题目翻译

有时候想象力是比经验更有价值的财富。缺少经验的人得以自由的想象任何可能性，并且由此可以达成一个目标而不受既定习惯和态度的限制。

Outline

I fundamentally agree with the speaker’s assertion; however, as the speaker implies, it is impossible not to overstate the comparative value of imagination.

1. One need only observe young children as they go about their daily lives to appreciate the role that pure imagination can play as an aid to accomplishing tasks.

2. The speaker’s contention also finds ample empirical support in certain forms of artistic accomplishment and scientific invention.

3. Of course, there are many notable exceptions to the rule that imagination unfettered by experience breeds remarkable insights and accomplishments.

4. On the other hand, it is important not to take this assertion about artistic and scientific accomplishment too far.

4月14日GRE写作Argument预测机经：

The following appeared in a health magazine.

"The citizens of Forsythe have adopted more healthful lifestyles. Their responses to a recent survey show that in their eating habits they conform more closely to government nutritional recommendations than they did ten years ago. Furthermore, there has been a fourfold increase in sales of food products containing kiran, a substance that a scientific study has shown reduces cholesterol. This trend is also evident in reduced sales of sulia, a food that few of the most healthy citizens regularly eat."

Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.

题目翻译

以下文字出自于一本健康杂志：“Forsythe的居民采取了更健康的生活方式。他们对于最近一项调查的回答显示，他们的饮食习惯比十年前更加贴近政府的营养建议。而且，含有kiran的食品销量增长了四倍，在一次科学研究中发现kiran是一种能够降低胆固醇水平的物质。这种趋势同样也被sulia的销量下降所证实，sulia是那些最健康的居民极少食用的食品。”

写一篇文章，阐述需要哪些具体的证据来评价这个论证过程，并解释这些证据如何削弱或强化这个论证过程。

题目分析

A. 前提[隐性]：Forsythe的居民饮食习惯越来越健康

B. 结论：the citizens of Forsythe have adopted more healthful lifestyles Forsythe的居民采取了更健康的生活方式

C. 论据：

1. Their responses to a recent survey show that in their eating habits they conform more closely to government nutritional recommendations than they did ten years ago.他们对于最近一项调查的回答显示，他们的饮食习惯比十年前更加贴近政府的营养建议

2. There has been a fourfold increase in sales of food products containing kiran, a substance that a scientific study has shown reduces cholesterol.含有kiran的食品销量增长了四倍，在一次科学研究中发现kiran是一种能够降低胆固醇水平的物质

3. This trend is also evident in reduced sales of sulia, a food that few of the most healthy citizens regularly eat.这种趋势同样也被sulia的销量下降所证实，sulia是那些最健康的居民极少食用的食品

提纲(可攻击点)

1、KIRAN销量增加是否是因为人们看中其降低胆固醇水平的功能?除了采取更健康的生活方式以外，哪些其他因素会与含有kiran的食品销量增加有更直接的关系?请举例并简述。

2、相对于十年前居民的饮食习惯(未知信息)，现在居民饮食习惯贴近政府的营养建议能否说明居民关注健康生活方式?除了关注健康，还有哪些其他可能会引起这样的变化?

3、除了采取更健康的生活方式，其他因素是否与sulia的销量下降有更直接的关系?

4、最健康的居民极少食用sulia能否有效说明sulia对健康生活有负作用?还有哪些其他解释?

5、“最健康”的居民是否是“采取健康生活方式”的那部分人?可能存在哪些不同的情况?

6、除了采取更健康的生活方式以外，其他因素是否与饮食习惯比十年前更加贴近政府的营养建议有更直接的关系?

4月14日GRE阅读逻辑预测机经：

What makes a worker ant perform one particular task rather than another? From the 1970s to the mid-1980s, researchers emphasized internal factors within individual ants, such as polymorphism, the presence in the nest of workers of different shapes and sizes, each suited to a particular task. Other elements then considered to have primary influence upon an ant’s career were its age—it might change tasks as it got older—and its genetics. However, subsequent ant researchers have focused on external prompts for behavior. In advocating this approach, Deborah Gordon cites experiments in which intervention in a colony’s makeup perturbed worker activity. By removing workers or otherwise altering the nest conditions, researchers were able to change the tasks performed by individual workers.

It can be inferred from the passage that Gordon and earlier researchers would agree with which of the following statements about worker ants?

A. Disruption of the nest can affect workers’ roles.

B. Genetics predominates over other factors in determining a worker ant’s role.

C. An individual worker’s tasks can change during its lifetime.

正确答案：C

题目解析

disruption of the nest 是在文章的后一部分在讨论DG的实验的时候提出来的新的结论，显然这个是不能被earlier researchers认可的。, researchers emphasized internal factors within individual ants, such as polymorphism, the presence in the nest of workers of different shapes and sizes, each suited to a particular task. Other elements then considered to have primary influence upon an ant’s career were its age—it might change tasks as it got older—and its genetics这里面出现的才是二者所共同认可的。所以A选项错误。 B选项，文章显然是没有说过genetics是predominate的，所有的因素没有出现一个排序，B选项错误。 既然年龄可以是一个影响因子，那么年龄变化，task也该变化，即在lifetime中task是改变的。C选项正确。

4月14日GRE数学预测机经：

According to surveys at a company, 20 percent of the employees owned cell phones in 1994, and 60 percent of the employees owned cell phones in 1998. From 1994 to 1998, what was the percent increase in the fraction of employees who owned cell phones?

A. 3%；B. 20%；C. 30%；D. 200%；E. 300%

正确答案：D
