51. What does the example of iPhone 6s serve to show?
- A. The huge capacity of the smartphones people now use.
- B. The widespread use of smartphones all over the world.
- C. The huge impact of new technology on people's everyday life.
- D. The rapid technological progress in a very short period of time.
答案：D
答案句：Our world now moves so fast that we seldom stop to see just how far we have come in just a few years. The latest iPhone 6s, for example, has a dual-core processor and fits nicely into your pocket. By comparison, you would expect to find a technological specification like this on your standard laptop in an office anywhere in the world.
参考译文：我们的世界现在发展如此之快，以至于我们很少停下来看看我们在短短几年内取得了多大的进步。例如，最新的iPhone 6s拥有双核处理器，可以很好地放进口袋。相比之下，你会期望在世界任何地方的办公室里的标准笔记本电脑上找到这样的技术规格。
定位线索：题干“example of iPhone 6s”→答案句取自第1段“The latest iPhone 6s, for example”；文中“how far we have come in just a few years”对应选项D“rapid technological progress in a very short period of time”。
解析：本题为例证题。例子本身（iPhone 6s的处理器和便携性）不是答案依据，例子前面的观点句“Our world now moves so fast that we seldom stop to see just how far we have come in just a few years”才是关键，它强调技术进步之快，正确选项D正是对该观点的同义转述。选项A、B、C均与例子无关，属于无中生有。
52. What can we expect to see by the year 2020?
- A. Apps for the Internet of Things.
- B. The popularization of smart homes.
- C. The emergence of Millennials.
- D. Total globalization of the world.
答案：B
答案句：All researches agree that close to 25 billion devices, things and sensors will be connected by 2020 which incidentally is also the moment that Millennials (千禧一代) are expected to make up 75 percent of our overall workforce, and the fully connected home will become a reality for large numbers of people worldwide.
参考译文：所有研究都同意，到2020年，将有近250亿台设备、物品和传感器连接起来，这恰好也是千禧一代预计将占我们整体劳动力75%的时刻，并且全连接的家庭将成为全球大量人群的现实。
定位线索：题干“by the year 2020”→答案句取自第3段“by 2020”；文中“the fully connected home will become a reality”对应选项B“The popularization of smart homes”。
解析：题干问2020年可期待看到什么，答案句明确指出“the fully connected home will become a reality”，即智能家居将普及，对应选项B。选项A（物联网应用）在文中虽提及但非2020年的具体预期；选项C（千禧一代的出现）偷换概念，文中说的是千禧一代占劳动力比例；选项D无中生有。
53. What will business owners do when they become aware of the benefits of the Internet of Things?
- A. Employ fewer workers in their operations.
- B. Gain automatic control of their businesses.
- C. Invest in more smart buildings and cities.
- D. Embrace whatever new technology there is.
答案：B
答案句：However, this is just the tip of the proverbial iceberg as smart buildings and even cities increasingly become the norm as leaders and business owners begin to wake up to the massive savings that technology can deliver through connected sensors and new forms of automation coupled with intelligent energy and facilities management.
参考译文：然而，这只是众所周知的冰山一角，因为智能建筑甚至城市正日益成为常态，领导者和企业主开始意识到技术通过连接传感器和新型自动化以及智能能源和设施管理所能带来的巨大节约。
定位线索：题干“business owners”→答案句取自第4段“leaders and business owners begin to wake up to the massive savings that technology can deliver through connected sensors and new forms of automation”；文中“new forms of automation”对应选项B“Gain automatic control of their businesses”。
解析：题干问企业主意识到物联网的好处后会做什么。第四段说企业主“begin to wake up to the massive savings that technology can deliver”（意识到技术能带来巨额节省），第五段接着说这些联网设备“are offering an unprecedented level of control, efficiency, and improvements to what were once classed necessary costs when running a business”（为经营带来前所未有的掌控与效率），与选项B“获得对企业经营的自动掌控”一致。选项A“少雇人手”原文未提及；选项C“投资更多智能建筑和城市”是对“智能建筑与城市渐成常态”的推断，不是企业主的动作；选项D“什么新技术都接受”范围过大。
54. What is the most exciting challenge when we possess more and more data?
- A. How to turn it to profitable use.
- B. How to do real time data analysis.
- C. How to link the actionable systems.
- D. How to devise new ways to store it.
答案：A
答案句：The biggest and most exciting challenge of this technology is how to creatively leverage this ever-growing amount of data to deliver cost savings, improvements and tangible benefits to both businesses and citizens of these smart cities.
参考译文：这项技术最大、最令人兴奋的挑战是如何创造性地利用这些不断增长的数据，为企业和这些智慧城市的市民带来成本节约、改进和实实在在的好处。
定位线索：题干“most exciting challenge”→答案句取自第7段“biggest and most exciting challenge”；文中“leverage this ever-growing amount of data to deliver cost savings, improvements and tangible benefits”对应选项A“How to turn it to profitable use”。
解析：题干问拥有更多数据时最令人兴奋的挑战是什么，答案句明确指出是“how to creatively leverage this ever-growing amount of data to deliver cost savings, improvements and tangible benefits”，即如何利用数据获利，对应选项A。选项B（实时数据分析）在文中第6段提及但非挑战本身；选项C（连接可操作的系统）无中生有；选项D（设计新存储方式）偷换概念，文中说的是利用数据而非存储。
55. What does the author think about working from anywhere and at anytime?
- A. It is feasible with a connection to the internet.
- B. It will thrive in smart buildings, cities and homes.
- C. It is still a distant Utopian dream for ordinary workers.
- D. It will deliver tangible benefits to both boss and worker.
答案：A
答案句：The good news is that most of this technology is already invented. Let's face it, it wasn't too long ago that the idea of working from anywhere and at anytime was some form of a distant Utopian (乌托邦式的) dream, and yet now we can perform almost any office-based task from any location in the world as long as we have access to the internet.
参考译文：好消息是，这项技术大部分已经发明了。让我们面对现实吧，就在不久前，随时随地工作的想法还是某种遥远的乌托邦式的梦想，然而现在我们只要有互联网接入，就可以在世界任何地方执行几乎任何办公室任务。
定位线索：题干“working from anywhere and at anytime”→答案句取自第8段“working from anywhere and at anytime”；文中“as long as we have access to the internet”对应选项A“It is feasible with a connection to the internet”。
解析：题干问作者对随时随地工作的看法，答案句指出“we can perform almost any office-based task from any location in the world as long as we have access to the internet”，即只要有互联网就可以实现，对应选项A。选项B（在智能建筑中繁荣）无中生有；选项C（仍是乌托邦梦想）与原文“yet now we can”矛盾；选项D（给老板和工人带来好处）偷换概念，文中说的是给企业和市民带来好处。
