问题描述:

the workers worked all day ,but they never() A,stopped working B,stop working C.stopped to work

A,,
停止正在做的事情

A,停止干活

从句子的时态上可以看出这句话用的是一般过去时,排除B.stopped working是“停止工作”的意思.stopped to work是“停下来去工作”的意思.因此选A.
stop doing sth 和 go on doing sth 用法一样,而 stop to do sth 和 go on to do sth 的用法一样.

stop to do 是停下手中的事,去做另一件事
stop doing 是停下所做的事
