| ( At the beginning of the trip to Mount Hood) J=Jack L=Lynn S=Sue J: OK, everybody. I'm very glad to lead the team. Are we all ready? L: Wait! Has everyone put on sunscreen? S: Oh, dear! 1 L: Here you are. Use mine. Put on some quickly. It can stop the sun from hurting your skin. S: Thank you. J: 2 especially because this is Sue and Lynn's first time to have such a trip. L: All right, Jack. J: Rule number one, don't walk by yourself. We don't all have to stay together, but don't go somewhere by yourself. S: No problem. 3 J: OK. And rule number two, keep the mountain beautiful. 4 Don't litter around. We want others to be able to enjoy this beautiful place, too. L: I know what you mean. 5 . J: Well, those are the two most important rules. If I think of anything else, I'll tell you on the way. So let's go! All: Yeah! All right! Let's go!
