Computers are very important to modern life. Many people think that in the future computers will be used a lot in everyday's life. It is thought that we won't have to go shopping because we will be able to get most things which are sold in shops on the Internet. There will be fewer books because we will be able to get all texts from computers. The Internet will be used to play games, see films and buy food. Most telephone calls will be made by computers, too. Some people are glad about these new ways of shopping and communicating . Others do not think that computers will replace our old ways. Let's take books for example. Some people think that one day we won't read books made of paper. Instead, we will buy and read books using computers. We will read texts on small pocket computers. The computers will keep many different books in them at the same time. We won't need to turn lots of pages and paper will be saved. Computerized books will be used more and more. Is Internet shopping such a pleasure as going to the shop? Many people say it is not. It is a pleasure to go into shops and look at things you want to buy. It is also unlikely that many people will want to read large texts on our computers. Because paper books will perhaps be more friendly. Maybe computers won't change these two habits . Which reason for using computerized books is NOT said in the passage?
[ "We won't need any paper.", "Computers can keep many different books in them.", "We won't have lots of pages.", "Computerized books won't be very expensive." ]

Tim Berners-Lee is the man who wrote the software program that led to the foundation of the World Wide Web. Britain played an important part in developing the first generation of computers. The parents of Tim Berners-Lee both worked on one of the earliest commercial computers and talked about their work at home. As a child he would build models of computers from packing material. After graduating from Oxford University he went on to the real thing. In the 1980s, scientists were already communicating using a primitive version of e-mail. While working at a laboratory in Switzerland, Tim Berners-Lee wrote a program, which let him store these messages. This gave him another idea: write a program that will let academics from across the world share information on a single place. In 1990 he wrote the HTTP and HTML programs which form the basis of the World Wide Web. The next year his programs were placed on to the Internet. Everyone was welcome to use them and improve them if they could. Programmers used this codes to work with different operating systems. New things like web browsers and search engines were developed. Between 1991 and 1994 the number of web pages rose from 10 to 100,000. In 1994 Tim Berners-Lee formed the newly formed World Wide Web consortium , or W3C. More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone can share equally on the web. "The Web can help people to understand the way that others live and love. It helps us understand the humanity of people." he says. Tim Berners-Lee decided to write a program that would let academics from across the world share information on a single place when .

Money, jewels and important documents are not the only valuable placed in banks these days. Some mothers store their breast milk in banks. There're ten breast banks set up across the United States, where mothers can donate their extra milk for other women's babies. Experts say breast milk is the best food for babies. The World Health Organization says it is the only food babies should get during the first six months of life, in most cases. Breast milk is especially important for babies born too early. Sometimes these premature babies must stay in the hospital for many weeks. James Cameron is a doctor who treats newborns at Lutheran Children's Hospital in Fort Wayne, Indiana. He says breast milk is almost like medicine. Doctor James Cameron said, "The fact is that there are so many different proteins and specialized sugars in the breast milk that the mom's able to make that help provide immunity. It's very important for the health of the newborn." There are several reasons some mothers may not be able to breastfeed. Some are not able to produce enough milk. Others might be taking medicines or have medical problems that prevent the process. Lucy Baur lives near Fort Wayne. She fed her milk to both her children and always had more milk than they needed. She wanted to donate to the Indiana Mothers Milk Bank in Indianapolis. But freezing and shipping milk can be costly. Then, a donor station opened near her home. Milk donations in the United States work like this: Donors must be willing to provide almost three liters of breast milk. They freeze the milk and take it to the station. There, employees warm the milk and mix it with other mothers' milk. Then, the milk is heated to kill bacteria. After that, the technicians test samples of all the milk to make sure it is safe and healthful. The milk is re-frozen and sent to the main milk bank. The milk bank transports the milk to hospitals to feed premature or sick babies. Donors are tested for diseases before any milk is accepted. _ are not permitted to smoke tobacco, use illegal drugs or drink too much alcohol. The purpose of setting up breast milk banks is to _ .

Facebook is now used by 30 million people in the UK,about half the population. Joanna Shields,vice president of Facebook Europe,made the announcement this morning at a media conference in London. She said: "We can announce today that we have reached 30 million in the UK,which we are really excited about." Globally,Facebook has more than 500 million registered users,a milestone it hit last summer.Last July,it also revealed that it had 26 million registered UK users.In the last eight months,it has attracted four million extra UK users,bringing the UK total to 30 million,while in January 2009,Facebook had only 150 million registered users. Last year,Zuckerberg,Facebook's founder,said it was "almost a guarantee" that the site would hit one billion users.He explained: "If we succeed in innovating,there is a good chance of bringing this to a billion people...it will be interesting to see how it comes true." One third of women aged 18 to 34 check Facebook when they first wake up,before even going to the toilet,according to research.Twenty-one per cent of women aged between 18 to 34 check Facebook in the middle of the night,while 42 per cent of the same group think it is fine to post drunken photos of themselves onto the social network,a study by Oxygen Media found. Shields was speaking this morning at the Financial Times Digital Media and Broadcasting Conference about the power Facebook's referrals can bring to media sites,such as newspapers and TV services. She explained that the average Facebook user has 130 friends who they share links to media sites with on a regular basis."Media companies which take advantage of that are really seeing the benefits",Shields said. Shields refused to say whether Facebook would develop its own mobile phone operating system and also said it was "silly" that Google had recently disabled the feature which allowed Google users to sync their contacts with Facebook friends.

According to scientists' research, the month in which babies are born could affect them in some ways. Babies born in spring get sick easily. Children born under Aquarius may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn Scientists believe many of the differences can be explained by the mother's exposure to sunlight in pregnancy . Sunlight helps lead to the production of Vitamin D in the body. The lack of this in the first months of life may have a bad effect on mental and physical health. Vitamin D, called the "sunshine vitamin", is known to help regulate thousands of genes during development, according to a study of more than two million people. So Vitamin D has a good effect on health This study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the USA showed that people born in autumn lived about 160 days longer than those born in spring. Professor Russell Foster, an Oxford University neuroscientist on seasonal biology, said the conclusions were surprising and interesting. He added, "These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth." According to the passage, _ can help people get Vitamin D.

Monkeys prefer heavy metal to classical music, according to researchers at the University of Wisconsin whose findings are published this week in Biology Letters. Scientists played a selection of music to a group of South American cotton-top monkeys but the only sound that got a reaction were from the heavy metal band Metallica. They were seemingly disinterested in Led Zeppelin, Miles Davis and Bach, but after the beautiful sound of Master of Puppets by Metallica was played the monkeys calmed down. "Monkeys interpret rising and falling sounds differently than humans. Oddly, their only response to several samples of human music was a calming response to the heavy-metal band Metallica," said Professor Charles Snowdon, from the University of Wisconsin-Madison. Rather than making them excited or aggressive, the heavy metal tracks had a comforting effect. Dr Snowdon, who teamed up with National Symphony Orchestra musican David Teie, also played the monkeys music composed specifically for them. Although they enjoyed Metallica, they were much more interested in these pieces. A melody based on the short calls of scared monkeys led to anxiety levels rapidly growing, researchers found, while one based on long calls the creatures make when they are happy had a calming effect. Frans B.M. de Waal, a professor of psychology at Emory University who studies animals, said the findings appear to say more about how monkeys respond to the sounds they make than they do about music or the evolution of music. Dr Snowdon no longer has a monkey colony to use in his research, but he said his co-author David Teie is exploring the concept of music for cats. "If we understand how we can affect their emotional states through using musical sound and aspects of our speech, maybe those of us living with companion animals can have a better relationship with them, too," Snowdon said. According to the passage, the monkeys are most interested in the music _ .

Room doctors and medical groups around the world last weekend reacted with strong opposition to the news that an Italian specialist is _ cloning the first human baby. Dr. Severino Antinori, who is head of a hospital in Rome, has been referred to in an Arab newspaper claiming that one of his parents is eight weeks pregnant with a cloned baby. Antinori refused to comment on the reports, but in March 2001 he said he hoped to produce a cloned embryo for implantation with two years. So far seven different kinds of animals have already successfully been cloned, including sheep, cats and most recently rabbits. Doctors showed their doubt and were strongly opposed although they admitted that human cloning would finally come true unless there was a worldwide ban on the practice. Professor Rudolf Jaenisch of the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology said, "I find it astonishing that people do this where the result can be foretold that it will not be a normal baby. It is using humans as guinea pigs . It makes people feel sick." But Ronald Green, director of the Ethics Institute at Darmouth College in the USA, said it is unlikely that an eight-week-old pregnancy would lead to a birth. So far all cloned animals have suffered from some different serious disorders, many of them dying soon after their birth. Doctors are opposed to human cloning because they are worried about the welfare of the cloned child if there is one. "There are no benefits of cloned human beings, just harm," said Dr. Michael Wilks of the U.K. What would be the best title for the passage?

Of all the animals in the animal kingdom, which one (aside from man) is the cleverest? There are several ways of measuring the intelligence of animals. In one test a scientist sets three same cans on a table. While the animal watches, he puts food under one of the cans. Then he leads the animal away. Some time later, he brings it back to see if it remembers which can has the food. No smelling is allowed; the animal must go directly to the correct can or it fails. This is called a delayed-response test. The idea is to find out how long an animal's memory can keep information. The scientists would try showing the cans to the animal one hour later, or two hours later, or even a full day later. They discovered that chimpanzees and elephants have the best memory, and were able to remember the correct can for at least twenty hours. No other animal is close. Dogs came next, but they only remember for nine hours. To settle the matter, the scientists designed a huge maze and ran the chimps and elephants through it. The maze was very difficult, with many blind paths and dead ends. It took the chimps ten minutes to find their way out. The elephants needed half an hour. Even allowing for the elephants' slower rate of speed, the test shows that chimpanzees are the cleverest animals. From this and other tests, the scientists drew the following conclusion: an animal's intelligence depends on the size of its brain in proportion to the size of its body. The elephant's brain weighs ten pounds. But this is only 1/600th of its 6,000 pounds body. A chimp's brain weighs about one pound, or 1/120th of its total body weight. So in proportion to its body size, the chimp has four times as much brain as the elephant----more brain for less body. The chimp is the champ! Which is the best title?

The Food and Drug Administration (FDA) is expected to rule soon that milk from cloned animals and meat from their offspring are safe to eat. The agricultural industry has observed a self-acting stop on using the products of clones, but it has recently become clear that a few offspring of cloned pigs and cows are already flowing into the food supply. Many in agriculture believe such genetic copies are the next logical step in improving the nation's livestock . Many Americans are likely to be against the idea of serving clones' milk to their children or putting meat from the offspring of clones into the kitchens. When they were asked earlier this year in a survey by the International Food Information Council whether they would willingly buy meat, milk and eggs that come from clones if the FDA declared them to be safe, 63 percent of consumers said no. Yet scientific evidence suggests there is little cause for alarm, at least on food-safety grounds. Studies have shown that meat and milk from clones are not different from that from normal animals, although work is not complete and researchers say that clones do suffer slight genetic abnormalities . While milk from clones might reach the shelves, _ They'd be used as breeding stock , so the real question is whether their produced offspring would be safe.

Running like the wind, roaring like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China. This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund. The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950s, there were over 4,000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species. Sixty-six of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves. "Breeding has damaged the quality of the species," said Pei Enle, deputy director of the Shanghai Zoo. To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts and can hunt wild animals by themselves at the African base. "South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in," said Lu Jun, office director of the National Wildlife Research and Development Centre. "We tried in Fujian Province, but it was not successful as there was not a complete eco-chain and there was a lack of space." The tigers should return to China in 2009 when the reservations in Fujian are ready. What is the purpose of sending young tigers to South Africa?

A California family drives a car that could help protect the environment. When Jon and Sandy go to the store or to their daughters' soccer games, they drive in high-tech style. They drive a $1 million, fuel-cell-powered car. It may be the world's most expensive car and one of the most environmentally friendly cars. The FCX is the first fuel-cell-powered car to be used by a family anywhere in the world. The FCX uses hydrogen and oxygen for fuel. Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline. And then what is fuel cell technology? Fuel cell technology works by changing the chemicals hydrogen and oxygen into water. This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. "The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment," scientists say. Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use. Another earth-friendly car is already on the market. Hybrid cars use both gasoline and an electric motor. They are becoming more popular with customers because they cut pollution and improve fuel efficiency. Hybrid cars are popular because _ .

Some people can stay up all night and still get work done the next day. I'm not one of them. After a night without enough sleep, I feel bad-tempered. I have trouble remembering things. And all I want to do is go to bed. How do you feel after you've stayed up late to finish schoolwork or the day after an overnight party? Scientists now say that your answers to these questions may depend on your genes. New research suggests that a gene called "period 3" influences how well you function without sleep. The "period 3" gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you. Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of "period 3". Study participants had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed on a screen and how well they could remember lists of numbers. Results showed that the people with the short form of "period 3" performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning. After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests (those with the short form of "period 3") took about 18 minutes to nod off. While people with the long "period 3" gene fell asleep in just 8 minutes. They also spent more time on deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form. I think I must have the long form of "period 3". What about you? The purpose of this passage might be _

When you think about math, you probably don't think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals. People who solve crimes look for patterns that might reveal the identity of the criminal. It's long been believed, for example, that criminals will break the law closer to where they live, simply because it's easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it. But Mike O'Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal's home base by combining these patterns with a city's layout and historical crime records. The records of past crimes contain geographical information and can reveal easy targets -- that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections are. O'Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal's patterns change with age. It's been shown, for example, that the younger the criminal, the closer to home the crime. Other computer programmers have worked on similar software, but O'Leary's uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country. The program is just one way to use math to fight crime.

Contrary to people's previous knowledge, it's food shortage not dietary preference that motivates birds to migrate thousands of miles back and forth between breeding and nonbreeding areas each year, a new research shows. "It's not whether you eat insects,fruits or candy bars or where you eat them that counts,but how reliable that daytoday food source is," said the study leader W.Alice Boyle of the University of Arizona. To figure out the underlying pressure that drives some birds to leave home for the season,Boyle examined 379 related species of New World flycatchers and compared their sizes,food types, habitats, migratory behaviors and whether or not they fed in flocks. To compare the birds,the researchers constructed a "supertree" showing the exact evolutionary relationships among different species. A computer analysis then determined whether a particular species was migratory because it ran in the "family" or whether something in the bird's environment was forcing it to leave each season.Boyle and her colleagues found that food shortage was the number one issue that predicted a species' migratory behavior. "Food availability is the underlying pressure, not diet and habitat," Boyle said. An alternative strategy that the birds use to handle food shortage is to hunt in flocks, since a group is more likely to find a new source of food than an individual. "If you suffer from food shortage, you have two options," Boyle said."You can either hunt with other birds or you can migrate." The passage implies that _ .

Su Hua is studying at Cambridge, UK. She has bought a bicycle and is worried about security. Her friend, Kate, found this article and sent it to her. www.zxxk.com Introduction A lot of crime is against bicycles. About 150,000 bicycles are stolen every year and most are never found. You can prevent this happening by following a few careful steps. Basic Security Do not leave your bicycle in out-of-the-way places. Always lock your bicycle when you leave. Secure it to lampposts or trees. Take off smaller parts and take them with you, for example lights and saddles . Locks Get a good lock. There are many different types in the shop. Buy one that has been tested against attack. Ask for a recommendation from a bike shop. Marking Security marking your bike can act as a deterrent to a thief. It can also help the police find your bicycle. It should be clearly written and include your postcode and your house or flat number. This will provide a simple way to identify your bicycle. Registration There are a number of companies who will mark your bicycle for you. They will then put your registration number and personal details on their computer database. Then if your bicycle is found it will be easy to contact you. Finally Keep a record of the bicycle yourself: its make, model and registration number. You can even take a photograph of it, this will prove the bicycle belongs to you. Which of the following statements is true?
[ "More than 150,000 bicycles are stolen every year.", "Leave your bicycle in out-of-the-way places.", "Taking a photograph of your bike will help prove the bicycle belongs to you.", "Always lock your bicycle even if you don't leave." ]

Twenty-three-year old Rio Safiyanto sells face masks, or coverings, for about 30 cents each in central Jakarta, Indonesia. He makes enough money to buy a cell phone that permits him to visit websites. He says every average person has a cellphone. He likes having one because he can talk to his family when he is away from home. And, he is especially pleased that he can use it to listen to music. It is known as a feature phone . That is because it is cheaper and cannot perform as many actions as more advanced phones like the Apple iPhone. These devices make up the majority of cell phones sold around the world. They have proven more successful in places like Indonesia, where some smartphones cost 700 dollars or more. Although many lower-income users are new to smartphones, they are quickly learning to use the technology. Cell manufacturer Nokia offers a service called Life Tools. For a small monthly payment, the company sends text messages to farmers. The messages tell of weather conditions, crop prices, agricultural news and give other advice. Local businessman Aldi Haryopratomo has developed a way for small store owners to sell things like prepaid cellphone minutes and life insurance through text messages. Ruma is the company that developed the technology. The company is working on a system that will _ people about jobs in their area. At a recent digital technology show in Jakarta, banks offered no-interest financing for credit card purchases. Marina Luthfiani manages a mobile shop in the area. She said almost everyone can buy a smartphone because of competitive financing and credit choices. She says Indonesians like to buy the latest devices.

Dolphins are not fish. They are mammals .They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain is as big as men's and they live a long life at least 20 or 30 years. Like some animals, dolphins use sounds to help them find their way around. They also use these sounds to talk to each other and to help them find food. They do not use their ears to receive sounds,but use the jaw--the lower part of the mouth. It is strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand,there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903 ,Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat with the name of The Penguin shot and hurt Jack. Luckily the dolphin didn't die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the boat of the Penguin. Today, some people still kill dolphins, but many countries in the world now protect them. In these places, people are not allowed to kill them.

Jerry Morris died on 28 October 2009. He was 99 years old. You have probably never heard of him. He was a professor of public health. More than 50 years ago he produced one of the most famous epidemiological papers of the 20th century. His study showed that bus conductors were much less likely to die of heart disease than bus drivers. Why? Because the conductors spent their working day walking. It seems obvious now but in the middle of the last century doctors were puzzled by the rising numbers of people who got heart diseases. Jerry Morris found one of the main causes: a sedentary lifestyle. He started exercising for a few minutes each day and lived until his 100th year. If you wish to protect your heart, you have to do more than wander in the garden. The exercise needs to be reasonable. Jogging is not for everyone and a round trip to the gym takes a couple of hours, plus the monthly membership fee is only good value if you visit regularly. The answer is simple: walk. A half-hour purposeful walk five times a week will lower your risk of heart disease, diabetes and strokes. Older people sometimes feel they have left it too late. But it is never too late to start and there are no upper age limits. Start gently. Take your time: a 15-minute flat walk in the nearest park, four or five times a week. Within a month or so, you are already beginning to protect your heart. Build the walks up. When you can comfortably walk for half an hour in the park, go further: try following rivers and canals. Regular walkers have their own natural gymnasium. There is no membership fee, just some of the finest scenery in the world. Great Britain is the walker's gym. When you have followed the rivers and canals, and are enjoying walking for a couple of hours, head for the coast. Once again, build it up slowly. When you are comfortable with long coastal walks, you can think of our national parks. We can learn from the passage that _ .

If you want to keep healthy, you should have good habits. What is a habit? It is something we do very often. We don't even think when we do it. It has become a part of our lives. "Early to bed, early to rise makes a man healthy, wealthy and wise." This is an old English saying. Do you know what it means? It means that we must go to bed early at night and get up early in the morning. If we do, we shall be healthy, rich and clever. Is this true? Perhaps it is. We know the body must have enough sleep. Boys and girls need eight or nine hours' sleep every day. Some people go to bed late at night and get up late in the morning. This is a very bad habit. Then you will not think or do your work well. Of course, you can't be healthy, wealthy or wise. When we get up early in the morning, we can go out and do morning exercises. Exercise means doing things with the body. Walking, running jumping, swimming, and playing ball games are all exercise. If we don't exercise, our body will become weak. Exercise helps the blood to move around inside our body. Blood takes food to all parts of our body. Our body also needs air to breathe. Without air, we will die. We must have lots of clean fresh air if we want to be healthy.

Many people are aware of the beauty of a solar eclipse , but are surprised to learn that lunar eclipses are often just as impressive. While total solar eclipse lasts only for a few minutes and can be seen only in a small area of a few kilometers, total lunar eclipse can last for several hours and can be seen over much of the planet. In fact, the beauty and _ of lunar eclipses make them a favorite of both amateur and professional photographers. Lunar eclipses generally occur two or three times a year, and are possible only when the Moon is full. When we see the Moon, we are actually seeing sunlight reflected off the surface of the Moon When the Earth is positioned in between the Moon and the Sun, however, the Earth's shadow falls on the Moon, and a lunar eclipse occurs. The type of lunar eclipse - total, partial, or penumbral - that occurs depends both on how much of the Moon passes through the Earth's shadow and through which part of the shadow it passes. A penumbral eclipse occurs when the Moon passes through the Earth's outer shadow. This type of eclipse is brief and frequently goes unobserved by all but astronomers. By contrast, total and partial eclipses occur when all or part, respectively, of the Moon passes through the umbra shadow of the Earth. These eclipses are quite easy to see and are widely observed. Unlike solar eclipses, lunar eclipses are safe to watch. Solar radiation that occurs during an eclipse of the Sun can cause a form of burns of one's eyes known as eclipse blindness. In fact, the only way to safely view a solar eclipse is by using specially designed equipment. However, since the Moon's light is reflected sunlight, it is completely safe to watch a lunar eclipse without any special equipment, although a pair of binoculars can certainly help the viewer appreciate the beauty of this phenomenon The passage implies that penumbral eclipses are _ .

It is reported by Chinese Xinhua News that students waste more food than the national average. So the campaign on school food waste is getting popular across the country. The move is part of a national campaign started by students at different schools. At East China University of Science, students who finish their food in the school dining hall get a special card when they return their plates after meals. Students can collect cards and exchange them for small gifts, such as books, schoolbags, magazines and umbrellas. "It's been such a surprise," said Liang Zhaoyun, 19, a student in Shanghai. "It has given us one more motivation to eat up our food." "The purpose of the campaign is not only to encourage students to finish their food. We hope it can also teach students to choose a more environment-friendly and healthy lifestyle," said Tao Siliang from University of Traditional Chinese Medicine. Other schools also pay attention to the quantity of food. At Nanjing No.9 Middle School, rice is divided into three different-sized bowls that students can choose from according to their own need. "It's great because I can try different dishes at half price and don't waste so much food," said Fan Peng, 15, a student from this middle school. What if you really can't finish all your food? At Changchun Normal College, they provide a take-away service. "If you can't finish all your food, you can get a box to take the left food home. Even if you feed the cat, it's not wasted," said Zhou Zeyong, a student who learns Chinese education. "I'm happy that we've cut down waste since joining the school 'eat-up' meeting. But some food is poorly cooked, meaning that students are not willing to finish it all. Some schools have taken note of this. So if we hope students try to waste less food, we should also improve the service and keep an eye on the meal quality on weekdays at school. If not, you can't complain students for throwing away much food," said Wang Guangji, the head-teacher of Beijing No. 29 Middle School. Why did we start the campaign on food waste at schools?

A villa designed to resist earthquakes with "self-healing" cracks in its walls, thanks to nanotechnology applications with self-healing polymers , is to be built on a Greek mountainside. The villa's walls will include special particles that turn into a liquid when squeezed under pressure, flow into cracks, and then harden to form a solid material. The NanoManufacturing Institute (NMI), based in Leeds University, will play a key role in an EU project to construct the home by December 2010. The project, called "Intelligent Safe and Secure Buildings" (ISSB) is funded under the EU's Sixth Framework program. This potentially life-saving scheme is led by German building manufacturer Knauf. The villa will be built in Amphilochia, in western Greece, where Knauf currently runs a manufacturing plant. If the experiment is successful, more tremor-resistant homes could be built in earthquake zones across the globe. NMI chief executive Professor Terry Wilkins said, "What we're trying to achieve here is very exciting. We're looking to use polymers in much tougher situations than ever before on a larger scale." Monitors contained in the villa's walls will be able to collect vast amounts of data about the building over time. Wireless sensors will record any stresses and vibrations, as well as temperature, humidity and gas levels. The walls are to be built from new load-bearing steel frames and high-strength gypsum board. Prof Wilkins said, "If there are any problems, the intelligent sensor network will be able to alert residents immediately so they have time to escape. If whole groups of houses are so constructed, we could use a larger network of sensors to get even more information. If the house falls down, we have got hand-held devices that can be used over the ruins to pick out where the embedded sensors are hidden to get some information about how the villa collapsed. Also, we can get information about anyone who may be around, so it potentially becomes a tool for rescue." The aim of the passage is to _ .

Endangered giant pandas are facing a new threat: the loss of their food source, bamboo. In China's Qinling Mountains, giant pandas spend most of their day eating bamboo. The plant makes up 99% of the panda's diet, with some pandas eating about 40 pounds of it a day. But Qinling's pandas may soon have to find another food source. A new study cause the loss of most of the region's bamboo by the end of the century. A team made up of researchers from Michigan State University and the Chinese Academy of Sciences studied the effects of climate change on the region's three main bamboo species. They studied the influence of rising temperatures on the spread and growth of bamboo. Bamboo is sensitive to temperature changes. "Even with a 3.6 degrees Fahrenheit increase in temperature, we found that 80% to 100% of bamboo would be gone by the end of the century," Liu Jianguo, one of the study's authors said. Shirley Martin, who came from Paris but not involved in the team said that it's really a demanding challenge for us to get a desired result. The Qinling Mountains, located in eastern China, are home to about 270 pandas. That is about 17% of the world's wild panda population. The panda is one of the world's most endangered species. In recent years, China has stepped up efforts to protect pandas. But Liu says the country has yet to consider the long-term efforts of climate change in its conservation planning. Aside from increasing nature reserve areas where pandas are protected, Liu wants China to lower its use of fuels that release greenhouse gases-as should the rest of the world.

A San Diego boy Kristoffer Von Hassel has the gaming world' s attention after he exposed a security weakness that let him log into his dad's Xbox Live account, without permission. Kristoffer's father, Robert, noticed soon after Christmas that his son was logging into his account and playing games that weren't appropriate for his age. When he asked how, Kristoffer showed him a hack that seems simple but is fairly impressive considering a 5-year- old found it. Kristoffer would go to his dad's account and type in an incorrect password. That would take him to a password verifications screen, where he would simply tap the space bar repeatedly and then press "enter. " "How awesome is that?" asked Davies, who works in online security himself. "just being 5 years old and being able to find a vulnerability I ty and getting attached to that I thought that was pretty cool."

January 16, 2014 - We know the saying "The early bird gets the worm", but today you're going to learn about the interesting saying "The early fish gets the bird." An African tigerfish was seen jumping out of the air and catching a flying bird. The African tigerfish has bright red fins and very sharp teeth. There have been rumors this kind of fish preys on birds since the 1940s, but no one was able to catch _ . "The whole action of jumping and catching happens so quickly that after we saw it, it took all of us a moment to really understand what we had just seen," said Nico Smit from Environmental Sciences and Management at North-West University. Smit and his research team saw it at a lake in the Mapungubwe National Park in South Africa during summer. They found about 20 fish feeding on birds in the morning. Those birds may be out early to look for food, but we will never know for sure! The tigherfish _ .

Sheng Huizhen's life story is typical of immigrants who have succeeded in America. After getting her PhD in biochemistry, she got a job as a researcher at the National Institutes of Health. She got a green card, bought a house in Maryland and worked her way up all the time. But then she moved back to China. A law in America stopped the use of public money for research on human embryos . This prevented her from doing the kind of work she wanted to do. The Chinese government attracts her to return with $75,000 for a new lab. She could use the lab to do her research. " Maybe because of the culture, the public in China are friendlier to the research," said Sheng, 55 , whose family remains in the United States. Attracted by support and a scientific environment more open to certain types of experiments, China's long-lost scientists are coming back. Besides, China announced that it would double its research-and-development spending by 2012, to about $69 billion. The returning scientists are very happy about that. In recent years, more than 275,000 have come back. Many of these "sea turtles" , as they are known, have returned with degrees in science or engineering. They are going to the Chinese Academy of Sciences, where 81 percent of the members are returning scientists. Fifty thousand of the returning scientists are starting their own companies, according to China's Ministry of Education, pushing the development in science. The best title of the passage is _ .

An astronomer is making a case for launching pop singer Justin Bieber into suborbital space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager -- he would come back down to Earth eventually, after all -- but rather to help jump-start the emerging suborbital spaceflight industry. It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "If there's more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good." Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport. None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z. Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists -- but Shostak is thinking about ways to make it grow. A celebrity launch isn't Shostak's only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling with cameras both inside and out, to give the public dramatic views of every mission. Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry's success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space. What can we infer from the text?
[ "SpaceShipTwo will be the first to fly.", "Famous people will be the main passengers in the future.", "The space trip is still in preparation.", "Every space trip will be made into a film." ]

Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helpera little bird called a honey guide. The honey guide does not actually like honey, but it does like the wax in the beehives . The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or people as it leads them to the nest. When they finally arrive at the nest, _ reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share. Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit. What can be the best title for the text?

Many of us don't pay much attention to the importance of eye care. It is said that if you take care of your body, then you can surely be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place. There are several causes leading to poor eyesight like not enough food, genes and aging . Televisions, computers and reading are also the causes of having poor eyesight. If you happen to work in front of the computer, it is best to take a break every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful things. For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eyesight form UV rays. Eating healthy foods will do good to your eyesight. Remember that vitamins A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person exercises regularly and eats the right kind of food, his eyes will stay in good condition for a long time. All above are natural ways of eye care that help us keep healthy eyes. Being happy all the time can be helpful to a person's eyesight, too.

In earliest times, men considered lightning to be one of the great mysteries of nature. Some ancient people believed that lightning and thunder were the weapons of the gods. In reality, lightning is a flow of electricity formed high above the earth .A single flash of lightning 1.6 kilometers long has enough electricity to light one million light bulbs. The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752.In the same year he also built the first lightning rod . This device protects buildings from being damaged by lightning. Modern science has discovered that one stroke of lightning has a voltage of more than 15 million volts .A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second . Scientists judge that there are about 2, 000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average of one person every day. The safest place to be in case of an electrical storm is in a closed car.Outside, one should go to low ground and not get under trees.Also, one should stay out of water and away from metal fences.Inside a house, people should avoid open doorways and windows and not touch wires or metal things. With lightning, it is better to be safe than sorry! Which of the following is NOT true?

CANBERRA (Reuters Life!) - Think twice before eating those dropped crumbs off your computer keyboard -- you might as well be eating off a toilet seat, according to a new study on the amount of germs on keyboards. A study by British "Which? Computing" asked a microbiologist to examine for bugs on 33 keyboards in a typical London office, a toilet seat and a toilet door handle. Four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had 150 times the pass limit of bacteria -- five times filthier than the swabbed toilet seat. "Most people don't give much thought to the grime that builds up on their PC, but if you don't clean your computer, you might as well eat your lunch off the toilet," said Sarah Kidner, the consumer magazine editor of "Which? Computing" in a statement. The study found that eating lunch at desks is the main cause of a bug-infested keyboard. Dropped crumbs and food encourages the growth of millions of bacteria. Poor personal hygiene, such as not washing hands after going to the toilet, may also add to the dirtiness of keyboards. But despite the health hazard of a dirty keyboard, a survey of 4,000 people by the magazine found one in 10 people ever cleaned their keyboard while another two in 10 never cleaned their mouse. Almost half -- or 46 per cent -- cleaned their keyboard less than once a month. To clear out bugs, the magazine recommends users unplug keyboards, turn them upside down and shake them. Which?

I passed my driving test at the fourth attempt. You might think that means I'm not as safe as someone who passed on their first attempt. But would you feel safer with no driver at all? Maybe not, and that's why automotive firms have included driverassist functions in their driverless cars. This allows the human driver to take over if there is a problem. Google is one producer that has prototype driverless cars. These cars have been newly equipped with autosteering wheels and conventional controls to allow normal driving. But this is just a stage -- the vision is to have fully automated cars very soon. The director of Google's selfdrive project, Chris Urmson, hopes his 11yearold son will never have to take a driving test. To achieve that, the cars need to be on the roads in five years. He says driverless cars will greatly reduce accidents and traffic jams. According to Chris, about 1.2 million people are killed on the roads around the world each year. That number is equivalent to a jet falling out of the sky every day. He thinks gradual changes to existing car designs are not enough to deal with the problems. "If we are really going to make changes to our cities, get rid of parking lots, we need selfdrive cars," he says. Google's prototypes have covered over a million kilometers on the road. They have also had to deal with unexpected situations, such as a child driving a toy car in the road, and a woman in an electric wheelchair chasing a duck. In each case, the car reacted safely. Some are not convinced. Sven Beiker of Stanford University thinks driverless cars will still need human input in extreme circumstances. What can we learn from the text?

On Tuesday, the White House and the U.S. Department of Agriculture (USDA) set new limits on advertising food and drinks in schools. The rules ban advertisements for unhealthy foods in schools. The ad ban includes sugary drinks that account for more than 90% of unhealthy ads. An ad for Coca-Cola, for example, will be removed from a scoreboard at a high school football game. However, ads for Diet Coke and Dasani water, owned by the same company, are allowed to display . The new rules are part of the First Lady's "Let's Move" campaign to fight childhood obesity . Her goal is to get kids to eat healthier food. The marketing limits came after new USDA regulations that put a limit on the calorie, fat and sugar in most school food items. "The idea is simple -- our classrooms should be healthy places," the First Lady Michelle Obama said. "Because when parents are working hard to teach their kids healthy habits at home, their work shouldn't be destroyed by unhealthy messages in schools." However, the healthier food rules are criticized by people who think the government should not control what kids eat and by some students who don't like the healthier foods. It is reported that food companies spend $149 million a year on marketing foods to kids, and many big companies are supporting the new rules. Coca-Cola and PepsiCo have started to advertise healthier products. For schools, junk food ads like the Coca-Cola scoreboard will be taken down. "The new limits ensure that schools remain safe places where kids can learn and eat healthy food," Agriculture Secretary Tom Vilsak said. The rules will help guide schools on ways to create standards for foods and physical activities. They will require parents and the community to be involved in the campaign. What's the main idea of the text?
[ "Having a balanced diet in schools is important.", "New limits on advertising foods in schools have been set.", "It's Michelle's duty to make sure schools are safe places.", "Banning advertisements for Coca-Cola in schools is necessary." ]

The European School Survey Project on Alcohol and Other Drugs infervt6wed 15 and 16 - year olds in 35 countries.26% of boys and 29% of girls in the UK had been addicted to uncontrolled drinking at least three times in the previous month.In the same survey, 42% of boys and 35% of girls admitted they had tried illegal drugs at least once. According to another survey, by the European Monitoring Centre for Drugs and Drug Addiction, two in five 15 - year - olds in the UK have tried cannabis .This number is higher than anywhere else in Europe.The UK has also the common highest number of young cocaine users, together with Spain. The British government has recently made new plans to fight the problem of drug abuse in the United Kingdom, also among teenagers.According to the new proposals, young offenders will have to attend drug treatment as part of community service.British police will be able to give people blood tests for drugs when they arrest them, not just when they charge them with an offence.Drug sellers working near a school or using children to help sell drugs will face tougher penalties . But schools also try to fight the problem of drug use themselves.At the beginning of 2005 a British state school has introduced for the first time _ .Students from a school in Kent will have mouth swabs taken to discover drug use.Each week 20 names will be selected by computer and the swabs sent off to a drug testing laboratory.Results will be available three days later.The school' s head teacher says that no child will be tested against his or her wishes.Children who test positive will not be forced to leave the school, but those who sell drugs will.
