About 50 years ago the idea of disabled people doing sports was never heard of. But when the annual games for the disabled were started at Stroke Mandeville, England in 1948 by Sir Ludwig Guttmann, the situation began to change. Sir Ludwig Guttmann, who had been driven to England in 1939 from Nazi Germany, had been asked by the British government to set up an injuries centre at Stroke Mandeville Hospital near London. His ideas about treating injuries included sports for the disabled.In the first games just two teams of injured soldiers took part. The next year, 1949, five teams took part. From those beginnings things developed fast. Teams now come from abroad to Stroke Mandeville every year. In 1960 the first Olympics for the Disabled were held in Rome. Now, every four years the Olympic Games for the Disabled are held, if possible, in the same place as die normal Olympic Games, although they are organized separately. In other years Games for the Disabled are still held at Stroke Mandeville. In the 1984 wheelchair Olympic Games, 1, 604 wheelchair athletes from about 40 countries took part. Unfortunately, they were held at Stroke Mandeville and not in Los Angeles, along with the other Olympics.The Games have been a great success in promoting international friendship and understanding, and in proving that being disabled does not mean you can't enjoy sports. One small source of disappointment for those who organize and take part in the games, however, has been the unwillingness of the International Olympic Committee to include the disabled events at the Olympic Games for the able bodies. Perhaps a few more years are still needed to convince those fortunate enough not to be disabled that their disabled fellow athletes should not be excluded.The first games for the disabled were held________after Sir Ludwing Guttmann arrived in England.A．50 yearsB．21 yearsC．9 yearsD．4 years
The Building of the PyramidsThe oldest stone buildings in the world are the pyramids.【46】 There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids. The most famous of these are the "Step" pyramid and the "Bent" pyramid.Some of the pyramids still look much the same as they must have done when they were built thousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stone to use in modem buildings.【47】. These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last for ever. 【48】. However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves.【49】. Nevertheless, by examining the actual pyramids and various tools which have been found, archaeologists have formed a fairly cleat picture of them.One thing is certain: there must have been months of careful planning before they could begin to build.【50】 You may think this would have been easy with miles and miles of empty desert around, but a pyramid could not be built just anywhere. Certain rules had to be followed, and certain problems had to be overcome.A. The dry climate of Egypt has helped to preserve the pyramids, and their very shape have made them less likely to fall into ruin.B. It is practically certain that plans were made for the building of the pyramid because the plans of other large works have fortunately been preserved.C. The first thing they had to do was to choose a suitable place.D. Consequently, we are only able to guess at the methods used.E. Many people were killed while building the pyramids.F. They have stood for nearly 5,000 years, and it seems likely that they will continue to stand for thousands of years yet.(46)

He wanted to be a pilot and after some months he managed to get to the air force training school, where they taught pilots to fly'.There, the first thing that new students had to do was to be taken up in a plane by an experienced pi lot, to give them some ideas what it felt like. Even those who had traveled as passengers in commercial (商业的 ) airline planes before found it strange to be in the cockpit (驾驶舱)of a small fighter plane, and most of the students felt nervous.The officer who had to take the students up for their first flight allowed them to fly the plane for a few seconds if' they wanted to and if they were not too frightened to try, but be was always ready to take over as soon as the plane started to do dangerous things.George was one of those who took over the controls of the plane when he went up in it for the first time, and after the officer had taken them [Yom him again. George thought that he had better ask a few questions to show how interested he was and how much he wanted to learn to fly. There were a number of instruments (仪表) in front of him, so he chose one and asked the officer what it was. The officer looked at him strangely for a moment and then answered, "That is the clock."44.

共用题干第三篇 The Body ThievesIn the early nineteenth century in Britain,many improvements were being made in the world of medicine.Doctors and surgeons were becoming more knowledgeable about thehuman body.Illnesses that had been fatal a few years before were now curable.However, surgeons had one problem.They needed dead bodies to cut up,or dissect（解剖）.This was the only way that they could learn about the flesh and bones inside the body,and the only way to teach new surgeons to carry out operations.The job of finding these dead bodies was carried out by an unpleasant group of people called "body snatchers". They went into graveyards（墓地）at night and, using woodenshovels to make less noise,dug up any recently buried bodies.Then they took the bodies to the medical schools and sold them.A body could be sold for between ￡5 and ￡10, which was a lot of money at that time.The doctors who paid the body snatchers had an agreement with them一they never asked any questions.They did not desire to know where the bodies came from,as long as they kept arriving.The most famous of these body snatchers were two men from Edinburgh called William Burke and Wil!iam Hare.Burke and Hare were different because they did not」ust dig up bodies from graveyards.They got greedy and thought of an easier way to find bodies. Instead of digging them up,they killed the poorer guests in Hare's small hotel.Dr Knox, the respected surgeon they worked for,never asked why all the bodies they brought him had been strangled（勒死）.For many years Burke and Hare were not caught because,unsurprisingly,the bodies of their victims were never found by the police.They were eventually arrested and put ontrial in 1829.The judge showed mercy to Hare and he was released but Burke was found guilty and his punishment was to be hanged.Appropriately,his body was given to the medical school and he ended up on the dissecting table,just like his victims.In one small way，justice was done.Now,over 1 50 years later,surgeons do not need the help of criminals to learn their skills.However,the science of surgery could not have developed without their rather gruesome（令人毛骨惊然的）help.The bodies of Burke's and Hare's victims couldn't be found by the police becauseA: they had been stolen.B:they had been strangled.C: they had been dissected.D:they had been buried.

问答题Practice 3 Science, in practice, depends far less on the experiments it prepares than on the preparedness of the minds of the men who watch the experiments. Sir Isaac Newton supposedly discovered gravity through the fall of an apple. Apples had been falling in many places for centuries and thousands of people had seen them fall. But Newton for years had been curious about the cause of the orbital motion of the moon and planets. What kept them in place? Why didn’t they fall out of the sky? The fact that the apple fell down toward the earth and not up into the tree answered the question he had been asking himself about those larger fruits of the heavens, the moon and the planets.
问答题Water Crisis in Spain There’ve been floods, gales and heat waves across Europe-and some lay the blame for the unpredictable weather on climate change. Spain is undergoing its worst drought for sixty years with many areas in the south of the country not seeing a drop of rain for months. Some reservoirs are nearly empty while the volume of water in some rivers is down to a third of its normal level. Guadalajara, in the centre of the country, used to be a prosperous tourist area. Its old Moorish name, ironically, means water running through rocks. But when Emma Jane Kirby visited the small town of Buendia, she found an ecological disaster area in the marketing. There’s a strange smell around the lake at Buendia, the sort of smell that greets you when you first open the fridge after a week or two away from home—a putrid stench of salad leaves that’ve begun to turn to compost in their cellophane bag. I’m reluctant to mention this to my companion, Marco ObisP0 because this after are is the place where he has spent every one of his summer holidays and a just few hours ago we were pouting over the family photograph books while he reminisced wistfully about his idyllic childhood. The problem is I don’t recognize this place as being the same one he showed me in the pictures Those images boasted bronzed children racing joyfully down a bank of emerald green grass towards a vast expanse of water so blue that the cornflower sky above looked dazzled. But this landscape is bleached and barren, the banks crusted white, the ponds patchy and the colour of thin ink. Guadalajara in the centre of Spain has been hit hard by drought. The rains haven’t come since spring last year, leaving the soil parched and lifeless, as cracked and scarred as the face of a small pox victim. The sun has sucked the life from anything that once had the energy to be green and stealthily, its hot tongue has lapped away at the lake’s edge reducing the reservoirs to a fifth of the size they were twenty years ago. As quickly as the water’s evaporated, so have the tourists—the holidaymakers from all over Europe with whom Marco played as a child have been lured away to other areas of Spain where swimming or sailing a boat can be done without fear of scraping knees or hulls on the lake bed. If the landscape is crying out for new water management, then it’s weeping with painful dust-dry tears. North east of Buendia, only the ancient Spanish pine forests seem able to sustain life, some atavistic survival instinct wing them triumph over droughts which long ago killed off the weaker competition. But the trees are now so dehydrated and sapless they’ve become irresistible to fire-two weeks ago, thirteen thousand hectares were lost to a spark from a barbecue-an inferno that also claimed the lives of eleven men. As far as the eye can see now, the hills are almost bare.
问答题Practice 2Transformation of St Kilda Seventy-five years ago, the residents of a group of islands off the northwest coast of Scotland packed up and left for good. Their home—St Kilda—now has World Heritage status but with the departure of the St Kildans in August 1930, a way of life that had existed for thousands of years, vanished. St Kilda was years for years known as the most remote settlement in the entire British Empire, but actually it is not so far away—around 200 km west of the nearest point of the Scottish mainland. Seventy-five years ago, at the end of August 1930, the last 36 islanders banked up their turf fires, opened their Bibles at Exodus, put some oats on the table, then left forever, bringing to an end a habitation and a way of life that stretched back at least two thousand years. St Kilda is an archipelago of sea stacks, skerries and four islands, of which only one, Hirta, was permanently inhabited. It was remote in ways other than geography. The people, who never numbered more than a couple of hundred, spoke not English but a distinctive form of Gaelic. Their economy, their whole culture, revolved round seabirds—fulmars, gannets and puffins. They ate them and exchanged their feathers and precious oil for goods such as tea and sugar from the mainland. In the Victorian era, at the height of Britain’s imperial adventure, this self-sufficient life held a strange fascination. St Kilda became a fashionable tourist destination and steamers regularly dropped anchor in Village Bay. But the visitors could not comprehend the St Kildans they gawped at. There is an astonishing recording in the BBC’s archives of an islander saying that her mother, in payment for a bale of tweed which had taken all winter to weave, was given an orange. She didn’t know what it was. There had been worse traumas: St Kilda’s graveyard is one of the most heartrending places. It is full of tiny hummocks, where infants are buried. Newborn babies were all anointed where the cord had been cut with a concoction of fulmar oil, dung and earth and 8 out of 10 of them died of neonatal tetanus. The minister finally put a stop to this in 1891 and after that the babies lived, but it was too late. Add to this grief, emigration and harsh religion and it’s no wonder that the St Kildans lost heart. By the 1920s there were no longer enough people to do all the work. In 1930 they planted no crops and petitioned the government to take them off the island. St Kilda is now owned by the National Trust for Scotland. There are tow National Trust wardens and in the summer volunteer work parties come to maintain the buildings. There’s a resident archaeologist. A century on St Kilda has become a chic destination once again. There were 15,000 visitors last year. Recently one of the wardens found the first piece of litter; a plastic water bottle wedged between the stones of a wall.
