M: Have you noticed the new dustbin downstairs, at the entrance of the main building?
W: Yeah, of course. It looks funny, though, like a battery. What’s it for? Is it really for garbage?
M: Not really. Actually it’s a dustbin for used batteries.
W: Used batteries? What do you mean by that? Why do we need a special dustbin for used batteries?
M: Well, you know there are still a lot of heavy metals left in used batteries, so by recycling the batteries,[13]we can not only make full use of the metals left, but also prevent the environment from being polluted.
W: Oh, I see. Can this work? Our efforts are too insignificant.
M: Even though we are not ecologists or biologists, there is still a lot we can do. The Student Union is sponsoring a one-month program called "Green Movement", which is aimed at making more and more students aware of serious environmental problems we are facing now.
W: Sounds quite exciting—"Green Movement". What, for example, can I do?
M: Well, quite a lot. For one thing, you can stop using those plastic meal-boxes and disposable wooden chopsticks. Plastic meal-boxes do great harm to the environment and disposable chopsticks are a big waste of forest resources.[15]Well, there will be a lecture tomorrow afternoon at four o’clock. You may attend if you are interested.
W: Tomorrow afternoon…let me think…yeah, I happen to be free. I will go there.
