单选题Questions 62 to 66 are based on the following passage. Admit it: at some point in your life, you've been completely obsessed. Obsessed with a particular project perhaps,or a great author,or that hot senior who smiled at you once when you were a fresh'man. Obsession is common and typically harmless, often a powerful motivator and a source of artistic inspiration. Yet its extremes are also feared and reviled, because they form the foundation for obsessive compulsive disorder (OCD) ,a disease that has apparently exploded in prevalence in recent decades. How exactly can we reconcile two conflicting notions of the same phenomenon? Perhaps we can't--but we can glean some insight by taking a closer look at society's complex history with obsession, Lennard J. Davis posits in his new book. Since the 18th century our understanding of obsession has evolved from believing it to be an incurable "madness", thought to afflict a small number of people who were typically poor, to a potentially curable disease afflicting many, including the upper classes. Mental illnesses such as OCD and depression (or at least the tendencies toward them) have practically become a hallmark of passion. This association could partially explain why such illnesses are now so commonly diagnosed, Davis contends since 1970 diagnoses of OCD have increased at least 40-fold. Davis's book also provides biographies of famous artists and psychiatrists with obsessive tendencies. Those who have a purely scientific interest in OCD, however, may find themselves a little bored at times. However, Davis makes several interesting points. For one thing, he says, the difference between OCD and healthy obsession may simply be self-perception. People with OCD feel they are abnormal and wish they could change; obsessive people who do not have OCD--including people with "obsessive-compulsive personality," considered by psychiatrists to be normal--feel just fine. Considering the close relation between OCD and "healthy obsessions" , Davis argues that we tend to draw too strong a line between the healthy and the pathological. Many people have careers tha~ require repetitive-almost obsessive-attention,and most of us heed warnings to take careful precautions in our daily routines to stay healthy and protect ourselves. "We suffer from the manifold requirements of modern life that make us focus on one thing, or many single things," Davis writes. OCD, he explains, is simply a subcategory of what we all do every single day.

单选题As the U.S. finds itself increasingly intertwined with its global partners, keeping alive its commitment to free trade will prove crucial to future expansion. The world owes much of its current prosperity to postwar efforts aimed at dismantling commercial barriers; over the last five years, international trade has led to economic growth, climbing at an average rate of 6.4 percent, compared with a 3.1 percent in world production and consumption. But efforts to open markets further have slowed as many countries have moved to protect endangered industries. The U. S. has been guilty as well, restricting imports of automobiles, steel and textiles. Any rebound in trade deficits may make new protectionist measures hard to resist. While Washington needs outside cooperation to solve economic problems, its enthusiasm for working with other nations has always waxed and waned. The low point was reached during President Reagan's terms, when foreign governments voiced alarm over the over buoyant (增长过快的) dollar and America's budget deficit, the administration shrugged off the complaints with a lecture on supply-side economics. on balance, though, the recent trend has been toward closer consultation among the U. S. arid its principal trading partners, particularly on intervention in world currency markets to stabilize exchange rates. If anything, the importance of multilateral negotiation seems destined to grow as the world's economic geography continues to change. For instance, Japan, already flush with funds, is poised to assume a larger financial role in such global organizations as the World Bank and the International Monetary Fund. And the Maastricht Treaty to integrate the European Union will further reshape the global order. Where America technological know-how and marketing power once dominated world markets, Americans now find themselves jockeying for business amid a throng of muscular new rivals. The U.S. must learn to compete as one among equals or fall behind.

单选题Most publishing is now "electronic" in the sense that books, magazines, and newspapers are prepared on computers, and exist as computer files before they are printed on paper. Often there are advantages to give readers access to the electronic versions of publications as well as, or even instead of, the printed versions. Print publications have lots of advantages. Paper is pleasant to handle, easy to read, and very portable. you can read it almost anywhere. On the other hand, print has its weaknesses. Paper is expensive, and articles are often cut to fit the space available. Printing and distributing paper is expensive and takes time. Printed materials are expensive to store and almost impossible to search. Electronic publishing offers solutions to all these problems. Suppose a publisher makes the electronic copy of a newspaper or magazine available from the net, perhaps on the Internet's World Wide Web. No paper is used and disc space is cheap, so Internet publishing costs very little. Articles don't have to be cut (though there is of course a limit to the amount people are willing to read online). Internet publishing is fast, and readers can access material as soon as it becomes available: within minutes, instead of the next day, next week or next month. Internet publishing goes beyond geographical boundaries: the humblest local paper can be read everywhere from New York to London to Delhi to Tokyo. Delivery costs are low because there are no newsagents to pay, and no postal charges: readers pick up the bills for their on-line sessions. Also, computer-based publications are simple to store (on disc) and every word can be searched electronically. At the moment, newspapers and magazines, TV and radio stations, news agencies and book publishers are making content freely available on the Web because they are competing for "mindshare". Perhaps they want to find out if they can attract and hold an audience online, or perhaps, they're afraid of missing out because "everyone else is doing it". But don't count on things staying that way: Publishers are not in business to lose money.

The Beatles simply put a spark to a fuse(导火线) that was waiting to be lit. Everything changed, and what changed for the Beatles was their lives and their working habits, in the midst of the hysterical(歇斯底里的) following the band attracted. Because of the demand of the fans to see them perform, they played bigger and bigger venues (meeting-places) , especially in America. They played pop music's first "stadium" concert—to 60,000 people in Shea Stadium. But John, Paul, George and Ringo became increasingly unhappy that, because of the screaming of their fans, neither the band nor the audience could hear the music. Creatively frustrated and tired of the pressures of life under siege(围攻) from their fans, they retired from playing concerts in 1966 and decided to concentrate on recording. It was from this point that the brilliance of the Beatles really began to reveal itself: they would record over their career some 200 songs. Never before nor since has any recording and writing group ever developed and yet remained the same in the way the Beatles did. With the aid of the musically wise producer George Martin, the Beatles took their music from the realms of simple sing-along pop songs into sophisticated pieces that set new boundaries for popular music. But at the same time their songs never lost their universal appeal — thanks to the warmth and timelessness of their melodies and lyrics. John and Paul were the major writers in the Beatles, though the skilled musicianship and imagination of George and Ringo meant the band always operated very much as an equal group of individuals. John and Paul were also powerful singers with distinctive styles. It became apparent that, despite the fact that the songwriting credits were always equally attributed to them, Paul and John wrote and sang their own songs. George also contributed two or three of his own compositions to each of the Beatles eleven albums. Even Ringo wrote and sang the occasional song.
