problem“. To many people, the cause is obvious: they eat too much. But scientific evidence does little to support this idea. Going back to the America of the 1910s,we find that people were thinner than today,yet they ate more food. In those days people worked harder physically, walked more, used machines much less and didnt watch television. Several modern studies, moreo-ver,have shown that fatter people do not eat more on the average than thinner people. In fact, some investigations, such as the study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer people.Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts:The more the men ran, the more body fat they lost.The more they ran, the greater amount of food they ate.Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.21.The physical problem that many adult Americans have is that_.A.they are too slimB.they work too hardC.they are too fatD.they lose too much body fat答案：C22.According to the article,given 500 adult Americans, _ people will have a “weight problem“.A.30B.50C.100D.150答案：D解析：逻辑推理题。答案也在第一段第一句话：30 percent of the adult popula. tion has a“weight problem”(30%的成年人都有体重问题)。因此，如果有 500人的话，那么 150人就会有体重问题。D 为正确答案。23.Is there any scientific evidence to support that eating too much is the cause of a “ weight problem“ ?A.Yes,there is plenty of evidence.B.Of course,there is some evidence to show this is true.C.There is hardly any scientific evidence to support this.D.We don't know because the information is not given.答案：C解析：细节判断题。答案在第一段第三句话：But scientific evidence does little to support this ides(但几乎没有任何科学依据证明这一点)。C 为正确答案。24.In comparison with the adult American population today, the Americans of the 1910s_.A.ate more food and had more physical activitiesB.ate less food but had more activitiesC.ate less food and had less physical exerciseD.had more weight problems答案：A解析：细节判断题。答案在第一段：Going back to the America of the 1910s。we find that people were thinner than today，yet they ate more food.In those days people worked harder physically，walked more，used machines much less and didn't watch television(回顾十八世纪初，那时的人比现在的人瘦，然而却吃得多。那时候，他们工作比现在辛苦，走路比现在多，使用机器比现在少，也不看电视)。因此 A为正确答案。25.Modern scientific researches have reported to us that_.A.fat people eat less food and are less activeB.fat people eat more food than slim people and are more activeC.fat people eat more food than slim people but are less activeD.thin people run less,but have greater increase in food intake答案：A解析：细节判断题。答案在第二段和第三段：Several modern studies have shown that fatter people do not eat more on the average than thinner people;Slim people are more active than fat people。因此胖人吃得少，活动少。A 为正确答案。The more time scientists spend designing computers, the more they wonder at humanbrain. Tasks that puzzle the most advanced supercomputer-recognizing a face, reading a handwritten note-are child s play. Most important, unlike any ordinary computer, the brain can learn from its mistakes. Researchers have tried for years to program computers to imi-tate the brains abilities, but without success. Now a growing number of designers believe they have the answer: if a computer is to work more like a person and less like an over-grown calculator it must be built more like a brain, which distributes information across a vast interconnected web of nerve cells or neurons.Ordinary computers work by following a chainlike sequence of detailed instructions.Although very fast, their processors can perform only one task at a time. This approach works best in solving problems that can be broken down into simpler logical pieces. The pro-cessors in a neural-network computer,by contrast,form a network much like the nerve :cells in the brain. Since these artificial (人造的) neurons are interconnected, they can share infor-mation and perform tasks at the same time. This two-dimensional approach works best at rec-ognizing patterns.Instead of programming a neural-network computer to make decisions,its maker trains it to recognize patterns in any solution to a problem by repeatedly feeding examples to the machine.Neural networks come in all shapes and sizes. Until now most existed as software simu-lations (模拟品) because redesigning computer chips took a lot of time and money. By exper-imenting with different approaches through software rather than hardware, scientists have been able to avoid costly mistakes.26.It can be inferred from the first paragraph that a computer_.A.can recognize a faceB.cannot learn from its mistakesC.cannot follow detailed instructionsD.can read a handwritten note答案：B27.Which of the following is NOT true about an ordinary computer?A.It must be programmed before it works.B.It can only solve one problem at a time.C.It is good at solving problems that can be broken down into simpler logical pieces.D.It is trained to make decisions.答案：D解析：从第二段开头这句，Ordinary computers work by following a chainlike sequence of detailed instructions(电脑的工作原理就是遵循一系列详细的指令)，可知选项 A是正确的表达。从第二句，Although very fast，their processors can perform only one task at a time，可知 B也是正确的表达。从第三句，This approach works best in solving problems that can be broken down into simpler logical pieces(在处理能够破解为更简单的逻辑编码的问题时，效果最好)，可知选项 C也是正确的表达。另外第三段第一句 Instead of program-ming a neural-network computer to make decisions，its maker trains it to中的 instead of就已经表明了没有给电脑编程去让它做决定，所以选项 D是错误的表达。28.The main feature of a neural-network computer is that_.A.its processors act as an interconnected web of neuronsB.it is programmed to make decisionsC.its networks are of all shapes and sizesD.its neurons are artificial答案：A解析：本题问到神经网络计算机的主要特点，从第二段这句The processors in a neuralnetwork computer，by contrast，form a network much like the nerve cells in the brain可以看出，神经网络计算机的处理器能够形成跟大脑神经细胞很相似的网络，也就是指 interconnected web of neurons(互相交错的神经网)，这正是这种计算机不同于普通计算机最显著的特点。A为正确选项。29.The expression “this two-dimensional approach“ in the second paragraph refers to_.A.the conventional computer and the neural computerB.making decisions and recognizing patternsC.sharing information and performing tasksD.the computer and the human brain答案：C解析：语义词义题。从这个短语前面的这句话 they can share information and perform tasks at the same time可知答案为C。30.Scientists use software rather than hardware in their experiments because_.A.it can avoid redesigning computer chipsB.it can save a lot of time and moneyC.it can avoid making mistakesD.it is more like the human brain答案：B解析：细节判断题。从最后一句 By experimenting with different approaches through software rather than hardware，scientists have been able to avoid costly mistakes可以得知，用软件能够避免一些会导致重大损失的错误。costly，“昂贵的，代价高的”，avoid costly mistakes 也就是指能够节约钱和时间，而不是避免所有错误(故选项 C错误)，答案选 B。The agriculture revolution in the nineteenth century involved two things:the invention of labor-saving machinery and the development of scientific agriculture. Labor-saving natu-rally appeared first where labor was rare. “In Europe“, said Thomas Jefferson,“ the object is to make the most of their land, labor being sufficient; here it is to make the most of our labor,land being abundant. “ It was in America, therefore, that the great advances in nine-teenth-century agricultural machinery first came.At the opening of the century, with the exception of a crude (粗糙的) plow, farmers could have carried practically all of the existing agricultural tools on their backs. By 1860,most of the machinery in use today had been designed in an early form. The most important of the early inventions was the iron plow. As early as 1890 Charles Newbolt of New Jersey had been working on the idea of a cast-iron plow and spent his entire fortune in introducing his invention. The farmers, however, would bring home none of it, claiming that the iron poi-soned the soil and made the weeds grow. Nevertheless, many people devoted their attention to the plow,until in 1869,James Oliver of South Bend, Indiana, turned out the first chilled steel plow.31.The word “here“ refers to_.A.EuropeB.AmericaC.New JerseyD.Indiana答案：B32.Which of the following statement is NOT true?A.The need for labor helped the invention of machinery in America.B.The farmer rejected Charles Newbolt's plow for fear of ruin of their fields.C.Both Europe and America had great need for farm machinery.D.It was in Indiana that the first chilled-steel plow was produced.答案：C解析：细节判断题。文章第一段中有这样的句子：In Europe，the object is to make the most of their land，labor being sufficient，here it is to make the most of our labor，and land being abundant(在欧洲，我们的目标是劳动力充足，要充分利用土地，在美国是土地充足，要正确使用劳动力)。因此，说欧洲和美国都急需农业机械化是错误的。正确答案为 C。33.The passage is mainly about_.A.the agriculture revolutionB.the invention of labor-saving machineryC.the development of scientific agricultureD.the farming machinery in America答案：B解析：主旨概括题。文章第一段讲到农业机器最初产生的原因，第二段讲到铁犁的产生，所以文章的中心思想应当是“节省劳力机器的发明”，选 B。34.At the opening of the nineteenth-century,farmers in America_.A.preferred light toolsB.were extremely self-reliantC.had many toolsD.had very few tools答案：D解析：逻辑推断题。文章中有这样的句子：At the opening of the century，with the exception of a crude plow，farmers could have carried practically all of the existing agri-cultural tools on their backs(在本世纪初，除了一个粗糙的耕犁之外，农民可以把其余所有的农具背在背上)。说明当时的农具很少。D 为正确答案。35.It is implied but not stated in the passage that_.A.there was a shortage of workers on American farmsB.the most important of the early invention was the iron plowC.many people devoted their attention to the plowD.Charles Newbolt had made a fortune by his cast-iron plow答案：A解析：逻辑推断题。从文章第二段的 The most important of the early inven-tions was the iron plow可以看出 B是明确表明了的;从这句 Nevertheless，many people de-voted their attention to the plow来看，C 也是原文给出了的;从这句Charles Newbolt of New Jersey had been working on the idea of a cast-iron plow and spent his entire fortune in intro-ducing his invention可以得知 D也是原文明确表明的;从第一段here it is to make the most of our labor，land being abundant(充分利用劳动力，土地资源丰富)，可以推断出劳动力缺乏，所以 A是文章暗含的内容。Most women in Ghana-the educated and illiterate, the urban and rural, the young and old-work to earn an income in addition to maintaining their roles as housewives and moth-ers. Their reputation for economic independence, self-reliance ,and hard work is well known and well deserved.Most of Ghanas working women are farmers and traders. Only one woman in five, or even fewer, can be classified as simply housewives. Even these women often earn money by sewing or by baking and cooking things to sell. They also maintain vegetable gardens and chicken farms. Indeed, the woman who depends entirely upon her husband for support is looked upon with disfavor.Traditionally the tasks of motherhood have been shared. Mothers and sisters, grand-mothers and nieces all helped to raise the children and to carry out daily tasks. As the family grew,older brothers and sisters also helped to care for the younger ones and helped in the home. Now with more children going to school, with more people moving away from their traditional homes, not only must the mother continue her income-producing activities, but she must take on all the heavy, time-consuming housework.Ghana today is looking for new ways to meet the needs of women and their families, such as providing more day care centers, so women can continue to play their multiple roles in the home and in the economy.36.What is the role of most women in Ghana?A.Handling various housework at home.B.Taking care of children indoors.C.Farming and trading out of house.D.Working as well as maintaining families.答案：D37.“Self-reliance“ could be explained as “_”.A.making great wealthB.depending on oneselfC.caring for one's ownD.being a reliable person答案：B解析：语义词义题。从第一段可以得知加纳的女性既要承担家庭主妇的责任，又要工作赚钱，可以得知她们是靠自己的，所以选B。另外从单词本身来看，self-表示“自己的”，reliance 来自动词 rely(依靠)，也可以推断出表示“依靠自己”。38.What kind of women do people in Ghana prefer?A.Beautiful and charming.B.Skillful at sewing or baking.C.Depending totally on husbands.D.Working hard to earn incomes.答案：D解析：逻辑推断题。从第一段最后一句可以看出，自力更生又努力工作的女性是受到人们的认可和尊敬的;第二段最后一句，Indeed，the woman who depends entirely up-on her husband for support is looked upon with disfavor(完全依靠丈夫来养家的女性是不被人们赞同，并被人看不起的)，也表明本题答案应选D。39.Paragraph 3 intends to tell us_.A.how traditional extended families operate
