1. Mr. Brown is talking to some volunteer conservationists.
“I want everyone to listen , please. First of all, I′d like you to divide into three groups. Each group should take five plastic bags. Once you have filled a bag, come back to me as you will need another. I need group one to walk along the shore. Group two should check the sand, and group three has to check among the . Mr. Jones is going to collect all the bags and take them to the dump. Mrs. Smith has kindly provided a picnic lunch for us, but we won′t eat until the area is clean. If you can′t find your place, I will help you get there with this map. Don′t worry. … uh … I′m disappointed that people have spoiled this area. However, we are here to do something about this pollution. We must all work very hard. And, if we work hard, we′ll make this a clean and beautiful place again. OK. Now, let′s get started.”
