聽力原文： In many businesses, computers have largely replaced paperwork, because they are fast and do not make mistakes. Many banks put advertisements in the newspaper showing that their business deals are "untouched by human hands" and therefore safe from human temptation. Obviously, computers have no reason to steal money. But the growing number of computer crimes shows they can be used to steal. Computer criminals don't use guns. And even if they are caught, it is hard to punish them because there are no witnesses and often no evidences. A computer cannot remember who used it; it simply does what it is told. One clerk at a New York City bank used a computer to steal more than one and a half million dollars in just four years. No one noticed this because he moved money from one account to another. Each time a customer he had robbed questioned the balance in his account, the clerk claimed a computer error, then replaced the missing money from someone else's account. This clerk was caught only because he was gambling. When the police broke up an illegal gambling operation, his name was put in the records. Most computer criminals have been minor employees. But police wonder if this is true. As one official say, "I have a feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing--the ones who really know how a computer works."

聽力原文： For centuries, parrots have been prized pets because of their strange talent for imitating human speech. They are able to hear vocal ranges, memorize the tones, and then repeat what they have heard. Often this skill is used to entertain people. But recently, an Amazon parrot, named Baby, was able to put this ability to work by helping police break up a gang of burglars responsible for over $ 50,000 in property theft.

Baby helped the police to identify the gang of thieves. A recent robbery victim reported to the Baytown, Texas police that her parrot, Baby started acting strangely and saying new phrases after the robber y. Before the robbery, Baby had only a twenty - eight vocabulary; afterwards, the bird started saying the additional phrases "Come back, Robert !" and "Come here, Ronnie!".

The police detectives were delighted. Although one man had al ready been arrested, Ronnie and Robert were the names of their two top suspects who were believed to have aided the first man. Under questioning, this suspect explained what had happened. When the robbers entered the house, they heard Baby talking and thought that someone was home. Ronnie and Robert began running away, while the third man yelled for them to come back. Baby remembered this incident and recorded their voices in her memory.

聽力原文： Foxes and farmers have never got on well. These small dog-like animals have long been accused of killing farm animals. They are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them.

But some people who take part in hunting think of it as a sport; they wear a special uniform. of rod coats and white trousers, and follow strict codes of behavior. But owning a horse and hunting regularly is expensive, so most hunters are wealthy.

It is estimated that up to 100,000 people watch or take part in fox hunting. But over the last couple of decades the number of people opposed to fox hunting has risen sharply. Nowadays it is rare for a hunt to pass off without some kind of confrontation between hunters and hunt saboteurs. Sometimes these incidents lead to violence, but mostly saboteurs interfere with the hunt by misleading riders and disturbing the trail of the fox's smell, which the dogs follow.

This year supporters of fox hunting face a much bigger threat to their sport. A Labour Party Member of the Parliament, Mike Foster, is trying to get Parliament to approve a new law which will make the hunting of wild animals with dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in Britain.

Rich people in Britain have been hunting foxes

A．for recreation.

B．to limit the fox population.

C．in the interests of the farmers.

D．to show off their wealth.

聽力原文：[Professor] Now, let's have a look at the bees. Until recently, we knew almost nothing about how important bees are in maintaining natural diversity. Now we know more about them. We know, for example, that honeybees are the dominant pollinators because they play a role in pollinating four out of five food crops in North America. We also know that honeybees, along with the other insects, bats, and birds that transfer pollen between flowers, all together they contribute more than ten billion dollars a year to fruit and see production on North American farms.

[Student A] Wow, It's amazing. Pollination is so important for farming. [Professor] Yes, it is very important. Pollination is one of nature's services to farmers. Just imagine about this: if we don't have the pollinators, we would not have enough food to eat. We biologists never imagined we'd see the day when wild plants or crops suffered from pollinator scarcity. But, unfortunately, that day has come. In factor, farmers in Mexico and the states are suffering the worst pollinator crisis in history. So... what happened? Any idea?

[Student A] Is it... um... because of natural enemies? I read something about a kind of parasite that's killed lots of bees.

[Professor] It's true. An outbreak of parasite mites has caused a steep decline in North American populations of honeybees. But parasites aren't the only factor.

[Student B] What about the pesticides used on farms? All those chemicals must have an effect.

[Professor] Most definitely, yes. Pesticides are a major factor. Both wild and domesticated bees are in serious trouble because of pesticides. In California, farm chemicals are killing around ten percent of all the honeybee colonies. Agriculture in general is part of the problem. Think about this for a minute, the North American continent is a vast collection of "nectar corridors" made up of flowering plants. Is there anybody who knows anything about these corridors?

[Student A] Yes. These corridors stretch for thousands of miles, from Mexico to as far north as Alaska.

[Professor] That's right. And every year, there's an array of migratory pollinators flying north and south with the seasons, following the flowers. The migratory corridors, the flyways... are like... uh... something like a path of stepping stones for the pollinators, with each "stone" being a collection of flowering plants. But our system of large scale agriculture has interfered. During the past fifty years millions of acres of desert in western Mexico and the southwestern United States have been turned into chemically intensive farms, planted with exotic grasses, creating huge stretches of flyway that are devoid of nectar producing plants for migratory pollinators. What we have now are huge gaps between the stepping stones... patches of plants here and there. A couple of migratory pollinators are worth noting. One is the lesser long nosed bat, and another is the most famous pollinator... what is our most famous pollinator? Or I should say our beautiful pollinator.

[Student B] Oh, I know. It's the monarch butterfly!

[Professor] The monarch butterfly...yes. Millions of monarch butterflies all over the U.S. and southern Canada fly south every year in late summer. The monarch is the only butterfly that returns to a specific site year after year. Unfortunately the herbicides used on the milkweed in the Great Plains are taking a toll on monarchs, and fewer of them are reaching their winter grounds in Mexico. Another important pollinator is the long nosed bat. These amazing animals feed on cactus flowers. What they do is, they lap up the nectar at the bottom of the flower, and then when the bat flies off to another cactus, the pollen stuck to its head is transferred to that plant's flower. But the long nosed bat is having a tough time, too. Some desert ranchers mistake them for vampire bats, and they've tried to poison them, or dynamite the caves where they roost.

29. What is the ta

A．The economic importance of bees.

B．A decline in pollinator populations.

C．How flowers are pollinated.

D．Nature's services to farms.

聽力原文： Scientists say sharks have lived in the world's oceans for millions of years. Scientists say there are more than three- hundred-fifty different kinds of sharks.

(14[B]) Sharks do not have bones, and a shark has an extremely good sense of smell. It can find small amounts of substances in the water, such as blood, body liquids and chemicals produced by animals. Sharks also sense electrical and magnetic power linked to nerves and muscles of living animals. These powerful senses help them find their food. Some sharks will eat just about anything. Many unusual things have been found in the stomachs of some large sharks. They include shoes, dogs, a cow's foot and metal protective clothing.

About forty percent of the different kinds of sharks lay eggs. The others give birth to live young. (15[C]) Some sharks carry their young inside their bodies like humans do.

Scientists are beginning to understand the importance of sharks to humans. (16[B]) Medical researchers want to learn more about the shark's body defense system against disease. They know that sharks recover quickly from injuries. Sharks appear never to suffer infections, cancer or heart diseases.

What is this passage mainly about?

A．Call On people to protect sharks.

B．Point out the living environment of sharks.

C．Explain why the sharks are dangerous.

D．An introduction to sharks.

聽力原文：M: Did you know that astronauts have made commercial products in space?

W: No, I wasn't aware of that. What kind of products?

M: Tiny plastic beads with a little hole through it.

W: Tiny balls? Do you mean to tell me that astronauts have nothing better to do than make jewelry beads in space? It seems to me they could make more useful things out there.

M: Oh, but these little balls aren't for jewelry. They can be used for scientific purposes to conduct cancer research .

W: That sounds better, but why make such objects in space rather than on earth?

M: Because earth gravitational pull affects the beads. They produced on earth are distorted, not exactly tumid. The ones made in space are precisely round.

W: Sounds reasonable.
