单选题Sex prejudices are based on and justified by the ideology that biology is destiny. According to this ideology, basic biological and psychological differences exist between the sexes. These differences require each sex to play a separate role in social life. Women are the weaker sex both physically and emotionally. Thus, they are naturally suited, much more so than men, to the performance of domestic duties. A woman"s place, under normal circumstances, is within the protective environment of the home. Nature has determined that women play caretaker roles, such as wife and mother and homemaker. On the other hand，men are best suited to go out into the competitive world of work and politics, where serious responsibilities must be taken on. Men are to be the providers; women and children are "dependents". The ideology also holds that women who wish to work outside the household should naturally fill these jobs that are in line with the special capabilities of their sex. It is thus appropriate for women, not men, to be employed as nurses, social workers, elementary school teachers, household helpers, and clerks and secretaries. These positions are simply an extension of women"s domestic role. Informal distinctions between "women"s work" and "men"s work" in the labor force, according to the ideology, are simply a functional reflection of the basic differences between the sexes. Finally, the ideology suggests that nature has worked her will in another significant way. For the human species to survive over time, its members must regularly reproduce. Thus, women must, whether at home or in the labor force, make the most of their physical appearance. So goes the ideology. It is, of course, not true that basic biological and psychological differences between the sexes require each to play sex-defined roles in social life. There is ample evidence that sex roles vary from society to society, and those role differences that to exist are largely learned. But to the degree people actually believe that biology is destiny and that nature intended for men and women to make different contributions to society, sex-defined roles will be seen as totally acceptable.

单选题Today, a high-level finance manager is just as likely to be a casual-looking 21-year-old as a balding executive. They have all either started their own companies or head a division within an existing firm. Most are under 30. Many of them share a tendency to think, speak and act fast. A detailed psychological study carried out recently on young business start-uppers aged over 25 revealed some common characteristics. The head psychologist at the University of Northumbria, Dr. Martyn Dyer-Smith, says "We found that they are opportunists. They have that entrepreneurial ability to take whatever is in front of them and turn it to their advantage. Any fool can make US $ 2 if they are in the right place at the right time, what is much harder is to actually plan their business. Originally I had a hypothesis that they planned a long time ahead, but I was wrong. What came across was a surprisingly short planning time. They took the opportunities as and when they came up." What cannot be underestimated, though, is self-confidence. "There is an amazing, almost abnormal, belief in themselves and (they) go very much on intuition." Says Dyer-Smith. While there is no typical pattern to what puts someone in the fast lane, there are some common threads: living up to the expectations of parents, channeling excessive amounts of energy into business, or finding a way to overcome personal barriers such as dyslexia (a reading disability) or learning difficulties, for example. The biggest surprise was the lack of young women. This was particularly unexpected, given the recent publicity about how girls are performing better than boys at school and becoming more confident and ambitious. But young women are opting for more secure careers rather than gambling with their future. With only a handful of female role models, some girls are not even considering being their own boss, let alone working on a concept fresh out of school, according to Dr Susan Vinnicombe, director of the center for the Development of Women Business Leader. "Women are going more into the corporate structure and doing well there. But perhaps the reason that they are not doing business for themselves at an earlier age is because women's attitudes are different. They perceive risk in a different way to men, who are not worried about borrowing huge amounts of money if it's going to help their business in the long term. Women are more cautious and more hesitant ," she says. Vinnicombe sees the lack of female entrepreneurs as part of a larger problem about women and the IT industry. Given that the computer world is one of the key areas for growth, where youth is an asset, it is "remarkable" that so many women are missing out on it. "The number of women in IT has actually dropped in the past 10 years. There is a real problem with attracting them to the IT industry, as girls don't seem to want to do it at university. It's become such a worrying issue that I know the government is looking into ways to attract them./

单选题Opponents of affirmative action say the battle over the use of race in college admissions is hardly over, despite the Supreme Court"s ruling Monday upholding the goal of a diverse student body. Higher education leaders overwhelmingly hailed the decision, saying it reaffirmed policies used by most .selective colleges and universities. But some critics raised the possibility of more lawsuits, and promised to continue pressuring the Department of Education"s Office of Civil Rights to investigate questionable policies. "We"re talking about admission programs, scholarships, any program only for minorities or in which the standards used to judge admissions are substantially different," says Linda Chavez, founder and president of the Center for Equal Opportunity, a conservative non-profit group. Others say they"ll take their case to voters. "We have to seriously contest all this at the ballot box," says University of California regent Ward Connerly, who helped win voter approval of California"s Proposition 209, which prohibits considering race or gender in public education, hiring and contracting. Because of that law, Monday"s ruling had no practical impact in the state. "It may be time for us to let the (Michigan) voters decide if they want to use race as a factor in admissions," Connerly said Monday. Meanwhile, U. S. Education Secretary Rod Paige, consistent with President Bushes stance opposing affirmative action, said the Department of Education will "continue examining and highlighting effective race-neutral approaches to ensure broad access to and diversity within our public institutions". Even Supreme Court Justice Sandra Day O"Connor, in one of the opinions, recommended that states look for lessons in race-neutral programs being tried in California and elsewhere. While the ruling said admission officials may consider race in the selection process, colleges and universities are not obligated to do so. "Ultimately in the debate, diversity is a choice, not a legal mandate", says Arthur Coleman, a former Department of Education official who now helps colleges and universities ensure constitutional policies. The public, too, remains conflicted, largely along racial lines. According to a January poll by the non-profit research organization Public Agenda, 79% of Americans said it is important for colleges to have a racially diverse student body, while just 54% said affirmative action programs should continue. In a Gallup poll conducted days before the ruling, 49% of adults said they favor affirmative action and 43% did not, with blacks and Hispanics far more likely to favor the practice than whites. And some educators doubt that with Monday"s ruling, those opposing affirmative action will change their minds. For now, admission officials and university lawyers are poring over the ruling to determine how or whether to adjust policies. While most tend to be closed-mouthed about admission policies, many say they don"t expect significant changes.
