　　Section C

　　Passage One

　　Question 57 to 61 are based on the following passage.

　　If you think a high-factor sunscreen(防晒霜)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(黑瘤)and delays their occurrence, it can"t prevent them. Melanomas are 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. Melanomas are more common if you have periodic intense exposure to the sun. Other skin cancers are increasingly likely with long-term exposure.

　　There is continuing debate as to how effective sunscreen is in reducing melanomas—the evidence is weaker than it is for preventing 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 rate of melanomas of people who used cream as needed. A second study, comparing 1,167 people with melanomas to 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 said other forms of sun protection—not 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 people 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 that a combination of sunscreen and covering up can reduce melanoma rates, as shown by Australian figures from their slip-slop-slap campaign. So if there is a heat 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.

　　Passage Two

　　Questions 62 to 65are based on the following passage.

　　Across the rich world, well-educated people increasingly work longer than the less-skilled. Some 65% of American men aged 62-74 with a professional degree are in the workforce, compared with 32% of men with only a high-school certificate. This gap is part of a deepening divide between the well-educated well-off and the unskilled poor. 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 an astonishing rise in the number of old people, and they will live longer than ever before. 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 the 20th century, when greater longevity(長壽)translated into more years in retirement rather than more years at work, has persuaded many observers that this shift will lead to slower economic growth, while the swelling ranks of pensioners will create government budget problems.

　　But the notion of a sharp division between the working young and the idle old misses a new trend, the growing gap between the skilled and the unskilled people, whereas older skilled folk are working longer. The divide is most extreme in America, where well-educated baby-boomers(二戰後生育高峰期出生的美國人)are putting off retirement while many less-skilled younger people have dropped out of the workforce.

　　Policy is partly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Rising life expectancy(預期壽命), combined with the replacement of generous defined-benefit pension 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 of 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 than the preceding generation. Technological change may well reinforce that shift: the skills that complement computers, from management knowhow to creativity, do not necessarily decline with age.

　　62.【題干】What is happening in the workforce in rich countries?

　　A.Younger people are replacing the elderly.

　　B.Well-educated people tend to work longer.

　　C.Unemployment rates are rising year after year.

　　D.People with no college degree do not easily find work.
