单选题Only moments after announcing a policy of zero tolerance on cellphone(手机) use in the classroom, Ali Nazemi heard a ring. Nazemi, a business professor at Roanoke College in Virginia, took out a hammer and walked towards a young man. He smashed the offending device. Students' faces turned white all over the classroom. This episode reflects a growing challenge for American college teachers in, as the New York Times puts it, a "New Class (room) War: Teacher vs. Technology". Fortunately, the smashed-phone incident had been planned ahead of time to demonstrate teachers' anger at inattentive students distracted by high-tech devices. At age 55, Nazemi stands on the far shore of a new sort of generational divide between teacher and student. The divide separates those who want to use technology to grow smarter from those who want to use it to get dumber. Perhaps there's a nicer way to put it. "The baby boomers seem to see technology as information and communication," said Michael Bugeja, the author of Interpersonal Divide: the Search for Community in a Technological Age. "Their children seem to see the same devices as entertainment and socializing." Bugeja's online survey of several hundred students found that a majority had used their cell phones, sent or read e-mail, and logged onto social-network sites during class time. A quarter of the respondents admitted they were taking the survey while sitting in a different class. The Canadian company Smart Technologies makes and sells a program called SynchronEyes. It allows a classroom teacher to monitor every student's computer activity and to freeze it at a click. Last year, the company sold more than 10,000 licenses. The biggest problem, said Nancy Knowlton, the company's chief executive officer, is staying ahead of students trying to crack the program's code. "There's an active discussion on the Web, and we're monitoring it." Knowlton said. "They keep us on our toes./

单选题In America Mother"s Day is celebrated on the second Sunday in May. On that day we send our mothers a special Mother"s Day card, and perhaps some flowers or candy, to show our love and appreciation for all they have done for us. Although Mother"s Day is a relatively new holiday in America, more and more other countries are also setting aside a day to honor their mothers. I want to tell you today how the idea of having a special day for mothers began. It all started over a hundred years ago with a woman named Anna May Jarvis. Anna was born on May 1, 1864, just before the end of the Civil War and the assassination of President Lincoln. She was the daughter of a "minister", which in American English means a church leader. She was a quiet gift who liked to study in school, and she liked everyone and was liked by everyone as well. After she became an adult, Anna worked for a life insurance company in Philadelphia, Pennsylvania—a city about halfway between New York City and Washington, D.C.. Then, in 1906, just two weeks after Anna"s 42nd birthday, her mother died. It was the second Sunday in May. In the months that followed, Anna began to change. No longer was she so gentle, so relaxed and easy-going. Instead she now had just one goal for her life—to have her mother and all other mothers honored throughout the whole world on the second Sunday of May. After more than a year of careful planning, Anna arranged the first Mother"s Day church service, on May 10, 1908, in Grafton, West Virginia. The next year Anna was able to get the city of Philadelphia, where she lived and worked, to proclaim the second Sunday of May as an official Mother"s Day—the first city to do so. After three more years, the state of West Virginia, where Anna"s mother had lived, made Mother"s Day a statewide observance—not a holiday in the normal sense, but still a day to remember what mothers have done for their children and society.

单选题Traditionally, universities have carried out two main activities: research and teaching. Many experts would argue that both these activities play a critical role in serving the community. The fundamental question, however, is how does the community want or need to be served? In recent years universities have been coming under increasing pressure from both the governments and the public to ensure that they do not remain "ivory towers(象牙塔)" of study separated from the realities of everyday life. University teachers have been encouraged, and in some cases constrained (强迫), to provide more courses which produce graduates with the technical skills required for the commercial use. If Aristotle wanted to work in a university in the UK today, he would have a good chance of teaching computer science but would not be so readily employable as a philosopher. A post-industrial society requires large numbers of computer programmers, engineers, managers and technicians to maintain and develop its economic growth but "man", as the Bible says, "does not live by bread alone." Apart from requiring medical and social services, which do not directly contribute to economic growth, the society should also value and enjoy literature, music and the arts. Because they can also promote economic growth. A successful musical play, for instance, can contribute as much to the Gross National Product through tourist dollars as any other things.

单选题The advantages and disadvantages of a large population have long been a subject of discussion among economists (经济学家). It has been argued that the supply of good land is limited. To feed a large population, inferior land must be cultivated and the good land worked intensively. Thus, each person produces less and this means a lower average income than could be obtained with a smaller population. Other economists have argued that a large population gives more scope for specialization and the development of facilities such as ports, roads and railways, which are not likely to be built unless there is a big demand to justify them. One of the difficulties in carrying out a world-wide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In the developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, it will be the first concern of government to place a limit on the birthrate, whatever the consequences may be. In the highly industrialized society, the problem may be more complex. A decreasing birth rate may lead to unemployment because it results in a declining market for manufactured goods. When the pressure of population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.
