听力原文:Not, long ago, some of you may have read about the team of mountain climbing scie

ntists who helped to recalculate the elevation of the highest mountain in the world, Mount Everest. Of course the elevation of Mount Everest was determined many years ago using traditional surveying methods. But these scientists wanted to make a more pre else measurement, using a new method that takes advantage of recent advances in technology; it's called the Global Positioning System. The Global Positioning System uses 24 satellites that circle the earth. Each of the satellites is constantly sending out signals, and each signal contains important information that can be used to determine the longitude, latitude and elevation at any point on the earth’s surface. Well in order to use the system to calculate a mount of Everest's elevation, scientists need to put a special receiver on the summit to receive signals from the satellites. The problem with this was that in the past, the receivers were much too heavy for climbers to carry. But now these receivers have been reduced to about the size and weight of a hand held telephone, so climbers were able to take the receiver to the top of the Everest, and from there, to access the satellite system signals that would allow them to determine the precise elevation. And it turns out that the famous peak is actually a few feet higher than us previously thought.

听力原文: We can read of things that happened 5000 years ago in the Near East, where people first learned to write. But there are some parts of the word where even now people cannot write. The only way that they can preserve their history is to recount it as sagas—legends handed down from one generation to another. (29)These legends are useful because they can tell us something about migrations of people who lived long ago, but none could write down what they did.

(30) Anthropologists wondered where the remote ancestors of the Polynesian people now living in the Pacific Islands came from. The sagas of these people explain that some of them came from Indonesia about 2000 years ago.

But the first people who were like ourselves lived so long ago that even their sagas, if they had any, are forgotten. So archaeologists have neither history nor legends to help them to find out where the first 'modern men' came from.

(31) Fortunately, however, ancient men made tools of stone, especially flint, because this is easier to shape than other kinds. They may also have used wood and skins, but these have rotted away. (31)Stone does not decay, and so the tools of long ago have remained when even the bones of the men who made them have disappeared without trace.

(30)

A.They moved from one place to another.

B.They came from Indonesia.

C.They have left us information about their migrations.

D.They preserved their sagas and legends.

听力原文: When men first lived on the earth a long time ago, they had no proper place to live in. In order to get away from the heat of the sun, to keep themselves warm and dry, they found caves. Caves really gave them some kind of help. Some of these early men built their shelters up in the tree to escape wild animals. They had a hard life and had to go about from place to place for food. Much later on, their lives began to change. They learnt how to keep animals in herds. As they had to move their herds of animals from place to place for grassland, they had to build shelters which were easily carried about.

When they finally learnt the art of farming, they had to clean forests and started planting crops. After that, they had to think about building more permanent shelters. Old houses were built at first with wood and they even use grass as roofs. This went on for a long time. They kept making their houses better. Today, houses of all kinds are built. They are strong, permanent and can last a very long time.

(30)

A.To get away from the heat of the sun.

B.To keep themselves warm.

C.To get away from the rain.

D.To keep themselves dry.

听力原文:Brighton is a popular seaside town on the south coast of England. Not long ago so

听力原文: Brighton is a popular seaside town on the south coast of England. Not long ago some policemen at Brighton were very puzzled. There had been several serious accidents caused by motorists driving too fast. The police started to set up a speed trap. They measured a distance of 88 yards on a straight road and watched to see how long it took a car to travel that far. They knew that if a car took less than six seconds, it was traveling faster than the speed limit of 30 miles an hour.

When the policemen were ready, they hid behind a hedge and started to time passing vehicles. During their first half an hour, they caught five drivers. The policemen wrote down the number of each car and the name and address of the driver. But for the next half an hour the policemen did not see anybody driving too fast. They thought that this was very strange. One of them drove a quarter of a mile along the road and saw two students sitting on the grass. They were homing up a sheet of cardboard so that motorists could see it. On the notice one of the students had written: "Danger. Speed Trap."

The policemen took the notice away and wrote down the names of the students. Later on they were each fined £5 for trying to stop the policemen from catching motorists who were breaking the law.

(33)

A.It would be normal if the car took just four seconds.

B.It would be normal if the car took six seconds.

C.It would be normal if the car took less than three seconds.

D.It would be normal if the car took less than six minutes.

听力原文: The year is 2501, and the Earth is desperately short of fuel. All Earth's coal, oil and wood have been used up long ago, and scientists have been sent to the ends of the universe in search of alternative forms of energy.

A rich and powerful civilization has been discovered on the planet Jupiter, and Earth is supplied with fuel by constant supply fleets from that planet, but the price is very high. Unless it discovers an alternative source of energy soon, civilization on Earth will fail, and its inhabitants will have to move to other planets where they will be little more than slaves. Then Jupiter will take possession of Earth-- the most beautiful, most desirable planet in the universe.

Human scientists have been sure for a long time that Jupiter possesses a method of creating constant energy and now ten explorers on a secret mission from Earth have discovered the secret--a kind of heavy, green dust which will change salt water to high grade petroleum. This dust covers a large part of Jupiter's surface, and just a few pounds of it could solve the world's energy crisis since it would reproduce itself continuously in Earth's atmosphere.

(23)

A.Explorers.

B.Doctors.

C.Teachers.

D.Coal-miners.

听力原文:Nearly 400 years ago a young man traveled up to London. The young man had come on

听力原文: Nearly 400 years ago a young man traveled up to London. The young man had come on foot from Stradfurd-on-Avon, a small town on the Avon. He was poor, but he had confidence in his future, the future of a great actor. His name was William Shakespeare.

He had not been in London very long before he noticed that play-goers all went to the theatre on horseback. "Here is an opportunity!" he thought," There must be someone to take care of the horses when people are watching a play." So he began to do the job and he did it so well that people all liked him very much.

Soon the actors found the young man a very premising actor and he was given an opportunity to play a part on the stage. From that time on, his name became known. But he was not content with the life of an actor. He took great interest in play-writing. The plays he wrote, popular in England of his own time and up to the present day, have shown him to be one of the greatest writers the world has ever produced. He is among those who are loved by the people in all time and in all lands.

(30)

A.Because he wanted to be a great actor.

B.Because he wanted to be a playwright.

C.Because he was too poor to live on.

D.Because he wanted to take care of horses.

听力原文:Why don't birds got lost on their long migratory flights? Scientists have puzzled

听力原文: Why don't birds got lost on their long migratory flights? Scientists have puzzled over this question for many years. Now they're beginning to fill in the blanks.

Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly by night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the stars in their long-distance flights.

One such bird—a warbler—had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the make-believe stars caused a change in the direction of his flight.

Scientists think that warblers, when flying in daylight, use the sun for guidance. But the stars are apparently their principal means of navigation. What do they do when the stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines, and rivet courses. But when it's too dark to see these, the warblers circle helplessly, unable to get their bearings.

(33)

A.Birds have to be taught to navigate.

B.A bird that has been caged will not.

C.Some birds cannot fly at night.

D.Some birds seem instinctively to follow the stars when flying at night.

听力原文:In 1863, President Lincoln made a law. This law said that only the United States

听力原文: In 1863, President Lincoln made a law. This law said that only the United States government could print money. The law gave us the kind of money we have today. At that time, people could take their money to banks. At the banks they could get a certain amount of silver in exchange for the money. In 1873, the banks began to give gold for paper money. The idea worked if too many people didn't go to the banks at the same time. Banks didn't always have enough gold. The government stopped this about 60 years ago. We can no longer go to banks to get gold for our money. The government will not exchange anything for paper money.

The value of money we use today is not the same as animals or food. It is not the same as an amount of silver, gold, or copper. The way people used money a long time ago may have been easier than it is to day. They know what it meant. Today the money in our pocket means different things at different times.

(33)

A.In 1853.

B.In 1863.

C.In 1860.

D.In 1873.

听力原文:Ancient man, living in colder climates, is credited with making the first shoes,

听力原文: Ancient man, living in colder climates, is credited with making the first shoes, by adding material to the top of the crude "sandals" his neighbors in warmer climates had invented. He did so out of necessity, to give his feet additional protection from the cold.

Early man, in warmer climates, invented the sandal to protect his feet from sharp rocks, and did so by strapping a mat of woven grass, a strip of animal hide, or a slab of flat wood to his feet with "thongs" he cut out of animal hide. Some even pulled the thongs between the toes and tied them around the ankles to tighten the fit of these crude sandals.

Wealthy ancient Egyptians wore sandals as long as 5,000 years ago, eventually everyone began wearing them, and the Egyptians designed differently. Ancient Greeks invented the boot, by replacing the sandal's thongs with solid leather. Many of these crude shoes have endured and are still worn today. Common examples include the sandals the ancient Greeks and Romans wore, the moccasins American Indians wore, and the clogs people in Holland still wear.

In the Middle Ages, around the time the Crusades began, modem shoes appeared on the scene. The Crusaders, who went on long treks, needed durable, comfortable shoes that people then began making for this purpose.

(23)

A.To give his feet additional protection from the cold.

B.To make the sandals wear-resisting.

C.To match his trousers.

D.To make the sandals look more beautiful.
