单选题Text 3 It's wonderful how everyone agrees (or fears to disagree) that genetic discrimination is a bad thing. Your genes are beyond your control. Why should you be punished for them? Unfortunately, genetic discrimination is universal, inevitable and, in some ways, essential. Leaving aside the hot issue of intelligence, consider clearly genetic traits such as musical or athletic talent. Practice, practice will get you to Carnegie Hall, but only if you're born on the right bus. The notion of not discriminating on the basis of inborn talent is not even an abstract ideal, the world would be a poorer place if it did not distinguish between me and Yo-Yo Ma in doling out opportunities to be a concert cellist. As we learn more about the human genome, we'll learn that more and more of the traits we reward have a genetic component. Martin Luther King said we should all be judged on "the content of our character." But if a disposition to hard work or courage or creative imagination turns out to have a large genetic component, should we still judge people based on these qualities? Then, too, the world discriminates on the basis of clearly genetic traits, such as physical beauty, that are irrelevant in most circumstances. Occasionally, some zealot proposes to ban this kind of discrimination, too. But it will never happen. So what is the limiting principle on banning genetic discrimination? Where do we stop? Right now, the universal consensus makes a distinction between the results of genetic tests and genetic traits that reveal themselves in some other way. It seems unfair and arbitrary that your fate in life should be determined in any important way by what a drop of your blood reveals under a microscope; but logically, there is no difference between this and letting your fate be determined by how tall or musically gifted you are. A Juilliard tryout is, in part, a genetic test. If there were a blood test for musical talent, as there may be some day, it would do the same thing more efficiently. A blood test might even be fairer than the crude substitutes we use instead to judge and choose among people: It would zero in on the trait we really need to discriminate about and reduce discrimination on the basis of traits that are irrelevant. Some people say the danger is that genetic testing will encourage irrelevant discrimination; employers will overreact and refuse to hire you even though your actual likelihood of getting Alzheimer's before your retirement is minuscule. But discriminationby mistake will often bring its own punishment, like any business misjudgment. The real problem is discrimination that makes perfect sense. A health insurer is not crazy or stupid to want to keep people out of its insurance pool if they're more likely to get sick. Nor is the company evil to do this if the law allows it. The idea of insurance is to protect against unpredictable costs. Ignoring predictable costs, when your competitors aren't required to do the same, is a recipe for bankruptcy.

单选题As Dr. Samuel Johnson said in a different era about ladies preaching the surprising thing about computers is not that they think less well than a man, but that they think at all. The early electronic computer did not have much going for it except a marvelous memory and some good math skills. But today the best models can be wired up to learn by experience, follow an argument, ask proper questions and write poetry and music. They can also carry on somewhat puzzling conversations. Computers imitate life. As computers get more complex, the imitation gets better. Finally, the line between the original and the copy becomes unclear. In another 15 years or so, we will see the computer as a new form of life. The opinion seems ridiculous because, for one thing, computers lack the drives and emotions of living creatures. But drives can be programmed into the computer's brain just as a new form of life. Computers match people in some roles, and when fast decisions are needed in a crisis, they often surpass them. Having evolved when the pace of life was slower, the human brain has an inherent defect that prevents it from absorbing several streams of information simultaneously and acting on them quickly. Throw too many things at the brain at one time and it freezes up. We are still in control, but the capabilities of computers are increasing at a fantastic rate, while raw human intelligence is changing slowly, if at all. Computer power has increased ten times every eight years since 1846. In the 1990s, when the sixth generation appears, the reasoning power of an intelligence built out of silicon will begin to match that of the human brain. That does not mean the evolution of intelligence has ended on the earth. Judging by the past, we can expect that a new species will arise out of man, surpassing his achievements as he has surpassed those of his predecessor. Only a carbon chemistry enthusiast would assume that the new species must be man's flesh-and-blood descendants. The new kind of intelligent life is more likely to be made of silicon.

单选题{{B}}Directions: There are five reading passages in this part. Each passage is followed by four questions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.{{/B}}{{B}}Passage One{{/B}} Suppose you have a brick and a sponge which are exactly the same size. The brick and the sponge will occupy the same amount of space, but they will not weigh the same. If two things are exactly the same size, but differ in weight, then they have different densities. The one with the greater weight for the same size has the greater density. The one with lower weight for the same size has the lower density. Now apply this idea to {{U}}fluids{{/U}}. You know that water and air expand when they are heated and therefore become less dense. If you poured a cupful of very hot water and let it cool, you would have a little less than a cupfull of cool water. If you weighed a cupful of very hot water and a cupful of cool water, the cupful of very hot water would weigh a little less. The cupful of cool water, being a little heavier than the cupful of hot water, would really have a little more water in it. Cold water is denser than hot water. Likewise, cold air is denser than hot. air. The greater weigh! of !he denser material makes it fall to the bottom of the container. It pushes up the less dense material.

单选题Although genetic mutations in bacteria and viruses can lead to epidemics, some epidemics are caused by bacteria and viruses that have undergone no significant genetic change. In analyzing the latter, scientists have discovered the importance of social and ecological factors to epidemics. Poliomyelitis, for example, emerged as an epidemic in the United States in the twentieth century, by then, modern sanitation was able to delay exposure to polio until adolescence or adulthood, at which time polio infection produced paralysis. Previously, infection had occurred during infancy, when it typically provided lifelong immunity without paralysis. Thus, the hygiene that helped prevent typhoid epidemics indirectly fostered a paralytic polio epidemic. Another example is Lyme disease, which is caused by bacteria that are transmitted by deer ticks. It occurred only sporadically during the late nineteenth century, but has recently become prevalent in parts of the United States, largely due to an increase in the deer population that occurred simultaneously with the growth of the suburbs and increased outdoor recreational activities in the deer's habitat. Similarly, an outbreak of dengue hemorrhagic fever became an epidemic in Asia in the 1950s because of ecological changes that caused Aedesaegypti, the mosquito that transmits the dengue virus, to proliferate. The stage is now set in the United States for a dengue epidemic because of the inadvertent introduction and wide dissemination of another mosquito, Aedesalbopictus.

单选题Americans are pound of their variety and individuality, yet they love and respect few things more than a uniform, whether it is; the uniform of an elevator operator or the uniform of a five-star general. Why are uniforms so popular in the United States? Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian (百姓的) clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears uniform tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity (身 份) than to step out of uniform? Uniforms also have many practical benefits. They save on other clothes. They save on laundry bills. They are tax-deductible (可减税的). They are often more comfortable and more durable than civilian clothes. Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least. Uniforms also give rise to some practical problems. Though they are long-lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes. (294 words)

单选题One of the many pleasures of watching Mad Men , a television drama about the advertising industry in the early 1960s, is examining the ways in which office life has changed over the years. One obvious change makes people feel good about themselves: they no longer treat women as second-class citizens. But the other obvious change makes them feel a bit more uneasy : they have lost the art of enjoying themselves at work. The ad-men in those days enjoyed simple pleasures. They puffed away at their desks. They drank throughout the day. They had affairs with their colleagues. They socialised not in order to bond , but in order to get drunk. Nowadays many companies are obsessed with fun. Software firms in Silicon Valley have installed rock-climbing walls in their reception areas and put inflatable animals in their offices. Wal-Mart orders its cashiers to smile at all and sundry. The cult of fun has spread like some disgusting haemorrhagic disease. This cult of fun is driven by three of the most popular management fads of the moment: empowerment, engagement and creativity. Many companies pride themselves on devolving power to front-line workers. But surveys show that only 20% of workers are" fully engaged with their job ". Even fewer are creative. Managers hope that " fun" will magically make workers more engaged and creative. But the problem is that as soon as fun becomes part of a corporate strategy it ceases to be fun and becomes its opposite—at best an empty shell and at worst a tiresome imposition. The most unpleasant thing about the fashion for fun is that it is mixed with a large dose of pressure. Boston Pizza encourages workers to send" golden bananas" to colleagues who are "having fun while being the best". Behind the" fun" there often lurks some crude management thinking: a desire to brand the company as better than its rivals, or a plan to boost productivity through team-building. Twitter even boasts that it has" worked hard to create an environment that spawns productivity and happiness". While imposing fake fun on their employees, companies are battling against the real thing. Many force smokers to huddle outside like furtive criminals. Few allow their employees to drink at lunch time, let alone earlier in the day. A regiment of busybodies— from lawyers to human resources functionaries—is waging war on office romance, particularly between people of different ranks. The merchants of fake fun have met some resistance. When Wal-Mart tried to impose alien rules on its German staff—such as compulsory smiling and a ban on affairs with coworkers—it touched off a guerrilla war that ended only when the supermarket chain announced it was pulling out of Germany in 2006. But such victories are rare. For most wage slaves forced to pretend they are having fun at work, the only relief is to poke fun at their tormentors . Mad Men reminds people of a world they have lost—a world where bosses did not tbink that"fun" was a management tool and where employees could happily quaff Scotch at noon. Cheers to that.
