1、BFT 阅读（综合）-试卷 29 及答案解析(总分：40.00，做题时间：90 分钟)一、Part 2(总题数：4，分数：40.00)1. For some years, there has been a plan to solve the water shortage problem by moving huge icebergs halfway round the world from the Antarctic Ocean to arid region such as the north of Mexico, California, Arabia or parts of Africa.

2、The plan has never been implemented, however, because of the great cost involved in using giant tugboats to move the icebergs. 2. The solution to this problem of cost would be to make self-propelled icebergs, thus removing the need for ships and expensive fuel. The iceberg would be its own tugboat.

3、This is how it would work: liquid freon is pumped under high pressure into heat exchangers submerged in the water. As the freon leaves the iceberg(temperature: 32F)and comes into contact with the water(temperature: 50F52F), it turns into gas and expands rapidly. As it does so, it turns turbines whic

4、h drive the propellers. The freon is then returned to the iceberg where it liquefies and goes through the process again. 3. The plan is then as follows. A ship would sail to the Antarctic and select an iceberg 2 miles wide, 5 miles long and about 1,000 feet thick. A crew of 40 to 50 people would the

5、n bring the iceberg to where it is needed. They would live in special quarters, heated by solar energy. Helicopters would bring equipment, supplies and food. When the “engine“ was in place, the iceberg would travel at about one and a half knots, although in a favorable current, it would move two or

6、three times as fast. The Humboldt Current, for example, off the coast of South America could bring icebergs from the Antarctic to the coast of Mexico or California. 4. The next problem is what to do with it when it arrives at its destination. Lying off the coast of some dry area, the iceberg would b

7、e enclosed in an enormous plastic cocoon, open on the top and the bottom but enclosing all the sides. This would prevent the iceberg from floating away and also enables the fresh water to be piped off the top as it melts. The iceberg would take about a year to melt. 5. The cost of this operation is

8、estimated at about $65 million for the first iceberg and $15 million for subsequent ones because the equipment can be used again. The operation is therefore worth considering because a 2 miles by 5 miles by 1,000 feet iceberg holds a trillion gallons of water, worth about $200 million at todays pric

Few social problems have increased so suddenly or been dramatized so effectively as the plight of the homeless in the 1980s and 1990s. Once an invisible people who could easily be

15、 ignored, the homeless are now recognized everywhere on the streets and in the public facilities of major cities. 2. The number of homeless people in underdeveloped societies in the mid-1980s was estimated by the United Nations to be more than 100 million. The so-called “new“ homeless live in the de

16、veloped, industrialized nations of Europe, North America, and East Asia. Accurate statistics have been impossible to verify, in part because of the conflicting viewpoints on the subject of homelessness. Politicians, lawyers, and others who become advocates for the homeless have said that there are f

17、rom 2-3 million homeless in the United States alone. Others who have studies the problem from a less sympathetic point of view suggest that the number is closer to 300,000. 3. One reason for statistical uncertainty is the composition of the homeless population. Some families suffer temporary poverty

18、 because of loss of a job. Unable to afford rent or mortgage payments, they may temporarily join the ranks of the homeless for a period of days or weeks(or they may live with relatives). Once another job is found, the family can usually afford shelter once more. 4. The number of those who are truly

19、homeless consists of possibly 3 percent or less of the very poor. Their most common characteristic is poverty, though some work at least part-time, while others receive various kinds of welfare payments. 5. The National Institute of Mental Health has estimated that one third of the homeless in the 1

20、980s were former mental patients who had been discharged under deinstitutionalization programs. Many of the homeless are also addicted to drugs or alcohol or both. Some are victims of structural unemployment, temporary, but massive, changes in an economy. Others become homeless when the eligibility

21、rules for assistance change or when the supply of low-rent housing runs out. Some members of the homeless population are voluntary in the sense that they leave intolerable situations within their former homes. Battered wives and abused or neglected children become runaways, living on the streets or

22、in shelters opened by charities. In Japan, many men reportedly have dropped out of the economy voluntarily for such reasons as stress, old age, indifference, or to escape family problems. 6. Government responses to the problem have varied. Canada and the United States have no laws on homelessness, b

23、ut government agencies provide funds to operate shelters and soup kitchens. England has a Homeless Persons Act, enacted in 1977, that requires local authorities to house the homeless. In an attempt to improve housing for the poor, the UN declared 1987 the International Year of Shelter for the Homele
