单选题Happiness can be described as a positive mood and a pleasant state of mind. According to recent investigations, sixty to seventy percent of Americans consider themselves to be moderately happy, one in twenty persons feel very happy. Psychologists have been studying the factors contributing to happiness. It is not predictable nor is a person in an apparently ideal situation necessarily happy. The ideal situation may have little to do with his actual feelings. A good education and income are usually considered necessary for happiness. Though both may contribute, they are only chief factors if the person is seriously under-educated or actually suffering from lack of physical needs. The rich are not likely to be happier than the middle-income group or even those with very low incomes. People with college education are somewhat happier than those who didn"t graduate from high schools, and it is believed that this is mainly because they have more opportunity to control their lives. Yet people with a very high income and a college education may be less happy than those with the same income and no college education. It should be noted that people quickly get used to what they have, they are happiest when they feel they are increasing their level, no matter where it stands at a "given time. The best formula for happiness is to be able to develop the ability to tolerate frustration, to have a personal involvement and commitment, and to develop self-confidence and self-esteem.

单选题 Scholastic thinkers held a wide variety of doctrines in both philosophy and theology, the study of religion. What gives unity to the whole Scholastic movement, the academic practice in Europe from the 9th to the 17th centuries, are the common aims, attitudes, and methods generally accepted by all its members. The chief concern of the Scholastics was not to discover new facts but to integrate the knowledge already acquired separately by Greek reasoning and Christian revelation. This concern is one of the most characteristic differences between Scholasticism and modern thought since the Renaissance. The basic aim of the Scholastics determined certain common attitudes, the most important of which was their conviction of the fundamental harmony between reason and revelation. The Scholastics maintained that because the same God was the source of both types of knowledge and truth was one of his chief attributes, he could not contradict himself in these two ways of speaking. Any apparent opposition between revelation and reason could be traced either to an incorrect use of reason or to an inaccurate interpretation of the words of revelation. Because the Scholastics believed that revelation was the direct teaching of God, it possessed for them a higher degree of truth and certainty than did natural reason. In apparent conflicts between religious faith and philosophic reasoning, faith was thus always the supreme arbiter; the theologians' decision overruled that of the philosopher. After the early 13th century, Scholastic thought emphasized more the independence of philosophy within its own domain. Nonetheless, throughout the Scholastic period, philosophy was called the servant of theology, not only because the truth of philosophy was subordinated to that of theology, but also because the theologian used philosophy to understand and explain revelation. This attitude of Scholasticism stands in sharp contrast to the so-called double-truth theory of the Spanish-Arab philosopher and physician Averroes. His theory assumed that truth was accessible to both philosophy and Islamic theology but that only philosophy could attain it perfectly. The so-called truths of theology served, hence, as imperfect imaginative expressions for the common people of the authentic truth accessible only to philosophy. Averroes maintained that philosophic truth could even contradict, at least verbally, the teachings of Islamic theology. As a result of their belief in the harmony between faith and reason, the Scholastics attempted to determine the precise scope and competence of each of these faculties. Many early Scholastics, such as the Italian ecclesiastic and philosopher St. Anselm, did not clearly distinguish the two and were overconfident that reason could prove certain doctrines of revelation. Later, at the height of the mature period of Scholasticism, the Italian theologian and philosopher St. Thomas Aquinas worked out a balance between reason and revelation.

单选题Most consumers in China"s cities would rather "suffer silently" over grievances than stand up for their rights, a survey showed Friday. A two-week poll conducted showed that about 70 percent were only partly familiar with the law bolstering (支持) protection of consumers" rights and interests implemented two years ago. Twenty percent said they had heard over the ages in a number of quite peculiar forms but did not know the content, and the remaining 10 percent knew nothing about the law at all. Those consumers surveyed lost on average 25.85 yuan a month in 1995 due to shoddy quality, fake goods, and other problems. More significant was people"s meekness (逆来顺受) in accepting bad service without complaining. More than 60 percent of those surveyed said they would rather suffer silently rather than stand up for their rights. This was particularly the case among the elderly and people with higher levels of education. Those consumers said that they rather sustained an occasional loss than paid the transportation fares necessary to pick up invoice (发票) and find a quality inspection department for an appraisal. They added: "Even if you go to court and win the case, the best decision you"ll receive will be returning double the amount lost. " So the situation of consumer protection in China needs improvement.

单选题The world's population continues to grow. There now are about 4 billion of us on the earth. That could reach 6 billion by the end of the century and 11 billion in another 75 years. Experts long have been concerned about such growth. Where will we find the food, water, jobs, houses, schools and health care for all these people? A major new study shows that the situation may be changing. A large and rapid drop in the world's birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations. Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy. More women are going to school or working at jobs away from their homes instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population growth. China is one of the nations that has made great progress in reducing its population growth. China has already cut its rate of population growth by about one half since 1970. China now urges each family to have no more than one child. And it hopes to reach zero population growth, the number of births equaling the number of deaths, by the year 2000. Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people.

单选题Do you forget to turn off the lights and heaters when you go out of a room? In 2040 it will not matter. They will turn themselves off—and on again when you return. You will choose the temperature for each room, the lighting and the humidity. A sensor will detect the presence of a human (and, with luck, ignore the dog! ) and turn the systems on, and when the humans leave it will turn them off again. The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will detect faulty electrical appliances, plugs or switches, isolate them so that they cannot harm anyone, and then warn you that they need repair. They will detect fire and if you are out of the house, the computer will call the fire brigade. It will also call the police should the sensors detect an intruder. This will not be too difficult because the locks on the outside doors will be electronic. You will open them using your personal card—the one you use for shopping—maybe using a number known only to you. It will be impossible to lose the key, and a housebreaker will have to tamper (拨弄) with the lock or with a window. It is not very difficult to make such tampering send a signal to the computer. The computer will be more than a fireman policeman servant. It will be an entertainer, and most of your entertainment will come right into your home. It does now, of course, but by 2040 "entertainment" will mean much more. For one thing, you will be able to take part actively, rather than just watching...
