【问】 Longman Dictionary of Common Errors说下列句子是错误的：

×If you are interested to know more about the town's history，you should visit the museum.

而必须更改为：

√If you are interested in knowing more about the town's history，you should visit themuseum.

并解释说，interested in+V-ing (有趣于做某事)，而不用to-V(见《朗文英语正误词典》P.193)。请问be interested究竟能不能与to-V(带to的不定式)连用?

【答】 be interested除经常与in sth.或in doing sth.连用外，有时也可与to do sth.连用。be in-terested to do sth.是指“有兴趣做某事”。因此，上面的所谓错句其实并不是什么错句。请看：

他很乐意观看他们的面孔和服装。
