8、et 2.The Changes Facing Fast FoodA） Fast-food firms have to be a thick-skinned bunch. Health experts regularly criticize them severely for selling food that makes people fat. Critics even complain that McDonalds, whose logo symbolizes calorie excess, should not have been allowed to sponsor the World

9、 Cup. These are things fast-food firms have learnt to cope with. But not perhaps for much longer. The burger business faces more pressure from regulators at a time when it is already adapting strategies in response to shifts in the global economy.B) Fast food was once thought to be recession-proof.

10、When consumers need to cut spending, the logic goes, cheap meals like Big Macs and Whoppers become even more attractive. Such trading down” proved true for much of the latest recession, when fast-food companies picked up customers who could no longer afford to eat at casual restaurants. Traffic was

11、boosted in America, the home of fast food, with discounts and promotions, such as $1 menus and cheap combination meals.C) As a result, fast-food chains have weathered the recession better than their more expensive competitors. In 2009 sales at full-service restaurants in America fell by more than 6%

12、 , but total sales remained about the same at fast-food chains. In some markets, such as Japan, France and Britain, total spending on fast food increased. Same-store sales in America at McDonalds, the worlds largest fast-food company, did not decline throughout the downturn. Pan era Bread, an Americ

13、an fast-food chain known for its fresh ingredients, performed well, too, because it offers higher-quality food at lower prices than restaurants.D) But not all fast-food companies have been as fortunate. Many, such as Burger King, have seen sales fall. In a severe recession, while some people trade d

14、own to fast food, many others eat at home more frequently to save money. David Palmer, an analyst at UBS, a bank, says smaller fast- food chains in America, such as Jack in the Box and Carls Jr., have been hit particularly hard in this downturn because they are competing with the global giant McDona

15、lds, which increased spending on advertising by more than 7% last year as others cut back.E） Some fast-food companies also sacrificed their own profits by trying to give customers better value. During the recession companies set prices low, hoping that once they had tempted customers through the doo

16、r they would be persuaded to order more expensive items. But in many cases that strategy did not work. Last year Burger King franchisees (特许经营人)sued (起诉)the company over its double-cheeseburger promotion, claiming it was unfair for them to be required to sell these for $1 when they cost$1.10 to make

17、. In May a judge ruled in favor of Burger King. Nevertheless, the company may still be cursing its decision to promote cheap choices over more expensive ones because items on its value menu now account for around 20% of all sales, up from 12% last October.F） Analysts expect the fast-food industry to

18、 grow modestly this year. But the downturn is making companies rethink their strategies. Many are now introducing higher-priced items to entice (引诱)consumers away from $1 specials.KFC, a division of Yum! Brands, which also owns Taco Bell and Pizza Hut, has launched a chicken sandwich that costs arou

19、nd $5.And in May Burger King introduced barbecue (烧烤)pork ribs at $7 for eight.G）Companies are also trying to get customers to buy new and more items, including drinks. McDonalds started selling better coffee as a challenge to Starbucks. Its Mc Cafe line now accounts for an estimated 6% of sales in

20、America. Starbucks has sold rights to its Seattles Best coffee brand to Burger King, which will start selling it later this year.H) As fast-food companies shift from super size to more buys, they need to keep customer traffic high throughout the day. Many see breakfast as a big opportunity, and not

21、just for fatty food. McDonalds will start selling porridge (粥)in America next year. Breakfast has the potential to be very profitable, says Sara Senator of Bernstein, a research firm, because the margins can be high. Fast-food companies are also adding midday and late-night snacks, such as blended d

22、rinks and wraps. The idea is that by having a greater range of things on the menu, we can sell to consumers products they want all day, says Rick Carlucci., the .chief financial officer of Yum ! Brands.I) But what about those growing waistlines? So far, fast-food firms have cleverly avoided governme

23、nt regulation. By providing healthy options, like salads and low-calorie sandwiches, they have at least given the impression of doing something about helping to fight obesity (肥胖症).These offerings are not necessarily loss-leaders, as they broaden the appeal of outlets to groups of diners that includ

24、e some people who dont want to eat a burger. But customers cannot be forced to order salads instead of fries.J) In the future, simply offering a healthy option may not be good enough.Every packaged-food and restaurant company I know is concerned about regulation right now, says Mr. Palmer of UBS. Am

25、ericas health-reform bill, which Congress passed this year, requires restaurant chains with 20 or more outlets to put the calorie-content of items they serve on the menu. A study by the National Bureau of Economic Research, which tracked the effects on Starbucks of a similar calorie-posting law in N

26、ew York City in 2007, found that the average calorie-count per transaction fell 6% and revenue increased 3% at Starbucks stores where a Dunlin Donuts outlet was nearby-a sign, it is said, that menu-labeling could favor chains that have more healthy offerings.K) In order to avoid other legislation in

27、 America and elsewhere, fast-food companies will have to continue innovating (创新).Walt Riker of McDonalds claims the change it has made in its menu means it offers more healthy items than it did a few years ago.We probably sell more vegetables, more milk, more salads, more apples than any restaurant

28、 business in the world, he says. But the recent proposal by a county in California to ban McDonalds from including toys in its high-calorie” Happy Meals, because legislators believe it attracts children to unhealthy food, suggests there isa lot more left to do.46.Some people propose laws be made to

29、stop McDonalds from attaching toys to its food specials for children.47. Fast-food fins may not be able to cope with pressures from food regulation in the near future.48. Burger King will start to sell Seattles Best coffee to increase sales.49. Some fast-food firms provide healthy food to give the i

30、mpression they are helping to tackle the obesity problem.50. During the recession, many customers turned to fast food to save money.51. Many people eat out less often to save money in times of recession.52. During the recession, Burger Kings promotional strategy of offering low-priced items often pr

31、oved ineffective.53. Fast-food restaurants can make a lot of money by selling breakfast.54. Many fast-food companies now expect to increase their revenue by introducing higher-priced items.55. A newly-passed law asks big fast-food chains to specify the calorie count of what they serve on the menu.Se

32、ction CPassage OneQuestions 56 to 60 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 weeks Nature shows that while factor 50 reduces the number of melanomas(黑瘤)and delays their occurrence, it cant preve

33、nt 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 incr

34、easingly 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

35、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 didnt 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.

36、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 its not entirely reliable. But it seems reasonable to think sunscreen gives people a false sense of security in the sun.Ma

37、ny people also dont 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 research shows five episodes of sunburn in the teenage years increases the risk of all skin cancers.The goo

38、d 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.56. What is people

39、s common expectation of a high-factor sunscreen?A. It will delay the occurrence of skin cancer.B. It will protect them from sunburn.C. It will keep their skin smooth and fair.D. It will work for people of any skin color.57. What does the research in Nature say about a high-factor sunscreen?A. It is

40、ineffective in preventing melanomas.B. It is ineffective in case of intense sunlight.C. It is ineffective with long-term exposure.D. It is ineffective for people with fair skin.58. What do we learn from the 2011 Australian study of 1,621 people?A. Sunscreen should be applied alongside other protecti

41、on measures.B High-risk people benefit the most from the application of sunscreen.C. Irregular application of sunscreen does women more harm than good.D. Daily application of sunscreen helps reduce the incidence of melanomas.59. What does the author say about the second Australian study?A. It mislea

42、ds people to rely on sunscreen for protection.B. It helps people to select the most effective sunscreen.C. It is not based on direct observation of the subjects.D. It confirms the results of the first Australian study.60. What does the author suggest to reduce melanoma rates?A. Using both covering u

43、p and sunscreen.B. Staying in the shade whenever possible.C. Using covering up instead of sunscreen.D. Applying the right amount of sunscreen.Passage TwoQuestions 61 to 65 are based on the following passage.Across the rich world, well-educated people increasingly work longer than the less-skilled.So

44、me65% of American men aged 62 -74 with a professional degree are in the workforce, compared with32% 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

45、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 wi

46、ll almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity (长寿)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 pen

47、sioners 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. Employment rates are falling among younger unskilled people, whereas older skilled folk are working

48、longer. The divide is most extreme in America, where well-educated baby-boomers (二战后生育高峰期出生的美国人)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 p

49、eople to retire early. Rising life expectancy (预期寿命), combined with the replacement of generous defamed-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 high
