Mark your answers on ANSWER SHEET 1.{{B}}Text 1{{/B}} How did the company come to produce a record glorifying the murder of police, which is entitled Cop Killer by the rapper Ice-T on the album Boby Count? The album is released by Warner Bros. Records, part of the Time Warner media and entertainment conglomerate. In a Wall Street Journal oped piece laying out the company's position? Time Warner co- CEO Gerald Levin makes two defenses. First, Ice-T's Cop Killer is misunderstood. "It doesn't induce or glorify violence... It's his fictionalized attempt to get inside a character's head ... Cop Killer is no more a call for gunning down the police than Frankie and Johnny is a summons for jilted lovers to shoot one another." Instead of "finding ways to silence the messenger," we should be "heeding the anguished cry contained in his message." This defense is self-contradictory. Frankie and Johnny does not pretend to have a political "message" that must be "heeded." If Cop Killer has a message, it is that the murder of policemen is a justified response to police brutality. And not in self-defense, but in premeditated acts of revenge against random cops. Killing policemen is a good thing--that is the plain meaning of the song, and no "larger understanding" of black culture, the rage of the streets or anything else can explain it away. As in much of today's popular music, the line between performer and performance is purposely blurred. These are political sermonettes clearly intended to support the sentiments being expressed. Traey Marrow (Ice-T) himself has said, "I scared the police, and they need to be scared." That seems clear. The company's second defense of Cop Killer is the classic one of free expression: "We stand for creative freedom. We believe that the worth of what an artist or journalist has to say does not depend on preapproval from a government official or a corporate censor." Of course Ice-T has the right to say whatever he wants. But that doesn't require any company to provide him an outlet. And it doesn't relieve a company of responsibility for the messages it chooses to promote. Judgment is not "censorship." Many an "anguished cry" goes unrecorded. This one was recorded, and promoted, because a successful artist under contract wanted to record it. Nothing wrong with making money, but a company cannot take the money and run from the responsibility. The founder of Time, Henry Luce, would have scorned the notion that his company provided a value-free forum for the exchange of ideas. In Luce's system, editors were supposed to make value judgments and promote the truth as they saw it.

单选题B. F. Skinner______.

单选题When I was in high school, I had almost no individual identity left. I was a Hillcrest Husky and all other high schools were enemies. I was a wrestler and all the other sports were gor wimps. I was on the debate team and everyone else was dumb. At my high school, everyone had a group; no one was an individual. Wait. I take that back. There were a few individuals, but they were completely outcast from our social order. Never in my life can I remember stronger feelings of hate tian in high school. But we never called it hate. We called it loyalty. As adults, most of us are better at being an individual than we were in high school, but the influences of group identity continue to promote competition and prejudice in our world. If you are like me, you want to avoid teaching rivalry, conflict and prejudice to your children. One possible strategy for stopping the negative influences of group identity would be: recognize and replay. Look for the prejudice in your life and replace it with charity. Treat every person as an individual and ignore the social classifications created by a group-dependent world. A good friend and I once discussed our differing religions beliefs. He identified with a certain group and I with another. Because of our dependence on group identity, our conversations revolved around the beliefs of the groups. Our individual beliefs, which were quite similar, took a back seat while we discussed topics we knew little about. We defended our groups even when we did not understand or know the official group position on many issues. The resulting rivalry has damaged our friendship ever since. My behavior in this situation is exactly what scripture and wisdom teach us to avoid. How stupid I was to judge my friend by a group standard! How stupid I was to defend my own group even in areas I knew nothing about! I hope I can teach my children to behave differently. Here, I have used religious beliefs to point only one area in which the influence of group identity can create problems. There are many others to consider also. Some of these are marriage, race, culture, language, geographic origin, education, and behavior. We should treat all people as individuals regardless of these conditions. Finally, loyalty and group identity are not always bad. At times, they can help a lonely person to feel loved or a broken soul to feel success. Group identity can also help us to live a higher standard. But positive peer pressure should never replace individual, one-to-one acts of service and love.

单选题Cigarette smoking is a health hazard of sufficient importance in the United States. It was 50 years ago this month that America"s Surgeon General sounded that warning, marking the beginning of the end of cigarette manufacturing—and of smoking itself—as a respectable activity. Some 20 million Americans have died from the habit since then. But advertising restrictions and smoking bans have had their effect: the proportion of American adults who smoke has dropped from 43% to 18%; smoking rates among teenagers are at a record low. In many other countries the trends are similar. The current Surgeon General, Boris Lushniak, marked the half-century with a report on January 17th, declaring smoking even deadlier than previously thought. He added diabetes, colorectal cancer and other ailments to the list of ills it causes, and promised end-game strategies to extinguish cigarettes altogether. New technologies such as e-cigarettes promise to deliver nicotine less riskily. E-cigarettes give users a hit of vapour infused with nicotine. In America, sales of the manufacturer, who is the fastest e-cigarettes-adopter, have jumped from nearly nothing five years ago to at least 1 billion in 2013. At first, it looked as if e-cigarettes might lure smokers from the big tobacco brands to startups such as NJOY. But tobacco companies have bigger war chests , more knowledge of smokers" habits and better ties to distributors than the newcomers. Some experts reckon Americans will puff more e-cigarettes than normal ones within a decade, but tobacco folk are skeptical. E-cigarettes account for just 1% of America"s cigarette market. In Europe 7% of smokers had tried e-cigarettes by 2012 but only 1% kept them up. And no one knows what sort of restrictions regulators will eventually place on reduced risk products, including e-cigarettes. If these companies can manage the transition to less harmful smokes, and convince regulators to be sensible, the tobacco giants could keep up the sort of performance that has made their shares such a fine investment over the years. But some analysts are not so sure. Many tobacco firms are struggling to deliver the consistency of the earnings-per-share model we"ve seen in the past. If that persists, investors may fall out of love with the industry. A half-century after the Surgeon General"s alarm, they, and hopeless smokers, are its last remaining friends.

单选题In the first sentence of Paragraph 2, "interpreting" probably refers to ______.

单选题When an invention is made, the inventor has three possible (1) of action open to him: he can give the invention to the world by publishing it, keep the idea (2) , or patent it. A (3) patent is the result of a bargain (4) between an inventor and the state, hut the inventor gets a limited period of monopoly and publishes full details of his invention to the public after that period (5) . Only in the most exceptional circumstances (6) the lifespan of a patent (7) to alter this normal process of events. The longest extension ever (8) was to Georges Valensi; his 1939 patent for color TV receiver circuit was extended until 1971 because for most of the patent's normal life there was no color TV to (9) and thus no hope for reward for the invention. Because a patent remains permanently (10) after it has terminated, the shelves of the library attached to the (11) office contain details of literally millions of ideas that are free for anyone to use and, if (12) than half a century, sometimes even repatent. Indeed, patent experts often advise anyone (13) to avoid the high cost of conducting a search through (14) patents that the one sure way of violation of any other inventor's right is to plagiarize a dead patent. Likewise, because publication of an idea in any other form (15) invalidates further patents on that idea, it is traditionally (16) to take ideas from other areas of print. Much modern technological advance is (17) on these presumptions of legal security. Anyone closely (8) in patents and inventions soon learns that most "new" ideas are, in fact, as old as the hills. It is theft reduction to commercial practice, either through necessity or dedication, or through the availability of new technology, (19) makes news and money. The basic patent for the theory for magnetic recording dates back to 1886. Many of the original ideas behind television originate (20) the late 19th and early 20th century. Even the Volkswagen rear engine ear was anticipated by a 1904 patent for a cart with the horse at the rear.

单选题Gene therapy and gene based drugs are two ways we could benefit from our growing mastery of genetic science. But there will be others as well. Here is one of the remarkable therapies on the cutting edge of genetic research that could make their way into mainstream medicine in the coming years. While it's true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so called stem cells haven't begun to specialize. Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy cells—brain cells in Alzheimer's, cardiac cells in heart disease, pancreatic cells in diabetes, to name a few; if doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue. It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can't be controlled, and may have unforeseen limitations; but if efforts to understand and master stem cell development prove successful, doctors will have a therapeutic tool of incredible power. The same applies to cloning, which is really just the other side of the coin. True cloning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, resetting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full-fledged animal, genetically identical to its parent. For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year. Human cloning, on the other hand, may be technically feasible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells: the potential to make healthy body tissues of all sorts, and thus to cure disease. That could prove to be a true "miracle cure".

单选题 For 22 years America has banned HIV-positive people from entering the country without a hard-to-get waiver for fear of the virus spreading. It has not hosted a big international AIDS conference in more than a decade either, because many HIV-positive activists would not be allowed to attend. Only a dozen other countries, including China and Russia, have similar restrictions, and there is no evidence that these bans halt the spread of AIDS. Instead, many say, it makes things worse by stigmatizing carriers of the virus. On October 30th Barack Obama announced that he will do away with this cruel rule. From 2010, HIV-positive people will be able to travel to America and will also be able to apply for citizenship there. Reversing the ban will bring families together who were separated because of HIV. "Thank you. Thank you. Thank you," wrote Andrew Sullivan, a British journalist who is HIV-positive after Mr. Obama's announcement. He has been nervous when visiting his family in Britain for fear that he would not be allowed to re-enter America, where he and his husband live. Reversing the travel ban may help Mr. Obama combat HIV/AIDS domestically by emphasizing that it is a national disease, not one brought in by foreigners. Around 1.1m Americans are HIV-positive, and more needs to be done to address the spread of the virus. There were more than 56,000 new infections in America in 2006, according to the Centers for Disease Control. Metropolitan areas have particularly high AIDS rates. The incidence of HIV/AIDS in Washington, DC, is so high (around 3%) that it has inspired an AIDS organization to put up posters calling AIDS "DC's Katrina". This is Mr. Obama's first policy change when it comes to fighting AIDS at home, and it is something that human-rights advocates and gay-rights groups have been demanding for years. Mr. Obama has also appointed an AIDS "tsar" and says he is working to develop a national AIDS strategy. But as he gets his ducks in order, the situation is getting worse. State budget cuts have left some people without access to treatment, and in some states waiting-lists for cheap antiretroviral drugs are long. Mr. Obama also reauthorized the Ryan White CARE Act, which provides funding for AIDS treatment. Many worry, though, that when the money comes through it will not be enough to compensate for the cuts to AIDS programs that states have already made. By reversing the ban, Mr. Obama has made good on one of his promises to his gay supporters, who have felt overlooked so far during his presidency. But the good news was followed, on November 3rd, by the overturning in a referendum of a law permitting gay marriage in Maine.
