单选题Most worthwhile careers require some kind of specialized training. Ideally, therefore, the choice of an 1 should be made even before choice of a curriculum in high school. Actually, 2 , most people make several job choices during their working lives, 3 because of economic and industrial changes and partly to improve 4 position. The "one perfect job" does not exist. Young people should 5 enter into a broad flexible training program that will 6 them for a field of work rather than for a single 7 . Unfortunately many young people have to make career plans 8 benefit of help from a competent vocational counselor or psychologist. Knowing 9 about the occupational world, or themselves for that matter, they choose their lifework on a hit-or-miss 10 . Some drift from job to job. Others 11 to work in which they are unhappy and for which they are not fitted. One common mistake is choosing an occupation for 12 real or imagined prestige. Too many high-school students—or their parents for them—choose the professional field, 13 both the relatively small proportion of workers in the professions and the extremely high educational and personal 14 . The imagined or real prestige of a profession or a "white-collar" job is 15 good reason for choosing it as life"s work. 16 , these occupations are not always well paid. Since a large proportion of jobs are in mechanical and manual work, the 17 of young people should give serious 18 to these fields. Before making an occupational choice, a person should have a general idea of what he wants 19 life and how hard he is willing to work to get it. Some want security; others are willing to take 20 for financial gain. Each occupational choice has its demands as well as its rewards.

单选题An Ohio State University study has linked behavior in young children 61 the type of job their mother has. Mothers with complex occupations that are self-directed and require working with other people 62 to have offspring with relatively low levels of behavior problems. The opposite held 63 when the jobs were routine, closely supervised, and dealt with things, rather than people. "A job that challenges and interests a mother and gives her an opportunity to exercise judgment and solve problems clearly has 64 consequences for her children's behavior," indicates 65 professor of sociology Elizabeth Mengaghan. Occupations with more positive conditions include management, sales, and teaching positions. Jobs that may be related to increased child behavior problems include book keeping, food service, and 66 line positions. Women who are supervised closely at work and made to 67 strict orders may be more likely to use this same style in 68 their kids. They may emphasize obedience to parental authority and the potential for 69 punishment. "We believe that the choice of such a parenting style may increase the 70 of behavior problems in children." On the 71 hand, mothers whose jobs are less controlled by supervisors and 72 must work closely with other people probably rely less on physical punishment, 73 encouraging children to think about consequences of their actions and 74 responsibility for their behavior. 75 an approach encourages youngsters to follow parental demands 76 they aren't being supervised because they have accepted parental values as their own. Moreover, mothers whose jobs don't 77 constant supervision" 78 problem-solving skills that they can bring to other parts of their life". The research also found that those who have 79 challenging and interesting jobs provide better home environments for their children. The mothers give their offspring more intellectual stimulation and emotional support, and this, 80 turn, is linked to fewer behavior problem.

单选题According to the latest report, consumer confidence ______ a breathtaking 15 points last month, to its lowest level in ten years.

单选题The American economic system is organized around a basically private-enterprise, market- oriented economy in which consumers largely determine what shall be produced by spending their money in the marketplace for those goods and services that they want most. Private businessmen, striving to make profits, produce these goods and services in competition with other businessmen; and the profit motive, operating under competitive pressures, largely determines how these goods and services are produced. Thus, in the American economic system it is the demand of individual consumers, coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes, that together determine what shall be produced and how resources are used to produce it. An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers. In the American economy, this mechanism is provided by a price system, a process in which prices rise and fall in response to relative demands of consumers and supplies offered by seller-producers. If the product is in short supply relative to the demand, the price will be bid up and some consumers will be eliminated from the market. If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to increase the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product. Thus, price is the regulating mechanism in the American economic system. The important factor in a private-enterprise economy is that individuals are allowed to own productive resources (private property), and they are permitted to hire labor, gain control over natural resources, and produce goods and services for sale at a profit. In the American economy, the concept of private property embraces not only the ownership of productive resources but also certain rights, including the right to determine the price of a product or to make a flee contract with another private individual.

单选题{{B}}Passage Two{{/B}} In the opinion of many Americans and Europeans, we only began to really explore our world in the sixteenth century. According to them, the sailors of the ancient world did not explore distant parts of the world; they did not have the necessary knowledge or skills for long sea journeys. However, the people who have this opinion are forgetting two important facts of history. First, sometimes early scientists have an idea which is correct, but scientists in later centuries do not believe it. For example, about 270 B. C., a Greek scientist had an idea which we all believe today: The earth moves around the sun. But for the following 1,600 years scientists did not believe this. In their opinion, the sun clearly moved around the earth. They discovered the truth again only in the fifteenth century! The second fact of history that many people forget is this: Ancient does not mean primitive. For example, the ancient Egyptians knew a great deal about the stars; they used this knowledge to find their way across the oceans. Two thousand years ago a Greek scientist who lived in Egypt calculated the distance around the earth. The results of his calculations were close to the real distance we know today! So the ancients had a great deal of scientific knowledge. They also had skills which equaled the skills of to- day. For example, 1,300 years ago and before, fishermen in Ireland built their boats of wood and leather. Today some fishermen in Ireland still make boats of the same de- sign. They use tools and materials which are not very different from the tools and materitals which their ancestors used. Why? The ancient design of the boats was good, and with skillful sailors, these boats can sail in all kinds of weather. Clearly long before the sixteenth century, people had the skill, the knowledge and the equipment which were necessary for long journeys by sea. The world did not have to wait until the sixteenth century for its first explorers!
