The right rests on the assumption that open and free inquiry within a teacher's or researcher's field of study is essential to the pursuit of knowledge and to the performance of his or her proper educational function. At present this right is observed generally in countries inwhich education is regarded as a means not only of pouring in established views but also of enlarging the existing body of knowledge. The concept of academic freedom implies also that a teacher's employment depends primarily on the competence of teachers in their fields rather than on irrelevant considerations such as political or religious beliefs or attachments.The concept and practice of academic freedom, as recognized presently in Western civilization, date roughly from the 17th century. Before the 17th century, intellectual activities at universities were restricted largely by theological considerations, and opinions or conclusions that conflicted with religious doctrines were likely to be condemned as heretical. In the late 17th century the work of such men as the English philosophers John Locke and Thomas Hobbes helped pave the way for academic freedom in the modern sense. Their writings demonstrated the need for unlimited inquiry in the sciences and for a general approach to learning unrestrained by preconceptions of any kind. In the 18th and 19th centuries, universities in Western Europe and the United States enjoyed increasing academic freedom as acceptance of the experimental methods of the sciences became more widespread and as control of institutions by religious denominations became less rigorous. In Britain, however, religious tests for graduation, fellowships, and teaching positions were not abolished until the late 19th century.During the second half of the 20th century academic freedom was recognized broadly in most Western countries. However, violations of the right increased as dictatorship emerged in various countries, notably in Germany, Italy, and Russia. Educators in Italy were forced to pledge support to the Fascist regime. Similar restrictions, including the teaching of racist theories in some fields, were enforced in German universities under National Socialism. Violations of academic freedom also occurred in the United States in the 20th century. A notable example was the Scopes trial, held in Dayton, Tennessee, in 1925. A high school teacher was accused and convicted of violating a state law that forbade the teaching of the theory of evolution in the public schools. This legislation was abolished in 1967.In the early 1950s, largely because of congressional investigations of communism in the U. S., many institutions of higher learning adopted regulations requiring loyalty oaths from university teachers. Some of these oaths, insofar as they were required only of teachers, were declared unconstitutional in some state courts. All professional associations of teachers and administrators, including the National Education Association, the American Association of Colleges, and the American Association of University Professors, are opposed to special loyalty oaths and to all violations of academic freedom. The 1960s and early 1970s were marked by protest and violence on college campuses over United States involvement in the war in Vietnam. In some places professors were dismissed or arrested for protesting American participation in the war. This turmoil reached a tragic climax in 1970 with the killing of several students during campus demonstrations. In the long run, however, these disturbances led to a broad recognition of the legitimate concerns of students about the quality of higher education, and of the responsibility of universities, rather than the public or the government, to maintain essential academic order.By 1973, when U. S. troops were withdrawn from Vietnam, a general growth in higher education was under way. Significant increase in enrollments and expansion of faculties, as well as a broadening of the makeup of both student and faculty populations, contributed to a vast enrichment of the academic curriculum, to increasing faculty control over the content of programs, and, overall, to the enhancement of the freedom to teach and to learn in colleges and universities.Beginning in the early 1970s in the United States(and somewhat later in other countries such as Canada and the United Kingdom, however, institutions of higher education were faced with serious financial problems which also harmed academic freedom. For example, the rise in irregular faculty appointments, intended to save money, created a virtual underclass of teachers lacking the employment security generally considered necessary for the exercise of academic freedom.Threats to and violations of academic freedom continued in the 1980s. The U. S. government, in the name of national security, imposed severe restraints on the publication of research results. The influence of resurgent religious conservatism was felt in some areas in effort to introduce religious teachings in elementary and secondary schools, and in limits on free expression at church-affiliated colleges and universities.21.

Linda has never met the children, but that’s all part of the joy of giving as secret Santas, she says."It's an amazing feeling to buy gifts on an anonymous (匿名的) basis," says Linda. "It brings a whole new meaning to the holidays."Linda and Tony are an American couple living in Toronto, Canada, and Linda did charitable work as a member of the American Women's Club of Toront o. As the name suggests, members are U.S. citizens living in Toronto, who join together for fellowship and community service.To find her "adopted" family, Linda goes to the local schools and requests a wish list for a family that's struggling to survive. Last year she helped a single mother with three children. The mother works as a cleaning lady in a nursing home."The list is always heartbreaking. They have an opportunity to ask for anything and do just the opposite, asking for basic clothes or simple toys," she says. "We always buy the kids a new winter coat, hats, and gloves." She also buys gifts for the parents.Last year Linda asked the mother for a second wish list--one that didn't include the basics. "Every child should have a Christmas that sticks with them for a lifetime." She purchased iPods for the two older children and a video game system for the youngest. "I have learned a very valuable lesson in all of this," says Linda. "Pay attention to what's going on in your own backyard--no matter where you live."The joy of giving as secret Santas is much sweeter when the gift is anonymous.52.

Read the following passages and do the questions below: (30%)Passage OneThe first year of college is the most difficult year. For students who leave their hometown to attend college, one of the hardest parts of starting college is that freshmen have to learn to rely on themselves. They must be able to live in small, crowded rooms and take care of their own things, learn to use a university library, and find their way around town. They should be able to follow schedules, organize their time for study and play, and think for themselves.Before arriving on campus, a new student gets a packet of information from the university. This packet usually includes a campus map, information about places to live and have meals, and general information about campus life. The packet does not however, tell students how to get along with others or how to be successful at studies.A freshman usually has an advisor –a professor who helps the student plan his school work. Together they check course offerings, examination schedules, and university requirements before the semester starts. Freshmen need to take courses in number of areas, so such advice is important. Most freshmen take a language course, mathematics, and composition of history. The advisor gives advice as to which courses the new student should take.The social side of life is another. If the student lives on campus, for example, there will be many other new students to talk with. There will also be after-class activities to help new students to get to know one another and make friends.By the end of the semester, most students start to feel both confident and comfortable at school. The next hard part is going back home for the semester break. Most freshmen suddenly feel that they don’t fit in at home anymore. It’s not easy to be afreshman at university.41.

My husband had insisted on watering the flowers in the garden by himself, and when he discovered that he couldn’t manage he had asked me for help at the last moment. So now we had an hour to get to the airport. Luckily, there were not many cars or buses on the road and we were able to get there just in time. We checked in and went straight to a big hall to wait for our flight to be called. We waited and waited but no announcement was made. We asked for informatio n and the girl there t old us that the plane hadn’t even arrived yet. In the end there was another announcement telling us that passengers waiting for Flight LJ108 could get a free meal voucher(凭单) and that the plane hadn’t left Spain for technical problem s. We thought that meant that it wasn’t safe for the plane to fly. We waited again for a long time until late evening when we were asked to report again. This time we were given free vouchers to spend the night in a nearby hotel.The next morning after a bad night because of all the planes taking off and landing, we reported back to the airport.

The parrot is an unusual bird that can be taught to talk, can be easily cared for, and can give a lively feeling anywhere. With the help of an experienced parrot owner, a parrot can develop a large vocabulary. In addition, a parrot can be trained to say ―Pretty boy‖ or ―See you tomorrow‖, and it also can learn to whistle (吹口哨) or sing. No matter what an owner decides to teach a bird, training a parrot takes much patience, but the reward is a stream of chatter. Another reason for the parrot’s popularity is thatthis pet does not require much care. For example, even aspoiled parrot does not need a house sitter for the purpose of daily walks and daily feeding. In fact, a parrot owner may leave his or her pet with enough food for five days and have no fear that the parrot will eat too much. Still another advantage of owning a parrot is its inexpensive food, including nuts, corn, and grain—along with an apple, or banana. Perhaps the most likely reason the parrot is becoming such a well-liked pet is that it is a combination of tameness and wildness. Because the parrot can live in almost any environment, it makes a fine, tame friend for many people. In addition, because it can be easily trained, it is a delightful performer. At the same time, its colorful feathers give it an air of the strangeness of parrots’ native home, the thick forests. Thus, the parrot, once a highly valued gift presented to kings and noble families, is now appreciated(欣赏,理解) by a growing number of people.51. The word ―pet‖ most probably means ______.A. small duckB. small rabbitC. lovely birdD. lovely chicken52. Which of the following is NOT a reason for the easy raising of the parrot?A. It eats very little.B. Its food is inexpensive.C. It does not need a house sitter.D. It does not require daily walks as dogs do.53.

The writer ______.A. likes the parrotB. dislikes the parrotC. does not like any petD. values the parrot highly55. The main idea of the passage is that ______.A. everybody likes parrotsB. parrots are easy to raiseC. parrots are not expensiveD. we should train parrot patientlyIV.
