1、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. ____ the last “official” stocks of live virus bred mistrust of the US and Russia, for no obvious gain.Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines. So one again there\'s a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US and Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

2、They say Ireland\'s the BestIreland is the best place in the world to live in for 2005, according to a life quality ranking that appeared in Britain\'s Economist magazine last week.The ambitious attempt to compare happiness levels around the world is based on the principle that wealth is not the only measure of human satisfaction and well-being.The index of 111 countries uses data on incomes, health, unemployment, climate, political stability, job security, gender equality as well as what the magazine calls "freedom, family and community life".Despite the bad weather, troubled health service, traffic congestion (拥挤), gender inequality, and the high cost of living, Ireland scored an impressive 8.33 points out of 10.That put it well ahead of second-place Switzerland, which managed 8.07. Zimbabwe, troubled by political insecurity and hunger, is rated the gloomiest (最差的) , picking up only 3.89 points."Although rising incomes and increased individual choices are highly valued, " the report said, "some of the factors associated with modernization such as the breakdown in traditional institutions and family values in part take away from a positive impact."Ireland wins because it successfully combines the most desirable elements of the new with the preservation of certain warm elements of the old, such as stable family and community life. "The magazine admitted measuring quality of life is not a straightforward thing to do, and that its findings would have their critics.No. 2 on the list is Switzerland. The other nations in the top 10 are Norway, Luxembourg, Sweden, Australia, Iceland, Italy, Denmark and Spain.The UK is positioned at No. 29, a much lower position chiefly because of the social and family breakdown recorded in official statistics. The US, which has the second highest per capita GDP after Luxembourg, took the 13th place in the survey. China was in the lower half the league at 60th.Cost of living in Ireland is pretty high.【单选题】

3、Breast Cancer Deaths Record LowThe number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a year for the first time since records began.The Cancer Research UK data showed that 11,990 women died in the UK in 2007.The previous lowest figure had been recorded in 1971-the year records began after which it rose steadily year by year until the late 1980s.Professor Peter Johnson, Cancer Research UK\'s chief clinician said, "It\'s incredibly encouraging to see fewer women dying from breast cancer now than at any time in the last 40 years, despite breast cancer being diagnosed more often. "Research has played a crucial role in this progress leading to improved treatments and better management for women with the disease."The introduction of the NHS (国民保健制度) breast screening program has also contributed as women are more likely to survive the earlier cancer is diagnosed. "Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease, a 50% rise in 25 years.The number of deaths peaked in 1989, when 15,625 women died. It then fell by between 200 and 400 deaths each year until 2004.There was a slight rise in 2005 and then two years of falls.Dr Sarah Cant, policy manager at Breakthrough Breast Cancer, said, "It is great news that fewer women are dying from breast cancer and highlights the impact of improved treatments, breast screening and awareness of the disease. " ."However, this is still too many women and incidence of the disease is increasing year by year."The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity（肥胖） and alcohol consumption.The rate of breast cancer diagnosis in the UK has been dropping.【单选题】

4、The motorcarSome pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.The motorcar will undoubtedly. change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion. One proposed solution to this problem is the automated highway system.When the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car\'s movements.The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.What provides autos with electric power in an automated highway system?【单选题】

A.A rail.

B.An engine.

C.A retractable arm.

D.A computer controller.

正确答案:A

答案解析:根据常识来判断，“可伸缩得手臂”只是用来连接汽车与铁轨的工具，是能源的传导器，也就是说，提供能源的不是“可伸缩的手臂”，而“铁轨”，所以答案为A。
