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 roaring 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 it is often difficult to calculate the number of such large impacts on Earth because erosion and vegetation make it difficult to spot them. In recent 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.

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: You may remember that a few weeks ago, we discussed the question of what photography is. Is it art, or is it a method of reproducing images? Do photographs belong in museums or just in our homes? Today I want to talk about a person who tried to make his professional life an answer to such questions.

Alfred Stieglitz went from the United States to Germany to study engineering. While he was there, he became interested in photography and began to experiment with his camera. He took pictures under conditions that most photographers considered too difficult—he took them at night, in the rain, and of people and objects reflected in windows. When he returned to the United States, he continued these revolutionary efforts. Stieglitz was the first person to photograph skyscrapers, clouds, and views from an airplane.

What Stieglitz was trying to do in these photographs was what he tried to do throughout his life: make photography an art. He felt that photography could be just as good a form. of self expression as painting or drawing. For Stieglitz, his camera was his brush. While many photographers of the late 1800' s and early 1900' s thought of their work as a reproduction of identical images, Stieglitz saw his as a creative art form. He understood the power of the camera to capture the moment. In fact, he never retouched his prints or made copies of them. If he were in this classroom today, r m sure he' d say, "Well, painters don' t normally make extra copies of their paintings, do they?"

(30)

A.How to analyze photographic techniques.

B.How to define photography.

C.How Alfred Stieglitz contributed to the history of photography.

D.Whether photography is superior to other art forms.

听力原文: Throughout history, sports have played an important role in society. Not only have they been a source of entertainment for both the player and the spectator, but they have served as a pleasurable way of ensuring the physical fitness of citizens of all ages.

The popularity of different sports varies from one country to another. Factors such as tradition, climate and cost obviously influence the types of sports that are played by both amateur and professional athletes in various countries. Contrary to winter sports like ice hockey and downhill skiing, table tennis, badminton and fishing, for example, do not require expensive equipment or expensive sports facilities.

Television has increased the popularity of sports like football, basketball, tennis and golf. Millions of men and women all over the world watch live broadcasts of the Olympic Games and the World Cup, for example. Star athletes become the topic of conversation, and often serve as models of courage and determination. The re cord-breaking accomplishments of many athletes are inspirational examples of men and women approaching the limits of human endeavor. Although their performances have been enhanced by major improvements in equipment and training, these sports stars usually deserve the glory and celebrity status they receive.

However, many educators feel that too much emphasis has been placed on the development of professional athletes. Physical education teachers often stress the importance of competitive sports for all young people, not just a select few of the excellent ones. They point out that sports help channel energy in a positive way and contribute to the development of determination and self-discipline. All boys and girls, irrespective of their athletic abilities, should be able to benefit from the joys and disappointments of competitive sports.

(33)

A.Badminton.

B.Fishing.

C.Table tennis.

D.Ice hockey.

Throughout history people have been put to death for various forms of wrongdoing. The deat
h penalty is the most controversial penal practice in the modem world. Other harsh, physical forms of criminal punishment—referred to as corporal punishment (体罚) —have generally been eliminated in modem times. In the majority of countries, contemporary methods of punishment—such as imprisonment or fines—have abandoned infliction (施加) of physical pain. Although imprisonment and fines are universally recognized as necessary to the control of crime, the nations of the world are split on the issue of capital punishment. About 90 nations have abolished the death penalty and an almost equal number of nations retain it.

The trend in most industrialized nations has been to first stop executing prisoners and then to substitute long terms of imprisonment for death as the most severe of all criminal penalties. The United States is an important exception. The federal government and a majority of U.S. states provide for the death penalty, and on average 75 executions occur each year throughout the United States.

Since ancient times most governments have punished crimes by death as a routine part of the administration of criminal law. However, in the nfid-18th century, social critics began to criticize government practices they considered unjust, including capital punishment. The debate over whether governments should utilize the death penalty continues today.

Critics of capital punishment argue that it is cruel and insulting; while supporters assert that it is a uniquely effective punishment that prevents crime. However, advocates and opponents of the death penalty dispute the proper interpretation of statistical analyses of its preventing effect. Opponents of capital punishment see the death penalty as a human fights issue involving the limits of governmental power. In contrast, the advocates tend to regard capital punishment as an issue of criminal justice policy. Because of these alternative viewpoints, there will be further debate not only about what is the right answer on capital punishment, but about what type of question is being asked when the death penalty becomes a public issue.

According to the first paragraph, corporal punishment ______.

A.is a controversial penal practice now

B.is mere welcome than death penalty in most countries

C.is more effective than imprisonment and fines

D.is all history in most countries

Olympic TorchesEvery two years, people around the world wait in anticipation as a torch-be

Olympic Torches

Every two years, people around the world wait in anticipation as a torch-beating runner enters the Olympic arena and lights the cauldron(主火炬). The symbolic lighting of the Olympic flame marks the beginning of another historic Olympic Games.

The opening ceremony is the end of a long journey for the Olympic torah. By the time it arrives in the stadium, it has traveled thousands of miles. It may have crossed oceans and deserts and traversed mountains. It may have been carried on planes, trains, bicycles, boats, and even dog sleds. And it will have passed through the hands of thousands of different people around the globe. This article chronicles the history of the Olympic torch, reveals how it is designed to stay lit through even the harshest weather conditions, and follows its path from Olympia, Greece, to the Olympic Games.

History of the Torch

Fire is always held great power for humans. It cooks our food, keeps us warm, and lights our way through the dark.

The ancient Greeks revered the power and fire. In Greek mythology, the god Prometheus stole fire from Zeus and gave it to humans. To celebrate the passing of fire from Prometheus to man, the Greeks would hold relay races. Athletes would pass a lit torch to one another until the winner reached the finish line.

The Greeks held their first Olympic Games in 776 B.C. The Games, held every four years at Olympia, honored Zeus and other Greek gods. The Olympics also marked the beginning of a period of peace for the often warring Greeks. At the start of the Games, runners called "heralds of peace" would travel throughout Greece, declaring a "sacred truce(休战) "to all wars between rival city-states. The truce would remain in place for the duration of the games, so that spectators could safely travel to the Olympics.

A constantly burning flame was a regular fixture throughout Greece. It usually graced the alters(祭坛) of the Greek gods. In Olympia, there was an altar dedicated to Hera, goddess of birth and marriage. At the start of the Olympic Games, the Greeks would ignite a cauldron of flames upon Hera's altar. They lit the flame using a hollow disc or mirror called a skaphia, which, much like the modern oval mirror, focused the sun's rays into a single point to light the flame. The flame would burn throughout the Games as a sign of purity, reason, and peace.

The Greeks stopped holding their Olympic Games after about a thousand years, and the torch, relays and lighting of the flame also stopped. The Olympic Games did not reemerge until 1896, when the first modern Games were held in Athens. The torch relay took a bit longer to reemerge.

The Birth of the Modern Torch Relay

The flame was reintroduced to the Olympics at the 1928 Amsterdam Games. A cauldron was lit, but there was no torch relay.

The first Olympic torch relay was at the 1936 Berlin Summer Games. Carl Diem, a German history professor and Secretary General of the Organizing Committee of the Games inn, educed the relay as a way of reconnecting the modern Olympics with the Games' historical roots. The flame was lit in Olympia, Greece, just as it had been centuries before. Then it was carried to Berlin, Germany, for the start of the Olympics.

The torch relay was not introduced to the Winter Olympics until the 1952 Games. It was lit that year not in Olympia, Greece, but in Norway, which was chosen because it was the birthplace of skiing. But since the 1964 Olympics at Innsbruck, Austria, every Olympic Games—Winter and Summer—has begun with a torch-lighting ceremony in Olympia, Greece, followed by a torch relay to the Olympic stadium.

The Lighting of the Olympic Torch

The Olympic torch is lit several months before the start of the actual Games. The flame begins its journey at the site of the original Olympic Games—Olympia, Greece. It is lit,just
