单选题A class action lawsuit has been filed against a prominent Toronto doctor, by patients who allege he injected a banned substance into their faces for cosmetic purposes. The doctor had already been investigated more than three years ago for using the liquid silicone, a product not authorized for use in Canada. Some patients say they are now suffering health problems and think the liquid silicone may be to blame. One of those patients is Anna Barbiero. She says her Toronto dermatologist told her he was using liquid silicone to smooth out wrinkles. What she says he didn't tell her is that it isn't approved for use in Canada. "I didn't know what liquid silicone was and he just called it ' liquid gold' ," Barbiero remembers. After her last treatment, Anna discovered Dr. Sheldon Pollack had been ordered to stop using the silicone two years earlier by Health Canada. Experts say silicone can migrate through the body, and cause inflammation and deformities. "My upper lip is always numb and it burns," Barbiero says. Barbiero is spearheading a lawsuit against the doctor, who her lawyer thinks might involve up to 100 patients injected with the same material. "The fact, a physician of his stature would use an unauthorized product on a patient because he thought it was okay, is really very disturbing, "says lawyer Douglas Elliott. Ontario's College of Physicians and Surgeons (OCPS) is also investigating Dr. Pollack to see if, in fact, he continued to use the silicone after agreeing to stop and whether he wrote in patient records that he used another legal product when he had used silicone. However, in a letter to the College, Dr. Pollack wrote that he had always told patients that the silicone was not approved for sale in Canada, and had warned them of the risks. And in Barbiero's case, " ... at the time of her first visit, prior to her ever receiving IGLS treatment, I specifically informed her that the material was not approved for sale in Canada by the Health Protection Branch and that I did receive the material from outside the country... I would like to emphasize that, as is evident on Ms. Barbiero's chart, I drew a specific diagram on the chart which 1 carefully discussed with and explained to Ms. Barbiero as I do with every other patient to explain the nature and likelihood of possible complications and the reasons and consequences of those possible complications. " Dr. Pollack declined to speak to CTV News, or to have his lawyer discuss the case. None of the allegations have been proven in court. But the case raises questions about the ability of governing bodies to monitor doctors. "There's a larger message and that is. buyer beware," says Nancy Neilsen of Cosmetic Surgery Canada. "It's incumbent on consumers to do their research. /

单选题When they advise your kids to "get an education" if you want to raise your income, they tell you only half the truth. What they really mean is to get just enough education to provide manpower for your society, but not too much that prove an embarrassment to your society. Get high school diploma, at least. Without that, you are occupationally dead, unless your name happens to be George Bernard Shaw or Thomas Alva Edison and you can successfully drop out in grade school. Get a college degree, if possible. With a B.A., you are on the launching pad(发射台). But now you have to start to put on the brakes. If you go for a master's degree, make sure it is a M. B. A., and only from a first-rate university. Beyond this, the famous law of diminishing returns begins to take effect. Do you know, for instance, that long-haul truck drivers earn more a year than full professors? Yes, the average 1977 salary for those truckers was ＄24000, while the full professors managed to average just ＄23930. A Ph. D. is the highest degree you can get, but except in a few specialized fields such as physics or chemistry, where the degree can quickly be turned to industrial or commercial purposes, you are facing a dim future. There are more Ph. D.s unemployed or underemployed in this country than in any other part of the world by far. If you become a doctor of philosophy in English or history or anthropology or political science or language or—worst of all—in philosophy, you run the risk of becoming overeducated for our national demands. Not for our needs, mind you, but for our demands. Thousands of Ph. D. s are selling shoes, driving cabs, waiting on tables and filling out fruitless applications month after month. And then maybe taking a job in some high school or backwater college that pays much less than the janitor(看门人)earns. You can equate the level of income with the level of eduction only so far. Far enough, that is, to make you useful to the gross national product, but not so far that nobody can turn much of a profit on you.

单选题The word "substantially" (Para. 5, Line2) most likely means

单选题The road to controlling population growth in the 20th century was paved with good intentions and unpleasant policies that did not work, a new book argues an historian who grew up as the youngest of eight children might well be expected to approach the question of whether the world is overpopulated from an unusual angle. Matthew Connelly, a professor at Columbia University, dedicates his study of those who thought the planet had too many people and tried to do something about it to his parents, "for having so many children". Yet, he assures the reader, it Was not his personal experience of large families that drew him to the subject. Mr. Connelly's mentor, Paul Kennedy of Yale University, believed it was necessary to look beyond great-power rivalries to understand the post-cold-war era. In 1994 the pair wrote an article for Atlantic Mouthly arguing that population growth in poor countries, increasing awareness of global economic inequality and the prospect of mass migration could lead to clashes between the West and "the rest". When, years later, Mr. Connelly began his own book on population growth, he still thought of the topic as a way to offer a broader understanding of world security. He ended up writing a very different-and angry-book, one about people who looked at the human race reproducing itself and saw what a gardener sees when looking at a prize plant: something to be encouraged to bloom in some places and pruned in others. As the world population soared, the population controllers came to believe they were fighting a war, and there would be collateral damage. Millions of devices were exported to poor countries although they were known to cause infections and sterility. "Perhaps the individual patient is expendable in the general scheme of things," said a participant at a conference on the devices organized in 1962 by the Population Council, a research institute founded by John [D] Rockefeller, "particularly if the infection she acquires is sterilizing but not lethal. " Furthermore, statistical estimates suggest that as much as 90% of the reason that women have families of a particular size is simply because that is the number of children they want. Where women gained education and rights, birth rates fell. As with reproduction itself, for people to become less fruitful, desire must precede performance.

单选题{{B}}Text 4{{/B}} To Journalists, three of anything makes a trend. So after three school shootings in six days, speculation about an epidemic of violence in American classrooms was inevitable, and wrong. Violence in schools has fallen by half since the mid-1990s; children are more than 100 times more likely to be murdered outside the school walls than within them. On September 27th a 53-year-old petty criminal, Duane Morrison, walked into a school in Bailey, Colorado, with two guns. He took six girls hostage, molested some of them, and killed one before committing suicide as police stormed the room. And on September 29th a boy brought two guns into his school in Cazenovia, Wisconsin. Prosecutors say that 15-year-old Eric Hainstock may have planned to kill several people. But staff acted quickly when they saw him with a shotgun, calling the police and putting the school into "lock-down". The head teacher, who confronted him in a corridor, was the only one killed. October 2nd a 32-year-old milk-truck driver, Charles Roberts, entered a one-room Amish school in Nickel Mines, Pennsylvania. He lined the girls up, tied their feet and, after an hour, shot them, killing at least five. He killed himself as police broke into the classroom. What to make of such horrors? Some experts see the Colorado and Pennsylvania cases as an extreme manifestation of a culture of violence against women. Both killers appeared to have a sexual motive, and both let all the boys in the classroom go free. But it is hard to infer from such unusual examples, and one must note that violence against women is less than half what it was in 1995. Other experts see all three cases as symptomatic of a change in the way men commit suicide. Helen Smith, a forensic psychologist, told a radio audience "men are deciding to take their lives, "and they're not going alone anymore. They're taking people down with them." True, but not very often. Gun-control enthusiasts think school massacres show the need for tighter restrictions. It is too easy, they say, for criminals such as Mr. Morrison and juveniles such as Mr. Hainstock to obtain guns. Gun enthusiasts draw the opposite conclusion: that if more teachers carried concealed handguns, they could shoot potential child-killers before they kill. George Bush has now called for a conference on school violence. Will it unearth anything new, or valuable? After the Columbine massacre in 1999, the FBI produced a report on school shooters. It concluded that it was impossible to draw up a useful profile of a potential shooter because "a great many adolescents who will never commit violent acts will show some of the behaviours on any checklist of warning signs."

单选题{{B}}Text 3{{/B}} "I was a lover, before this war." Those are the fast words sung on TV on the Radio's "Return to Cookie Mountain," one of the most widely praised albums of 2006. Whatever the line means within the band's cryptic lyrics, it could also apply to the past year's popular music. Thoughts of romance, vice and comfort still dominated the charts and the airwaves. But amid the entertainment, songwriters— including some aiming for the Top 10—were also grappling with a war that wouldn't go away. Pop's political consciousness rises in every election year, and much as it became clear in November that voters are tired of war, music in 2006 also reflected battle fatigue. Beyond typical wartime attitudes of belligerence, protest and yearning for peace, in 2006 pop moved toward something different: a mood somewhere between resignation and a siege mentality. Songs that touched on the war in 2006 were suffused with the mournful and resentful knowledge that—s Nell Young titled the album he made and rush-released in the spring—we are "Living With War," and will be for some time. Awareness of the war throbs like a chronic headache behind more pleasant distractions. The cultural response to war in Iraq and the war on terrorism—one protracted, the other possibly endless—doesn't have an exact historical parallel. Unlike World War Ⅱ, the current situation has brought little national unity; unlike the Vietnam era, ours has no appreciable domestic support for America's opponents. Iraq may be mining into a quagmire and civil war like Vietnam, but the current war has not inspired talk of generation wide rebellion (,perhaps because there's no draft m pit young against old) or any colorful, psychedelically defiant counterculture. The war songs of the 21st century have been sober and earnest, pragmatic rather than fanciful. Immediate responses to 9/11 and to the invasion of Iraq arrived along familiar lines. There was anger and saber-rattling at first, particularly in country music: the Dixie Chicks' career was upended in 2003 when Natalie Maines disparaged the president on the eve of the Iraq invasion. There were folky protest songs about weapons and oil profiteering, like "The Price of Oil" by Billy Bragg; in a 21st-century touch, there were denunciations of news media complicity from songwriters as varied as Merle Haggard, Nellie McKay and the punk-rock band Anti-Flag. Rappers, who were already slinging war metaphors for everything from rhyme battles to tales of drag-dealing crime soldiers, soon exploited the multitude of rhymes for Iraq. while some. like Eminem and OutKast, also bluntly attacked the president and the war. In 2006 songwriters who Usually stick to love songs found themselves paying attention to the war as well. "A new year, a new enemy/another soldier gone to war," John Legend sings in "Coming Home," the song that ends his 2006 album, "Once Again." it's a soldier's letter home, wondering if his gtrlfriend still cares. "It seems the wars will never end. but we'll make it home again," Mr. Legend croons, more wishful than confident.

单选题As thick-skinned elected officials go, FIFA President Joseph S. Blatter is right up there with Bill Clinton. The chief of the Zurich based group that oversees World Cup soccer hasn't been accused of groping any interns, but that's about all he hasn't been accused of. Vote buying, mismanagement, cronyism—and that's just for starters. Yet the 66-year-old Swiss shows no sign of abandoning his campaign for a second four-year term. Blatter, a geek of dispensing FIFA'S hundreds of million in annual revenue to inspire loyalty, even stands a good chance of reelection. At least he did. Since mid-March, he has seen a credible challenger emerge in Issa Hayatou, president of the African Football Confederation. Hayatou, a 55-year-old from Cameroon, leads a group of FIFA reformers that also includes FIFA Vice-President Lennart Johansson, a Swede who lost the presidential election to Blatter in 1998. These contenders' mission: to end what they call the culture of secrecy and lack of accountability that threatens FIFA with financial disaster. Representatives of the world's 204 national soccer associations meet in Seoul on May 29, and the rebels are given a chance of unseating Blatter. But even they concede that the FIFA honcho won't be easy to dislodge. Blatter's staying power seems incredible, given the array of misdeeds attributed to him and his circle. However, there are signs that FIFA'S troubles are bigger than Blatter is saying. The insurgents have already won one victory: They persuaded the rest of the executive board to order an audit of FIFA finances. But Blatter who claims, through a spokesman, that the accusations are a smear campaign-should not be underestimated. At least publicly, sponsors and member associations remain remarkably silent with the controversy. For example, there is no outward sign of outrage from German sports equipment maker Adidas-Salomon, which is spending much of its ＄625 million marketing budget on the World Cup. "We don't expect current developments within FIFA to have a negative impact on our expectations" for the World Cup, says Michael Riehl, Adidas head of global sports marketing. The conventional wisdom is that fans don't care about FIFA politics. Says Bernd Schiphorst, president of Hertha BSC Berlin, a top ranked German team: "I've no fear that all these discussions are going to touch the event." Still, the Olympic bribery scandals and the doping affair in the Tour de France show that sleazy dealings can stain the most venerable athletic spectacle. "For the Good of the Game" is FIFA'S official motto. The next few months should show whether it rings true.
