11、and a 2008 study from the Center for American Progress adds that increasing numbers of young voters and activists support traditionally liberal causes. But theres no easy way to see what those figures mean in real life. During the presidential campaign, Barack Obama assembled a racially and ideologi

12、cally diverse coalition with his message of hope and change; as the reality of life under a new administration settles in, some of those supporters might become disillusioned. As the nation moves further into the Obama presidency, will politically engaged young people continue to support the preside

13、nt and his agenda, or will they gradually drift away?The writers of Generation O (short for Obama), a new Newsweek blog that seeks to chronicle the lives of a group of young Obama supporters, want to answer that question. For the next three months, Michelle Kremer and 11 other Obama supporters, ages

14、 19 to 34, will blog about life across mainstream America, with one twist: by tying all of their ideas and experiences to the new president and his administration, the bloggers will try to start a conversation about what it means to be young and politically active in America today. Malena Amusa, a 2

15、t-year-old writer and dancer from St. Louis sees the project as a way to preserve history as it happens. Amusa, who is traveling to India this spring to finish a book, then to Senegal to teach English, has ongoing conversations with her friends about how the Obama presidency has changed their daily

The result could be a grou

18、p of young people that, like their boomer parents, grows up with a strong sense of purpose and sheds the image of apathy theyve inherited from Generation X (20 世纪 60 年代后期和 70 年代出生的美国人). Its no small challenge for a blog run by a group of ordinary if ambitious young people, but the members of Generat

24、 of Mechanical Engineering at Queen Mary College, London showed off his latest invention to the Press yesterday. It is a mechanical coal miner which, he claims, could solve Britains energy problems within ten years. Not that he thinks the National Coal Board will be at all interested. “I have taken

25、my previous ideas of mechanical mining to previous Chairmen of the Board but each time nothing has happened,“ he said. “The Board are not thinking enough about the future. My latest idea would put the cost of coal down and produce twice as much with the same labour force.“Professor Thring finished m

26、aking his mechanical coal miner only on Sunday night. He showed the wooden model yesterday at Queen Mary College. It is rather like a giant ant, with a headlight, two TV camera “eyes“, and arms the same size and strength as human arms.This particular coal miner, however, would only be eighteen inche

27、s tall, which would enable it to mine much smaller areas of coal than those that can be mined by human beings. It would open up rich areas of coal in the Durham coal fields which have not been workable since the last century.“I would have thought the unions would be delighted with the mechanical coa

28、l miners,“ said Professor Thring. “We would be employing as many miners as at present, with all their skills, but they would all be working on the surface.“The human miner would in fact sit at the controls above ground. He would put his .hands into “gloves“ and work the metal hands of the coal miner

29、 as if they were his own. The mechanical miner could go down as deep as 10,000 feet, and would cost 10,000.“It will put the cost of coal down because the cost of the machines is going to be very low in relation to the present cost of supplying fresh air to mines,“ said Professor Thring. “There need

30、to be no oxygen present, and this would mean there would be no risk of explosions.“The Professor does his economic sums as follows. Britain needs each year as much energy as 350 million tons of coal would provide; and North Sea oil will only provide the same amount of energy as 150 million tons of c

31、oal for fifty years, while the cost of nuclear power is ten times greater than the cost of getting oil.“We can get ten times as much coal as North Sea oil. We could have 250 million tons a yeardouble the present amountfor 200 years at least, and solve the energy crisis. The mechanical coal miner cou

32、ld be developed and active within six or seven years.“Could be, certainly! But Professor Thring knows very well how much luck he will need to succeed, which is why he gave the public display of his latest invention yesterday, to try to get opinion-makers on his side.（分数：5.00）(1).Professor Thrings me

A kind of machine which miners ride on.B. A machine to supply fresh air to tunnels.C. A digging mac

It does not have to go deep underground.B. It can work in very narrow spaces.C. It can work in the open air.D. It is twice as strong as a human

35、miner.（分数：1.00）A.B.C.D.(4).Why does Professor Thring think that the unions should be pleased about the mechanical coal miner?A. Because a lot more miners will be needed.B. Because miners will earn over 10,000 a year.C. Because miners will not have to work underground any more.D. Because it will redu

36、ce the risk of explosions.（分数：1.00）A.B.C.D.(5).Professor Thring expects that the Coal Board will _.A. reject his ideaB. listen to the PressC. be unable to develop his inventionD. reduce coal output（分数：1.00）A.B.C.D.十、Text 3(总题数：1，分数：5.00)A mystery over what caused the brightest supernova ever observe

37、d finally appears to have been solved. Two astronomers in the Netherlands say the explosion was the result of a cosmic pileup: dozens of massive stars crashing into each other, producing a monstrous heavyweight star that eventually exploded, leaving a giant black hole in its wake.Supernova 2006gy bu

38、rst into view in September 2006 in a distant galaxy, 240 million light years away. The blast was 100 times more powerful than a normal supernova, suggesting the exploding star weighed in at more than a hundred times the mass of the Sun.But astronomers found a puzzling detail in their observations: t

39、he supernova debris contained large amounts of hydrogen, which they would not have expected for such a massive star: It should have shed its outer hydrogen layers at an earlier stage.Although several possible explanations have been put forward to explain the massive blast including the formation of

40、a quark star and the production of huge quantities of antimatterno single theory could easily explain all of the observations.Now, in the journal Nature, Simon Portegies Zwart and Edward van den Heuvel of the University of Amsterdam say 2006gy may have been the result of a multiple-star collision in

41、 a dense stellar cluster.They say dozens of starssome of them hydrogen-richcollided to form a giant weighing in at over 100 Suns. Unable to support its own weight, the colossus blew itself to smithereens in an explosion that outshone its home galaxy.Computer simulations reveal that multiple collisio

42、ns are quite likely in very dense star clusters. Our own galaxy, the Milky Way, contains two such superdense clusters (the Arches cluster and the Quintuplet cluster), close to its centre. Indeed, supernova 2006gy also occurred close to the core of its host galaxy.If Portegies Zwart and van den Heuve

43、l are right, the dense cluster of stars should become visible once the supernova has faded sufficiently. This should happen a few years from now, they say.There may be another explanation for the brightness of the supernova, however. In the same issue of Nature, Stan Woosley of the University of Cal

44、ifornia at Santa Cruz and his colleagues show how multiple explosions in a single, very massive star could account for 2006gys behaviour.In this model, every explosion produces an expanding shell of material. When new ejecta catches up and collides with an older shell, so much energy is released tha

45、t the result will look like an over-luminous supernova.“One could, I suppose, make our massive star by merging smaller ones,“ Woosley said, “but that was not part of our model and does not seem necessary.“According to Woosleys calculations, the star may not yet have collapsed into a black hole. A ne

46、w explosion might happen in about 10 years or so, he says.（分数：5.00）(1).What phenomenon cannot the astronomers find a satisfactory explanation for?A. The supernova destroyed its hydrogen layers at an earlier stage.B. The supernova debris contained much hydrogen.C. The supernova resulted in a quark st

47、ar.D. The explosion of the supernova has produced very much antimatter.（分数：1.00）A.B.C.D.(2).Where are multiple-star collisions likely to happen?A. Near dense stellar clusters.B. In the Milky Way.C. Near the center of a galaxy.D. In the host galaxy.（分数：1.00）A.B.C.D.(3).How do Woosley and his team exp

48、lain the brightness of the supernova?A. It was caused by multiple explosions of a single massive star.B. It resulted from a multiple-star collision.C. It resulted from the merging of small stars.D. It was caused by the collision between expanding shells of material.（分数：1.00）A.B.C.D.(4).Which of the following statements about the black hole is NOT TRUE?A. Woosley predicts that a black hole may form in 10 years after another explosion.B. Woosley and his team have not yet observed a black hole.C. Zwart
