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.

The company claims that by carefully layering mixtures of cells of different types in a specific structure， in-vitro meat production becomes feasible.Its 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、寫作(共計20分) 31.根據(jù)要求寫作文。Please write a product description according to the given information.(根據(jù)以下信息寫一份英文產(chǎn)品說明) 產(chǎn)品名稱：掃地機器人 型號：Roomba 790 基本功能：高度智能和自動化的掃地機器人。通過多個感應(yīng)器和多種行動模式清潔房間。特點：(1)高能效。160分鐘持續(xù)工作時間，是同類產(chǎn)品的2倍。(2)超薄輕巧。重2.5千克，高度8.9厘米。(3)獨特門檻攀爬模式。同類產(chǎn)品最多能越過10厘米高的障礙，本產(chǎn)品能越過20厘米高的障礙。Words for reference： 掃地機器人Robotic Cleaner 自動地automatically 多個的multiple 門檻threshold 能量energy efficiency 工作時間operating time 參考答案： Robotic Cleaner Roomba 790 Robotic Cleaner Room ba790saves your time and effort.It will clean your home automatically and intelligently with multiple sensors and dozens of behaviors.
