单选题 Deport Them or Not In a country that defines itself by ideals, not by shared blood, who should be allowed to come, work and live here? In the wake of the Sept. 11 attacks these questions have never seemed more pressing. On Dec. 11, 2001, as part of the effort to increase homeland security, federal and local authorities in 14 states staged "Operation Safe Travel" -raids on airports to arrest employees with false identification (身份证明). In Salt Lake City there were 69 arrests. But those captured were anything but terrorists, most of them illegal immigrants from Central or South America. Authorities said the undocumented workers' illegal status made them open to blackmail (讹诈) by terrorists. Many immigrants in Salt Lake City were angered by the arrests and said they felt as if they were being treated like disposable goods. Mayor Anderson said those feelings were justified to a certain extent, "We're saying we want you to work in these places, we're going to look the other way in terms of what our laws are, and then when it's convenient for us, or when we can try to make a point in terms of national security, especially after Sept. 11, then you're disposable. There are whole families being uprooted for all of the wrong reasons." Anderson said. If Sept. 11 had never happened, the airport workers would not have been arrested and could have gone oil quietly living in America, probably indefinitely. Ana Castro, a manager at a Ben & Jerry's ice cream shop at the airport, had been working 10 years with the same false Social Security card when she was arrested in the December airport raid. Now she and her family are living under the threat of deportation (驱逐出境). Castro's case is currently waiting to be settled. While she awaits the outcome, the government has granted her permission to work here and she has returned to her job at Ben & Jerry's.

单选题Ancient Egypt Brought Down by Famine Even ancient Egypt's mighty pyramid (金字塔) builders were powerless in the face of the famine (饥荒) that helped bring down their civilization around 2180 BC. Now evidence collected from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame-and the same or worse could happen today. The ancient Egyptians depended on the Nile's annual floods to irrigate their crops. But any change in climate that pushed the African monsoons (季风) southwards out of Ethiopia would have reduced these floods. Declining rains in the Ethiopian highlands would have meant fewer plants to stabilize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment (沉积) from the White Nile. Blue Nile mud has a different isotope (同位素) signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river. Krom reasons that during periods of drought, the amount of Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4500 to 4200 years ago, immediately came before the fall of the Egypt's Old Kingdom. The weakened waters would have been disaster for the Egyptians. "Changes that affect food supply don't have to be very large to have a ripple (波浪) effect in societies. " says Bill Ryan of the Lamont Doherty Earth Observatory in New York. Similar events today could be even more devastating, says team member Daniel Stanley, a scientist from the Smithsonian Institution in Washington D. C. "Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. /

单选题A Society Without a Formal Authority In the seventeenth century, European soldiers who came across some Indian groups in the western Great Lakes found that several native tribes (部落) were living in the area without a formal leadership system. They appeared to be "quite friendly with each other without a formal authority!" Not only did the Indians appear to lack a formal system of authority, but they also deeply hated any efforts to control their actions. All members of the tribes knew what was required of them by lifelong (一生的) familiarity with the tasks of the area. These tasks tended to be simple, since the Indians' rate of social change was slow. Thus, although subgroups such as soldiers had recognized leaders, no real authority was required. Rather than giving direct orders (which were considered rough), members of the tribes would arouse others to action by examples. It would be difficult, if not impossible, to carry out such a system in our own society. Most of us have gown up under one authority or another for as long as we can remember. Our parents, our teachers, our bosses, our government all have the recognized right under certain conditions to tell us what to do. The authority is so much a part of our culture that it is hard for us to imagine a workable society without it. We have been used to relying on authority to get things done and would probably be uncomfortable with the Indian methods of examples on a large scale. Of course, the major reason why the Indian system would not be suitable for us is that our society is too large. The number of tasks that various members of our society have to perform often under tight time and resource limitations could not be treated by the Indian system, in modern societies, the formal authority system is necessary to achieve any social objectives.

单选题{{B}}第二篇{{/B}} {{B}} Home Heating{{/B}} Central heating became popular only after the Civil War. Typically, coal-burning furnaces (火炉) fueled the early systems. Natural gas had developed into the leading fuel by 1960. Its acceptance resulted in part from its wide uses. Because it comes primarily from U.S. and Canadian fields, natural gas is also less vulnerable (脆弱的) than oil is to war. Oil remains the most important fuel in a few areas, such as New England. Electric heating dominates most areas with mild winters and cheap electricity, including the South and the Northwest. It was made popular at least in the South by the Iow cost of adding electric heating to new houses built with air-conditioning. Bottled gas, which is somewhat more expensive than utility gas, is the fuel of choice in rural areas not served by utility pipelines. Wood is the leading heating fuel in just a few rural counties. Home heating, which accounts for less than 7 percent of all energy consumed in the U.S., has had a commendable (值得赞扬的) efficiency record: from 1978 to 1997, the amount of fuel consumed for this purpose declined 44 percent despite a 33 percent increase in the number of housing units and an increase in house size. The U. S. Department of Energy, however, forecasts that energy used in home heating will rise by 14 percent over the next two decades. That rise is small considering an expected 21 percent increase in the number of houses and the trend toward larger houses. Natural gas and electricity will probably dominate the home heating market for the next two decades. Solar (太阳的) heating never became popular because of cost and limited winter sunlight in most areas; in 2000 only 47, 000 homes relied on it.
