问题     Americans’ pride and faith of their economic system,【C1】________that it provides opportunities for all citizens to have good lives, are【C2】________by the【C3】________that poverty persists in many parts of the country.
    Government anti-poverty efforts have made some progress but have not eradicated the problem. 【C4】________, periods of strong economic growth, which bring more jobs and higher wages, have【C5】________poverty but have not【C6】________it entirely.
    The federal government【C7】________poverty line as a minimum【C8】________of income【C9】________for basic maintenance of a family of four. This amount may fluctuate【C10】________the cost of living and the location of the family. In 1998, a family of four with an annual income below $16,530 was classified【C11】________living in poverty.
    The percentage of people living below poverty line dropped from 22.4 percent in 1959 to 11.4 percent in 1978. But【C12】________, it has fluctuated in a fairly narrow range. In 1998, it stood at 12.7 percent.
    【C13】________, the overall figures mask much more severe pockets of poverty. In 1998, more than one-quarter of all African-Americans lived in poverty; though【C14】________high, that figure did represent an improvement from 1979 when 31 percent of blacks were officially classified as poor.
    There are【C15】________estimations on the accuracy of official poverty figures. Some analysts have suggested that the official poverty figures【C16】________the real【C17】________of poverty because they measure only cash income and exclude certain government assistance programs such as Food Stamps. Others point out, however, that these programs【C18】________cover all of a family’s food or health care needs.【C19】________others point out that people at the poverty line sometimes receive cash income from【C20】________work and in the underground sector of economy which is never recorded in official statistics.
【C12】
选项 A、from now on
B、then
C、since then
D、long before
答案C
解析 本填空考查惯用词组，并且这些词组都表示时间关系。填空所在的原文句子中有一系列的时间线索，这些时间线索是明显衔接的，D项long before(很久以前)就完全不合适了；A项from now on(从现在开始)也不对，因为这里没有now的概念；再加上本填空之后的原文句子的信息为it has fluctuated in a fairly narrow range，使用了完成时态，只有C项since then是对的，所以最佳答案为C项since then。
