#1 FEIFEI 91
91. Leachate is a solution, frequently highly contaminated, that develops when water permeates a landifill’s site. If and only if the landfill’s capacity to hold liquids is exceeded does the leachate escape into the environment, generally in unpredictable quantities. A method must be found for disposing of leach ate. Most landfill leachate is sent directly to sewage treatment plants, but not all sewage plants are capable of handling the highly contaminated water.

Which one of the following can be inferred from the passage?
E.   If leachate does not escape from a landfill into the environment, then the landfill’s capacity to hold liquids has not been exceeded.

#2 FEIFEI 92
92. Baking for winter holidays is a tradition that may have a sound medical basis. In midwinter, when days are short, many people suffer from a specific type of seasonal depression caused by lack of sunlight. Carbohydrates, both sugars and starches, boost the brain’s levels of serotonin, a neurotransmitter that improves the mood. In this respect, carbohydrates act on the brain in the same way as some antidepressants. Thus, eating holiday cookies may provide an effective form of self-prescribed medication.

Which one of the following can be properly inferred from the passage?
D.   Some antidepressants act by changing the brain’s level of serotonin.

#3 FEIFEI 93
93. The efficiency of microwave ovens in destroying the harmful bacteria frequently found in common foods is diminished by the presence of salt in the food being cooked. When heated in a microwave oven, the interior of unsalted food reaches temperatures high enough to kill bacteria that cause food poisoning, but the interior of salted food does not. Scientists theorize that salt effectively blocks the microwaves from heating the interior.

Which one of the following conclusions is most supported by the information above?
D.   The danger of food poisoning can be lessened if salt is not used to prepare foods that are to be cooked in a microwave oven.

#4 FEIFEI 95
95. Scientific research that involves international collaboration has produced papers of greater influence, as measured by the number of times a paper is cited in subsequent papers, than has research without any collaboration. Papers that result from international collaboration are cited an average of seven times, whereas papers with single authors are cited only three times on average. This difference shows that research projects conducted by international research teams are of greater importance than those conducted by single researchers.

Which one of the following is an assumption on which the argument depends?
C.   The number of citations a paper receives is a measure of the importance of the research it reports.

#5 AA60 有点长。。
60. The following appeared as part of a recommendation by one of the directors of the Beta Company.
“The Alpha Company has just reduced its workforce by laying off fifteen percent of its employees in all divisions and at all levels, and it is encouraging early retirement for other employees. As you know, the Beta Company manufactures some products similar to Alpha’s, but our profits have fallen over the last few years. To improve Beta’s competitive position, we should try to hire a significant number of Alpha’s former workers, since these experienced workers can provide valuable information about Alpha’s successful methods, will require little training, and will be particularly motivated to compete against Alpha.”

Q.SUPPORT——可能会指出他因是不存在的来支持conclusion
【题目都看错了……脑子里全是浆糊嘛啊……】

#4 55s
P1.国际合作的论文比非国际合作的论文更有影响力，这个影响力由被后来的论文引用的次数来衡量
P2.被引用的次数较多的文章，合作作者平均有7个，引用较少的作者平均有3个
conclusion：多个作者的文章一定比单个作者的文章更有影响力
Q:ASSUMPTION——作者本身的学术背景对文章影响力没有影响
【继续错了：应该是projects也符合这个基于引用次数的判断标准。PO4要时刻牢记】

1.超时 LA是一种污水（solution看了半天）是水穿过垃圾后的污水，这种污水是当垃圾没有足够的容积收容这些液体的时候会流出意想不到多的这种液体，必须有办法来解决这些污水，通常我们把它排到下水道里，但是下水道也没有足够的空间容纳这些污水
得到：想不到

2.吃糖是冬天的一种习俗同时也有一定的药物效果，在冬天很多人因为缺少阳光的照射使得精神萎靡，然后C中有物质可以刺激人释放S S会使得人们更加兴奋，减少抑郁，所以吃糖会对人们产生良好的药物效果
得到：

3.食物中的盐会降低微波炉对食物总细菌的杀除效果，微波炉可以没有盐的食物达到可以杀死细菌的温度，然而无法让有盐的食物达到这个温度，科学家认为盐阻碍了热量在食物中的传导

4.超时国际合作的调查比单个调查更具有效果，因为国际调查的论文平均出现在其他类似的论文中7次，而单个调查只有3次
假设，出现的次数越多说明效果越好

A削减员工并且让其他员工早点退休。B公司利润下降，产品与A相同，所以为了增加B的利润，应该雇佣A不要了的员工，因为这些人能带来A的成功经验，不需要太多培训，并且很乐意与A抗衡。
逻辑错误：
A开出这些员工是有道理的，可能正是因为他们技术有问题。这样的话，就需要更多的培训
A的技艺和经验不一定适用于B
雇佣新员工会增加成本，有可能进一步家少利润

猜测答案：引用代表着重要性 bingo!

5.A公司开除了15%员工，鼓励早退休。
B公司产品和A相似，但利润少。
所以，雇佣A公司原来的员工---->他们经验足，A成功方法。

反驳：
1）A被开除的原因。也许就是经验不足呢。---->即，开除的不具备代表性
2）A员工不一定知道成功的原因。机密事件呢。
3）就算知道了，都是对的，那也不一定能激励B。因为公司差别，什么企业文化
难很快的改变啊什么其他的差别使得计划实施困难。

Inference: 有冬天baking习惯人总是比不吃饼干的人心情好~
我这跟答案比简直太通俗了。。。囧

3. 微波炉在加热食物杀死细菌的效率会受食物中盐含量的影响。
如果食物不含盐，则由内部加热功效低；如果食物含盐，则反之，杀菌效果不好。
Conclusion: 科学家于是下结论，盐会妨碍微波炉由内而外加热食物的效率。

4. Argument：国际合作的科学研究报告相比单一国家的研究更有影响。
Premise：国际合作的研究论文被应用次数为7，与此同时，仅在本国范围内的科研被引用次数为3.
Conclusion：国际合作的科研比单一国家的科研更有影响力。

Assumption：科研论文被引用次数直接代表了其影响力。

5. ß公司的director说
A公司去年整体裁员了15%，并鼓励员工提前退休。咱们公司现在业绩不太行，但是如果咱们能把被A公司开除的员工招募过来，这样能提高咱们的竞争力，而且他们一定会不遗余力为我们服务与A公司竞争的。

60. The following appeared as part of a recommendation by one of the directors of the Beta Company.
“The Alpha Company has just reduced its workforce by laying off fifteen percent of its employees in all divisions and at all levels, and it is encouraging early retirement for other employees. As you know, the Beta Company manufactures some products similar to Alpha’s, but our profits have fallen over the last few years. To improve Beta’s competitive position, we should try to hire a significant number of Alpha’s former workers, since these experienced workers can provide valuable information about Alpha’s successful methods, will require little training, and will be particularly motivated to compete against Alpha.”

45’
A公司会在不同部门不同level进行大范围的裁员→encourage 别的A公司员工提早退休
B公司和A公司的经营模式（只是生产的some products）相似，而且B公司近几年的盈利下降了，所以我们要雇佣A公司以前的员工，那样我们不仅能够省去培训费和时间，而且也更有动力和A公司竞争。（漏掉了原因：有经验，可以提供A公司成功的方法）
