34、 a letter. Answer the questions by marking the corresp onding letter on An swer Sheet 2In Hard Economy for All Ages, Older Isn'Better. It ' BrutalA Young graduates are in debt, out of work and on their parents couches. People intheir 30s and 40s ca'afford to buy homes or have childre n.

36、）as the greatest victims of the recession and its dreadful con seque nces.C These America ns in their 50s and early 60s those n ear retireme nt age who donot yet have access to Medicare and Social Security have lost the most earnings power of any age group, with their household in comes 10 perce nt

37、below what they made whe n the recovery bega n three years ago, accord ing to Sen tier Research, a data an alysis compa ny. Their retireme nt sav ings and home values fell sharply at the worst possible time: just before they n eeded to cash out. They are support ing both aged pare nts and un employe

38、d youn g-adult childre n, earning them the uniucky nickname Generation Squeeze.D New research suggests that they may die sooner, becausetheir health, in come security and mental well-being were battered （重仓U） by recession at a crucial time in their lives. A rece nt study by econo mists at Wellesley

39、College found that people who lost their jobs in the few years before becoming qualified for Social Security lost up to three years from their life expectancy （预期寿命）,largely because they no Ion ger had access to affordable health care.E Un employme nt rates for America ns n eari ng retireme nt are f

40、ar lower tha n those for young people, who are recently out of school, with fewer skills and a shorter work history. But once out of a job, older workers have a much harder time finding another one. Over the last year, the average duration of unemployment for older people was 53 weeks, compared with

41、 19 weeks for tee nagers, accordi ng to the Labor Departme nfs jobs report released on Friday.F The len gthy process is partly because older workers are more likely to have bee nlaid off from in dustries that are dow nsiz in g, like manu facturi ng. Compared with the rest of the population, older pe

42、ople are also more likely to own their own homes and be less mobile tha n ren ters, who can move to new job markets.G Older workers are more likely to have a disability of some sort, perhaps limit ing the range of jobs that offer realistic choices. They may also be less in cli ned, at least in itial

43、ly, to take jobs that pay far less tha n their old positi ons.H Displaced boomers also believe they are victims of age discrim in ati on, because employers can easily find a young, en ergetic worker who will accept lower pay and who can pote ntially stick around for decades rather tha n a few years.

44、I In a survey of older workers who were laid off during the recession, just one in sixhad found ano ther job, and half of that group had accepted pay cuts. 14% of the re-employed said the pay in their new job was less tha n half what they earned in their previous job. “just say to myself: Why me? Wh

45、at have I done to deserve this?'”aid John Agati, 56, whose last full-time job, as a product developer, en ded four years ago whe n his employer went out of bus in ess. That positi on paid $90,000, and his resume lists jobs at compa nies like America n Express, Disney and USA Networks. Since bein

46、g laid off, though, he has worked a series of part-time, low-wage, temporary positions, including selling shoes at Lord & Taylor and making sales calls for a car compa ny.J The last few years have take n a toil not only on his family 's finan ces, but also onhis feelings of self-worth. You j

47、ust get sad” Mr. Agati said. “ see people gett ing up in the morning, going out to their careers and going home. I just wish I was doing that. Some people don't like their jobs, or they have problems with their jobs, but at least they're work in g. I just wish I was in their shoes. ” He said

48、 he cannot afford to go back to school, as many youn ger people without jobs have done. Eve n if he could afford it, econo mists say it is un clear whether older workers like him ben efit much from more educatio n.K “ just doesn't make sense to offer retra ining for people 55 and older,” said Da

49、niel Hamermesh, an economics professor. Discrimination by age, long-term un employme nt, and the fact that they're now at the end of the hiri ng queue just don 'make it sen sible to in vest in them”L Many displaced older workers are taking this messageto heart and leaving the labor force en

50、tirely. The share of older people appl ying for Social Security early rose quickly duri ng the recessi on as people sought whatever in come they could find. The pen alty they will pay is perma nent, as retirees who take ben efits at age 62 will receive as much as 30% less in each month ' check f

51、or the rest of their lives than they would if they had waited until full retirement age (66 for those born after 1942).M Those not yet qualified for Social Security are increasingly applying for another, comparable kind of in come support that ofte n goes to people who expect n ever to work aga in:

52、disability ben efits. More tha n one in eight people in their late 50s is now on some form of federal disability in sura nce program, accord ing to Professor Mark Dugga n at the Un iversity of Penn sylva nia's Whart on School.N The very oldest America ns, of course, were battered by some of the

53、same ill wi nds that torme nted （折磨）those now n eari ng retireme nt, but at least the most senior were cushioned by a more readily available social safety net. More important, in a statistical twist, they may have actually benefited from the finan cial crisis in the most fun dame ntal way: Ion ger l

54、ives.O Death rates for people over 65 have historically fallen during recessions, accordi ng to a November2011 study by econo mists at the Uni versity of Califor nia, Davis. Why? The researchersargue that weak job markets push more workers into accept ing relatively un desirable work at nursing home

55、s, lead ing to better care for reside nts.46. Greater mobility puts youn ger people at an adva ntage in seek ing new jobs.47. Many of the older workers laid off duri ng the recessi on had to accept lower pay in their new jobs.48. Those who lose their jobs shortly before retireme nt age live a shorte

56、r-tha n-average life.49. Seniors at nursing homes could ben efit from the weak job market.50. Age discrim in ati on in employme nt makes it poin tless retra ining older workers.51. Accord ing to rece nt reports and data an alyses, boomers suffer most from the weak economy.52. Un employed boomers are

57、 at a disadva ntage in job-hu nti ng because employers tend to hire youn ger workers.53. People in their fifties and early sixties bear the heaviest family burdens.54. People who take ben efits from Social Security before official retireme nt age will get much less for the rest of their lives.55. Ol
