问题     The enormous power tucked away in the atomic nucleus, the chemist Frederick Soddy rhapsodised in 1908, could "transform a desert continent, thaw the frozen poles, and make the whole world one smiling Garden of Eden. " Militarily, that power has threatened the opposite, with its ability to make deserts out of gardens on an unparalleled scale. Idealists hoped that, in civil garb, it might redress the balance, providing a cheap, plentiful, reliable and safe source of electricity for centuries to come. But it has not. Nor does it soon seem likely to.
    Looking at nuclear power 26 years ago, The Economist observed that the way forward for a somewhat stagnant nuclear industry was "to get plenty of nuclear plants built, and then to accumulate, a record of no deaths, no serious accidents—and no dispute that the result is cheaper energy. " It was a fair assessment; but the conclusion that the industry was "safe as a chocolate factory" proved something of a hostage to fortune. Less than a month later one of the reactors at the Chernobyl plant in Ukraine ran out of control and exploded.
    Then, 25 years later, when enough time had passed for some to be talking of a "nuclear renais-sance", it happened again. The bureaucrats, politicians and industrialists allowed their enthusiasm for nuclear power to shelter weak regulation, safety systems that failed to work and a blamable ignorance of the constructional risks the reactors faced, all the while blithely promulgating a myth of nuclear safety. In any country independent regulation is harder when the industry being regulated exists largely by government fiat. Yet, without governments private companies would simply not choose to build nuclear-power plants. This is in part because of the risks they face from local opposition and changes in government policy. But it is mostly because reactors are very expensive indeed.
    Nuclear power would be more competitive if it were cheaper. Yet despite generous government re-search-anddevelopment programmes stretching back decades, this does not look likely. Innovation tends to thrive where many designs can compete against each other, where newcomers can get into the game easily, where regulation is light. Some renewable-energy technologies meet these criteria, and are getting cheaper as a result. But there is no obvious way for nuclear power to do so. Proponents say small, mass-produced reactors would avoid some of the problems of today’s big monsters. But for true innovation such reactors would need a large market in which to compete against each other. Such a market does not exist.
    Nuclear innovation is still possible, but it will not happen apace: whales evolve slower than fruit flies. This does not mean nuclear power will suddenly go away. But the promise of a global transformation is gone.
Concerning nuclear power, the first paragraph mainly discusses its______.
选项 A、almightiness
B、safety
C、menace
D、double effect
答案C
解析 第一段共有五句话，五句话之间起承转合，逻辑衔接非常紧密。首句先借某化学家之口指出核能的威力，第二句转折指出核能在军事上带来威胁，第三句再次转折指出理想主义者对核能依然抱有幻想，末两句转承第三句指出理想主义者们的想法无法实现。由几个转折可见，第一段重在讲述核能的威胁性，[C]选项符合文意。
