单选题The years between 1870 and 1895 brought enormous changes to the theater in the United States as the resident company was undermined by touring groups, as New York became the only major center of production, and as the long run replaced the repertory(库存)system. By 1870, the resident stock company was at the peak of its development in the United States. The 50 permanent companies of 1870, however, had dwindled to 20 by 1878, to 8 by 1880, to 4 by 1887, and had almost disappeared by 1900. While the causes of this change are numerous, probably the most important was the rise of the "combination" company(that is, one that travels with stars and full company). Sending out a complete production was merely a logical extension of touring by stars. By the 1840's many major actors were already taking along a small group of lesser players, for they could not be sure that local companies could supply adequate support in secondary roles. There is much disagreement about the origin of the combination company. Bouciault claimed to have initiated it around 1860 when he sent out a troupe with Colleen Bawn, but a book published in 1859 speaks of combination companies as already established. Joseph Jefferson HI also declared that he was a pioneer in the movement. In actuality, the practice probably began tentatively during the 1850's, only to be interrupted by the Civil War. It mushroomed in the 1870's, as the rapid expansion of the railway system made it increasingly feasible to transport full productions. In 1872, Lawrence Barrett took his company, but no scenery, on tour; in 1876, Rose Michel was sent out with full company, scenery, and properties. By the season of 1876—1877 there were nearly 100 combination companies on the road, and by 1886 there were 282.

单选题NASA launched the first space mission to Pluto yesterday as a powerful rocket hurled the New Horizons spacecraft on a nine-year, three-billion-mile journey to the edge of the solar system As it soared toward a 2007 meeting with Jupiter, whose powerful gravitational field will shoot it on its way to Pluto. mission managers said radio communications confirmed that the 1,054-pound craft was in good health. The $700 million mission began when a Lockheed Martin Atlas 5 rocket rose from a launching pad at the Cape Canaveral Air Force Station in Florida at 2 p.m., almost an hour later than planned because of low clouds that obscured a clear view of the flight path by tracking cameras. Less than an hour later, all three stages of the booster rocket worked as planned, and the spacecraft separated from them and sprinted away toward deep space. The robot ship sped away at about 36,000 miles per hour, the fastest flight of any spacecraft sent from Earth. allowing it to pass the Moon in about nine hours. "This is a historic day," said Alan Stem of the Southwest Research Institute in Boulder, Colo, the mission's principal scientist and team leader. Speaking at a news conference at the Kennedy Space Center in Florida. Dr. Stern said the timing assured that the New Horizons would arrive for its closest approach to Pluto on July 14, 2015—the 50th anniversary of the first flyby of Mars by the Mariner 4. the mission that began the exploration of the planets. The New Horizons is powered by a small plutonium-fired electric generator. Its instruments include three cameras, for visible-light, infrared and ultraviolet images, and three spectrometers to study the composition and temperatures of Pluto's thin atmosphere and surface features. It also carries a University of Colorado dust counter, the first experiment to fly on a planetary mission that is entirely designed and operated by students. This is the only experiment that will not hibernate during the mission. Yesterday's liftoff also paid regard to Pluto's discoverer, the astronomer Clyde W. Tombaugh. who in 1930 became the only American to find a planet in the solar system.(He died at 90. in 1997.) His widow, Patricia Tombaugh. 93. and other family members were present at the cape, and some of his remains were among the commemorative items aboard the spacecraft. "Some of Clyde's ashes are on their way to Pluto today," Dr. Stem said. The New Horizons is to reach Jupiter's gravitational field in 13 months. The trip to Pluto will take eight more years, most of which the craft will spend in electronic "hibernation" to save power and wear on the equipment needed for its seven experiments. In addition to the two-hour delay, the launching was postponed twice in two days—on Tuesday by strong winds at the cape and on Wednesday by a storm that caused a power; failure at the spacecraft's control center at the Johns Hopkins University Applied Physics Laboratory in Laurel. Md. Mission planners had until Feb. 14 to launch the mission this year, but only until the end of this month to use the gravity boost from Jupiter, which will shorten the trip to Pluto by five years.

单选题{{B}}Passage Three{{/B}} An ethics crisis at one of the world's most successful human embryonic stem cell laboratories has plunged the controversial field of research into a new swirl of uncertainty. The accusations surrounding Korean cloning expert Woo Suk Hwang of Seoul National University--the first scientist to grow stem cells inside cloned human embryos--has already killed a spate of planned studies that sought to prove the cells' medical potential. The claims that Hwang may have obtained human eggs for his studies from women who felt pressured to donate are also reigniting a long-smoldering debate in the United States over the ethics of paying young women for their eggs, which are difficult to obtain but essential to the production of stem cells tailored to individuals. Egg donation, which is generally safe but occasionally leads to serious and even life-threatening complications, has been a wedge issue in the stem cell debates, linking feminists and other liberal thinkers to conservatives who favor tighter limits on stem cell research. "We're in danger of making women into guinea pigs for this research even before there are any treatments to be tested," said Marcy Darnovsky, associate director of the Center for Genetics and Society in Oakland, Calif. "We really need clear rules that someone is enforcing." With current techniques, it takes dozens of eggs to make a single cloned human embryo, which is destroyed in the process of extracting the stem cells. That means that if the field of therapeutic cloning is to advance--a field involving the creation of cloned embryos as sources of stem cells that would be genetically matched to particular patients--a significant number of eggs will be needed both to fuel the initial research and eventually to satisfy the demands of patients. Scientists at Advanced Cell Technology of Worcester, Mass. , made the decision to pay women only after a long analysis by an ethics board created by the company, said scientific director Robert Lanza. He still thinks it is the right way to go, Lanza said, given the painful injections involved, the uncomfortable egg suction procedure, and the approximately 5 percent chance of a serious case of hormonal over-stimulation, which can require hospitalization. Others say such payments cannot help but be coercive, especially for poor women who might feel compelled to take on those risks just to make ends meet. In April, the National Academies, chartered by Congress to advise the nation on matters of science, released a report that recommended against payments for human eggs beyond expenses incurred by the donors, in part because of the "sensitivities" inherent in the creation of embryos destined for destruction. But the report's impact remains uncertain as research institutions, fertility clinics and the biggest wild card of them all--Congress--mull the Academies' findings.

单选题Richard Satava, program manager for advanced medical technologies, has been a driving force bringing virtual reality to medicine, where computers create a "virtual" or simulated environment for surgeons and others medical practitioners (从业者). "With virtual reality we'll be able to put a surgeon in every trench," said Satava. He envisaged a time when soldiers who are wounded fighting overseas are put in mobile surgical units equipped with computers. The computers would transmit images of the soldiers to surgeons back in the U. S. The surgeons would look at the soldier through virtual reality helmets (头盔) that contain a small screen displaying the image of the wound. The doctors would guide robotic instruments in the battlefield mobile surgical unit that operate on the soldier. Although Satava's vision may be years away from standard operating procedure, scientists are progressing toward virtual reality surgery. Engineers at an international organization in California are developing a tele-operating device. As surgeons watch a three-dimensional image of the surgery, they move instruments that are connected to a computer, which passes their movements to robotic instruments that perform the surgery. The computer provides feedback to the surgeon on force, textures, and sound. These technological wonders may not yet be part of the community hospital setting but increasingly some of the machinery is finding its way into civilian medicine. At Wayne State University Medical School, surgeon Lucia Zamorano takes images of the brain from computerized scans and uses a computer program to produce a 3-D image. She can then maneuver the 3-D image on the computer screen to map the shortest, least invasive surgical path to the tumor (肿瘤). Zamorano is also using technology that attaches a probe to surgical instruments so that she can track their positions. While cutting away a tumor deep in the brain, she watches the movement of her surgical tools in a computer graphics image of the patient's brain taken before surgery. During these procedures--operations that are done through small cuts in the body in which a miniature camera and surgical tools are maneuvered--surgeons are wearing 3-D glasses for a better view. And they are commanding robot surgeons to cut away tissue more accurately than human surgeons can. Satava says, "We are in the midst of a fundamental change in the field of medicine. /

单选题Sadness isn't manly—this Eric Weaver knew. When depression engulfed this New York police sergeant, it took a different guise: a near-constant state of anger. "One minute I'd be okay and the next minute I'd be screaming at my kids and punching the wall," he recalls. "My kids would ask, 'What's wrong with Daddy? Why's he so mad all the time?'" For years, Weaver didn't know what was wrong. Weaver's confusion about what tortured him was not unusual. Roughly a third of the 18 million or more Americans who suffer depression each year are men. Yet all too often, experts say, men fail to recognize the symptoms and get the treatment they need. For years, experts suspected that gender makes a big difference in depression. Studies from New York to New Zealand have repeatedly found the same startling statistic: About twice as many women as men suffer from depression. That finding was considered one of the bedrock facts of modern mental health. Yet it has recently come under attack from critics who are concerned about underreporting of male depression. William Pollack, Director of the Center for Men at McLean Hospital, is leading the charge against the well-entrenched depression gender gap. He argues that men's rate of depression may be nearly equal to women's. Just look at suicide rates, he says: Male suicides outnumber females four to one. That ratio "is way too high to say that men's depression numbers are so low," he notes. Pollack and others contend that male depression goes unrecognized because, unlike the female version, it often doesn't fit the textbook signs—at least in the early stages. Clinical depression at later stages looks much the same in both sexes. But in the prelude to a breakdown, that deepening despair is often expressed in very different ways. Instead of being weepy, men are more apt to be irritable and angry—moods that aren't included in the classic diagnostic tests. "Their sadness and helplessness are hidden behind a mask of anger," says Pollack. "Men tend to act out" to avoid dealing with uncomfortable feelings, adds Fredric Rabinowitz, a psychologist who works primarily with men. If they feel bad, they're apt to get into fights on the job or at home, withdraw from family and friends, become obsessed with work or hobbies. Most significantly, men often turn to drinking or drugs. Men have two to four times the rate of substance abuse problems as women, and Pollack contends that if this was recognized as a sign of depression, the gender gap would substantially narrow.

单选题In the world of entertainment, TV talk shows have undoubtedly flooded every inch of space on daytime television. And anyone who watches them regularly knows that each one varies in style and format. But no two shows are more profoundly opposite in content, while at the same time standing out above the rest, than the Jerry Springer and the Oprah Winfrey shows. Jerry Springer could easily be considered the king of "trash talk (废话)". The topics on his show are as shocking as shocking can be. For example, the show takes the ever-common talk show themes of love, sex, cheating, guilt, hate, conflict and morality to a different level. Clearly, the Jerry Springer show is a display and exploitation of society"s moral catastrophes (灾难)， yet people are willing to eat up the intriguing predicaments (困境) of other people"s lives. Like Jerry Springer, Oprah Winfrey takes TV talk show to its extreme, but Oprah goes in the opposite direction. The show focuses on the improvement of society and an individual"s quality of life. Topics range from teaching your children responsibility, managing your work week, to getting to know your neighbors. Compared to Oprah, the Jerry Springer show looks like poisonous waste being dumped on society. Jerry ends every show with a "final word". He makes a small speech that sums up the entire moral of the show. Hopefully, this is the part where most people will learn something very valuable. Clean as it is, the Oprah show is not for everyone. The show"s main target audience are middle-class Americans. Most of these people have the time, money, and stability to deal with life"s tougher problems. Jerry Springer, on the other hand, has more of an association with the young adults of society. These are 18 to 21-year-olds whose main troubles in life involve love, relationship, sex, money and peers. They are the ones who see some value and lessons to be learned underneath the show"s exploitation. While the two shows are as different as night and day, both have ruled the talk show circuit for many years now. Each one caters to a different audience while both have a strong following from large groups of fans. Ironically, both could also be considered pioneers in the talk show world. (388 words)

单选题Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D. We have known for a long time that the organization of any particular society is influenced by the definition of the sexes and the distinction drawn between them. But we have realized only recently that the identity of each sex is not so easy to pin down, and that definitions evolve in accordance with different types of culture known to us, that is, scientific discoveries and ideological revolutions. Our nature is not considered as immutable, either socially or biologically. As we approach the beginning of the 21st century, the substantial progress made in biology and genetics is radically challenging the roles, responsibilities and specific characteristics attributed to each sex, and yet, scarcely twenty years ago, these were thought to be "beyond dispute" We can safely say, with a few minor exceptions, that the definition of the sexes and their respective functions remained unchanged in the West from the beginning of the 19th century to the 1960s. The role distinction, raised in some cases to the status of uncompromising dualism on a strongly hierarchical model, lasted throughout this period, appealing for its justification to nature, religion and customs alleged to have existed since the dawn of time. The woman bore children and took care of the home. The man set out to conquer the world and was responsible for the survival of his family, by satisfying their needs in peacetime and going to war when necessary. The entire world order rested on the divergence of the sexes. Any overlapping or confusion between the roles was seen as a threat to the timehonored order of things. It was felt to be against nature, a deviation from the norm. Sex roles were determined according to the "place" appropriate to each. Women's place was, first and foremost, in the home. The outside world, i. e. workshops, factories and business firms, belonged to men. This sex-based division of the world (private and public) gave rise to a strict dichotomy between the attitudes, which conferred on each its special identity. The woman, sequestered at home, "cared, nurtured and conserved" . To do this, she had no need to be daring, ambitious, tough or competitive. The man, on the other hand, competing with his fellow men, was caught up every day in the struggle for survival, and hence developed those characteristics which were thought natural in a man. Today, many women go out to work, and their reasons for doing so have changed considerably. Besides the traditional financial incentives, we find ambition and personal fulfillment motivating those in the most favorable circumstances, and the wish to have a social life and to get out of their domestic isolation influencing others. Above all, for all women, work is invariably connected with the desire for independence.
