(1) Educating girls quite possibly outputs a higher rate of return than any other investment available in the developing world. Women’s education may be unusual territory for economists but enhancing women’s contribution to development is actually as much an economic as a social issue. And economics with its emphasis on incentives (激励), provides guideposts that point to an explanation for why so many girls are deprived of an education.Parents in low-income countries fall to invest in their daughters because they do not expect them to make an economic contribution to the family girls grow up only to many into somebody else's family and bear children. (2) Girls are thus seen as less valuable than boys and are kept at home to do housework while their broths are sent to school—the prophecy (预言) becomes self-fulfilling tapping women in vicious circle (恶性循环) of neglect.(3) An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children, ensuring that her daughters are given a fair chance. (4) The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys, will be educated and healthy. The vicious circle is thus transformed into a virtuous circle.(5) Few will dispute that educating women has great social benefits. But it has enormous economic advantages as well. Most obviously, there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 percent for each additional year of schooling. Such big returns are impressive by the standard of other available investments, but they are just the beginning. Educating women also has a significant impact on health practices, including family planning.

Technology is a two-edged sword. Rarely is this as clear as it is in the realm of health care. Technology allows doctors to test their patients for genetic defects—and then to turn around and spread the results throughout the world via the Internet. (1) For someone in need of treatment, that’s good news. But for someone in search of a job or an insurance policy, the tidings can be all bad.Last week a corollary (推论) to the patients bill of rights now before Congress: a right to medical privacy. Beginning in 2002, under rules set to become law in February, patients would be able to stipulate the conditions under which their personal medical data could be divulged. They would be able to examine their records and make corrections. They could learn who else had seen the information. (2) Improper use of records by a caregiver or insurer could result in both civil and criminal penalties. The plan was said to be an unprecedented step toward putting Americans back in control of their own medical records.(3) While the administration billed the rules as an attempt to strike a balance between the needs of consumers and those of the health-care industry, neither doctors nor insurance companies were happy. The doctors said the rules could actually erode privacy, pointing to a provision allowing managed-care plans to use personal information without consent if the purpose was “health-care operations”. That, physicians said, was a loophole (漏洞) through which Health Maintenance Organizations and other insurers could pry (窥探) into the doctor-patient relationship, in the name of assessing the quality of care. Meanwhile, the insurers protested that the rules would make them vulnerable to lawsuits.They were especially disturbed by a provision holding them liable for privacy breaches (违背) by “business partners” such as lawyers and accountants. Both groups agreed that privacy protections would drive up the cost of health care by at least an additional $3.8 billion, and maybe much more, over the next five years. (4) They also complained about the increased level of federal scrutiny required by the new rules’ enforcement rules.One aim of the rules is to reassure patients about confidentiality, thereby encouraging them to be open with their doctors. (5) Today various cancers and sexually transmitted diseases can go untreated because patients are afraid of embarrassment or of losing insurance coverage. The fear is real: an official noted that a January poll by Princeton Survey Research Associates found that one in six U.S. adults had at some time done something unusual to conceal medical information, such as paying cash for services.

Nobody likes taxes.Now that’s a fairly safe statement to make. I know I don’t. One of the reasons I moved back to the US from Canada, is that Americans pay far fewer taxes than Canadians do. In fact, it seems to be part of the American dream to avoid paying any taxes. We don’t want to pay them on the Internet. Many states don’t want their citizens to pay state taxes. And a huge federal income tax cut was just pushed through.And no doubt there are still people who think we pay too many taxes. But the people of Braintree, Massachusetts, might be thinking differently. Braintree has a problem. Not once in the past two decades did the town pass resolutions that ignored Proposition 2.5—the law that says the town government cannot raise each year’s tax levy more than 2.5 percent above the previous year’s charges. Nor did they float any bonds to pay for debt. Braintree is also a fairly bustling commercial town. Which mean that resident tax rates were among the lowest in the Boston area.But there’s one problem. Braintree is, well, falling apart. Especially its schools. While everybody was patting himself or herself on the back for keeping taxes down, school, roads, bridges and the like were growing older and weren’t receiving the attention they needed. But even if they did get the attention, not much could be done because there wasn’t enough money in the town’s kitty to pay for needed repair. But as my mother would say, one can only ignore the elephant in the living room for so long. And now it’s time to pay up. The school department wants $100 million to fix the schools. Millions more will be needed for road repairs and fixing the town’s worsening water and sewer lines.Boy, oh boy, people are going to have SOME kind of tax bill in Braintree this year. And probably for the next few years as well. And don’t forget, this situation affects more than just the town’s infrastructure. Real estate prices will suffer as well. Who wants to move to a town with falling schools, bad roads, and questionable water?There is a lesson in all this—not paying enough tax is just as bad as paying too much tax. There are some people in the US who point out that all tax money should be given back to individuals, not the various branches of government. It’s our money, they cry. In one way, agree with them, it is our money. But the fact they conveniently forget—or ignore—is that the money the government keeps is “our” money as well. That’s because it pays for OUR schools, OUR roads, OUR military, OUR communities in need of help after events like floods or other disasters.1. In what way might people of Braintree think different about paying taxes?2. What makes the author come to the conclusion that people in Braintree pay the lowest tax rates in the Boston area is the fact that ________.3. What is the alleged problem that faces Braintree at present?4. When the author quotes from his mother that “one can only ignore the elephant in the living room for so long” (the fourth paragraph), he means that ________.5. With regard to paying taxes, the author is actually saying that ________.

Although language is used to transmit information, the informative functions of language are fused with older and deeper functions so that only a small portion of our everyday speech can be described as purely informative. The ability to use language for strictly informative purposes was probably developed relatively late in the course of linguistic evolution.Long before that time, our ancestral species probably made the sorts of cries animals do to express feelings of hunger, fear, loneliness, and the like. Gradually these noises seem to have become more differentiated, transforming the cries into language as we know it today.Although we have developed language in which accurate reports may be given, we still use language as vocal equivalents of gestures such as crying in pain. When words are used as the vocal equivalent of expressive gestures, language is functioning in presymbolic ways. These presymbolic uses of language coexist our symbolic system so that the talking we do in everyday life is a thorough blending of symbolic and presymbolic language.What we call social conversation is mainly presymbolic in character. When we are at a large social gathering, for example, we all have to talk. It is typical of these conversations that, except among very good friends, few of the remarks made have any informative value: talk together about nothing at all and thereby establishes a relationship.There is principle at work in the selection of the subject matter we deem appropriate for social conversation. Since the purpose of this kind of talk is the establishment of communion, we are careful to select subjects about which agreement is immediately possible. With each new agreement, no matter how commonplace, the fear and suspicion of the stranger wear away, and the possibility of friendship emerges. When further conversation reveals that we have friends or political views or artistic values or hobbies in common, a friend is made, and genuine communication and cooperation can begin.1. The phrase “older and deeper functions” in the first sentence refers to ________.2. The author uses the term “presymbolic language” to mean probably ________.3. With regard to the evolution of language, which of the following statements is TRUE?4. The primary value of presymbolic language for humans is that it ________.5. Which of the following statements is TRUE according to the passage?
