单选题I am writing this at home because last week my ergonomic(符合人体工程学的)chair at the office fell apart, unable any longer to bear my weight. I am writing it on a computer that is propped on top of two thick books, because otherwise my neck would be cricked as I peered down at the screen. At 1. 93m and weighing... well, I'm not going to say what I weigh, but think second-row rugby union forward...I am not built for this world. We therefore welcome a new report from Professor Tim Hatton at the University of Essex, demonstrating that the average height of men in Europe has increased by 4 inches in the past century and in the UK by a whopping 5 inches. A similar increase is likely to have occurred among women, but, because the study is based in part on military records, evidence is thinner on the ground. The problem, as Hatton observes, is that the world hasn't kept pace with our increased height. I long ago abandoned buses—levering myself into a narrow seat was impossible. Air travel is also challenging. I was in the back row of an easyJet plane recently, which has even less space than an ordinary seat, and would have ended up with severe backache had it not been for some thoughtful passenger not turning up, allowing me to relocate to an aisle seat where the only danger is being hit by the trolley. Small cars are impossible—I have to drive with my head through the sunroof. West End theatres are hopelessly cramped. As before in cricket grounds: I would under no circumstances pay ￡80 for a plastic bucket seat at a Test match, where I would be wedged uneasily between two loud, red-trousered merchant bankers sipping warm champagne. As for those appalling pine beds with footboards, usually found in absurdly small hotel rooms where I invariably get stuck in the toilet because the door won't open with me inside, they should be banned immediately. Our extra height generally means extra weight. US data shows baseball players are on average 3 inches taller and 2 stones heavier than they were a century ago—and these are the super-fit guys. Other data suggests ordinary Americans have added 2. 54 cm and 12. 6 kg in the past 50 years alone. We are all giants now—or will be soon. As a representative of this new breed, I would say just one thing: beware garden furniture. It appears to be made for gnomes. I routinely remove pleasant-looking but wholly impractical cane chairs, and once, while interviewing the actress Jenny Seagrove, snapped the strings of a hammock-type chair in her garden. It is not easy to get your interviewee to take you seriously after your vast bulk has been plunged suddenly onto their manicured lawn.

单选题{{B}}Passage One{{/B}} For more than 40 years, Earth has been sending out distress signals. At first they were subtle, like the thin shells of bald-eagle eggs that cracked because they were laced (使混合) with DDT. Then the signs were unmistakable, like the covering of smoke over the Amazon rain forest, where farmers and ranchers (牧场主人) set fire to clear land. Finally, as the new millennium drew near, it was obvious that Earth's pain had become humanity's pain. The collapse of the North Atlantic cod (鳕鱼) fishery put 30,000 Canadians out of work and ruined the economies of 700 communities. In 1998, deforestation worsened China's floods, which killed 3,600 people and left 14 million homeless. Population pressures and overcrowding raised the toll from 1999's rains in Latin America, which killed more than 30,000 people and created armies of environmental refugees. And how have we responded to four decades of ever louder distress signals? We've staged a procession, of Earth Days, formed Green parties, passed environmental laws, forged a few international treaties and organized global gabfests (杂谈会) like the 1992 Earth Summit in Rio de Janeiro. All the while, the decline of earth's ecosystems has continued unabated. What will it take for us to get serious about saving our environment? When will environmentalism more from being a philosophy promoted by a passionate minority to a way of life that governs mainstream behavior and policy? How can we understand that Earth is one big natural system and that torching tropical rain forests and destroying coral reefs (珊瑚礁) will eventually threaten the well-being of towns and cities everywhere? One crucial step is a true accounting of the state of the planet, a thorough assessment of the health of all Earth's major ecosystems, from oceans to forests. Only a comprehensive global survey can show how damage to one system is affecting other systems and can determine whether Earth as a whole is losing its ability to nurture the full diversity of life and the economies of nations.

单选题Famed singer Stevie Wonder can't see his fans dancing at his concerts. He can't see the hands of his audience as they applaud wildly at the end of his Superstition. Blind from birth, Wonder has waited his whole life for a chance to see. Recently, Wonder visited Mark Hamayan, a vision specialist. He thought that a new device currently being studied by Humayan might offer him that chance. The device, a retinal prosthesis, is a tiny computer chip implanted inside a patient's eye. The chip sends images to the brain and allows some sightless people to see shapes and colors. Wonder hoped the retinal prosthesis might work for him. "I've always said that if ever there's possibility of my seeing," said Wonder, "then I would take the challenge." Unfortunately for Wonder, that challenge will have to wait. Humayan explained that the device isn't ready for people who have been blind since birth. Their brains may not be able to handle signals from a retinal prosthesis because their brains have never handled signals from a healthy eye. The retinal prosthesis and other devices, however, show great promise in helping many other sightless people who once had vision see again. Perhaps one day soon, some formerly sightless people may be in Wonder's audience looking up—and seeing him—for the very first time. Wonder's willingness to take part in retinal prosthesis studies and the results of those studies are giving new hope to people who thought they would be blind for the rest of their lives. More than one million people in the United States are considered legally blind, meaning that their eyesight is severely impaired. Another one million are totally blind. Two types of specialized cells in the retina—rods and cones—are critical for proper vision. Light enters the eye and falls on the rods and cones in the retina. Those cells convert the light to electrical signals which travel through the optic nerve to the brain. The brain interprets those signals as visual images. Rods detect light at low levels of illumination. For instance, rods allow you to see faint shadows in dim moonlight. Cones, on the other hand, are most sensitive to color. Some diseases can damage cells in the retina. For instance, macular degeneration causes blindness and other vision problems in 700,000 people in the United States each year. The condition is caused by a lack of adequate blood supply to the central part of the retina. Without blood, the rods, cones, and other cells in the retina die. Devices such as the retinal prostheses won't prevent or cure our eye diseases, but they may help patients who have eye disorders regain some of their vision. Different forms of retinal prostheses are currently being developed. On one type, a tiny computer chip is embedded in the eye. The chip has a grid of about 2,500 light-sensing elements called pixels. Light entering the eye strikes the pixels, which convert the light into electrical signals. The pixels then send the electrical signals to nerve cells behind the retina. Those cells send signals via the optic nerve to the brain for interpretation. Many people who have had a retinal prosthesis implanted say they can see shapes, colors, and movements that they couldn't see before. "It was great," said Harold Churchey, who received his retinal prosthesis 15 years after he became totally blind. "To see light after so long—it was just wonderful. It was just like switching a light on." (572 words. Current Science. April 7, 2000)

单选题 D．H. Lawrence was the fourth child of Arthur Lawrence and Lydia Beardsall, and their first to have been born in Eastwood. Ever since their marriage in 1875, the couple had been on the move. Arthur's job as a miner had taken them where the best-paid work had been during the boom years of the 1870s, and they had lived in a succession of small and recently built grimy colliery villages all over Nottinghamshire. But when they moved to Eastwood in 1883, it was to a place where they would remain for the rest of their lives;the move seems to have marked a watershed in their early history. For one thing, they were settling down. Arthur Lawrence would work at Brinsley colliery until he retired in 1909. For another, they now had three small children and Lydia may have wanted to give them the kind of continuity in schooling they had never previously had. It was also the case that, when they came to Eastwood, they took a house with a shop window, and Lydia ran a small clothes shop. presumably to supplement their income, but also perhaps because she felt she could do it in addition to raising their children. It seems possible that, getting on badly with her husband as she did, she imagined that further children were out of the question. Taking on the shop may have marked her own bid for independence. Arthur's parents lived less than a mile away, down in Brinsley, while his youngest brother Waiter lived only 100 yards away from them in another company house, in Princes Street. When the family moved to Eastwood, Arthur Lawrence was coming back to his own family's center: one of the reasons, for sure, why they stayed there. Lydia Lawrence probably felt, on the other hand, more as if she were digging in for a siege. Eastwood may have been home to Arthur Lawrence, but to Lydia it was just another grimy colliery village which she never liked very much and where she never felt either much at home or properly accepted. Her Kent accent doubtless made Midlands people feel that she put on airs.
