human与human being意思相同,均表示“人”,但是用法上有区别:
1、human强调“人群”,human being强调“个人”。
Its rate of growth was fast — much more like that of an ape than that of a human.
它的发育速度很快——更像猿,而不像人。
Each human being has to die, but mankind goes on world without end.
每个人都会死,但人类却永无止境。
2、在一些惯用的表达,两者不能互换。
例如疾病的“人传人”叫human to human transmission,但不可以说human being to human being transmission。
3、human可以做形容词,human being不可以。
human作为形容词意思是人的;有人性的;显示人类特有弱点的;人本性的。
The computer doesn't mimic human thought; it reaches the same ends by different means.
计算机并没有模仿人的思维,而是通过不同的手段达到了相同的目的。
