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

听力原文： Not long ago, some of you may have read about the team of mountain climbing scientists 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 precise measurement, using a new method that takes advantage of recent advances in technology; it's called the Glob al 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.

(33)

A．The advantages of traditional surveying methods.

B．Using satellites to communicate with mountain climbers.

C．Obtaining new information about a mountain.

D．Controlling satellites from the top of a mountain.

听力原文：Chess must be one of the oldest games in the world. An Arab traveler in India in

听力原文： Chess must be one of the oldest games in the world. An Arab traveler in India in the year 900 wrote that it was played "long long ago". Chess was probably invented in India, and it has been played everywhere in the world, from Asia to Europe, from America to Africa ever since 1400. The name "chess" is interesting. When one player is attacking the other's king, he says in English "check mate". These words came from the Persian words of "Shan mat", which means "the king is dead". That is when the game is over, and one player has won.

Though such an old game changes very slowly, its present rules haven't always been the same as they used to. For example, at one time the queen could only move one square at a time. Now she is the strongest piece on the board. It would be interesting to know why this has happened.

Chess takes time and thought, but it is a game for all kinds of people. You don't have to be a champion in order to enjoy it. Nor is it always played by two people sitting at the same table. What's more, some of the chess masters are able to play many people at the same time. It is also said that some people play chess by post, which must make chess the slowest game in the world.

(30)

A．He attacks his own king.

B．The other player's king cannot move.

C．The other player says "Shan mat" to him.

D．The other player says "check mate" to him.

听力原文： Long ago, no one in Europe smoked. The tobacco plant was unknown there. It grew in America and Christopher Columbus found it there. Later he returned to Europe and told people about tobacco. He said that the American Indians often smoked it. They threw some tobacco leaves on a fire, then put long tubes in their mouths. The other ends of the tubes were over the fire, so they were able to draw the smoke into their mouth.

About the year 1560 a Frenchman, Jean Nicot, was living in Lisbon, Portugal. He was very interested in all American plants. Some of them were very different from the plants of Europe. He used the leaves of the tobacco plant to cure pain. When a man had a bad pain in a leg or an arm, Nicot put tobacco leaves on the painful place and tried to cure the pain in that way. We say now that tobacco contains nicotine. The word nicotine comes from this man's name.

Sir Walter Raleigh was a famous man in the days of Queen Elizabeth the First. He traveled widely and learnt to smoke. Then he returned to England, but he didn't stop smoking. He used to smoke two pipes every day secretly in his room. When anyone came in, he quickly hid his pipe. A man came in and found clouds of smoke in the room. More smoke was coming from Raleigh's mouth, so the man got some water and threw it over Raleigh. He believed that Raleigh was burning. He ran out of the house and told everybody about it. After this, smoking was not a secret.

(33)

A．In Asia.

B．In Europe.

C．In America.

D．In Latin America.

听力原文： The great advance in rocket theory 40 years ago showed that liquid-fuel rackets were far superior in every respect to the skyrocket with its weak solid fuel, the only kind of rocket then known. However, during the last decade, large, solid-fuel rockets with solid fuels a bout as powerful as powerful fuels have made their appearance, and it is a favorite layman's question to inquire which one is "better". The question is meaningless; one might as well as ask whether a gasoline or a diesel engine is "better", it all depends on the purpose. A liquid-fuel rocket is complicated, but has the advantage that it can be controlled beautifully. The bunting of the rocket engine can be stopped completely; it can be reignited when desired. A solid-fuel rocket, tin the other hand, is rather simple in construction, though hard to build when a really large size is desired. But once you have a solid-fuel rocket, it is ready for action at a very short notice. A liquid fuel rocket has to be fueled flint and Carl not be held in readiness in very long slier it has been fueled. However, once a solid-fuel rocket has been ignited, it will keep burning. It can't be stopped and reignited whenever desired. Because a solid fuel rocket can be kept ready for a long time, most missiles employ solid fuels, but manned space flight needs the line adjustments that can only be pro vided by liquid-fuel rocket. It may be added that a liquid-fuel rocket is an expensive device; a large solid-fund rocket is, by comparison cheap.

A．Neither of the two types of rockets is very economical.

B．The liquid-fuel rocket is best.

C．Each type of rocket has certain advantages.

D．The solid-fuel rocket is best.

听力原文： The great advance in rocket theory 40 years ago showed that liquid-fuel rockets were far superior in every respect to the skyrocket with its weak solid fuel, the only kind of rocket then known. However, during the last decade, large solid-fuel rockets with solid fuels about as powerful as liquid fuels have made their appearance, and it is a favorite layman's question to inquire which one is "better". The question is meaningless; one might as well as ask whether a gasoline or a diesel engine is "better". It all depends on the purpose. A liquid-fuel rocket is complicated, but has the advantage that it can be controlled beautifully. The burning of the rocket engine can be stopped completely; it can be reignited when desired. A solid-fuel rocket, on the other hand, is rather simple in construction, though hard to build when a really large size is desired. But once you have a solid-fuel rocket, it is ready for action at a very short notice. A liquid-fuel rocket has to be fueled first and can not be held in readiness for very long after it has been fueled. However, once a solid-fuel rocket has been ignited, it will keep burning. It can't be stopped and reignited whenever desired. Because a solid-fuel rocket can be kept ready for a long time, most military missiles employ solid fuels, but manned space flight needs the fine adjustments that can only be provided by liquid-fuel rocket. It may be added that a liquid-fuel rocket is an expensive device; a large solid-fuel rocket is, by comparison, cheap.

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.

听力原文： What will man be like in the future--in 5,000 or even 50,000 years from now.'？ We can only make a guess, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity. As time goes on, however, we shall have to use our brains more and more--and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man's eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modem life.

(30)

A．Future man's life style.

B．Future man's thoughts.

C．Future man's appearance.

D．Future man's education.

听力原文：M: So, Rebecca, what did you do for spring break？

W: I went to southern California. I was in Los Angeles and San Diego. Oh, and I stopped in San Juan Capistrano. That's south of Los Angeles and north of San Diego. I happened to be there just about the time the swallows returned.

M: Oh, I've heard about that they always return on the same day, don't they？

W: Yes, except for one year, a long time ago, they were delayed for a day by a storm at sea.
