It is said to be a different product from Google Glass in terms of functionality. The company demonstrated a working prototype on September 3 at its annual Technology Innovation Conference in Beijing. It bears a similarity to Google Glass, but it has no screen. Instead, the device uses a camera to scan objects, and focuses on analyzing information around its user and beaming that to a smartphone. Baidu says the device is designed to support image search. The company's CEO Robin Li believes in five years' time, people will get used to searching by image and audio rather than text. Li has given an example of how one can take advantage of Baidu Eye, "If you are in a shopping mall and come across a woman whose skirt looks really attractive, you take a photo of her skirt using Baidu Eye, and you'll get to know where to buy one for yourself." According to Kaiser Kuo, Baidu's director of international communications, Baidu Eye can also recognize voice and gesture, "You can use voice commands, or gesture commands - like expanding to zoom, or circling an object in your field of view with your finger." Baidu is yet to announce a release date or marketing plans for Baidu Eye. Baidu is China's leading search engine company. 2.Baidulaunched a product that has more functions than Google Glasson September 3. 3.Baidu Eyecanscan objects with its small screen. 4.The company’s CEO Robin Li believes thatpeople will get used to searching by text. 5.

12. 二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。 Roby Mini is just 40 centimeters tall, has a large round screen for a head and has been designed to help senior citizens living alone. Manufactured by robotics company Shanghai PT Info, the brightly colored robot, which costs 5,000 yuan ($790), was launched on Aug 14 to help entertain and monitor elderly people. In Shanghai last year, the number of registered residents at least 60 years old was 4 million. That was nearly 30 percent of the population. By 2018, the figure is projected to rise to 5 million. With many living alone, robots such as Roby Mini can help play a crucial role in caring for the elderly. "It will change the way people interact with digital products," Hong says. Founded in May, Shanghai PT Info had already done the groundwork. In fact, the research team spent three years developing the speech recognition system before the firm was officially launched. With 360-degree wheels hidden under its body, Roby Mini can follow a person through face recognition and strike up a conversation, tell jokes or provide information. The robot also works as a computer terminal, supplying weather information, ordering groceries online and even booking taxis. Roby Mini can be connected to other gadgets as well, such as smart wristbands or magnetic devices on doors. Roby Mini can also connect an elderly owner to a doctor through its high-definition screen.Already Shanghai PT Info is talking to three community hospitals in Shanghai's Minhang district. Since the robot is linked to the Internet, it can support long-distance audio and video calls. Mass production started this month and Shanghai PT Info plans to manufacture 200,000 units this year. But the future is not easy for Shanghai PT Info. Earlier this year, Flyingwings Intelligent Robot Technology (Shanghai) introduced a machine with sensors that will ring an alarm when an elderly person falls down.Tianjin ShangjiuShengyuan Technology Group also developed a robot for seniors in 2014. Owners can turn on the lights and air-conditioning units by pressing buttons on the machine.It can also remind elderly owners to take pills, and inform them of hospital checkups and family birthdays.

24. 二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。 （课外资料） In the grass, a baby duck was hatched (孵化) out in a college biology lab with a backward left foot. At the time, it probably wouldn’t have survived, if Mike Gary didn’t recommend a proper operation to cut off that bad foot. Months after the healing process, engineers at Novacopy Company produced a 3D printed model that would be used to create a prosthetic (修复的) foot for the duck. Considering that ABS plastics were not flexible enough for this type of exercise, the Novacopy company made a three-dimensionally modeled foot made of silicone, with the hope to create a permanent prosthesis(假肢) for the duck. It took just 13 hours to produce. This 3D prosthesis demonstrated the 3D technologies can be used not only for human application, but also in foreign subjects such as animals and other medical treatments. Where was the baby duck hatched out? A. In a college biology lab. B. In a back yard. C. In Noacopy Company. 2. What was wrong with the baby duck? A. It didn’t survived. B. It was born with a backward left foot. C. Mike Gary cut off that bad foot. 3. Could ABS plastics be used to produce a 3D printed model that would be used to create a prosthetic foot for the duck? A. No, because ABS plastics were not flexible enough. B. Yes, but it could only be produced by Novacopy Company. C. Yes, because it was made of silicone. 4. How long did it take to create a permanent prosthesis for the duck? A. 10 hours. B. 13 hours. C. 30 hours. 5. What did the last sentence of this passage indicate? A. 3D technologies can be used only for human application. B. 3D technologies can be used only for foreigners. C. 3D technologies can be used to human, animals and other medical treatments.

30. 二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。 （课外选材） When computer servers operate a complex program, they can get very hot. Cooling the servers can be costly. So researchers asked what would happen if the heat created by the servers could be captured and used? Data centers of large Internet companies such as Google and Microsoft have thousands of computer servers. As these servers process information, they create large amounts of heat, so they need huge cooling systems. These systems send the heat into the air. The Dutch company Nerdalize thinks paying for electricity to operate the servers and then paying again to cool them is a waste of energy. So it developed a device called the e-Radiator. It is a computer server that also works as a heating source. Boaz Leupe is the chief executive officer of Nerdalize. He says the e-Radiator saves money because companies don't have to pay to cool their servers. "The kilowatt（千瓦）hour you are using is used twice -- once to heat the home and once to compute the client's task without the cooling overhead." He says five homeowners in the Netherlands are testing the heating device in their homes. "We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, homeowners actually get heating for free, and computer users don't have to pay for the overhead of the data center." Jan Visser is one of the participants in the year-long experiment. He says the amount of heat produced by the e-Radiator depends on the work being done by the computer server. He says it cannot be used as the primary source of heat. But he is ready to try it. He says if it provides enough warmth, he will be able to use his home's heating system less, which will save him money. Nerdalize says e-Radiators create heat temperatures of up to 55℃. It says the devices could save users up to $440 in heating costs a year. Why did researchers ask what would happen if the heat created by the servers could be captured and used? A. Because computers can get very hot. B. Computer servers is a complex program. C. Cooling computer servers costs a lot of money. 2.The computer servers in large Internet companies such as Google and Microsoft can . A. create large amounts of information B. create large quantity of heat C. manage the huge cooling systems 3. Nerdalize developed the e-Radiator because . A. e-Radiator cost less energy B. e-Radiator can cool the servers for free C. e-Radiator can create cold air for free 4.According to Jan Visser, the amount of heat produced by the e-Radiator . A. depends on the work being processed by PC B. cannot be used as the home's heating system C. cannot be used as the main source of heat 5.The best title for this passage is A. The New Way to Heat Homes B. The New Way to Cool Homes C. Hot Computers Could Be Used for Free
