　　M: Have you noticed the new dustbin downstairs, atthe entrance of the main building?

　　W: Yeah, of course. It looks funny, though, like abattery. What's it for? Is it really for garbage?

　　M: Not really. Actually it's a dustbin for usedbatteries.

　　W: Used batteries? What do you mean by that? Whydo 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 thebatteries, [23]we can not only make full use of the metals left, but also prevent theenvironment 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. [24]TheStudent Union is sponsoring a one-month program called "Green Movement", which is aimed atmaking 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 anddisposable wooden chopsticks. Plastic meal-boxes do great harm to the environmentanddisposable chopsticks are a big waste of forest resources. [25]Well, there will be a lecturetomorrow afternoon at four o'clock. You may attend if you are interested.

　　W: [25]Tomorrow afternoon... let me think... yeah, I happen to be free. I will go there.

　　Questions 23 to 25 are based on the conversation you have just heard.

　　23. What are the two speakers doing?

　　正確答案：B

　　解析：主旨題。四個選項的話題對話中都提到了，但整個對話由新垃圾箱引出電池回收問題，并進而談到開展環保活動，后男士告訴女士明天有一個講座，可以讓人們更深刻地認識環境問題。選項A、D都是圍繞B項內容展開，只是對話的部分內容，不能用于概括大意，故答案為B。而C錯在collect。

　　24. What is the purpose of the "Green Movement"?

　　正確答案：D

　　解析：細節題。男士提到“綠色運動”，它是學生會主辦的為期一個月的活動，旨在讓更多的學生意識到環境污染的嚴重性。因此，答案應該是D。其他選項都是具體做法，而且不完全與該運動相關。本題答案所在的句子較長，信息量大，考查學生的基本功。考生平時應有意識地多聽長句，熟悉其結構組成，考試時遇到方能得心應手。

　　25. What will the woman do tomorrow afternoon?

　　正確答案：A

　　解析：細節題。男士說明天下午有個講座，如果有興趣的話可以參加。女士回答說，明天下午正好有空，會去的，所以答案為A。符合“聽到什么選什么”的原則。C是長期行為，不是明天下午要做的事。
