第3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4题：
资料：Gone are the days of “one-size-fits-all” employee benefits programs and here come newly designed and fully customized voluntary benefits. Voluntary benefits are on longer looked at as just a few “extras”, and are now becoming part of a comprehensive benefits package. Lot's take a look at how voluntary benefits have become more customized to meet the requirements of a more particular health care consumer.
Voluntary Benefits Bolster Recruitment and Retention Efforts
It gives employees a chance to select extras that the standard health care plan doesn't offer, which can be highly attractive to today's consumers Employers can also use voluntary benefits to round out their health care plans with a menu of items that cover everything from family vision care to pet insurance. This helps companies to address the specific heath and financial needs of candidates, to help the stretch their future paychecks even further.
The Advantages of Offering Voluntary Employee Benefits
In terms of being adaptable to the needs of employees, there are very few benefits that are like voluntary plans. Voluntary plans cover many of the gaps that traditional health benefits do not cover. For example, a health care plan may require dental services for minors, but not for adults. The voluntary dental program can cover things like routine cleanings and other preventative measures that help support good oral health.
Customizing Voluntary Benefit Plans
There are several areas where voluntary benefit plans exceed the customization options of other types of wellness and financial benefits. This is a continual trend that we will see more of. Financial wellness benefits can include budgeting software, company matched savings plans, employee purchase programs, discount cards, credit union access, and even short term financing to help employees who otherwise cannot get credit to purchase things they need. Some companies offer support for buying of leasing vehicles, pay off college loans, arrange for special discounts and deals on home rentals and purchases, and even provide access to tuition for college expenses.
It can be inferred from the passage that, comparing with the traditional health benefits, voluntary plans______A.incur less cost by the company to offer benefit programs.
B.cover many of the gaps that traditional health benefits do not cover.
C.help employees who are dealing with tough personal and career matters.
D.encourage employees to stay with their companies for longer periods of time.答案：B解析：本题考查的是细节理解。
