又搜了一下，果然又没人问。。。。。
我太菜了。。。。。。。。。
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 workers’ 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.

1.According to the passage, before the final results of the study were known, which of the following seemed likely?

(A) That workers with the highest productivity would also be the most accurate
(B) That workers who initially achieved high productivity ratings would continue to do so consistently
(C) That the highest performance ratings would be achieved by workers with the highest productivity
(D) That the most productive workers would be those whose supervisors claimed to value productivity
(E) That supervisors who claimed to value productivity would place equal value on customer satisfaction

According to 好像是能够在原文找到确切的话的，但seemed likely 又很像infer。。。。。到底是什么啊？我很晕
我没有找到定位，就对实验现象的这句the monitored workers and their supervisors all responded that productivity was the critical factor in assigning ratings.取了非（怀疑应该跟实验反过来的，不然还要however干什么呢？），选E，然后错了，我也不知道答案C怎么出来的。。。。。。
完全没明白

However, at least one study has shown that such monitoring may not be having the desired effect.我觉得这个是主题句，可是我不知道desired effect是什么呢？是CPMCS rating跟实际supervisor rating一样吗？
唉。。。。。。。。。

还有一个问题，左想右想还是不要多发篇帖子了，就放一起吧。。。

Protein synthesis begins when the gene encoding a protein is activated. The gene’s sequence of nucleotides is transcribed into a molecule of messenger RNA (mRNA), which reproduces the information contained in that sequence. Transported outside the nucleus to the cytoplasm, the mRNA is translated into the protein it encodes by an organelle known as a ribosome, which strings together amino acids in the order specified by the sequence of elements in the mRNA molecule. Since the amount of mRNA in a cell determines the amount of the corresponding protein, factors affecting the abundance of mRNA’s play a major part in the normal functioning of a cell by appropriately regulating protein synthesis. For example, an excess of certain proteins can cause cells to proliferate abnormally and become cancerous; a lack of the protein insulin results in diabetes.

Biologists once assumed that the variable rates at which cells synthesize different mRNA’s determine the quantities of mRNA’s and their corresponding proteins in a cell. However, recent investigations have shown that the concentrations of most mRNA’s correlate best, not with their synthesis rate, but rather with the equally variable rates at which cells degrade the different mRNA’s in their cytoplasm. If a cell degrades both a rapidly and a slowly synthesized mRNA slowly, both mRNA’s will accumulate to high levels.

An important example of this phenomenon is the development of red blood cells from their unspecialized parent cells in bone marrow (bone marrow: n. 骨髓). For red blood cells to accumulate sufficient concentrations of hemoglobin (hemoglobin: n.血色素)(which transports oxygen) to carry out their main function, the cells’ parent cells must simultaneously produce more of the constituent proteins of hemoglobin and less of most other proteins. To do this, the parent cells halt synthesis of non-hemoglobin mRNA’s in the nucleus and rapidly degrade copies of the non-hemoglobin mRNA’s remaining in the cytoplasm. Halting synthesis of mRNA alone would not affect the quantities of proteins synthesized by the mRNA’s still existing in the cytoplasm. Biologists now believe that most cells can regulate protein production most efficiently by varying both mRNA synthesis and degradation, as developing red cells do, rather than by just varying one or the other.

我答案查了帖子明白了，第五题是the concentrations of most mRNA’s correlate best, not with their synthesis rate, but rather with the equally variable rates at which cells degrade the different mRNA’s in their cytoplasm的关系，可是再看看第6题的答案又是as important as.。。
不知道大家觉得矛盾发，刚刚还是一个比另一个重要呢，一会又变成一样重要了！

5.To begin to control a disease caused by a protein deficiency, the passage suggests that a promising experimental treatment would be to administer a drug that would reduce

(A) only the degradation rate for the mRNA of the protein involved

6.According to the passage, which of the following best describes the current view on the relationship between the synthesis and the degradation of mRNA in regulating protein synthesis?

((E) Degradation of mRNA is now considered to be as important as mRNA synthesis has been, and still is, believed to be.

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.

我把文章的后两段话截下来你看This finding suggested 后面是结论，但是紧跟了however，得出supported the conclusion that
然后有得出结论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.
然后把这句话取非，就是题了
下一个题，看前提，5题针对与蛋白质的缺乏 If a cell degrades both a rapidly and a slowly synthesized mRNA slowly, both mRNA’s will accumulate to high levels.这个是结论的现象，缓慢的降低高速或者缓慢合成的mrna，结果是both mRNA’s will accumulate to high levels 来治疗蛋白的缺乏
而第六题是Biologists now believe that most cells can regulate protein production most efficiently by varying both mRNA synthesis and degradation, as developing red cells do, rather than by just varying one or the other
通过这句话来看就是e选项、
你要是深研究为什么是这样，哪个是重要的？
那就是第六题的前提是regulating protein synthesis 第五题的摄提点的前提是the concentrations of most mRNA’s correlate best, regulating的包括了好多像诸如原文提到的 strings together amino acids in the order specified by the sequence of elements in the mRNA molecule等等

好谢谢每次都帮我答疑

，可我还想问下～真是好麻烦你。。。
我对第一篇的主题不大理解。。。
1.前面一段好像说CPMCS其实没什么用
可后面结论It is possible that 。。。那段又说productivity与rate的关系
到底哪个是主题呢？还是作者只是通过CPMCS引出他要说的productivity与rate的关系呢？
2.However, at least one study has shown that such monitoring may not be having the desired effect.是主题句吗？可desired effect是什么呢？是CPMCS rating跟实际supervisor rating一样吗？(莫非这个是主题？？）

edwardelric · 发表于 2010-2-23 18:30:00

感觉你说的有点乱，desired effect 我认为是第一题的c选项
文章的主题就在说however，at least one ~那个句子，后面跟的是结论This finding However, measures of the relationship between overall rating and individual elements of performance clearly supported the conclusion that .
it is possible that ...

productivity rate supervisor preformance
都是一点点的推出的关系

求助。。。。。。。。请求帮助。。。。

还想再问下～
