听力原文：M: Hello. This is Greg Rice reporting live in Barrow. Alaska.

W: Hello. Greg. Is everything going smoothly？

M: Yes. I've just arrived here in Barrow. Alaska, to bring you live coverage of what appears to be the results of a huge meteorite impact, perhaps the largest in recent history, that occurred just twelve hours ago. The exact location of the impact is unknown, but estimates put it about 20 kilometers south of Barrow based on shock waves felt throughout the region.

W: Are there any witnesses？

M: Yeah. Some witnesses say they saw a bright light streaking through the sky, accompanied by a mating boom, moments before the impact. It's unknown whether there are any casualties, but it is unlikely considering this sparsely populated area.

W: It's said that such impacts were commonplace during the formation of our solar system, and many believe that a meteorite 10 kilometers in diameter which crashed into Earth 65 million years ago led to the mass extinction of many animal species including the dinosaurs.

M: You're right. But R is often difficult to calculate the number of such large impacts on Earth because erosion and vegetation make it difficult to spot them. In recant years, astronomers have focused more of their attention on the paths of many uncharted space rocks or asteroids floating out there in the hope that we might be able to determine the threat they pose on mankind...This is Greg Rice reporting from Alaska.

W: Thanks, Greg...We'll keep you up-to-date on any development there.

(23)

A．An alien spacecraft landing.

B．The impact of a meteorite.

C．A volcanic eruption.

D．The blizzard conditions in Alaska.

听力原文：M: Hey, Jane. What's so interesting？

W: Oh, hi, Tom. (19)I'm reading this fascinating article on the societies of the Ice Age during the Pleistocene period.

M: The Ice Age？ There weren't any societies then, just the bunch of cave people.

W: That's what people used to think. (20)But a new exhibition at the American Museum of National History shows that Ice Age people were surprisingly advanced.

M: Oh, really？ In what ways？

W: Well, Ice Age people were the inventors of languages, art and music as we know it. And they didn't live in caves. They built their own shelters.

M: What did they use to build them？ The cold weather would have killed almost all the trees, so they couldn't have used wood.

W: In some of the places with warmer climate, they did build houses of wood. In other places, they used animal bones and skins or lived in natural stone shelters.

M: How did they stay warm？ Animal skin walls don't sound very sturdy.

W: Well, it says here, that in the early Ice Age, (21) they often faced their homes towards the south to take advantage of the sun, a primitive sort of solar heating.

M: Hey, that's pretty smart.

W: Then people in the late Ice Age even insulated their homes by putting heated cobble stones on the floor.

M: I guess I spoke too soon. (22)Can I read that magazine article after you've done？ I think I'm going to try to impress my anthropology teacher with my amazing knowledge of Ice Age civilization.

听力原文： Although the practice of the old Roman religion disappeared many centuries ago, some traces of the Roman gods are still present in our daily vocabulary. The names of the Roman sun god, Sol, and the moon goddess, Luna, are used frequently in our language.

The word solar describes anything pertaining to the sun, and lunar anything pertaining to the moon. For example, the sun and the planets circling it are called the solar system. The period of time in which the earth circles the sun once is a solar year. The moon takes one lunar month to circle the earth. A lunar year of twelve lunar months is eleven days shorter than a solar year.

In some cases our language shows how these heavenly bodies affect us directly. A room or place for sunbathing is often called a solarium. We get our word parasol from the Italian word meaning "a guard against the sun". For many centuries it was believed that the moon affected people who were mentally ill. For this reason people who were mentally ill were often referred to as lunatics.

(30)

A．Planets.

B．The moon.

C．The sun.

D．Gods.

听力原文：Astronomers have spent hundreds of years searching for signs of life on other pla

听力原文： Astronomers have spent hundreds of years searching for signs of life on other planets, using telescopes. When they saw the geography of Mars, they thought they could see canals and that this might be evidence of intelligent life on the planet. More recently, however, spacecraft have been sent to analyze the soil for signs of life. The results were negative and astronomers are now convinced that no life exists on the surface of any other planet in our solar system. To send a spacecraft far beyond our solar system is not realistic because of the huge distances involved.

The only way we are likely to know of its existence is from radio messages unless life comes and visits us. Listening for intelligent life is not a new idea, but the techniques now being used to offer much better chance of success than before. Looking for evidence of life in other solar systems now means using special radio receivers called radio telescopes to listen out for messages. The assumption is that intelligent forms of life would have discovered radio waves and would, like us, be using them to communicate.

Through its research work, astronomers have developed two means of systematically searching for intelligent life. The first method is to select the closet 800 stars like our sun and to direct a radio telescope to scan each one of them for electromagnetic waves. The second way is to survey the entire sky, listening for continuous signals. All this, as well as the chance of discovering that maybe we are not alone in the universe!

(29)

A．Intelligent life.

B．Canals of some kind.

C．Signs of life.

D．Natural resources.

听力原文：Those who use solar energy help us save our precious fuel. As you know, our suppl

听力原文： Those who use solar energy help us save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. And when Mother Nature says that's all, that's all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, such as the sun.

We won't have to worry about the sun's running out of energy for another several billion years or so. Besides being an endless source of energy, the use of the sun has other advantages as well. For example, the sun does not offer pollution as other energy sources.

Furthermore, owners of solar homes will have extra protection against rising fuel costs. They will also have some protection against fuel shortage. When utility costs go up, owners of solar homes won't have to face the burdens brought about by increased costs.

With all these good points, why don't we see more of solar power？ There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy around. Solar costs are starting to equal the costs of oil and electricity. And experts say that gas will triple in cost in the next few years. In fact, gas is in such short supply right now that, in some places, it is not sold to new customers. Some customers are even having their supplies cut back.

(33)

A．Rising fuel costs to limit the use of it.

B．Saving energy and use other sources.

C．Having protection against fuel shortage.

D．Putting in a solar unit in every house.

听力原文： Modern Chinese use the solar calendar as English people do. But at the same time, they use their own lunar calendar. Each lunar year is given the name of one of these animals: the rat, the ox, the tiger, the hare, the dragon, the snake, the horse, the goat, the monkey, the chicken, the dog and the pig. This list lasts for twelve years and then starts again.

Each Chinese month starts on the day of the new moon, and the full moon cames on the fifteenth day of the month. The New Year always starts between January the twenty first and February the twentieth.

On the last day of the lunar year, there is a big family dinner. All members of the family (except married daughters) try to be present at this meal, even if they have to travel many miles to reach the home of their parents. Old quarrels are forgotten, and everybody is happy. After the dinner, the children keep awake to welcome the New Year.

The New Year celebrations last for 15 days, from the new moon to the full moon. On the first day, children and unmarried people go to visit their elders.

(30)

A．It was the year of the ox.

B．It was the year of the snake.

C．It was the year of the tiger.

D．It was the year of the hare.

听力原文：You can tell the age of a tree by counting its tings. But these records of a tree

听力原文： You can tell the age of a tree by counting its tings. But these records of a tree's life really say a lot more. Scientists are using tree tings to learn what's been happening on the sun's surface for the last ten thousand years. Each ring represents a year of growth. As the tree grows, it adds a layer to its trunk, taking up chemical elements from the air. By looking at the elements in the rings from a given year, scientists can tell what elements were in the air that year.

Dr. Stevenson is analyzing one element, carbon—14, in rings from both living and dead trees. Some of the rings go back almost ten thousand years to the end of the Ice Age. When Stevenson followed the carbon--14 trail back in time, he found carbon—14 levels change with the intensity of solar burning. You see the sun has cycles. Sometimes it bums fiercely. At other times it's relatively calm. During the sun's violent periods, it throws off charged particles in fast moving streams, called solar winds. The particles interfere with the formation of carbon—14 on earth. When there is more solar wind activity, less carbon—14 is produced. Ten thousand years of tree rings show the carbon—14 level rises and falls about every four hundred and twenty years. The scientists concluded that solar wind activity must follow the same cycle.

(30)

A．To find out the origin of carbon- 14 on Earth.

B．To analyze the composition of different trees.

C．To look into the pattern of solar wind activity.

D．To examine the chemical elements in the Ice Age.
