1、大学六级-132 及答案解析(总分:693.00,做题时间:90 分钟)一、BPart Writing(总题数:1,分数:106.00)1.假如你是李静,你想向校长申请参加西部大开发,你要给校长写一封信,信的内容包括: 1表达自己想要参加西部大开发的愿望; 2简要说明自己的理由。(分数:106.00)_二、BPart Reading (总题数:1,分数:70.00)BA Dose of Reality/BBMajor Reality Check/BWhen the pain reliever Vioxx was Withdrawn from the market last fall after
2、 the announcement that it increased patients risk of heart attacks and strokes, millions of Americans panicked. The sometimes sensationalized headlines didnt help. People wondered, “Should I trust my doctor?“ “Could a medication that I thought would help me actually kill me?“ “Is our drug safety sys
3、tem broken?“Suddenly, ads for the drug were replaced with ads looking for Vioxx “victims“. Law firms across the nation began recruiting anyone who had ever taken the drug as plaintiffs (原告) for class-action (公诉) suits. Merck, the company that developed the drug, could be liable for billions of dolla
4、rs, making it one of the costliest liability cases ever, No surprise, then, that Mercks stock plummeted(垂直落下) 40 percent in just six weeks.But the real cost was even greater. Not only did patients stop taking Vioxx but, doctors say, many people stopped taking their other medicines, toosometimes putt
5、ing their health at serious risk.Vioxx was the first pebble in the pharmaceutical rock slide. Soon, accusations about a spate of other drugs were making headlines, including all COX-2 inhibitors which, like Vioxx, relieve pain. The charges didnt stop there. The FDA was accused of simply robber-stamp
6、ing new drugs; drug companies. were blamed for hiding information about unsafe products; .and the efficacy(功效) of clinical trials that did not reveal how large numbers of people would react was questioned. But one question that was rarely asked could determine whether or not pharmaceutical companies
7、 continue to develop and produce breakthrough medications that can save or extend lives and help people live without pain. The question: do Americans expect drugs to be risk-free? And, if someone suffers a bad reaction, will lawyers rather than doctors be the first people we call?BPanic over Pills:
8、Overreaction?/BDuring the ten-year period between 1994 and 2004, the FDA approved 321 completely new drugs (this doesnt include approvals for changes to existing medicines), bringing the total to more than 10,000 drug products on the market. During that same period, eight drugs were withdrawn for re
9、asons of safety, such as the diet drug fenfluramine (fen-phen, associated with heart-valve disease) and the allergy drug Seldane (linked to heart arrhythmias). But the Vioxx recall created a shock wave for the American consumer like no other. Many people had come to depend on their “meds“, and they
10、expected them to be safe, too, especially when they cost so much. Prescription drugs account for, some Say, the fastest growing segment (about one- tenth) of all health expenditures, with some specialty drugs costing hundreds of dollars per dose.“With Vioxx, the real shock and outrage came when ther
11、e was a suggestion that people in authority may have known about these harmful side effects and not shared them with doctors or the public,“ says Anne Woodbury, chief health advocate for the Center for Health Transformation, a think tank founded by Newt Gingrich. It made people question their faith
12、in the pharmaceutical industry, federal regulators and physiciansthose we trust to make sure our drugs are safe. Before, taking a newly prescribed pill with a slug of water was as routine as brushing your teeth. For many people, this is no longer the case.People have reason to worry. In clinical tri
13、al data submitted to the FDA, Vioxx showed no connection to heart problems. The drug was approved in May 1999. But after Vioxx hit the market and grew in popularity, heart problems were revealed lots of them. Tens of thousands of people may have been affected, and Merck was accused of hiding that in
14、formation.“The system is not perfect,“ comments Marianne J. Legato, MD, professor of clinical medicine at Columbia University College of Physicians and Surgeons in New York City. “Sometimes a company may not want to show data that are negative till they really know whats going on. But its ridiculous
15、 to suggest that they would suppress things willy-nilly, because if a drug is going to cause severe side effects, its not in their best interest to hide that.“BHow Side Effects Emerge/BHow can dangerous side effects take years, or even decades, to become known? A new drug is first tested on animals.
16、 If the results indicate that its likely to be both safe and effective, the company applies to the FDA for permission to begin testing it in humans. Human studies have three phases: to evaluate safety, to determine effectiveness, end to verify safety, dosage and effectiveness. Although a trial may e
17、xtend as long as five years and often includes between 3,0DO and 10,000 people, each participant may only receive the medication for a period of weeks or months. Statistically, rare and dangerous side effects may not emerge until millions of people have used the drug, after FDA approval.So why dont
18、we test drugs on more people and for longer periods of time? For one thing, quicker approvals may save lives, as with drugs for AIDS or a vaccine for a newly emerging flu pandemic. Another reason is cost. “It already costs a billion dollars to get a drag from an idea to the market,“ rays Corr. “If w
19、e had to study a million patients before we took a drug to market, there would never be another drug.“BMonitoring after Approval/BAfter a drug is approved, it is subject to post-market surveillance(监督). The FDA analyzes reports of “adverse events“, or drug side effects, which come from the industry,
20、 from ongoing clinical trials and through its Mad Watch program, to which consumers, physicians, pharmacists and other health professionals voluntarily report problems.Negative reports about a drug thats on the market can yield crucial new information. “Clinical trials that are negative are, many ti
21、mes, just as important as the trials that show positive results,“ says Marvin Lipman, MD, chief medical adviser for Consumer Reports. Legislation was introduced in both the House and Senate in October 2004 to establish a registry of all clinical trials and their results. “We are the most regulated i
22、ndustry in the world,“ rays Corr. “And frankly, thats how it should be. If there is a problem with a drug, We want to know about it sooner rather than later.“Consumers may know sooner too. In February the FDA announced the creation of an independent Drug Safety Oversight Board to provide expanded an
23、d faster drug-safety information to doctors and patients. While there will always be risks, the Public may be better equipped to judge and act on them.“We still need to be willing to take personal responsibility for assessing the risk-benefit ratio of a medication,“ says Legato. “Yes, you have to be
24、 completely informed to do it. And, yes, its complex. But if we dont do this, ifs like going back to the Middle Ages when there were no risks, except of dying by the age of 26. We have nearly doubled life expectancy since the beginning of the 20th century. That did not happen by accident. Prescripti
