A、On a bicycle trip. B、Toa recycling center. C、To a paper mill. D、On a business trip. B

W: I’ll go over to the recycling center this after noon. Would you like me to take your old newspaper and paper bags along?
M: I do have a lot of papers and magazines down in the basement. Volunteers used to come by these apartments regularly to collect waste paper. I still save it. But people seldom ask for nowadays and I’ve never gone over to the recycling center myself.
W: That’s typical. A few years ago, people were really enthusiastic about reusing waste paper. Unfortunately, interests have been decreasing lately. Manufacturers now usc wastepaper for things like they need to find new commercial uses for recycled paper.
M: I suppose things like reading cards, calendars and writing paper could be made from it too. But recycled paper usually has a dingy color, doesn’t it?
W: Well, it wouldn’t be suitable for art books or high-quality magazine paper.  But who cares about the drab color if the waste paper can take the place of the virgin woods, pulp and so help to preserve forests.
M: You are right. I’ll bring my waste paper over to your apartment a little while. Thanks for offering to take it.
