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.
Many Generation X parents don’t worry so much about the influence of climate change on their children because______.
选项 A、they are not aware of climate change
B、they don’t care about climate change
C、they believe the situation will be better
D、they focus more on immediate issues
答案D
解析 事实细节题。本题考查20世纪60年代到70年代初出生的已经做了父母的美国人对于气候变化对自己下一代的影响并不担忧的原因。由定位句后文可知，许多20世纪60年代到70年代初出生的美国人更为关注那些迫在眉睫的问题，如工作和教育，故D)为本题答案。A)“他们没有意识到气候变化”和原文不符，故排除；B)“他们不关心气候变化”是原文中提到的事实，但这不是这些父母不为自己子女担心的原因，故排除；C)“他们相信状况会好转”在原文中并未提及，故排除。
