working in and working for?

首先你應用 I HAVE, 而不是 I HAS

文法上這兩個句子都無問題的:)

不過WORKING IN多數會跟 A 一齊用:

I AM WORKING IN A PUBLISHING COMPANY.
我正在一間出版社工作。

反而WORKING FOR會跟 MY 一齊用多:

I WORK FOR MY COMPANY FOR ALMOST 3 YEARS.
我在我的公司工作了差不多3年。

不過其實任何一個都可用的:)

**第2句例句有錯**
應該是:

I HAVE BEEN WORKING FOR MY COMPANY FOR ALMOST 3 YEARS.

You should you "I has been working in this company for 3 years"!!!
Why???

Meaning:
Working in means you are just doing a job in that company(You are a worker)
Working for means you are very helpful to that company , you try your best and you are thinking something good to that company. (Mabye you are a higher level person)
I am very sorry
