原文： 任何事物都有两点，说只有一点叫知其一不知其二。
译文： There are two aspects to everything; to say there is only one is aware of one aspect and ignorant of the other.
【正确答案】：改译：There are two aspects to everything; to say there is only one is to be aware of one aspect and to be ignored of the other.
【题目解析】：本题考查的是不定式的用法。不定式在英语中使用频繁，可以做除谓语外的其他成分。本题中，不定式既用作主语，又做了表语。原句的译法不符合英语的语法规则。
