A report on a new software that enables eyes to do the typing appears in Wednesday's edition of the journal Nature. Replacing a keyboard or mouse, eye-scanning-cameras mounted on computers have become necessary tools for people without limbs or those affected with paralysis. The camera tracks the movement of the eye, allowing users to "type" on a virtual keyboard as they look at the screen. And now, researchers from the Cavendish Laboratory at prefix = st1 /CambridgeUniversitysay they have developed software that replaces the standard QWERTY keyboard layout with one that is nearly twice as efficient, more accurate and easier on the eyes. Called Dasher, the prototype program looks into the natural gaze of the eye and makes predictable words and phrases simpler to write. Any off-the-shelf camera capable of scanning eye movement can be used with Dasher, though the person must sit fairly still during the interaction. The letters of the alphabet appear in a single column on the right of the screen, with an underline symbol to represent a space. Each letter is framed by a color1ed box. As the user looks at a particular letter on the right side of the screen and drags it to the left with their eye, another sub-alphabet column begins to emerge inside the box on the right-hand side, along with more letters framed in color1ed boxes. Dasher is designed to anticipate which letter will be needed, so although the successive sub-alphabet columns are initially very small, the letters or combination of letters that appear are most likely to be used next in that sequence. For example, if a person starts with the letter "h", the language models in Dasher will bring up "a" "e" "i" "o" and "u" in the sub-alphabet box, along with a few other possible combinations like "ello" to form the word "hello". Each box has a complete alphabet within it, though the first letters to appear have the highest probability of usage. The letters are then placed together to form a sentence on the left side of the screen. Researchers say people will be able to write up to 25 words per minute with Dasher compared to on-screen keyboards, which they say average about 15 words per minute. With a bit of practice, MacKay said, Dasher offers an easier and more satisfying way for disabled people to communicate, providing them with better tools to write e-mail or create word processor files. Mackay said Dasher could work in most languages. With the new software Dasher, people can type with their eyes through _ .

Look, this is the first plane in the world to be created using the new technology of "3D printing". The airplane was built using only a computer--but it can fly at a speed of 100mph and has a two-meter wingspan. It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a "snap fit" technique so the aircraft could be put together without tools in minutes. No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as "laser sintering "and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost. Professor Jim Scanlon, who led the team, said, "The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing." He added, "This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense." The new printed plane is known as the Southampton University Laser Sintered Aircraft--or SULSA for short--and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s. Professor Jim Scanlon believes they can _ with their techniques.

Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health. This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased.Apple, for example, doesn't want iP hones to come closer to you than 1.5 centimeters; Research In Motion, Blackberry's manufacturer, recommends 2.5 centimeters. If health issues arise from cell phone use, the implications are huge.Voice calls - Americans chat on cell phones 2.26 trillion minutes annually - generate $109 billion for the wireless carriers. Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled. Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population. "Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer. Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says. Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains. Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen. From this passage we can learn that. _ .

When I was a foreign teacher in China,every day I taught English to my students and they taught me about China.One day the topic mined to saying "I love you".I was shocked to learn that not one of my students had said this to their mothers,nor had their mothers said it to them."Does your mom love you?" "Of course,"they answered. "How do you know?" was my logical question.They responded that their moms cooked and Always told them what they were doing wrong to show their earning.I was strummed. So mom's cooking and criticizing read our as "I love you"."Then how do you say 'I love you to her?" They agreed that getting good grades, followed by good jobs would be how they showed their love. I come from a culture where most people are expressive enough,so I repeated these queries in clauses over time.Gradually,I began to get different responses.Some of them had exchanged those sentiments with their moms. One of my favorite stories of change came from a girl.When she came home from university,her mother met her at the door and hugged her.This had never happened before,but her mom said,"Now that you have gone I have more time to myself.I noticed that in some places mothers and children hug each other and I decided it was a good idea and that I would begin hugging you." In my family we all say "I love you" a lot.While it is true that we often say the words without having great depth of feelings at that moment,it is almost like a blessing we give each other. Those three little words carry a world of meaning,even when said as a greeting, but most especially if they are the lax words we say to or hear from those we love.

Grandma was always forgetting things." What's wrong with her?" Anna asked. "We think she's getting old, and she may be ill. We may have to send her to a nursing home so that she can be taken good care of. But we can go to see her and bring her presents, like strawberry ice cream." Mother said. One day, they went to see Grandma at the nursing home. Anna hugged Grandma. "Look," she said, "we've brought you strawberry ice cream!" Grandma didn't say anything. She just took it and began eating. "Do you know who I am?" Anna asked. "You're the girl who brings me ice cream." Grandma said. "Yes, but I'm Anna, your granddaughter. Don't you remember me?" she asked, throwing her arms around the old lady. Grandma smiled, "Remember? Sure. You're the girl who brings me ice cream." Suddenly Anna realized that Grandma would never remember her. "Oh, how I love you, Grandma!" she said. Just then she saw a tear roll down Grandma's cheeks . "Love," she said, "I remember love. n "You see, dear, that's what she wants--love!" Mother said. It's more important to remember love than someone's name. What did Grandma remember?

Anyone who has ever lost keys or money will have wished for a simple but effective way to make sure it never happens again. A US company is trying to help. Using a tiny microchip which is implanted into the arm, they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus. The Verichip is about the size of a grain of rice and works using radio frequency identification technology. At a shop, a radio frequency "reader" would send a signal and the chip in your arm would respond with your unique identity number. That would give the "reader" your financial information, and money could be taken directly from your accounts and you wouldn't even have to reach for your wallet. The company also hopes to include other information on the chip, such as medical records, building security codes and passwords, making life even easier. But not everyone is happy with the developments. Critics say that a lot can go wrong with the chip. A clever thief could build a fake reader that would steal your information without you knowing. So your money could still be stolen. Privacy is a big issue too. Stores, or even the government, only need to track the chip to find out what you buy, how much you spend and where you go. And if you wanted to get rid of your chip, you would need an operation to remove it. Which is true of the Verichip?

Waste Not: Energy from Garbage and Sewage A hundred years ago, gas was collected from rotting sewage and used to light street lamps. New technologies hope to update this concept-tapping garbage as well as human waste-for an energy-hungry world. One promising device is called a microbial fuel cell. It makes electricity much like a hydrogen fuel cell, but it runs off wastewater. Sewage-eating bacteria drive a chemical process that generates current and, as a bonus, helps purify the water. Bruce Logan of Pennsylvania State University and his colleagues have constructed small microbial fuel cells, no bigger than a can that can power various devices, including a small fan. "If you had 100,000 people and you treat their sewage, you could get up to 2.3 megawatts of continuous power, which is enough to supply electricity for 1,500 homes," Logan said. A megawatt is one million watts. A self-sufficient water-treatment device is also something that NASA is interested in. Bruce Rittman of Northwestern University is currently devising a microbial fuel cell that could be used on manned space missions. "You have to recycle everything up in space," Rittman said. "You want to capture food waste and human waste, as well as recycle water." A microbial fuel cell has some advantages over the more traditional method, called an anaerobic digester, which collects the methane, or "biogas," that bacteria belch out when they consume organic material in the absence of oxygen. The methane is later burned to turn a turbine generator. "Instead of going through the intermediate step of combustion, a cell makes the electricity directly," Rittman said. This direct route means that a microbial fuel cell could potentially extract more energy from a given amount of sewage. It also would avoid the pollution that burning methane produces. But both Rittman and Logan are quick to add that cells are still early in development, whereas digesters are in use, mostly in agriculture settings where the concentration of organic material is higher than from urban sewers. What type of energy do microbial fuel cells convert into electrical energy?

The dodo was a ground nesting , flightless bird. An adult dodo could grow to a height of about a meter and weigh between 45-50 pounds. The natural habitat of this kind of bird lay in the forest of Mauritius. Seed and fruits that were found in the forest were the main food of the dodo birds. As they could easily get the food they required in the forest, they didn't need to fly. As time went by, they finally lost the ability to fly. It turned out to be a major disadvantage for dodos, as they were left with no ability to protect themselves against human beings' attacks in their natural habitat, which drove this kind of bird to extinction . The extinction of the dodo started in 1505, when Portuguese sailors set their foot on the Island of Mauritius. Before this, the dodo didn't face any danger. People began to hunt them. It was not long before animals, like cats, pigs and monkeys, were also introduced to the island by humans. When ships arrived, the rats on these ships came onto the land. Though these animals were not able to attack huge dodos, it was easy for them to attack dodos' nests on the ground. These animals continued to feed on dodo eggs. The dodo became a relatively rare bird in Mauritius at the beginning of the 17thcentury, and became extinct in the end. The last reported sighting of a dodo was in 1681. Why did the dodo lose its ability to fly?

It is pretty much a one-way street.While it may"be common for university researchers to try their luck in the commercial world,there is very little traffic in the opposite direction.Pay has always been the biggest _ ,as people with families often feel they cannot afford the drop in salary when moving to a university job.For some industrial scientists,however, the attractions of academia outweigh any financial considerations. Helen Lee took a 70%cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge.Her main reason for returning to academia halfway was to take advantage of the greater freedom to choose research questions.Some areas of research have few chances of a commercial return,and Lee's is one of them. The powerful effect of a salary cut is probably less severe for a scientist in the early stages of an occupation.Guy Grant,now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge,spent two years working for a medicine company before returning to university as a post-doctoral researcher.He took a 30%salary cut but felt it worthwhile for the greater intellectual opportunities. Higher up the ladder,where a pay cut is usually more significant,the demand for scientists with a wealth of experience in industry is forcing universities to make the transition to academia more attractive,according to Lee.Industrial scientists tend to receive training that academics do not,such as how to build a multidisciplinary team,manage budgets and negotiate contracts .They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate,says Lee,perhaps experience in manufacturing practice or product development."Only a small number of undergraduates will continue in an academic occupation.So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent a11 their time on a narrow research project."

Cell phones: is there a cancer link? Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors. Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there's a greater than 95 percent chance that power lines can cause childhood leukemia . Also there's a greater than 90 percent chance that cell phones can cause brain tumors. "It's apparent now that there's a real risk, " said Carpenter. But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. "I don't support warning labels for cell phones, " said Linet. "We don't have the evidence that there's much danger. " Studies so far suggest a weak connection between EMFs and illness-- so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It's funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don't suggest a strong link between cell phone use and cancer risk.

If you're not a fan of KFC's famous Double Down hot dog, don't worry! KFC in the UK is developing a new treat: an edible coffee cup. The product is still in the trial stage and not yet available for purchase, but according to a KFC news report, the treat is made from a unique biscuit, wrapped in sugar paper, and lined with a layer of heat-resistant white chocolate, which helps keep the coffee hot. As you drink the coffee in the cup, the white chocolate lining will begin to melt slowly, and the biscuit begins to soften. But it doesn't end there --- the cups are not only edible, they also have a pleasant smell. KFC partnered with The Robin Collective, an experimental food company, to make the cups with coconut sun cream, freshly cut grass and wild flowers scents. According to the news report, that's because the scents arouse the positive memories we associate with warm weather, sunshine and summer holidays. Sounds ... delicious? A manager at KFC said, "We have been experimenting with the edible packaging in limited quantities to see if it could be a popular product in the market. We believe if our customers occasionally like to have their cake and eat it, why wouldn't they want to have their cup and eat it instead!

Although they are an inexpensive supplier of vitamins,minerals,and high--quality protein,eggs also contain a high level of blood cholesterol ,one of the major causes of heart disease.One egg yolk,in fact,contains a little more than two--thirds of the suggested daily cholesterol limit. This knowledge has caused egg sales to drop in recent years,which in turn has brought about the development of several alternatives to eating regular eggs.One alternative is to eat substitute eggs. These egg substitutes are not real eggs, but they look somewhat like eggs when they are cooked.They have the advantage of having lower cholesterol rates,and they can be scrambled or used in baking.One disadvantage, however,is that they are not good for frying,poaching,or boiling.A second alternative to regular eggs is a new type of eggs,sometimes called"designer''eggs.These eggs are produced by hens that are fed low-fat diets consisting of ingredients such as canola oil,flax,and rice bran.In spite of their diets,however,these hens produce eggs that contain the same amount of cholesterol as regular eggs.Yet,producers of these eggs claim that eating their eggs will not raise the blood cholesterol in humans. Egg producers claim that their product has been described unfairly.They use scientific studies to back up their claim.And in tact studies on the relationship between eggs and human cholesterol levels have brought mixed results.It may be that it is not the type of egg that is the main determinant of cholesterol but the person who is eating the eggs.Some people may be more sensitive to cholesterol from food than other people.In fact,there is evidence that certain dietary fats stimulate the body's production of blood cholesterol.Consequently,while it still makes sense to limit one's intake of eggs,even designer eggs,it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol level. What's the main purpose of this passage?

Ibrahim became disabled after contracting polio when he was three years old. At first his parents, like many other parents of disabled children in Niger, did not want to send him to school. They were worried he would be laughed at by his classmates. Despite his disability, and his parents' doubts, Ibrahim was determined to go to school. "When I was eight," Ibrahim says, "other kids of my age were going to school while I stayed at home. I did not like that. So, I pestered my parents until they finally let me go to school." Ibrahim's parents sent him to a private school nearby. Although the journey to and from school was a short one, it still wasn't easy for Ibrahim. He had to use his hands to help him move along, protecting them with plastic slippers. But at least he was getting an education. However, after only a year in school, Ibrahim's education was interrupted when his parents separated. His mother did not have the means to continue paying for his tuition. In 2007, Ibrahim received some money to be fitted with a leg brace , corrective shoes and his first pair of crutches . Now that he was more mobile than before, the most important thing for him was to find a way to go back to school. "I wanted to start school again last October," Ibrahim says. "After my mother told me she could not afford it, I went to visit some of my relatives for support. And I collected 5,000 francs CFA (US $8) to pay my tuition for half a year. I will find the rest of the money somehow." Ibrahim attends a school in which he is the only disabled student. According to his teacher, he is among the top five students in a class of 55.

TOKYO -- The number of domestic infections cases of influenza A/H1N1 in Japan hits 42 on Sunday after a total of 34 people in Osaka and Hyogo counties were confirmed to have been infected, local media reported. The total number of the infection in the country now stands at 46, including the first four cases contracted abroad. The country is now facing the risk of grass-root outbreak which could lead the WHO to raise its new flu pandemic alert to the highest level of 6 from the current 5, experts has warned. The 34 newly confirmed domestic cases, 11 in Osaka and 23 in Hyogo, included high school students, college students and teachers, the health ministry and local governments said Sunday. Japan on Saturday confirmed the first eight cases of domestic infection on students of a Kobe high school. The later confirmed cases in Osaka are said to have contacted the Kobe students in a volleyball match. Osaka and Hyogo are neighboring in the Kansai region. All of the 42 people had no record of overseas travel. Meanwhile, a total of 143 students at the Kansai Okura Senior High School where many infections in Osaka were found, have shown symptoms of influenza since around Monday, according to local media reports. The privately run school said it will be closed from Monday through Saturday. More than 1,000 educational facilities -- kindergartens, and elementary, junior and senior high schools -- in Osaka and Hyogo counties have decided to suspend classes for certain periods following the confirmation of new flu infections in the counties, Kyodo News reported. The two counties have requested private schools to follow suit. Osaka Governor Toru Hashimoto held a meeting of a new flu task force on Sunday and decided to ask facilities such as movie theaters to suspend operations to prevent the spread of the flu. TV clips showed people in Kansai region started to wear masks in public spaces and rushed to drug stores for buying medicines. The Japanese government on Saturday shifted the stage of its new-flu action program from "a period of overseas outbreak" to "a period of domestic outbreak" and called for companies and schools in the areas concerned to allow individuals to avoid commuting during rush hours. The Kyodo News quoted Masato Tashiro, a member of the World Health Organization's emergency committee, as saying that several hundred people in Japan already may have been infected with the new flu. The purpose of the passage is _ .

What would we do without humour? How would we enjoy speaking with others if we did not use humour to invite a smile or a laugh? And how would we manage in times when we feel sad and lonely? Using humour we lighten up each day, and we find common ground with others. We build healthy relationships with others by knowing what to say and what to do. When our use of humour is successful, we build trust and cooperation. We discover that we are not alone, we learn to accept our mistakes, and we look for the good in others and in ourselves. Most importantly, we create common ground, as humour is an essential skill needed to communicate well with others. A few well-chosen words get the attention of others and make a serious point without their getting defensive . Whether we prefer to be the centre of attention or to be shy and quiet, humour can be adjusted to suit our personality. However, when we lose our sense of humour, we often get critical or defensive, and we blame others or ourselves for what was said, and how it was said. To ensure that our humour is welcomed by others, we need to combine our humour with speaking clearly and listening effectively. Have you ever noticed that successful individuals often use self-depreciating humour to humble themselves, without putting themselves down? These individuals understand that every person has strengths and weaknesses and that self-depreciating humour invites others to feel more confident and equal. In this way, humour is the shortest distance between two people. Humour is the spice of life, as it brings happiness, numbs pain and it makes us speak and listen well. From the passage we can learn that _ .

The US company iRobot made a new kind of sub-marine , called the Seaglider, last week. The robotic submarine was developed by researchers at the University of Washington. It is about 1.8 meters long and weighs about 52 kilograms. It moves through water at a speed of up to 20-25 kilometers a day and can stay at sea for up to six months before needing a battery recharged. This special character results from its special propulsion system . Unlike a traditional submarine, the Seaglider does not have a propeller . It has an air tank that is emptied and filled to adjust depth, as well as a pair of wings that help to guide and lead the submarine. A traditional submarine, on the other hand, "puts water inside tanks to make it heavier, or it will expel the water to make it lighter," explained Frederick, a professor at the University of Washington. Each time the Seaglider comes to the surface, it sends the data which it collects to its controllers by satellite. Operators can also send the submarine new information. For example, they can change its course in their office through giving the computer orders. Seagliders are already being used for scientific research, such as environmental studies. iRobot also hopes to sell the submarine to the military . At $100,000 each, the Seaglider is a cheap way to keep an eye on the ocean. "These things can go out there and monitor large areas of ocean because they're very persistent. They can go for thousands of miles on their own. At the same time, you can tell them to stay in one place and they can circle," says Helen Greiner, chairwoman of iRobot. "This is science fiction stuff in many ways, but it's really out there and working." When the Seaglider comes to the surface, it will _ .

Isn't it astonishing how much time we spend talking about food? "Have you ever eaten ...?" "What did you have for lunch?" and so on. And yet when you travel from one country to another, you will find that people have quite different feelings about food. People often feel that what they eat is normal and that what other people eat is strange or silly. In most parts of Asia, for example, no meal is complete without rice. In England, people eat potatoes every day. In the Middle East, bread is the main part of every meal. Eating like so many things we do, becomes a habit which is difficult to change. Americans like to drink a lot of orange juice and coffee. The English drink tea four or five times every day. Australians drink a great deal of beer, and the French drink wine every day. The sort of meat people like to eat also differs from one country to another. Horse meat is thought to be delicious in France. In Hong Kong, some people enjoy eating snakes. New Zealanders eat sheep, but they never eat goat meat. The Japanese don't like to eat sheep meat because of its smell, but they enjoy eating raw fish . So it seems that although eating is a topic we can talk about for hours, there is very little common sense in what we say it. People everywhere enjoy eating what they have always eaten, and there is very little we can do to change our eating habits. The Japanese don't like to eat sheep meat _ .

Have you seen a yellow-and-black salamander ? How about a scarlet frog? Scientists haven't spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct? Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads , and salamanders are amphibians. The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They're also looking for species in Africa, Asia and Australia. Scientists are hopeful that they'll find the amphibians--and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live. "If researchers can find the missing creatures, they might be able to figure out how to save them," explains expert Robin Moore. He began searching for the amphibians earlier this month. "This search will tell us a lot about how amphibians are doing," Moore told WR News. "I don't know what we will find, but that makes the search even more exciting." Lost in the Wild Scientists' hunt for missing amphibians is under way. Read about some of the species they hope to find. Turkestanian salamander This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since. Gastric brooding frog Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss. Rio Pescado stubfoot toad Last sighting: 1995, in South America Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease. It can be learned from the passage that _ .

Internet use appears to cause a decline in psychological well-being , according to research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less frequently, the two-year study showed. And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling. Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others. The fact that Internet use reduces time available for family and friends may account for the drop in well-being, researchers suggested. Faceless, bodiless "virtual" communication may be less psychologically satisfying than actual conversation, and the relationship formed through it may be shallower. Another possibility is that exposure to the wider world via the Net makes users less satisfied with their lives. "But it's important to remember this is not about the technology _ ; it's about how it is used," says psychologist Christine Riley of Intel, one of the study's sponsors. "It really points to the need for considering social effects in terms of how you design applications and services for technology." The best title for this passage would be _ .

A newly discovered planet looks just right for life as we know it, according to an international group of astronomers. Orbiting a star about 500 light-years away, the planet called Kepler-186f is about the same size as Earth. It orbits its star at the right distance for liquid water on the surface. That is a necessary condition for life as we know it. But it is not exactly like Earth, NASA planetary scientist Elisa Quintana said. "It's more of an Earth's cousin. It's not an Earth's twin. It shares the same characteristics as Earth, but their parent stars are very different," said Quintana. Kepler-186f orbits a star that is smaller and cooler than our sun. But, writing in the journal Science, the astronomers say the planet appears to be a closer than most of the hundreds of others discovered so far. Some are massive gas-covered giants with thick, crushing atmospheres. Others orbit too close to their stars and are too hot for life. Two planets discovered last year are in the right orbit and might be good candidates for life, Quintana says, but they are a bit bigger than Earth. "For the first time, we can actually say we now have a planet that is both Earth-sized and orbits in its star's habitable zone," she said. It may be the first time, but it probably is not the last, says Massachusetts Institute of Technology astrophysicist Sara Seager. "We've been waiting decades to understand how common habitable planets might be, and it's looking like they're really common. And this gives us excitement and motivation to take the next step," said Seager. The next step would be to look for signs of life in the atmospheres of these distant worlds. That would take a more sophisticated (;) space telescope. But budget cuts threaten that mission, says University of California at Los Angeles astrophysicist Ben Zuckerman. "In principle, we could do this in the next few decades. But in practice, because there's no money, it's not gonna happen. It's not gonna happen in my lifetime, for example." Leaving earthbound concerns behind, NASA's Elisa Quintana believes that when the next-generation space telescope is launched, it will find that we are not alone in the universe. According to Elisa Quintana, Kepler-186f _ .

It's so difficult to follow the _ of a 2-year-old. One moment he's beaming and friendly; the next he's sullen and weepy, often for no apparent reason. These mood swings, however, are just part of growing up. They are signs of the emotional changes taking place as your child struggles to take control of actions, impulses, feelings and his body. At this age, your child wants to explore the world and seek adventure. As a result, he'll spend most of his time testing limits, his own, yours and his environments. Unfortunately, he still lacks many of the skills required for the safe accomplishment of everything he needs to do, and he often will need you to protect him. When he oversteps a limit and is pulled back, he often reacts with anger and frustration, possibly with a temper tantrum . He may even strike back by hitting, biting and kicking. At this age, he doesn't have much control over his emotional impulse . So his anger and frustration tend to erupt suddenly in the form of crying, hitting or screaming. It's his only way of dealing with the difficult realities of life. He may even act out in ways that unintentionally harm himself or others. It's all part of being 2. It's not uncommon for toddlers to be angels when you're not around, because they don't trust people enough to test their limits. But with you, your toddler will be willing to try things that may be dangerous or difficult, because he knows you'll rescue him if he gets into trouble. Whatever protest pattern he has developed around the end of his first year will probably persist for some time. For instance, when you're about to leave him with a sitter, he may become angry and throw a tantrum in anticipation of the separation. Or he may cry and cling to you. Or he could simply become subdued and silent. Whatever his behavior, try not to overreact by scolding or punishing him. The best tactic is to reassure him before you leave that you will be back and, when you return, to praise him for being so patient while you are gone. Take comfort in the fact that separations should be much easier by the time he's 3 years old. When a mother is about to separate with her baby, she'd better _ .

Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment. ks5u Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas. ks5u There are many environment-friendly sport. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes;and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control. ks5u Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free. ks5u What do we know about golf from the passage? ks5u

The African elephant, the largest land animal remaining on the earth, is of great importance to African ecosystem . Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna surroundings in which it lives, therefore _ of existence for millions of other animals that live in its habitat. It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas . In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters. Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well. What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem. What is the passage mainly about?

A small dog should be _ after eating a handful M&M's, at least according to conventional wisdom. But watching "Moose", a friend's five-pound Chihuahua, race around a living room after his sweet snack makes one wonder: Is chocolate truly poisonous to dogs? Dogs and humans have similar tastes. But unlike humans, our companions experience dangerous effects from eating chocolate --it can poison them and in some cases is fatal. Chocolate's danger to dogs depends on its quality. Chocolate is processed from the bitter seeds of the cocoa tree, which contain a family of compounds known as methylxanthines . This class of substances includes caffeine and the related chemical theobromine . Chocolate contains a significant amount of theobromine and smaller amounts of caffeine. These chemicals can cause a dog's heart to race up to twice its normal rate, and some dogs may run around as if "they drank a gallon of espresso ," according to Hackett. Dogs are capable of handling some chocolate, but it depends on the animal's weight and the type of chocolate it eats. Unsweetened baking chocolate contains more than six times as much theobromine as milk chocolate, although amounts vary between cocoa beans as well as different brands of chocolate. Less than four ounces of milk chocolate is potentially fatal for Moose and other small dogs. Around every confection-centered holiday -- Valentine's Day, Easter and Christmas -- at least three or four dogs are hospitalized overnight in the animal medical center at Colorado State. But in 16 years, Hackett has seen just one dog die from chocolate poisoning, and he suspects it may have had an underlying disease that made it more exposed to chocolate's heart -racing effect. The passage is mainly about _ .

Blue whales are the largest animals ever known to have existed on the planet, and they can grow to a length of 100 feet and weigh more than 330,000 pounds. But recently researchers have found that these whales are on the move and they have migrated (moved) from California waters to areas off Canada and Alaska for the first time since commercial whaling ended in 1965. The researchers identified 15 blue whales that have appeared off the coast of British Columbia and the Gulf of Alaska since 1997. Four of these whales were recognized as ones that were once sighted off California shores, suggesting that the whales are returning to an old migration pattern between the coasts. Before commercial whaling began in the early 1900s, blue whales were found widely throughout the North Pacific and California waters. But from the 1920s to the 1960s, whaling severely reduced the whale populations. Blue whales never recovered in the Northern Pacific, making sightings in this area rare. However, much larger groups of whales have been observed close to California since the 1970s. The scientists had previously thought that the California population was separate from the population that had historically lived in North Pacific waters. But the current study shows that whales off the coast of British Columbia and the Gulf of Alaska are likely part of the California population.[:] To identify the blue whales, the researchers looked at photos of _ taken in the North Pacific Ocean and compared them with a library of blue whale pictures taken along the West Coast of the United States and Southern Pacific. Up to now, the researchers are not quite sure why the whales are changing their migration patterns, but they suspect that the whales may be following their food moving farther north by the changes in ocean conditions. What might make blue whales migrate according to the researchers?

Celia was shocked. She had always been in good shape during high school, but now, in her first year of college, she was suddenly ten pounds heavier. "My friends and I often had pizza or ice cream when we studied late at night," she said, "and I was always drinking Coke to stay awake." Celia's experience is common. Many students enter college and find it so different that they cannot deal with changes properly. They're away from their parents and in a new stressful environment. Pressures together with freedom to sleep and eat however they please cause many students to experience the "Freshman 15": gaining weight suddenly in their freshman year of college. Most students do not realize that the "Freshman 15" can cause some serious health problems. Of course, college-age adults are still developing bone mass, so gaining some weight is normal. Sudden weight gain, however, puts too much strain on the heart and lungs, resulting in little energy and some difficulty thinking and remembering. In later life, it can lead to heart disease, diabetes, obesity, and possibly cancer. The solution to the "Freshman 15" is simple--pay attention to developing good habits! In general: * Eat normal-sized meals at regular times. Eat slowly and enjoy it, so you don't need to go back for more. * Keep only healthy snacks in your room--and don't snack too often! * Control drinking and smoking. Alcohol has a lot of calories, and smoking too much makes exercise difficult. * Exercise regularly! Even just 30 minutes a day--such as walking quickly to class from your dorm--will make a big difference! What do many students think of their freshman year of college?

The Nobel Prizes in physiology or medicine, physics and chemistry are the most respected prizes in science. But talk to scientists in private, and many will complain why (besides jealousy, perhaps) are some scientists unhappy with the Nobels? One reason is that the committees can often be slow to recognize achievement. Alfred Nobel specified in his will that the prizes should reward work done in the previous year. But experience soon showed that this was risky, as medals were given out for discoveries that later proved questionable. So a degree of caution is probably advisable. Sometimes, though, it can lead to strange results. Subrahmanyan Chandrasekhar, for instance, had to wait until 1983 to win a prize for work he had done in the 1930s on the structure of stars. However, Albert Einstein never won a prize for his theory of relativity. Even though some pretty suggestive evidence had been produced by Arthur Eddington in 1919, relativity, which has later passed every experimental test ever thrown at it, was still considered somewhat risky and obscure. Another criticism concerns the tradition that no more than three people can share a prize. Science is rarely this clear-cut. Take this year's physics prize, which recognised Peter Higgs for predicting the existence of the mass-bestowing particle that now bears his name. Dr Higgs was only one of several people with a claim. Two other teams---- Rober Brout and Francois Englert, as well as Gerald Guralnik, Carl Hageh and Tom Kibble----- submitted papers on the same idea to the same journal that published Dr Higgs's work, all within a few months of each other. Science often works like this, with different people coming up with similar ideas at similar times. In the event, the committee decided to honour Dr Engler (Brout is dead, therefore unqualified), whose paper was earlier than Dr Higgs's but did not explicitly predict a particle, over Dr Guralnik and his collaborators, who were more comprehensive but published a few weeks later.

What will man be like in the future --- in 5,000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, because man is slowly changing all the time. Let us take an example. Man, even five hundred years ago, was shorter than he is today. Now, on average , men are about three inches taller. 500 years is relatively a short period of time, so we may suppose that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still use only about 20% of the brain's capacity . As time goes on, however, we shall have to use our brains more and more, and finally we shall need our brains more and more, and finally we shall need larger ones! This is likely to bring a physical change too. The head, especially the forehead , will grow larger. Nowadays our eyes are used too much. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a long time it is possible that man's eyes will grow stronger. On the other hand, we make use of our arms and legs less. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a lot in modern life. But what about hair? This will probably disappear from the body because it does not serve a useful purpose any longer. In the future, then, both men and women are likely to be hairless. Perhaps all this gives the impression that future man will not be a very attractive person to look at! This may be true.However, future man will still have a lot in common with us. He will still be a person, with thoughts and feelings similar to our own. How much brain's capacity of a person hasn't been used now?

Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend themselves by using both physical and chemical means. Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach. Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth. Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar. Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly leaves, and each prickle contains poisonous venom A single experience with this kind of plant will teach an animal to stay away from it in the future. How does tobacco protect itself against an attack from a caterpillar?

There is a famous English saying "You are what you eat", and _ means what you put in your mouth will become part of you. Many experts use it to tell people it's important to have a good eating habit. For example, too much sweet food makes a person overweight . To avoid being fat, kids are told to keep off sweet food. But, a team of American scientists have found something new about eating sweet food. "When we say some people 'sweet', we mean they are kind and friendly to us. Perhaps this word can help us learn more about people's feelings and acts." said Brian Meier, a scientist from the study team. "Taste is something we experience every day. What we have done is to find whether we can know someone's character and behavior depending on their taste." In one of their experiments , students were asked questions about their character-whether, for example, they were soft-hearted or not. Then they were asked to make a list of their favorite food. According to their answers, the scientists found that the students who liked sweet food were nicer. In their another experiment, the scientists found that people who preferred sweet food such as cookies and chocolate were more willing to help other people in need, and those who ate non-sweet food such as chips weren't. For example, people with a sweet tooth were more likely to volunteer to clean up their city, visit sick children in the hospital and so on. The result of the experiments is that people's helpfulness or being nice has something to do with their taste for sweet food. So eating sweet food is a useful way to make people nice and helpful. Next time, try some ice-cream. ,. The scientists found that the people who preferred _ were less helpful.

What would you think if someone suggested knocking down St Paul's Cathedral to widen the road? Or pulling down Big Ben to make way for a car park? It would be ridiculous, right? But when it comes to devastation of the natural world, we aren't so easily shocked. But we should be...or we'll be in a lot of trouble. _ . Ancient forests are destroyed. Wetlands are becoming dry. Woodland is disappearing, and all in the name of progress. This is bad in itself, but it's devastating for biodiversity. Biodiversity refers to the variety of plants, animals and other living things that are all interconnected. The ecological services provided by biodiversity are vital to everyday life. The air we breathe is a product of photosynthesis by green plants. Insects, worms and bacteria break down waste and make soils rich. And tiny organisms clean the water in rivers and sea. In fact, all life on the earth exists thanks to the benefits of biodiversity. More than 90 percent of the calories consumed by people worldwide are produced from 80 plant species. And 30 percent of medicines are developed from plants and animals. Maintaining a wide diversity of species in each ecosystem is necessary to preserve all living things. The loss of biodiversity could be devastating. "It is wrong to think that biodiversity can be reduced indefinitely without threatening humans," said Harvard University biologist Edward O. Wilson, known as the "father of biodiversity". He warned, "We are about to reach a critical point beyond which biodiversity loss will become irreversible ." But what can we do? The present problem is that the concept of biodiversity is so vague . People might care about giant pandas, but it is much harder to excite them about the fate of tiny sea creatures which are being boiled to death in the cooling systems of power stations along coastlines. TheGuardiannewspaper is trying to help. _ has launched the Biodiversity 100 campaign to try to convince governments around the world to take action to deal with the widespread concerns about biodiversity. This includes persuading the UK government to create a series of marine reserves to reserve the decrease in the sea-life caused by industrial fishing, stopping fishing sharks by the Japanese fishermen and banning the killing of dingoes (wild dogs) in Australia, among many other things. There is a lot to do. And we'd better act quickly if we don't want to end up with a planet that can't sustain life! The writer thinks it _ to pull down Big Ben to make way for a car park.

Glaucoma is a major cause of blindness around the world, especially in developing countries. The World Health Organization says glaucoma is a greater public health challenge than cataracts , because the blindness caused by the latter can be cured after operations. Glaucoma is a disease that makes people around the world lose their sight, and they usually don't even know they have the disease until it has permanently destroyed at least 40 percent of their sight. The process is usually so painless and subtle , so people don't notice it. Actually, the simplest medical test can discover it. "It is the leading cause of blindness in the United States. In Hispanics and in African-Americans, it's the second leading cause of blindness and so is the case in the Chinese and Indians." said Dr. Alan Robin, a specialist in treating glaucoma. "The glaucoma we see in sub-Saharan Africa is a much more aggressive blinding disease than the glaucoma we see in Americans or even African- Americans in-the United States." he said. . Dr. Eric Fleischer also sees at Medstar Washington Hospital Center. "Pretty much anybody who has ancestors in Africa has an increased chance of developing glaucoma." Age is another thing that may lead to glaucoma, although people of all ages can get it. Glaucoma is a group of diseases that commonly produce pressure in the eye. An eye is sort of like a watch. And behind the face of the watch, liquid is made. It goes through your pupil and into the front of the watch between the face and the crystal.There's an area around the edge of the watch that drains the liquid. When that drain is blocked, the liquid can't leave the eye as fast as it is produced. The rising pressure within the eye damages and eventually kills the optic nerve. The result is blindness. Fortunately, if caught early, glaucoma can be controlled. Glaucoma is not curable. But as researchers worldwide lean more about it, they grow more hopeful that glaucoma can one day be cured or even prevented. From the passage, we can learn that, _ .

We have now known something about computers---computers work for us at home, in offices and in factories. But it is also true that many children today are using computers at schools before they can write. What does this mean for the future? Are these children lucky or not? Many people do not know about computers and they think of them as machines that children play with. They worry that children do not learn from experience but just from pressing* a button* and that this is not good for them. They think that children are growing not knowing about the real world. And they are very worried about that their children will lose themselves in the computer games. But many people understand more about computers, they say that computers can be very good for children. A computer can help them to learn about the real world more quickly, to learn what they want to learn and think for themselves. And for the future, don't we need people who can think clearly, who know how to get information quickly and use it well? What do you think? For example, e-mail is very popular at this moment. Do you know about e-mail? E-mail is a way of sending messages to other people. E-mail is a fast and cheap way to keep in touch with friends and family. It's much quicker than sending a letter. People who use e-mail have an e-mail address. This address must have letters and dots* and the symbol "@"meaning "at". This is what an address looks like. People can send the messages across the Internet. It is quick, easy and fun. If you know about computers, you must know the letter "@" means _

Have you seen Avatar(<<>> )? It's a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images from the movie look as if they were coming straight towards you. More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies are more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why? When we look at an object , each eye sees it at a different angle . Our eyes send the two images to our brain , and the brain puts them together. 3D technology uses two film projectors . One projects a left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can't put together the images sent to our eyes. The brain needs to work harder at "reading" the images. That makes it easier for people with eye problems to get dizzy or have headaches. A famous eye doctor said if your eyes can't focus on the same object at once, you will have trouble watching 3D movies. . The 3D glasses can make the images from the movie _ .

Recently, tests have proved that Beethoven died from lead poisoning. Bill Walsh directed the Beethoven Research Project. Mr Walsh and his team examined pieces of bone belonging to Beethoven. They found a large amount of lead in the bone pieces. They said the lead levels were equal to those found in pieces of his hair in earlier studies of other scientists. Genetic tests proved the bone pieces and hair came from Beethoven. The researchers also examined bone fragments( from someone else who lived during the same period. Both were from the top of the skull. The fragments from Beethoven had more lead than those from the other person. Their study didn't find measurable levels of cadmium or mercury , which scientists used to consider were the causes of his health problems. Beethoven was sick for much of his life. He experienced strong stomach pains, a sign of lead poisoning, and a change of personality when he was around 20. He also got angry easily, and suffered from depression and hearing loss. His health problems became worse as Beethoven grew older. Walsh said the lead levels found in Beethoven's skull suggested the metal might have been present in his body for many years. He said although there had been recognized cases of deafness caused by lead poisoning, there was no strong evidence to suggest that lead poisoning was the cause of Beethoven's deafness. Ludwig van Beethoven visited many doctors to find a cure for his health problems. In a letter he wrote to a friend, he asked researchers to examine his body after he died so that other people would not have to suffer as he did. During the research, Walsh and his team didn't _ .

The use of mobile phones over a long period of time can raise the risk for brain tumors , a new Swedish study said on Friday , contradicting (......) the conclusions of other researchers . The Dutch Health Council , in an overview of research from around the world , last year found no evidence radiation from mobile phones and TV towers was harmful . A four-year British survey released in January showed no link between regular . long-term use of cell phones and the most common type of tumor . However , researchers at the Swedish National Institute for Working Life said they looked at the mobile phone use of 905 people between the age of 20 and 80 who had been diagnosed with a malignant brain tumor and found a link " A total 80 of these 905 cases were so-called high users of mobile phones , that is they began early to use mobile and or wireless telephones and used them a lot , " the study said . " The study also shows that the rise in risk is noticeable for tumors on the sided of the head where the phone was said to be used , " it added . Kjell Mild , who led the study , said the figures meant that heavy users of mobile phones , for instance of who make mobile phone calls for 2 , 000 hours or more in their life , had a 240 percent increased risk for a malignant tumor on the side of the head the phone is used . " The way to the risk down is to use handsfree , " he told Reuters .

Some time ago I received a gift from both of my children. It had nothing to do with Father's Day. Yet, at the same time it had everything to do with Father's Day. My son was studying in a high school in Colorado. He lived in the school. While we were talking on the phone he shared some wonderful news with me. He said, "You know Dad, I am really happy with my life. I can't think of a thing that I would change about the way that I grew up, or the way that my life is now. " My daughter was living with her mother in Northern California at that time. She said almost the same thing to me just a few days later. Of course, I was delighted to hear this from both of them. And I told them both how happy I was, not only that they were happy ,but that they expressed it to me. And that was the gift that they were giving me ---with the heart to communicate. Certainly I hope for good news when I hear from them. But mostly I love that they will share their real feelings with me. Happy or sad, I love to be touched by their real thoughts and feelings. For a child, Father's Day isn't really about giving Dad a gift. It is about understanding the love that fathers express when they help put food on the table, teach their child to ride a bike, cheer at a soccer game, etc. For a father, Father's Day isn't so much about receiving gifts for a job well done. Remember, the greatest gift that we give our children is the real expression of our love. It isn't enough for them to feel love inside ourselves: we need to express that love. The writer's son said _ on the phone.

FRIDAY, Aug. 3 (Health Day News) -- Middle school students who are physically fit are likely to score higher on standardized tests measuring reading and math abilities, a new study has found. And, the average scores went up in connection with levels of fitness, the findings showed. "The more physically fit kids were, the higher their scores," said the study's lead author, Trent Petrie, director of the Center for Sport Psychology at the University of North Texas in Denton. "Parents should encourage their kids to be physically active. There are some real cognitive and academic benefits that come from physical fitness", Petrie said. Results of the study are scheduled to be presented Friday at the annual meeting of the American Psychological Association in Orlando, Fla. The study included more than 1,200 middle school students from five schools in a suburban area of Texas, with 561 boys and 650 girls. About 57 percent of the children were white, and nearly one-quarter were Mexican American. Nine percent were black and about 2 percent were of Asian descent. The school district provided the researchers with information on the children's race, age, grade level and whether they qualified for the free school lunch program, which was an indicator of the family's socioeconomic status. The schools also provided scores to the tests, which were given between one and four months after the researchers had assessed the children's levels of fitness. Fitness tests were administered during physical education classes to determine the youngsters' heart and lung health (cardiorespiratory fitness), as well as their body mass index (BMI), an indicator of how much body fat a person has. The children also filled out questionnaires that helped the researchers determine factors such as self-esteem and social support. After accounting for factors such as age, sex, family income and self-esteem, the researchers found that for both boys and girls, higher levels of heart and lung health predicted better scores on both the math and reading tests. For boys, perceived social support also seemed to increase their reading scores, the investigators found. In girls, while being physically fit predicted higher reading scores, so too did a higher BMI-- which indicates more body fat. "We were a little surprised by this finding," Petrie said. "It was not as strong an association as the one with physical fitness," he added. The authors suspect it may have something to do with girls this age entering adolescence, which may be related to a higher BMI and slightly higher brain development. He said he plans to make great effort to look for this relationship again in larger studies to see if it was a chance finding, or if the association holds up. "While we can't say 100 percent that physical fitness causes better academic performance, we can say that there is a strong and predictive relationship between physical fitness and academic performance," Petrie said. "It's hard to tease apart the exact reason for this association," said Becky Hashim, an attending clinical psychologist and assistant professor in the departments of psychiatry and pediatrics at the Children's Hospital of Montefiore, in New York City. "It may be that the children are getting more oxygen. When the heart and lungs are working at a higher capacity, it may allow the brain to work at peak performance. Children who are less fit may be sleepier during school," she noted. "I personally feel that there's probably a strong relationship between the confidence you get from being able to do something physical well and academic performance." Whatever the reason behind this association may be, "there's certainly no harm in pushing physical fitness," Hashim added. "Physical fitness may make you feel better, give you more confidence and improve your performance across the board," she said. Petrie agreed. "Physically fit kids are happier, have higher self-esteem and, tend to have better relationships, and now we're beginning to see that there also seem to be benefits cognitively and academically. Our study sends a strong warning to policymakers to reconsider the service program of physical education classes for kids," he said. What's the suitable title of the passage?

Computer games have been criticised for quite some time over a whole range of issues. Some people say they are overly violent and encourage violent behaviour particularly in children. Others say that they make children unsociable and are bad for their eyes. Some have even attributed falling standards of literacy and a lack of interest in reading on them. Now, however, it seems that computer games have also become a feminist issue. Game manufacturers have, for some time, been looking to increase the number of female game players. The vast majority of computer games still sell to a mainly male market. Perhaps this is because the violent nature of many of the games appeals more to males or perhaps because many of the main characters in the games are male. Manufacturers' attempts to produce more female characters increase their share of the female gaming market which has met with serious criticism from many women's groups. While heroines such as Lara Croft of the Tomb Raider game are seen as providing positive role models of strong women, many believe that the character's unrealistic Barbies are subconsciously setting unattainable standards in the minds of young women. Perhaps a stronger criticism is that although many games now include female characters, their role is often secondary and they support the main, male, action characters within the games. Of course the nature of many of the games remains violent and destructive and this in itself could well continue to put off female gamers. There are now, however, a number of web sites springing up on the World Wide Web to help women deal with this issue. Sites such as Game Girlz, Women Gamers and Game Gal offer game reviews, articles, discussion forums and even employment opportunities for women interested in becoming part of the rapidly expanding games industry. The games are reviewed by women from a very female perspective. Some rate the games from one to ten across a range of criteria which include the appearance of the female characters, the degree of intelligence attributed to them in the game and even the marketing attitude adopted by the company. The sites are obviously looking for games that move away from the very male dominated and violent nature of the majority of computer games. Many of them review games that are more constructive and developmental. Although the common fantasy themes of knights, witches and goblins still exist within these games, the aims are often very different. Instead of destroying opposing armies,the aim of the game can be to make peace with them. With this increased degree of awareness and involvement from women in the games industry many positive changes could be made that could encourage more women and young girls to become enthusiastic about technology. Perhaps we may even find more male gamers moving away from the traditional violent and destructive games towards the more positive values promoted by these more feminine role models, after all Tomb Raider is still one of the most popular computer games on the market, but perhaps that's too much to ask. Manufacturers want to produce more female characters in order to _ .

Students who work during term time to support themselves at university are far more likely to graduate with a poor degree, according to a government-funded study published yesterday. Undergraduates with part-time jobs are a third less likely to get a first or upper second-class degree than other students, harming their career chances. Students from the poorest backgrounds were most likely to take jobs during term because they could not depend on help from their parents. The report, commissioned by the Department for Education and Skills, also found a clear relation between fear of debt and employment in non-graduate jobs. Students from poorer backgrounds are known to be more unwilling to be in debt than those from middle class families. The study of 8,600 people who graduated in 1999 was made by Peter Elias, of Warwick University, and Kate Purcell, from Bristol Business School. They found that twice as many first-class degrees were awarded to students who did not work during term compared with those who did. Between 35 and 38 percent who worked during term achieved a lower second, compared with about 28 percent of those who did not. Professor Elias said that the increase in school fees next year to PS3,000 would have to be monitored carefully for its effect on poorer students. "Higher education is going to be a harder struggle for those who do not come with all the advantages," he said. He suggested that universities could get in touch with employers to provide work experience on good salaries to choose students during holidays, so that they did not have to work during term. Which of the following statements is TRUE according to the passage?

[
"Poor students can't take part-time jobs all the time at university.",
"Employers have the duty to help poor students solve the money problem.",
"First class degrees couldn't be given to the students whose families were poor.",

Every kid wishes to be an adult. Do you remember playing houses as a child pretending to be a grownup like your parents? Did you imagine you were a doctor, a soldier or a teacher? At that time, anything seemed more exciting than young. But now as grownups, some adults find they cannot leave childhood behind. They become "kidults"(kid+adult). Being a kidult has become a lifestyle choice among young people across Asia. Some kidults collect toys they once played with. Hello Kitty, Garfield, and Snoopy have many adult fans around the world. It is not unusual to see a 20something woman with a big, Garfieldshaped cushion on her sofa or a Hello Kitty mobile phone accessory . Other kidults still enjoy children's stories and fairy tales. For example, even an edition of the Harry Potter novels with an adult cover came out in Britain. That way, no one else on the subway will know that an adult is actually reading a children's book! "Kidults can be like vitamins to society. Adults who value their childhood and hold on to pure, childlike emotion may be needed in such a rough and dry society," said a professor in a Korean University. He added that kidult culture might fill the generation gap between adults and kids. It could give children and their parents books, movies, and cartoon shows to enjoy together. Tim Greenhalgh, a professor in London explained that some kidults just refuse to grow up. They cling to childhood because life in a busy and stressful city frightens them. Kidults would like to forget their age and openly show their fear of society and adulthood. "So, they look for an escape from increasingly complex and stressful life that are hard to deal with," Greenhalgh said. According to the passage, kidults would like to do the following except _ .

The father's role in the family is important. One researcher says babies who are cared for by their fathers have greater cognitive development at one year of age than babies not cared for by their fathers. Another researcher reports that by spending time with their pre-school children, fathers can help to develop children's language ability. Researchers also point out that for school-age children, fathers are one bridge with the outside world. Fathers who value education have children who do better in school than those children whose fathers don't value education. What's more, fathers who spend quality time with their children may give their children happy memories which may last a lifetime. While each father is a _ person who educates children in his own style, good fathers have something in common. Good fathers attend their children's school activities. They also involve the children in their lives and the adult world by taking them to see the workplace, or by taking them when the car needs to be repaired, etc. Good fathers expect a great deal from their children, but also accept and support the unique individuals that their children are becoming. Good fathers prefer explanations and reasoning to force. Good fathers know their time with children is really an investment in them. Being an involved father is good for children and good for fathers. Both children and fathers have the chance for growth and development. Today's lifestyles are changing. More and more fathers are keeping a balance between their personal life, work, and family time. According to the passage, we can find that _ .

Many people hurt their backs when they try to lift heavy things from the floor. It is easy to hurt your back muscle when you try to pick up a heavy thing. However, there is a correct way to lift things from the floor. If you pick up heavy things correctly, you probably will not hurt your back. To lift something from the floor correctly, first bend your knees and lower yourself. Keep your back straight. Do not bent over, from your waist keep your back and hips and waist in a line. If you bent over, the muscles in your lower back can became hurt very easily. If you keep your back and hips straight, the muscles are stronger, because they hold up together. The other muscles can then help the lower back muscles. As you lower yourself, try to get as close to thing as you can, put one knee on each side of the thing. Remember at all times to keep your back straight. Put your hand under the thing that is in front of you, between y our knees. To lift the thing, you should stand up slowly. Use your leg muscles in order to stand up. lift with your legs, not with your back. Which part of your body is more easily to be hurt when you lift heavy things?

CALCUTTA, India Mar 24, 2006 (AP) -- One of the world's oldest creatures, a giant tortoise believed to have been about 250 years old, has died in the Calcutta zoo where it spent more than half its long life. Addwaita, which means "the one and only" in the local Bengali language, was one of four Aldabra tortoises brought to India by British sailors in the 18th century. Zoo officials say he was a gift for Lord Robert Clive of the East India Company, who was instrumental in establishing British colonial rule in India, before he returned to England in 1767. Long after the other three tortoises died, Addwaita continued to thrive , living in Clive's garden before being moved to the zoo in 1875. "According to records in the zoo, the age of the giant tortoise, Addwaita, who died on Wednesday, would be about 250 years," said zoo director Subir Chowdhury. That would have made him much older than the world's oldest documented living animal: Harriet, a 176-year-old Galapagos tortoise who lives at the Australia Zoo north of Brisbane, according to the zoo's Web site. She was taken from the island of Isla Santa Cruz by Charles Darwin in the 19th century. Aldabra tortoises come from the Aldabra atoll in the Seychelle islands in the Indian Ocean, and often live to more than 100 years of age. Males can weigh up to 550 pounds. Addwaita, the zoo's biggest attraction, had been unwell for the last few days, said local Forest Minister Jogesh Burman. "We were keeping a watch on him. When the zoo keepers went to his enclosure on Wednesday they found him dead," Burman said. Now, the oldest animal in the world is about at _ according to the passage.

A chocolate printer that allows sweet lovers to create 3D desserts by themselves is to go on sale at a cost of 2,500 pounds. The machine squirts out chocolate and, via computer instructions, allows the user to build any shape they like out of the food. But makers Choc Edge have missed the Easter rush. Even so, they hope the printer will be snapped up by retailers immediately they come to the market. Britain's biggest chocolatiers Thornton's have already said they are interested. Because of the high cost, however, few individuals are likely to buy one. But the devicecould one day allow people to design their own 3D objects after submitting their designs on a website. Dr Hao, founder of Choc Edge came up with a prototype last year and has only just perfected it so that it can now go on sale. "We've improved and simplified the machine, so now it is really easy to use," he told the BBC. "You just need to melt some chocolate, fill a syringe that is stored in the printer, and get creative printing of your chocolate." 3D printing is a technology where a three dimensional object is created by building up successive layers of material. The technology is already used in industry to produce plastic and metal products, but this is the first time the principles have been applied to chocolate. The research has presented many challenges. Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles. Dr Hao said, "What makes this technology special is that users will be able to design and make their own products. From reproducing the shape of a child's favourite toy to a friend's face, the possibilities are endless. It could be developed to help consumers design many products from different materials, but we've started with chocolate as it is easily available, low cost and harmless." "There is also no wastage as any spoilage can be eaten." Dr Hao added, "Eventually we may see many mass-produced products replaced by unique designs created by the customer."[:] EPSRC chief executive Professor Dave Delpy said, "This is a good example of how creative research can be applied to create new manufacturing and retail ideas. By combining developments in engineering with the commercial potential of the digital economy,We can see the new market prospect --creating new jobs and, in this case, the chocolate printer is called sweet business opportunities." Which is the advantage of the chocolate printer?

Some time ago, a friend of mine punished his three-year-old daughter for wasting a roll of gold wrapping paper. Money was tight , and he became infuriated when the child tried to decorate a box to put under the Christmas tree. Nevertheless, the little girl brought the gift to her father the next morning and said, "This is for you, Daddy." He was embarrassed by his earlier over-reaction, but his anger flared again when he found that the box was empty. He shouted at her loudly, "Don't you know that when you give someone a present, there's supposed to be something inside of it?" The little girl looked up at him with tears in her eyes and said, "Oh, Daddy, it's not empty. I blew kisses in the box. I filled it with my love. All for you, Daddy." The father was crushed. He put his arms around his little girl, and he begged her for forgiveness . My friend told me that he kept that gold box by his bed for years. Whenever he was discouraged, he would take out an imaginary kiss and remember the love of the child who had put it there. In a very real sense, each of us as parents has been given a gold container filled with unconditional love and kisses from our children. There is no more precious possession anyone could hold. Why did the father punish his daughter?

Does solving a math problem give you a headache? Do you feel nervous when you sit a math exam? For most students, math can be tough but scientists have proved that math problems can actually trigger physical pain. Scientists came to his conclusion with an in-depth experiment, which was published in the Public Library of Science One journal. They began by finding out how much participants fear math. Those involved were asked a series of questions such as how they feel when they receive a math textbook or when they walk into a math lesson. Based on their answers, participants were divided into groups. One group was made up of people who were particularly afraid of math and participants in the other group were more comfortable with the subject. Both groups were then given either math tasks or word tasks. When a math task was going to come next, a yellow circle would appear but when a word task was soon to come, a blue square would be shown. Using a brain-scan machine, scientists noticed that whenever people from Group One saw a yellow circle, their brain would respond in a way similar to when their body is feeling pain. It was like the pain they would fee, for example, if they burnt their hand on a hot stove. But they reacted less strongly when they knew that they would be faced with a word task. However, scientists saw no strong brain response from people in the second group. Math can be difficult, and for those with high levels of mathematics-anxiety (HMA), math is associated with tension, apprehension and fear. "When you are really thinking about the math problems, your mind is racing and you are worrying about all the things that could go wrong," explained Ian Lyons from University of Chicago, US, leader of the study. "The higher a person's anxiety of a maths task, the more he activated brain regions associated with threat detection, and the experience of pain." More interestingly, the brain activity disappeared when participants actually started dealing with the math tasks. "This means that it's not that math itself hurts; rather, the anticipation of math is painful," Lyons said. Based on the study, scientists suggested that things could be done to help students worry less and move past their fear of math, which might mean they perform better in tests. What can be concluded from the experiment?
|
[
"The anticipation of math has no relation to students' confidence in math.",
"Moderate mathematic anxiety promotes students' academic performance.",
"Physical pain caused by HMA disappears in the process of doing math problem.",
"Effective solutions have been worked out to lower students' anxiety of math."

The yellow-throated longclaw is a bird that lives on the dry savanna of Africa. It looks almost exactly like another bird, the western meadowlark of North America. Although the birds look very similar, they are not even in the same taxonomic family. Scientists think the birds look alike because the two species developed under similar environmental pressures, even though they developed thousands of miles apart. Which process does their development demonstrate?

Lichens are difficult to see. They don't move. They often mix into the living place. You might not even recognize one if you are looking right at it. Lichens live on rocks, branches, houses, and even metal street signs. You can find these colorful organisms almost everywhere -- from deserts to rainforests, and from Antarctica to Africa. They've traveled in outer space, and some scientists think there might even be lichens on Mars. What you probably don't realize is that a lichen is more than a single thing. It includes two different types of living organisms: a fungus and an alga . Neither of these organisms is a plant, so the lichen isn't a plant either. Through photosynthesis , the alga gets the sun's energy to make food for the fungus, which is the place for the alga to live in. However, the alga cannot leave the fungus. Around the world, scientists have found tens of thousands of types of lichens. Many may not even have been discovered yet. As scientists continue to find new kinds of lichens, they are also working to understand how they are connected to one another. By putting together a lichen family tree, they hope to understand why so many different types of lichens have grown in so many places around the world. Many researchers are trying to understand basic facts about the organisms and their connections. Researchers are also using lichens to examine the health of the environment. What do we know about lichens according to the passage?

Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful animals feeding on meat. They feast on marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches (ten centimeters) long. They are known to grab seals right off the ice. They also eat fish, squid , and seabirds. Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator . Killer whales hunt in deadly groups, family groups of up to 40 individuals. There appear to be both permanent and temporary group populations of killer whales. These different groups may hunt different animals and use different techniques to catch them. Permanent groups tend to prefer fish, while temporary groups target marine mammals. All groups use effective, cooperative hunting techniques that some are similar to the behavior of wolf packs. Whales make a wide variety of communicative sounds, and each group has various noises that its members will recognize even at a distance. They use echolocation to communicate and hunt, making sounds that travel underwater until they meet objects, then reflect back, showing their location, size, and shape. Killer whales are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a 17-month pregnancy. Killer whales are immediately recognizable by their special black-and-white coloring and are the intelligent, trainable stars of many aquarium shows. Killer whales have never been widely hunted by humans. Killer Whale are often seen in some aquarium shows because _ .
