1、be famous for 因……而著名

表示人“以某种知识技能，作品或特征而出名”，表示某地“以某种特产或特征出名”，或表示某事“以其内容、特征、价值等而被人所知”。如：

2、be famous as 作为……是出名的

主要是表示人“以某种身份或职业而出名”，或表示某地方“作为什么产地或地方而出名”，或表示某事物“以某种形式而出名”。如： 

Mark Twin was famous as a children-story writer. 马克·吐温作为儿童故事作家而著称。

This book is famous as a reference book. 这本书作为参考书而出名。 

He is famous as a writer.作为一个作家他是有名气的。

二者的区别如下：

He is famous for his great inventions.  因为他的伟大发明，他出名了。

He is famous as a great inventor. 他是出了名的伟大的发明家。

2、当主语是表示地点的名词时，be famous for表示“以某种特点(产品)而出名”，be famous as表示“以什么样的产地/地方而出名”。

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表示“以某种形式出名”。

二、as的用法

1、 as作连词的用法:

（1）作"当……的时候",引导时间状语从句。注意与when、 while的用法区别。

① when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间。如:

When the clock struck twelve, all the lights in the street went out.

② while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。如:

Work while you work. Play while you play.

③ 但属下列情形时,只用as, 而不用when或while。

A) 用于表示同一个人的两种动作交替进行,指"一边……,一边……"。如:

The girl dances as she sings on the stage.

He looked behind from time to time as he went forward.

B)表示两个同步发展的动作或行为,译为"随着……"。如:

As time went on / by, she became more and more worried.

Just as the flying worm hit her face, she gave a loud cry.

D) 后接名词表示某一年龄段时,用as。如:

As a young man, he was active in sports.

（2）as=since, 作"既然"、"由于"解,引导原因状语从句,常用来表示已为人们所知或显而易见的原因或理由。如:

As / Since you're not feeling well, you may stay at home.

As he wasn't ready in time, we went without him.

（3）as=in the way that, 作"像"、"按照……的方式"解,引导方式状语从句。如:

He speaks English as Americans do.

Remember, you must do everything as I do.

（4）用于as...as...或not so/ as...as...中,前一个as是副词,后一个as是连词,引导比较状语从句。如:

They helped the old man as often as possible.

I don't speak English so/ as well as he does.

（5）作"虽然"、"尽管"解,引导让步状语从句。常用倒装语序,即adj. /adv. / n.+ as +主语+谓语+主句。如:

Tired as they were, they walked on.

Child as he is, he knows a lot. (child前不用冠词)

2、 as作关系代词,引导定语从句,作"正如"、"这一点"解。如:

He is very careful, as his work shows.

As is well-known, Taiwan belongs to China.

另外,当先行词被the same, such等词修饰时,常用as来引导定语从句。如:

Such a clever boy as he can learn anything quickly.

I was reading the same book as he bought yesterday.

3、 as作介词的用法:

as引导的介词短语大多用作状语,as译为"作为";少数情况可引起宾语补足语。如:
