问题    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.
   It’s no wonder that new applications for the Internet of Things are moving ahead fast when almost every new device we buy has a plug on the end of it or a wireless connection to the internet. Soon, our current smartphone lifestyle will expand to create our own smart home lifestyle too.
   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.
   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.
   Online security cameras, intelligent lighting and a wealth of sensors that control both temperature and air quality are offering an unprecedented level of control, efficiency, and improvements to what were once classed necessary costs when running a business or managing a large building.
   We can expect that the ever-growing list of devices, systems and environments remain connected, always online and talking to each other. The big benefit will not only be in the housing of this enormous and rapidly growing amount of data, but will also be in the ability to run real time data analytics to extract actionable and ongoing knowledge.
   The biggest and most exciting challenge of this technology is how to creatively leverage this evergrowing amount of data to deliver cost savings, improvements and tangible benefits to both businesses and citizens of these smart cities.
   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.
   It’s time to wake up to the fact that making smart buildings, cities and homes will dramatically improve our quality of life in the years ahead.
What does the example of iPhone 6s serve to show?
选项 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
解析 推理判断题。通常来讲，例子支撑其所在位置前后的观点。作者在第一段第一句提到，如今，我们的世界进步得如此之快，以至于我们很少停下来看看我们在短短的几年内究竟走了多远。该句表明短时间之内世界发展迅速，但并未具体说明是在哪一方面。随后作者在第二句中以iPhone 6s为例，阐述了最新款苹果手机的先进，说明技术在迅速发展，故答案为D)。
