Of all the components of a good night’s sleep, dreams seem to be least within our control. In dreams, a window opens into a world where logic is suspended and dead people speak. A century ago, Freud formulated his revolutionary theory that dreams were the disguised shadows of our unconscious desires and fears; by the late 1970s, neurologists had switched to thinking of them as just “mental noise” -- the random byproducts of the neural-repair work that goes on during sleep. Now researchers suspect that dreams are part of the mind’s emotional thermostat, regulating moods while the brain is “off-line.” And one leading authority says that these intensely powerful mental events can be not only harnessed but actually brought under conscious control, to help us sleep and feel better, “It’s your dream,” says Rosalind Cartwright, chair of psychology at Chicago’s Medical Center. “If you don’t like it, change it.”
Evidence from brain imaging supports this view. The brain is as active during REM (rapid eye movement) sleep -- when most vivid dreams occur -- as it is when fully awake, says Dr, Eric Nofzinger at the University of Pittsburgh. But not all parts of the brain are equally involved; the limbic system (the “emotional brain”) is especially active, while the prefrontal cortex (the center of intellect and reasoning) is relatively quiet. “We wake up from dreams happy or depressed, and those feelings can stay with us all day.” says Stanford sleep researcher Dr. William Dement.
The link between dreams and emotions show up among the patients in Cartwright’s clinic. Most people seem to have more bad dreams early in the night, progressing toward happier ones before awakening, suggesting that they are working through negative feelings generated during the day. Because our conscious mind is occupied with daily life we don’t always think about the emotional significance of the day’s events -- until, it appears, we begin to dream.
And this process need not be left to the unconscious. Cartwright believes one can exercise conscious control over recurring bad dreams. As soon as you awaken, identify what is upsetting about the dream. Visualize how you would like it to end instead; the next time is occurs, try to wake up just enough to control its course. With much practice people can learn to, literally, do it in their sleep.
At the end of the day, there’s probably little reason to pay attention to our dreams at all unless they keep us from sleeping or “we waken up in a panic,” Cartwright says. Terrorism, economic uncertainties and general feelings of insecurity have increased people’s anxiety. Those suffering from persistent nightmares should seek help from a therapist. For the rest of us, the brain has its ways of working through bad feelings. Sleep -- or rather dream -- on it and you’ll feel better in the morning.

[A] can be modified in their courses
[B] are susceptible to emotional changes
[C] reflect our innermost desires and fears

Even though they were forced to serve in separated units, black soldiers distinguished themselves in combat. This was despite the fact the whites had long believed that blacks could neither command nor use firearms. In 1863, William Carney of the Massachusetts Colored Infantry received the Congressional Medal of Honor for his role in battles with the Plains Indians. Isaiah Dorman, Coster's black scout, served and died at the Little Big Horn in 1876. Henry Flipper was the first black graduate of West Point in 1877.
In World War I, 40,000 black American combat soldiers served with the French command. Neither U.S. nor British commanders would use these men. But Henry Johnson and Needham Roberts, soldiers in the 369th Infantry's black “Hellfighters” were still the first Americans to win the Croix de Guerr, France's top military award.
During World War II over 600,000 black men and women served in the armed forces, including some 400,000 who served overseas. Dorie Miller, a black mess attendant in navy, was one of our first heroes in this war. At Pearl Harbor during the Japanese sneak attack, he manned a machine gun and shot down four planes. The black fighter pilots of Benjamin Davis, Jr. distinguished themselves throughout the war. They served most courageously during the Italian campaign. During the war in Vietnam, mainly because of civil rights pressures in America but also owing to the fine record of black military units, all American forces were fully integrated. Once again blacks played vital roles. And 13. 2 percent of all war deaths were of blacks, even though blacks constitute only 11 percent of all Americans. Black American soldiers continue to serve their land well.
The main idea this passage is that______.
A．black Americans made contributions in the Revolutionary War
B．black Americans have admirably served their country in at least five wars
C．black Americans suffered a larger portion of war deaths in Vietnam than did any other minorities
D．black Americans served under the French command in World War I
听力原文： During the early American colonial years, corn was more plentiful than wheat, so corn bread was more common than wheat bread. Friendly Indians showed colonists how to grow corn and how to prepare it for food and pioneer women then improved the Indian cooking techniques. When people traveled, they went on foot or horseback, sleeping and eating in the forests. They carried corn bread for sustenance. The corn bread came to be called journeyeake. Later when roads and taverns were built and stagecoaches carried passengers, journeycake became johnnycake, a name many easterners still use for corn bread. The kinds of bread made with cornmeal were and still are almost without limit. Every region has its specialties.
From the start, southerners showed a preference for white eorm:neal, northerners for yellow. And pioneers on the frontier, when they ran out of yeast, made salt-rising bread. They stirred together water, a little water ground cornmeal, potatoes, and salt. They set the mixture, uncovered, in a warm place until it absorbed bacteria from the air and began to ferment. Then they removed the potatoes and used the liquid as leavening for their bread, made with white flour.

A．The colonists preferred corn bread.
B．Corn was more abundant.
C．The colonists did not know how to make wheat bread.
D．Corn bread did not spoil as rapidly as wheat bread did.
Survey results indicate that smoking and alcohol and marijuana(大麻) use increased among residents of Manhattan during the 5～8 weeks after the terrorist attacks on the World Trade Center which took place on September 11, 2001. Almost one third of the nearly 1,000 persons interviewed reported an increased use of alcohol, marijuana, or cigarettes following the September 11th attacks. The largest increase was in alcohol use. 1About one fourth of the respondents said they were drinking more alcohol in the weeks after September 11; about 10% reported an increase in smoking, and 3.2% said they had increased their use of marijuana.
The investigators found survey participants by randomly dialing New York City phone numbers and screened (筛选) potential respondents for Manhattan residents living in areas close to the World Trade Center. Interviews were conducted with 988 individuals between October 16 and November 15, 2001. Participants were asked about their cigarette smoking, alcohol drinking, and marijuana use habits before and after September 11. During the week prior to September 11, 2001, 22.6% of the participants reported smoking cigarettes, 59.1% drinking alcohol, and 4.4% using marijuana. After September 11th, 23.4% reported smoking cigarettes, 64.4% drinking alcohol, and 5.7% smoking marijuana. Among those who smoked, almost 10% reported smoking at least an extra pack of cigarettes a week and among those who drank alcohol, more than 20% reported drinking at least one extra drink a day.
The researchers found that people who reported an increase in substance abuse were more likely to suffer from post traumatic(外伤的)stress disorder (PTSD) and from depression. People who reported an increase in cigarette smoking or marijuana use were also more likely to have both P1SD and depression, while those who reported an increase in alcohol use were more likely to have depression only. Persons who were living closer to the World Trade Center were more likely to increase their cigarette smoking, but other factors such as being displaced from home, losing possessions during the attacks, or being involved in the rescue efforts were not consistently associated with increased substance use. Symptoms of panic attack were associated with an increase in the use of all substances.
Increase in substance abuse did not differ significantly between men and women or among racial or ethnic groups. Demographic(人口统计学的) factors such ms age, marital status, and income seemed to play a more critical role in determining if the events of September 11th led to an increase in substance use.
The survey results suggest that the largest increase in substance use was ______.
A．alcohol
B．marijuana
C．cigarettes
D．cocaine

Since the US Agency for International Development (USAID) began its first HIV/AIDS prevention efforts eight years ago, the epidemic has changed dramatically. HIV has spread to every region of the world. Millions of people infected with HIV during the first decade of the epidemic are developing opportunistic infections and other AIDS-related illnesses, and many are dying. Women and children are among those most vulnerable to HIV infection. As HIV prevalence and AIDS mortality soar, millions of children will lose their parents.
HIV/AIDS is having a devastating impact on the health and well-being of families, communities and nations worldwide. The epidemic's effects on the structure of societies and the productivity of their members undermine efforts to promote sustainable development around the globe.
USAID's approach to slowing the spread of HIV/AIDS relies on strategies tested and refined over the past eight years. At the same time, the Agency is moving forward to address new challenges posed by the evolving epidemic.
One of the important lessons learned during the past decade is that an effective response to HIV/ AIDS requires the full participation of people and communities affected by the virus. Although people living with HIV/AIDS are among the most successful advocates and communicators for prevention, too often their voices are not heard or heeded. Greater involvement of people living with HIV/AIDS is essential to creat the supportive political, legal and social environments needed to control the epidemic.
In December 1994 at the Paris AIDS Summit, representatives of 42 governments adopted resolution pledging greater support for networks of people living with HIV/AIDS. Before and during the summit, members of these networks worked with government and multilateral organizations, including USAID, to develop a plan for translating the words of the resolution into concrete action. The Agency is committed to ensuring that people living with HIV/AIDS are accepted in full partnership with governments, international organizations and the private sector in developing, implementing and evaluating HIV/AIDS policies and programs.
People living with HIV/AIDS and community-based organizations have been at the forefront of efforts to draw attention to the connection between compassionate AIDS care and effective HIV prevention. In the absence of a vaccine or cure, USAID continues to emphasize HIV/AIDS prevention. But as the number of people suffering from AIDS-related illness begins to increase dramatically, the Agency is also exploring ways to reduce the social impact of AIDS and enhance prevention efforts by integrating prevention and care.
The Agency will also continue to pioneer regional approaches to an epidemic that does not recognize national boundaries. Crossborder interventions throughout the world will target mobile populations, including migrant workers, tourists, traders, transport workers and people displaced by war, and social disruption.
Results from USAID-supported research on preventing HIV/AIDS in women, from microbiocide development to behavioral research on communication between men and women, will play a key role in slowing the rapid spread of the epidemic in the future. The Agency will continue to support research designed to strengthen programs for women and will move quickly to incorporate promising prevention methods into field activities. USAID will also work to reduce women's vulnerability to HIV prevention by promoting multisectoral efforts to improve their economic and social status.
Recognizing the growing threat HIV/AIDS poses to child survival, the Agency will support efforts to identify and test methods of preventing transmission from mother to child, such as Vitamin A supplements and other promising interventions. In addition, USAID will expand efforts to reduce HIV/ AIDS am
