听力题 M: How do you and your housemates like the new co-op? I''m thinking of joining it myself. W: We like it quite a bit. We get some very fresh produce and bulk staples of fair prices, but it certainly hasn''t saved us time. M: Then, what''s for? W: Well, the co-op doesn''t carry everything, such as cleaning supplies, battery, that sort of thing. I wish the co-op sold those items. M: What do members have to do? Just pay a membership fee? W: Yeah, there''s a fee and a meeting, but the attendance isn''t required. But we do have to work there for an hour every week, which isn''t too bad. M: I wouldn''t mind working there some time. You get to learn about the products. But is the food free of additives? That would be the main reason I join. I''m a convert (皈依者) from junk food. W: Well, a lot of food is pure and pesticide-free. They also have vitamin supplements, and soy and tofu, and that kind of thing. M: I''d like to try just for a month or so. Do they have trial membership? W: Their shortest membership time is one month. Then if you like it, you can join for longer periods and it becomes cheaper. M: Could you give me some details about the longer periods of membership? W: Oh, I can''t remember the exact regulations, but a six-month membership costs almost as much as five individual months. M: Sounds pretty easy. Maybe the next time I run into you, it will be in the checkout line at the co-op. W: Yeah, if you are interested in it, just join it! M: I will. Thanks a lot. W: Not at all.
