听力原文：M: I want to register for this mathematics course.
W: I'm sorry registration has closed.
M: Closed？ The clerk told me I could come back and register any time during the first week of classes.
W: Well, that's not possible. The system has already been closed for almost a week. Who told you that anyway？
M: Some woman here when I tried to register three weeks ago. She said I just had to pay a late fee.
W: She must have been a temporary worker. They don't have much training. Why didn't you register then？
M: She said I couldn't until I had my birth certificate. Here it is.
W: Your birth certificate？
M: Well, I'm a new student. So she asked for identification. And I am not old enough to get an ID card.
W: Huh. That's no reason to demand a birth certificate. We only need to establish residency: a phone bill with your name and address on it would've been fine.
M: Really？ Only proof of my address？
W: Yes. I'm afraid she gave you the wrong information. Still you'll have to wait and take your matt's class next semester.
M: But that's unfair.
W: Well, I sympathize with your problem, but frankly, I don't think there is anything anyone can do for you. You were trapped in the system. If you want to, you can talk to the director. She will help you if she can.
M: Great.
W: Don't get your hopes up, though,

GENETICALLY MODIFIED FOODS
Are genetically modified crops an environmental dream come- true or a disaster in the making？ Scientists are looking for answers.
The world seems increasingly divided into those who favor genetically modified (GM) foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering which can induce plants to grow in poor soils or to produce more nutritious foods will soon become an essential tool for helping to feed the world's burgeoning population. Skeptics contend that GM crops could pose unique risks to the environment and to health risks too troubling to accept placidly. Taking that view, many European countries are restricting the planting and importation of GM agricultural products. Much of the debate hinges on perceptions of safety. But what exactly does recent scientific research say about the hazards？ The answers, too often lost in reports on the controversy, are served up in the pages that follow.
Two years ago in Edinburgh, Scotland eco - vandals stormed a field, crushing canola plants. Last year in Maine, midnight raiders hacked down more than 3,000 experimental poplar trees. And in San Diego, protesters smashed sorghum and sprayed paint over greenhouse walls.
This far - flung outrage took aim at genetically modified crops. But the protests backfired: all the destroyed plants were conventionally bred. In each case, activists mistook ordinary plants for GM varieties.
It's easy to understand why. In a way, GM crops—now on some 109 million acres of farmland worldwide—are invisible. You can't see, taste or touch a gene inserted into a plant or sense its effects on the environment. You can't tell, just by looking, whether pollen containing a foreign gene can poison butterflies or fertilize plants miles away. That invisibility is precisely what worries people. How, exactly, will GM crops affect the environment- and when will we notice？
Advocates of GM, or transgenic, crops say the plants will benefit the environment by requiring fewer toxic pesticides than conventional crops. But critics fear the potential risks and wonder how big the benefits really are. "We have so many questions about these plants," remarks Guenther Stotzky, a soil microbiologist at New York University. "There's a lot we don't know and need to find out."
As GM crops multiply in the landscape, unprecedented numbers of researchers have started fanning into the fields to get the missing information. Some of their recent findings arc reassuring; others suggest a need for vigilance.
Fewer Poisons in the Soil？
Every year U. S. growers shower crops with an estimated 971 million pounds of pesticides, mostly to kill insects, weeds and fungi. But pesticide residues linger on crops and the surrounding soil, leaching into groundwater, running into streams and getting gobbled up by wildlife. The constant chemical trickle is an old worry for environmentalists.
In the mid - 1990s agribusinesses began advertising GM seeds that promised to reduce a farmer's use of toxic pesticides. Today most GM crops—main

听力原文：W: Hello？
M: Hi, May, this is Bill Johns.
W: Oh hi, Bill. You weren't in engineering class today, were you？
M: I have the flu. I was wondering if you could tell me what went on.
W: Actually we had an interesting class. Dr. Collin talked about a new type of fuel.
M: Oh, yeah？
W: Uh-hum. It's called Dimethyl Ether or DME.
M: Oh, I remember reading something about DME. It's mostly used in spray cans, right？
W: Right. DME doesn't destroy the ozone, so it's been environmentally friendly.
M: But doesn't DME pollute the air if it's burned in an engine？
W: Dr. Collin says something about its exhausts being clear, that it doesn't release as much pollutants as diesel fuel. And he mentioned something about DME being more efficient than other alternative fuels.
M: When will it replace diesel fuel？
W: Not for a while. It's not economical to mass-produce.
M: Well, thanks for the information. I guess I won't need to borrow your notes.
W: Well, maybe you should look at them. We are having a test next week.
M: Okay, could you give them to Mike Andrews？ I think he is in your psychology class. He is my roommate.
W: Sure. I hope. you're feeling better soon.
M: Thanks. Me too. Bye!
W: Bye!

听力原文：Woman: Good morning, Richard. Now, in 1994 you were a computer science graduate with a good job working for an investment company . . . and then you started Bookstore. Why？
Man: Well, I was thirty and settled at work, but then I came across a report predicting annual internet growth at 2,300%. The figure was like an alarm clock ringing in my head. I started to think about the regrets I might have at eighty. I realised I probably wouldn't even remember the things that seemed important in my thirties (like getting my end-of-year pay bonus. But I'd definitely tell myself I'd been a fool to ignore the internet.
Woman: How did you go about choosing a product？
Man: Well, I drew up a list of twenty products, from clothes to gardening tools, and from that I got a shortlist of five, and then I assessed them. I thought about market growth in different countries and I also did some research into suppliers. But there were other important factors as well. I wanted a product that didn't retail for too high a figure. I thought that since many people would be buying from the internet for the first time, they might be afraid to take a risk with large amounts of money.
Woman: And what made you decide on books？
Man: Well, basically, I found out that books had an eighty-two billion dollar market world-wide. There's also a high demand for CDs - a product I nearly went for - but with books there's a much wider choice. There're 3 million items in the book category, but only 300,000 in CDs. This choice meant the capabilities of the computer - in organisation and selection - could be put to good use.
Woman: Bookstore has certainly been very successful. Why do you think that is？
Man: Well, it's not been easy. For the first five years, it was a struggle raising funds and developing the right software. The ideas weren't the difficult bit. If you and I sat down here for an hour, we'd come up with a hundred good ideas. The hard bit is making those ideas work. There are several key elements, which for me were research, recruiting the right staff, and prioritising.
Woman: And you're satisfied with your customer growth？
Man: Well, it was a bit slow at first but then it picked up and from May '97 we started to see our greatest growth. We went from a hundred and twenty million dollars annual sales revenue to two hundred and thirty million dollars by the end of that year, and from 340,000 customers to 15 million. 58% of them were repeat customers. By '98, sales had reached almost three hundred and ten million dollars.
Woman: And is Bookstore's success reflected in its profits？
Man: Well, at the moment we're focusing on introducing ourselves to customers and we spend a lot on advertising. Anything else would be a poor management decision. But, of course, it's reflected in our final figures. It's not unusual for a four-year-old company like ours to be in an investment cycle. What is more unusual is for a young company like Bookstore to be sold on the stock market, which happened in July '97.
Woman: Bookstore is well-known for its high- quality customer service. What is the secret of your success in this area？
Man: Well, firstly our books are delivered fast and any complaints are dealt with by email and what's important is that the email is always answered in a friendly way, with the emphasis on 'the customer is always fight'. In fact, customers sometimes feel guilty about complaining because Bookstore staff are so helpful! Regular customers are recognised when they go to our website, and we suggest titles to them, based on their previous purchases.
Woman: Do you think Bookstore offers a better service than its competitors？
Man: Well, yes. We'd been in the market for about two years before most of our competitors started so we had a head start and although some have caught up now, we're still cheaper. Our book price includes tax and delivery. Most of our competitors' prices don't. But what's more important is that B
