Section C 26 Every year, IBM Corpora
14、tion chooses five new technologies it believes will change the world within the next five years. The IBM list is called “ Five in Five. “ The company says it【 B1】 _its own research and the new directions of society and business when identifying the technologies. This year, the list describes some fu
15、ture devices that will extend our five senses. Imagine【 B2】 _clothes online and touching your computer or smartphone to feel the cloth. IBM Vice President Bernie Meyerson predicts that technology could be【 B3】_in the next five years. Touch is just one of the senses that computers will help to【 B4】 _
16、. IBM says smart machines will soon be able to【 B5】 _the environment and give us information about the sounds they hear. For example, Bernie Meyerson says an【 B6】_speech recognition system will tell new parents why their baby is crying and smart machines will also help identify medical conditions. I
17、f you【 B7】 _on your computer or cell phone, the machine will study【 B8】 _molecules in your breath. Then it can tell you whether you need to see a doctor. In the near future, built-in cameras in our personal computers will be able to examine and name colors and recognize images. Mr. Meyerson says IBM
18、 scientists are also developing a computer system that can examine and【 B9】 _food molecules to create the most popular flavors and smells. Mark Maloof is a computer science professor at Georgetown University. He says he hopes the progress that IBM is【 B10】 _will lead more students to create future i

Professor Maloof says advances in computer technology will make what now seems like science fiction a part of our everyday lives. 27 【 B1】 28 【 B2】 29 【 B3】 30 【 B4】 31 【 B5】 32 【 B6】 33 【 B7】 34 【 B8】 35 【 B9】 36 【 B10】 Section A 36 When studying human talent, the temptation is usually t
20、o concentrate on the upper reaches. Understandably so: we all admire the Einsteins and Mozarts of this world and【 C1】 _to imitate them. In comparison, studying the opposite end of the spectrum might seem pointless, patronizing(摆出恩赐态度的 )ox downright tasteless. Lack of intelligence is shameful enough
21、without treating people like lab rats. Yet it often takes a different viewpoint to find new insights into an old problem. Stupidity is too important and interesting to ignore. The science of stupidity is producing results that【 C2】 _our concepts of intelligence and that should be humbling for many o
22、f the smart people who run the world. It turns out that a tendency for entertaining【 C3】 _, foolish or illogical ideas is not necessarily the result of a low IQ. This measure of intelligence is largely【 C4】_of rationality. Just because you score on the high end of one scale doesnt mean that you wont
23、 fall at the bottom of the other. Importantly, no one is【 C5】 _to the biases that lead to stupid decisions. Yet our respect for IQ and education means that it is easy to rest on the laurels(桂冠 )of our qualifications and assume that we are, by definition, not stupid. That can be【 C6】 _on a personal l
24、evel: regardless of IQ, people who score badly on rationality tests are more likely to have unplanned pregnancies or fall into serious debt. Large scale stupidity is even more damaging. Business cultures that【 C7】_encourage it, for example, may have contributed to the economic crisis. Indeed, the ef
25、fects may have been so damaging precisely because banks assumed that intelligent people act logically while at the same time rewarding rash behavior based on intuition rather than【 C8】 _. As one researcher puts it: “The more intelligent someone is, the more disastrous the results of their stupidity“
26、. The same surely applies to politicians: the tenth anniversary of the invasion of Iraq serves as a【 C9】 _that clever people can do monumentally stupid things. If we want to avoid making similar mistakes in the future, everybody especially the most intelligent and powerful would do well to humbly【 C

AIf you want to spark a heated debate at a dinner party, bring up the topic about genetically modified foods. For many people, the concept of genetically altered, high-tech crop prod
29、uction raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions and vocal green lobbies the idea seems against nature. BIn fact, genetically modified foods are already very much a part of our lives. A third of the corn and more
30、than half the soybeans and cotton grown in the U. S. last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the U. S. this year. The genetic is out of the bottle. CYet there are clearly some
31、 very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from and a supply that far e
32、xceeds our needs. In developing countries desperate to feed fast-growing and underfed populations; the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risks? DThe statistics on population growth and hunger are disturbing. Last year the worlds population reached 6 billi
33、on. And by 2050, the UN estimates, it will be probably near 9 billion. Almost all that growth will occur in developing countries. At the same time, the worlds available cultivable land per person is declining. Arable land has declined steadily since 1960 and will decrease by half over the next 50 ye
34、ars, according to the International Service for the Acquisition of Agri-Biotech Applications(ISAAA). How can biotech help? EBiotechnologists have developed genetically modified rice that is fortified with beta-carotene( - 胡萝卜素 ) which the body converts into vitamin A and additional iron, and they ar
35、e working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attribution to pests, drought, poor soil and crop viruses, bacteria or fungi(真菌 ). FDamage caused by pests is incredible. The European corn
36、 borer, for example, destroys 40 million tons of the worlds corn crops annually, about 7% of the total. Incorporating pest-resistant genes into seeds can help restore the balance. In trials of pest-resistant cotton in Africa, yields have increased significantly. So far, fears that genetically modifi
37、ed, pest-resistant crops might kill good insects as well as bad appear unfounded. GViruses often cause massive failure in staple crops in developing countries. Two years ago, Africa lost more than half its cassava(树薯 )crop a key source of calories to the mosaic virus(花叶病毒 ). Genetically modified, vi
38、rus-resistant crops can reduce that damage, as can drought-tolerant seeds in regions where water shortages limit the amount of land under cultivation. Biotech can also help solve the problem of soil that contains excess aluminum, which can damage roots and cause many staple-crop failures. A gene tha
39、t helps neutralize aluminum toxicity(毒性 )in rice has been identified. Many scientists believe biotech could raise overall crop productivity in developing countries as much as 25% and help prevent the loss of those crops after they are harvested. HYet for all that promise, biotech is far from being t
40、he whole answer. In developing countries, lost crops are only one cause of hunger. Poverty plays the largest role. Today more than 1 billion people around the globe live on less than 1 dollar a day. Making genetically modified crops available will not reduce hunger if farmers cannot afford to grow t
41、hem or if the local population cannot afford to buy the food those farmers produce. IBiotech has its own “distribution“ problems. Private-sector biotech companies in the rich countries carry out much of the leading-edge research on genetically modified crops. Their products are often too costly for
42、poor farmers in the developing world, and many of those products wont even reach the regions where they are most needed. Biotech firms have a strong financial incentive to target rich markets first in order to help them rapidly recoup the high costs of product development. But some of these companie
43、s are responding to needs of poor countries. JMore and more biotech research is being carried out in developing countries. But to increase the impact of genetic research on the food production of those countries, there is a need for better collaboration between government agencies both local and in
44、developed countries and private biotech firms. The ISAAA, for example, is successfully partnering with the U. S. Agency for International Development, local researches and private biotech companies to find and deliver biotech solutions for farmers in developing countries. Will “Franken-foods“ feed t
45、he world? KBiotech is not a panacea(治百病的药 ), but it does promise to transform agriculture in many developing countries. If that promise is not fulfilled, the real losers will be their people, who could suffer for years to come. LThe world seems increasingly to have been divided into those who favor
46、genetically modified foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering which can induce plants to grow in poor soils or to produce more
47、nutritious foods will soon become an essential tool for helping to feed the worlds burgeoning(迅速发展的 )population. Skeptics contend that genetically modified crops could pose unique risks to the environment and to healthrisks too troubling to accept placidly. Taking that view, many European countries
48、are restricting the cultivation and importation of genetically modified agricultural products. Much of the debate are concerned about of safety. But what exactly does recent scientific research say about the hazards? MTwo years ago in Edinburgh, Scotland, eco-vandals stormed a field, crushing canola
49、 plants. Last year in Maine, midnight raiders hacked down more than 3,000 experimental poplar trees. And in San Diego, protesters smashed sorghum and sprayed paint over greenhouse walls. This far-flung outrage took aim at genetically modified crops. But the protests backfired: all the destroyed plants were conventionally bred. In each case, activists mistook ordinary plants for genetically modified varieties. NIts
