And, of course, our ability to 2 this high-tech communications equipment is greatly 3 by foreign language skill

20、s. Deeply 4 this new technology is a breed of modern business people who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support 5 business efforts. Overseas assignments are becoming increasingly important to advancement within

21、executive ranks. The executive stationed in another country no longer needs to fear being “out of sight and out of mind“. He or she can be sure that the overseas effort is central to the company“s plan for success, and that promotions often follow or 6 an assignment abroad. If an employee can succee

22、d in a difficult assignment overseas, superiors will have greater confidence in his or her ability to cope back in the United States where cross-cultural and foreign language issues are becoming more and more 7 . Thanks to a variety of 8 inexpensive communications devices with business applications,

23、 even small businesses in the United States are able to get into international markets. English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn“t generally required to get a job in business, but havin

25、arity are not what they used to be. We suddenly can“t remember where we put the keys just a moment ago, or an old acquaintance“s name, or the name of an old band we used to love. As the brain fades, we refer to these 2 as “senior moments“. While seemingly 3 , this loss of mental focus can 4 have a d

26、etrimental impact on our professional, social, and personal well-being. Neuroscientists are increasingly showing that there“s actually a lot that can be done. It turns that the brain needs exercise in much the same way our muscles do, and the right mental workouts can significantly improve our basic

27、 cognitive 5 . Thinking is essentially a process of making neural connections in the brain. To a certain extent, our ability to excel in making the neural connections that drive intelligence is 6 . However, because these connections are made through effort and practice, scientists believe that intel

28、ligence can expand according to mental effort. Now, a new San Francisco Web-based company has taken it a step further and developed the first “brain training program“ 7 to actually help people improve and regain their mental sharpness. It is called Lumosity. Lumosity, is far more than an online plac

Also, the program keeps track of your progress and provides 9 feedback on your performance and improvement. Most important

31、ion B(总题数：1，分数：71.00)Animals on the MoveA. It looked like a scene from “Jaws“ but without the dramatic music. A huge shark was slowly swimming through the water, its tail swinging back and forth like the pendulum of a clock. Suddenly sensitive nerve ending in the shark“s skin picked up vibrations of

32、 a struggling fish. The shark was immediately transformed into a deadly, efficient machine of death. With muscles taut, the shark knifed through the water at a rapid speed. In a flash the shark caught its victim, a large fish, in its powerful jaws. Then, jerking its head back and forth, the shark to

33、re huge chunks of flesh from its victim and swallowed them. Soon the action was over. B. Moving to Survive In pursuing its prey, the shark demonstrated in a dramatic way the important role of movement, or locomotion, in animals. Like the shark, most animals use movement to find food. They also use l

34、ocomotion to escape enemies, find a mate, and explore new territories. The methods of locomotion include crawling, hopping, slithering, flying, swimming, or walking. Humans have the added advantage of using their various inventions to move about in just about any kind of environment. Automobiles, ro

35、ckets, and submarines transport humans from deep oceans to as far away as the moon. However, for other animals movement came about naturally through millions of years of evolution. One of the most successful examples of animal locomotion is that of the shark. Its ability to quickly zero in on its pr

36、ey has always impressed scientists. But it took a detailed study by Duke University marine biologists S. A. Wainwright, F. Vosburgh, and J. H. Hebrank to find out how the sharks did it. In their study the scientists observed sharks swimming in a tank at Marine land in Saint Augustine, Fla. Movies we

37、re taken of the sharks“ movements and analyzed. Studies were also made of shark skin and muscle. C. Skin Is the Key The biologists discovered that the skin of the shark is the key to the animal“s high efficiency in swimming through the water. The skin contains many fibers that crisscross like the in

38、side of a belted radial tire. The fibers are called collagen fibers. These fibers can either store or release large amounts of energy depending on whether the fibers are relaxed or taut. When the fibers are stretched, energy is stored in them the way energy is stored in the string of a bow when pull

39、ed tight. When the energy is released, the fibers become relaxed. D. The Duke University biologists have found that the greatest stretching occurs where the shark bends its body while swimming. During the body“s back and forth motion, fibers along the outside part of the bending body stretch greatly

40、. Much potential energy is stored in the fibers. This energy is released when the shark“s body snaps back the other way. As energy is alternately stored and released on both sides of the animal“s body, the tail whips strongly back and forth. This whip-like action propels the animal through the water

41、 like a living bullet. E. Source of Energy What causes the fibers to store so much energy? In finding the answer the Duke University scientists learned that the shark“s similarity to a belted radial tire doesn“t stop with the skin. Just as a radial tire is inflated by pressure, so, too, is the area

42、just under the shark“s collagen “radials“. Instead of air pressure, however, the pressure in the shark may he due to the force of the blood pressing on the collagen fibers. F. When the shark swims slowly, the pressure on the fibers is relatively low, and the shark is able to bend its body at sharp a

43、ngles. The animal swims this way when looking around for food or just swimming. However, when the shark detects an important food source, some fantastic involuntary changes take place. The pressure inside the animal may increase by 10 times. This pressure change greatly stretches the fibers, enablin

44、g much energy to be stored. This energy is then transferred to the tail, and the shark is off. The rest of the story is predictable. G. Dolphin Has Speed Record Another fast marine animal is the dolphin. This seagoing mammal has been clocked at speeds of 32 kilometers (20 miles) an hour. Biologists

45、studying the dolphin have discovered that, like the shark, the animal“s efficient locomotion can be traced to its skin. A dolphin“s skin is made up in such a way that it offers very little resistance to the water flowing over it. Normally when a fish or other object moves slowly through the water, t

46、he water flows smoothly past the body. This smooth flow is known as laminar flow. However, at faster speeds the water becomes more turbulent along the moving fish. This turbulence muses friction and slows the fish down. H. In a dolphin the skin is so flexible that it bends and yields to the waviness

47、 of the water. The waves, in effect, become tucked into the skin“s folds. This allows the rest of the water to move smoothly by in a laminar flow. Where other animals would be slowed by turbulent water at rapid speeds, the dolphin can race through the water at record breaking speeds. I. Other Animal

48、s Less Efficient Not all animals move as efficiently as sharks and dolphins. Perhaps the greatest loser in locomotion efficiency is the slug. The slug, which looks like a snail without a shell, lays down a slimy trail over which it crawls. It uses so much energy producing the slimy mucus and crawlin

49、g over it that a mouse traveling the same distance uses only one twelfth as much energy. J. Scientists say that because of the slug“s inefficient use of energy, its lifestyle must be restricted. That is, the animals are forced to confine themselves to small areas for obtaining food and finding proper living conditions. Have humans ev
