题目内容：

词组 be considered as 和 referred to as 的区别,
主要是用法的区别，

优质解答

前者可以理解为“被认知”,即客观的认识
后者可以理解为“被称作”,即主观的判断
例：
He is recognized as leader of the team.他作为领袖被XXX认知（客观事实）
Topics which can be discussed freely within a culture are referred to as small talk.在同一文化中可以高谈阔论的话题我们就称之为闲聊.（主观判断,可能不是）

追答：

不好意思，快下班时候回答的，急了！ consider as 是主观认为，后面接的往往是带有感情色彩的名词短语。 主被动形式都有 例句： By this means he came to be considered as a very trusty protector of his master'sproperty. 通过这种方式，他开始被认为是主人忠实的财产守护者。 refer to as 把……称作; 被称为，后面接的往往是抽象、概述性名词，感情色彩淡些 多用主动结构 例句： This stretching of capacity is what most people refer to as stress. 这种伸展的能力就是大多数人称为的压力。
