问题     In 1924 America’s National Research Council sent two engineers to supervise a series of experiments at a telephone-parts factory called the Hawthorne Plant near Chicago. It hoped they would learn how stop-floor lighting【C1】______workers’ productivity. Instead, the studies ended【C2】______giving their name to the "Hawthorne effect", the extremely influential idea that the very【C3】______of being experimented upon changed subjects’ behavior.
    The idea arose because of the【C4】______behavior of the women in the plant. According to 【C5】______of the experiments, their hourly output rose when lighting was increased, but also when it was dimmed. It did not【C6】______what was done in the experiment;【C7】______something was changed, productivity rose. A(n)【C8】______that they were being experimented upon seemed to be【C9】______to alter workers’ behavior【C10】______itself.
    After several decades, the same data were【C11】______to econometric analysis. Hawthorne experiments has another surprise in store.【C12】______the descriptions on record, no systematic【C13】______was found that levels of productivity were related to changes in lighting.
    It turns out that the peculiar way of conducting the experiments may have led to【C14】______interpretations of what happened.【C15】______, lighting was always changed on a Sunday. When work started again on Monday, output【C16】______rose compared with the previous Saturday and【C17】______to rise for the next couple of days. 【C18】______, a comparison with data for weeks when there was no experimentation showed that output always went up on Mondays. Workers【C19】______to be diligent for the first few days of the week in any case, before【C20】______a plateau and then slackening off. This suggests that the alleged "Hawthorne effect" is hard to pin down.
【C12】
选项 A、contrary to
B、consistent with
C、parallel with
D、peculiar to
答案A
解析 考查上下文理解及短语辨析。文章后面提到没有证据能证明照明情况能影响生产率，而这个结论和上文中对实验的描述是相悖的。因此选A．contrary to，意为“与…相反”。consistent with“与…一致”，parallel with“与…平行”，peculiar to“为…所特有”，均不符合语境。
