单选题In The Birth Order Book: Why You Are the Way You Are (2004), Dr. Kevin Leman notes that 21 of the first 23 Americans in space were first-born males or only children. More than half of United States presidents have been first-borns or first-born boys. It"s a pretty significant finding historically, because families used to be bigger than they are today. In addition to being high achievers, older children also generally have higher IQs (智商) than younger ones. Researchers have noted that the more kids a family has, the lower each child"s individual IQ tends to be. They give a few reasons for this. Parents only have so much time, attention, and money. The more kids they have, the more these things are divided. First-borns initially get the entire parental-time pie. What"s more, the ratio of grown-ups to kids decreases with each new baby. So the younger ones are surrounded by more children"s language on average than the older kids. Some researchers think parental attention is the key to personality birth-order differences. In his book Born to Rebel , psychologist Frank Sulloway says competition for Mom and Dad"s attention is the thing that really shapes our personalities and, in fact has shaped history. He argues that we adapt our personalities as part of our strategy to seek favor from Mom and Dad. Younger siblings (兄弟姐妹) tend to become rebels. Sulloway studied political activists and found that later-born activists were more radical than their first-born peers. The conclusion of his book is that sibling competition for parental attention can affect society as a whole in times of revolution. Thomas Jefferson, Karl Marx, and Fidel Castro were all younger siblings, for example. As compelling as this all is, it"s also something we should probably take with caution, there are other things that happen to us in life besides the addition of siblings to our families. A parent can die; a hurricane can leave us homeless; we can catch a life-threatening disease. Any one of these things will probably have more of an effect on our personalities than the presence of siblings. A 2002 study bore this out. After interviewing 535 undergraduates, researchers concluded that personality differences related to birth order were "folklore", although IQ and achievement differences were widely supported by research.

单选题Homework has never been terribly popular with students and even many parents, but in recent years it has been particularly scorned. School districts across the country, most recently Los Angeles Unified, are revising their thinking on his educational ritual. Unfortunately, L. A. Unified has produced an inflexible policy which mandates that with the exception of some advanced courses, homework may no longer count for more than 10% of a student"s academic grade. This rule is meant to address the difficulty that students from impoverished or chaotic homes might have in completing their homework. But the policy is unclear and contradictory. Certainly, no homework should be assigned that students cannot do without expensive equipment. But if the district is essentially giving a pass to students who do not do their homework because of complicated family lives, it is going riskily close to the implication that standards need to be lowered for poor children. District administrators say that homework will still be a part of schooling, teachers are allowed to assign as much of it as they want. But with homework counting for no more than 10% of their grades, students can easily skip half their homework and see vey little difference on their report cards. Some students might do well on state tests without completing their homework, but what about the students who performed well on the tests and did their homework? It is quite possible that the homework helped. Yet rather than empowering teachers to find what works best for their students, the policy imposes a flat, across-the-board rule. At the same time, the policy addresses none of the truly thorny questions about homework. If the district finds homework to be unimportant to its students" academic achievement, it should move to reduce or eliminate the assignments, not make them count for almost nothing. Conversely, if homework matters, it should account for a significant portion of the grade. Meanwhile this policy does nothing to ensure that the homework students receive is meaningful or appropriate to their age and the subject, or that teachers are not assigning more than they are willing to review and correct. The homework rules should be put on hold while the school board, which is responsible for setting educational policy, looks into the matter and conducts public hearings. It is not too late for L. A. Unified to do homework right.

单选题The following two questions refer to the following passage: A prestigious private high school has made available to local families a tuition prepayment plan to ease the burden of paying the school's hefty tuition when a student matriculates. The plan allows parents of children under three years old to reserve a spot for their child at the school by making a payment of one-fourth of the current annual tuition for the high school. The parents then make an identical payment every year for the next 15 years, and the student's full four-year tuition is considered paid in full, regardless of how much the regular tuition payments have risen in the intervening years.

单选题 Henric Ibsen, author of the play "A Doll's House", in which a pretty, helpless housewife abandons her husband and children to seek a more serious life, would surely have approved. From January 1st, 2008, all public companies in Norway are obliged to ensure that at least 40% of their board directors are women. Most firms have obeyed the law, which was passed in 2003. But about 75 out of the 480 or so companies it affects are still too male for the government's liking. They will shortly receive a letter informing them that they have until the end of February to act, or face the legal consequences—which could include being dissolved. Before the law was proposed, about 7% of board members in Norway were female, according to the Centre for Corporate Diversity. The number has since jumped to 36%. That is far higher than the average of 9% for big companies across Europe or America's 15% for the Fortune 500. Norway's stock exchange and its main business lobby oppose the law, as do many businessmen. "I am against quotas for women or men as a matter of principle," says Sverre Munck, head of international operations at a media firm. "Board members of public companies should be chosen solely on the basis of merit and experience," he says. Several firms have even given up their public status in order to escape the new law. Companies have had to recruit about 1,000 women in four years. Many complain that it has been difficult to find experienced candidates. Because of this, some of the best women have collected as many as 25-35 directorships each, and are known in Norwegian business circles as the "golden skirts" . One reason for the scarcity is that there are fairly few women in management in Norwegian companies—they occupy around 15% of senior positions. It has been particularly hard for firms in the oil, technology and financial industries to find women with enough experience. Some people worry that their relative lack of experience may keep women quiet on boards, and that in turn could mean that boards might become less able to hold managers to account. Recent history in Norway, however, suggests that the right women can make strong directors. "Women feel more compelled than men to do their homework," says Ms Reksten Skaugen, who was voted Norway's chairman of the year for 2007, "and we can afford to ask the hard questions, because women are not always expected to know the answers."

单选题No step in life is more important than the choice of a vocation. The wise selection of the business, profession, trade, or occupation to which one"s life is to be devoted and the development of full efficiency in the chosen field are matters of the deepest moment to young men and to the public. These vital problems should be solved in a careful, scientific way, with due regard to each person"s aptitudes, abilities, ambitions, resources, and limitations and the relations of these elements to the conditions of success in different industries. If a boy takes up a line of work to which he is adapted, he will achieve far greater success than if he drifts into an industry for which he is not fitted. An occupation out of harmony with the worker"s aptitudes and capacities means inefficiency, unenthusiastic and perhaps distasteful labor, and low pay, while an occupation in harmony with the nature of the man means enthusiasm, love of work, and high economic values—superior product, efficient service, and good pay. If a young man chooses his vocation so that his best abilities and enthusiasms will be united with his daily work, he has laid the foundations of success and happiness. But if his best abilities and enthusiasms are separated from his daily work or do not find in it fair scope and opportunity for exercise and development; if his occupation is merely a means of making a living, and the work he loves to do is sidetracked into the evening hours or pushed out of his life altogether, he will be only a fraction of the man he ought to be. Efficiency and success are largely dependent on adaptation.
