Section A 26 When Louise Brown was born on 25 July 1978, she kicked off an era. The first “test tube baby“ is a mother herself now, and shes been joined by millions of others born

16、 with the【 C1】 _of in vitro fertilization(体外受精 ), or IVF. Now specialists wonder whether people who were conceived by IVF are likely to be【 C2】 _. “By and large, the kids are just fine. Its not like the kids having【 C3】 _arms or heads,“ says Carmen Sapienza, a scientist at Temple University. But non

17、e is older than their early 30s, and the vast【 C4】 _are under the age of 20, so they havent had time for long-term health problems to show up. One source of worry is that so many IVF babies have low birth weight. Children-conceived through IVF are more likely to【 C5】 _less than 2.5 kilograms than ar

18、e babies conceived【 C6】 _. That could spell trouble ahead, because low-birth-weight babies often have long-term health problems. Theyre more likely to be obese, to have diabetes(糖尿病 )or other problems. With that in mind, Sapienza and colleagues have looked at genes that are likely to play a role in

19、such health problems. They found that certain DNA-patterns, which affect how genes are【 C7】 _, are different between IVF and non-IVF children. Theres no way to tell if thats because of the【 C8】 _used to produce the IVF babies or whether the difference has something to do with the underlying infertil

But it does suggest that children conceived by IVF are【 C10】 _on some level. A)weigh E)unclear I)unique M)majority B)technology F)naturally J)healthy N)minority C)help G)expr

ALong before the president swore last year that America will “have the highest propo

22、rtion of college graduates in the world“ by 2020, the importance placed on going to college was firmly rooted in the American soul. The case is compelling: As good jobs increasingly require more education, college is widely seen as the ticket to personal economic security and to global competitivene

23、ss. And yet, theres a potential trend of concern about a group of students sometimes called “the forgotten half,“ who, for whatever reason, do not think college is for them. Its expressed by soul-searching parents such as Crave, whose son doesnt thrive in the classroom. Its also expressed increasing

24、ly by educators, economists and policy analysts, who question whether its realistic and responsible to push students into college even if the odds of academic success seem low. BTheyre swimming against a powerful tide. A small but growing number of states now require all high-schoolers to take a col

25、lege entrance exam. Philadelphias mayor opened an office in City Hall last month to help residents get information about how to attain a college degree. Bill Gates, perhaps the worlds most famous college dropout, has poured more than $2 billion into programs and scholarships to help more students co

26、mplete college. But whats still getting lost, some argue, is that too many students are going to college not because they want to, but because they think they have to. “Were force-feeding them“ the idea that “you must go to college or youll be a second-class citizen,“ says Marty Nemko, a California

27、career counselor. Economic benefits, and more CThe debate over college is not new, but todays economic climate has raised the stakes. “Theres beginning to be a lot of concern among the American public thatif you dont get into that upper class, youre going to struggle your whole life,“ says Public Ag

28、endas Jean Johnson. A four-year degree is no guarantee of wealthy of course. About 25% of those with bachelors degrees earn less than those with two-year degrees, studies by Georgetown Universitys Center on Education and the Workforce have found. But research consistently has shown that, on average,

29、 those at the top of higher educations pecking order reap the most benefits, both economically and beyond. D“This is a market for social position, which is why we spend so much on going to Harvard and one of the reasons its hard to get a student excited“ about community college, says Anthony Carneva

30、le, director of the center. “Class is real, and it has consequences. The position you hold, where you work, really determines your status.“ Falling through the cracks EEconomists continue to debate the slight differences of trend data for jobs and wages. But some argue that college dropout rates alo

31、ne suggest many students are wasting their time and money. Federal data show that fewer than 60% of new students graduate from four-year colleges in six years, and just one in three community college students earn a degree. “Its fine for most kids to go to college, of course, but it is not obvious t

32、o me that that is the best option for the majority,“ says Mike Gould, founder of New Futures, a Washington, D.C.-based organization that provides scholarships for low-income students pursuing anything from a four-year degree to a massage-therapy certification. “Some education may be a good thing or

33、it may just be a lot of debt.“ FThe problem, Gould and others say, is that many high schools focus so much on college that low-achieving students fall through the cracks. A Public Agenda report this month raises similar concerns about high school guidance counseling. It follows up on a December surv

34、ey that concluded most young workers who dont have a college degree “are in their jobs by chance, not by choice,“ and that guidance toward a career path “is hardly clear and purposeful.“ The apprentice(学徒 )model GApprenticeships have long been popular in Europe, but workforce-oriented high school tr

35、aining is not nearly as common in U.S. schools. One reason is that such programs sound dangerously similar to tracking sorting students by ability level, a practice repeatedly rejected in U.S. culture, in which the dominant philosophy is that all students should have opportunity to meet their full p

36、otential. If high schools were to advise students that some education beyond high school is not necessary for everyone, “theres a little bit of a concern that. were saying a lesser goal is OK for the populations of students who have been historically least well-served by higher education,“ says Jane

37、 Wellman, executive director of Delta Project, which studies higher education spending. HIn recent years, male college-going and completion rates have raised concerns. But those least well-served historically are low-income and underrepresented minority students, who are less likely than their peers

38、 to pursue two- and four-year degrees, and most at risk of not completing college if they do enroll. ISome evidence suggests, though, that students already are being held to different standards. A recent national survey of high school teachers by ACT Inc., the educational testing company, found 71%

39、agreed “completely“ or “a great deal“ that high school graduates need the same set of skills and knowledge whether they plan to go to college or enter the workforce, yet 42% said teachers reduce academic expectations for students they perceive as not being college-bound. Studies released in November

40、 by Deloitte, an international consulting firm, suggest another disconnect: A survey of 400 low-income parents found that 89% say its “extremely“ or “very important“ that their child goes to college, but just 9% of high school teachers viewed preparing students for college as their most important mi

41、ssion. JDeloitte CEO Barry Salzberg, chairman of the College Summit, which seeks to increase college enrollment rates, says thats misguided. “I think we should measure high schools on their college entrance rate and figure out a way to track performance of high school graduates in college and see ho

42、w many go beyond one full year of college.“ But others say the enthusiasm to increase college-going rates ignores the reality that many students will be in over their heads once they start college. “College preparation for everyone is a very nice ideal, but we have a very high failure rate,“ says No

43、rthwestern University professor James Rosenbaum. “If we dont start letting counselors be frank, were not going to fix this system.“ 37 High college dropout rate indicates that some students are wasting their time and money in college. 38 Historically speaking, minority students, being poor and under

44、represented, are the least well-served group in college education. 39 Some are worried that the high college failure rates will be ignored if we put too much emphasis on increasing college-going rates. 40 The apprenticeship in the U.S. is not as popular as in Europe in that the model conflicts with

45、the U.S. dominant culture. 41 To increase college graduation rate, the mayor of Philadelphia informed residents about how to get a college degree. 42 College education is always considered as the ticket to economic security and high competitive power. 43 Teachers will lower their academic expectatio

46、ns of those who are considered as not being college-bound. 44 The studies by Georgetown Universitys Center on Education and the Workforce show a bachelors degree doesnt necessarily bring high wages. 45 Many students think they have to go to college because thats the way to the upper social position.

47、 46 According to the survey in December, those who dont have a college degree are in theirs jobs by chance. Section C 46 Its hot now in Afghanistan, where 35% of the population is under-fed. But soon it will be cold, and many of the countrys roads will become inaccessible because of snow and landsli

48、des, making it difficult to get food to market. Knowing these things gets Stacy McCoy out of bed every morning and out into the countryside, visiting Afghani women and farmers to offer new agricultural techniques and hardier seeds. She also works to improve their marketing skills so that they can be

49、 exposed to new ways to sell goods in the marketplace. The marketing efforts have helped organize the women and farmers into teams so that they have more food to offer collectively and can work more closely together to share their knowledge. McCoy is one of many American scientists who have devoted their careers to international development in the name of making the world a better place. “It can be hard living away from family and that is a choice sometimes goin
