第5题：
At a basic level, cloud computing is simply a means of delivering IT resources as( ). Almost all IT resources can be delivered as a cloud service: applications, compute power, storage capacity, networking, programming tools, even communication services and collaboration( ). Cloud computing began as large-scale Internet service providers such as Google, Amazon, and others built out their infrastructure. An architecture emerged: massively scaled,( )distributed system resources, abstracted as virtual IT services and managed as continuously configured, pooled resources. In this architecture, the data is mostly resident on( )"somewhere on the Internet" and the application runs on both the "cloud servers" and the user's browser. Both clouds and grids are built to scale horizontally very efficiently. Both are built to with stand failures of(请作答此空)elements or nodes. Both are charged on a per-use basis. But while grids typically process batch jobs, with a defined start and end point, cloud services can be continuous. What's more, clouds expand the types of resources available——file storage, databases, and Web services——and extend the applicability to Web and enterprise applications.A.entire
B.individual
C.general
D.separate答案：B解析：云计算主要是将资源看作云服务，包括应用程序、计算能力、存储容量、网络、编程工具，以及通信和协作工具。云计算最初由一些大的Internet服务提供商构建的基础设施而起步，其架构呈现出大规模、水平分布式系统资源、抽象的盯服务、管理持续配置、资源池等特性，数据大多存储于Internet上的某个地方的服务器上，应用程序运行于云服务器和用户浏览器中。 云和网格都针对有效的水平可扩展性，避免节点的单点失效对系统的影响，都按使用付费。它们的区别是网格通常是处理一批有明确定义起点和终点的作业，而云服务是可以连续不断的。另外，云扩展了资源的类型，包括文件存储、数据库和Web服务等，也将适用性扩展到Web和企业应用。 -

Global Warming
1.Smoke is clouding our view of global warming,protecting the planet from perhaps threequarters of the greenhouse（温室）effect. That might sound like good news,but experts say that as the cover diminishes in coming decades,we are facing a dramatic increase of warming that could be two or even three times as great as official best guesses.
2.This was the dramatic conclusion reached last week at a workshop in Dahlem,Berlin,where top atmospheric scientists got together,including Nobel prize winner Paul Crutzen and Swedish scientist Bert Bolin,former chairman of the UN's Intergovernmental Panel on Climate Change(IPCC).
3. IPCC scientists have suspected for a decade that aerosols（浮质）of smoke and other partidles from burning rainforest,crop waste and fossil fuels are blocking sunlight and counteracting the warming effect of carbon dioxide（二氧化物）emissions. Until now,they reckoned that aerosols reduced greenhouse warming by perhaps a quarter,cutting increases by 0.2℃．So the 0.6℃of warming over the past century would have been 0.8℃without aerosols.
4.But the Berlin workshop concluded that the real figure is even higher—aerosols may have reduced global warming by as much as three-quarters,cutting increases by 1.8℃．If so,the good news is that aerosols have prevented the world getting almost two degrees warmer than it is now. But the bad news is that the climate system is much more sensitive to greenhouse gases than previously guessed.
5.As those gases are expected to continue accumulating in the atmosphere while aerosols stabilize or fall,that means"dramatic consequences for estimates of future climate change",the scientists agreed in a draft report from the workshop.When the cover diminishes in the coming decades,temperature_______.
A: will influence future climate change
B:was somewhat surprising
C:will rise rapidly
D:was known to US all
E:was much higher than had been expected
F:will drop dramatically答案：C解析：文章第二段指出，结论是由杰出的大气科学家得出的。“杰出的科学家” 即权威科学家。
文章第三段提到了对浮质所产生的影响进行的计算，这个计算先于第四段所提及的计算，因而，被称为“先前的”计算。
柏林研讨会得出的结论是：真正的数字比这还要高——浮质可能已经把全球气候变暖的程度减少了四分之三。因此，本段讲的是柏林研讨会的佑算。
第五段讲的是科学家们关于浮质对气候变化影响的一致性的看法。
见文章第一段。
本题翻译：“柏林讨论会的结论有点令人吃惊”。因为这个结论认为：“浮质可能已经把全球气候变暖的程度减少了四分之三。”
文章第四段指出：然而，柏林研讨会得出的结论是，真正的数字比这还要高，“比这还要高”是说比第三段推测的数字要高，也就比人们预期的要高。
文章的最后一段提到了这个问题：温室气体在大气里不断聚积对未来气候变化的预测产生惊人的后果。 -

BTrans fatty acids increase levels of “good” cholesterol.
CTrans fatty acids can be found in cookies, crackers and dairy products.
DTrans fatty acids can be found in meats and fast food.
正确答案： B解析：
该段录音指出反式脂肪酸（Trans fatty acids）会通过增加“bad” cholesterol的含量而增加心脏病的风险，因此选项B提到的““good” cholesterol”有误。

单选题It can be inferred from the second paragraph that______.Alow-altitude clouds are the main causes of global warming.
Bincrease of cloud cover can slow down the climate change.
Cglobal warming will increase cloud cover.
Dincrease of cloud cover can speed up the global warming.
正确答案： D解析：
推理判断题。根据题干提示定位至第二段。该段low-level clouds tend to dissipate as the ocean warms—which means a warmer world could well have less cloud cover，可推知B increase of cloud cover can slow down the climate change与之相符，故为正确答案；D 含义与B相反,故排除；由第二段第二句Low-altitude clouds reflect some of the sun’s radiation back into the atmosphere, cooling the earth.可知，A错；第二段最后一句It’s not yet known whether global warming will dissipate clouds or increase cloud cover，故排除C。 -

第16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’s the main idea about the first paragraph？A.Cornerstone On Demand is a provider of cloud-based learning and talent-management software
B.Placing the right type of workers together will generate 15% increase in performance
C.Smarter seating can affect company’s performance
D.A study about how a firm get additional profit答案：B解析：本题考查的是细节理解。

Ba third-world citizen adds less than a ton of CO2 yearly to the atmosphere
Cthe world climate would soon gain its balance if we stopped greenhouse-gas emissions
Dfuture prosperity of the world is dependent on cheap fossil fuels
正确答案： D解析：
根据Excerpt 4第二段中的“The average rich world resident adds about 3.2 tons of CO2 yearly to the atmosphere, more than four times the level added by each Third World citizen.”可知，第三世界国家每人每年向大气中排放的二氧化碳不足3.2吨的四分之一，也就是不到一吨的二氧化碳。故B项为正确答案。 -

推理判断题。由题干关键词定位至原文末段。由该段第二句as the earth’s surface warms, the atmosphere becomes more unstable推知，地球变暖可能改变大气构成，而这种改变又是负面的，故D为正确答案。由该段倒数第二句the trade winds weakened, which further dissipated the low clouds，可推知信风对低云层有利，故排除A；由该段第三句Those types of high-altitude clouds don’t have the same cooling effect排除B；由该段倒数第二句可知随着海洋的变暖，低层云层变少了，排除C。 -
