单选题Text 3 Could the bad old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $26 a barrel, up from less than $10 last December. This near tripling of oil prices calls up scary memories of the 1973 oil shock, when prices quadrupled, and 1979—80, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time? The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short term. Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past. Rich economies are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP (in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that, if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25—0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980. On the other hand, oil—importing emerging economies—to which heavy industry has shifted—have become more energy—intensive, and so could be more seriously squeezed. One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand. A sizable portion of the world is only just emerging from economic decline. The Economist's commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70%, and in 1979 by almost 30%.

单选题Education begins with teachers. Yet teaching seems to be losing its appeal for many of the best and brightest college students. In high school, many of the best students decide that they want to be teachers, but their relatives and friends soon convince them to change their minds. One student's mother kept reminding her of the relatively skimpy salaries teachers currently earn until the student changed to another major. Another student took computer science courses because his father thought that teachers were at the bottom of the social ladder. One said that none of her friends looked upon teaching as a worthwhile career, so she came to think of teaching as not noble enough and went into pharmacy instead. According to several recent reports on the shortcomings of American public schooling, teaching's lack of appeal for the brightest college students is one of the teaching profession's most worrisome problems. Many articles on teaching, currently popular in newspapers, magazines, and professional education journals, concentrate on the negative aspects of teaching. The expression "teacher burnout" is commonly ascribed to thousands of thoughtful and dedicated teachers who are leaving the profession. Teacher burnout is caused by such problems as violence in the classroom, vandalism, inadequate salaries, involuntary transfers, interfering parents, oversized classes, and excessive paperwork. Even the best teachers cannot solve a child's problems, but many of them believe the public expects them to, and they give up teaching in despair. Despite the more limited financial prospects, the deterioration of the American public's attitude toward teachers, and the problems caused by disruptive students, many of the best students conclude that they want to pursue careers in the classroom after all. The three students mentioned above discovered that they wanted personal fulfillment from their life's work more than they wanted material rewards. Each eventually chose to become a teacher. However, a growing body of evidence shows that such students are exceptions, rather than the rule, in America's more than 1,200 teacher-training programs. Many teacher-training schools are beginning to look at ways to recruit the kind of people who would be inclined toward the positive aspects of teaching. The teaching profession has to become more attractive to good students. Prospective teachers will see increased emphasis by national teacher organizations, state certification agencies, and local districts on improving the status of the profession, as well as on improving teacher salaries. Continued efforts to eliminate jobs teachers do that are not teacher--such as policing the restrooms, hallways, and cafeterias--are important for upgrading the profession. While teaching is not a wise career choice for all, teaching is a noble and rewarding profession for those who indeed seek personal fulfillment from their life's work. The first year of teaching is frequently the most frustrating year in a teacher's life. The experience of solving problems that deal with instruction, students, parents, administrators, and fellow teachers is of immeasurable value for future success.

单选题 In recent years many countries of the world have been faced with the problem of how to make their workers more productive. Some experts claim the answer is to make jobs more varied. But do more varied jobs lead to greater productivity? The evidence shows that while variety certainly makes the worker's life more enjoyable, it does not actually make him work harder. As far as increasing productivity is concerned, then, variety is not an important factor. Other experts feel that giving the worker freedom to do his job in his own way is important. There is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated machinery which must be used in a fixed way. Thus, although freedom of choice may be important, usually very little can be done to create it. Another important consideration is how much a worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are now experimenting with having many small production lines rather than a large one, so that each worker contributes more to the production of the cars on his line. It would seem that not only is degree of the worker's contribution an important factor, therefore, but it is also one we can do something about. To what extent does more money lead to greater productivity? The workers themselves certainly think this is important. But perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if we make their jobs more interesting, they will want neither more money nor shorter working hours.

单选题You must have been troubled by when to say "I love you" because it is one of the greatest puzzles in our life. What if you say it first and your partner doesn"t love you back? Or if they do say it, but you don"t feel they mean it? Being the first to declare your love can be ever racking (紧 张) and risky and can leave you feeling as vulnerable as a turtle (海龟) with no shell. But is the person who says it first really in a position of weakness? Doesn"t it pay to hold back, play it cool and wait until the other half has shown their hand first? "A really good relationship should be about being fair and being equal," says psychologist Sidney Crown. "But love is seldom equal. " All relationships go through power struggles but, he says, if a love imbalance continues for years, the rot will set in. "That feeling of "I"ve always loved you more" may be subverted (颠覆，破坏) for a time, but it never goes away completely and it often emerges in squabbling (大声争吵). " In love, at least, the silent, withholding type is not always the most powerful. "The strongest one in a relationship is often the person who feels confident enough to talk about their feelings," says educational psychologist Ingrid Collins. Psychosexual therapist Paula Hall agrees. "The one with the upper hand is often the person who takes the initiative. In fact, the person who says "I love you" first may also be the one who says "I"m bored with you" first. " Hall believes that much depends on how "I love you" is said and the motivation of the person saying it. "Is it said when they"re drunk? Is it said before their partner files off on holiday, and what it really means is "Please don"t be unfaithful to me"? By saying "I love you", they are really saying "Do you love me?" If so, wouldn"t it just be more honest to say that?" Collins agrees that intention is everything. "It"s not what is said, but how it"s said What it comes down to is the sincerity of the speaker.
