问题     Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn’t know for sure? That the evidence was inconclusive, the science uncertain? That the antismoking lobby was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves.
    There are upsetting parallels today, as scientists in one wave after another try to awaken us to the growing threat of global warming. The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earth’s atmosphere is definitely warming and that the problem is largely man-made. The clear message is that we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel’s report "Science never has all the answers. But science does provide us with the best available guide to the future, and it is critical that our nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions. "
    Just as on smoking, voices now come from many quarters insisting that the science about global warming is incomplete, that it’s OK to keep pouring fumes into the air until we know for sure. This is a dangerous game: by the 100 percent of the evidence is in, it may be too late. With the risks obvious and growing, a prudent people would take out an insurance policy now.
Fortunately, the White House is starting to pay attention. But it’s obvious that a majority of the president’s advisers still don’t take global warming seriously. Instead of a plan of action, they continue to press for more research—a classic case of "paralysis by analysis".
    To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic research but research alone is inadequate. If the Administration won’t take the legislative initiative, Congress should help to begin fashioning conservation measures. A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial incentives for private industry, is a promising start. Many see that the country is getting ready to build lots of new power plants to meet our energy needs. If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.
The author associates the issue of global warming with that of smoking because______.
选项 A、they both suffered from the government’s negligence
B、a lesson from the latter is applicable to the former
C、the outcome of the latter aggravates the former
D、both of them have turned from bad to worse
答案B
解析 推断题。题目问的是作者为什么将全球变暖问题和吸烟问题联系在一起。定位到第一段，作者由以前反对者不相信吸烟有害健康，直到科学证明了这件事，但结果是有很多人因吸烟而死，可知吸烟一事是个教训，作者以此来告诫世人，不要重蹈覆辙，故选B。panel的定语，that引导从句作tell的间接宾语，句意为：最近由白宫招募的，来自美国国家科学院的一个小组，告诉我们地球的大气正在变暖，而这个问题主要是人类造成的。
