　　 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.

　　 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.
