But there will be others as well. Here is one of the remarkable therapies on the cutting edge of
10、genetic research that could make their way into mainstream medicine in the coming years.While its true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells
11、is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so-called stem cells havent begun to specialize.Yet this untapped potential could be a terrific boon to medici
12、ne. Most diseases involve the death of healthy cellsbrain cells in Alzheimers, cardiac cells in heart disease, pan creatic cells in diabetes, to name a few. If doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue.It was in
13、credibly difficult, but last fall scientists at the University of Wisconsin man aged to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still cant be controlled, and may have unforeseen limitations; but if ef forts to understand and master stem-cell devel
14、opment prove successful, doctors will have a therapeutic tool of incredible power.The same applies to cloning, which is really just the other side of the coin; true clo ning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, reset
15、ting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full-fledged animal, ge netically identical to its parent.For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market v
16、alue, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year.Human cloning, on the other hand, may be technically feasible but
17、 legally and emo tionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells, the potential to make healthy body tissues of all sorts, and thus to cure disease.
18、That could prove to be a true “miracle cure. /（分数：5.00）(1).The writer holds that the potential to make healthy body tissues will_.（分数：1.00）A.aggravate moral issues of human cloningB.bring great benefits to human beingsC.help scientists decode body instructionsD.involve employing surgical instruments
19、(2).The word “rejuvenated“ ( Par（分数：1.00）A.5 ) most probably means_.A. modifiedB. re-collectedC. classifiedD. reactivated(3).The research at the University of Wisconsin is mentioned to show_.（分数：1.00）A.the isolation of stem cellsB.the effects of gene therapiesC.the advantages of human cloningD.the l
20、imitations of tissue replacements(4).Which of the following is true according to the text?（分数：1.00）A.The principle of gene therapy is applicable to that of cloning.B.The isolation of stem cells is too difficult to be feasible.C.It is reasonable for all body instructions to be activated.D.Cloned anim
21、als will eventually take control of the worl(5).Towards the genetic research, the authors attitude can best be said to be that of_.（分数：1.00）A.frustrationB.indifferenceC.amazementD.opposition1What our society suffers from most today is the absence of consensus about what it and life in it ought to be
22、; such consensus cannot be gained from societys present stage, or from fantasies about what it ought to be. For that the present is too close and too diversi lied, and the future too uncertain, to make believable claims about it. A consensus in the present hence can be achieved only through a shared
23、 understanding of the past, as Homers epics informed those who lived centuries later what it meant to be Greek, and by what images and ideals they were to live their lives and organize their societies.Most societies derive consensus from a long history, a language all their own, a com mon religion,
24、common ancestry. The myths by which they live are based on all of these. But the United States is a country of immigrants, coming from a great variety of na tions. Lately, it has been emphasized that an asocial, narcissistic personality has become characteristic of Americans, and that it is this typ
25、e of personality that makes for the lack of well-being, because it prevents us from achieving consensus that would counteract a tendency to withdraw into private worlds. In this study of narcissism, Christopher Lash says that modern man, “tortured by self-consciousness, turns to new therapies not to
26、 free himself of his personal worries but to find meaning and purpose in life, to find something to live for“. There is widespread distress because national morale has declined, and we have lost an earlier sense of national vision and purpose.Contrary to rigid religions or political beliefs, as are
27、found in totalitarian societies, our culture is one of the great individual differences, at least in principle and in theory; but this leads to disunity, even chaos. Americans believe in the value of diversity, but just because ours is a society based on individual diversity, it needs consensus abou
28、t some dom- inating ideas more than societies based on uniform origin of their citizens. Hence, if we are to have consensus, it must be based on a mytha vision about a common experience, a conquest that made us Americans, as the myth about the conquest of Troy formed the Greeks. Only a common myth c
29、an offer relief from the fear that life is without meaning or purpose. Myths permit us to examine our place in the world by comparing it to a shared idea. Myths are shared fantasies that form the tie that binds the individual to other mem bers of his group. Such myths help to ward off feelings of is
30、olations, guilt, anxiety, and purposelessnessin short, they combat isolation and the breakdown of social standards and values.（分数：5.00）(1).In the eyes of the author, the greatest trouble with the US society may lie in_.（分数：1.00）A.the non-existence of consensus on the forms the society should takeB.t
31、he lack of divergence over the common organizations of social lifeC.the non-acceptance of a society based on individual diversityD.the pervasive distress caused by national morale decline(2).The asocial personality of Americans may stem from_.（分数：1.00）A.the absence of a common religion and ancestryB
32、.the multiracial constituents of the US societyC.the want of a shared myths they possess in lifeD.the counterbalance to narcissistic personality(3).Homers epics is mentioned in Paragraph 1 in order to_.（分数：1.00）A.exemplify the contributions made by ancient poetsB.illustrate the role of shared fantas
33、ies about societyC.show an ideal stage of eternal social progressD.make known myths of what a society ought to be(4).The author concludes that only shared myths can help Americans_.（分数：1.00）A.to bring about the uniformity of their cultureB.to regain their consensus about a common experienceC.to stay
34、 away from negative feelings in their lifeD.to counteract the effects of consensus about society(5).It can be inferred from Paragraph 2 that Christopher Lash is most probably_.（分数：1.00）A.a reform advocateB.a senior psychologistC.a reputed poetD.a social historian3The early retirement of experienced
35、workers is seriously harming the U. S. economy, according to a new report from the Hudson Institute, a public policy research organization. Currently, many older experienced workers retire at an early age. According to the recently issued statistics, 79 percent of qualified workers begin collecting
36、retirement benefits at age 62; if that trend continues, there will be a labor shortage that will hinder the economic growth in the twenty-first century.Older Americans constitute an increasing proportion of the population, according to the U. S. Census Bureau, and the population of those over age 65
37、 will grow by 60% be tween 200 and 2020. During the same period, the group aged 18 to 44 will increase by only 4%. Keeping older skilled workers employed, even part time, would increase U. S. economic output and strengthen the tax base; but without significant policy reforms, massive early retiremen
38、t among baby boomers seems more likely.Retirement at age 62 is an economically rational decision today. Social Security and Medicaid earnings limits and tax penalties subject our most experienced workers to margin al tax rates as high as 67%. Social Security formulas encourage early retirement. Alth
39、ough incomes usually rise with additional years of work, any pay increases after the 35-year mark result in higher social Security taxes but only small increases in benefits.Hudson Institute researchers believe that federal tax and benefit policies are at fault and reforms are urgently needed, but t
40、hey disagree with the popular proposal that much older Americans will have to work because Social Security will not support them and that baby boomers are not saving enough for retirement. According to the increase in 401 (k) and Keogh retirement plans, the ongoing stock market on Wall Street, and t
41、he likelihood of large inheritances, there is evidence that baby boomers will reach age 65 with greater fi nancial assets than previous generations.The Hudson Institute advocates reforming government policies that now discourage work and savings, especially for older workers. Among the reports recom
42、mendations Tax half of all Social Security benefits, regardless of other income; provide 80/oo larger benefits for each year beyond 65; and permit workers nearing retirement to negotiate com pensation packages that may include a lower salary but with greater healthcare benefits. However, it may take
43、 real and fruitful planning to find the right solution to the early retirement of older experienced workers; any measures taken must be allowed to pro long the serviceability of older experienced workers.（分数：5.00）(1).According to Hudson Institute researchers, the effect of the early retirement of qu
44、alified workers on the U. S. economy is_.（分数：1.00）A.constructiveB.significantC.inconclusiveD.detrimental(2).The older experienced workers in America tend to retire early because their pro longed service may_.（分数：1.00）A.do harm to younger generationsB.end up with few or no benefitsC.give play to thei
45、r potentialsD.shed light on social trends(3).The second paragraph is written chiefly to show that_.（分数：1.00）A.there will be an acute labor shortage in the near futureB.baby-boomers contribute much to the US economic outputC.government policies concerning older people are out-datedD.older workers are
46、 enthusiastic about collecting social benefits(4).When mentioning “ the ongoing stock market on Wall Street“, the writer_.（分数：1.00）A.is calling attention to the privileges to which baby-boomers are entitledB.is calling for the government to take countermeasures against labor shortageC.is refuting a
47、notion about experienced workers early retirementD.is justifying the ineffectiveness of federal tax and benefit policies(5).Towards the issue, what the writer is most concerned about will be_.（分数：1.00）A.to advocate radically reforming government policiesB.to take into account the benefits upon retir
48、ementC.to put in practice what Hudson researchers believe inD.to prolong the practicability of older experienced employees4The history of responses to the work of the artist Sandro Botticelli (14441510) sug gests that widespread appreciation by critics is a relatively recent phenomenon. Writing in 1
49、550, Vasari expressed an unease with Botticellis work, admitting that the artist fitted awkwardly into his evolutionary scheme of the history of art. Over the next two centuries, academic art historians defamed Botticelli in favor of his fellow Florentine, Michelange lo. Even when anti-academic art historians of the early nineteenth century rejected many of the standards of evaluation adopted by their predecessors, Botticellis work remained out side of accepted taste, pleasing neither amateur observers n
