单选题The North American frontier changed some of the characteristics of the pioneers of the 1750' s and intensified others. They were, as a group, semiliterate, proud, and stubborn, as dogged in their insistence on their own way of life as pine roots cracking granite ( 花岗岩) to grow. Perhaps their greatest resource was their capacity to endure. They outlasted recurrent ( 周期性发生的) plagues of smallpox (天花) and malaria (痢疾) and a steady progression of natural accidents. They were incredibly prolific. Squire Boone' s family of eight children was small by frontier standards. James Roberston, an eventful neighbor of Boone' s and the frontier of Nashville, had eleven children. Twice-married, John Sevier, the first governor of Tennessee, fathered eighteen; his long time enemy, John Tipton, also twice married, produced seventeen. The entire assets of one of these huge families often amounted, in the beginning, to little more than an axe, a hunting knife, an auger, a rifle, a horse or two, some cattle and a few pigs, a sack of seed corn and another of salt, perhaps a crosscut saw, and a loom. Those who moved first into a new region lived for months at a time on wild meat, Indian maize, and native fruits in season. Yet if they were poor at the beginning, they confidently expected that soon they would be rich. In a way almost impossible to define to urban dwellers, a slice of ground suitable for farming represented not just dollars and cents, but dignity. The obsession brought shiploads of yearners (渴求者) every week to Boston, New York, Philadelphia, Baltimore, Charles Towne, and Savannah. It sent them streaming westward into the wilderness after their predecessors to raise still more children who wanted still more land.

单选题At the European Commission in Brussels, they have a joke about the work interpreters do—Languages", they say, "have nothing to do with interpretation, it helps to know them. "Anyone thinking of becoming an interpreter would bear this so well in mind. Translating languages, especially in a political context, involves far more than mere linguistic ability. To work in an international organization, such as the United Nations, you need to be approved by one of the various international translators or 'interpreters' associations. To achieve this, you must experience rigorous and lengthy training, either at an accrediting organization's own school, or on a postgraduate course at university. But a qualification in languages is not the only route into the job. At London's University of Westminster, candidates get offered a place on the interpreter's course if they can show that they have "lived a bit", in the words of one lecture. Young people who have just left university often lack adequate experience of life. The University also looks for candidates who have lived for long time in the countries where their acquired languages are spoken. They are also expected to have wide cultural interests and a good knowledge of current affairs. This broad range of interests are essential in a job which can re- quire interpreting discussions of disarmament(裁军) on Monday, international fishing rights on Tues- day, multinational finance on Wednesday, and the building and construction industry on Thursday. Interpreters also rely on adrenaline(肾上腺素)—which is caused by the stress and challenges of the job—to keep them going through their demanding schedules. Many admit that they enjoy the buzz of adrenaline they get from the job, and it's known that their heart rates speed up while they are working. It's also a job With its own risks and excitement. Interpreters are needed in war zones as well as in centers of international diplomacy, like the U.N.

单选题A pioneering study by Donald Appleyard made the surprising discovery that a sudden increase in the volume of traffic through an area affects people in the way that a sudden increase in crime does. Appleyard observed this by finding three blocks of houses in San Francisco that looked much alike and had the same kind of middle-class and working-class residents, with approximately the same ethic mix. The difference was that only 2000 cars a day ran down Octavia Street (LIGHT street in Appleyard's terminology) while Gough Street (MEDIUM street) had 8 000 cars a day and Franklin Street (HEAVY street) had around 16 000 cars a day. Franklin Street often had as many cars in an hour as Octavia Street had in a day. Heavy traffic brought with it danger, noise, fumes, and soot, directly, and trash secondarily. That is, the cars didn't bring in much trash, but when trash accumulated, residents seldom picked it up. The cars, Appleyard determined, reduced the amount of territory residents felt responsible for. Noise was a constant intrusion into their homes. Many Franklin Street residents covered their doors and windows and spent most of their time in the rear of their houses. Most families with children had already left. Conditions on Octavia Street were much different. Residents picked up trash. They sat on their front steps and chatted with neighbors. They had three times as many friends and twice as many acquaintances as the people on Franklin. On Cough Street, residents said that the old feeling of community was disappearing as traffic increased. People were becoming more and more preoccupied with their own lives. A number of families had recently moved. And more were considering it. Those who were staying expressed deep regret at the destruction of their community.

单选题One afternoon when lessons were over, Peter and Paul left school. When the boys reached home, it was seven o' clock. It was dark outside, but there was a light inside their home and the door was open. They knew their parents were both at work, so they were surprised to see a man inside. They could see the man was looking for something. "He must be a thief," Paul said. "I'll report to the police and you try to talk to him. Then Peter went inside while Paul quickly hurried off to telephone the police. When the man saw Peter, he looked frightened. Then he smiled and said, "You don't know me, but I'm your father's friend, he asked me to fetch (取) some money for him." In no time two policemen arrived. As soon as the man saw the policemen, he tried to run off. But he was stopped and caught by the policemen. Just then the boy's parents returned. "Is this man your friend?" one of the policemen asked the boy's parents. "No!" said Peter's father. "He is a thief. He wanted to steal my money. I'm glad you've caught him./
