Taking a picture of your tongue with a mobile phone could soon instantly tell you how healthy you are. Researchers believe the images can reveal important information about a patient’s health and even give them early warning of serious illness.
A team at the University of Missouri is developing a system that can analyze pictures using a 5,000-year-old Chinese principle, which is based on the flow and balance of positive and negative energies in the body, and uses the tongue as a key to learning about a person’s physical health, or “zheng” according to Chinese medicine.
“Within a year, our goal is to create an application for smart phones that will allow anyone to take a photo of their tongue and learn the status of their zheng,” said Dong Xu, chair of MU’s Computer Science Department in the College of Engineering and the co-author of the latest study.
The software analyzes images based on the tongue’s color and coating to distinguish between tongues showing signs of “hot” or “cold” zheng. Shades of red and yellow are associated with hot zheng, whereas a white coating on the tongue is a sign of cold zheng.
“Hot and cold zheng doesn’t refer directly to body temperature,” said Xu, “Rather, it refers to a series of symptoms associated with the state of the body as a whole.”
For the study, 263 gastritis(胃炎) patients and 48 healthy volunteers had their tongues analyzed. The gastritis patients were classified by whether they showed infection by a certain bacteria as well as the intensity of their gastritis symptoms. In addition, most of the gastritis patients had been previously classified with either hot or cold zheng. This allowed the researchers to test the accuracy of the software’s analysis.
“Our software is able to classify people based on their zheng status. And as we continue to work on the software we hope to improve its ability,” said another co-author Ye Duan, “Eventually everyone will be able to use this tool at home using webcams or smart phone applications, which will allow them to monitor their zheng and get an early warning about possible ailments.”

Has been a dream for 30 years but now the world’s first flying car is set to hit the roads this year. 
Ever since the “Back to the Future” movies lit up our screens in the 1980s, designers have dreamt of cars that could take to the sky at the push of a button(按钮). And now pilots can order their own “roadable” plane for just￡127, 000.
The plane, which has fold-out wings that span 17. 5 feet, can be up to 115 mph. Back on the land, it can also travel at “highway speeds” in car mode(模式).
Fuelling(加燃料)the 19 feet long plane couldn’t be simpler—you just drive it into a petrol station and fill it up.
A spokeswoman said, “You can keep your ‘light-sport airplane’ in your garage. But because it needs a short runway to take to the air, you will have to drive to your local airport, fly up to 460 miles, land and drive directly to your destination(目的地). You will always be ready to drive or fly. ”
The spokeswoman added, “Never let bad weather change your trip. You can simply divert(使转向)and continue on the ground until the weather clears. ”
There’s no risk to you—this is only the chance for you to be the first at your home field to unfold(展开)your wings and fly into the future.

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer．
"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.
【小题1】What can we learn from Paragraph l?
A. Driverless vehicles are now legal in the whole USA.
B. Volvo will be the first to sell driverless cars.
C. Driverless cars are pointing us' a faraway future.
D. Google's self-driving cars have covered a long distance.
【小题2】We learn that Governor of California Jerry Brown_________.
| A． helped design self-driving cars. |
| B．supports self-driving cars on roads. |
| C．considers self-driving cars science fiction. |
| D．improved the self-driving car systems. |
| A．They can help people drive more safely. |
| B．They can take the place of drivers now. |
| C．They can make cars run without fuel. |
| D．They can help cars run much faster. |
| A．They are not allowed to run on the road. |
| B．Their technical problems remain to be solved. |
| C．They are now too expensive for consumers. |

There are some things humans can go without. We can lose a kidney (肾)or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can get by without stomachs. 
One such fish is the stout longtom（尖嘴魚 ）. The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost.
The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical(热带) fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. Its teeth are not good at cutting fish into pieces, so it swallows fish whole.
Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish.
Day’s results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin（胰岛素） that can break down proteins without acid — although the approach is less efficient than using a stomach.
Because it’s a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein.
Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is “a fairly expensive organ to run”. This perhaps explains why some animals have got rid of theirs.
【小题1】What does the underlined phrase “get by” mean?
| A．Live. | B．Fight. | C．Hunt. | D．Recover. |
| A．catches smaller fish in the water |
| B．can jump so high to escape its enemies |
| C．digests the smaller fish in its body |
| D．uses acid to break down the protein |
| A．Acid | B．Trypsin. | C．The stomach. | D．Protein in its body. |
| A．the longtom often waste energy |
| B．the longtom can make acid easily |
| C．the longtom’s high-protein food helps its unique way of consuming food. |
| D．meat-eating fish have higher levels of trypsin in their bodies than plant-eating fish |

Microsoft has a problem：It desperately wants the remaining Windows XP users to upgrade to a newer version of the operating system but a good many of them still haven’t started．The latest numbers from NetMarket show that Windows XP still accounts for around 29．5％of all desktops in use even though Microsoft is due to end support for the l3-Year-old platform on April 8th．ZDNet reports that Microsoft plans to force remaining XP users to start next week by sending them notices reminding them again that it will end XP support within a month．
However, as Computerworld reports，Microsoft may have a tough time convincing some Windows XP users to upgrade because it's trying to sell them on Windows 8，the newest operating system that has angered many longtime PC users by removing the traditional Start menu and by adding the interface(界面)a special feature．Computerworld writes that many Windows users expressed anger last month when Microsoft asked them to help switch as many people as they could from Windows XP to Windows 8 partly because Microsoft hasn’t offered any sort of discount for Windows XP users making the switch．
This is particularly tiresome, these users said，because switching from XP to Windows 8 won’t just require a software upgrade but will instead likely force them to buy new machines capable(能够)of running Microsoft’s new operating system．Some users were also annoyed that Microsoft only mentioned Windows 8 and not Windows 7 as upgrade possibilities．
In the end，it looks like when Microsoft ends support for Windows XP next month there will still be a large part of the desktop PC world using the platform．Hackers who have been saving up all their best new malware(恶意软件)for the day when Windows XP support ends are about to have a field day．

Many cities have subways and underground public transportation to take locals and tourists alike rapidly around the city．However, there’s something different about riding a London subway．It may not look different, but the historical value of one of England’s most popular forms of transportation is enough to make riding the subway a must when visiting London．With a little under 100 different stations, the subway can take you almost anywhere you need to go．
Riding a London subway, a person from other countries will notice one major difference: in London, people do not look at each other．In fact, eye contact is avoided at all times．That’s not rudeness―people are just too busy to bother looking．
Busy doing what, you ask? Well, they’re certainly not using the time for a moment of quiet thinking．Nor are they reading a book．New technology has replaced quiet habits．Today the only acceptable form of book on the London underground is an e-book．
Apple must earn a fortune from London commuters（使用月票上下班者）．Since the launch of the iPhone in 2007, over 40,000―yes, that’s 40,000 “apps” have been designed．
Commuters love them because they are the perfect time-fillers．One “app”, called iShoot, is a game that features tanks．Another one, Tube Exits, tells passengers where to sit on the train to be closest to the exit of their destination．iSteam clouds the iPhone screen when you breathe into the microphone．You can then write in the “steam” on your phone screen．
For those without an iPhone, another Apple product, the iPod, may be the distraction（消遣）of choice．It’s not just teenagers who “plug in” to their music－iPods are a popular way to pass the time for all ages．
And if games, e-books and music aren’t enough to keep you occupied, then perhaps you would prefer a film? The development of palm DVD technology means many commuters watch their favorite TV shows or films on the way to work．With all these distractions, it’s amazing that people still remember to get off the train．
【小题1】People in London do not make eye contact on the subway because ______．
| A．they are going to work and have no time to communicate with each other |
| B．they love reading books and do not want to be disturbed |
| C．they feel sleepy because of getting up early |
| D．they are busy playing games, reading e-books, listening to music or watching films |
| A．computers | B．programs downloaded for the iPhone |
| C．computer companies | D．fortune from London commuters |
| A．iShoot | B．Tube Exits | C．iSteam | D．iPod |
| A．London commuters are unfriendly to strangers |
| B．Apple has earned a lot of money from selling 40,000 apps |

Dogs wag(摇摆) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back, a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs, catching their responses to a range of stimuli(刺激物) with video camems. To conduct the study, they chose 15 male dogs and 15 female ones aged between one and six years. The dogs were all family pets whose owners had allowed them to take part in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli. They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners —a positive experience— their tails wagged energetically to the right side. When they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The appearance of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Researchers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli, they tended to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were not easily noticed without the aid of video, it was thought that the findings could help people judge the mood (心情) of dogs. Computer and video systems, for example, could be used by professional dog trainers to determine the mood of dogs that they were required to approach.
【小题1】The video cameras were used to catch the dogs’ response because______.
| A．The dogs wagged their tails in different directions when they were in different moods |
| B．they enabled the dogs’ owners to know about their dogs’ habit |
| C．It was easier to catch the dogs’ response change in tail wagging |
| D．The dog were put in the wooden boxes and tested one at a time |
| A．surprise | B．worry | C．excitment | D．interest |
| A．the dogs | B．the trainers | C．the systems | D．the researchers |
| A．to train dogs for their owners |
| B．to help dogs find company |
| C．to help people judge the mood of dogs |
| D．to help people choose their pet dogs |

Boiler rooms are often dirty and steamy，but this one is clean and cool.Fox Point is a very new 47unit living building in South Bronx，one of the city’s poorest areas.Twothirds of the people living there are formerly (以前) homeless people，whose rent is paid by the government.The rest are lowincome families.The boiler room has special equipment，which produces energy for electricity and heat.It reuses heat that would otherwise be lost to the air，reducing carbon emissions(碳排放)while also cutting costs.
Fox Point is operated by Palladia，a group that specializes in providing housing and services to needy people.Palladia received support from Enterprise Community Partners (ECP)，which helps build affordable housing by providing support to housing developers.
ECP has created national standards for healthy，environmentally (环境方面) clever and affordable homes which are called the Green Communities Standards.These standards include water keeping，energy saving and the use of environmentally friendly building materials.Meeting the standards increases housing construction costs by 2%，which is rapidly paid back by lower running costs.Even the positioning of a window to get most daylight can help save energy.
Michael Bloomberg，New York’s mayor，plans to create 165,000 affordable housing units for 500,000 New Yorkers.Almost 80% of New York City’s greenhouse gas emissions come from buildings，and 40% of those are caused by housing.So he recently announced that the city’s Department of Housing and Preservation and Development (DHPD)，whose duty is to develop and keep the city’s supply of affordable housing，will require all its new projects to follow ECP’s green standards.
Similar measures have been taken by other cities，such as Cleveland and Denver，but New York’s DHPD is the largest city developer of affordable housing in the country.(2010·四川，B)
【小题1】What is the purpose of describing the boiler rooms in the first paragraph?
| A．To explain the measures the city takes to care for poor people. |
| B．To suggest that affordable housing is possible in all areas. |
| C．To show how the environmentfriendly building works. |
| D．To compare old and new boiler rooms. |
| A．Lower running costs. |
| B．Costing less in construction. |
| C．Less air to be lost in hot days. |
| D．Better prices for homeless people. |
| A．New York City is seriously polluted |
| B．people’s daily life causes many carbon emissions in New York City |
| C．a great number of people in New York City don’t have houses to live in |
| D．some other cities have developed more affordable housing than New York City |
| A．To call on people to pay more attention to housing problems. |
| B．To prove that some standards are needed for affordable housing. |
| C．To ask society to help homeless people and lowincome families. |
| D．To introduce healthy，environmentally clever and affordable housing. |

Attempts to understand the relationship between social behavior and health have their origin in history. Dubos (1969) suggested that primitive（原始的）humans were closer to the animals because they, too, relied upon their instincts to stay healthy. Yet some primitive humans recognized a cause and effect relationship between doing certain things and alleviating（减轻）symptoms of a disease or improving the condition of a wound. Since there was so much that primitive humans did not understand about the functioning of the body, magic became an integral component of the beliefs about the causes and cures of health disorders. So it is not surprising that early humans thought that illness was caused by evil spirits. Primitive medicines made from vegetables or animals were invariably used in combination with some form of ritual (礼仪) to drive harmful spirits away from a diseased body.
One of the earliest attempts in the Western world to formulate principles of health care based upon rational thought and rejection of supernatural phenomena is found in the work of the Greek physician Hippocrates. Little is known of Hippocrates who lived around 400 B.C., not even whether he actually authored the collection of books that bears his name. Nevertheless, the writings attributed to him have provided a number of principles underlying modern medical practice. One of his most famous contributions, the Hippocratic Oath, is the foundation of contemporary medical ethics (道德). Among other things, it requires a physician to swear that he or she will help the sick, keep oneself from intentional wrong-doing or harm, and keep secret all matters to keep the doctor-patient relationship.
Hippocrates also argued that medical knowledge should be derived（源自于）from an understanding of the natural sciences and the logic of cause and effect relationships. In this classic thesis, On Airs, Waters, and Places, Hippocrates pointed out that human-being is influenced by the totality of environmental factors: living habits or lifestyle, climate, geography of the land, and the quality of air and food. Interesting enough, concerns about our health and the quality of air, water, and places are still very much written in the twentieth century.
【小题1】The topic of the first paragraph is summarized in ________.
| A．the first sentence of the paragraph |
| B．the second sentence of the paragraph |
| C．the third sentence of the paragraph |
| D．the last sentence of the paragraph |
| A．Because magic was an inseparable part of their life. |
| B．Because they had little knowledge about the functioning of the body. |
| C．Because the diseases were caused by the evil spirits. |
| D．Because magic must be used in going through the rituals to drive out the evil spirits. |
| A．he was the forefather of modern medicine |
| B．experts are sure that the books bearing his name were not written by him |
| C．he had a rational mind aided by supernatural instincts |
| D．experts do not know much about him except when and where he lived |
| A．helping patients |
| B．keeping oneself from harming patients |
| C．keeping secret all matters to maintain a good relationship with the patients |
| D．obeying rules for modern medicine practice |
