听力原文： The key question for any only child is this: Why were you an only child？ It's a key question for at least two reasons. If your parents had wanted several children, but could have you only, they are most likely to pour into you all the energy and attention that had been intended for several children. I call this the "Special Jewel" phenomenon. Only children, or special jewels often arrive when their parents are older-- usually in their thirties. These special jewels can become very spoiled and serf - centered. On the other hand, you may be an only child be cause your parents planned for only one and stuck to their plan. Your parents may give you a very strict and well-structured education to make you a little adult. Many only children grow up feeling unhappy because they always had to be such little adults. (33) A．Those who are themselves spoiled and self-centered. B．Those who expected to have several children but could only have one. C．Those who like to give expensive jewels to their children. D．Those who give birth to their only children when they are below 30.

The puzzle had to do with waves. Though it might seem intuitive that waves carry water to shore, and sand along with it, it's not that simple. The crest(浪尖)of a passing wave lifts a given hit of water upward and landward, but the ensuing trough(波谷) pushes the water back down and Out to sea. Near the bottom, there the sand is, the water was always assumed to just slide back and forth—and the sand with it. "If you take a very aloof look at a beach," says Inman, "you'll realize that if the two motions move sand back and forth the same amount, then all the sand should end up in deep water.' So for beaches to exist, the crest's onshore flow must somehow move enough sand up the beach to counter the seaward tug of both the trough and gravity . The pressure changes in the sand bed, Inman and Conley think, are the key to beach creation. They found that sand doesn't just slide back and forth with each passing wave. Under a trough, it does slide seaward, in a thin layer just above the bottom. But under a crest its movement is often more elaborate. The higher pressure under a crest—higher because the water is piled higher—forces water into the porous(多孔的) sand. This creates strong whirlpools just above the sand, which help loosen it. As the crest passes overhead, the sand first rushes across the bottom; then it abruptly turns violent lifting off the bottom in large, boiling bunches. Finally, just after the crest passes, the sand explodes up into the great water column. The boiling and rushing move more sand than the backsliding under a trough, so there's a net movement of sand toward the shore. What is the primary purpose of this passage？ A．To explain why sand piles up on the beaches. B．To explain why men only prostrate in the sea. C．To propose a new explanation of a phenomenon. D．To refute a misconception.

A．The Old Man and the Sea B．Moby Dick C．Leaves of Grass D．Robinson Crusoe

The Affluent Society is a modem classic because it helped define a new moment in the human condition. For most of history," hunger, sickness, and cold" threatened nearly everyone, Galbraith wrote. "Poverty was found everywhere in that world. Obviously it is not of ours. "After World War Il, the dread of another Great Depression gave way to an economic boom. In the 1930s unemployment had averaged 18. 2 percent; in the 1950s it was 4. 5 percent. To Galbraith, materialism had gone mad and would breed discontent. Through advertising, companies conditioned consumers to buy things they didn't really want or need. Because so much spending was artificial, it would be unfulfilling. Meanwhile, government spending that would make everyone better off was being cut down because people instinctively-and wrongly-labeled government only as "a necessary evil". It's often said that only the rich are getting ahead; everyone else is standing still or falling behind. Well, there are many undeserving rich--overpaid chief executives, for instance. But over any meaningful period, most people's incomes are increasing. From 1995 to 2004, inflation-adjusted average family income rose 14. 3 percent, to $ 43,200. People feel, "squeezed" because their rising incomes often don't satisfy their rising wants--for bigger homes, more health care, more education, faster Internet connections. The other great frustration is that it has not eliminated insecurity. People regard job stability as part of their standard of living. As corporate layoffs increased, that part has eroded. More workers fear they've be- come "the disposable American" ,as Louis Uchitelle puts it in his book by the same name. Because so much previous suffering and social-conflict stemmed from poverty ,the arrival of widespread affluence suggested utopian(乌托邦式的)possibilities. Up to a point, affluence succeeds. There is much less physical misery than before. People are better off. Unfortunately, affluence also creates new complaints and contradictions. Advanced societies need economic growth to satisfy the multiplying wants of their citizens. But the quest for growth lets loose new anxieties and economic conflicts that disturb the social order. Affluence liberates the individual ,promising that everyone can choose a unique way to self-fulfillment. But the promise is so extravagant that it predestines many disappointments and sometimes inspires choices that have anti-social consequences, including family breakdown and obesity (肥胖症). Statistical indicators of happiness have not risen with incomes. Should we be surprised？ Not really. We've simply reaffirmed an old truth: the pursuit of affluence does not always end with happiness. What question does John Kenneth Galbraith raise in his book The Affluent Society？ A．Why statistics don't tell the truth about the economy. B．Why affluence doesn't guarantee happiness. C．How happiness can be promoted today. D．What lies behind an economic boom.
