答
As we all know，know 这里是动词
well-known是固定用法
答
As we all know 这里的as是连词，表示 正如。。。 连词后面要加完整的句子。
as is well-known 这里的as是代词。代词可以作主语。所以。。
as we all know,as is well-known to everyone是固定用法。表示 众所周知
答
As we all know 、as is known to all、as is well-known 是正确的表达
你看 we know 这是主动的形式吧 表示我们大家都知道
而as is known to all是一种表示被动的 被大家所知道 所以要用分词形式
