Many of the most damaging and life threatening types of weather, such as torrential rains and severe thunderstorms, begin quickly, strike suddenly, and disappear rapidly, de-stroying small regions while leaving neighboring areas untouched. (79) Conventional (普通) computer models of the atmosphere have limited value in predicting short-lived local storms because the available weather data are generally not detailed enough to allow com-puters to see clearly the small atmospheric changes that come before these storms. In most nations, for example, weather-balloon observations are taken just once every twelve hours at location typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large re-gions than they do forecasting specific local events.
Until recently, the observation-intensive approach needed for accurate, very short range forecasts, or "nowcasts",
A. local forecasts
B. short-range forecasts
C. medium-range forecasts
D. long-range forecasts

[单项选择]The hotels are full, Japanese tourists throng the designer stores of Waikiki, and the unemployment rate is a mere 3% of the workforce. So what could possibly knock Hawaii, the "aloha" or "welcome" state, off its wave The answer is that Hawaii’s 1.2million residents may one day get fed up with playing host to overseas visitors, 7million of them this year.
Indeed, some residents are already fed up. KAHEA, an alliance of environmentalists and defenders of native Hawaiian culture, bemoans the pollution caused by the cruise ships and the risk posed by the tourist hordes to creatures such as the dark-rumped petrel and the Oahu tree snail, or to plants like the Marsilea villosa fern. KAHEA has a point, the US Fish & Wildlife Service currently lists some 317 species, including 273 plants, in the Hawaiian islands as threatened or endangered--the highest number of any state in the nation. Even the state flower, the hibiscus brackenridgei, is on the danger list. The loss of species, says

[单项选择]The National Association of Securities Dealers is investigating whether some brokerage houses are inappropriately pushing individuals to borrow large sums on their houses to invest in the stock market. Can we persuade the association to investigate would-be privatizers of Social Security For it is now apparent that the Bush administration’s privatization proposal will amount to the same thing, borrow trillions, put the money in the stock market and hope.
Privatization would begin by diverting payroll taxes, which pay for current Social Security benefits, into personal investment accounts. The government would have to borrow to make up the shortfall. This would sharply increase the government’s debt.
