know.也是现在完成时么?怎么用?
know是一般现在时
过去式knew 过去分词known 现在分词knowing
be known as 以...知名; 被认为是; 称为
be known for 因...而著名
be known to 为...所知
当be known as被翻译成“以...知名”时,和 be known for的意思是一样的,用法上没有区别.
只有当be known as被翻译成“被认为是; 称为 ”和be known for的意思有区别.
造句:
China is known as the Great Wall.中国以长城而知名.
Paris is known for the Eiffel Tower.巴黎因埃菲尔铁塔而著名.
Chicago is known as 'the windy city' 芝加哥被称为风之城.

是动词原形。
