问题     Whenever I hear a weather report declaring it’s the hottest June 10 on record or whatever, I can’t take it too seriously, because "ever" really means "as long as the records go back" , which is only as far as the late 1800s. Scientists have other ways of measuring temperatures before that, though—not for individual dates, but they can tell the average temperature of a given year by such proxy measurements as growth marks in corals, deposits in ocean and lake sediments, and cores drilled into glacial ice. They can even use drawings of glaciers as there were hundreds of years ago compared with today.
    And in the most comprehensive compilation of such data to date, says a new report from the National Research Council, it looks pretty certain that the last few decades have been hotter than any comparable period in the last 400 years. That’s a blow to those who claim the current warm spell is just part of the natural up and down of average temperatures—a frequent assertion of the global—warming-doubters crowd.
    The report was triggered by doubts about past-climate claims made last year by climatologist Michael Mann, of the University of Virginia(he’s the creator of the "hockey stick" graph AI Gore used in "An Inconvenient Truth" to dramatize the rise in carbon dioxide in recent years). Mann claimed that the recent warming was unprecedented in the past thousand years—that led Congress to order up an assessment by the prestigious Research Council. Their conclusion was that a thousand years was reasonable, but not overwhelmingly supported by the data. But the past 400 was—so resoundingly that it fully supports the claim that today’s temperatures ale unnaturally warm, just as global warming theory has been predicting for a hundred years. And if there’s any doubt about whether these proxy measurements are really legitimate, the NRC scientists compared them with actual temperature data from the most recent century, when real thermometers were in widespread use. The match was more or less right on.
    In the past nearly two decades since TIME first put global warming on the cover, then, the argument against it has gone from "it isn’t happening" to "it’s happening, but it’s natural" , to "it’s mostly natural" —and now, it seems, that assertion too is going to have to drop away. Indeed. Rep. Sherwood Boehert, the New York Republican who chairs the House Science Committee and who asked for the report declared that it did nothing to support the notion of a controversy over global warming science—a controversy that opponents keep insisting is alive. Whether President Bush will finally take serious action to deal with the warming, however, is a much less settled question. [br] What is the author’s attitude towards global warming theory?
选项 A、Negative.
B、Indifferent.
C、Favorable.
D、Neutral.
答案 C
解析 本题是观点态度题。第四段提到“…the argument against it has gone from“it isn’thappening”to“it’s happening，but it’s natural”，to“it’s mostly natural”一and now，it seems，that assertion too is going to have to drop away．”，此句为作者对全球变暖怀疑论的评价：全球变暖怀疑论者从一开始认为“全球变暖不可能发生”，到认为“全球变暖正在发生，但仍是自然现象”，这一说法还将发生改变，意味着怀疑论者可能最终还是会相信全球变暖是人为因素造成的这一事实。这也就暗示了作者是全球变暖理论的支持者，因此选C。
