问题     In 1924 America’s National Research Council sent two engineers to supervise a series of industrial experiments at a large 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】______to being experimented upon changed subjects’ behavior.
    The idea arose because of the【C4】______behavior of the women in the Hawthorne 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 enough to alter workers’ behavior by itself.
    After several decades, the same data were【C9】______to econometric the analysis. Hawthorne experiments has another surprise store【C10】______the descriptions on record, no systematic evidence was found that levels of productivity were related to changes in lighting.
    It turns out that peculiar way of conducting the experiments may be have let to【C11】______interpretation of what happened. 【C12】______, lighting was always changed on a Sunday. When work started again on Monday, output duly rose compared with the previous Saturday and 【C13】______to rise for the next couple of days. But a comparison with data for weeks when there was no experimentation showed that output always went up on Monday, workers【C14】______to be diligent for the first few days of the week in any case, before【C15】______a plateau and then slackening off. This suggests that the alleged "Hawthorne effect" is hard to pin down.
【C1】
选项 A、affected
B、achieved
C、extracted
D、restored
答案A
解析 文章第二句是要说明这个实验的目的。A．affect意思是“影响，感动”；B．achieve是“达成，完成”；C．extract意思是“提取，榨出”；D．restore是“恢复，重建”该句的意思是：他们想通过实验探究车间照明是如何影响工人的生产率的，从后面关于工．厂女工的描述来看也应该选affect。故答案为A。
