OG11 Verbal Review 48

string

In an attempt to improve the overall performance of clerical workers，many companies have introduced computerized performance monitoring and control systems(CPMCS)that record and report a worker's computer-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 worker’s performance. In 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 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 performance clearly supported the conclusion that supervisors gave considerable weight to criteria such as attendance, accuracy, and indications of customer satisfaction. It is possible that productivity may be a ＂hygiene factor"；that is，if it is too low，it will hurt the overall rating．But the evidence suggests that beyond the point at which productivity becomes ＂good enough，"higher productivity per se is unlikely to improve a rating.

Questions 47-51 refer to the passage a hove.

48．  It can be inferred that the author of the passage discusses＂unmonitored workers＂(1ine 12)primarily in order to

(A)  compare the ratings of these workers with the ratings of monitored workers

(B)  provide an example or 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D，我觉得E也对...

两个的区别就是

 the monitored workers and their supervisors all responded that
        

who without exception identified the most important element as

=the effect that CPMCS may have on workers’ perceptions

因为CPMCS对monitored workers and their supervisors 和unmonitored workers and their supervisors 的观点影响是直接的，有和没有 workers and their supervisors 的观点就不一样，而对workers’ ratings  影响是最后根据However，之后的那段supervisors 的实际做法来推断出来的－It is possible that
