单选题{{B}}Text 4{{/B}} Many Americans regard the jury system as a concrete expression of crucial democratic values, including the principles that all citizens who meet minimal qualifications of age and literacy are equally competent to serve on juries; that jurors should be selected randomly from a representative cross section of the community; that no citizen should be denied the right to serve on a jury on account of race, religion, sex, or national origin ; that defendants are entitled to trial by their peers; and that verdicts should represent the conscience of the community and not just the letter of the law. The jury is also said to be the best surviving example of direct rather than representative democracy. In a direct democracy, citizens take turns governing themselves, rather than electing representatives to govern for them. But as recently as in 1968, jury selection procedures conflicted with these democratic ideals. In some states, for example, jury duty was limited to persons of supposedly superior intelligence, education, and moral character. Although the Supreme Court of the United States had prohibited intentional racial discrimination in jury selection as early as the 1880 case of Strauder v. West Virginia, the practice of selecting so-called elite or blue-ribbon juries provided a convenient way around this and other antidiscrimination laws. The system also failed to regularly include women on juries until the mid-20th century. Although women first served on state juries in Utah in 1898, it was not until the 1940s that a majority of states made women eligible for jury duty. Even then several states automatically exempted women from jury duty unless they personally asked to have their names included on the jury list. This practice was justified by the claim that women were needed at home, and it kept juries unrepresentative of women through the 1960s. In 1968, the Congress of the United States passed the Jury Selection and Service Act, ushering in a new era of democratic reforms for the jury. This law abolished special educational requirements for federal jurors and required them to be selected at random from a cross section of the entire community. In the landmark 1975 decision Taylor v. Louisiana, the Supreme Court extended the requirement that juries be representative of all parts of the community to the state level. The Taylor decision also declared sex discrimination in july selection to be unconstitutional and ordered states to use the same procedures for selecting male and female jurors.

单选题Cars account for half the oil consumed in the U.S., about half the urban pollution and one fourth the greenhouse (温室) gases. They take a similar toll (损耗) of resources in other industrial nations and in the cities of the developing world. As vehicle use continues to increase in the coming decade, the U.S. and other countries will have to deal with these issues or else face unacceptable economic, health-related and political costs. It is unlikely that oil prices will remain at their current low level or that other nations will accept a large and growing U.S. contribution to global climatic change. Policymakers, and industry have four options: reduce vehicle use, increase the efficiency and reduce the emissions of conventional gasoline-powered vehicles, switch to less harmful fuels, or find less polluting driving systems. The last of these—in particular the introduction of vehicles powered by electricity—is ultimately the only sustainable option. The other alternatives are attractive in theory but in practice are either impractical or offer only marginal improvements. For example, reduced vehicle use could solve traffic problems and a host of social and environmental problems, but evidence from around the world suggests that it is very difficult to make people give up their cars to any significant extent. In the U.S., mass-transit ridership and carpooling (合伙用车) have declined since World War II. Even in western Europe, with fuel prices averaging more than $ 1 a liter (about $ 4 a gallon) and with easily accessible mass transit and dense populations, cars still account for 80 percent of all passenger travel. Improved energy efficiency is also appealing, but alternative fuel economy has barely made any progress in 10 years. Alternative fuels such as natural gas, burned in internal-combustion engines, could be introduced at relatively low cost, but they would lead to only marginal reductions in pollution and greenhouse emissions (especially because oil companies are already spending billions of dollars every year to develop less polluting types of gasoline).

单选题Text 2 The modern cult of beauty is a success in so far as more women retain their youthful appearance to a greater age than in the past. "Old ladies" are already becoming rare. In a few years, we may well believe, they will be extinct. White hair and wrinkles, a bent back and hollow cheeks will come to be regarded as medievally old-fashioned. The crone of the future will be golden, curly and cherry-lipped, and slender. This desirable consummation will be due in part to skin foods and injections of paraffin-wax, facial surgery, mud baths, and paint, in part to improved health, due in its turn to a more rational mode of life. Ugliness is one of the symptoms of disease, beauty of health. In so far as the campaign for beauty is also a campaign for more health, it is admirable and, up to a point, genuinely successful. Beauty that is merely the artificial shadow of these symptoms of health is intrinsically of poorer quality than the genuine article. Still, it is a sufficiently good imitation to be sometimes mistakeable for the real thing. The apparatus for mimicking the symptoms of health is now within the reach of every moderately prosperous person; the knowledge of the way in which real health can be achieved is growing, and will in time, no doubt, be universally acted upon. When that happy moment comes, will every woman be beautiful—as beautiful, at any rate, as the natural shape of her features, with or without surgical and chemical aid, permits? The answer is emphatically: No. For real beauty is as much an affair of the inner as of the outer self. The beauty of a porcelain jar is a matter of shape, of color, of surface texture. The jar may be empty or tenanted by spiders, full of honey or stinking slime—it makes no difference to its beauty or ugliness. But a woman is alive, and her beauty is therefore not skin deep. The surface of the human vessel is affected by the nature of its spiritual contents. I have seen women who, by the standards of a connoisseur of porcelain, were ravishingly lovely. Their shape, their colour, their surface texture were perfect. And yet they were not beautiful. For the lovely vase was either empty or filled with some corruption. Spiritual emptiness or ugliness shows through. And conversely, there is an interior light that can transfigure forms that the pure aesthetician would regard as imperfect or downright ugly. There are numerous forms of psychological ugliness. There is an ugliness of stupidity, for example, of unawareness (distressingly common among pretty women). An ugliness also of greed, of lasciviousness, of avarice. All the deadly sins, indeed, have their own peculiar negation of beauty. On the pretty faces of those especially who are trying to have a continuous "good time", one sees very often a kind of bored sullenness that ruin all their charm. I remember in particular two young American girls I once met in North Africa. Form the porcelain specialist's point of view, they were extremely beautiful. But a sullen boredom was so deeply stamped into their fresh faces, their gait and gestures expressed so weary a listlessness, that it was unbearable to look at them. These exquisite creatures were positively repulsive.

单选题{{B}}Passage Three{{/B}} People enjoy talking about "firsts." They like to remember their first love or their first car. But not all firsts are happy ones. Few people enjoy recalling the firsts that are bad. One of history's bad but important firsts was the first car accident. Autos were still young when it happened. The crash took place in New York City. The year was 1896. The month was May. A man from Massachusetts was visiting the city in his new car. At the time, bicycle riders were still trying to get used to the new set of wheels on the road. No one is sure who was at fault. In any case, the bike and the car collided. The man on the bike was injured. The driver of the car had to stay in jail and wait for the hospital report on the bicycle rider. Luckily, the rider was not killed. Three years later, another automobile first took place. The scene was again New York City, a real estate broker named Henry Bliss stepped off a streetcar. He was hit by a passing car. Once again, no one is sure just how it happened or whose fault it was. The driver of the car was put in jail. Poor Mr. Bliss became the first person to die in a car accident.

单选题(84) Cancer is among the top killer diseases in our society today and scientists have found out that stress helps to bring it on. It is worthwhile to consider, therefore, what are the causes of stress in our life, and whether we can do anything about them. Are we under-employed, or overburdened with too many responsibilities? Do we have a right balance of work and leisure in our lives? Are our relationships with family, friends or fellow workers all they should be? All these things can be a cause of stress, and it is best to face them honestly, and to bring our frustrations into the open. People who have a good row and then forget it are doing their health more good than those who bottle up their feelings. (85) If our self-examination has brought any causes of stress to light, let us consider what we can do about them. It is possible to change jobs. We can make more leisure and fill it more happily, if we will accept a different living standard. We can improve our personal relationships by a different attitude. It is we who allow other people to make ourselves unhappy. Often the little things that disturb us are not worth an hour's anger. The teaching in the Bible "Let not the sun go down upon your wrath" is good advice from the health point of view as well as the religious.
