单选题Passage Three The terrorist attacks in London Thursday served as a jarring reminder that in today's world, you never know what you might see when you pickup the newspaper or turn on the TV. Disturbing images of terror can trigger a visceral response no matter how close or far away from home the event happened. Throughout history, every military conflict has involved psychological warfare in one way or another as the enemy sought to break the morale of their opponent. But thanks to advances in technology, the popularity of the Internet, and proliferation of news coverage, the rules of engagement in this type of mental battle have changed. Whether it's a massive attack or a single horrific act, the effects of psychological warfare aren't limited to the physical damage inflicted. Instead, the goal of these attacks is to instill a sense of fear that is much greater than the actual threat itself. Therefore, the impact of psychological terror depends largely on how the acts are publicized and interpreted. But that also means there are ways to defend yourself and your loved ones by putting these fears into perspective and protecting your children from horrific images. What is psychological terror? "The use of terrorism as a tactic is predicated upon inducing a climate of fear that is incommensurate with the actual threat," says Middle Eastern historian Richard Bulliet of Columbia University. "Every time you have an act of violence. Publicizing that violence becomes an important part of the act itself." "There are various ways to have your impact. You can have your impact by the magnitude of what you do, by the symbolic character of target, or the horrific quality of what you do to a single person," Bulliet tells WebMD. "The point is that it isn't what you do, but it's how it's covered that determines the effect." For example, Bulliet says the Iranian hostage crisis, which began in 1979 and lasted for 444 days, was actually one of the most harmless things that happened in the Middle East in the last 25 years. All of the U.S. hostages were eventually released unharmed, but the event a psychological scar for many Americans who watched helplessly as each evening's newscast counted the days the hostages were being held captive. Bulliet says terrorists frequently exploit images of a group of masked individuals exerting total power over their captives to send the message that the act is a collective demonstration of the group's power rather than an individual criminal act. "You don't have the notion that a certain person has taken a hostage. 'It's an image of group power, and the force becomes generalized rather than personalized," says Bulliet. "The randomness and the ubiquity of the threat give the impression of vastly greater capacities." Psychiatrist Ansar Haroun, who served in the U.S. Army Reserves in the first Gulf War and more recently in Afghanistan, says that terrorist groups often resort to psychological warfare because it's the only tactic they have available to them. "They don't have M-16s, and we have M-16s, they don't have the mighty military power that we have, and they only have access to things like kidnapping," says Haroun, who is also a clinical professor of psychiatry at the University of California, San Diego. "In psychological warfare, even one beheading can have the psychological impact that might be associated with killing 1,0000 of the enemy," Haroun tells WebMD. "You haven't really harmed the enemy very much by killing one person on the other side, but in terms of inspiring fear, anxiety, terror, and making us all feel bad, you've achieved a lot of demoralization.

单选题{{B}}Passage 4{{/B}} The mental health movement in the United States began with a period of considerable enlightenment. Dorothea Dix was shocked to find the mentally ill in jails and almshouses and crusaded for the establishment of asylums in which people could receive human care in hospital-like environments and treatment which might help restore them to sanity. By the mid 1800s, 20 states had established asylums, but during the late 1800s and early 1900s, in the face of economic depression, legislatures were unable to appropriate sufficient funds for decent care. Asylums became overcrowded and prison-like. Additionally, patients were more resistant to treatment than the pioneers in the mental health field had anticipated, and security and restraint were needed to protect patients and others. Mental institutions became frightening and depressing places in which the rights of patients were all but forgotten. These conditions continued until after World War II. At that time, new treatments were discovered for some major mental illnesses theretofore considered untreatable (penicillin for syphilis of the brain and insulin treatment for schizophrenia and depressions), and a succession of books, motion pictures, and newspaper exposes called attention to the plight of the mentally ill. Improvements were made and Dr. David Vail's Humane Practices Program is a beacon for today. But changes were slow in coming until the early 1960s. At that time, the Civil Rights movement led lawyers to investigate America's prisons, which were disproportionately populated by blacks, and they in turn followed prisoners into the only institutions that were worse than the prisons-- the hospitals for the criminally insane. The prisons were filled with angry young men who, encouraged by legal support, were quick to demand their rights. The hospitals for the criminally insane, by contrast, were populated with people who were considered "crazy" and who were often kept obediently in their place through the use of severe bodily restraints and large doses of major tranquilizers. The young cadre of public interest lawyers liked their role in the mental hospitals. The lawyers found a population that was both passive and easy to champion. These were, after all, people who, unlike criminals, had done nothing wrong. And in many states, they were being kept in horrendous institutions, an injustice, which once exposed, was bound to shock the public and, particularly, the judicial conscience. Patients' rights groups successfully encouraged reform by lobbying in state legislatures. Judicial interventions have had some definite positive effects, but there is growing awareness that courts cannot provide the standards and the review mechanisms that assure good patient care. The details of providing day-to-day care simply cannot be mandated by a court, so it is time to take from the courts the responsibility for delivery of mental health care and assurance of patient rights and return it to the state mental healty administrators to whom the mandate was originally given. Though it is a difficult task, administrators must undertake to write rules and standards and to provide the training and surveillance to assure that treatment is given and patient rights are respected.

单选题Much of many managers' time is taken up with meetings. There are meetings with colleagues to agree a course of action. There are meetings with superiors to report and to discuss future policies. There are meetings with subordinates. Many would say that there are far too many meetings; some would be even less polite. There can, however, be no doubt that meetings are part of every manager's life. He should therefore know how to cope with them. He should know the techniques of communication in meetings. He should know how to use these techniques to his own advantage. It is sometimes suggested that when a manager can't think what to do, he holds a meeting. But meetings in themselves are not an end product, no matter what some may think. They are merely one of many means of management communication. It may well be that a problem can be solved by a one-to-one discussion, face-to-face, or even by telephone. If the need can be met without a meeting, so be it. Let us therefore define a meeting, in the management sense, as the gathering together of a group of people for a controlled discussion, with a specific purpose. Each of those attending the meeting has a need to be there and both discussion and its result would not be so well achieved in any other way. It is often advisable to calculate the cost of a meeting. A simple meeting of a few people on middle-executive salaries can soon run into three-figure costs for wages alone. Do not, therefore, have unnecessary people sitting in at meetings and do ensure that all meetings are both efficient and effective.
