Most parents love the Internet and want their kids to use it. But a new survey in America finds almost as many also fear the online world--especially social networking sites such as My Space--and worry their kids will get in trouble with people they meet. "The parents see the web's incredible potential , and they know their kids have to be there." says James Steyer, CEO of Common Sense Media, which released results from a survey that looked into parental attitudes toward the Internet. " is also what they are scared of most." The study was conducted online May 5-10 by Insight Research Group. It says 80% of parents are concerned about kids meeting bad people online. That's because young people who largely have grown up with the Net think of it as a social outlet , say the researchers. To young people, the benefits of giving out some personal information to reach out to friends outweigh the risks. And the study shows they are so comfortable with the medium that 78% have a personal website or blog. Parents also recognize the importance of the Internet. The survey shows 91% think the Net helps their children explore their passions, and 77% think the Internet is one of the most valuable education tools teens have. But 88% think it's important to know what their kids are doing online. Findings suggest both parents and teens need more education about using online media, Steyer says. Internet safety has become an increasing concern for parents in America. Organizations like the Non-profit Common Sense have been trying to reach and help parents pay attention to the problem. Why do young people give out their personal information?

There is a famous saying from the French politician J.A. Brillat-Savarin that goes: "Tell me what kind of food you eat, and I will tell you what kind of man you are." It can be easy to not really think about what you eat. For example, whenever you go into a supermarket to buy a drink, it is all too easy to pick up an ice cream or a piece of chocolate as well. You might not even really want them, but sometimes their bright, nice packaging can be too hard to refuse. So, in our special food magazine we will show you why you should really pay more attention to what you eat! Food not only influences our health but also our beliefs, customs and personalities. The first article will look at the way fast food is leading to obesity . The famous cook, Jamie Oliver, has made it his purpose to introduce ideas about healthy eating. In a speech, Jamie Oliver told the world that during the 18 minutes that he gave his speech, four Americans would die because of the food that they ate! Obesity is also a growing problem in China. As China Daily reported in February, the number of obese people under the age of 18 in China has reached 120 million. Jamie has worked for 10 years to try and fight this problem. Learning about food is important not just because of health problems but also because many people still don't have enough food today. And we know as the improvement of science sometimes we have to face genetically modified food. Don't worry - we'll make you know more about all these topics in our special article! We'll also tell you something interesting about food. For example, do you know what the largest food on the menu is all over the world? It's the roasted camel and it has been served for several hundred years, often stuffed with chicken, lamb, egg, fish and rice! Hopefully by the time you finish reading this edition , you'll pay more attention to the food that you eat. As Oliver says, food is something that can help us enjoy our life. It is important that we love it! Someone is too fat , maybe because he eats too much _ .

It seems that there's a good reason why dogs are always seen as man's best friend. Scientists have found that dogs are the only animals that can read emotion in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry. When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person's face first. A possible reason for this is that the right side of the human face is better at expressing emotions. Scientists have now shown that pet dogs also have "left gaze bias ", but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo showed 17 dogs pictures of human, dog and monkey faces as well as something else with his team. The dogs' eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs. Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions. "Recent studies show that the right side of our faces can express emotions better than the left. If true, then it makes sense for dogs and humans to see the right hand side of a face first." The passage mainly wants to tell us that _ .

Long before the scientific world became concerned about the impacts of introducing nonnative species,a total of l00 starlings were released in New York City's Central Park.Eugene Schieffelin was a Shakespeare lover who wanted to bring to America as manv birds as possible mentioned by the Bard in his poems.He imported 60 starlings and released them on a March day in Central Park.A year later,he introduced an additional 40 birds. Within 50 years,they had spread to every state,and today they number an estimated 200 million.In San Diego County,the starling seems at home in both urban and agricultural environments,frequently feeding on the ground,where it probes lawns and fields for insects,worms and snails. Nesting begins in March and peaks in May when the young birds join large flocks in places like Lake Henshaw,dairy farms or Ramona Grasslands.They frequently take over the nest of other birds,and they don't seem particular,having been observed nesting in many kinds of trees. In addition to competing with native species for food and nesting locations,there have been estimates that starlings cause at least MYM800 million in crop damage annually.Much of the damage they cause is the result of their concentrations.Massive flocks of birds are, though beautiful,can be destructive,even dangerous to aircraft,with more than 800 incidents reported by the Federal Aviation Administration. Despite their bad press,the starling is popular with bird--watchers and also the Shakespeare lovers,who often refer to the starling probably because the bird is quite an imitator.It can imitate the calls of up to 20 other species,including hawks,robins and flickers. Love him or hate him,Schieffelin's release of 100 European starlings had a lasting impact in the United States.He had no idea that he also proved the famous words of Shakespeare."What's done cannot be undone.'' What's done cannot be undone''at the end of the passage can be best explained as _ "

Work your brain! Between 2 and 3 pounds of wonder, it controls everything we say, do or think, who we are and what we care about, the way we walk or laugh or figure out things, what we like and the talents we possess, how we see and talk and run and jump and process our food. The brain uses 20 percent of our body's oxygen and 20 percent of its blood. Somewhere within its protein, fat, 100,000 miles of blood vessels and 100 billion nerve cells, it helps us remember where we put our gym shoes. Change our temperature so we don't die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orangeflavored drinks. Its complexity are stunning, far beyond anything most of us can imagine. To keep this work of art as polished as possible we need to eat right, exercise and keep mentally stimulated. Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone in our brain that improves memory. Mental stimulation keeps you sharp even as you age. "It's very important that we tell people to be physically active and mentally active," said neurologist Malcolm Stewart. "People cannot stop aging, but you're able to reduce the damage; you're able to keep the function up." Following are Dr.Stewart's advice for improving brain health: l Nutrition Avoid fast food. Follow the old adage : For breakfast, eat like a king; for lunch, like a queen; for supper, like a beggar. l Exercise Do a combination of stretching aerobic and musclestrengthening every day. l Mental games Try to have a sense of hope about the future. Do puzzles. Listen to music. Reach out to others to make their lives better. According to the text,more exercise _ .

The failed Skylab will come screaming home to the earth in disappointment sometime next month, but we don't know where it will fall. That precise information is beyond even the calculations of scientist and their computers. The best they can tell us is that the space station, weighting 77 tons and as high as a 12-story building, will break into hundreds of pieces that will be scattered across a track 100 miles wide and 4,000miles long. We are again exposed to one of those unexpected adventures, or misadventures, of science that attract our attention from the boring routines of daily existence and encourages us to think a lot about man's future. What worries Richard Smith, the Skylab's director, is the "big pieces" that will come through the atmosphere. Two lumps, weighing 2 tons each, and ten, weighing at least 1,000 pounds each, will come in at a speed of hundred of miles an hour, and if they crash on land they will dig holes up to 100 feet deep. What worries us, with our lack of scientific knowledge and our quick imagination, is both the big and little pieces, although project officials say there is a very small chance that anyone will be injured by them. That's good to know, but it doesn't remove the doubt of the millions who still remember the nuclear accident at Three Mile Island. That accident took place in 1979 in spite of what scientists had assured(...) us as to the safety of the nuclear reactor . The broken Skylab will come into view _ .

Many people go to school for an education. They learn languages, history, politics, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet, no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher's job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves. It is always more important to know how to study by oneself than to memorize some facts or a formula . It is actually quite easy to learn a certain fact in history or a formula in math. But it is very difficult to use a formula in working out a math problem. Great scientists before us didn't get everything from school. Their teachers only showed them the way. Edison didn't even finish primary school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they knew how to study. They read books that were not taught at school. They would ask many questions as they read. They did thousands of experiments. They worked hard all their lives, wasting not a single moment. Above all, they knew how to use their brain. How did great scientists study?

I have been a special education teacher for 17 years and I wish more people would get into special education.The position is very demanding and there is always a shortage of special education teachers.It is not an easy profession to get into. One needs a BA in education and then a special education certificate such as a certificate in learning disabilities, emotional disabilities or cross categories which means covering all the subjects.A certified new special educate teacher needs to _ a current special education teacher for at least, a year because there is that much to know and practice. Working with the students is the biggest reward.However, the paperwork is huge with requesting more year after year.If you are good at doing about ten things at the same time, then you may be the right person for the job. No day is the same. Parent and government expectations are high. A sense of empathy(the ability of feeling and sharing another person's feelings) and one hundred percent prepared to help your students is important. Also, if you are a special education teacher working in the high school, it is your job to make sure your special education students are able to be employed after they graduate, and then the special education teacher needs to stay in touch with the special students a year after they graduate to make sure they are employed and can support themselves. Education is a very political field next to working in politics. One needs to know what to say, when to say it and make sure it is a benefit for everyone involved. It is a mixture of knowing medical diagnosis and teaching with that in mind. Your record needs to be perfect, and it would also help to be a very strong Christian because you will need to pray often to yourself. This position is not about the money but more of a service. To become a special teacher, one needs _ .

Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers. Their study found that theobromine , found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present. The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. "While coughing is not necessarily harmful it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem," said Professor Peter Barnes. Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicines are stopping coughs. The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they needed only slightly higher levers of capsaicin to cause a cough compared with the placebo. The researchers said that theobromine worked by keeping down a nerve activity , which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness. Which of the following would be the best title for the text?

You may have noticed something different when you ate at your favorite restaurant. Or perhaps you picked up on it while looking through your social media apps . You guessed it ---we're becoming a foodie culture. For some, that means photographing every dish, but others are taking it one step further. Sophia Hampton, a senior at Staples High School in US, chooses to make her own food. She has been published in Future Chefs, a cookbook of recipes by teens. Hampton's best advice for those who want to be foodies is to get in the kitchen. "Start cooking," she said. "There are so many resources online, like recipes and articles about food. Go to your local farmers' market and start cooking with them. Besides blogs and online resources, there are also hands-on cooking classes for students. The Chopping Block, a Chicago cooking school, offers many different classes for teens, including courses on chocolate and French food. By attending cooking classes, surfing online and going to restaurants, you can find endless recipes. But sometimes becoming a real foodie means being behind a camera. As our food-loving culture becomes more popular and teen-friendly, social media apps like Facebook, have become major players in food culture. "Getting involved in foodie culture is as easy as having a camera and a social media app," one foodie said. "I always go to streets and farmers' markets to take beautiful pictures of food. Wherever food prices are expensive, the photos are free." What has made foodie culture more popular, according to the article?

Through a series of experiments an American scientist has gained an understanding of the social structure of the most complex of ant societies. The ants examined are the only creatures other than man to have given up hunting and collecting for a completely agricultural way of life. In their underground nests they cultivate gardens on soil made from finely chopped leaves. This is a complex operation requiring considerable division of labour. The workers of this type of ants can be divided into four groups according to the size. Each of the groups performs a particular set of jobs. The making and care of the gardens and the nursing of the young ants are done by the smallest workers. Slightly larger workers are responsible for chopping up leaves to make them suitable for use in the gardens and for cleaning the nest. A third group of still larger ants do the construction work and collect fresh leaves from outside the nest. The largest are the soldier ants, responsible for defending the nest. To find out how good the various size-groups are at different tasks, the scientist measured the amount of work done by the ants against the amount of energy they used. He examined first the gathering and carrying of leaves. He selected one of the size-groups, and then measured how efficiently these ants could find leaves and run back to the nest. Then he repeated the experiment for each of the other size-groups. In this way he could see whether any group could do the job more efficiently than the group normally undertaking it. The intermediate-sized ants that normally perform this task proved to be the most efficient for their energy costs, but when the scientist examined the whole set of jobs performed by each group of ants it appeared that some sizes of worker ant were not ideally suited to the particular jobs they performed. It seems that smaller ants perform more of the _ .

Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to determine which experiences can influence healthy development in people. Researchers at the institute note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other people. The researchers say this ability to learn exists in a baby even before birth. They say newborn babies can recognize and understand sounds they heard while they were still developing inside their mothers. Another study has suggested that low birth weight babies with no evidence of disability may be more likely than other children to have physical and mental problems. American researchers studied almost five hundred boys and girls. They were born in, or admitted to, one of three hospitals in New Jersey between 1984 and 1987. At birth, each child weighed fewer than two thousand grams. The boys and girls had an average age of sixteen at the time of the study. They were asked to complete intelligence and motor skill tests in their homes. Their test results were compared with those of other children their age. The Eunice Kennedy Shriver National Institute of Child Health and Human Development tries to find out _ .

There are 365 days in a year. We sleep 8 hours a day, so we have 122 days for sleeping. Then our work time has 243 days left. But there are 52 weekends in a year. Each weekend is two days. We lose another 104 days a year for work. It takes us about one hour to have breakfast and supper. This comes to 15 days over a year. But we can't work all that time-we need a holiday. Let's say we have three weeks' holiday. We don't work all day. Four free hours each evening takes up 61 days. We have to remember that we get 2 days' holiday at Easter, 3 at Christmas and 1 at the New Year. There are also 4 Bank holidays. Take those 10 days away and we have 32 days for work. But then we have one and a half hours' lunch every day, and half an hour's coffee break. That comes to 30 days a year. This means that we have only a few days left for work every year! According to the passage, we know that we don't have _ time to work every year.

Adding math talk to story time at home is a winning factor for children's math achievement, according to a new research from the University of Chicago. The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together. Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math. Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement. The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement. "Many Americans experience high levels of anxiety when they have to solve a math problem, with a majority of adults feeling at least some worries about math," said Beilock, professor in Psychology and author of Choke, a book about stress and performance. "These math-anxious parents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way." Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children's math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math. The more times parents and children in the math group used the app, the higher children's achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar students in the reading group by almost three months in math achievement at year's end. The previous study found that _ .

It just may be the world's most costly vacuum cleaner ( ). The price of CleanSpace One is eleven million dollars. But yet, it has a big job to do. Recently, researchers in Switzerland said they planned to build this new cleaning machine. CleanSpace One will not be for use in homes or businesses. It will be shot into space to help remove thousands of pieces of space junk floating around up there. Last year, we reported on the problem of space junk. Over time, many unused spacecraft have hit each other far above the Earth. Big pieces break into thousands of small pieces. Sometimes they fall back into the atmosphere and burn up. But when they do not, it creates big problems. Scientists fear that if something is not done to remove these objects, it may soon become too dangerous to send people and machines into space. There is a large chance that they might hit some of this junk. So that is why the Swiss researchers are developing the new machine. CleanSpace One is not really a vacuum cleaner. It will not be used to take away space junk. But scientists plan to move it close to an old satellite that is no longer being used. Then a claw-like instrument will catch the satellite, and force it back through the atmosphere. There, the satellite will be destroyed by the heat of friction with the air. Researchers say that all they need to do is slow down the speed of some of these unwanted objects. Once they begin to move more slowly, they will fall back to the Earth. There is little chance that they will fall through the atmosphere and harm the people or things below. Unwanted objects will fall back to the Earth when _ .

Carbon monoxide poisoning kills and injures many people and animals around the world. The gas has been a problem since people first began burning fuels to cook food or to create heat. It is a problem in all parts of the world that experience cold weather. Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color1. It has no taste. It has no smell. It does not cause burning eyes. And it does not cause people to cough. But it is very deadly. It robs the body of its ability to use oxygen. Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues. It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage to the body can begin very quickly from large amounts of carbon monoxide. How quickly this happens depends on the length of time a person is breathing the gas and the amount of the gas he or she breathes in. Carbon monoxide poisoning has warning signs. But people have to be awake to recognize them. Small amounts of the gas will cause a person's head to hurt. He or she may begin to feel tired. The person may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly. People develop severe head pain as the amount of gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomach pains. Medical experts say carbon monoxide affects people differently. For example, a small child will experience health problems or die much quicker than an adult will. The general health of the person or his or her age can also be important. An older adult with health problems may suffer the effects of carbon monoxide more quickly than a younger person with no health problems. People with heart disease may suffer chest pains. They may begin to have trouble breathing. Why is carbon monoxide called the silent killer?

Homeownership has let us down. For generations, Americans believed that owning a home was undoubtedly good. Our political leaders hammered home the point. Franklin Roosevelt held that a country of homeowners was "unconquerable." Homeownership could even save babies, save children, save families and save America. A house with a lawn and a fence wasn't just a nice place to live in or a risk-free investment; it was a way to transform a nation. No wonder leaders of all political types wanted to spend more than $100 billion a year on subsidies and tax breaks to encourage people to buy. But the dark side of homeownership is now all too apparent: Indeed, easy lending stimulated by the cult of homeownership may have caused the financial crisis. Housing remains a drag on the economy. Existing-home sales in April dropped 27% from the prior month, worsening fears of a double-drop. And all that is just the obvious tale of a housing bubble and what happened when it popped. _ For the better part of a century, politics, industry and culture lined up to create a fetish of the idea of buying a house. Homeownership has done plenty of good over the decades; it has provided stability to tens of millions of families. Yet by idealizing the act of buying a home, we have ignored the downsides. In the bubble years, lending standards slipped dramatically, allowing many Americans to put far too much of their income into paying for their housing. And we ignored longer-term phenomena too. Homeownership contributed to the hollowing out of cities and kept renters out of the best neighborhoods. It fed America's overuse of energy and oil. It made it more difficult for those who had lost a job to find another. Perhaps worst of all, it helped us become casually self-deceiving: By telling ourselves that homeownership was a pathway to wealth and stable communities and better test scores, we avoided dealing with these frightening issues head-on. Now, as the U.S. recovers from the biggest housing bust since the Great Depression, it is time to rethink how realistic our expectations of homeownership are--and how much money we want to spend chasing them. Many argue that homeownership should not be a goal pursued at all costs. What is the author's attitude towards homeownership?

Researchers recently found that hackers took control of 300,000 home routers . Once your home router has been controlled, hackers could redirect your network to malicious websites controlled by hi-tech thieves who could then steal your online back details and other sensitive data. However, there are some simple steps you can take to protect your router. Say no to 12345 passwords First, never leave your router open without a password and make sure you change both your Wi-Fi and router login password from the default one it comes with. If you use the default password , this could give someone access to the router setup, which could allow them to change your router settings, including viewing any security keys. Don't broadcast it Make sure you don't show up in other people's wireless network scans. Know your network name so you can easily enter it into any devices you want to access that network. Other people do not need to know your network name. To prevent outsiders from seeing your network's name and attempting to join your wireless network, turn off broadcasting in your router's settings. Invite only please One way you can ensure no one else joins your network without your permission is to enable your router to only allow certain devices to connect, and ban all others. To do that you can filter by media access control (MAC) addresses. Turn it off This is a simple piece of advice that can go a very long way in keeping you safe. Simply turn off your router when you're not using your network. If you're at work all day and no one's home, why keep it running? Build a firewall The firewall built into your router prevents hackers on the internet from getting access to your PC so it's always worth enabling it to help add an extra layer of security. However, it does nothing to stop people in range of your Wi-Fi signal from getting onto your network - and as said, a router in the wrong place means your Wi-Fi signal could reach pretty far. For further protection, you should run software firewalls on the individual PCs on your networks. The purpose of the passage is to tell _ .

Inventor, physicist, surveyor, astronomer, biologist, artist... Robert Hooke was all there and more. Some say he was the greatest experimental scientist of the 17th century. In the course of his work, he cooperated with famous men of science like Isaac Newton, and the great architect, Christopher Wren. Hooke's early education began at home, under the guidance of his father. He entered Westminster School at the age of 13, and from there went to Oxford, where he came in contact with some of the best scientists in England. Hooke impressed them with his skills at designing experiments and inventing instruments. In 1662, at he age of 28, he was named Curator of Experiments at the newly formed Royal Society of London- meaning that he was responsible for demonstrating new experiments at the society's weekly meeting. Hooke accepted the job, even though he knew that the society had no money to pay him! Watching living things through a microscope was one of his favourite pastimes . He invented a compound microscope for this purpose. One day while observing a cork under a microscope, he saw honeycomb-like structures. There were cells -the smallest units of life. In fact, it was Hooke who invented the term "cell" as the boxlike cells of the cork reminded him of the cells of a monastery . Another achievement of Hooke's was his book Micrographia, which introduced the enormous potential of the microscope. It contains fascinating drawings of the thing he saw under the microscope. The book also includes, among other things, ideas on gravity, light and combustion that may have helped scientists like Newton when they were developing their own theories on these phenomena . Hooke made valuable contributions to astronomy too. A crater on the moon is named after him in honour of his services to this branch of science. Which is the possible reason why Hooke accepted the job as Curator of Experiments?

For hundreds Of years, scientists have been trying to answer what things have an effect on people's emotions . How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don't know your emotions can be influenced by the weather as well. People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special "sunrooms" with artificial lights have been built. People can go there and get "sunlight" for an hour or two! The weather can also affect people's emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather. What can we infer from the passage?

[
"We feel good when we are in the bright cool weather.",
"We will be happy when we are caught in the rain.",
"All people in Norway and Sweden feel sad in winter.",

Fish have ears. Really. They're quite small and have no opening to the outside world carrying sound through the body. For the past seven years, Simon Thorrold, a university professor, has been examining fish ears, small round ear bones called otoliths. As fish grow, so do their otoliths. Each day, their otoliths gain a ring of calcium carbonate . By looking through a microscope and counting these rings, Thorrold can determine the exact age of a young fish. As a fish gets older, its otoliths no longer get daily rings. Instead, they get yearly rings, which can also be counted, giving information about the fish's age, just like the growth rings of a tree. Ring counting is nothing new to fish scientists. But Thorrold has turned to a new direction. They're examining the chemical elements of each otolith ring. The daily ring gives us the time, but chemistry tells us about the environment in which the fish swam on any given day. These elements tell us about the chemistry of the water that the fish was in. It also says something about water temperature, which determines how much of these elements will gather within each otolith ring. Thorrold can tell, for example, if a fish spent time in the open ocean before entering the less salty water of coastal areas. He can basically tell where fish are spending their time at any given stage of history. In the case of the Atlantic croaker, a popular saltwater food fish, Thorrold and his assistant have successfully followed the travelling of young fish from mid-ocean to the coast, a journey of many hundreds of miles. This is important to managers in the fish industry, who know nearly nothing about the track of the young fish for most food fish in the ocean. Eager to learn about his technology, fish scientists are now lending Thorrold their ears. How would you understand "fish scientists are now lending their ears"?

I'll never forget that summer day in 1965 when my mother suddenly died of an unexplained illness at the age of 36. Later that afternoon, a police officer stopped by to ask my father if the hospital could use Mother's corneas . I was shocked. "The doctors want to _ Mum and give her away to other people!" I thought as I ran into the house in tears. "How can you let them do that to her?" I screamed at my father. "My mum came into this world in one piece and that is how she should go out." "Linda," Father said quietly, putting his arm around me, "the greatest gift you can give is a part of yourself. Your mother and I decided long ago that if we can make a difference in just one person's life after we die, our death will have meaning." He went on to explain they had both decided to donate their organs . The lesson my father taught me that day became one of the most important in my life. Years passed. I married and had a family of my own. In 1980, my father became seriously ill and moved in with us. He cheerfully told me that when he died, he wanted me to donate his eyes. "Sight is one of the greatest gifts a person can give," he said. I told Wendy what her grandpa had said, and with tears in her eyes, she went into her grandpa's room and gave him a big hug. She was only fourteen years old------the same age at which I was introduced to such a thing. What a difference! My father died on April 11,1986, and we donated his eyes as he had wanted. Three days later, Wendy said, "Mum, I'm so proud of you for what did for Grandpa." At that moment, I realized that my father gave much more than his eyes. How was it for the writer to agree the hospital's use of her mother's corneas?

Last weekend, our family went to have Christmas dinner in a restaurant. We were the only family with a baby in the restaurant. Suddenly, my baby Erik became excited when we were enjoying our meal. I looked around and saw an old man with old clothes and dirty old shoes. His hair was unwashed. He was smiling at my Erik. "He might hurt my Erik," I thought. Everyone in the restaurant looked at us and the old man. Then we decided to leave. The old man sat between the door and us. As I walked closer to the man, I turned my back. Suddenly, Erik leaned over my arms, reaching with both arms in a baby's pick-me-up position . Before I could stop him, Erik had escaped from my arms to the man's. Soon the very old smelly man and my young baby developed a kind of friendship. Erik put his little hand on the man's face, and I saw the old man closed his eyes and tears running down his face. His aged hands held my baby so gently . A moment later, the old man opened his eyes, passed me my baby and said, "Thank you, Madam. You've given me the best Christmas gift." I cried, with my face burning hot. A child saw a soul , but a mother saw only a kind of clothes. The family decided to leave the restaurant because they _ .

Many homes have cameras to protect them from danger. The cameras can tell the owners if someone has entered. But the cameras do not know whether the person is a family member, a friend, a postman or a criminal . But a new camera made by a French company can recognize faces. It can tell parents at work that their children have returned from school, or that the mail has been sent to their home. It can also tell them if a stranger has entered their home. When family members enter a home, the smart camera "recognizes" them and sends information to the owner's phone. The owner can choose to see the video then or later. But if an unknown person enters a home, the camera will send a warning sound on the owner's phone. This is what happened recently to a smart home camera owner named Damien. He lives in Paris. "On a Friday I was at work, having a big monthly meeting when my phone moved. At first I told myself 'Oh, it must be a wrong warn,' but my phone was telling me there was a face that the camera did not recognize. Something was happening in my house!" "I saw a person I did not know with his shoes on, which is not allowed in my apartment . I watched it on the video. I felt quite surprised. I hurried back home as fast as possible and called the police on the way. Thanks to the smart camera, the criminal was caught soon," said Damien. The new smart camera is different from the ones in many homes because it can _ .

The temperature of the sun is over 5,000 degrees Fahrenheit at the surface, but it rises to perhaps more than 16 million degrees at the center. The sun is so much hotter than the earth that matter can exist only as a gas, except at the core. In the core of the sun, the pressures are so great against the gases that, despite the high temperature, there may be a small solid core. However, no one really knows, since the center of the sun can never be directly observed. Solar astronomers do know that the sun is divided into five layers or zones. Starting at the outside and going down into the sun, the zones are the corona, chromosphere, photosphere, convection zone and finally the core. The first three zones are regarded as the sun's atmosphere ends and the main body of the sun begins. The sun's outermost layer begins about 10,000 miles above the visible surface and goes outward for millions of miles. This is the only part of the sun that can be seen during an eclipse such as the one in February 1979. At any other time, the corona can be seen only when special instruments are used on cameras and telescopes to shut out the glare of the sun's rays. The corona is a brilliant, pearly white, filmy light, about as bright as the full moon. Its beautiful rays are a sensational sight during an eclipse. The corona's rays flash out in a brilliant fan that has wispy spikelike rays near the sun's north and south poles. The corona is thickest at the sun's equator. The corona rays are made up of gases streaming outward at tremendous speeds and reaching a temperature of more than 2 million degrees Fahrenheit. The rays of gas thin out as they reach the space around the planets. By the time the sun's corona rays reach the earth, they are weak and invisible. Matter on the sun can exist only in the form of gas because of the sun's _ .

We often don' t give importance to minor things thinking they won' t matter. But at times, some things look very minor but their result can be really powerful. Here are some of the efforts which can change the relationship between parents and children. Pat your child when he loses:May it be failure in the class, or on the field, speak words of encouragement to your child. The trust and confidence in your relationship will go to another level. After all, words of encouragement during failure are more valuable than words of praise after success. Give him importance, like a member of the family:Hang his painting in your room or in the office, take his opinion when you are buying furniture for the house. Your child will believe in himself and be a winner throughout. Share your own experience when your child makes a mistake:When you see your child lying or stealing, share with him the mistakes you made in your life. He' 11 know it is all right to make mistakes and that he can share with you anything. Appreciate at least one quality in your child every day:Each day look at what qualities your child possesses and appreciate him, maybe for his caring attitude, his dance skills or his observation power. Tell him how proud you are of him because of those qualities. Become his age before bedtime:Jump on the bed, have pillow fights, act silly, dance--become a child with your child for sometime. You' 11 forget all your day's stress. Try these minor things; you' 11 see the love deepen and the relationship blossom. The passage suggests the following things except _ .

Have you ever seen people dance? Some dances are fast and others are slow. People's feet always move when they dance. They keep on moving until the music stops. People have enjoyed dancing for a very long time. This story is of a different kind of dance. It is a dance without people or music. Yet this dance is one of the oldest in the world. It is the dance of bees. If you have ever watched bees, you know that they are very clever. They also work hard looking for food and bringing it back to their home. The home of the bees is called a bee hive. Here hundreds even thousand of bees live. They work day and night building small walls. There they make their honey. This is the same honey that we eat. Where does the honey come from? Bees live on food from flowers. Have you seen bees flying around a flower garden? When a bee rests on a flower, it tries to go to the centre of it. There it takes in as much food as its body can hold. Then it flies to take the food back to the hive. At the hive, bees change flower food into honey. Then they fly away for more food. How do the bees know where to find the best food in the sweetest flowers? One bee acts as a guide. When it discovers good flowers, it flies back to the hive and tells the others. It does this by dancing for them. The bee dances on one side. This tells the other bees which way to go to find the flowers. But that is not all. The bee dances for some time. And the length of its dance tells the other bees how far they must fly to reach the flowers. When the bees see the dance, they know where the flowers are. They fly away and return with more food for the hive. Sometimes we hear the music of the bees as they fly around. But few people have ever seen them dance. Yet without that dance we might never have sweet honey to eat. The writer believes that _ .

Have you ever heard your own voice? "Of course," you say. Has anyone else ever heard your voice? Again you say, "Of course." But that's not quite true. Nobody else has ever heard your voice-the way you hear it. When you talk, you set up sound waves. The air outside your head carries the sound waves to your outer ears. But, of course, the sound of your voice begins inside your head. The bones of your head pick up the sound waves, too. They carry the sound waves straight to your inner ears. You get the sound from the outside and the inside too. Other people get just the sound waves from the outside. That is why they don't hear your voice the way you do. You _ hear your voice the same way others hear it.

BEIJING(China Daily2010-8-27)---With a rapid increase in the number of Chinese PhD graduates programs in the past decade, it seems the quality of educating doctoral students is falling. About 70 percent of employers complain that employees who hold PhDs show little creation in their work performance, according a resent survey. The number of PhD students in China reached 246,300 in2009, about five times the figure in 1999. China replaced the United States to become the world's top producer of doctorate holders in 2008, according to an Asia Times report. "Nowadays, it is not rare for people in their 30s to become professors in Chinese universities, but I really doubt their experience and capability at such a young age," said Ge Daoshun, a professor at the Chinese Academy of Social Sciences. Almost half of the professors admitted each of them had to direct more than seven PhD candidates. Some 60 percent of PhD candidates admitted they have been given more than half of their professors' research projects. The relationship between PhD students and their teachers has become an employment, in other words, a "master-apprentice" relationship, since professors use their students as cheap labor to do research. "Chinese universities should reform the tutorial system and introduce more stricter requirements for people to get a PhD diploma to improve the quality of education," Ge told China Daily. However, Liu Xin, a 25-year-oldPhDcandidate at the University of Sussex in England, argued that a major reason China is producing low quality doctorates is that most of the candidates do not have a passion for academic research... "The best college students of China have seldom ended up in academic positions. Most of them want to work in either banking or foreign companies, which pay much better."

Michelle, a famous lady, has found that more than 25% students are too fat in her country. It is a very serious problem. So she starts a health program to deal with it. The health program is to reduce the amount of fat students today and in the future. The program will get families, schools, newspapers, magazines and TVs to join together and deal with the students' obesity so that students will be at a healthier weight. The program includes: Food stores should sell healthier foods. Schools should serve healthier meals with less fat and should also offer gym classes. The lady is trying to fight the students' obesity all over the country because it can cause illnesses and higher health cost. She wants the students to eat right, exercise more and control their weight. She also wants the students to understand it is important to have less sweet food, and drink water, milk and fresh juices, but not to choose cokes. At the same time she has also set a good example by planting a vegetable garden. She hopes that the garden will encourage more people to plant one, too. The health program is really helpful to the students today and in the future. As she says, we cannot always build the future for youth, but we can build our youth for the future.

In the old days, children were familiar with birth and death as part of life. Now this is perhaps the first generation of American youngsters who have never been close by during of the birth a baby and have never experienced the death of a family member. Nowadays when people grow old, we often send them to nursing homes. When they get sick, we send them to a hospital, where children are forbidden to visit terminally in patients-- even when those patients are their parents. This deprives the dying patient of family members during the last few days of his life and it deprives the children of an experience of death, which is an important learning experience. Some of my colleagues and I once interviewed and followed about 500 terminally in order to find out what they could teach us and how we could be of more benefit, not just to them but to the members of their families as well. We were most impressed by the fact that even those patients who were not told of their serious illness were quite aware of its potential outcome. It is important for family members, and doctors and nurses to understand these patients' communication in order to truly understand their needs, fears and fantasies . Most of our patients welcomed another human being with whom they could talk openly, honestly, and frankly about their trouble. Many of them shared with us their great need to be informed, to be kept up - to - date on their medical condition and to be told when the end was near. We found out that patients who had been dealt with openly and frankly were better able to cope with the coming of detach and finally to reach a true stage of acceptance before death. It may be concluded from the passage that _ .

Gateway Academy Pre-Sessional Courses Our pre-sessional courses are ideal for students who have a conditional place at a British university, but who need to achieve a certain level of English in order to be accepted. The course aims to provide students with the English language and study skills that they need in order to be successful at university or another academic establishment. It is important to note that completion of the course does not guarantee students' entrance into a university. It is necessary for students to show during the course that they have understood the information and skills that they have been taught, and can apply them to their work. Pre-sessional students at Gateway Academy will benefit from: * Small class sizes (no more than 10 students per class) * Twenty three hours of tuition per week * Individual support and tutorials * Regular guest lecturers * The use of the Academy's study and recreational facilities, including the Language Library, the computer suite, and the academy's sports facilities. * A varied social programme including evening entertainments and weekend excursions to popular tourist attractions and cities such as Stonehenge, Oxford and Stratford-on-Avon. The course offers an all-around approach to learning, and covers reading, writing, speaking and listening skills. During the course, students will receive instruction on important techniques such as summary-writing, analysing essay titles, organising writing, note-taking in lectures, giving seminars and making presentations. Students will gain experience in working both individually and in groups. As part of the course, all students will work towards a 5000-word project in their own field of study. Students will receive guidance from their tutors on how best to conduct research and write it up effectively. Students will also work towards a presentation on the same subject. There is no final examination. The attendance, successful completion of assignments and participation in class will be taken into account. Students will be given a full report on their progress at the end of the course. Students need to be aware that the course involves a great deal of coursework, which will require students to manage their time effectively. From the passage we can learn that _ .

Except for the sun, the moon looks like the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter is only 2,160 miles (3,389 km), or a little more than a quarter of the diameter of the earth. Once a month, or more exactly, once every 29.5 days, at the time we call "full moon," its whole _ looks bright. At other times only part of it appears bright, and we always find that this is the part which faces towards the sun, while the part racing away from the sun appears dark. People could make their pictures better if they kept this in mind -- only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It only throws back the light of the sun, like a huge mirror hung in the sky. Yet the dark part of the moon's surface is not ly black; generally it is just light enough for us to be able to see its outline, so that we speak of seeing "the old moon in the new moon's arms." The light by which we see the old moon does not come from the sun, but from the earth. We know well how the surface of the sea or of snow, or even of a wet road, may throw back uncomfortably much of the sun's light onto our faces. In the same way the surface of the whole earth throws back enough of the sun's light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark. By "saying the old moon in the new moon's arms", we mean a time when_.

Afraid that her son would be too tired, Ms. Wendy would sometimes tell the boy to skip school, but each time, Fabian would insist on going to school. "I don't like _ because when I return to school, I don't know what's going on," the 12-year-old boy explained. He suffers for SMA-a neuromuscular disease that leads to weakness in muscles-and gets around in a wheelchair. Fabian's determination to excel in his studies was evident when he was disappointed that he got a total score of 236 yesterday in his Primary School Leaving Examination. He was hoping for a score of at least 240, but his mother was full of pride. "I am happy with his results. He's very motivated," said Ms. Wendy. When Fabian was two months old, he was diagnosed with SMA. Ms. Wendy, who used to go to other homes to teach piano lessons, started teaching lessons at home so she could take care of her son. Fabian proved to be a fighter. Ms. Wendy said, " He would study every day on his own even though he was weak and his spine was already starting to curve quite badly." Fabian is also active in the Singapore Disability Sports Council, where he plays boccia , a ball sport for those who require a wheelchair due to physical disability. At just 133cm tall and weighing 14kg, he knows that he will have to rely on others all his life. "I'm afraid that when my parents grow older, they will not be able to carry me and that there will be nobody to carry me," said Fabian. "But for now, I feel lucky that I get to go out and do a lot of things that I thought I couldn't." His dreams aren't lofty either-all he want to be able to do is work and provide for his parents. "I just want to study hard so that I can be a businessman, like my dad." He is planning to apply to study at Victoria School. We can know from the text that Fabian _ .

There are many famous museums throughout the world where people can enjoy art. Washington, D.C. has the National Gallery of Art; Paris has the Luvre; London, the British Museum. Florida International University (FIU) in Miami also shows art for people to see. And it does so without building, or even a wall for its drawing and paintings. FIU has opened what it says is the first computer art museum in the United States. You don't have to visit the University to see the art. You just need a computer linked to a telephone. You can call the telephone number of a university computer and connect your own computer to it. All of the art is stored in the school computer. It is computer art, produced electronically by artists on their own computers. In only a few minutes, your computer can receive and copy all the pictures and drawings. Robert Shostak is direction of the new computer museum. He says he starts the museum because computer artists had no place to show their works. A computer artist can only record his pictures electronically and send the records to others to see on their computers. He can also put his pictures on paper. But to print good pictures on paper, the computer artist needs an expensive laser printer . Robert Shostak says the electronic museum is mostly for art or computer students at school and universities. Many of the pictures in the museum are made by students. Mr Shostake said the FIU museum will take computer art more fun for computer artists because more people can see it. He says artists enjoy their work much more if they have an audience. And the great number of home computers in America could mean a huge _ for the electronic museum. To see the art in FIU museum, you need _ .

A group that rescues wildlife has started to search for land and money to build a bird and wildlife hospital in San Francisco. "About 40 volunteers care for injured animals in their homes," founder Jamie Ray said. Ray presented her proposal to build a $2 million wildlife hospital and nature center to environment commissioners recently. "What we need is to be able to build a 100-foot-long flight aviary for hawks that are recovering and to have water pools for recovering water birds," Ray said. She hopes they will open by the end of 2010, and will be able to care for oiled birds after more than 50,000 gallons of fuel flowed into the Bay. "For any animal, whether it is oiled, injured or anything else, getting it immediate care is important to its survival," she said. Department employees drive as many as 350 injured animals every year to a wildlife hospital, according to Friedman. He said around 80 percent of those animals are birds. "It would be wonderful to have a wildlife rehabilitation center here in San Francisco," Friedman said. Ray's proposal includes aviaries as well as a nature education center and outdoor picnic area. She has suggested building the center at Lake Merced or in western Golden Gate Park. A parking lot, soccer field and storage area are presently being planned for construction at the Golden Gate Park site. Any changes to those plans would need to be _ by department commissioners. The Board of Supervisors is also in charge of those plans. What do we know about oiled birds?

The London 20120lympics are being praised as a sporting and logistical success,but the influence on economy is far less certain.Some London tourist attractions,businesses and hotels reported that their business actually fell during the Games.But as Olly Barratt reports from London,the overall UK economy is looking for long-term results. Showing an Olympic-sized party like this cost the UK almost l 5 billion dollars.But while spectators went to east London'S Olympic Park,central London has been much quieter than. normal. Arthur lRason,a central London stallholder,said,"Am I taking less? Yeah,I'm taking less.There'S no question about it." Restaurants were among businesses that reported lower takings than normal at this time of year.And one tourism trade association says a survey of its members found the Games had had a negative influence all over the UK.But during the recent recession ,British officials still insist the Games were worth it.Boris Johnson,Mayor of London said,"I think it'S been an amazing display of what you can do if you plan and you work for years and years on a project. And I think it's a great advertisement for British engineering and British industry." The government hopes the Games will be a great help to the British brand worldwide,and they are also an opportunity to sweet-talk potential investors from all over the world.And a fall in takings for some attractions should not have come as a surprise. Where is the London'S Olympic Park located?

There are many kinds of sales. For example, a "back-to-school sale" is held near the beginning of the school year. Parents like the lower prices of the clothes and school supplies for their children. A "midnight madness" event starts very late at night. An "early bird special" sale starts very early in the morning. This kind of sale is popular the day after Thanksgiving in November. A favorite sale among many people is the "buy one, get one free" sale. You buy one thing and get a second one without cost. When people see the word "free" in an advertisement they know they are getting a good deal. As a matter of fact, it is not the case. Another kind of sale is a "going out of business" sale. This is when a storeowner tries to sell all the goods in the store before closing the business permanently . Let us say the store sells floor coverings. The owner lowers the prices and puts up a sign that says: "Going out of business sale. All items MUST be sold by tomorrow." People who buy the floor coverings think they are getting a special deal because everything must be sold in a short period of time. Then, days later they see the store did not close permanently. And they see the same sign that claims the store is going out of business. Some business owners really do not end the business. They just want to earn more money. People also hold their own sales. They hold garage sales and yard sales outside their home. They sell things they no longer want. Groups such as religious centers or schools hold bake sales. They sell cakes, cookies and other baked goods to raise money. In America, you can always find a good sale, no matter the day or time of year. There is the Independence Day sale, Veteran's Day sale, clearance sale, sidewalk sale, red tag sale, white sale, blue light special, liquidation sale, half-off sale, warehouse sale, tent sale ... What's the purpose of some owners who do "going out of business" sale repeatedly?

A huge cloud of dust rose and an overpass disappeared. This was the scene in Zhuzhou,Hunan Province on May 17.Nine people were killed and 16 injured. Things were similar last year in the Sichuan earthquake. Thousands of people were buried in the ruins and lost their lives. What if we could have warned them? People are always _ to find a way of preventing buildings' collapse. Better materials and technology help,but they are not a solution. Just like humans,a building has its own life cycle from "birth" to "death".If we know when a building is going to collapse,we can repair it in advance or get out of it before it falls. Now,scientists at the University of Illinois have developed a material that turns red before it breaks. The invention could be used in things like climbing ropes or bridge supports. The research was led by Nancy Sottos,a professor at the university's Beckman Institute,and Douglas Davis,a graduate research assistant. The secret behind the colorchanging material is a type of molecule .A molecule is a group of atoms held together by chemical bonds. Imagine you and your friends standing in a circle,holding hands. Each person stands for one atom,your hands represent the bonds,and the entire circle represents a molecule. If one person lets go of his or her hands,the molecule changes color. The research team put the molecule into a soft material. When the researchers stretched the material,it turned bright red for a few seconds before it broke into two pieces. When they repeatedly stretched and relaxed the material,without breaking it,it only turned a little red. The major problem is that light can get rid of the red color. When the team shone bright light on the molecule,the broken bond was fixed,and the color disappeared. If the bright light keeps the red color from appearing,the material's warning system will be useless. Scientists still have a lot of work to do before the colorchanging molecules can be used outside the lab. Which of the following is a WRONG statement?
|
[
"Thousands of people died from the collapse of buildings in the Sichuan earthquake because they hadn't been warned.",
"There is no building that will never collapse.",

When first entered, Vanak Restaurant does not look like much of a restaurant, but once the pleasant smells of kabob hit the senses, you are incapable of calling it anything else. Owned by a local couple, this Persian restaurant has an inviting, homelike atmosphere that many restaurants lack. The space is small with only a few dining tables and nearly no decoration, but the environment is truly charming. Lying in a hardly noticeable street corner, the restaurant still attracts all customers, especially those experienced in the delights of Middle Eastern cooking. A common sight is that of old Persian men sitting in the corner talking loudly about world topics, watching news events on TV, drinking a black tea known as Persian chai, and reading local Persian newspapers all the while trying to finish off their plate piled with food. The variety of food at the restaurant is limited, but the amount of each dish is fairly large.Most of the meals can serve two people and are under $10, so not only is it affordable but practical as well. The food especially appeals to health-conscious eaters because each dish is very healthy, made with limited fat and oil and served straight off the grill . The main dish that the restaurant is popular for is its kabobs, which are different style of grilled meat. One delicious and extremely healthy dish is the Joojeh Kabob, which is made of grilled chicken pieces served with either rice or bread.Another great kabob is the Chelo Kabob, a kabob consisting of grilled beef. Although the restaurant is small, the atmosphere and the food is delicious.It is a place that should not be overlooked. The food of the restaurant _ .

Paperback: 264 pages Publisher:. Sams (March 29,2005) ISBN: 0672327627 Product Dimensions: 8.4x5.5x0.6 inches OVERVIEW This book offers straightforward practical answers when you need fast results. By working through each 10-minute lesson, you'll learn what you need to begin to use the PHP scripting language to make your websites interactive and dynamic. REVIEW When I first laid eyes on this book and its title, Teach Yourself PHP in 10 minutes, my first thought was that I was going to see this! So I opened it up and figured I'd look through it for ten minutes and see what would hit me. Well, 10 minutes turned into 20, 20 into 30 and 30 into a valuable resource that sits on my desk. Not only are the lessons within brief, but they are very easy to understand, well presented and very easy to understand for the beginner. Each lesson comes with tips to point out shortcuts, cautions to help you avoid common mistakes and notes to additional infomation. This book can be used in two ways, as a reference or as a complete tutorial on PHP basics. That alone is something that is very rare in teaching type books these days. Some of the more valuable and informative lessons will take you into the areas of: --Strings and variables --Processing HTML forms --Controlling and filtering data --User authentication --Cookies and sessions --Security practices --Configuring PHP and more!!! The book is pretty basic for experienced PHP coders, but for new or intermediate users this book is worth more than the small $19.99 CAN suggested price. Although the cover suggests it covers PHP 5.0, the coding found within also applies to PHP 4.X CONCLUSION This book completely surprised me with its value and does indeed teach you in ten minutes what other books claim to do in 24 hours. Full marks to author Chris Newman for this handy guide. What is the book about according to the passage?

American children are not the only couch potatoes with nearly one third of children globally spending 3 hours a day or more watching TV or on computers, according to the study of over 70,000 teens in 34 nations. From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children were not getting enough exercise and that it made no difference whether they live in a rich or a poor country. "With regards to physical levels, we didn't find much of a difference between rich and poor countries," Guthold said, "Growing up in a poor country doesn't necessarily mean kids get more physical activities." The researchers defined adequate physical activity as at least an hour of exercise outdoors for at least 5 days a week. Children spending 3 or more hours a day watching TV, playing computer games or chatting with friends were classified as sedentary. The researchers found only a quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30% of girls were sedentary and didn't get enough exercise with girls less active than boys in every country aside from Zambia. Girls from India were the most active with 37 percent meeting exercise recommendation, while girls from Egypt were the least active with 4 percent getting enough exercise. Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands. People show deep concern for kids' lack of physical activity in various nations. Why do they have a low level of physical activity? Guthold speculated that urbanization could be a factor as well as easy access to cars and TVs. All the following statements are wrong except _ .

The dollar is becoming weaker and weaker. What effects will it have? Look at the recordhigh price of oil. Even if the same amount of oil is being pumped out of the ground,since it is traded in dollars and the dollar has weakened,the price of oil has increased to make up for the lost value of the dollar,creating a sort of vicious cycle . Oilproducing countries don't want to keep all the dollars they are getting for their oil,since it's declining in value,so they exchange their dollars for euros or other currencies. That pushes more dollars back out into currency markets,which in turn pushes down the dollar's value. One expert told ABC News that Russia used to have 90 percent of its financial reserves in dollars. It now has 45 percent in dollars,45 percent in euros and 10 percent in British pounds. In the US itself,the news is mixed. It's good,because it makes what we produce here cheaper to sell in foreign markets,and that in turn spurs exports of our products around the world. That translates into more manufacturing and more jobs. But a weak dollar is bad,because it leads to inflation in this country. Imports from foreign countries will become more expensive,and in particular,oil will be more expensive. That puts pressure on businesses to increase prices for anything that uses oil or products that come from overseas. One benefit for American shoppers is that China has largely pegged its currency to ours,so that keeps the price of Chinesemade goods low and therefore,keeps a check on inflation. Which of the following would be the best title for this passage?

Exhausted and unhappy, you still have to squeeze a smile to your friends, or teachers. That's just life, you may think. But new research suggests that putting on a fake smile can worsen people's mood and even lower work efficiency. Lead researcher Brent Scott with other researchers studied a group of bus drivers for two weeks. They tried to find out what happened when the drivers were involved in "surface acting" or fake smiling, and the opposite, "deep acting" which means people put on real smiles by recalling pleasant memories or thinking about their current situation more positively. The results showed that on days when drivers were forced to smile, they felt depressed and didn't want to work. On days when they smiled due to positive thoughts, their mood improved a lot as well as their work efficiency. The research goes against the popular belief among companies that employees should be cheerful to customers at all times. They include employees of shops, banks, call center workers and others who have face-to-face contact with members of the public. "Smiling for the sake of smiling can lead to emotional exhaustion and coldness, and that's bad for the organization," Scott told the Daily Mail. The study also showed that women were harmed more by fake smiling than men. Their mood and work performance both worsened more. But they were helped more by deep acting -- their mood became better and they worked more efficiently. However, while deep acting seemed to improve mood in the short term, Scott says it's not a long-term solution for unhappiness. "There have been some suggestions that if you do this over a long period that you start to feel inauthentic ," Scott said. "You may be trying to cultivate positive emotions, but at the end of the day you may not feel like yourself anymore." The article is mainly about _ .

Christopher Thomas,27,was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes , Thomas would need to inject himself with insulin three times a day for the rest of his life or risk nerve damage, blindness and even death. And if that weren't bad enough, he had no health insurance. After a month of feeling upset, Thomas decided he' d better find a way to fight back. He left Canton,Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created diabeticrockstar..com, a free online community for diabetics and their loved ones-a place where over l,100people share personal stories, information and resources. Jason Swencki' s son, Kody, was diagnosed with diabetes at six. Father and son visit the online children' s forums together most evenings. " Kody gets so excited, writing to kids from all over," says Swencki, one of the site ' s volunteers." They know what he' s going through, so he doesn' t feel alone. " Kody is anything but alone; Diabetes is now the seventh leading cause of death in the United States, with 24 million, diagnosed cases. And more people are being diagnosed at younger ages. These days, Thomas' s main focus is his charity,Fight It, which provides medicines and supplies to people--225 to date-- who can' t afford a diabetic' s huge expenses. Fight-it. Org has raised about $ 23,000 -- in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean. Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables. " Of the diabetes charities out there, most are putting money into finding a cure, " says Bentley Gubar, one of Rockstar ' s original members. " But Christopher is the only person I know saying people need help now. " What can we learn about Fight It?

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?

Everyone may all have the experience of feeling anxious and stressed when having a rough day or having some troubles. Different people may choose different ways to deal with it, and for most people a break for a 10-minute walk may be quite useful.www.zxxk.com Anyway, here is another way around: to get a piece of chewing gum, and chew it. According to a Swinburne University of Technology study, gum-chewing has been found to "relieve anxiety, improve alertness and reduce stress among individuals in a laboratory setting." Some may argue that a laboratory is not the same as an office. But check out the conditions of the study: individuals were monitored while performing "a group of 'multi-tasking' activities." Doesn't it sound like the situation in the office?www.zxxk.com Here's a summary of some of the study's findings: Gum chewers showed a reduction in anxiety as compared to non-gum chewers by nearly 17 percent during mild stress and nearly 10 percent in appropriate stress. Gum chewers showed improvement in alertness over non-gum chewers by nearly 19 percent during mild stress and 8 percent in moderate stress. Improved Performance: Chewing gum resulted in a big improvement in overall performance on multi-tasking activities. Although these aren't major improvements, every little bit works and chewing a piece of gum is a lot quicker and easier than slipping outside for a 10-minute walk. So, how does gum work this magic? In part it does so by lowering the level of cortisol --a steroid hormone that is released in response to stress in your system. A few words of advice before you reach for the gum: don't crack your gum, and be sure to chew it with your mouth closed. In fact, I'd say keep the gum out of meetings, because it really looks impolite to others around you. How does gum work to reduce stress according to the text?

Chen Zhengshan has a special classmate, his 63-year-old grandma. His grandma began to look after him 10 years ago. Chen got a bad illness when he was three. His mother left the family. His father couldn't work. So his grandparents began to look after him. Chen had to take five kinds of medicine every day and it cost the family more than 1,200 yuan every month. Chen couldn't speak well. Some boys often laughed at him at school. He was very sad. In 2008, his grandma decided to go to school with him. She asked the school to let her do so, but the teachers didn't agree. In 2009, she made it,because the teachers were moved by her love. The teachers also asked students to help the boy and collected more than 600 yuan for him. The grandma planned to go to school with her grandson until he got well. She said,"My boy who likes playing the piano is as clever as the other children." ,. Why did Chen's grandma decide to go to school with him?

Researchers have found more evidence that suggests a relationship between races and rates of lung cancer among smokers. A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking. It compared their risk to whites, Japanese-Americans and Latinos. Researchers at the University of Southern California and the University of Hawaii did the new study. The New England Journal of Medicine published the findings. The eight-year research studied more than 180,000 people. They included present and former smokers and people who never smoked. Almost 2,000 people in the study developed lung cancer. Researchers say genetics might help explain the racial and ethnic differences. There could be differences in how people's bodies react to smoke. But environmental influences, including the way people smoke, could also make a difference. African-Americans and Latinos in the study are reported smoking the fewest cigarettes per day. Whites are the heaviest smokers. But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer. Scientists know that some diseases effect different groups differently. And some drug companies have begun to develop racially targeted medicines. Last June, the United States Food and Drug Administration approved a drug designed to treat heart failure in black patients. The name is BiDil. The agency called it "a step toward the promise of personalized medicine." Researchers agree that it is _ that may probably determine black people's risk of lung cancer.

For thousands of years humans have used herbs , roots, and other things from nature to cure disease. Scientists looking for new cures often visit traditional healers. They find out what plants are used in healing. Then they look at what the plant contains. They find the active ingredient , which is the chemical in the plant that works to heal. Many of the drugs we use, including aspirin, have come from these natural medicines. In recent years, many people in the US have taking what are legally known as dietary supplements . They may be vitamins or minerals. They may be herbs that help with health problems, such as depression. Some of them are teas. Others are capsules or tablets. They are sold in natural food stores, drug stores, and groceries. Most people think that because these products are natural they are also safe. This is not always true. There are many plants that are poisonous. There are others that have bad side effects. The New England Journal of Medicine publishes medical research. A recent edition called for the government to _ dietary supplements. Several doctors wrote to the Journal and told of bad experiences people have had with dietary supplements. Dietary supplements aren't tested in the same way as drugs. There is not always proof that the supplement really does what it is supposed to do. There is also a problem with purity of the supplements. Supplements have been found to contain things that are bad for the body. For example, the California Department of Health found that of 260 herbs grown in China, one third contained heavy metals. These are minerals such as lead and mercury . They are very poisonous, even in tiny amounts. Which one of the following is NOT right according to this passage?

People are talking about the "new economy." It's very different from the "old economy". In the old economy, people travel to walk. They buy things in stores. They use the post office, the fax and the telephone to send information. They see people face-to-face at their jobs or in stores. People get information from newspapers, radio, television, books and libraries. In the new economy, people do business through the "net," which is a connection of millions of computers everywhere in the world. In the new economy, workers often work at home. They can get information online. They can communicate with employers and co-workers by e-mail. Businesses have "virtual stores". They are websites on which customers can see the products. Businesses can sell to customers anywhere in the world. In the new economy, people live a fast paced, convenient and colorful life. The whole world develops more quickly than before. But the new economy is a double-edge sword. Its disadvantage is also obvious. For example, the Internet has led to a huge increase in credit card cheating. Some illegal websites offer some cheap or banned goods or services. Online shoppers who enter their credit card information may never receive the goods they want to buy and their card information could even be for sale in an illegal website. So people in the new economy should be smarter and knowledgeable. In the old economy, people can do the following things EXCEPT _ .

Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals. In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight? In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love. Passionate love is rooted in the reward circuitry of the brain--the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to a calmer attachment form of love one feels with a long term partner. What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what their overall weight is. (This ratio may indicate a woman's reproductive health.) Another piece of evidence comes from work by a psychologist at Ben-Gurion University, who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight. In other words, in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers. One might also assume that if a person is looking for a partner with _ that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships. Which of the following may be the best title of the passage?

New evidence shows that getting enough Vitamin D may be the most important thing you can do for your health. You know the usual prescription for good health: a balanced diet with lots of fruits and vegetables, regular exercise, no smoking.Now add this: Spend a little more time in the sun. Huh? That may sound like medical .After all, we've been warned for decades about the dangers of the sun: wrinkles, age spots and the increasing threat of skin cancer.But new and impressive medical evidence suggests that sunlight is beneficial.The vitamin D it our bodies to make may prevent cancer, protect against heart disease and ward off a long list of disorders such as multiple sclerosis, rheumatoid arthritis, diabetes and gum disease.It is even showing promise as a treatment for heart disease and some cancers. Long recognized as vitally important for bone building (it's needed for calcium absorption), vitamin D has now achieved superstar status among nutrients.While all doctors may not agree, many experts are confident enough of its wide-ranging powers to urge that we get much more of it, from the sun and from supplements, as even the best diet in the world may not give us enough. Which of the following is NOT the usual way of keeping healthy?

Pasta is the world's favorite food. A survey taken in 17 countries confirmed that pasta is what people like to eat most. Not only is pasta the number one food in its home country Italy, but it is also enjoyed in faraway places like the Philippines, Mexico and South Africa. Pasta has become popular, for one thing, because it is cheap and easy to prepare. Just cook noodles or other forms of pasta, make a sauce to go with it and you're finished. Many different types of meals can be created with pasta. It tastes good and fills your stomach. It produces energy in the form of carbohydrates , which is why athletes eat pasta regularly. Pasta can also be kept for a long time. You don't have to use it up at once. Pasta has also become popular because it stands for the Italian way of life. People all over the world like it because it's so simple. It has two basic ingredients, wheat and water, just like bread. Before it became popular in Italy during the 19th century, earlier civilizations also ate pasta. Legend has it that Marco Polo brought pasta back to Italy with him but this is not true. Arabs probably brought a noodle-like dish to Sicily in the 8th century. Farmers have been growing wheat, the main ingredient of pasta, there for ages. The worldwide sales of pasta have risen sharply over the past decade. $16 billion worth of pasta were sold in 2010, compared to $13 billion worth of the favorite food in 2003. Italy leads the pasta-eating community of the world. The Italians are the number one consumers followed by Venezuela and Tunisia. ks5u One reason why pasta is favored is that _ .

In the digital age, getting students into classrooms is an increasingly challenging mission for college and university teachers, not to mention retaining their attention. "It's much harder to teach the post-90s,,,said Chen Jixiu , a math professor at Fudan University. "They use smart-phones and tablets to search for information, even during class. They get knowledge from a variety of sources, and consider it 'a small cake ,to skip classes. " According to Chen, this situation has forced teachers to adopt "odd tricks" for attracting students to class. Here are some interesting ideas picked up by 21st Century. Food for Thought: Rather than providing only moral encouragement, teachers at Wuhan University are offering real-life related rewards to improve student attendance. Students sitting in the first row of the health psychology course taught by professor Lei Wuming are rewarded with snacks. "I've got 7,000 fans on my micro-blog ,and most of them are my students,"said Lei ,director of the university's Education Institution. "I do want to express my thanks to those coming to listen, and to make the class more lively. " Teacher vs Phone; In the broadcasting and hosting course of Hankou University, teacher Huang Huiqiong gives students permission to busy themselves with their cell phones during class. They keep their heads down until they hear something interesting. If not, they can sit through the entire class without being disturbed and even give the teacher advice following the class. "A teacher is not the boss and students have the right to make content suggestions,,,said Huang. Friendly Blogs: You might hesitate to participate in class discussions, but what if you could send a message instead of speaking out loud? In the computer science course at Changsha University of Science Technology (CUST),students can voice opinions via their cell phone. "I open a micro-blog webpage,and when students text a message to the account, it appears on the screen,,,said teacher Huang Qiang. Su Ying, 19,a sophomore at CUST, said: "I feel relaxed as I don't like standing up and getting everybody's attention. " How does Lei Wuming improve his students' attendance?

Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few obvious benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked. Perhaps the best answer lies in our genetic makeup as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible. Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects. Exploration also allows minerals and other potential resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions . Knowledge or techniques have been gained through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products of technological developments in the space industry! While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exist. While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future. What makes it possible for humans to live on other planets?
