听力原文： If the earth gets hotter, what will happen to animals and plants which animals depend on for survival？ The question offers another way of looking at the "Greenhouse Effect". People have talked about the general problem of "Global Warming" for some time. But they were usually worried about things like whether to buy a home on the coast. Biologists and other scientists turn their attention to plants and animals last October. They review evidence that plants and animals are sensitive to climate. Since the Ice Age ended and warmer temperatures returned to the northern latitudes, many species have migrated north. If the predictions about the Greenhouse are correct, temperatures will rise by the same a-mount in the next one hundred years as they did in the past ten thousand. Will animals and plants be able to adapt that quickly to change in the environment？ Many won't. Certain species will become rare. Experts say plants under climate stress will be very open to disease and fire. Forest fires may become more common. That, in turn, may harm animals that depend on the trees for food or shelter. Any preserves we set up to protect endangered species may become use-less, as the species are forced to migrate along with their natural homes. Change is a part of life, but rapid change is the enemy of life.
What is the concern of ordinary people about the "Greenhouse Effect"？

听力原文：M: Hi, I heard you are looking for a different apartment.
W: Yeah, the place I am in is really terrible.
M: It was OK when I was there.
W: The boiler keeps breaking and when it does, we lose the heat for several days at the time.
M: Why does not the owner replace it？
W: Well, she said it's cheaper to keep fixing it. She is a nice enough person, just sort of stingy in any case. I'm sick of being cold.
M: Can you get your deposit back if you move？
W: If 1 give a 2-month notice, I can get the whole thing back.
M: So what kind of place are you looking for？
W: I think I'll try to get into one of those high rises near the university. There is nothing really special but at least they are new and functional.
M: I heard those buildings are pretty noisy. The walls are thin and you can hear everything going on in the other apartment.
W: Oh, that will never do. I need some place quiet to finish my thesis. I guess I'll have to look at some more ads. Maybe new isn't necessarily better.
M: Why don't you try some of those apartments at Windsor？ They're supposed to be nice.
W: Oh, aren't they awfully expensive？
M: Not really. The problem with being out there is that the bus doesn't run that way.
W: That definitely won't be a problem. I can afford a car right now.
What is wrong with the woman's current apartment？
Which compound noun form. is NOT mentioned in this conversation？
听力原文：M: Let's look at a few things about English. What is a compound word？
W: Two chemicals mixed together？
M: Very funny, but no.
W: TWO words mixed together.
M: Well, yes, in a manner of speaking. A compound word is made up of two or more words that express a single idea. There are different ways that compound nouns can be formed. We are going to concentrate here on the noun plus noun form. Can you come up with any examples？
W: Doghouse, dog plus house. Cupcake, cup and cake.
M: Excellent. There are three different ways to form. this type of compound noun: there is the closed form, in which the words come together as one, such as firefly, keyboard, notebook.
W: Textbook, fireplace.
M: Great. And there is the hyphenated form. ski-boot, daughter-in-law, sin-pack...The last form. of compound nouns is the open form, such as post office, history book, mineral water. Just exactly how and why these three exist is not clear, but it seems likely that the process will begin with two words, become hyphenated after a time, and then eventually end up as just one word. Language is a living thing and always changing.
