1、Section CPassage OneQuestions 57 to 61 are based on the following passage.Across the rich world, well-educated people increasinglywork longer than the less-skilled. Some65%of American menaged 62-74 with a professional degree are in the workforce, compared with 32% of men with only a high-school cert

Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound.The world is facing a

Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion.The experience of the20th century, whengreater longevity( 長壽)translated into moreyears in ret

5、 growing gap between the skilled and the unskilled. Employment rates are failing amongyounger unskilled people, whereas older skilled folk are working longer.The divide is most extreme in America, where well-educated baby-boomers( 二 戰(zhàn) 后 生 育 高 峰 期 出 生 的 美 國 人 )areputting off retirement while many les

6、s-skilled younger people have abandoned policies that used Xto retire early.Rising life expectancy( 預期生命),combined with the replace-Xpension plans with less generous defined-contribution ones, means that even the better-off must work longer to have a comfortable retirement. But the changing nature o

7、f work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap rich rewards into old age because these days the educated elderly are more productive that the preceding generation. Technological charge may well reinforce that shift; the skills that comp

One e

13、xample comes from agriculture. Food riots and hunger make news. But the trend lying behind these matters is rarely talked about. This is the decline in the growth in yields of someof the world's major crops. A new study by the University of Minnesota and McGill University in Montreal looks at wh

14、ere, and how far, this decline is occurring.The authors take a vast number of data points for the four most important crops: rice, wheat, corn and soyabeans( 大豆 ). They find that on between 24% and 39% of all harvested areas, the improvement in yields that took place before the 1980s slowed down in

15、the 1990s and 2000s.There are two worrying features of the slowdown. One is that it has been particularly sharp in the world's most populous( 人 口 多 的 )countries, India and China. Their ability to feed themselves has been an important source of relative stability both within the countries and on

16、world food markets. That self-sufficiencycannot be taken for granted if yields continueto slow down or reverse.Second,yield growth has been lower in wheat and rice than in corn and soyabeans. This is problematic because wheat and rice are more important as foods, accounting for around half of all ca

17、lories consumed. Corn and soyabeans are more important as feed grains. The authors note that "we have preferentially focused our crop improvement efforts on feeding animals and cars rather than on crops that feed people and are the basis of food security in much of the world."The report qu

18、alifies the more optimistic findings of another new paper which suggests that the world will not have to digup a lot more land for farming in order to feed 9 billion people in 2050, as the Food and Agriculture Organisation has argued.Instead, it says, thanks to slowing population growth, land curren

19、tly ploughed up for crops might be able to revert( 回返 )to forest or wilderness. This could happen. The trouble is that the forecast assumes continued improvements in yields, which may not actually happen.62.What does the author try to draw attention toA.Food riots and hunger in the world.B.The decli

20、ne of the grain yield growth.C.News headlines in the leading media.D.The food supply in populous countries.【答案】B63.Why does the author mention India and China in particularA.Their self-sufficiency is vital to the stability of world food markets.B.Their food yields have begun to decrease sharply in r

21、ecent years.C.Their big populations are causing worldwide concerns.D.Their food self-sufficiency has been taken for granted.【答案】 A64.What does the newstudy by the two universities say about recent crop improvement effortsA.They fail to produce the same remarkableresults asbefore the 1980s.B.They con

22、tribute a lot to the improvement of human food production.C.They play a major role in guaranteeing the food security of the world.D.they focus more on the increase of animal feed than human food grains.【答案】 D65 .What does the Food and Agriculture Organisation say about world food production in the c

23、oming decadesA.The growing population will greatly increase the pressure on world food supplies.B.The optimistic prediction about food production should be viewed with caution.C.The slowdown of the growth in yields of major food crops will be reversed.D.The world will be able to feed its population

25、estion 57 to 61 are based on the following passage.If you think a high-factor sunscreen( 防曬霜 )keeps you safe from harmful rays, you may be wrong. Research in this week's Nature shows that while factor 50 reduces the number of melanomas(M 瘤)and delays their occurrence, it can't prevent them.

26、Melanomasare the most aggressive skin cancers. You have a higher risk if you have red or blond hair, fair skin, blue or green eyes, or sunburn easily, or if a close relative has had one. Melanomasare more commonif you have periodic intense exposure to the sun. Other skin cancers are increasingly lik

27、ely with long-term exposure.There is continuing debate as to how effective sunscreenis in reducing melanomas the evidence is weaker than it is forpreventing other types of skin cancer. A 2011 Australian study of 1,621 people found that people randomly selected to apply sunscreen daily had half the r

28、ate of melanomas of people who used cream as needed. A second study, comparing 1,167 people with melanomasto 1,101 who didn't have the cancer, found that using sunscreen routinely, alongside other protection such as hats, long sleeves or staying in the shade, did give some protection. This study

29、 said other forms of sun protectionnot sunscreen seemed most beneficial. The study relied on people remembering what they had done over each decade of their lives, so it's not entirely reliable. But it seems reasonable to think sunscreen gives people a false sense of security in the sun.Many peo

30、ple also don't use sunscreen properly-applying insufficient amounts, failing to reapply after a couple of hours and staying in the sun too long. It is sunburn that is most worrying-recent shows five episodes of sunburn in the teenage years increases the risk of all skin cancers.The good news is

31、that a combination of sunscreen and covering up can reduce melanoma rates, as shown by Australianfigures from their slip-slop-slap campaign. So if there is aheat wave this summer, it would be best for us, too, to slip on a shirt, slop on( 抹上 )sunscreen and slap on a hat.57. 【 題 干 】 What is people

39、or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity( 長 壽 )translated into more years in retirement rather than more years at work, has persuaded manyobservers that this shift will lead to slower economic growth, while the swelling r

Many European governments have abandoned policies that used to encourage people to retire early. Rising life expectan
