2、eres this great recurring Saturday Night Live skit from several years back where Phil Hartman plays an unfrozen caveman who goes to law school. He pontificates(发表武断的意见 )on the American judicial system while marveling at modem technology like The Tiny People in The Magic Box(a TV). It fits a common s
3、tereotype: Human ancestors were, well, cavemen, and not as smart as we are today. A new hypothesis from a Stanford geneticist tries to turn this stereotype upside down. (2)Human intelligence may have actually peaked before our ancient predecessors ever left Africa, Gerald Crabtree writes in two new
4、journal articles. Genetic mutations during the past several millennia are causing a decline in overall human intellectual and emotional fitness, he says. Evolutionary pressure no longer favors intellect, so the problem is getting worse. He is careful to say that this is taking quite a long time, so
5、its not like your grandparents are models of brilliance while your children will be cavemen rivaling Hartmans SNL character. But he does maintain that an ancient Athenian, plucked from 1000 BC, would be “among the brightest and most intellectually alive of our colleagues and companions. “ (3)His cen
6、tral thesis is that each generation produces deleterious(有害的 )mutations, so down the line of human history, our intelligence is ever more impaired compared to that of our predecessors. (4)Not surprisingly, the hypothesis, published in the journal Trends in Genetics, has several geneticists scratchin
7、g their heads. (5)“It takes thousands of genes to build a human brain, and mutations in any one of those can impair that process, thats absolutely true. Its also true that with each new generation, new mutations arise.but Crabtree ignores the other side of the equation, which is selection,“ said Kev
8、in Mitchell, associate professor at the Smurfit Institute of Genetics at Trinity College Dublin. “ Natural selection is incredibly powerful, and it definitely has the ability to weed out new mutations that significantly impair intellectual ability. There are various aspects in these papers that I th
9、ink are really just flunking about things in a wrong way. “ (6)Crabtree said he wanted to examine the cumulative effect of generation-to-generation mutation on intelligence, which is thought to be controlled by many genes. Using indexes that measure X-chromosome(染色体 )-related mental retardation, he
10、comes up with between 2,000 and 5,000 genes related to human intellectual ability. Using another index measuring average mutations that arise in each generation of children, he calculates that within 3, 000 years, “we have all sustained two or more mutations harmful to our intellectual or emotional
11、stability. “ (7)“There is a general feeling that evolution constantly improves us, but it only does that if there is selection applied,“ Crabtree said in an interview. “ In this case, it is questionable about how much selection is occurring now compared to the process of optimizing those genes, whic
12、h occurred in the jungles of Africa 500,000 years ago. “ (8)Theres already evidence for this in other areas, he argues: Take our sense of smell. Humans have far fewer olfactory receptors than other animals, he said were guided by our intellect now, not by smell. We can think about where a piece of f
13、ood came from, how it was processed, which plant its from, who has been around it, and so on. A dog, on the other hand, simply sniffs something and either eats it or doesnt. (9)Similarly, he believes evolution now selects for other traits namely, the most healthy and the most immune, not the most in
14、telligent. (10)But geneticists took issue with his claims, not to mention his citations and methods. Mitchell took issue with Crabtrees characterization of genes he describes them as links in a chain, with incredible overall disruptive power. Theyre like a bulb on a string of Christmas tree lights t
15、hat suddenly fails to work, taking out the entire strand with it: “It can be concluded that genes related to intelligence do not operate as a robust network, but rather as links in a chain, failure of any one of which leads to intellectual disability,“ he writes. Mitchell countered that this ignores
16、 other genes that dont cause intellectual disability. (11)“ Biological systems are robust to degradation of several different components,“ Mitchell said. “ Evolution has gone to a lot of trouble to craft your genome so its finely honed to do its job, and it doesnt make sense that you would have all
17、this random mutation in your brain cells. Also, you would have a very high rate of brain cancer. “ 1 According to the passage, “Saturday Night Live“ skit is a_. （ A） TV series with a playful spirit （ B） documentary on human ancestors （ C） talk show on exotic experiences （ D） radio program on modern
18、technology 2 Which of the following would Gerald Crabtree most likely DISAGREE with? （ A） Genetic mutations play a significant part in the decline of human intelligence. （ B） Harmful mutations tend to be unchangeable and easy to get rid of. （ C） Human beings today are no longer pressured to improve
19、their intellect. （ D） Natural selection is useful in the process of evolution only on some occasions. 3 Kevin Mitchell raises doubts about Gerald Crabtrees hypothesis in all of the following aspects EXCEPT its _. （ A） self-contradictory nature （ B） neglect of the power of natural selection （ C） rese
20、arch methodology and references （ D） characterization of genes 4 Which of the following would be the BEST title for the passage? （ A） A New Hypothesis Against a Common Stereotype. （ B） The Pros and Cons of Genetic Mutations. （ C） Human Intelligence Declined or Not? （ D） Evolution Process and Human I
21、ntellect. 4 (1)Social mobility in the U. K. could be reversed unless the government and universities make changes to encourage and pay for more students from disadvantaged backgrounds to take degrees, according to the governments independent adviser on the issue. Alan Milburn said in a report that s
22、ocial mobility was now “ flatlining at best“ after gains in the early part of the last decade. (2)“Given the headwinds that universities and higher education institutions are facing tuition fees, student caps, public funding constraints theres a real danger things will go backwards, rather than forw
23、ards,“ Milburn told The Guardian. “As the economy changes, who gets into university does become a very important driver of social mobility. “ (3)The report recommends changes across government policy and the way universities select, fund and encourage students from more disadvantaged areas, who he a
24、rgues have been shown to do better at university than pupils from private schools with the same grades. Suggestions include offering all students from poorer backgrounds an interview and considering offering places to those with lower grades. Acknowledging pressure on public spending during the rece
25、ssion, Milburn calls on all parties to commit to government funding for higher education rising from 1.2% currently to 1.5% , the average for the OECD group of advanced economies. (4)The former Labour MP and cabinet member, who was the first person in his family to go to university, said social mobi
26、lity created “fallers as well as risers“, echoing candid comments by the Liberal Democrat business secretary, Vince Cable, who told an audience on Wednesday that social mobility was often a “two-way street“ and “ a zero-sum game“. “ We want everyone to move up and no one to move down,“ said Cable. “
27、 But in the real world not everyone can be a star. Social mobility is often embodied in the comprehensive school pupil who reaches Oxbridge, but what about the school dropout who finished up in a lowly menial job? That is also social mobility. But this is surely what meritocracy is all about success
28、 through hard work, not through birth. “ (5)Milburns report says universities spend more than 400m to soften the impact of higher tuition fees on students from poorer backgrounds, but says there is little evidence that it is well spent, and calls for deep changes. It advocates that money is spent no
29、t just on reducing fees but helping to fund poorer students, and calls for a new version of the scrapped Educational Maintenance Allowance, intended to help poorer pupils remain in school to do A-levels. Universities are asked to agree to use “ contextual data“ when assessing applications to give pu
30、pils from worse schools a better chance, even if they have lower grades. Because some universities especially from the Russell Group of higher ranked institutions have objected to such a move in the past, Milburn offers them alternatives, including running new programmes to assess and prepare school
31、-leavers, such as summer schools, and guaranteeing interviews to pupils from schools in disadvantaged areas. (6)Ministers are urged to scrap a cap on student numbers, which Milburn calls an artificial limit on aspiration, and to better explain the tuition fees policy, under which students start repa
32、ying their loans when their earnings ripe above a certain threshold. One option would be to rename the policy a graduate tax, which it is “in all but name“, says Milburn, though he says it might be too late for that. He also calls for more funding for post-graduates, probably through upfront loans,
33、saying the issue is “in danger of becoming a social mobility timebomb“. (7)The proposal to re-introduce the EMA was widely welcomed by social and education organizations, including the childrens charity Barnados, which said it had evidence that children were having to choose between the cost of brea
34、kfast and their bus fare to school. The left-of-centre IPPR thinktank welcomed the reports suggestion that “we should look at applying the lessons of the pupil premium in schools to the university sector, with more funding being provided to institutions if they recruit from disadvantaged backgrounds
35、“ 5 According to Alan Milburns report, which of the following is the current situation of social mobility? （ A） It has been reversed. （ B） It hasnt any changes nowadays. （ C） It hasnt had any changes since the last decade. （ D） Government and universities pay for more students to take degrees. 6 Wha
36、t does the former Labour MP mean by saying “social mobility created fallers as well as risers “ in Para. 4? （ A） Social mobility is not a “two-way street“ and “a zero-sum game“. （ B） All students from comprehensive schools can enter Oxford by hard work. （ C） School dropouts always work with lower pa
37、yments. （ D） Social mobility is a mirror of constant efforts from different people. 7 Which of the following is INCORRECT according to Milburns report? （ A） Universities spend more money on softening the impact of higher tuition fees on poorer students. （ B） Money has already been spent not just on
38、reducing fees but helping to fund poorer students. （ C） Universities are asked to use superior standard when assessing applications. （ D） Some higher ranked universities do not refuse to change any more. 8 What is this passage mainly concerned? （ A） Education fund needs social mobility. （ B） Educati
39、on needs new policy and reform. （ C） Children pay more premiums in schools, so there are difficulties in their lives. （ D） Children were recruited from disadvantaged backgrounds, so they are very poor. 8 (1)Cambridge has taken the top spot in this years Guardian University Guide league table, breaki
40、ng its arch rival Oxfords six-year stint as the U. K. s leading institution. Oxford has come second and St Andrews third, while the London School of Economics has climbed four places from last year to take fourth place. University College London, Warwick, Lancaster, Durham, Loughborough and Imperial
41、 College make up the top 10. (2)Our analysis shows that universities with low rankings are almost as likely to be planning to charge maximum tuition fees of 9,000 in autumn 2012 as those with high rankings. London Metropolitan University, which comes bottom of The Guardian tables, intends to charge
42、between 4,500 and 9,000 for its degrees. Salford, Liverpool John Moores, Manchester Metropolitan and the University of East London all of which rank in the bottom 20 want to charge 9,000 for at least some of their courses. (3)The governments access watchdog, the Office for Fair Access, is looking at
43、 the fees each university in England wants to charge and will announce in July whether it approves. All the English universities in our top 20 intend to charge 9,000 fees, apart from London School of Economics, which has not yet decided. The first university that proposes to charge less than 9,000 f
44、or all of its courses is Sunderland, which is ranked 48th. There are a total of 120 institutions in the tables: 38 in the top half intend to charge 9,000 for at least some of their courses, while 18 in the bottom half propose to do the same. (4)Universities are ranked according to how much they spen
45、d per student: their student/staff ratio: the career prospects of their graduates: what grades applicants need: a value-added score that compares the academic achievements of first-years and their final degree results: and how content final-year students are with their courses, based on the annual N
46、ational Student Survey. Birmingham City University has fallen most since last year 24 places, from 66th to 90th while Middlesex is the biggest climber, reaching 75th place this year compared with 112th last year. Durham has risen from 17th place to eighth. While the oldest universities dominate the
47、top positions in the tables, the newest have improved their rankings since last year. Winchester has leapt from 96th place to 69th. (5)The tables, compiled by an independent consultancy firm, Intelligent Metrix, are weighted in favour of the National Student Survey. As part of the survey, final-year
48、 students are asked to score their universities for overall satisfaction, feedback and contact hours. Other league tables concentrate more on research ratings. The Guardian publishes an overall ranking table, separate tables to show which universities are best and worst for each subject and another
49、table for specialist institutions. The more a university spends on each student, the more likely it is to have a high ranking and the more satisfied its students seem. However, our judges took into account that some universities do not teach expensive courses, such as engineering, and so their spending is lower. (6)The tables show that Cambridge has overtaken Oxford in philosophy, law, politics, theology, maths, classics, anthropology and modern languages. However, Oxford overtook Cambridge in psychology and a
