Manufactured by robotics company Shanghai PT Info， the brightly colored robot， which costs 5， 000yuan($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 4million.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 playa 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 Min hang 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， 000units this year. But the future is not easy for Shanghai PT Info.Earlier this year， Flying wings Intelligent Robot Technology(Shanghai) introduced a machine with sensors that will ring an alarm when an elderly person falls down.Tianjin Shangjiu Sheng yuan 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. 21.Roby Mini is the name of_______.

Passage 2 Here＇s a crazy idea：Combine bioprinting and tissue engineering to“print”animal products and tackle some of the planet＇s biggest problems.Animal farming， after all，accounts for about half of all human-caused greenhouse gases， taking place on one-third of the available， non-frozen land on Earth.All to feed people＇s appetites for 300 million tons of meat a year， Modern Meadow is a Miss our-based start up that engineers tissues to create lab-grown edible meat， in a process that eliminates many of the negative environment effects associated with traditional livestock practices. The company claims that by carefully layering mixtures of cells of different types in a specific structure， in-vitro meat production becomes feasible.It＇s set a short-term goal of printing as liver of meat around two centimeters by one centimeter， and less than half a millimeter thick， which is edible. The company explains in a submission to the United States Department of Agriculture：“The technology has several advantages in comparison to earlier attempts to engineer meat in vitro.The bio-ink particles can be reproducibly prepared with mixtures of cells of different type.Printing ensures consistent shape， while post-printing structure formation and maturation in the bioreactor facilitates conditioning.” However， it admits that the road ahead is strewn with difficulties.“The consumer acceptance of such products may not be without challenges.We expect it will first appeal to culinary early-adopter consumers and the segment of the vegetarian community that rejects meat for ethical reasons.With reduction in price， it can reach the masses with religious restrictions on meat consumption(people restricted to Hindu， Kosher， Halal diets) and finally populations with limited access to safe meat production.” Whatever the final outcome， lab-grown edible meat is no longer in the realm of science fiction.It is coming. 26.Animal farming is responsible for the occurrence of greenhouse gases. [答案]T 27.Modern Meadow is a newly-started business which aims to make profits by .producing lab-grown edible meat. [答案]F 28.The method Modern Meadow adopted to produce in-virto meat is by layering mixtures of cells of different types in a specific structure. [答案]T 29.There is no meat engineered outside living bodies before. [答案]F 30.This lab-grown meat has already widely received by the masses. [答案]F 四、写作(共计20分) 31.根据要求写作文。
