13、g allowing the development of social networks beyond thecommunity. have a need for communication, In rural (乡村 ) communities,re all social beings, we all researcher Paul Flatters technology such as cell phones and computers is limited, but expanding, thanks to groups like One Laptop Per Child, which
14、 supplies children in developing countries with basic laptops that allow them to research school projects and connect with others all over the world. Other groups, like theUK s Computer Aid, are helping rural villagers get wiredwith the help of portable cyber cafes ( 便携式网吧 ) that allowlocals to log

19、 come up with a list of organizations whose failures had done the most damage to the American economy (经济) in recent years, you would probably have to start withthe Wall Street firms that brought us the financial crisis ( 金融危机 ). From there, you might move on to the automakers inBut I would suggest
20、that the list should also include a less obvious nominee ( 被提名者 ): public education.At its top level, the American system of higher educationmay be the best in the world. Yet in terms of its main task turning teenagers into educated college graduates much ofthe system is failing.The United States do
21、es a good job enrolling ( 招 生 )teenagers in college, but only half of the students who enrollend up with a bachelor s degree.So finding out the causes of the college dropout crisis inthe world s largest economy matters greatly, and a newbook called “ Crossing the Finish Line tries t do preciselythat
22、. Its authors are economists William Bowen and Michael McPherson, and a doctoral candidate Matthew Chingos. Thefirst problem they discover is something they callunder-matching. It refers to students who choose not toattend the best college they can get into. They instead go to a less selective one,
23、perhaps one that is closer to home or less expensive. About half of the low-income students with a grade-point average of at least 3.5 in high school and an SATscore of at least 1,200 do not attend the best college theycould have. “ Ia really astonished by the degree to whichwell-qualified students
24、from poor families under-matched, said Mr. Bowen.In fact, well-off students attend the colleges that do thebest job of producing graduates. Meanwhile, lower-incomestudents even when they are better qualified often go tocolleges that excel (擅长 ) in producing drop- outs. “ It sreally a waste, Mr. Bowe
25、n said, “ and a big problem for thecountry. As the authors point out, the only way to lift thecollege graduation rate greatly is to lift it among poor and working-class students. Instead, it appears to have fallen.What can be done Money is clearly part of the answer.49. According to this text, which

29、y educationpossible solutionsDA new study has found that it may be possible to trainpeople to be more intelligent ( 聪 明 旳 ), increasing brainpower they had at birth.Until now, it has been widely supposed that the kind ofmental ability that allows us to solve new problems withouthaving any relevant (
30、相 关 旳 ) former experience whatpsychologists ( 心理学家 ) call fluid intelligence is innate andcannot be taught (though people can raise their grades on tests of it by practicing).But in the new study, researchers describe a method forimproving this skill ,along with experiments to prove it works.The key
31、, researchers found, was carefully structured training in working memory the kind that allowsmemorization of a telephone numberjust long enough to dial it. This type of memory is closely related to fluid intelligence, so the researchers reasoned that improving it might lead to improvements in fluid
32、intelligence.First they measured fluid intelligence ofvolunteers using standard tests. Then they trained each in a complicatedmemory task the child s card game,in which they had torecall a card they saw and heard. During the course, theyneeded to ignore irrelevant items, monitor ongoingperformance,
33、manage two tasks at the same time andconnect related items to one another in space and time. The four groups experienced a half-hour oftraining dailyfor 8, 12, 17 and 19 days, separately. To make sure they were The results, published Monday in The Proceedings of theNational Academy of Sciences , wer
34、e striking. Improvement inthe trained groups was a lot greater. Moreover , the longer they trained, the higher their scores were. All performers, from the weakest to the strongest , showed great improvement.“ Our results show you can increase your intelligence with proper training. said Dr Jaeggi, a
35、 co-author of the paper. “ No one knows how long the gains will last aftertraining stops, he added, “ and the experiment s designdid not allow the researchers to determine whether moretraining would continue to produce further gains. 53. The researchers thought the key to improving the intelligence
36、was _.A. memorizing telephone numbers B. improvingworking memory C. training in attention54. Which of the following intelligence a. ignoring irrelevantitemsc. making connectionsA. a, b, d. B. b, c, d.55. When the experimentb. monitoring ongoingperformanced. working in groupsC. a, c, d.was conducted,
37、 the _.A. trained the four groups for the same period oftimeB. trained the four groups at different time of the dayC. compared the four groups with control groupsD. trained the four groups together56. By writing the article, the writer wants to _.A. inform the readers of a new studyB. call on people
38、 to be trained to increase intelligenceC. tell people the improved intelligence will last foreverD. say the more one is trained, the more one s bornintelligence improvesEI don t everwant to talk about being a woman scientist again. There was a time in my life when people askedconstantly for stories
39、about what it s like to work in a fielddominated (主导) by men. I was never very good at telling holes.At 19, when I began studying astrophysics ( 天体物理学 ), it classroom. But while earning my Ph.D. at MIT and then aspost-doctor doing space research, the issue started to botherme. My every achievement j
40、obs, research papers, awards was viewed through the lens of gender ( 性别 ) politics. So immediately fight fiercelyThen one day a few years ago, out of my mouth came a that I didn t want to deal with gender issues. Why should curing sexism be yet another terrible burden on every femalescientist After
41、all, I don t study sociologyiiaplotlheory.Today I research and teach at Barnard, a women s college in New York City. Recently, someone asked me howmany ofthe 45 students in my class were women.
