The company has sold 3. 27 million iPads since they entered t he market in April. Although it’s impossible to know with certainty how many seniors(老年人)are buying them, evidence suggests that it’s a hit with seniors.“The iPad’s intuitive interface(直观界面)makes it attractive to seniors around the world, ”says Takahiro Miura, a researcher at the University of Tokyo. “The iPad is a good tool for seniors because it’s very easy to use, ”he says. “Unlike the PC, it doesn't require former knowledge. ”James Cordwell, a researcher in London, says the iPad’s popularity with sen iors is helping Apple reach beyond its traditional base of young customers. “The world’s population, especially in developed markets, is getting older. It’s probably a market where Apple has least entered, ”Cordwell says. Senior users are“a key source of growth for them in the future”.Seniors make up about 22 percent of the population in Japan. They may prove that seniors are willing to accept the iPad. Besides the customer group under 30, they spend more than any other group in the country, according to a report. Motoo Kitamura, 78, a former gas salesman, bought an iPad to help him communicate with his 2-year-old grandson and prevent him from experiencing some of the mental problems that sometimes come with getting older. “Trying new things like that is a good mental exercise, ”he says.【语篇概述】文章要紧讲述了“苹果”传统的顾客是年轻人, 然而越来越多的老年人也开始喜爱用“苹果”。

Unit 3 ComputersPeriod One Warming Up & Reading—PrereadingⅠ.阅读理解AIn the near future，we may be using our eyes to operate our smartphones and tablets，even when it comes to playing popular games like Fruit Ninja.The Gaze Group has been developing eyecontrolled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities，and are very expensive.“After a while，we figured out that probably the best way is to go for a massmarket way，” says Gaze’s Sune Alstrup Johansen，“where everybody would have this available.”Johansen and some of his colleagues have formed a new company，The Eye Tribe，which is hoping to develop the technology on a mass commercial level.The technology works when combined with the computing device toward the user’s face.After making sure of the user’s eye movements，the technology is then able to easily find where a person’s eyes are moving，and then allow the eyes to control a cursor(光标)．“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at，” reads an explanation on The Eye Tribe site.There has been a gradual change toward handsfree technology in recent y ears，particularly in the gaming world.Recently Xbox released the Kinect device，which lets users control their Xbox and play certain games using only their hands，legs and voices.But still，most of these devices have been more of a gimmick than a practical wa y to use one’s hands to control a mobile device.Johansen said a replaceable filter(滤光器) would be a cheap，convenient way for most consumers.And even as companies like The Eye Tribe work to create such a product for the average user，making the eyecontrolle d technology more accessible and lessexpensive will have similar benefits for physically disabled users.For more articles on modern science，please CLICK here.1．Which of the following is the main idea of the passage？A．An introduction of a new device.B．An introduction of smartphones.C．An introduction of eyecontrolling technology.D．An introduction of a new technology for the disabled.答案 C解析主旨大意题。
