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?____ 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. And 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】

3、 Happiness If your sense of well-being fluctuates with stock market, you might be comforted to know that money can\'t buy you happiness anyway. In one American study conducted in 1993, level of income was shown to have an inverse relation to happiness: The group whose income had declined was happier overall than the group whose income had increased. A soon-to-be published review of the hundreds of studies on this subject supports the 1993 findings. In developed countries, the correlation between income and happiness is close to zero and sometimes negative. With a correlation between level of income and happiness somewhere between 0.12 and 0.18, the United States is near the bottom of the list; that factors other than income are overwhelmingly more important in explaining happiness. Also, as our material wealth increases, the gap between income and satisfaction with life seems to be widening. Predictably, money has its most positive effect on the poor, but once a person has achieved a minimal standard of living level of income has almost nothing to do with happiness. Close relationship, rather than money, is the key to happiness. Indeed, the number of one\'s personal friends is a much better indicator of overall satisfaction with life than personal wealth. One stands a better chance of achieving a satisfying life by spending time with friends and family than by striving for higher income. Incidentally, in the US, as people become richer, the probability of divorce increases. Our need for companionship is partly biological. All primates respond with pleasure to demonstrations of affection and with pain to loss of companionship. Isolated monkeys will sacrifice food just for the glimpses of another monkey. By ignoring our biologically programmed need for each other, we risk physical and mental distress. A recent cross-national study of mental depression in the US found that in advanced countries, there is a rising tide of major depression. Teenage suicides have increased in recent decades in almost all advanced countries. Moreover, in the US since World War Ⅱ, there has been an actual decline in the proportion of people who report themselves to be "very unhappy. " You can easily test the claim that companionship exceeds wealth as a source of happiness. Ask yourself which has a greater influence on your satisfaction with life: your income or the affection of your intimate companions and the well-being of your children? Conversely, which would make you more depressed: a reduction in salary or a divorce and isolation from your friends? Capitalism succeeds in creating material riches, but it is less successful in building companionable societies and protecting family integrity. But developing countries still have much work to do in pursuing material wealth, where a rise in productivity still greatly increases happiness. For poorer countries, the time is not yet ripe for a shift in priorities from wealth accumulation to companionship. Can we afford to believe that the pursuit of material gain will lead to self-fulfillment? We should continue to enjoy our wealth in good company, or else we may find that it is not satisfying. Which of the following is the least likely cause of one\'s unhappiness in advanced countries? 【单选题】

A.Loss of friends.

B.Reduction of income.

C.Death of a family member.

D.Divorce.

正确答案:B

答案解析:Capitalism (advanced countries) succeeded in creating material riches, but it is less successful in building companionable societies and protecting family integrity. (But developing countries still have much work to do in pursuing material wealth, where a rise in productivity still greatly increases happiness. For poor countries, the time is not yet ripe for a shift in priorities from wealth accumulation to companionship. 该句说“资本主义（制度）（借助后句中分别出现的‘发展中国家’和‘穷国’，判断Capitalism是指“发达国家”）成功地创造了物质财富，但是它在建立和谐社会和保护家庭的完整上就不太成功”，从这个句子可以推出结论：资本主义国家的不足之处：不能很好地维持社会的和谐和家庭的完整应该是造成资本主义国家的人民不快乐的原因，选项A、C和D都涉及社会和家庭，因此判断B（收入的减少）是答案。
