Teacher: We will have our English class in the computer lab next week.
Students: Wow, that's great.
Teacher: You need to follow the computer lab rules. We always follow the terms of the Internet Use Policy. Don't install software in the computers.
Students: Ok, We'll remember that.
Teacher: What's more, Don't bring food and drinks to the lab. Don't hit or bang on the keyboard. Before you leave the lab, be sure to push in your chair and hang up your headphones. Can you obey the rules?
Students: Yes, we can.
