Text 2 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 time 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.

中国国家药物管理部门规定,药品的化学名和通用名由国家药典和药品管理部门制定,但商品名由厂家制定。正是这后一项规定。给许多药品的改名和多名创造了条件。在我国,近几年具有多种名称的常用药品有200多种,其中有4个药名的占20%,5个药名的占25%,6个药名的占25%,7个药名的占15%,还有15%的药有10个以上的名称,有的药有20多个名称,最多的有40多个名称。所有这些具有多种名称的药都是名符其实的“换汤不换药”,基本内容不变,只是包装或个别成分改变,疗效则安全一致。这段文字意在说明:
A . 药品的商品名可由厂家自行决定
B . 我国的常用药品都具有多种商品名
C . 一药多名的现象在我国非常普遍
D . 具有多种名称的药其疗效完全一致
