Lily: I can’t bring drinks and snacks to the computer room, although I like to have them after class. If I do so, the teacher will not let me in.

Jack: I must keep quiet or talk in a very low voice. When I have any problems, I must raise up my hands to ask my teacher for help.
Tom: I enjoy computer games very much at home, but I can’t play them during the class. If I do so, the teacher will let me out.

A．Keep the computer room clean. Don’t wear your dirty shoes into the computer room.

B．Keep quiet in the room. If you don’t, your teacher and others will be angry with you.

C．It’s not right to bring anything to eat to the room. They can make the room and computers dirty.

D．Don’t answer the phone or listen to music in the computer room, because they have nothing to do with your study.
