
I am interested to read more about his life.(我很想知道更多关于他的妻子)
We’d be interested to hear your story. (我们很想听听你的故事)
