单选题Aids in South Africa is threatening to become a problem. At the end of 1993, 4.25% of South African adults were HIV positive. By the end of 1994, the figure was 7.57%. This increase in a year is the largest for the spread of the virus in Africa and possibly the world, and it seems certain that 12% or more of the population will be HIV positive by Christmas. In the worst hit area, the HIV positive rate now tops 20%. It seems South Africa is moving rapidly towards the catastrophic 35% levels of infection in East Africa. This will be the first time that the virus will have become so widespread in a sophisticated, industrialized country. Both the present and preceding governments should bear responsibility; each was aware of the crisis and did almost nothing. There is no public campaign to promote safe sex, for example. The apartheid regime was too conscious of religious sensitivities to organize an explicit anti-Aids campaign, and the African National Congress is far too nervous about traditional African attitudes to sex. A survey of black women in Johannesburg revealed that 75% were willing to accept condoms if they could persuade their partners to use them, but that in practice only 2% had managed to do so. Women are the chief victims with the highest HIV-positive rates among nurses and teachers. Many African men have responded to the epidemic by choosing younger and younger partners. There is even a myth that sex with a young enough girl can cure an Aids-stricken male. Inevitably young women are the hardest hit, a phenomenon compounded by the high incidence of rape. More than 100 rapes are reported to the authorities every day, although this figure is believed to represent a minority of actual cases. Despite the spread of the virus, the statistics manage to struggle on to only about page six of most South African newspapers because the crisis is still in "phoney war" stage —although there are more than 1.8 million HIV-positive South Africans, relatively few of them have developed Aids. Doctors say the virus seems to be taking longer to move through its cycle here, perhaps because South Africans with their higher standards of living, are healthier and therefore more resistant than people further north in Africa. Without doubt, the present air of complacency will vanish as soon as high profile members of the elite begin to be affected and the implications for the economy sink in. Moreover, the spread of the virus may greatly damage the present racial reconciliation in South Africa, since Aids is now overwhelmingly a disease of blacks, and many whites are beginning to see almost every African as an Aids risk.

单选题Having a few too many drinks can mean more than just a blackout or a bad hangover. People who engage in binge drinking are courting danger, experts warn. Binge drinking is most common at colleges and universities, where many adults treat drinking to excess as a rite of passage. A 1997 study from the Harvard School of Public Health reports that 42.7% of all college students engage in binge drinking. The well-publicized deaths of several college students from binge drinking in 1997 highlights the risks. An 18-year-old freshman at the Massachusetts Institute of Technology drank himself into a coma and died. A 20-year-old fraternity pledge at Louisiana State University died from alcohol poisoning. "Alcohol is always toxic. It"s really a poison," said Steven Schandler, professor of psychology at Chapman University and chief of addiction research at the Long Beach Veterans Affairs Health Care System, who added that binge drinking can lead to alcohol poisoning. "Because it"s a poison, like any other poison, if you take in a little bit, you might tolerate it, but if you take in a lot, you might die." Administrators and doctors say that college freshmen are especially at risk for alcohol poisoning, in part because they often lack the maturity to refrain or stop. And for some who may be new to drinking, their bodies have a relatively low tolerance for alcohol. But problems with alcohol aren"t limited to teenagers and young adults. A 39-year-old Buena Park man recently recalled that two days of steady imbibing on a trip to Las Vegas several years ago left him in bad shape. Doctors say blood alcohol levels of about 4%—five times the legal intoxication limit of 0.8%—can induce potentially lethal side effects in most people. Alcoholics have higher limits. Although not well understood, enzymes that break down and expel alcohol in the liver and kidneys do so more effectively in seasoned drinkers, allowing them to tolerate more, Schandler said. Regardless of a person"s tolerance, alcohol exerts its influence when the amount of alcohol taken in exceeds the amount that the body can digest. At that point, alcohol passes from the bloodstream into the brain and begins its attack. Alcohol first affects the brain"s cortex, which controls more sophisticated thought processes. That"s why people generally become less inhibited under the influence of alcohol, and some are more willing to try things that could be dangerous to themselves or others. Coordination, mainly controlled by the cerebellum, is the next to go, leading to slurred speech and difficulty walking in a straight line. As excessive drinking continues, alcohol moves deeper into the brain until "it gets to the very basic structure of the brain stem that affects things like respiration and heart beat," said Dr. Bret Ginther, an assistant clinical professor of emergency medicine at UC Irvine. At that point, people may pass out or fall into a coma. Their vital signs may weaken. "The most common cause of death from alcohol poisoning is respiratory arrest," said Ginther. Eventually, the heart simply stops. Getting to that point is fairly unusual. But Ginther said that at least once or twice a month, patients are brought into the emergency room at UCI Medical Center in Orange suffering from alcohol poisoning. College officials say they are always on the lookout for alcohol abuse but say there is no fail-safe method to keep students from drinking. Many colleges try to educate students, especially those caught drinking illegally or causing disruptions. The Higher Education Center for Alcohol and Other Drug Prevention in Newton, Mass, advocates a community-based approach that includes administrators, faculty, police and businesses in the fight to curb binge drinking, in part by being on alert for people abusing alcohol. The center also stresses the importance of parental guidance and urges parents to have frank discussions with their children about excessive drinking.

单选题 Prices determine how resources are to be used. They are also the means by which products and services that are in limited supply are rationed among buyers. The price system of the United States is a very complex network composed of the prices of all the products bought and sold in the economy as well as those of a myriad of services, including labor, professional, transportation, and public-utility services. The interrelationships of all these prices make up the "system" of prices. The price of any particular product or service is linked to a broad, complicated system of prices in which everything seems to depend more or less upon everything else. If one were to ask a group of randomly selected individuals to define "price", many would reply that price is an amount of money paid by the buyer to the seller of a product or service or, in other words, that price is the money value of a product or service as agreed upon in a market transaction. This definition is, of course, valid as far as it goes. For a complete understanding of a price in any particular transaction, much more than the amount of money involved must be known. Both the buyer anti the seller should be familiar with not only the money amount, but with the amount and quality of the product or service to be exchanged, the time and place at which the exchange will take place and payment will be made, the form of money to be used, the credit terms and discounts that apply to the transaction, guarantees on the product or service, delivery terms, return privileges, and other factors. In other words, both buyer and seller should be fully aware of all the factors that comprise the total "package" being exchanged for the asked-for amount of money in order that they may evaluate a given price.

单选题On February 10, the world of psychiatry will be asked, metaphorically, to lie on the couch and answer questions about the state it thinks it is in. For that is the day the American Psychiatric Association (APA) plans to release a draft of the fifth version of its Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Mental illness carrying such stigma (~) as it does, and the brain being as little-understood as it is, revising the DSM is always a controversial undertaking. This time, however, some of the questions asked of the process are likely to be particularly probing. The DSM, the first version of which was published in 1952, lists recognized psychological disorders and the symptoms used to diagnose them. In the United States, what is in it influences whether someone will be diagnosed with an illness at all, how he will be treated if he is so diagnosed, and whether his insurance company will pay for that treatment. Researchers in other countries generally defer to the DSM, too, making the manual"s definitions a lingua franca for the science of medical psychology. And, perhaps most profoundly, the DSM, then, is an important document. The APA has been working on the latest revision since 1999, and will not release the final version until May 2013. But some people are already accusing it of excessive secrecy and being too ambitious about the changes it proposes. Those critics will be picking over the draft next week to see if their fears have been realized. The original DSM reflected the "psychodynamic" view of mental illness, in which problems were thought to result from an interplay between personality and life history. (Think Freud, Jung and long hours recounting your childhood and dreams.) The third version, which was published in 1980, took a more medical approach. Mental illnesses were seen as distinct and classifiable, like physical diseases. DSM-Ⅲ came with checklists of symptoms that allowed straightforward, unambiguous diagnosis. Psychiatry began to seem less like an art form and more like a science. DSM-Ⅲ also introduced many more diagnoses than had appeared before. These included attention-deficit disorder, post-traumatic stress disorder and social phobia. In fact, the number of specific diagnoses more than doubled between DSM-Ⅰ and DSM-Ⅲ, from 106 to 265. DSM-IV, published in 1994, increased the number to 267, but left the underlying model alone.

单选题Painter Frida Kahlo (1910-1954) often used harrowing images derived from her Mexican heritage to express suffering caused by a disabling accident and a stormy marriage. Suggesting much personal and emotional content, her works—many of them self-portraits—have been exhaustively psychoanalyzed, while their political content has been less studied. Yet Kahlo was an ardent political activist who in her art sought not only to explore her own roots, but also to champion Mexico"s struggle for an independent political and cultural identity. Kahlo was influenced by Marxism, which appealed to many intellectuals in the 1920s and 1930s, and by Mexican nationalism. Interest in Mexico"s culture and history had revived in the nineteenth century, and by the early 1900s, Mexican indigenista tendencies ranged from a violently anti-Spanish idealization of Aztec Mexico to an emphasis on contemporary Mexican Indians as the key to authentic Mexican culture. Mexican nationalism, reacting against contemporary United States political intervention in labor disputes as well as against past domination by Spain, identified the Aztecs as the last independent rulers of an indigenous political unit. Kahlo"s form of Mexicanidad, a romantic nationalism that focused upon traditional art uniting all indigenistas, revered the Aztecs as a powerful pre-Columbian society that had united a large area of the Middle Americas and that was thought to have been based on communal labor, the Marxist ideal. In her paintings, Kahlo repeatedly employed Aztec symbols, such as skeletons or bleeding hearts that were traditionally related to the emanation of life from death and light from darkness. These images of destruction coupled with creation speak not only to Kahlo"s personal battle for life, but also to the Mexican struggle to emerge as a nation—by implication, to emerge with the political and cultural strength admired in the Aztec civilization. Self-portrait on the Border between Mexico and the United States 1932. , for example, shows Kahlo wearing a bone necklace, holding a Mexican flag, and standing between a highly industrialized United States and an agricultural, preindustrial Mexico. On the United States side are mechanistic and modem images such as smokestacks, light bulbs, and robots. In contrast, the organic and ancient symbols on the Mexican side—a blood-drenched Sun, lush vegetation, an Aztec sculpture, a pre-Columbian temple, and a skull alluding to those that lined the walls of Aztec temples—emphasize the interrelation of life, death, the earth, and the cosmos. Kahlo portrayed Aztec images in the folkloric style of traditional Mexican paintings, thereby heightening the clash between modem materialism and indigenous tradition; similarly, she favored planned economic development, but not at the expense of cultural identity. Her use of familiar symbols in a readily accessible style also served her goal of being popularly understood; in turn, Kahlo is viewed by some Mexicans as a mythic figure representative of nationalism itself.

单选题During the normal development of self, a child is affected by certain influential factors. 1 infants form an attachment with the mother that must undergo a process of separation and individuation. Object relations psychology examines this relationship, which depends on the ability of the child to separate himself from his object, the mother, and realize that he is a separate individual. 2 Certainly, affectionate, caring parents are essential as well. As the child begins to develop his sense of self, he must master certain developmental tasks that are part of growing up, such as acquisition of language and toilet training. 3 4 Since an infant"s relationship with his mother is so important, according to many psychologists, what effect does being separated from the biological mother have on the adopted child? 5 But what about a child who is older when he is adopted? 6 When he is placed with an adoptive family, he is likely to experience separation anxiety from his foster mother, who can be regarded as symbolically abandoning him as his own biological mother did. 7 Now it seems as though he has to start over; his protesting may give way to despair as he yearns for people who used to be in his life. The adoptive family should offer as much affection and security as possible to reassure the child that he is safe, that they are reliable sources of loving care, and that they will help him through this difficult stage. 8 Although he may not mind the actual separation from his mother when he goes to playschool or day care, he may become obsessed about the time when his mother is supposed to pick him up at day care or kindergarten; tardiness may provoke fears about car accidents or death. On the other hand, some psychologists believe that a child who is given more affection is sometimes more strongly attached to their parents and therefore more prone to separation anxiety than are some of those who are treated more roughly. 9 On the contrary, the capacity to experience separation anxiety can be regarded as a sign of the healthy personality. 10 [A] A safe, loving environment is another necessary component for the development of a healthy self-concept. [B] For infants adopted at birth, the effect may be minimal, for the infant has often had no opportunity to bond with the biological mother. [C] Since such "dependence" in the well-loved child is outgrown and later provides the basis for a stable independence, it would be a mistake to suppose it to be pathological. [D] One of the most important involves his relationship with his mother. [E] What, then, effect does adoption have on the development of a healthy sense of sel~ [F] His transition to living in an adoptive home may be difficult as he adjusts to new surroundings and caregivers because, by the age of 18 months, he has already begun to develop a sense of self in relation to others. [G] Despite these actions, sometimes a child may continue to suffer from separation anxiety. [H] Anything that interrupts the development of these important skills may interfere with developing a healthy self-concept. [I] Consider a toddler adopted at the age of 18 months who has lived in the same foster home since birth. [J] An adopted child, then, has at least an average chance of successful individuation, assuming he is adopted by loving parents.
