热和功的区别在于热是一种传递中的能量，而功不是。

May I have you attention please? I have few things to tell you. When you have class here in the language lab, please be here a little early. Change your shoes before enter the lab. Don’t bring anything here except your text books. When you are into, please don’t touch these machine without permission. Always do as the teacher tell you to. In class you should only speak the English, not Chinese. Recorders can be used make a copy of the listening materials. When class over, turn off your machines and leave the lab one by one.

That’s all. Thank you.
