1、    May I have your attention，please? I have a few things to tell you．When you have classes here in the language lab，please be here a little earlier，Change your shoes before entering the lab．Don't bring anything else except your textbooks．When you are in，Please don't touch the machines without permission．Always do as the teacher tells you to．In class you could only speak English，not Chinese．You can use the recorder to make a copy of the listening materials．When class is over，turn off your machines and leave the lab one by one．
