英语中human race,human beings ,mankind用法有何区别??

human being和human race是近意词 其区别实在是很微小，用中文很难解释清楚 因为2者在中文的意思都是人类 但是用英语解释你应该就能明白起定义上的区别了 首先是human being 1. any living or extinct member of the family Hominidae characterized by superior intelligence, articulate speech, and erect carriage 同义词：homo, man, human 例句： 1.
