单选题1 Coral reefs are one of the earth's most ancient ecosystems and also the richest, most diverse, and most beautiful ecosystems in any ocean. The huge cities built by corals provide shelter and food for billions of other marine animals. A quarter of all sea creatures depend on coral reefs during some part of their life cycles. 2 In the past century, the ocean's surface temperature has risen an average of 1.8 degrees Fahrenheit. It has taken only this slight increase in sea-surface temperature to sicken the world's coral reefs. The brilliant blue, purple, green, gold, and pink have begun to disappear as a disease called bleaching drains the color and the life from the reefs. Scientists have reported mass bleaching on reefs in the Caribbean, in southern Japan, in Indonesia, and on the world's largest coral reef, the Great Barrier Reef, where the corals have bleached to a dirty white. 3 Bleaching has killed more corals than all other causes combined. More than 16 percent of the world's corals have sickened and died from bleaching. Millions of aquatic animals that depend directly or indirectly on corals have died as well--anemones, sponges, mollusks, shrimp, crabs, fish, turtles, and seabirds--making the loss of corals a catastrophe for the natural world.

单选题Family Matters This month, Wyoming passed a bill that would give legal teeth to the moral obligation to support one's parents. Called the Maintenance of Parents Bill, it received the backing of the Government. That does not mean it hasn't generated discussion. Several members of the Parliament opposed the measure. Others who acknowledged the problem of the elderly poor believed it a disproportionate response. Still others believe it will subvert relations within the family, cynics dubbed it the "Sue Your Son" law. Those who say that the bill does not promote filial responsibility, of course, are right. It has nothing to do with filial responsibility. It kicks in where filial responsibility fails. All the law can do is to provide a safety net where this morality proves insufficient. Wyoming needs this bill not to replace morality, but to provide incentives to show it up. Wyoming faces the problems of an increasing proportion of people over 60 years of age. Demography is inexorable. In 1980, 7.2% of the population was in this bracket. By 2030, the proportion is projected to be 26%. The problem is not old age persen. It is that the ratio of economically active people to economically inactive people will decline. But no amount of government exhortation or paternalism will completely eliminate the problem of old people who have insufficient means to make ends meet. Some people will fall through the holes in any safety net. Traditionally, a person's insurance against poverty in his old age was his family care and support for one's parents is a universal value shared by all civilized societies. The problem in Wyoming is that the moral obligation to look after one's parents is unenforceable. A father can be compelled by law to maintain his children. A husband can be forced to support his wife. But, until now, a son or daughter had no legal obligation to support his or her parents. In 1989, an Advisory Council was set up to look into the problems of the aged. Its report stated with a tinge of complacency that 95% of those who did not have their own income were receiving cash contributions from relations. But what about the 5% who aren't getting relatives' support? They have several options:(a) get a job and work until they die;(b) apply for public assistance (you have to be destitute to apply); or(c) starve quietly. None of these options is socially acceptable. And what if this 5% figure grows, as it is likely to do, as society ages? The Maintenance of Parents Bill was put forth to encourage the traditional virtues that have so far kept Wyoming from some of the breakdowns encountered in other affluent societies. This legislation will allow a person to apply to the court for maintenance from any or all of his children. The court would have the discretion to refuse to make an order if it is unjust. Those who deride the proposal for opening up the courts to family lawsuits miss the point. Only in extreme cases would any parent take his child to court. If it does indeed become law, the bill's effect would be far more subtle. First, it will reaffirm the notion that it is each individual's—not society's—responsibility to look after his parents. Wyoming is still conservative enough that most people will not object to this idea. Second, and more important, it will make those who are inclined to shirk their responsibilities think twice.(A) [■] But to be sued by one's parents would be a massive loss of face. It would be a public disgrace.(B) [■] The hand of the conciliator would be immeasurably strengthened.(C) [■] It is far more likely that some sort of amicable settlement would be reached if the recalcitrant son or daughter knows that the alternative is a public trial.(D) [■] It would be nice to think Wyoming doesn't need this kind of law. Those of us who pushed for the bill will consider ourselves most successful if it acts as an incentive not to have it invoked in the first place.

单选题THE QUEEN ANNE HOUSE 1 The house style that dominated American housing during the 1880s and 1890s was known as Queen Anne, a curious name for an American style. The name was, in fact, a historical accident, originating with fashionable architects in Victorian England who coined it with apparently no reason other than its pleasing sound. The Queen Anne style was loosely based on medieval structures built long before 1702, the beginning year of Queen Anne's reign. 2 A distinctive characteristic found in most Queen Anne houses is the unusual roof shape-- a steeply pitched, hipped central portion with protruding lower front and side extensions that end in gables. It is often possible to spot these distinctive roof forms from several blocks away. Another feature of this style is the detailing, shown in the wood shingle siding cut into fanciful decorative patterns of scallops, curves, diamonds, or triangles. Queen Anne houses are almost always asymmetrical. If you draw an imaginary line down the middle of one, you will see how drastically different the right and left sides are, all the way from ground level to roof peak. A final characteristic is the inviting wraparound porch that includes the front door area and then extends around to either the right or left side of the house. 3 Queen Anne houses faded from fashion early in the twentieth century as the public's taste shifted toward the more modern Prairie and Craftsman style houses. Today, however, Queen Anne houses are favorite symbols of the past, painstakingly and lovingly restored by old-house buffs and reproduced by builders who give faithful attention to the distinctive shapes and detailing that were first popularized more than one hundred years ago.
