单选题More than 6,000 children were expelled (开除) from US school last year for bringing guns and bombs to school, the US Department of Education said on May 8. The department gave a report to the expulsions (开除) as saying handguns accounted for 58 percent of the 6,093 expulsions in 1996 and 1997, against 7 percent for rifles (步枪) or shotguns and 35 percent for other types of firearms. "The report is a clear sign that out nation's public schools are cracking down (严惩) on students who bring guns to school," Education Secretary Richard Riley said in a statement. "We need to be tough-minded about keeping guns out of our schools and do everything to keep our children safe." In March 1997, an 11 years old boy and 13 years old boy using handguns and rifles shot dead four children and a teacher at a school in Jonesboro, Arkansas. In October, two were killed and seven wounded in a shooting at a Mississippi school. Two months later, a 14 years old boy killed three high school students and wounded five in Dasucah, Kentucky. Most of the expulsions, 56 percent, were from high school, which have students from about age 13.34 percent were from junior high schools and 9 percent were from elementary schools, the report said.

单选题2 For laymen ethnology is probably the most interesting of the biological sciences for the very reason that it concerns animals in their normal activities and therefore, if we wish, we can assess the possible dangers and advantages in our own behavioral roots. Ethnology also is interesting methodologically because it combines in new ways very scrupulous field observations with experimentations in laboratories. The field workers have had some handicaps in winning respect for themselves. For a long time they were considered as little better than amateur animal-watchers--certainly not scientists, since their facts were not gained by experimental procedures: they could not conform to the hard-and-fast ruie that a problem set up and solved by one scientist must be tested by other scientists, under identical conditions and reaching identical results. of course many situations in the lives of animals simply cannot be rehearsed and controlled in this way. The fall flocking of wild free birds can't be, or the homing of animals over long distances, or even details of spontaneous family relationships. Since these never can be re produced in a laboratory, are they then not worth knowing about? The ethnologists who choose field work have got themselves out of this impasse by greatly refining the techniques of observing. At the start of a project all the animals to be studied are live-trapped, marked individually, and released. Motion pictures, often in col or, provide permanent records of their subsequent activities. Recording of the animals' voices by electrical sound equipment is considered essential, and the most meticulous notes are kept of all that occurs. With this material other biologists, far from the scene, later can verify the reports. Moreover, two field observers often go out together, checking each other's observations right there in the field. Ethnology, the word, is derived from the Greek ethos, meaning the characteristic traits or features which distinguish a group--any particular group of people or, in biology, a group of animals such as a species. Ethnologists have the intention of studying "the whole sequence of acts which constitute an animai's behavior. " In abridged dictionaries ethnology is sometimes defined simply as "the objective study of animal behavior," and ethnologists do emphasize their wish to eliminate myths.

单选题Ann Curry is a famous news presenter of the NBC News "Today" show. When she was 15 she happened to walk into a bookstore in her hometown and began looking at the books on the shelves. The man behind the counter, Mac McCarley, asked if she'd like a job. She needed to start saving for college, so she said yes. Ann worked after school and during summer vacations, and the job helped pay for her first year of college. During college she would do many other jobs: she served coffee in the students' union, was a hotel maid and even made maps for the US Forest Service. But selling books was one of the most satisfying jobs. One day a woman came into the bookstore and asked Ann for books on cancer (癌症). The woman seemed anxious. Ann showed her practically everything they had and found other books they could order. The woman left the store less worried, and Ann has always remembered the pride she felt in having helped her customer. Years later, as a television reporter in Los Angeles, Ann heard about a child who was born with problems with his fingers and his hand. His family could not afford a surgical(外科的) operation, and the boy lived in shame, hiding his hand in his pocket all the time. Ann persuaded her boss to let her do the story. After the stray was broadcast, a doctor and a nurse called, offering to perform the surgical operation for free. Ann visited the boy in the recovery room after the operation. The first thing he did was to hold up his repaired hand and say, "Thank you. " What a sweet sense of satisfaction Ann Curry felt! At McCarley's bookstore, Ann always sensed she was working for the customers, not the store. Today it' s the same. NBC News pays her, but she feels as if she works for the people who watch the programmers, helping them make sense of the world.

单选题{{B}}Questions 16-20based on the following passage:{{/B}} After a 300 million yuan renovation project, Lidai Diwang Miao, or the Imperial Temple e f Emperors of Successive Dynasties, was reopened to the public last weekend. Originally constructed about 470 years ago, during the reign of Emperor Jiajing of the Ming Dynasty, the temple was used by emperors of both the Ming and Qing to offer sacrifices to their ancestors. It underwent two periods of renovation in the Qing Dynasty, during the reigns of emperors Yongzheng and Qianlong. From 1929 until early 2000, it was part of Beijing No. 159 Middle School. The temple's Jingdechongsheng Hall contains stone tablets memorializing 188 Chinese emperors. The jinzhuan bricks used to pave the floor, the same as those used in the Forbidden City, are finely textured and golden-yellow in color. According to Xi Wei, an official from the Xicheng District government present at the re-opening of the temple, jinzhuan bricks were made in Yuyao, Suzhou, specially for imperial use. The renovation was done strictly according to that carded out at the orders of Emperor Qianlong, and only those sections of the temple too damaged to repair have been replaced.

单选题Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world"s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis. But that doesn"t have to be the outcome. Water shortages do not have to trouble the world—if we start valuing water more than we have in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy.
