问题     Amid a summer of record-setting heat, a new survey finds that most of Generation X’s(20世纪60年代到70年代初出生的美国人)young and middle-age adults are uninformed and unconcerned about climate change.
    Only about 5% of Gen Xers, now 32 to 52 years old, are "alarmed" and 18% "concerned" about climate change, reports the University of Michigan’s Institute for Social Research on Tuesday. Two-thirds, or 66% , of those surveyed last year said they aren’t sure global warming is happening and 10% said they don’t believe it’s occurring.
    "Most Generation Xers are surprisingly disengaged, dismissive or doubtful about whether global climate change is happening and they don’t spend much time worrying about it," said author Jon D. Miller.
    The report comes as several Obama administration officials have recently linked extreme weather to climate change. In a report last week, the National Oceanic and Atmospheric Administration cited six weather events last year and said that atmospheric changes caused by the burning of fossil fuels made Texas’ heat wave, for example, 20 times more likely than it would have been in the 1960s.
    The Generation X survey of about 3,000 adults, the fourth in a continuing series, found a small but statistically significant decline in Gen Xer’s attention to climate change. In 2011, 16% said they followed the issue very or moderately closely, down from 22% in 2009.
    Why are Gen Xers so indifferent? The report, funded by the National Science Foundation, cites climate change’s complexity, pressing economic concerns and "issue fatigue". It finds educated adults tend to be more concerned about the issue. It also finds partisan(党派的)differences; nearly half of liberal Democrats were concerned or alarmed compared to zero percent of conservative Republicans.
    Miller said he expected that, given climate change’s expected impact on future generations, parents of young children would be more concerned than those without kids.
    " Not so," he said. " Generation X adults without minor children were slightly more alarmed about climate change than were parents. The difference is small, but it is in the opposite direction than we expected. " Miller said the report suggests that while there’s broad awareness of climate change, many Gen Xers prefer to focus on more immediate issues such as jobs and schools.
We can infer from Para. 4 that the American government______.
选项 A、links extreme weather to climate change since last week
B、is concerned about the consequence of climate change
C、tries hard to inform people the influence of climate change
D、is opposed to the burning of fossil fuels in the country
答案B
解析 推理判断题。本题考查有关美国政府的细节。由原文可知，奥巴马政府的数名官员把极端天气归咎于气候变化，美国国家海洋和大气管理局也对气候变化和极端天气之间的关系进行了研究。由此可推断，美国政府对于气候变化是比较关注的，故B)“关注气候变化带来的后果”为本题答案。A)“从上周开始把极端天气和气候变化联系在一起”与原文不符，原文提及在上周发布的一个报告中，美国国家海洋和大气管理局引用例子来证明气候变化和极端天气之间的关系，但这种联系并不是从上周才开始的，故排除；C)“努力试图向人们告知气候变化的影响”在原文中并未提及，故排除；D)“反对在国内使用化石燃料”与原文不符，原文仅提出美国国家海洋和大气管理局认为化石燃料的使用导致了大气变化，但并未说明美国政府对此的态度或政策，故排除。
