Every country has its heroes. The heroes are the people the nation and especially the young people admire. If you get a list of the heroes of a nation, it will tell you the potential（潜势）of that nation.
If today in America, you ask the high school students to list their heroes, their choice would probably fall into three groups. The first group of heroes would be the rock stars —the people connected with rock music. There is no doubt that such people do have talent but one wonders if one should hold up rock stars as a model (推举…为榜样). The rock stars too often are involved with drugs and their personal life is not all that good. The rock stars are rich and wear the latest fashion styles. However, one should seek more in a hero than such things as money and good clothes.
A second type of hero for the American youth is the sports star. Again you have a person who has a great ability in one area — SPORTS. However, too often the personal life of the sports star is a bit of a mess. Too frequently drugs and drinking are a part of life of the sports star.
A third type of hero is the TV or movie star. This person may have lots of acting talent and is quite handsome. However, the personal life of too many actors is quite sad and they should not be held up as a model for young people.
Today, the rock star, the athlete and the actor all have become the models of the youth in America. Really, do you hear a young person say that his hero is a doctor, a teacher, or a scientist? These people are not rich and do not wear fashionable clothes. However, they are talented people who work hard to make the world a better place for everyone.
What is really sad is that the young try to imitate their heroes. They like to wear the same clothes and follow their styles. If the heroes of today for the American youngsters are only rock stars, athletes and actors, the future does not look too bright.
1. The hero discussed in this article means a person ______.
A. who has done something brave B. who plays an important role in a play

A. a university professor B. a popular singer C. a football player D. a film actress
4. According to the writer, people should hold up as their model those______.
A. who are rich and wear the latest fashion clothes B. whose personal life is good
C. who can express people’s feelings D. who work in the interests (利益) of the people
5. What is the writer’s attitude towards American youth’s admiration for their heroes?
A. He is understanding. B. He is critical. C. He is angry. D. He is uninterested.

Have you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That’s nothing more than a fiction.
But could we really clone endangered animals?
To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope (邦戈羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda. Next, could we really clone extinct animals?
In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother.
In reality? Probably not. On the one hand, it’s not likely that extinct animals’ DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as a surrogate mother, definitely not a monkey. But what about an extinct animals as unique as the panda? What species could possibly serve as a surrogate mother?
Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today’s world. Not only do most extinct animals have no habitat to love in, but the other plants and animals they depended on for food may also be gone as well.
1. It can be learned from the text that ________.
A. scientists have cloned the African bongo antelope
B. both the cheetah and the giant panda live in Asia
C. the gaur lives in Asia and is endangered
D. the gaur is an extinct species
2. The underlined words “a surrogate mother” probably refer to a female who -----
A. contributes its eggs to another femaleB. gives birth to a baby for another female
C. gives birth to a baby of its own D. cannot give birth to a baby
3. The difficulty in cloning an extinct species is the lack of ______.
A. both the well-preserved DNA and plants to live on
B. both the habitat to live in and the well-preserved DNA
C. both habitat to live in and plants to live on
D. both the well-preserved DNA and a surrogate mother
4. In the author’s opinion, it is possible that ______.
A. some extinct species may be cloned, but not survive
B. extinct species may be cloned and easily survive
C. a gaur can have a monkey as a surrogate mother
D. all the extinct species may be cloned
5．Today , have scientists cloned dinosaus?
A .Yes B .No C .A lot D.Only one.

The Pathfinder
When we found him, he was a sorry sight. His clothes were torn, his hands bleeding. Before we reached him, we saw him fall. He lay a moment. Then he pulled himself to his feet, walked unsteadily a few yards through the woods and fell again.
After we got him out, we went back to find the gun that he had thrown down. His tracks showed that for two days he had circled in the forest, within 200 yards of the road. His senses were so dulled by fear and tiredness that he did not hear the cars going by or see the lights at night.
We found him just in time.
This man, like others before him, had simply been frightened when he knew he was lost. What had been a near disaster might have turned out as only a pleasant walk, had he made a few preparations before he stepped from the highway or off a known path.
Whatever sense of direction that a man may have, it’s still largely a question of observation. A skilled woodsman always keeps an eye on his surroundings. He notes that the shape of a mountain, the direction water flows through a swamp, and the way a tree leans across a path. With these in mind, he may be turned around many times, but he is seldom lost.
There are exceptions, of course, and once in a while a man does come across some strange problem that puts him into the “lost” situation. A rainstorm or sudden blizzard may catch him without a compass（指南针）in his pocket. Darkness may find him in a rough area, where travel is dangerous without a light.
When this happens, the normal first reaction（反应）is the fear of being laughed at as a result of his poor knowledge in the woods. He may also be concerned about the inconvenience that he will cause his friends when he doesn’t show up. This false pride may lead him to keep on the move in a false effort to find his way against all difficulties.
The person who thinks ahead is seldom in great danger. He’ll be safe if he observes carefully, thinks ahead, and remains calm.

A German company was concerned about talks in Moscow trying to sell some 100 million dollars worth of equipment to a Russian State company. Talks went smoothly but differences remained. So Martin Bayer himself, the CEO of the German Company, decided to come to Moscow to head the talks. Besides caring about his business, the CEO wanted to go to Russia to hunt bears.
Martin Bayer was one of the greatest hunters of our time (and the Russians knew about it). He went to the Sahara more than hundred times and hunted lions, crocodiles; he hunted polar bears in the North Pole and tigers in the rain forests of India. But he had never hunted Russian bears.
So the Russians decided to organize a bear hunt for Mr. Bayer to sweeten the talks. This wasn't a simple task. Some people in the west still believe that bears may be found and seen everywhere in Russian cities just like squirrels may be seen in our back yards. This is not true. The closest place one may find bears in the wild is maybe 2,500 miles away from Moscow. However, a solution was quickly found. The Russian businessmen went to Moscow Circus（马戏团）and for $2,000 bought a very old bear. This bear used to amuse and amaze audiences in many countries for 30 years, but got and looked too old, and was retired.
“Be careful, the Russian bears are very dangerous, and frightening,” they told to Mr. Bayer. “If compared to the Russian bears, your African lions are nothing more than harmless cats.” The bear was brought to a forest 50 miles from Moscow and was left there. Mr. Bayer was told that bears were plentiful in that forest and that many cattle and even people had been eaten in the surrounding villages.
Meanwhile, an 18-year old female drove through the forest on a motorcycle and suddenly saw a bear (no bears had been seen in those places for 200 years). She was frightened, fell, left her helmet and her motorcycle and ran away.
Mr. Bayer was excited and ready to hunt. This could become the most successful part of his extraordinary hunting experience. The next moment Mr. Bayer saw a bear in a helmet driving on a motorcycle through the forest in front of him. The bear had a happy expression on his face, as he was doing something he had been doing in the circus for 30 years: circling on a motorcycle!
Mr. Bayer lives in a private mental institution near Hamburg happily ever after. The equipment was never sold to Russia. It was sold to Iraq instead.
1. Why did the Russians invite Mr. Bayer to hunt bears?
A. Russian bears are famous for their cruelty.
B. They managed to find a bear for hunting.
C. They expected the trade to be successful.
D. There was a bear in Moscow Circus.
2. Why did the Russians say “Be careful, the Russian bears are very dangerous, and frightening”?
A. To tell Mr. Bayer that many people had been killed by bears.
B. To make Mr. Bayer feel the hunting really challenging.
C. To warn Mr. Bayer to mind his safety while hunting.
D. To tell Mr. Bayer that the bear is really dangerous.
3. We can infer from the last paragraph that __________.
A. Mr. Bayer has gone ma
B. the bear injured him badly
C. he has worked in a mental institution since then
D. the trade has gone smoothly between Russian and Iraq
4. Which would be the best title of the passage?
A. Mr. Bayer, a Brave Hunter B. Russian Bears, Dangerous Animals
C. Don’t Hunt in Russia D. Don’t Deal with the Russians

Science is a major topic in our culture. Since it touches almost every field of our life, educated people need at least some knowledge with its structure and operation. They should also have an understanding of the scientific subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific ideas is easier to obtain if one knows something about the things that excite and discourage the scientist.
This book is written for the person whose knowledge with science is not complete; for the person who has been presented with science as a musty（发霉的）storehouse of dried facts; for the person who sees the chief objective of science as the production of tricks; and for the person who views the scientists as some sort of magician. The book can be used to add to a course in any science, to come with any course that attempts to give an understanding of the modern world, or simply to provide a better understanding of science. We hope this book will lead readers to a broader view on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an idea and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. Besides, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies（哲学）that are deep in our culture.
We have tried to present in this book a correct and up-to-date picture of the scientific world and the people who populate it. That population has in recent years come to include more and more women. This increasing role of women is not just the only event but, rather, part of the trend obvious in all parts of society, as more women enter traditionally male-controlled fields and make influential contributions.
We have also tried to make the book entertaining as well as informative. Our method is usually informal. We feel, as do many other scientists, that we shouldn’t take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a cruel and unpleasant way to earn a living.
