(英语改错) you must work hard on English and never give up learning it.on为什么要改为at.

问题描述:

(英语改错) you must work hard on English and never give up learning it.on为什么要改为at.

work on sth.就有“直接平面接触”地作用于宾语,具体地改变宾语的状态的意思;
而work at sth.就没有那么具体直接,它只表示“点存在”,
i work at biology
i work on my news article all night
也就是说 at 后面接抽象的名词
on 后面要接具体的名词

固定搭配
work hard at…在……方面努力工作
work hard at sth努力学习
work hard at math在数学上努力
work hard at sth.在…努力
work hard (at)勤奋工作
We must work hard at English.
