25、s. 31 We all know that a magician does nor really depend on “magic“ to perform his tricks,【 C1】 _ on his ability to act at great speed.【 C2】 _ , this does not prevent us from enjoying watching a magician【 C3】 _ rabbits from a hat.【 C4】 _ the greatest magician of all time was Harry Houdini who died i

26、n 1926, Houdini mastered the art of【 C5】 _ . He could free him- self from the tightest knots or the most complicated locks in seconds.【 C6】 _ no one really knows【 C7】 _ he did this, there is no doubt【 C8】 _ he had made a close study of every type of lock ever【 C9】 _ .

The pupils of the animals eyes narrowed and the electroencephalograms showed slow waves characteristic of deep sleep within five to ten minutes. More recently,

35、 Koella deprived cats of serotonin. The animals, again equipped with implanted electrodes, were given PCPA, a drug that blocks the formation of serotonin. They were then placed in small compartments fitted with one-way mirrors and watched round the clock. Normally cats sleep about 15 hours a day; bu

36、t Koellas cats, after receiving PCPA, spent about 30 minutes of each day sleeping. Most of the time, their EEGs showed the brainwave patterns of arousal. Occasionally the cats would curl up as if to go to sleep, but would soon get back on their feet to wander about. The animals showed signs of irrit

37、ability and often meowed complainingly after a few days of sleep deprivation, but had normal reflexes. The effects of the PCPA wore off eight days to two weeks after administration of the drug; the cats returned to their normal sleeping patterns as serotonin levels in their brains rose again. Koella

38、 believes that at least some types of chronic insomnia may be caused by a drop in brain - serotonin levels. The Worcester physiologist is now working on chemical ways to raise the brains serotonin levels and produce, in his words, “a truly physiological sleeping pill.“ Synthetic sleeping pills, such

39、 as barbiturates, bring sleep, but at a price: they depress the central nervous system, reduce heart action and respirationand they can become habit-forming or even addictive. In one promising experiment toward the goal of letting the body “make its own pill,“ Koella has found that administration of

40、 5-hydroxytryptophan, the chemical substance from which the body derives serotonin, will quickly restore a normal sleeping pattern to cats lacking in serotonin. 86 The brain stem is located (Paragraph 2 ) _. （ A） in the hypothalamus （ B） between the brain and the spinal cord （ C） in the transmitter

41、nerve cells （ D） between the hypothalamus and the brain 87 The information in paragraph 5 indicates that PCPA was responsible for _. （ A） a lack of sleep （ B） the cats meowing （ C） normal sleeping patterns （ D） sleeping about 15 hours a day 88 The language used in this article indicates that Dr. Koe

42、lla _. （ A） is positive that serotonin controls sleep （ B） is quite uncertain whether serotonin controls sleep （ C） thinks that serotonin cant be extracted （ D） thinks that serotonin might control sleep 89 A good title for this article would be _. （ A） The Cats Want to Sleep （ B） I Cant Sleep Tonigh

43、t （ C） How to Get Asleep （ D） Some New Sleep Research 89 As the cost of gas and oil for home heating has gone up, many Americans have switched from these fuels to wood for heating their homes. In 1973, approximately 200,000 wood-burning stoves, intended for home use, were sold in the United States;

44、by 1979, this figure had reached one million; and by the end of 1981, there were as many as seven million home-owned wood-burning units in operation in the U. S. In addition to low fuel bills, many people choose these stoves because their initial cost is very low (the prices range from $ 50 kits to

45、$ 5,000 top-of-the-line models) , and because new technology has made wood fires more efficient, cleaner, and, therefore, safer than ever before. One new technological feature of this type is the catalytic(催化 ) combustor which adds about $100 to $ 200 to the cost of the stove, but which causes much

46、more complete combustion(燃烧 ) of the wood and therefore burns up more of the pollutants left by incomplete combustion and produces more heat. A second cost-saving innovation is a device which agitates the wood, increasing the amount of oxygen that reaches the center of the wood pile, and leading to

47、more efficient combustion. The real advantage of this device is that it allows the owner to make use of cheap sources of wood such as dirty wood chips ( an industrial by-product) that have almost no commercial value, cost as little as $ 20 a ton, and burn very inefficiently in furnaces without an ag

48、itator. 90 According to the passage, the number of wood-burning stove sold for home use _. （ A） went up fivefold over a six-year period. （ B） rose to seven million during the seventies. （ C） multiplied thirty-five times between 1973 and the beginning of 1981. （ D） increased by 6,000,000 over an eigh

49、t-year period. 91 Which one of the following is NOT true for the reason why people prefer to buy wood-burning stoves? （ A） The initial cost is very low. （ B） The fuel costs are cheaper. （ C） Wood fires are more efficient, cleaner, and safer than ever before. （ D） The wood-burning stoves are more efficient than gas or oil ones. 92 Which of the following statements is NOT
