May I have you attention please? I have a little things to tell you. When you have a 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 to making a copy of the listening materials. When class over, turn off your machines and
leave the lab one by one.
