33、ead a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived You may choose a paragraph more than once. Each paragraph is marked with a letter.Animals on the MoveA. It looked like a

34、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 sharks skin picked up vibrations of a struggling fish. The shark was immediately transformed int

35、o 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 tore huge chunks of flesh from its victim and swallowed them. S

36、oon the action was over.Moving to SurviveB. 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 terri

37、tories. 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, rockets, and submarines transport humans from deep oceans to as f

38、ar 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 prey has always impressed scientists. But it took a detailed stud

39、y 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 were taken of the sharks movements and analyzed. Studies were als

40、o made of shark skin and muscle.Skin Is the KeyC. 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

41、. 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 pulled tight. When the energy is released, the fibers become relaxed.D.

42、 The Duke 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 relea

43、sed when 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.Source of EnergyE. What causes the fibers to store

44、 so much 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,

45、the pressure 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. The fibers are more relaxed, and the shark is able to bend its body at sharp angles. The animal swims this way when looking aro

46、und 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, enabling 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.Dolphin Has Speed RecordG. Another fast marine animal is the dolphin. This seagoing mammal
