总结下目前CR JJ里出现的GWD（希望大家讨论下）

以下是引用遥遥G梦在2007-11-24 12:03:00的发言：

I don't agree with this argument.

 "grow" means 生存，而不是成长。理解有误,   原文意为：  the herb can survive in 有毒的环境里, 而不是成长而已。If E is correct, then the 成年的herb will die soon because it doesn't have enough histidine. But this is not what the original argument means. Hence, E is wrong.

C is the correct answer.

A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants. 这种土壤其他植物都不可能生长而且

如果象C所说其他植物都可以产生hestidine,那为什么这种herb可以在有金属的土壤生长而其他那些可以产生hestidine的植物就不可以呢？如果选C就是否定了“hestidine对这种herb有帮助“这一hypothesize,变成削弱author's statement 有另外某些原因导致这种植物可以在有毒的土里生长。变成他因削弱了 所以C不行

另外D,题目不是研究hestidine对这种herb所处的土壤带来什么影响，所以是题外话。而且题目也没有说明他会对土壤有什么积极或消极的影响，即便他真的把土壤里的毒素都消除了，也不可以支持文中的假设，因为原文是要探讨“hestidine可以renders these metals chemically inert. “ D也是错的

这是我的看法。欢迎各位指正

这题没选项的，所以只能大家讨论下他的意思

T-4-Q18
                天山-7-17

As a large corporation in small country, Hachnut wants its managers to have international experience, so each year it sponsors management education abroad for its management trainees. Hachnut has found, however, that the attrition rate of graduates from this program is very high, with many of them leaving Hachnut to join competing firms soon after completing the program. Hachnut doe use performance during the program as criterion in deciding among candidates for management positions, but both this function and the goal of providing international experience could be achieved in other ways. Therefore, if the attrition problem cannot be successfully addressed, Hachnut should discontinue the sponsorship program.

 

In the argument given, the two boldfaced portions play which of the following roles?

 

1. The first describes a practice that the argument seeks to justify; the second states a judgment that is used in support of a justification for that practice.

2. The first describes a practice that the argument seeks to explain; the second presents part of the argument’s explanation of that practice.

3. The first introduces a practice that the argument seeks to evaluate; the second provides grounds for holding that the practice cannot achieve its objective.

4. The first introduces a policy that the argument seeks to evaluate; the second provides grounds for holding that the policy is not needed.

5. The first introduces a consideration supporting a policy that the argument seeks to evaluate; the second provides evidence for concluding that the policy should be abandoned.

Which of the following most logically completes the argument?
   

A certain cultivated herb is one of a group of closely related plants that thrive in soil with high concentrations of metals that are toxic to most other plants.  Agronomists studying the herb have discovered that it produces large amounts of histidine, an amino acid that, in test-tube solutions, renders these metals chemically inert.  Possibly, therefore,
     the herb’s high histidine production is what allows it to grow in metal-rich soils, a hypothesis that would gain support if ______.
   

A.      histidine is found in all parts of the plant—roots, stem, leaves, and flowers
   
   

B.
  the herb’s high level of histidine production is found to be associated with an unusually low level of production of other amino acids
   
   

C.       others of the closely related group of plants are also found to produce histidine in large quantities
   
   

D.       cultivation of the herb in soil with high concentrations of the metals will, over an extended period, make the soil suitable for plants to which the metals are toxic
   

E.        the concentration of histidine in the growing herb declines as the plant approaches maturity

E

文中是要針對假設去做支持，但假設中，只有提到it(也就是文中所提的那種plant)

那C中的 others of the closely related group of plants不就是超出範圍??

一點小疑問，請指教!!
