单选题True, some of the attacks against whites by blacks are for money and valuables. But, others ale revenge assaults by blacks for a real or imagined racial insult. It is equally true that the vast majority of violent crimes against whites are committed by whites, while the vast majority of violent crimes against blacks are committed by other blacks. Yet even after discounting crimes that are hastily and erroneously (错误地，不正确地) tagged as racially motivated, many blacks do attack whites because they all white. A 1998 Justice Department study confirmed that nearly 20% of the more than 4,000 hate crimes well committed against whites, and their attackers were blacks. The Southern Poverty Law Center also notes that there is a huge escalation in black-on- white violence from nearly none at the beginning of the 1990s. A collection of white supermacists and rightist extremist groups have eagerly made black-on- white violence a wedge issue in their movement to paint blacks as the prime racial hate mongers in America. The New Century Foundation, an ultra-conservative think-tank, has launched a full- blown national campaign to alert whites to the danger of black hate crimes. These groups and individuals magnify hate crimes by blacks in order to back their social agenda. They oppose affirmative action programs and stronger hate crime laws. They downplay, or justify, the proliferation of white-supremacist-tinged paramilitary groups, police violence, and racial profiling. And they lobby hard for more prisons, police, and tougher laws. Black-on-white violence also reinforces white fears of blacks as the ultimate menace to society. When blacks say or do nothing about these attacks, it is taken by some as a tacit signal that blacks put less value on white lives than black lives. This is a terrible price for black silence on hate crimes committed by blacks.

单选题Which of the following is NOT mentioned in the text?

单选题{{B}}Text 3{{/B}} Some drug makers pay key leaders in a field of medicine, such as chairs of departments in medical schools, tens of thousands of dollars if they are saying the right things about their product. They manipulate medical education sessions, lectures, articles in medical journals, research studies, even personal conversations between physicians to get their product message across. Now a huge collection of drug company internal documents--revealed as part of a lawsuit—offers a wealth of detail. In 1996, Dr. David Franklin, an employee of the drug company Parke-Davis, filed the lawsuit under federal whistleblower statutes alleging that the company was illegally promoting a drug called Neurontin for so called "off-label' uses. Under federal law, once the FDA approves a drug, a doctor can prescribe it for anything. But the law specifically prohibits the drug company from promoting the drug for any unapproved uses. In 2004, the company, by then a division of Pfizer admitted guilt and agreed to pay $ 430 million in criminal and civil liability related to promoting the drug for off-label use. Spokespeople for Pfizer say that any wrong doing occurred before Pfizer acquired the company. But Pfizer fought hard to keep all the papers related to the suit under seal. A judge denied the request and they are now part of the Drug Industry Document Archive at the University of California, San Francisco. What is most interesting is not the illegal actions they reveal, but the details of activities that are perfectly legal. And according to people familiar with the industry, the methods detailed in these company memos are routine. One tactic identifies certain doctors as "thought leaders, "—those whose opinions influence the prescribing pattern of other doctors. Those whose views converge with the company goals are then showered with rewards, research and educational grants. In the Parke-Davis case 14 such big shots got between $10,250 and $158,250 between 1993 and 1997. "Medical education drives this market," wrote the author of one Parke-Davis business plan in the files. Many state licensing boards require physicians to attend sessions in what is called continuing medical education (CME) to keep current in their field. At one time, medical schools ran most CME courses. Now, an industry of medical education and communications committees (MECCs) run most of the courses. These companies with innocent sounding names like Medical Education Systems set up courses, sometimes in conjunction with medical meetings, at other times often in fancy restaurants and resorts. The drug companies foot the bill, with the program usually noting it was financed by an." unrestricted educational grant" from the company. Using MECCs, Parke-Davis set up conference calls so that doctors could talk to one another about the drugs. The moderators of the calls, often thought leaders or their younger assistants, received $250 to $500 a call. Drug company reps were on the line, instructed to stay in a "listen only" mode, but monitoring to be sure the pitch met their expectations. Clearly, 'many of the physicians in these schemes are not innocent bystanders. Whether it is ghost writing, making telephone calls to colleagues or leading a CME session, many of the doctors got paid well. Others received a free meal or transportation to a resort to listen to an "educational session." Physicians often claim they are not influenced by payments from the pharmaceutical industry. But with the methods so thoroughly detailed in these papers, drug companies clearly believe they are getting their money's worth.

单选题We ail know that it is possible for ordinary people to make their homes on the equator (赤道) ,although often they may feel uncomfortably hot there. Millions do it. But as for the North Pole (北极)—we know that it is not only a dangerously cold place, but that people like you and I would find it quite impossible to live there. At the present time only the scientists and explorers can do so, and they use special equipment. (76)Men have been travelling across and around the equator on wheels, on their feet or in ships for thousands of years; but only a few men, with great difficulty and in very recent time. have ever crossed the ice to the North Pole. So it may surprise you to learn that, when traveling by air, it is really safer to fly over the North Pole than over the equator. Of course, it is not true about landings in the polar region, but the weather, if we are flying at a height of 5,000 meters above the Pole is a delight. At 4,000 meters and move above the earth you can always be sure that you will not see a cloud in the sky as far as your eyes can reach. In the tropics (热带), on the other hand, you are not certain to keep clear of bad weather even at such heights as 18,000 or 20,000 meters. Aeroplanes can' t climb as high or as quickly in cold air as in warm. Nor can clouds. (77) practice, this is an advantage to the aeroplane, which is already at a good height when it reaches the polar region and so does not to climb, while at the same time cold air keeps the clouds down low.
