单选题 Bruce remained ______ for several hours after the car accident.

单选题 Human needs seem endless. They might be regarded as making up several levels. When there is enough money to satisfy one level of needs, another level appears: The first and most basic level of needs involves food. Once this level is satisfied, the second level of needs, clothing and some sort of shelter, appears. By the end of World War Ⅱ, these needs were satisfied for a great majority of Americans. Then a third level appeared. It included such items as automobiles and new houses. By 1957 or 1958 this third level of needs was fairly well satisfied. Then, in the late 1950s, a fourth level of needs appeared: the 'life-enriching' level. While the other levels involve physical satisfaction, that is, the feeding, comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and happiness. It includes a variety of goods and services. Among them are vacation trips, the best medical and dental care, and recreation. Also included here are fancy goods and the latest styles in clothing. On the fourth level, a lot of money is spent on services, while on the first three levels more is spent on goods. A fifth level would probably involve needs that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice. After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels.

单选题 After Man has dreamed about flying for a long time. Michael Moshier is a dreamer. He invented the Solo Trek. The Solo Trek had a 120 horsepower engine with twin fans. Only one person flies. As you fly above the roofs, you lean a little forward. You can see everything under you. You are flying like Superman. Michael Moshier looked at the jet belt and the rocket belt that was developed 20-30 years ago. Nothing ever came from them. People still can't fly. Inventors have tried to make it easy for people to fly. Paul Moller has been working on his flying car for 30 years. He now says it is ready for tests. It would take off and land vertically, go 600 miles an hour, and deliver 20 miles to the gallon. A computer would do the actual flying. He says it could be sold next year for about a million dollars. NASA is working with Moshier to help develop his flying machine. The first users are likely to be military. It's been 50-years since Robert Fulton invented his airphibian, a flying car. It flew, and is now in the Smithsonian Museum. Getting dreams to fly is never easy.

单选题 It is possible that the weather of the world may be changing. Some scientists imagine that this could even mean the beginning of another ice age. The effects of such a change in weather on human population of the world would be frightening. Recent research suggests that the warming trend(倾向)of the past hundred years or so may be coming to an end. During the past ten years, scientists tell us that the temperature of the world has dropped a little. This would have effects on wind and rain in the weather picture. Scientists believe clouds may be an important factor (因素) in changing the amount of heat on the earth. Another possibility is that man's agriculture and industry ways may affect the natural weather.

单选题 Anyone who has ever attended a university knows that the quality of lecturers varies greatly. A few are very effective communicators, conveying the substance of their lectures clearly and interestingly and inspiring students to want to know more about the subject. Others produce dull lectures from which the students learn little and which are likely to kill any interest they may have in the subject. Lecturing is a major part of a university lecturer's job and it would seem reasonable that effectiveness in this task should be a major standard in assessing a lecturer for promotion. However, it is very often the case that far more weight is given to such factors as participation in research, number of publications and even performance of administrative duties. My point of view is that a lecturer's lecturing should be regularly evaluated and that the best people to carry out this evaluation are those directly on the receiving end. It could, of course, be argued that students are not competent to evaluate the academic quality of lectures, If anyone should evaluate lecturers, it should be their colleagues. However, I am not arguing that students should be asked to comment on the academic content of lectures, but to evaluate the effectiveness. I suspect that many of the objections to student evaluation stem from the fear some lecturers have of being subject to criticism by their students. However, lecturers should see such evaluation as an opportunity to become aware of defects in their lecturing techniques and thus to become better lecturers. Such a system should benefit both students and lecturers as well as help department heads to assess the strengths and weaknesses of their teaching staff.

单选题 First, the spotted owl was threatened by logging in the Pacific Northwest. Now it’s in danger from a new enemy, the barred owl. Barred owls have been moving to the Northwest from the eastern part of the United States. Stan Sovem has studied spotted owls. Now when he calls for spotted owls, barred owls are starting to appear. Sovem threw a mouse on the ground, and a barred owl grabbed it. Scientists have learned that spotted owls start to vanish when barred owls come. Some barred and spotted owls have mated and produced hybrid babies. One spotted owl was killed by a barred owl. Professor Ned K. Brown of the University of California-Berkeley says, 'In some areas of Washington, the barred owls moved into very dense, deep woods. The same kind of woods that are opened up, or destroyed by logging, that adversely influences the spotted owls.' Ten years have passed since the federal government began protecting the spotted owl. Loggers were forced to limit logging on seven million acres of government land. No one is sure how the arrival of the barred owls will impact laws that protect spotted laws. The barred owls like to live in the deep forests where loggers like to cut down trees. The barred owls will likely keep migrating to the Northwest.

单选题 Copernicus was born in Torun, Poland, on February 19, 1473. Little is known about his early life except that his father died when he was 10. An uncle adopted (收养) him, his two sisters, and his brother. The uncle saw to it that the two boys received a good education. Copernicus went to the University of Cracow. There he studied such subjects as Latin, mathematics, and astronomy, It was probably at that time that he changed his Polish name, Niklas Koppernigk, to the Latin form of Nicolaus Copernicus. In 1496 Copernicus went to Italy, where he spent the next 10 years studying at various universities. In Copernicus'time people still believed that all things-the sun, the stars, and the planets-moved around the earth. It was an old belief that few men had ever questioned. Aristotle had based his theory of astronomy on this belief. Because the Chruch had long been the center of learning, the theory was also linked to religious (宗教的) beliefs. In 1506 Copernicus returned to his homeland. A few years later he began to work for the Church. All those years Copernicus carried on his work in astronomy. He had just the most basic equipment and, like other scientists of his day, made observations with only his eyes. Still, using mathematics and logic (逻辑), Copernicus worked out a different theory, which held that the planets went around the sun. Copernicus did not announce his ideas. He did not want to make trouble. But he could not hid the scientific truth. So he talked about his theory with his friends, who strongly advised him to have his work published. His great book, On the Revolutions of the Heavenly Bodies, appeared at the very end of his life. Copernicus saw the first copy on the day he died, May 24, 1543.
