Chinese Practice

今天我在公司用中国文。我用中国文帮我的同事。我很高兴。
现在我开暖气机。这几天冷机了。可是里火车太热了。

I think that says: "Today I used Chinese at work. I used Chinese to help my workmates. I'm stoked. I've turned on my heater. It's been frickin' cold these few days. But in the trains it's really hot."

I'm sure I've boobed some of those characters.. and grammar. Meh, I've only just started learning..
