问题     Whether you’re a New Jersey mall rat or a farmer in India, being poor can exhaust your smarts.
    The findings indicate that an【C1】______need— making rent, getting money for food—tugs at the attention so much that it can【C2】______the brainpower of anyone who experiences it, regardless of innate intelligence or【C3】______. As a result, many social【C4】______programs set up to help the poor could backfire(have an undesired effect)by adding more【C5】______to their lives.
    There’s a widespread tendency to【C6】______that poor people don’t have money because they are lazy,【C7】______or just not that sharp, said study coauthor Sendhil Mullainathan. "Our【C8】______was quite different: It’s not that poor people are any different from rich people, but that being poor【C9】______itself has an effect."
    Mullainathan wanted to find out how those psychologically【C10】______situations affected their overall mental【C11】______. To do so, the researchers traveled to India and【C12】______464 sugar cane farmers before and after a harvest. Sugar cane farmers get paid only once a year. One month before harvest time, they are【C13】______for cash; one month after harvest, they’re flush with【C14】______.
    The farmers took tests before and after harvest. When money was running low, they performed【C15】______on the IQ test and took slightly longer to answer questions on the test than they did when【C16】______wasn’t a problem.
    The drop was【C17】______—about 9 IQ points. The research lends support to the idea that many behaviors【C18】______to being poor—using less preventive healthcare, having higher obesity rates, be ing less【C19】______parents and making poor financial decisions—may be caused by【C20】______rather than the other way around.
【C2】
选项 A、diminish
B、ensure
C、strengthen
D、enlarge
答案A
解析 上文提及…tugs at attention(……拖住人们的注意力)，因此会使人的智能受到影响。本句是对文章首段主旨(贫穷使你的智能衰竭)的具体说明。——the brainpower对应主旨中的exhaust your smarts(使你的智能衰竭)。因此空格处填入的词应跟exhaust(使……衰竭)意思相近，故选A项diminish“减少”。
