英语CLOSEDiamonds's value lies in their hardness,not their beauty,and in the thousands of ____ they do.A.jobs B.works C.duties D functions为什么要选A 不选D
function表示功能的时候是不可数名词 function不可与thousands of连用
do a (good) job的意思是完成了一件什么事,实现了什么作用
这句话的意思是,钻石的价值不在于它的坚固(硬度),不在于它的美丽,也不在于它能干什么.(即有多少实际作用)

job是名词,可以直接作do的宾语
work和function都可以做动词表示起作用,在没有强调的时候,没必要用do work和do function的结构
另外,work作名词一般不用复数

偶刚看完也想选D,呵呵,不懂解释

function 主要指电器的功能,是实际概念.而A有抽象意义
