【单选题】The questions in this group are based on the content of a passage.After reading the passage, choose the best answer to each question.Answer all questions following the passage on the basis of what is stated or implied in the passage.
Although hard statistics are difficult to come by, there is substantial anecdotal evidence that use of performance-enhancing drugs, or doping, is rampant in professional sports. Of perhaps greater significance to society are the estimated 1.5 million amateur athletes who use steroids, either to improve their appearance or to emulate the performance of their favorite professional athletes. This chemical epidemic is a pernicious threat to both the nation’s health and our collective sense of "fair play."
Nonprescription anabolic steroids have been illegal in the United States since 1991, and most professional sports leagues have banned them since the 1980s. These bans are partly a matter of fairness--a talented athlete trained to the peak of her ability simply cannot compete with an equivalent athlete using steroids--but also based on issues of health.Anabolic androgenic steroids ("anabolic" means that they build tissues; "androgenic" means that they increase masculine traits) have been linked to liver damage, kidney tumors, high blood pressure, balding, and acne. They function by increasing the body’s level of testosterone, the primary male sex hormone. In men, this dramatic increase in testosterone can lead to the shrinking of testicles, infertility, and the development of breasts; in women, it can lead to the growth of facial hair and permanent damage to the reproductive system. Steroids have also been linked to a range of psychological problems, including depression and psychotic rage.
The punishments for getting caught using steroids are severe, and the serious health consequences are well documenteD、Despite this, millions of professional and amateur athletes continue to use performance-enhancing drugs. Why is this
One clear pattern is that many athletes will do whatever it takes to get an edge on the competition. Since the 1950s, Olympic athletes have played a cat-and-mouse game with OlympicCommittee officials to get away with doping, because the drugs really do work.Athletes who dope are simply stronger and faster than their competitors who play fair. Professional athletes in football and baseball have found that steroids and human growth hormone can give them the edge to score that extra touch-down or home run, and in the modern sports market, those results can translate into millions of dollars in salary. For the millions of less talented athletes in gyms and playing fields across the country, drugs seem like the only way to approach the abilities of their heroes in professional sports.
The other clear pattern, unfortunately, is that it has been all too easy for abusers to get away with it. Steroid abuse is often regarded as a "victimless crime." One of the favored ways to trick the testers is to use "designer" steroids. There are thousands of permutations of testosterone, such as THG, that can be produced in a laB、Chemists have discovered that they can create new drugs that produce androgenic effects but do not set off the standard doping tests. Other methods have been to use the steroids but stop a few weeks before testing, to use other chemicals to mask the traces of steroids, or to switch in a "clean" sample of urine at the testing site. Other athletes use steroid precursors, such as androstene-dione, that have androgenic effects similar to those of steroids but are not illegal because they are not technically steroids.

Since the 1970s, a multitude of scientists from the fields of climatology, oceanography, and biology have been warning the governments of the world that unless human societies reduce their emissions of "greenhouse gases"--gases such as carbon dioxide and methane that increase the capacity of the atmosphere to retain heat--world-wide global warming caused by these gases will result in catastrophic consequences for people and the environment. InDecember 1997, a group of delegates from over 100 nations gathered together in Kyoto, Japan, in order to work out the details of the Kyoto Protocol to the United Nations FrameworkConvention onClimateChange, the most comprehensive international effort to date to combat the rise of greenhouse gas emissions.
The chief goal of the Kyoto Protocol is for industrialized nations to reduce their emissions of green-house gases by 5.2 percent compared to 1990 levels. The gases targeted by the protocol are carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, HFCs, and PFCs. The protocol contains some provisions for developing nations, but as the per-capita emissions of greenhouse gases from these nations are much lower than those of industrialized nations, the majority of the reductions called for by the protocol come from theEuropean Union (8 percent reduction from 1990 levels), the United States (7 percent reduction), and Japan (6 percent reduction).
Proponents of the Kyoto Protocol maintain that although it is not sufficient by itself to halt global warming, it represents an important first step toward a sustainable global economy. These proponents argue that most of the reductions in green-house gases can be achieved through improvements in efficiency and the use of cleaner fuels. While they concede that the provisions of the protocol may slow economic growth in affected nations, they maintain that the potential economic costs are far outweighed by the benefits of avoiding the ravages of global warming, which they say could include rising sea levels, erratic weather patterns, and long-term reductions in biodiversity.
Critics of the Kyoto Protocol argue that it is unnecessary, unfair, and too costly to implement. It is unnecessary, they maintain, because the scientific community is still divided on the questions of whether global warming is happening and, if it is, whether human activity is the cause. They say it is unfair because the provisions primarily limit the emissions growth of industrialized nations while giving free rein to developing nations such as India, which actually emit more greenhouse gases than many industrialized nations, and that this situation will give the developing nations an economic edge in the global marketplace. Furthermore, they argue, the costs of switching fuels and limiting energy use will severely damage the economy, and the negative effects of this economic depression will outweigh any theoretical gains to be had by delaying global warming.
According to the passage, what is the likely response of a supporter of the Kyoto Protocol to the argument that implementation of the protocol will cause undue economic hardship for industrialized nations
A、It is only fair for industrialized nations to pay the majority of the expenses for enforcing the protocol, since industrialized nations have the majority of the money in the worlD、
