第1题：
According to Federal health officials ,the fact that more West Nile cases have been reported indicates that
[A] more states are affected.
[B] the average age dropped drastically.
[C] health officials are more alert to the disease.
[D] the epidemic season began a month earlier.
正确答案：C
52.C 【精析】该题为细节题。第二段第四句“Federal. health officials are still trying to figure out why, but say they may be finding more West Nile precisely because they're on the lookout for it.”中的“be on the lookout for something”意为“注意，留心，警戒”，由此我们知道，联邦公共卫生官员仍然在寻找病毒蔓延的原因，但是认为因为他们对病毒的警惕性高，因此才可能会发现更多的感染者。故只有C项的表述正确。 -

第5题：
Text 1 In an essay entitled“Making It in America”,the author Adam Davidson relates a joke from cotton country about just how much a modern textile mill has been automated:The average mill has only two employees today,“a man and a dog.The man is there to feed the dog,and the dog is there to keep the man away from the machines.”Davidson's article is one of a number of pieces that have recently appeared making the point that the reason we have such stubbornly high unemployment and declining middleclass incomes today is also because of the advances in both globalization and the information technology revolution,which are more rapidly than ever replacing labor with machines or foreign worker.In the past,workers with average skills,doing an average job，could earn an average lifestyle.But，today，average is officially over.Being average just won't earn you what it used to.It can't when so many more employers have so much more access to so much more above average cheap foreign labor,cheap robotics,cheap software,cheap automation and cheap genius.Therefore,everyone needs to find their extra—their unique value contribution that makes them stand out in whatever is their field of employment.Yes,new technology has been eating jobs forever,and always will.But there's been acceleration.As Davidson notes,“In the 10 years ending in 2009,U.S.factories shed workers so fast that they erased almost all the gains of the previous 70 years;roughly one out of every three manufacturing jobs—about 6 million in total—disappeared.”There will always be change—new jobs,new products,new services.But the one thing we know for sure is that with each advance in globalization and the I.T.revolution,the best jobs will require workers to have more and better education to make themselves above average.In a world where average is officially over,there are many things we need to do to support employment,but nothing would be more important than passing some kind of G.I.Bill for the 21st century that ensures that every American has access to posthigh school education.
The quotation in Paragraph 4 explains that_____A.gains of technology have been erased
B.job opportunities are disappearing at a high speed
C.factories are making much less money than before
D.new jobs and services have been offered答案：B解析：推理题【命题思路】虽然从形式上来说，本题考查的是对一个句子意思的理解，但实际上这是作者引用Davidson的话来说明他在上文提出的论点，因此这道题的解题关键在于把握引用句子前面的部分。【直击答案】根据题干定位到第四段，首句指出作者提出的观点：新技术不断吞噬工作，而且现在的速度在加快。后面引用的话语是对这个论点的具体说明，选项B中的“job opportunities”与原文的“job”相对应，“are disappearing at a high speed”与原文“has been eating jobs”以及“there's been acceleration”相对应，故为正确答案。【干扰排除】A项和C都是对引号中的局部信息设置的干扰项，均属于张冠李戴。D项是无中生有信息。 -
第6题：
资料：Placing the right type of workers in close proximity to each other can generate up to a 15 percent increase in organizational performance，according to the study from Cornerstone On Demand，a provider of cloud-based learning and talent-management software，and researchers at Harvard Business School in Massachusetts. For businesses with 2，000 employees, this translates into an additional $1 million in profit each year，the study said.
For the study，researchers examined data from a two-year period of more than 2，000 employees working at a large technology company with locations in the U.S. and Europe. The study’s authors separated workers into three different categories based on the work they produced：
Productive： These employees are very productive，but don’t always produce quality work.
Quality：These workers produce work of superior quality，but aren’t always productive.
Generalists： These employees are average in terms of both productivity and quality.
The researchers defined productivity by how long it takes an employee to finish a task，and effectiveness by how often employees need to ask a co-worker for help completing a task.
What might be discussed later？A.The reason for better performances
B.The impact of seating employees close to each other
C.The findings of seating different categories of people
D.All above答案：C解析：本题考查的是推理判断。
【关键词】discussed；later
【主题句】最后1自然段The researchers defined productivity by how long it takes an employee to finish a task，and effectiveness by how often employees need to ask a co-worker for help completing a task.研究人员通过员工完成一项任务需要多长时间来定义工作效率，通过员工为完成任务每隔多长时间向同事寻求帮助来定义工作有效性。
【解析】本题的问题是“接下来可能会讨论什么”。 A选项“更好表现的原因”；B选项“员工就近落座的影响”；C选项“不同类别的员工座位的发现”；D选项“以上都是”。通读全文，文章开头处由一项研究引入，说明合适的坐位安排会使组织绩效提高，继而介绍研究背景，将员工划分为三种类型。接下来，应该是会具体讲述哪些员工坐在一起绩效更好的关于不同类别员工座位的发现，因此C选项更符合题意。A选项过于笼统，且应当跟在第1自然段之后进行论述，而B选项在第1自然段进行过讨论，因此C选项正确。 -

第23题：
单选题A recent study of an insurance company’s underwriters indicated that those who worked in pleasant physical surroundings were 25 percent more productive than their peers in unpleasant physical surroundings. Objective criteria for evaluating job performance included caseload and complexity of cases. This shows that improving workers’ environments increases those workers’ productivity. Which of the following, if true, most seriously weakens the conclusion above?AOn average, less-productive employees spend no fewer hours per day at their workstations than do their more-productive peers.
BUnpleasant surroundings give employees less motivation to work hard than more pleasant surroundings do.
CThe more-productive employees are generally rewarded with pleasant office space.
DMore-productive employees do not work any more hours than their less-productive peers.
EPeer pressure discourages employees in crowded, unpleasant surroundings from making phone calls to their own family members during work time.
正确答案： B解析：
文段由一项研究的结果：在令人舒适的工作环境中的员工比处于不太舒适的工作环境中的同时的效率高25%，得出结论：改善工人的工作环境能提高他们的效率，文中没有提到工作效率高和环境好的因果关系，所以如果工作效率高导致了工作环境的变好，那么该假设会得到削弱，故本题应选C项。
