请问可不可以互换,如果不可以的话是为什么?

work for work at work in1.he is working for a big firm2.tony worked in a lawyer's office years ago3.he is now working at a bank请问可不可以互换,如果不可以的话是为什么?
不可以
work for是为...工作
work at/in是在某某地方工作
至于用at还in,就要看后面的名词了

我觉得这三个可以互换，意思是一样的~~

这三个明明都是动词吗，不明白你要怎么换。还有啊这个：work for work at work in 完了吗？

同意1楼，

work for 是指你为谁工作的
work at 是指工作的地点
work in 有几中意思呢，可以是地点，也可用是从事的职业哦。还可用是引进，配合的意思呢
