Section A 26 Many workers who worked in the World Trade Center after the September eleventh attacks became sick. They breathed a mix of dust, smoke and chemicals in the ruins of the Twin Towers and a

17、 third building that fell. Some went clays without good protection for their【 C1】 _. Five years later, many of the thousands who worked at Ground Zero in the early days after the attacks still have health problems. Doctors at Mount Sinai Medical Center in New York City have【 C2】 _the results of the

18、largest study of these workers. The study【 C3】 _high rates of breathing problems in members of the building traders, firefighters, police officers and other workers. Almost seventy percent of the workers in the study had a new or worsened breathing problem. These problems developed during or after t

19、heir time working in the mountain of【 C4】 _. About sixty percent still had breathing problems at the time of their【 C5】 _. The researchers say they decided to study the effects on breathing first because other disorders might be slower to appear. Mount Sinai says it tested almost twelve thousand peo

24、aws“ 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 sharks skin picked up vibrations of a struggling fish. The shark was immediately transformed into a deadly, e

25、fficient 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 tore huge chunks of flesh from its victim and swallowed them. Soon the actio

26、n 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 locomotion to escape enemies, find a mate, and explore new territories. The

27、 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, rockets, and submarines transport humans from deep oceans to as far away as

28、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 prey has always impressed scientists. But it took a detailed study by Duke U

29、niversity 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 were taken of the sharks movements and analyzed. Studies were also made of s

30、hark skin and muscle. C) Skin Is the Key The biologists discovered that the skin of the shark is the key to the animals high efficiency in swimming through the water. The skin contains many fibers that crisscross like the inside of a belted radial tire. The fibers are called collagen fibers. These f

31、ibers 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 pulled tight. When the energy is released, the fibers become relaxed. D) The Duk

32、e University biologists have found that the greatest stretching occurs where the shark bends its body while swimming. During the bodys back and forth motion, fibers along the outside part of the bending body stretch greatly. Much potential energy is stored in the fibers. This energy is released when

33、 the sharks body snaps back the other way. As energy is alternately stored and released on both sides of the animals body, the tail whips strongly back and forth. This whip-like action propels the animal through the water like a living bullet. E) Source of Energy What causes the fibers to store so m

34、uch energy? In finding the answer the Duke University scientists learned that the sharks similarity to a belted radial tire doesnt stop with the skin. Just as a radial tire is inflated by pressure, so, too, is the area just under the sharks collagen “radials“. Instead of air pressure, however, the p

35、ressure in the shark may be 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 angles. The animal swims this way when looking around for food or just swimming. Ho

36、wever, 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, enabling much energy to be stored. This energy is then transferred to the tail, and the s

37、hark 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 studying the dolphin have discovered that, like the shark, the animals efficient l

38、ocomotion can be traced to its skin. A dolphins 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, the water flows smoothly past the body. This smooth flow is known as laminar flow. Ho

39、wever, 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 of the water. The waves, in effect, become tucked into the skins folds. This allows

40、 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 Animals Less Efficient Not all animals move as efficiently as sharks and dolphins. Perhaps

41、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 crawling over it that a mouse traveling the same distance uses only one twelfth as much ener

42、gy. J) Scientists say that because of the slugs 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 ever been faced with this kind of problem? 37 A dolph

43、ins skin enables it to pass through with little resistance to the water flowing over it. 38 A shark finds its prey by feeling the vibrations of a struggling prey. 39 According to the scientists, when bending its body in swimming, the shark stretches its collagen fibers to the greatest extent. 40 Ani

44、mals are restricted to small areas for obtaining food and finding proper living conditions. 41 Automobiles, rockets, and submarines exemplify that human inventions enable us to travel in almost any kind of environment. 42 Consuming the equal amount of energy as a slug does, a mouse can travel 12 tim

45、es as long as a slug. 43 Dolphin wouldnt be bothered by turbulent water at rapid speeds like other animals. 44 One of the main reasons why sharks are such effective predators is their skin. 45 Sharks are a notable example of fish that depend on locomotion to survive. 46 The area just under the shark

46、s collagen fibers is similar to a belted radial tire because it is also inflated by pressure. Section C 46 Most of us are taught to pay attention to what is saidthe words. Words do provide us with some information, but meanings are derived from so many other sources that it would hinder our effectiv

47、eness as a partner to a relationship to rely too heavily on words alone. Words are used to describe only a small part of the many ideas we associate with any given message. Sometimes we can gain insight into some of those associations if we listen for more than words. We dont always say what we mean

48、 or mean what we say. Sometimes our words dont mean anything except “Im letting off some steam. I dont really want you to pay close attention to what Im saying. Just pay attention to what Im feeling. “Mostly we mean several things at once. A person wanting to purchase a house says to the current own

49、er, “This step has to be fixed before Ill buy.“ The owner says, “Its been like that for years.“ Actually, the step hasnt been like that for years, but the unspoken message is; “I dont want to fix it. We put up with it. Why cant you?“ The search for a more expansive view of meaning can be developed of examining a message in terms of who said it, when it occurred, the related conditions or situations, and how it was said. When a message occurs can also reveal associated meaning. Let us assume t
