Baidu, China's leading search engine company, has unveiled its own eyewear called Baidu Eye. 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.

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.

Passage 1(教材课文原文)

With a teeny waist, exaggerated breasts, icy-blue eyes, 21-year-old Valeria says she is the realnatural deal. A real-life Barbie, that is.

That’s what she claims anyway, but many people doubt to her claims. Whether she underwentplastic surgery or uses Photoshop remains unclear. On her blog, the model notes that she is themost famous woman on the Russian Internet because of her doll-like appeal. Hundreds of photoson her Facebook page show a wide-eyed, nearly fake-looking Valeria posing in a variety ofoutfits.

The model did not return requests for comment. If Photoshop is not a factor in getting Valeria’s look, she likely underwent a barrage of plastic surgery. The president of American Society of Plastic Surgeons （ASPS）said, plastic surgery should never be usedto transform oneself intoa favorite celebrity or, in this case, a play toy. He also warns patients to keep in mindthatplastic surgery is real surgery with real risks, just as with any operation, so the decision shouldnot be taken lightly.

 Valeria thinks thatshe is areal-life Barbie.   1

In the grass, ababyduck was hatched (孵化) out in a collegebiology lab with a backward left foot. At the time, itprobably wouldn’t have survived,ifMike Garydidn’t recommend a proper operation to cut off that bad foot.

Months after the healing process, engineers at Novacopy Company produced a 3D printedmodelthat would be used to create a prosthetic(修复的)foot forthe duck. Considering that ABS plastics werenot 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 permanentprosthesis(假肢)for the duck.

It took just 13 hours to produce. This 3D prosthesis demonstrated the 3Dtechnologies canbe used not only for human application, but also in foreign subjects such as animals and other medical treatments.

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   1    

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    2    .

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    3    .

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    4    .

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

 Wide World of Robots

Engineers who build and program robots have fascinating jobs. These researchers tinker (修补) with machines in the lab and write computer software to control these devices. "They're the best toys out there," says Howle Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist, a person who designs, builds or programs robots.

When Choset was a kid, he was interested in anything that moved--cars, trains, animals. He put motors on Tinkertoy cars to make them move. Later, in high school, he built mobile robots similar to small cars.

Hoping to continue working on robots, he studied computer science in college. But when he got to graduate school at the Califomia Institute of Technology in Pasadena, Choset's labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist (扭曲 ) in many directions and travel over a lot of different types of terrain (地形) . "Snakes are far more interesting than the cars," Choset concluded.

After he started working at Carnegie Mellon, Choset and his colleagues there bagan developing their own snake robots. Choset's team programmed robots to perform the same movements as real snakes, such as sliding and inching forward. The robots also moved in ways that snakes usually don't, such as rolling.

Choset's snake robots could crawl (爬行) through the grass, swim in a pond and even climb a flagpole.

But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries, the doctor has to open a patient's chest, cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake

Choset teamed up with Marco Zenati, a heart surgeon now at Harvard Medical School, to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs.

A company called Medrobotics in Boston is now adapting the technology to surgeries on people.

Even after 15 years of working with his team's creations, "I still don't get bored of watching the motion of my robots," Choset says.

 Choset began to build robots in high school.   1    

2. Snake robots could move in only four directions.   2    

3. Choset didn't begin developing his own snake robots until he started working at Carnegie Mellon.   3    

4. Zenati tested the robot on people after using it in pigs.   4    

5. The robotic technology for surgeries on people has brought a handsome profit to Medrobotics.   5

教材课文原文

 The Company Leading the Future of Farming

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 Missouri-based startup 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 a sliver 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.

 Animal farming is responsible for the occurrence of greenhouse gases.   1    

2. Modern Meadow is a newly-started business which aims to make profits by producing lab-grown edible meat.   2    

3. The method Modern Meadow adopted to produce in-virto meat is by layering mixtures of cells of different types in a specific structure.   3    

4. There is no meat engineered outside living bodies before.   4    

5. This lab-grown meat has already widely received by the masses.   5
