在困难的日子里

这周希望能够把OG的SC 与 OG 逻辑都能看完一编,并且把数学的概念复习完一编,每天争取能够空出来完全4个小时无干扰的安静时间来看书。

在路上的时间基本上还是用来看单词,因为发现单词一天不看就会忘记,这个时间应该是值得的,故每天基本有二个小时的时间在看单词(包括在工作中也可以用)这个工作争取能在12月底完成。


每天早上的2个小时用来看逻辑
晚上的2个小时用来看语法
阅读看看有没有可能在上班的空闲时间看看,先不安排了

lz加油~

我的建议,我觉得阅读比CR、SC更需要专注,所以阅读这种做一篇都需要较长时间的东西应该放在空闲时间能够保证的时候看,效果会更好,事半功倍。CR、SC这些反而能够在工作空暇时间看。

谢谢楼上的MM,因为我阅读前段时间已经看过一遍了,再加上这个周未打算模考一下,看看自己的距离还差多远,所以这周就心急着想先把其他的内容过一遍。

昨天看了一些语法与逻辑,大约各三十道吧,因为都已经在一年前看过二遍(中间隔了有半年没有看GMAT)所以文章很熟悉,其本上错误率在80%,现在还没有敢看新的文章,打算看完后再开始总结。

现在还不知道什么时候考呢,不知道我这水平在2月份来得及不。努力吧!!

Passage 36 (36/63)

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.

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

(B) only the synthesis rate for the mRNA of the protein involved

(C) both the synthesis and degradation rates for the mRNA of the protein involved

(D) the incidence of errors in the transcription of mRNA’s from genetic nucleotide sequences(A)

(E) the rate of activity of ribosomes in the cytoplasm of most cells

刚才在这篇文章上花了一个小时,还是没有搞懂,有没有什么大牛可以帮忙解释一下的,还有这篇文章好像很难懂啊,我看了二三遍还是很不清楚,可能基础比较差,可以帮忙解释一下吗?

请大牛或版主空的时间指点一下啊!!求助

这篇文章我做的时候感觉非常好,心想对答案一定会全对,结果很受打击只对一道,看来看去我总觉的是新东方的答案错了!请大牛帮忙看一下。

Passage 55

     Some observers have attributed the dramatic growth

   in temporary employment that occurred in the United

   states during the 1980’s to increased participation in

   the workforce by certain groups, such as first-time or

(5)  reentering workers, who supposedly prefer such arrange-

   ments. However, statistical analyses reveal that demo-

   graphic changes in the workforce did not correlate with

       variations in the total number of temporary workers.

       Instead, these analyses suggest that factors affecting.(第二题选B没有异议)

 (10)  employers account for the rise in temporary employ-

       ment. One factor is product demand: temporary

   employment is favored by employers who are adapting

to fluctuating demand for products while at the same  

 Another

(15)   factor is labor’s reduced bargaining strength, which

       allows employers more control over the terms of   (第三题选E)

       employment. Given the analyses, which reveal that

       growth in temporary employment now far exceeds the

       level explainable by recent workforce entry rates of

(20)
                
groups said to prefer temporary jobs, firms should be

discouraged from creating excessive numbers of tem-

       porary positions. Government policymakers should

       consider mandating benefit coverage for temporary

       employees, promoting pay equity between temporary

(25)   and permanent workers, assisting labor unions in orga-

       nizing temporary workers, and encouraging firms to

       assign temporary jobs primarily to employees who

       explicitly indicate that preference.

 

1. The primary purpose of the passage is to

  (A) present the results of statistical analyses and propose

     further studies.

  (B) explain a recent development and predict its

     eventual consequences.

  (C) identify the reasons for a trend and recommend

     measures to address it.

  (D) outline several theories about a phenomenon and

     advocate one of them

  (E) describe the potential consequences of implementing

     a new policy and argue in favor of that policy.

 

这道题我选的是A ,因为文章说的主要是通过分析统计得出一些观点,最后提出一些建议,我感觉C不对啊!!??

 

2. According to the passage, which of the following is true

  of the “factors affecting employers” that are mentioned

  in lines

  9-10?

  (A) Most experts cite them as having initiated the

     growth in temporary employment that occurred

     during the 1980’s.

  (B) They may account for the increase in the total

     number of temporary workers during the 1980’s.

  (C) They were less important than demographic change

     in accounting for the increase of temporary

     employment during the 1980’s.

  (D) They included a sharp increase in the cost of labor

     during the 1980’s.

  (E) They are more difficult to account for than at other

     factors involved in the growth of temporary

     employment during the 1980’s.

无异议

 

 

3. The passage suggests which of the following about the

 
                    
use of temporary employment by firms during the

  1980’s?

  (A) It enabled firms to deal with fluctuating product

demand far more efficiently than they before the

1980’s.

  (B) It increased as a result of increased participation in

     the workforce by certain demograp groups.

  (C) It was discouraged by government-mandated

     policies.

  (D) It was a response to preferences indicated by certain

     employees for more flexible working arrangements.

 
                    
(E) It increased partly as a result of workers’ reduced

     ability to control the terms of their employment.

 OK

 

4. The passage suggests which of the following about the

  workers who took temporary jobs during the 1980’s?

  (A) Their jobs frequently led to permanent positions

      within firms.

  (B) They constituted a less demographically diverse

      group than has been suggested.

  (C) They were occasionally involved in actions

     organized by labor unions.

  (D) Their pay declined during the decade in comparison

     with the pay of permanent employees.

  (E) They did not necessarily prefer temporary

     employment to permanent employment.

 

5. The first sentence in the passage suggests that the

   observers mentioned in line 1 would be most likely to

   predict which of the following?
  (A) That the number of new temporary positions would

     decline as fewer workers who preferred temporary

     employment entered the workforce.                           我选 A  正确答案是E

  (B) That the total number of temporary positions would

     increase as fewer workers were able to find

     permanent positions

  (C) That employers would have less control over the

      terms of workers’ employment as workers

      increased their bargaining strength.

  (D) That more workers would be hired for temporary

      positions as product demand increased.

  (E) That the number of workers taking temporary

     positions would increase as more workers in any

     given demographic group entered the workforce.

 

6. In the context of the passage, the word “excessive” (line

 21) most closely corresponds to which of the

 following phrases?

  (A) Far more than can be justified by worker

     preferences

 
                    
(B) Far more than can be explained by fluctuations in 我选 B  , 正确答案是A

     product demand.

  (C) Far more than can be beneficial to the success of the

     firms themselves.

  (D) Far more than can be accounted for by an expanding

     national economy.

  (E) Far more than can be attributed to increases in the

     total number of people in the workforce.

 

7. The passage mentions each of the following as an

  appropriate kind of governmental action EXCEPT

  (A) getting firms to offer temporary employment

     primarily to a certain group of people.

  (B) encouraging equitable pay for temporary and

     permanent employees

  (C) facilitating the organization of temporary workers by

     labor unions.

  (D) establishing guidelines on the proportion of   我选 D, 正确答案是A

     temporary workers that firms should employ

  (E) ensuring that temporary workers obtain benefits

     from their employers.

 

水平比较差,大牛们多指点啊!
