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【B1】______workers’ productivity. Instead, the studies ended【B2】______giving their name to the "Hawthorne effect", the extremely influential idea that the very【B3】______of being experimented upon changed subjects’ behavior.
The idea arose because of the【B4】______behavior of the women in the plant. According to 【B5】______of the experiments, their hourly output rose when lighting was increased, but also when it was dimmed. It did not【B6】______what was done in the experiment;【B7】______something was changed, productivity rose. A(n)【B8】______that they were being experimented upon seemed to be【B9】______to alter workers’ behavior【B10】______itself.
After several decades, the same data were【B11】______to econometric analysis. Hawthorne experiments has another surprise in store.【B12】______the descriptions on record, no systematic【B13】______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【B14】______interpretations of what happened.【B15】______, lighting was always changed on a Sunday. When work started again on Monday, output【B16】______rose compared with the previous Saturday and【B17】______to rise for the next couple of days. 【B18】______, a comparison with data for weeks when there was no experimentation showed that output always went up on Mondays. Workers【B19】______to be diligent for the first few days of the week in any case, before【B20】______a plateau and then slackening off. This suggests that the alleged "Hawthorne effect" is hard to pin down.
【B16】
选项
A、duly
B、accidentally
C、unpredictably
D、suddenly
答案
A
解析
考查形容词辨析。本句提到,当周一工人开始工作时,生产率与周六相比______上升了。文章前面已经提到照明和生产率之间是有关系的,可见此处选择A.duly“如期地”,这是一种规律性变化,而不可能是某一次实验偶发的结果。accidentally“偶然地”,unpredictably“不可预测地,出乎意料地”,suddenly“突然地”,均不能体现出规律性变化。
