问题     "A better, richer and happier life for all our citizens." That’s the American【C1】______. In practice, it means living in a spacious, air-conditioned house, owning a car or three and maybe a boat or a holiday home, not to mention flying off to【C2】______destinations.
    The trouble【C3】______this lifestyle is that it consumes a lot of power. If everyone in the world started living like wealthy Americans, we【C4】______need to generate more than 10 times【C5】______energy each year. And【C6】______, in a century or three, we all expect to be【C7】______by an army of robots and fly into space on holidays, we are going to need a vast amount more. Where are we going to get so much power from?
    It is clear that continuing to rely on【C8】______fuels will have catastrophic results, because of the dramatic warming effect of carbon dioxide. But alternative power sources will affect the climate too. For now, the climatic effects of "clean energy" sources are trivial【C9】______those from greenhouse gases, but if we keep on using ever more power over the coming centuries, they will become ever more【C10】______.
【C9】
选项 A、according to
B、based on
C、such as
D、compared with
答案D
解析 空白处前面一句的意义是“清洁能源对气候的影响不大”，而后面的几个词的含义是“温室效应对气候的影响”，两者之间不存在“根据”(according to)或“包括”(such as)的关系，也没有“基于”的可能性，而compared with说明：与“温室效应对气候的影响”相比，前者就是小巫见大巫了。这是compared with(to)的典型用法之一。
