2011年六月英语六级考试模拟练习题答案(2)_第4页

    
    Passage One
    
    Questions 52 to 56 are based on the following passage.
    
    You’re in trouble if you have to buy your own brand-name prescription drugs. Over the past decade, prices leaped by more than double the inflation rate. Treatments for chronic conditions can easily top $2,000 a month-no wonder that one in four Americans can’t afford to fill their prescriptions. The solution? A hearty chorus of “O Canada.” North of the border, where price controls reign, those same brand-name drugs cost 50% to 80% less.
    
    The Canadian option is fast becoming a political wake-up call, “If our neighbors can buy drugs at reasonable prices, why can’t we? Even to whisper that thought provokes anger. “Un-American!” And-the propagandists’ trump card (王牌)—“Wreck our brilliant health-care system.” Super size drug prices, they claim, fund the research that sparks the next generation of wonder drugs. No sky-high drug price today, no cure for cancer tomorrow. So shut up and pay up.
    
    Common sense tells you that’s a false alternative. The reward for finding, say, a cancer cure is so huge that no one’s going to hang it up. Nevertheless, if Canada-level pricing came to the United States, the industry’s profit margins would drop and the pace of new-drug development would slow. Here lies the American dilemma. Who is all this splendid medicine for? Should our health-care system continue its drive toward the best of the best, even though rising numbers of patients can’t afford it? Or should we direct our wealth toward letting everyone in on today’s level of care? Measured by saved lives, the latter is almost certainly the better course.
    
    To defend their profits, the drug companies have warned Canadian wholesalers and pharmacies (药房) not to sell to Americans by mail, and are cutting back supplies to those who dare.
    
    Meanwhile, the administration is playing the fear card. Officials from the Food and Drug Administration will argue that Canadian drugs might be fake, mishandled, or even a potential threat to life.
    
    Do bad drugs fly around the Internet? Sure-and the more we look, the more we’ll find, But I haven’t heard of any raging epidemics among the hundreds of thousands of people buying crossborder.
    
    Most users of prescription drugs don’t worry about costs a lot. They’re sheltered by employee insurance, owing just a $20 co-pay. The financial blows rain, instead, on the uninsured, especially the chronically ill who need expensive drugs to live, This group will still include middle-income seniors on Medicare, who’ll have to dig deeply into their pockets before getting much from the new drug benefit that starts in 2006.
    
    52. What is said about the consequence of the rocketing drug prices in the U.S.?
    
    A) A quarter of Americans can’t afford their prescription drugs.
    
    B) Many Americans can’t afford to see a doctor when they fall ill.

    D) The inflation rate has been more than doubled over the years.

    A) encouraging people to buy prescription drugs online
    
    B) extending medical insurance to all its citizens
    
    C) importing low-price prescription drugs from Canada
    
    D) exercising price control on brand-name drugs
    
    54. How do propagandists argue for the U.S. drug pricing policy?
    
    A) Low prices will affect the quality of medicines in America.
    
    B) High prices are essential to funding research on new drugs.
    
    C) Low prices will bring about the anger of drug manufacturers.
    
    D) High-price drugs are indispensable in curing chronic diseases.
    
    55. What should be the priority of America’s health-care system according to the author?
    
    A) To resolve the dilemma in the health-care system.
    
    B) To maintain America’s lead in the drug industry.
    
    C) To allow the vast majority to enjoy its benefits.
    
    D) To quicken the pace of new drug development.
    
    56. What are American drug companies doing to protect their high profits?
    
    A) Labeling drugs bought from Canada as being fakes.
    
    B) Threatening to cut back funding for new drug research.
    
    C) Reducing supplies to uncooperative Canadian pharmacies.
    
    D) Attributing the raging epidemics to the ineffectiveness of Canadian drugs.
Passage Two
    
    Questions 57 to 61 are based on the following passage.
    
    When imaginative men turn their eyes towards space and wonder whether life exist in any part of it, they may cheer themselves by remembering that life need not resemble closely the life that exists on Earth. Mars looks like the only planet where life like ours could exist, and even this is doubtful. But there may be other kinds of life based on other kinds of chemistry, and they may multiply on Venus or Jupiter. At least we cannot prove at present that they do not.
    
    Even more interesting is the possibility that life on their planets may be in a more advanced stage of evolution. Present-day man is in a peculiar and probably temporary stage. His individual units retain a strong sense of personality. They are, in fact, still capable under favorable circumstances of leading individual lives. But man's societies are already sufficiently developed to have enormously more power and effectiveness than the individuals have.
    
    It is not likely that this transitional situation will continue very long on the evolutionary time scale. Fifty thousand years from now man's societies may have become so close-knit that the individuals retain no sense of separate personality. Then little distinction will remain between the organic parts of the multiple organism and the inorganic parts (machines) that have been constructed by it. A million years further on man and his machines may have merged as closely as the muscles of the human body and the nerve cells that set them in motion.
    
    The explorers of space should be prepared for some such situation. If they arrive on a foreign planet that has reached an advanced stage (and this is by no means impossible), they may find it being inhabited by a single large organism composed of many closely cooperating units.
    
    The units may be “secondary” — machines created millions of years ago by a previous form of life and given the will and ability to survive and reproduce. They may be built entirely of metals and other durable materials. If this is the case, they may be much more tolerant of their environment, multiplying under conditions that would destroy immediately any organism made of carbon compounds and dependent on the familiar carbon cycle.
    
    Such creatures might be relics(遗物) of a past age, many millions of years ago, when their planet was favorable to the origin of life, or they might be immigrants from a favored planet.
