以下是引用junwang286在2005-4-16 12:49:00的发言：

自己总结的,

be known as + Noun

be known to do

be known to be + Adj.

不知道对不对?

S+be known as sth.:S must parallel with sth.

S+be known to do :S do the action "to do ",and sb. else do "known"

S+be known to be +adj.:S be adj. and sb. else do "known"

we can choice one of the above basing on the mean needed rather than  concrete phrase.

wellcome to discuss.

有个想法，答案既然说是"the best answer" not "the correct answer",那么或许可以认为从语法现象上来讲D未必不正确，但是ETS更倾向于B的表达。

看了几遍之后，今天突然想到除了可能的固定用法外的另一个用to be的理由，大家参看OG9，在解释believe to be 时，ETS先说那是固定用法，之后有一段解释是：当表述一个已经发生很久了，但最近才刚刚被发现的事情时，用to be 比较合适。。。这题不正好符合这条吗？！

be known as sth. 所以用-ing表动名词，我是这么觉得

而satellites now known as 是省略了satellites (that are) now known as

而be known to后面应该跟do, sth被认为，被公认为××

[推荐]known as/for/to do sth

Here's how we should use these:

1. Known to do something: Usually, we say "known to do sth" in two different ways. First, when we want to talk about some fact that people have learned. We also use this when we are talking about the habits of someone or someting that other people know about
Examples:
Smoking cigarettes is known to cause cancer.
Pandas are known to be an endangered species.
Tommy is known to come late to class sometimes.

2.known for:  We use "known for" when we want to talk about the reputation of something.
Examples:
The pomo of California were known for their basket making.
New York City is known for its tall buildings and busy lifestyle.
Dolphins are known for their intelligence and playfulness.

3. Known as: We use "known as" when we want to talk about the name of somebody or something or its definition.
Examples;
In some parts of the United States, the lynx is known as a puma.
An irrational fear, one that has no basis in experience, is known as a phobia.

希望能对你有所帮助.

能不能请楼上的注明一下来源啊，虽然看得出是你经过千辛万苦找到并复制粘贴的。

也好让我们判断一下可靠性！

我在牛津辞典第六版找到know as的应为释义。如下：

1～ sb/sth as sth｜～ sb/sth for sth [usually passive] to think that sb/sth is a particular type of person or thing or has particular charateristics：  Is's known as the most dangerous part of the city.

2～ sb/sth as sth [usually passive] to give sb/sth a particular name or title: The drug is commonly known as Ecstasy.这种致幻药通常被称做摇头丸。

倒是在1中，字典紧接着就给出了know to的例句，但就是没有know to的英文释义。如下：

He's known to be an outstanding physicist.

以下是引用ssophie在2005-2-27 19:45:00的发言：

solome ：不知现在再回贴是否有帮助，我做49题时是通过be known to do sth为切入点，且be通常省略。

以下know as 与know to 的用法供参考。

1.know somebody/something as something :  to have a particular name
example: The main street between the castle and the palace is known as 'the Royal Mile'.

2.know somebody as something

example:Many people knew him as a local businessman.

3.be known to do something:

example:Smoking is known to increase a person's risk of developing lung cancer.

4.know somebody/something to be something
example:It's a story that I know to be true.

sourceDOCE

我的愚见：

known A as B: 那么A=B（可能B的外延大一点但是基本和A是对等的）：

Many people knew him as a local businessman.------〉him 就是一个 a local busi

In some parts of the United States, the lynx is known as a puma.---------〉lynx就是puma

A和B一般都是n。

经常使用的一个缩写A.K.A（also known as）：n1, A.K.A n2, v...........也说明A和B是基本相等的两个东西。

know A to be B: B > A。B的内涵可以比A大得多，以至于绝对不是相等的：

It's a story that I know to be true.---------〉这个story属于true的东西，但是true的东西多了。实际上B是在修饰A，这句如果不是要表达我知道这个含义，完全可以写成It's a true story。

同时know A to be B也可以和know A as B表达差不多的意思：

Also she knew Shill to be a toper and, when in his cups, a man of violence.

尽管如此似乎known as比较常用

Known to do，看了很多文章，极少（我是没有）见到known as+doing的，known as就像是给一个东西下定义，不能把一个n.定义为v.ing吧。如果要表达人们知道什么东西在做什么，就应该用known to do，这样不但合乎语法、逻辑，还简洁。

同时似乎GMAT中如果出现都符合语法的情况，不定式较动名词/现在分词一般也是个优选项

如：the time required to assemble...就比the time required for the assembling of....优先（见OG11-44）。
