Conversation Two
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, [23]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. [24]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 environmentand disposable chopsticks are a big waste of forest resources. [25]Well, there will be a lecture tomorrow 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(huán)保活動，最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(huán)境問題。選項A、D都是圍繞B項內(nèi)容展開，只是對話的部分內(nèi)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(jié)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(huán)境污染的嚴重性。因此，答案應(yīng)該是D。其他選項都是具體做法，而且不完全與該運動相關(guān)。本題答案所在的句子較長，信息量大，考查學生的基本功?？忌綍r應(yīng)有意識地多聽長句，熟悉其結(jié)構(gòu)組成，考試時遇到方能得心應(yīng)手。
25. What will the woman do tomorrow afternoon?
正確答案：A
解析：細節(jié)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。
