单选题All over the world, your chances of success in school and life depend more on your family circumstances than on any other factor. By age three, kids with professional parents are already a full year ahead of their poorer peers. They know twice as many words and score 40 points higher on IQ tests. By age 10, the gap is three years. By then, some poor children have not mastered basic reading and math skills, and many never will: this is the age at which failure starts to become irreversible. A few school systems seem to have figured out how to erase these gaps. Finland ensures that every child completes basic education and meets a rigorous standard. One Finnish district official asked about the number of children who don"t complete school in her city, replied, "I can tell you their names if you want." In the United States, KIPP charter schools enroll students from the poorest families and ensure that almost every one of them graduates high school—80 percent make it to college. Singapore narrowed its achievement gap among ethnic minorities from 17 percent to 5 percent over 20 years. These success stories offer lessons for the rest of us. First, get children into school early. High-quality pre-schooling does more for a child"s chances in school and life than any other educational intervention. One study, which began in the 1960s, tracked two groups of students from disadvantaged backgrounds. Some were given the opportunity to attend a high-quality pre-school; others were not. Thirty-five years later, the kids who went to pre-school earned more, had better jobs, and were less likely to have been in prison or divorced. Second, recognize that the average kid spends about half his waking hours up until the age of 15 outside of school—don"t ignore that time. KIPP students spend 60 percent more time in school than the average American students. They arrive earlier, leave later, attend more regularly, and even go to school every other Saturday. Similarly, in 1996, Chile extended its school day to add the equivalent of more than two more years of schooling. Third, pour lots of effort to train teachers. Studies in the United States have shown that kids with the most effective teachers learn three times as much as those with the least effective. Systems such as Singapore"s are choosy about recruiting; they invest in training and continuing education; they evaluate teachers regularly, and they award bonuses only to the top performers. Finally, recognize the value of individualized attention. In Finland, kids who start to struggle receive one-on-one support from their teachers. Roughly one in three Finnish students also gets extra help from a tutor each year. If we can learn the lesson of what works, we can build on it.

单选题To the waitress' relief, the plate was left ______ after being dropped onto the floor.

单选题Parents are often upset when their children praise the homes of their friends and regard it as a slur (诋毁) on their own cooking, or cleaning, or furniture, and often are foolish enough to let the adolescents see that they are annoyed. They may even accuse them of disloyalty, or make some spiteful remark about the friends' parents. Such a loss of dignity and descent into childish behavior on the part of the adults deeply shocks the adolescents, and makes them resolve that in future they will not talk to their parents about the place or people they visit. Before very long the parents will be complaining that the child is so secretive and never tells them anything, but they seldom realize that they have brought this on themselves. Disillusionment with the parents, however good and adequate they may be both as parents and as individuals, is to some degree inevitable. Most children have such a high ideal of their parents, unless the parents themselves have been unsatisfactory, that it can hardly hope to stand up to a realistic evaluation. Parents would be greatly surprised and deeply touched if they realized how much belief their children usually have in their character and infallibility, and how much this faith means to a child. If parents were prepared for this adolescent reaction, and realized that it was a sign that the child was growing up and developing valuable powers of observation and independent judgment, they would not be so hurt, and therefore would not drive the child into opposition by resenting and resisting it. The adolescent, with his passion for sincerity, always respects a parent who admits that he is wrong, or ignorant, or even that he has been unfair or unjust. What the child cannot forgive is the parent's refusal to admit these charges if the child knows them to be true Victorian parents believed that they kept their dignity by retreating behind an unreasoning authoritarian attitude; in fact they did nothing of the kind, but children were then too cowed to let them know how they really felt. Today we tend to go to the other extreme, but on the whole this is a healthier attitude both for the child and the parent. It is always wiser and safer to face up to reality, however painful it may be at the moment.

单选题After attending the spectacular closing ceremony at the Beijing Olympics and feeling the vibrations from hundreds of Chinese drummers pulsating in my own chest, I was tempted to conclude two things: "Holy mackerel, the energy coming out of this country is unrivaled. " And, two: "We are so cooked. Start teaching your kids Mandarin." However, I've learned over the years not to over-interpret any two-week event. Olympics don't change history. They are mere snapshots--a country posing in its Sunday bests for all the world to see. But, as snapshots go, the one China presented through the Olympics was enormously powerful--and it's one that Americans need to reflect upon this election season. China did not build the magnificent $ 43 billion infrastructure for these games, or put on the unparalleled opening and closing ceremonies, simply by the dumb luck of discovering oil. No, it was the culmination of seven years of national investment, planning, concentrated state power, national mobilization and hard work. Seven years... Seven years... Oh, that's right. China was awarded these Olympic Games on July 13, 2001--just two months before 9/11. As I sat in my seat at the Bird's Nest, watching thousands of Chinese dancers, drummers, singers and acrobats on stilts perform their magic at the closing ceremony, I couldn't help but reflect on how China and America have spent the last seven years: China has been preparing for the Olympics; we've been preparing for A1 Qaeda (基地组织). They've been building better stadiums, subways, airports, roads and parks. And we've been building better metal detectors, armored Humvees (悍马车) and pilotless drones. The difference is starting to show. Just compare arriving at La Guardia's dumpy terminal in New York City and driving through the crumbling infrastructure into Manhattan with arriving at Shanghai's sleek airport and taking the 220-mile-per-hour magnetic levitation train, which uses electromagnetic propulsion (推动) instead of steel wheels and tracks, to get to town in a blink. Then ask yourself. Who is living in the third world country? Yes, if you drive an hour out of Beijing, you meet the vast dirt-poor third world of China. But here's what's new. The rich parts of China, the modern parts of Beijing or Shanghai or Dalian, are now more state of the art than rich America. The buildings are architecturally more interesting, the wireless networks more sophisticated, the roads and trains more efficient and nicer. And, I repeat, they did not get all this by discovering oil. They got it by digging inside themselves. I realize the differences. We were attacked on 9/11; they were not. We have real enemies; theirs are small and mostly domestic. We had to respond to 9/11 at least by eliminating the A1 Qaeda base in Afghanistan and investing in tighter homeland security. They could avoid foreign entanglements. Trying to build democracy in Iraq, though, which t supported, was a war of choice and is unlikely to ever produce anything equal to its huge price tag. But the first rule of holes is that when you're in one, stop digging. When you see how much modern infrastructure has been built in China since 2001, under the banner of the Olympics, and you see how much infrastructure has been postponed in America since 2001, under the banner of the war on terrorism, it's clear that the next seven years need to be devoted to nation-building in America. We need to finish our business in Iraq and Afghanistan as quickly as possible, which is why it is a travesty that the Iraqi Parliament has gone on vacation, while 130,000 U. S. troops are standing guard. We can no longer afford to postpone our nation-building while Iraqis squabble over whether to do theirs. A lot of people are now advising Barack Obama to get dirty with John McCain. Sure, fight, fire with fire. That's necessary, but it is not sufficient. Obama got this far because many voters projected onto him that he could be the leader of an American renewal. They know we need nation-building at home now--not in Iraq, not in Afghanistan, not in Georgia, but in America. Obama cannot lose that theme. He cannot let Republicans make this election about who is tough enough to stand up to Russia or bin Laden. It has to be about who is strong enough, focused enough, creative enough and unifying enough to get Americans to rebuild America. The next president can have all the foreign affairs experience in the world, but it will be useless, utterly useless, if we, as a country, are weak. Obama is more right than he knows when he proclaims that this is "our" moment, this is "our" time. But it is our time to get back to work on the only home we have, our time for nation-building in America. I never want to tell my girls—and I'm sure Obama feels the same about his—that they have to go to China to see the future.

单选题 The obvious beauty of symmetry has long been an important consideration to artists and artisans working in the Western tradition. Indeed, there are few examples in Western culture of major structural works such as gates, religious altars, or kings' thrones which do not incorporate the principle of symmetry into their design. The theory underlying this practice rests on certain assumptions about human vision. It is assumed that if the eye of the viewer is directed toward some central point in the design, this central point must be the center of visual gravity as well. In other words, the center of the design must be balanced by equal mass on the left and right. It is further assumed that, if the object is not so arranged, there will arise in the viewer a certain visual discomfort and tension of the eye muscles. This tension and discomfort will, of course, limit the potential for esthetic enjoyment and appreciation. According to the theories which came into vogue at the time of the Renaissance, vertical symmetry is of less significance than bilateral symmetry. In other words, making an esthetic object, small on the top and large at the bottom is not apt to create a visual tension, at least on the scale of an imbalance between right and left. We can see this principle at work in the average gateway arch or cathedral window. There is a wide base with two sides which extend upward. The two sides converge, forming a central design point at the top. This point functions as the center of the design and the center of visual gravity. The artist pays particular attention to the sloping vertical lines. The slope must be exact on both sides. The result of this careful attention is the perfectly formed arch with its two symmetrical shoulders and its central dominating point. It matters little to the artist that the arch design is large at the bottom and increasingly smaller at the top, since he assumes the inherent truth of all Renaissance prescriptions.
