Passage 25
In an attempt to improve the overall performance of
clerical workers, many companies have introduced com-
puterized performance monitoring and control systems
(CPMCS) that record and report a worker’s computer-
(5) driven activities. However, at least one study has shown
that such monitoring may not be having the desired effect.
In the study, researchers asked monitored clerical workers
and their supervisors how assessments of productivity
affected supervisors’ ratings of workers’ performance. In
(10)contrast to unmonitored workers doing the same work,
who without exception identified the most important element
in their jobs as customer service, the monitored workers and
their supervisors all responded that productivity was the
critical factor in assigning ratings. This finding suggested
(15) that there should have been a strong correlation between a
monitored worker’s productivity and the overall rating the
worker received. However, measures of the relationship
between overall rating and individual elements of perfor-
mance clearly supported the conclusion that supervisors
(20) gave considerable weight to criteria such as
attendance accuracy, and indications of customer
satisfaction.
150. It can be inferred that the author of the passage discusses “unmonitored workers”(line 10) primarily in order to
(A) compare the ratings of these workers with the ratings of monitored workers
(B) provide an example of a case in which monitoring might be effective
(C) provide evidence of an inappropriate use of CPMCS
(D) emphasize the effect that CPMCS may have on workers’ perceptions of their jobs
(E) illustrate the effect that CPMCS may have on workers’ ratings
答案是D.说来惭愧，这道题只能排除A和E,对其他三个选项毫无头绪。这道题的切入点在哪里呢，请大家指教。
