be famous to和be famous for的区别如下：
be famous for 因。。。而闻名， be famous to 相当于be familiar to ，be famous for 和be famous as 都是出名的意思
1.be famous for因……而闻名
The town is famous for its hot spring. 该镇以温泉驰名。
be famous as作为……而闻名
She is famous as a writer. 她是位名作家。
2.be famous to不是一个固定搭配，牛津和朗文字典上均没有收录，只是由于to表示“对于”，所以可以表示““为……所熟知””。
类似的还有
be known for 以……而闻名
be known as 作为……而闻名
同样的，be known to可以表示“为……所熟知”
除此以外，还有be famous as 作为。。。。而出名
