near。starvation diet prolongs the life of many animals Ronald Kahn at Harvard Medical School in Boston,US,and his colleagues have been able to extend the lifespan(寿命)of mice by 18 per cent by blocking the rodents(啮齿动物) increase of fat in specific cellsThis suggests that thinness-and hot necessarily diet-promotes long life in “ calerie (热量卡) restricted” animals “Its very cool work”says aging researcher Cynthia Kenyon of the University of California,San Francisco“These mice eat all they want,lose weight and live longerIts like heaven” Calorie restriction dramatically extends the lifespan of organisms as different as worms and rodentsWhether this works in humans is still unknown,partly because few people are willing to submit to such a strict diet But many researchers hope they will be able to trigger the same effect with a drug once they understand how less food leads to a longer lifeOne theory is that eating less reduces the increase of harmful things that can damage cellsBut Kahns team wondered whether the animals simply benefit by becoming thin To find out。they used biology tricks to disrupt the insulin(胰岛素)receptor(受体)gene in lab mice_but only in their fat cells“Since insulin is needed to help fat cells store fat,these animals were protected against becoming fat,”explains Kahn This slight genetic change in a single tissue had dramatic effectsBy three months of age,Kahn,s modified mice had up to 70 per cent less body fat than normal control mice,despite the fact that they ate 55per cent more food per gram of body weight In addition,their lifespan increasedThe average control mouse lived 753 days,while the thin rodents averaged a lifespan of 887 daysAfter three years,all the control mice had died,but one-quarter of the modified rodents were still alive “That they get these effects by just manipulating t11e fat cells is controversial,”says Leonard Guarente of the Massachusetts Institute of Technology, who studies calorie restriction and aging But Guarente says Kahn has yet to prove that the same effect is responsible for increased lifespan in calorierestricted animals“It might be the same effect or there might be two routes to long life,”he points out,“and that would be very interesting”Ronald Kahn and his colleagues can make mice live longer byAoffering them less foodBgiving them a balanced dietCdisrupting the specific genes in their fat cellsDpreventing them growing larger 2.Winners and Losers Why are the biggest winners in the past decade of trade globalization mostly in South and East Asia,whereas the biggest losers are mostly in theformer Soviet bloc(集团)andsubSaharan Africa History is a partial guide:East Asia has a long trading tradition,lately reinvigorated(给以新的活力)by the Chinese adoption of market economicsThe Soviet Union,on the other hand,was sheltered from freemarket forces for more than 70 yearsIn Africa,some countries are disadvantaged because of inadequate infrastructure(基础结构);many countries have little to trade but commodities,the prices of which have fallen in recent years In some regions,certain countries have suffered by adopting misguided policies,oftenunder pressure from International Monetary FundFirst among these is Russiawhich in theearly 1990s tried to embrace capitalism before first building the institutions that make capitalism work,such as an independent bank system,a system of business law, and all adequate method for collecting taxesEncouraged by the IMF the World Bank and the USDepartment of the Treasury, President Boris Yeltsins regime privatized the stateowned industrial sector, creating a class of oligarchs(寡头政治集团成员),who,knowing how unstable conditions were at homesent their money abroad instead of investing it at home In contrast,China,the biggest winner from globalization,did not follow the IMF formulaOf the former states of the Soviet bloc,only a few,notably Poland and Hungary, managed to grow, which they did by ignoring IMF advice and adopting expansionary plansincludingspending more than they collected in taxesBotswana and Uganda are also Success stories:despite their disadvantages,their countries achieved vigorous growth by creating stable civil societies,liberalizing trade and implementing reforms that ran counter to IMF prescriptionsAll African countries followed the IMF formulaARightBWrongCNot mentioned 3.Stanford University1 Stanford University, famous as one of northern Californias several institutions of higher learning,is sometimes called “the Harvard of the West” The closeness of Stanford to San Francisco,a city thirty-two miles to the north,gives the university a decidedly cosmopolitan (世界性的) flavor2 The students are enrolled mainly from the western United StatesBut most of the fifty states send students to Stanford,and many foreign students study here,as wellAnd standards for admission remain highYoung men and women are selected to enter the university from the upper fifteen percent of their high school classes3 Not only because of me high caliber(素质)of its students but also because of the desirablelocation and climate,Stanford has attracted to its faculty some of the worlds most respectedscholarsThe university staff has included many Nobel prize winners such as DrFelix Bloch,DrRobert Hofstadter, and DrWilliam Shockley in physicsDrAuthor Kornberg and DrJoshuaLederberg in medicineand DrPaul JFlory and DrLinus Pauling in chemistryThe Russiannovelist Aleksandr Solzhenistsyn has been in residenceStanfordS undergraduate school of engineering and its graduate schools of business,law,and medicine are especially well-regarded4 What is student life like on “The Farm” Culturallythe campus is a magnet for bothstudents and citizens of nearby communitiesP1ays,concerts,and operas are performed in the universitys several auditoriums and in its outdoor theater, where graduations are also heldSeveral film series are presented during the school yearGuest lecturers from public and academic life frequently appear on campusIn the evenings,many students gather to socialize in the Student Unions coffee house;here the beverages(饮料)and the atmosphere both have a decidedly European flavorFor the sportsminded,the Stanford campus offers highly developed athletic facilitiesTeam spots,swimming,and track and field activity are a11 very much part of the Stanford pictureSo are bicycling and jogging5 In addition to financial support from alumni(校友),Stanford receives grants from thegovernment and from private philanthropic(慈善的)foundations。In recent years,governmentgrants have made possible advanced studies in the fields of history, psychology, education,and atomic energyAt present Stanford is carrying out an ambitious building program,financed in part by山e Ford Foundations 25 million grantRecently added to the campus are a new physics building,new school of business,new graduate school of law,new student union,and undergraduate library23 Paragraph 2 _ .24 Paragraph 3_ . 25

Carpenters have known _(51)centuries that some woods are tougher than othersHickory(山核桃木),for example,was turned into axe handles and cartwheel spokes(轮辐)because it Can absorb shocks without breakingWhite oak,for example,is much more easilydamaged,_ (52)it is almost as denseJulian Vincent at Bathe University and his team were convinced the woods internal structure could explain the differencesMany trees have tubular(管的)vessels that run _ (53)the trunk and carry water to the leavesIn oak they are large,and arranged in narrow bands,but in hickory they are smaller,and more evenly distributedThe researchers _ (54)this layout might distribute a blows energy throughout the woodsoaking up a bigger hitTo test the idea,they drilled holes 0.65 millimetres across into a block of spruce(云杉),a wood with _ (55)vessels,and found that _ (56)withstood a harder knock_ (57)when there were more than about 30holes per square centimetre did the woods performance drop off A uniform substance doesnt cope well with knocks because only a small proportion of the material is actually _ (58)All the energy from the blow goes towards breaking thematerial in one or two places,but often the pieces left _ (59)are pristine(未经破坏的) But instead of the energy being concentrated in one place,the holes provide many weak spots that all absorb energy as they break,says Vincent“You are controlling the places_ (60)the wood breaks,and it can then absorb more _ (61),more safely”The researchers believe the principle could be applied to any material- _ (62)exampleto manufacture lighter and more protective packagingIt could _ (63)be used in Car bumpers,crash barriers and armour for military vehicles,says Ulrike Wegst, _ (64)the Max Plank Institute for Mental Research in StuttgartBut she emphasizes that you _ (65)to design the substance with the direction of force in mind“The direction ofloading is crucial,”she saysAinBsinceCforD at 6.27 Those high school graduates who can enter Stanford University _. 28 Many professors like to teach in this university partly because here_ . 29 On the faculty of the university there are_ . 30 Financial support from both private organizations and the government has made possible_ .
