22、mself, and never across the face of our planet has outcome been more in doubt. Malnutrition caused much suffering to an estimated 400 million to 1.5 billion of the worlds poor. Even in the wealthy US poverty means undernourishment for an estimated ten to twenty million. Hardest hit are children, who

23、se growing bodies demand two and a half times more protein, pound for pound, than those of adults. Nutrition experts estimate that 70 percent of the children in low-income countries are affected.Badly shaped bodies tell the tragic story of malnutrition. Medical science identifies two major types of

24、malnutrition which usually occur in combination. The first, kwashiorkor (恶性营养不良), is typified by the bloated look. The opposite of what we associate with starvation. Accumulated fluids pushing against wasted muscles account for the plumpness of hands, feet, belly, and face. Lean shoulders reveal str

25、iking thinness. Caused by an acute lack of protein kwashiorkor can bring brain damage, anemia, diarrhea, irritability, apathy, and loss of appetite.On the other hand, stick limbs, a bloated belly, wide eyes, and the stretched skin face of an old person mark victims of marasmus, a word taken from the

26、 Greek “to waste away“. Lacking calories as well as protein, sufferers may weigh only half as much as normal. With fat gone, the skin hangs in wrinkles or draws tight over bones. With marasmus comes anemia, diarrhea, dehydration, and a very hungry appetite. Children, whose growing bodies require lar

27、ge amounts of protein, have to suffer in greatest numbers, but perhaps only three percent of all child victims suffer the extreme stages described.Scientists are doing best to develop new weapons against malnutrition and starvation. But two thirds of the human population of 3.9 billion live in the p

28、oorest countries which also have the highest birth rates. Thus, of the 74 million people added to the population each year, four out of five will be born in a country unable to supply its peoples nutritional needs.（分数：10.00）(1).Malnutrition has caused much suffering to millions of people all over th

29、e world for a long time_.（分数：2.00）A.but the problem is not as serious now as beforeB.and the problem is as serious now as at any time beforeC.but the future looks quite promisingD.but the problem is likely to become less serious(2).According to the author, children_.（分数：2.00）A.suffer more than adult

30、s because they eat less foodB.suffer less than adults because they are physically smallerC.are affected more than adults since their food contains less proteinD.are affected more than adults simply because they need more protein(3).Children suffering from “kwashiorkor“ will look_.（分数：2.00）A.plump in

31、 feet and hands, as well as faces and bodies, but their shoulders are very thinB.bloated all over their bodiesC.plump in feet and hands, as well as faces and bodies, especially in shouldersD.swollen, an appearance that we associate with starvation(4).Children suffering from “marasmus“ will_.（分数：2.00

32、）A.look like old men and lose their appetiteB.have extremely thin arms and legs, but big bellies, and they will easily get angry at small things, and they may suffer from brain damageC.have extremely thin arms and legs, but big belliesD.have long, thin faces like old men, and feel hungry all the tim

34、nderdeveloped countriesBText 2/BFor years there have been endless articles stating that scientists are on the verge of achieving artificial intelligence, that it is just around the corner. The truth is that it may be just around the corner, but they havent yet found the right clock.Artificial intell

35、igence aims to build machines that can think. One immediate problem is to define thought, which is harder than you might think. The specialists in the field of artificial intelligence complain, with some justification, that anything that their machines do is dismissed as not being thought. For examp

36、le, computers can now play very, very good chess. They cant beat the greatest players in the world, but they can beat just about anybody else. If a human being played chess at this level, he or she would certainly be considered smart. Why not a machine? The answer is that the machine doesnt do anyth

37、ing clever in playing chess. It uses its blinding speed to do a brute-force search of all possible moves for several moves ahead, evaluates the outcomes and picks the best. Humans dont play chess that way. They see patterns, which computers dont.This wooden approach to thought characterizes machine

38、intelligence. Computers have no judgment, no flexibility, no common sense. So-called expert systems, one of the hottest areas in artificial intelligence, aim to mimic the reasoning processes of human experts in a limited field, such as medical diagnosis or weather forecasting. There may be limited c

39、ommercial applications for this sort of thing, but there is no way to make a machine think about anything under the sun, which a teenager can do. The hallmark of artificial intelligence to date is that if a problem is severely restricted, a machine can achieve limited success. But when the problem i

40、s expanded to a realistic one, computers fall flat on their display screens. For example, machines can understand a few words spoken individually by a speaker that they have been trained to hear. They cannot understand continuous speech using an unlimited vocabulary spoken by just any speaker.（分数：10

42、chieved artificial intelligence(2).We learn from the second paragraph that_.（分数：2.00）A.the writer thinks that the specialists complaints have some reasonsB.anything that the computer does can be regarded as thoughtC.it is not very difficult to define thoughtD.computers play chess in exactly the same

46、French national team.Henry was born and brought up in the tough neighborhood of Les Ulis, Essonnea suburb of Pariswhere he played for an array of local sides as a youngster and showed great promise as a goal-scorer. He was spotted by AS Monaco in 1990 and signed instantly, making his professional de

47、but in 1994. Good form led to an international call-up in 1998, after which he signed for the Italian defending champions Juventus. He had a disappointing season playing on the wing, before joining Arsenal (兵工厂) for 10.5 million in 1999.It was at Arsenal that Henry made his name as a world-class foo

48、tballer. Despite initially struggling in the Premiership, he emerged as Arsenals top goal-scorer for almost every season of his tenure there. Under long-time mentor and coach Arsne Wenger, Henry became a prolific striker and Arsenals all-time leading scorer with 226 goals in all competitions.
