be
famous
for;be
famous
as
这一对短语都是“以……而出（著）名”的意思，但它们会在含义和用法上有区别。
(1)当主语是表示人的名词时，be
famous
for表示“以某种知识、技能、作品或特征而出名”，be
famous
as
则表示“以某身份而出名”。试比较：
Einstein
was
famous
for
his
Theory
of
Relativity.爱因斯坦以他的相对论而著名。
Einstein
was
famous
as
a
great
scientist.爱因斯坦以一位伟大的科学家而著称。
(2)当主语是地点名词时，be
famous
for
表示“以某种特点（产品）而出名”；be
famous
as
则表示“以什么样的产地而出名”。如：
Scotland
has
many
lakes
and
mountains,
and
is
famous
for
its
beautiful
countryside.苏格兰有许多湖泊和山脉，并以其乡村美景著称。
The
area
is
famous
as
a
green
tea
producing
place.这个地区以绿茶产地而出名。
(3)当主语是事物名词时，be
famous
for表示“以其内容、特征、价值等而被人所知”；be
famous
as
则表示“以某种形式出名”。如：
This
grammar
book
is
famous
for
its
practical
usage.
这本语法书以其实用性而被人所知。
This
book
is
famous
as
a
reference
book.这是一本有名的参考书。
总之，be
famous
for后的介词是主语的所属内容，而be
famous
as
后的介词宾语则与主语是同位成分。
