be well know as be well know to be well know for 1 作为什么而出名 2 对谁出名 3 以什么出名
我的答案和Williamsteel一样，完全赞成他的观点他分析得很对 AS有由于什么什么的意思 TO有对什么，或者为什么 BE FOR有以什么的意思
e well known as be well known to be well known for 1 作为...而出名 2 对...出名 3 以...因为...出名, Chairman Mao Zedong was well known as an great political leader .(作为) Chairman Mao Zedong was well known for his Chinese character writing.（因为） Chairman Mao Zedong was well known to people in the whole world.（对）
抱歉，似乎有一个错误，三个短语都应该是“be well known...”be后面要接形容词形式的。至于改后的解释，完全同意楼上的！
as后面接的是状语 to后面接的是动词短语 for后面接的是名词短语
