Many of the most damaging and life threatening types of weather torrential rains, severe thunderstorms, and tornadoes(龙卷风,)--begin quickly, strike suddenly, and disappear rapidly, destroying small regions while leaving neighboring areas untouched. Such event as a tornado struck the north eastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $ 250 million, the highest ever for any Canadian storm.
Conventional computer models of the atmosphere have limited value in predicting short lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the subtle (微妙的)atmospheric changes that come before these storms. In most nations, for example, weather - balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.
Until recently, the observation intensive approach needed for accurate, very short - range forecasts, or "Now casts", was not feasible. The cost of e quipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were hard to overcome. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modem computers can quickly compile and analyze this large volume of weather information. Meteorologists(气象学者) and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, now casting is becoming a reality.

How many really suffer as a result of labor market problems? This is one of the most critical yet contentious social policy questions. In many ways, our social statistics exaggerate the degree of hardship.
Unemployment does not have the same dire consequences today as it did in the 1930's when most of the unemployed were primary breadwinners, when income and earnings were usually much closer to the margin of subsistence, and when there were no countervailing social programs for those failing in the labor market. Increasing affluence, the rise of families with more than one wage earner, the growing predominance of secondary earners among the unemployed, and improved social welfare protection have unquestionably mitigated the consequences of joblessness. Earnings and income data also overstate the dimensions of hardship. Among the millions with hourly earnings at or below the minimum wage level, the overwhelming majority are from multiple-earner, relatively affluent families. Most of those counted by the poverty statistics are elderly or handicapped or have family responsibilities which keep them out of the labor force, so the poverty statistics are by no means an accurate indicator of labor market pathologies.
Yet there are also many ways our social statistics underestimate the degree of labor-market- related hardship. The unemployment counts exclude the millions of fully employed workers whose wages are so low that their families remain in poverty. Low wages and repeated or prolonged unemployment frequently interact to undermine the capacity for self-support. Since the number experiencing joblessness at some time during the year is several times the number unemployed in any month, those who suffer as a result of forced idleness can equal or exceed average annual unemployment, even though only a minority of the jobless in any month really suffer. For every person counted in the monthly unemployment tallies, there is another working part-time because of the inability to find full-time work, or else outside the labor force but wanting a job. Finally, income transfers in our country have always focused on the elderly, disabled, and dependent, neglecting the needs of the working poor, so that the dramatic expansion of cash and in-kind transfers does not necessarily mean that those failing in the labor market are adequately protected.
As a result of such contradictory evidence, it is uncertain whether those suffering seriously as a result of thousands or the tens of millions, and, hence, whether high levels of joblessness can be tolerated or must be countered by job creation and economic stimulus. There is only one area of agreement in this debate--that the existing poverty, employment, and earnings statistics are inadequate for one of their primary applications, measuring the consequences of labor market problems.
Which of the following is the principal topic of the passage? ______
A.What causes labor market pathologies that result in suffering.
B.Why income measures are imprecise in measuring degrees of poverty.
C.Which of the currently used statistical procedures are the best for estimating the incidence of hardship that is due to unemployment.
D.How social statistics give an unclear picture of the degree of hardship caused by tow wages and insufficient employment opportunities.

Now that the damage inflicted by the Asian financial crisis looks like it was caused by an economic neutron bomb. The crisis has hurt great numbers of people, but has left the main structures of the world economy standing. The worst of the direct impact may be over. Many of the hardest-hit countries are on the road to recovery, financial "contagion" has been contained and world economic growth seems set to pick up soon.
The most important development, however, is a non-event: the collapse of global capitalism has not occurred. Instead, the post-crisis world is likely to be even more market-oriented than the one that preceded it, with a proliferation of new rules and practices that will help markets to operate more smoothly. The countries recovering best, such as Thailand and South Korea, are doing so by moving further in a free-market direction. None of the affected nations has tried to isolate itself from the global economy, and the widely feared worldwide wave of protectionism has not yet materialized.
Nor has there been the great rethinking of economic globalization that some feared and others advocated. The critics of global capitalism pounced on the crisis as proof of globalization's fatal flaws. Their analyses often concluded that "there must be something better." On the contrary, economists have taken free-market principles as the starting point for new ideas, not called them into question.
There has been much criticism of the so-called Washington consensus—the traditional free-market orthodoxy that uniformly prescribes fiscal discipline, deregulation, and financial liberalization. Partly as a result of the crisis, a new consensus simply adds extra prescriptions—such as better financial supervision, labor market, etc.—to the list. It is an elaboration of the original consensus, not a new departure.
Numerous studies also show that engagement in the global economy leads to higher growth and helps to reduce poverty in developing countries. Today's economic arguments are not over fundamental free-market policies, but what must be done to supplement them. Likewise, the efforts to devise a new "international financial architecture" in the wake of the crisis, due to continue during the spring meetings of the World Bank and the International Monetary Fund in Washington, will not involve rebuilding the system from scratch. The aim is to make incremental improvements in financial rules and practices that will oil the wheels of the market system, not to trade it in for a non-existent new model.
What is the main idea of the first paragraph?
A.After the severe Asian Financial Crisis, the world economy began to recover.
B.Asian Financial Crisis is as devastating as a neutron bomb and causes great damage.
C.There are still direct and indirect impacts so that the economy cannot recover.
D.The direct impact of Asian Financial Crisis has gone.
