The hospital food was excellent， so I was able to choose from a large and varied Menu. In my private room， there was cable T. V.， a fridge， a phone， and impressive views of Bangkok(曼谷). My Translator was able to communicate with me， and the plastic surgeons arranged the whole operation without me lifting a finger. The operation cost me a third of the price of the U. K. With the low cost of the air tickets and a holiday， it worked out at about half UK＇s price， because the cost in Thailand is so cheap. Combining a plastic surgery with a holiday in an amazing place is an unforgettable experience.

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 real natural deal. A real-life Barbie， that is. That’s what she claims anyway， but many people doubt to her claims. Whether she underwent plastic surgery or uses Photoshop remains unclear. On her blog， the model notes that she is the most famous woman on the Russian Internet because of her doll-like appeal. Hundreds of photos on her Facebook page show a wide-eyed， nearly fake-looking Valeria posing in a variety of outfits. 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 used to transform oneself into a favorite celebrity or， in this case， a play toy. He also warns patients to keep in mind that plastic surgery is real surgery with real risks， just as with any operation， so the decision should not be taken lightly. 1. Valeria thinks that she is a real-life Barbie. [答案F] 2. Valeria used to accept plastic surgery. [答案F] 3. Valeria writes that she is the most famous woman on the Russian Internet because she posts a lot of pictures on her blog. [答案F] 4.

(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. 1. Where was the baby duck hatched out？[答案A] A. In a college biology lab. B. In a back yard. C. In Noacopy Company. 2. What was wrong with the baby duck？[答案B] 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？[答案A] 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？[答案B] A. 10 hours. B. 13 hours.

PASSAGE 1 (教材课文原文) The printer did not always manage to spread the plastic evenly， making some of the ribs of the honeycomb structure of the block uneven， reported ARN (Australian Radio Network) to the surprise of no one who has used a 3D printer. But the architects remain optimistic. The first few printed blocks are meant to be test pieces as they improve the process. It takes about a week to print a 3-meter high block right now. The project＇s leaders hope to eventually get that down to two hours and finish the first of 12 rooms in a year， and the entire house in less than 3 years. Ultimately， 3D Print Canal House is an architectural research project， one that is very much being conducted in the public eye：you can actually buy tickets to visit the construction site for 2.50 Euros. The top floors will become more ornate， for example， as newer techniques are incorporated. They＇ll explore the possibilities of 3D printing， like the honeycomb walls or an entire room recycled， redesigned， and built anew. Nobody＇s going to move into a 3D printed house soon， but， if anyone ever does， something might be learned from this experiment by the canal. 1.

(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. 1.Why did researchers ask what would happen if the heat created by the servers could be captured and used？[答案C] 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[答案B]. 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[答案B]. 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[答案C]. 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[答案A] A. The New Way to Heat Homes B. The New Way to Cool Homes C. Hot Computers Could Be Used for Free 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 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. 1. Choset began to build robots in high school. [答案T] 2. Snake robots could move in only four directions. [答案F] 3. Choset didn＇t begin developing his own snake robots until he started working at Carnegie Mellon. [答案T] 4. Zenati tested the robot on people after using it in pigs. [答案F] 5. The robotic technology for surgeries on people has brought a handsome profit to Medrobotics. [答案F] 二、阅读理解：阅读下面的对话，选择合适的内容将对话补充完整。

(课外选材) According to experts， the advantage of modified food is that it helps in preventing the occurrence of allergies and also has a long shelf life. However， a major portion of the population is against the consumption of genetically modified food and is concerned about its disadvantages. If you are also confused about the consumption of genetically modified food， read through the pros and cons given below and decide for yourself. ADVANTAGES OF GENETICALLY MODIFIED FOODS ●One of the most prominent advantages of genetically modified food is that it helps in controlling the occurrence of certain diseases. Certain foods cause allergy to people. Their genetic modification alters the DNA system of these foods， thereby making them non-allergic. ●Another major advantage of such type of foods is that they grow faster than their traditionally grown counterparts. As a result， there is greater productivity and more food. ●A person need not bother about any additional costs， such as buying chemicals and pesticides， when it comes to genetically engineered food. The food is naturally pest-resistant. ●Farming these foods can be a great way to fight world hunger. Since these crops grow faster or more effectively， increased production would help countries wherein crops may not normally prosper because of less than desirable environmental conditions. ●The increased shelf life of these food products helps in reducing the quantity of rotten food. DISADVANTAGES OF GENETICALLY MODIFIED FOODS ●The biggest disadvantage of genetically modified food is that they have harmful effects on the human body. The consumption of these genetically engineered foods can lead to development of diseases that are immune to antibiotics. ●Chances of developing cancer are high in people who regularly consume engineered food. ●Since it is an unnatural way of producing foods， there is an increased health hazard such as allergens， transfer of antibiotic resistance markers and unknown effects. ●Since the production of engineered food involves infusing animal genes in the crops and tampering with nature， it might not be good for consumption in the long run. 1. How does genetically modified food control the occurrence of certain diseases？[答案C] A. By cross-pollinating. B. By conventional crossbreeding. C. By altering the DNA system of these foods. 2. Do farmers need to buy any chemicals and pesticides if they plant genetically modified food？[答案B] A. Yes， they need to. Because the food is not resist to pests. B. No， they don’t need to. Because the food is naturally pest-resistant. C. No， they don’t need to. Because the chemicals and pesticides are provided by the government. 3. Which statement is not the advantage of genetically modified food？[答案A] A. It may have harmful effects on human body. B. Genetically modified food grows faster than their traditionally grown counterparts. C. Farming genetically modified food can help fight world hunger. 4. What would happen to a person if he regularly consume genetically modified food？[答案C] A. He would get cold. B. He would lose some weight. C. He would have cancer. 5. Which title is the best for this passage？[答案C] A. Can genetically modified foods combat world hunger？ B. Genetically modified mood：our answer is no C. Genetically modified foods：pros and cons 二、阅读理解：阅读下面的短文，根据文章内容进行判断，正确写T错误写F。

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. 1. Animal farming is responsible for the occurrence of greenhouse gases. [答案T] 2. Modern Meadow is a newly-started business which aims to make profits by producing lab-grown edible meat. [答案F] 3. 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] 4. There is no meat engineered outside living bodies before. [答案F] 5. This lab-grown meat has already widely received by the masses.
