单选题Irish Dolphins May Have a Unique Dialect Irish scientists monitoring dolphins living in a river estuary in the southwest of the country believe they may have developed a unique dialect to communicate with each other. The Shannon Dolphin and Wildlife Foundation (SDWF) has been studying a group of up to 120 bottle-nose dolphins in the River Shannon using vocalizations collected on a computer in a cow shed near the River Shannon. As part of a research project, student Ronan Hickey digitized and analyzed a total of 1,882 whistles from the Irish dolphins and those from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different categories. Of the categories, he found most were used by both sets of dolphins—but eight were only heard from the Irish dolphins. "We are building up a catalogue of the different whistle types they use and trying to associate them with behaviour like foraging, resting, socializing and the communications of groups with calves," project leader Simon Berrow said. "Essentially we are building up what is like a dictionary of words they use or sounds they make." Berrow, a marine biologist, said the dolphins, clicks are used to find their way around and locate prey. The whistles are communications. "They do a whole range of other sounds like barks, groans and a kind of gunshot," he said. "The gunshot is an intense pulse of sound. Sperm whales use it to stun their prey." "When I first heard it I was surprised as I thought sperm whales were the only species who used it. We can speculate the dolphins are using it for the same reason as the sperm whales." Berrow said. References in local legend indicate there have been dolphins in the Shannon estuary for generations and they may even have been resident there as far back as the 6th century. They are regularly seen by passengers on the Shannon ferry and an estimated 25,000 tourists every year take special sightseeing tours on local boats to visit them.

单选题 {{B}}American Sports{{/B}} The United States is a sports-loving nation. Sports in America take a variety of forms: organized competitive struggles, which draw huge crowds to cheer their favorite team to victory; athletic games, played for recreation anywhere sufficient space is found; and hunting and fishing. Most sports are seasonal, so that what is happening in sports depends upon the time of year. Some sports are called spectator sports, as the number of spectators greatly exceeds the number playing in the game. Baseball is the most popular sport in the US. It is played throughout the spring and summer, and professional baseball teams play well into the fall. Although no other game is exactly like baseball, perhaps the one most nearly like it is the English game of cricket. Football is the most popular sport in the fall. The game originated as a college sport more than 75 years ago. It is still played by almost every college and university in the country, and the football stadiums of some of the largest universities seat as many as 80,000 people. The game is not the same as European football or soccer. In American football there are 11 players on each team, and they are dressed in padded uniforms and helmets because the game is rough and injuries are likely to occur. Basketball is the winter sport in American schools and colleges. Like football, basketball originated in the US and is not popular in other countries. Many Americans prefer it to football because it is played indoors throughout the winter and because it is a faster game. It is a very popular game with high schools, and in more than 20 states, state-wide high school matches are held yearly. Other spectator sports include wrestling, boxing, and horse racing. Although horse-racing fans call themselves sportsmen, the accuracy of the term is questionable, as only the jockeys who ride the horse, s in the races can be considered athletes. The so-called sportsmen are the spectators, who do "not assemble" primarily to see the horses race, but to bet upon the outcome of each race. Gambling is the attraction of horse racing.

单选题{{B}}第二篇{{/B}} Valuing Childhood The value of childhood is easily blurred (变得模糊不清) in today's world. Consider some recent developments: The child-murderers in the Jonesboro, Ark. schoolyard shooting case were convicted and sentenced. Two boys, 7 and 8, were charged in the murder of an 11 year old girl in Chicago. Children who commit horrible crimes appear to act of their own will. Yet, as legal proceedings in Jonesboro showed, the one boy who was able to address the court couldn't begin to explain his acts, though he tried to apologize. There may have been a motive-youthful jealousy(妒忌) and resentment. But a deeper question remains:Why did these boys and others in similar trouble apparently lack any inner, moral restraint? That question echoes for the accused in Chicago, young as they are. They wanted the girl's bicycle, a selfish impulse common enough among kids. Redemption (拯救) is a practical necessity. How can value be restored to young lives distorted by acts of violence? The boys in Jonesboro and in Chicago will be confined in institutions for a relatively short time. Despite horror at what was done, children are not-cannot be-dealt with as adults, not if a people wants to consider itself civilized. That's why politicians' cries for adult treatment of youthful criminals ultimately miss the point. But the moral void(真空)that invites violence has many sources. Family instability contributes. So does economic stress. That void, however, can be filled. The work starts with parents, who have to ask themselves whether they're doing enough to give their children a firm sense of right and wrong. Are they really monitoring their activities and their developing processes of thought? Schools, too, have a role in building character. So do youth organizations. So do law enforcement agencies, which can do more to inform the young about laws, their meaning, and their observance (遵守). The goal, ultimately, is to allow all children a normal passage from childhood to adulthood (成年), so that tragic gaps in moral judgement are less likely to occur. The relative few who fill such gaps with acts of violence hint at many others who don't go that far, but who lack the moral foundations childhood should provide-and which progressive human society relies on.
