AIDS' Threat to Asia Grows NEW DELHI----Just a few years ago, Mala was a typical middle-class Indian housewife. She cooked, cleaned and looked after her two small children. Last year, her life took a tragic turn. Her husband died of AIDS; she was found out HIV-positive and her mother-in-law took her children away from her, saying they would get the disease. "When friends dropped for a visit, she would introduce me, saying, 'She is my son's widow. She has AIDS,'" said Mala. AIDS is now described as "explosive " around the world. A study of a hospital in the port city of Durban in South Africa, where the world's biggest and Africa's second AIDS conference opened last Sunday, found that almost half the beds in medical wards were occupied by AIDS patients. South Africa has one of the world's fastest growing HIV infections, with 1,700 people infected daily, adding to the 4.3 million, or 10 percent of its population, living with HIV. Until now, Asia has been more successful in holding the AIDS virus than Africa, where the disease has killed about 12 million people. AIDS is now threatening to surround many of Asia's poverty-stricken countries. Countries in Asia, such as Cambodia, and Thailand, have HIV infection speeds over 1 percent. But the low speeds hide huge numbers of infected people, because of the population base. In India, for example, 3.7 million are infected, more than in any other country except South Africa. In China, an estimated 860,000 people (the actual number may be a little larger), mainly drug users, live with HIV/AIDS. Gordon Alexander, a senior advisor for UN AIDS in India, estimates that the number hit by AIDS in Asia will climb about eight million over the next five years from about six million. In many Asian countries, the battle against HIV is a social and cultural one against public discussion of sexual health put a nationwide media campaign into action to limit the speed of HIV through unsafe sex. Brenton Wong, an official for Singapore's Action for AIDS, _ . "Shame and deny is still very, very common so people are afraid to get tested and many times won't even tell their families if they test positive," said Wong. Which of the following statements is not right?
|
[
"The battle against Aids in many Asian countries is against their culture and social customs.",
"Though the HIV infection in Asia develops with low speed, the infected number is still quite large compared to other continents.",
"India has the second largest number of HIV infected people.",
"Aids might affect the poverty-stricken countries more severely."

Every so often, birds, just like humans, do what it takes to feel really, really good. The bird version is to sit on an anthill so that hundreds of ants climb all over their bodies, or even better, some birds pick up mouthfuls of pressed ants and rub themselves all over. Afterwards, the birds either eat the ants or set them free. Scientists call this "anting." It's a common bird practice, and is especially done by the smarter birds. Ravens do it. Magpies do it. However, birds aren't the only animals that use anting --- squirrels, cats, and hedgehogs have all been observed doing the same sort of thing! Why birds "ant" is something of a mystery, but one thought is acceptable. Ants have defensive secretions , chemical weapons they use to fight off other insects and bacteria. So pressed ants help the birds drive the insects away. Similarly, if you cover your body with them, you can move through the forest without worrying about being bitten by insects. Plus, ants are cheap. They are around. However, we have a better explanation. Birds "ant" a lot in spring and summer. For many birds, that's the season for birds to change feathers. So maybe ant secretions are like bath oil; they comfort the skin during feather replacement. A British scientist once declared "the purpose of anting the stimulation and comfort of the body," and that the general effect "is similar to that gained by man from the use of outside stimulants, and perhaps also smoking." And like cigarettes, anting can become a habit. Another study compares anting to "the human habits of smoking and drug taking," and says, "it is enjoyed for the feeling of excitement it results in. So once experienced, it is difficult to stop." That's why you often see mother birds shouting at their babies who come near their first anthill. "Stay away from there, child... Don't touch those ants!" they cry. I don't speak Raven. Or Magpie. But I have been a parent. So some things I know. Some birds ant because ant's secretions _ .

Melissa and Roman McCoy were looking forward to the Christmas. But on December 5th, Roman got a phone call that changed everything. Melissa had been in a terrible car accident, and the doctor had little hope she would make it. "He said the next six to eight hours were critical in determining whether she would live or not. And I just wept," Roman said. "A lot of pressure built up inside, and I just dropped my cell phone on the ground when I heard that. It was the worst feeling that I've ever felt." Melissa, a college English professor, was on her way to class when her car hit into a mound of dirt and rolled over several times. Roman recalled, "I could only think how I am going to raise my kids without their mother. If she did live, how would I take care of her and my kids? The questions you never want to ask yourself, I had to face." Melissa survived the first night. She had injuries to her stomach and lungs and worse, she suffered severe injuries to her brain. She didn't recognize anyone, even her own husband. "Over the next few days, she remained unresponsive to treatments. The brain surgeon never really gave us much hope." Days passed and Melissa didn't improve. Christmas Eve, Roman was by her side in the hospital. Then, he received a Christmas gift he would never forget. "That evening, she woke up and was just as clear as before, recognized everybody, and was able to read. It was just amazing. I saw her bright smile and her sense of humor. The only way I could describe it is that the weight of the darkness that had hovered over me was just completely gone." Melissa quickly improved, and she is back to being a wife, mom, and professor. There is no sign of damage from the brain. Melissa said, "I thank him for everything now. It's not just 'thank you for my job, thank you for my children.' It's 'thank you for every aspect of my life.'" The worst injuries that Melissa had were to her .

. As the world's largest terrestrial carnivore ,the polar bear is the king of the great white north. Adult males can measure more than 9 feet in length and weigh between 770 and 1,430 pounds. The bear's body and neck are elongated, and the head is narrow and long with small, rounded ears. Polar bear populations can be found in northern Canada, Greenland, Norway and Russia, and there have been reports that polar bear tracks have been found as far north as the North Pole. The 5,000,000-square-mile range of the polar bear circles the Arctic and contains stretches of open water where seals are easily caught. Polar bears live on the annual Arctic sea ice that provides a platform from which they can hunt. They hunt seals on the sea ice by breaking into seal dens in the sea ice. The dens aren't visible from above,but seeing is less important than smelling to a polar bear -- with their keen sense of smell,polar bears can sense the breathing holes of seals in their dens beneath the snow and ice. As the southern edge of the Arctic ice cap melts in summer, polar bears are stranded on land and spend their summers fasting ,living off body fat stored from hunting in spring and winter. It might come as a surprise that this species faces an uncertain future. Climate change is causing the disappearance of sea ice from which polar bears hunt seals. Sea ice in the Arctic is melting earlier and forming later each year. With about 22,000 polar bears living in the wild,the species is not endangered at the moment, but its future is far from certain. People have reached an agreement that controls the hunting of polar bears and directs each nation to protect their habitats, but it does not protect the bears against the biggest man-made threat to their survival : global warming. If current warming trends continue, scientists believe that polar bears may disappear within 100 years. What is the key reason for polar bears' dying out?

Janet walked past the barn, the big tree, and through the back yard to reach the chicken pen. Janet gathered the eggs from the chicken pen, so that her father could make scrambled eggs for breakfast. He would need at least 5 eggs for the meal, two for Janet and three for himself. Janet could only find four eggs in the chicken pen. She looked under every chicken, and in every nest, but could not find another egg. She placed the four eggs in her basket, and began to walk toward the house, when she heard a quacking sound. She went toward the sound and found a nest near the pond, with large brown eggs inside. "Quack" said a nearby duck, as Janet took an egg from the nest. Now she had enough for breakfast. How many eggs did Janet's father need to cook breakfast?

For the last couple of weeks, I had been stuck in front of my computer working on a project that was very important to me. My every waking hour was consumed by the project and although I imagined that I would feel happy after completing parts of the project, I was confused to find that instead, I was feeling rather depressed. I tried a range of methods to help cheer myself up. I had a relaxing bath, cooked a delicious meal to enjoy with my family and even watched a lighthearted movie, but _ . It was only when I turned to meditation for a solution that the answer came to me: turn to nature! The very next day, I grabbed my camera and a bottle of water and set off to spend a few hours walking in a nature reserve, even though it was pouring with rain. Within a couple of minutes I felt alive again. To be honest, I felt like a young school girl again and had to stop myself from hopping along the path singing, "I'm singing in the rain", a song I used to sing when I was a child. I think as adults we often try too hard to control our inner children and as a result we restrain our own spirits, which only leads to depression and stress. Interestingly, it has been shown that people who spend 40 minutes walking in a nature reserve have a drop in their blood pressure levels, but this does not happen when they spend a similar amount of time walking in a busy city centre. If you feel a little low in spirit and know that you have spent too much time indoors, relax completely, remove your shoes and let your inner child come out and play.

As a boy, Charles Robert Darwin collected anything that caught his interest: insects, coins and interesting stones. He was not very clever, but Darwin was good at doing the things that interested him. His father was a doctor, so Darwin was sent to Edinburgh to study medicine, and was planned to follow a medical career. But Charles found the lectures boring. Then his father sent him to Cambridge University to study to be a priest. While at Cambridge, Darwin's interest in zoology and geography grew. Later he got a letter from Robert FitzRoy who was planning to make a voyage around the world on a ship, the Beagle. He wanted a naturalist to join the ship, and Darwin was recommended . That voyage was the start of Darwin's great life. As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He began to observe everything. After he was home, he set to work, getting his collection in order. His first great work The Zoology of the Beagle was well received, but he was slow to make public his ideas on the origin of life. Later Darwin and Wallace, another naturalist who had the same opinions as Darwin, produced a paper together. Darwin's great book, On the Origin of Species by Means of Natural Selection (<<>> ) appeared. It attracted a storm. People thought that Darwin was saying they were descended from monkeys. What a shameful idea! Although most scientists agreed that Darwin was right, the Church was still so strong that Darwin never received any honors for his work. Afterwards, he published another great work, The Descent of Man. His health grew worse, but he still worked. "When I have to give up observation, I shall die," he said. He was still working on 17, April, 1882. He was dead two days later. Darwin's father sent him to Edinburgh to _ .

If you look at the sky one night and see something moving and shining that you have never seen before, it might be a comet . A comet sometimes looks like a star. Like a planet, a comet has no light of its own. It shines from the sunlight it reflects . Like the earth a comet goes around the sun, but on a much longer path than the earth travels. If a comet isn't a star, what is it then? Some scientists think that a large part of a comet is water frozen into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock. When sunshine melts the ice in the comet, great clouds of gas go trailing after it. These clouds, together with the dust, form a long tail. Many people have seen a comet. However, no one knows how many comets there are. There may be millions of comets, but only a few come close enough for us to see. An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky. Some comets move out of our sight and never come back. Others keep coming back at regular times. A big comet that keeps coming back was named after Halley comet, because the last time it came close to the sun and the earth was in the year 1986. Then people all over the world were outside at night to look at it. You will probably be able to see Halley's comet when it comes near the earth again. ,A, B, C, D,. Many people.

Want to live longer? Win an Oscar. A new study says that actors who received the award earn more than larger paychecks. So when 94-year-old Katharine Hepburn once remarked that she was respected internationally "like an old building", she had no idea that her four Oscars directly influenced her longevity . The study says winning actors will live 3.9 years longer than their losing counterparts . Actors who have won more than once, like Hepburn, live up to six years longer than those who were nominated but never won. "We found that they died from the same things we all die from--cancer, heart disease, but they fought them a bit longer and diseases came a bit later," says Dr. Donald Redelmeier, the leading author of the study. Redelmeier says the sense of success and satisfaction makes one's soul become more full of life. "We are not saying that you will live longer if you win an Oscar," explains Redelmeier, "or that people should go out and take acting courses. Our main conclusion is simply that social factors are important." The study's implied conclusion, he says, is that doctors should ask about their patients' personal feelings because mental well-being is related to physical health. Redelmeier says he got the idea for the study when he watched a glowing Gwyneth Paltrow win an Oscar in 1999 for her role in Shakespeare in Love. Redelmeier says, "She looked more full of life than anyone I had seen." "We found, too, those that had multi-nominations and no win had the same life expectancy as those with just a single nomination and no win," Redelmeier adds. Tom had five Oscar nominations but win no Oscar and Peter had only one nomination and won no Oscar either. We can tell _ .

Running a marathon Have you ever taken part in a marathon? A marathon is 42km long. It is the longest race in the world. To make the runner's body work, harder training is quite necessary. A runner should start to prepare for a marathon at least three months before. Preparation may have races, many hours of running at different speeds and changes in diet . During the training time the runner must eat a fit diet. The diet should have lots of things needed in training the players. In the early days of training, runners run 80km per week. The running is increased every two or three weeks and at least two long runs per week are needed. Two weeks before the marathon, the training programme becomes less, from 100km per week down to 60km and then to 30km in the final week. On the last two days they may not run at all. Breakfast should be eaten at least three hours before the race. Easily digested food such as cereal , toast and scrambled egg is best, with as much fluid as possible. Runners should drink water about half an hour before the race to keep up the body fluid. Players must have _ in order to run better in a marathon.

Doctors sometimes prescribe light therapy to treat a form of depression in people who get too little morning sun. But too much light at other times may actually cause such mood disorders. Long-lasting exposure to light at night brings depression, a new study finds, at least in animals. The new data confirm observations from studies of people who work night shifts, says Richard Stevens of the University of Connecticut Health Center. Mood disorders join a growing list of problems, including cancer, obesity and diabetes--that can occur when light throws life out of balance by disturbing the biological clock and its timing of daily rhythms. www.ks5u.com In the new study, Tracy Bedrosian and Randy Nelson of Ohio State University exposed mice to normal light and dark cycles for four weeks. For the next four weeks, half of the mice remained on this schedule, and the rest received continuous dim light throughout their night. Compared with mice exposed to normal nighttime darkness, those getting dim light at night lost their strong preference for sweet drinks, "a sign they no longer get pleasure out of activities they once enjoyed, " Bedrosian says. In a second test, mice were clocked on how long they actively tried to escape a pool of water. Those exposed to night lights stopped struggling and just floated in the water, a sign of "behavioral despair",10 times as long as the mice that had experienced normal nighttime darkness. All symptoms of depression disappeared within two weeks of the mice returning to a normal light-dark cycle, the researchers report. The scientists also could quash the behavioral symptoms by injecting the brains of animals with a drug that prohibits the activity of certain molecules linked with human depression. This finding further suggests that light at night may cause something related to depression. Human studies linking nighttime light and mood disorders are important but can't easily detect molecular underpinnings as animal studies can,says George Brainard of Thomas Jefferson University. The new work, he says, suggests that the change of the biological clock by light at night can be "an extremely powerful force in regulating biology and behavior. " What is the main idea of the passage?

Venus is known as the Earth' "twin" because the planets are so like each other in size. The diameter of Venus is about 7,520 miles (12,100km), about 400 miles (644km) smaller than that of the earth. No other planet comes closer to the earth than Venus. At its nearest approach it is about 25,000,000 miles (402,000,000km) away. As seen from the earth, Venus is the first planet or star that can be seen in the western sky in the evening. At other times, it is the last planet or star that can be seen in the eastern sky in the morning. When Venus is near its brightest point, it can be seen in the daylight. Early astronomers called the object that appeared in the evening Hesperus, and Phosphorus in the morning. Later they realized these two objects were the same planet. They named it Venus in honor of the Roman goddess of love and beauty. The passage shows that _ .

Man has been to the moon. It has been the first step towards future exploration in space. When compared with the distances between Earth and the other planets, the distance between the Moon and Earth is very short indeed. Mars, the nearest planet to Earth is millions of miles away! Traveling to the planets will be man's next step. Such travels will be more challenging than the trip to the moon and certainly more exciting and dangerous. Recently, two American spaceships, Viking 1 and 2, landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither been confirmed nor ruled out . Russians have discovered that the surface of Venus is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense and the pressure is nearly a hundred times greater than that of the Earth's atmosphere. Scientists believe man may find planets which have the same conditions as those we have on Earth, but man should realize Earth will be his only home for a long time and begin to love and care for it. Based on the passage, traveling to the planets will be _ .

Preventing obesity and smoking can save lives, but it doesn't save money, reported researchers. "It was a small surprise, for it is against the common belief," said Pieter Van Baal, who led the study. "But it makes sense. If you live longer, then you cost the health system more." The researchers found that from age 20 to 56, obese people racked up the most expensive health costs. But on average, healthy people lived 84 years. Smokers lived about 77 years, and obese people lived about 80 years. Smokers and obese people tended to have more heart disease than healthy people. Therefore in the long run, the thin and healthy group cost about $417, 000, from age 20 on. Smokers cost about $326, 000 and obese people $371, 000. "The result throws a bucket of cold water onto the idea, based on guesswork, that obesity is going to cost trillions of dollars," said Patrick Basham, a professor of health politics. "If we're going to worry about the future of obesity, we should stop worrying about its financial impact," he said. "The benefits of obesity prevention may not be seen immediately in terms of cost saving in tomorrow's budget, but there are long-term gains," said Van Baal. "These are often immeasurable when it comes to people living longer and healthier lives." In the meanwhile, he said that governments should recognize that successful smoking and obesity prevention programs mean that people will have a longer chance of dying of something more expensive later in life. "Lung cancer is a cheap disease to treat because people don't survive very long. But if they are old enough to get Alzheimer's one day, they may survive longer and cost more. We are not advising that governments stop trying to prevent obesity," Van Baal said. "But they should do it for the right reasons." According to the text, governments prevent obesity for the purpose of _ .

Years ago, as we know, zoos kept animals in cages. Cages made it easy for visitors to see the animals, but a small cage is not a good place for an animal to live in. Today animals live in open areas. There are usually plants and a little lake around, like the animals' habitats. Visitors usually stay in the bus to see the animals outside. Zoos help to protect all kinds of animals. They protect animals in the zoo as well as animals in the wild. How do they do this? Zoos tell people how animals live in the wild and how to help protect their environment. The number of many kinds of plants and animals is becoming smaller and smaller. Mammoths, which are related with Asia elephants, are now extinct(.Scientists say that 74 different kinds of living things are disappearing a day!

Since many of you are planning to study at a college or university in this country, you may be curious to know what you usually do in a typical week, how you can get along with your fellow students, and so on. These are the questions I want to discuss with you today. First, let's talk about what your weekly schedule will look like. No matter what your major may be, you can expect to spend between four and six hours a week for each class attending lectures. Lectures are usually in very large rooms because some courses such as introduction to sociology or economics often have as many as two or three hundred students, especially at large universities. In lectures, it's very important for you to take notes on what the professor says because the information a lecture is often different from the information in your textbooks. Also, you can expect to have exam questions based on the lectures. So it isn't enough to just read your textbooks; you have to attend lectures as well. In a typical week you will also have a couple of hours of discussion for every class you take. The discussion section is a small group meeting usually with fewer than thirty students where you can ask questions about the lectures, the reading, and the homework. In large universities, graduate students, called teaching assistants, usually direct discussion sections. If your major is chemistry, or physics, or another science, you'll also have to spend several hours a week in the lab, or laboratory, doing experiments. This means that science majors spend more time in the classroom than non science majors do. On the other hand, people who major in subjects like literature or history usually have to read and write more than science majors do. According to the author, science majors _ .

Four Simple Keys to Transform Your Life The Power of Choice.Every one of us makes countless choices every day.Every choice we make has an impact on our lives.Even insignificant choices can affect what we experience and how we feel.When hunger strikes, we can reach for a healthy, nutritious snack, or we can choose the sugar high of junk food.The more important the decision, the greater its effect.For instance, how do I act towards that person who treated me badly? Do I generally choose to be passive, or do I actively set clear intentions and create what I want in my life? Every choice we make, however big or small, affects us in some way. How Do You Make Choices? If you are interested in living a richer, fuller life, there is a foundation upon which you can base all of your decisions which can make life better not only for you, but also for those around you.This foundation is to choose based on what's best for all.Imagine a world where every parent, spouse , friend, teacher, business person, and politician truly did their best to choose what's best for all involved in every decision they made. We would certainly live in a more caring, supportive world. It's the Intention."But how do I know what is really best?" you might ask.The answer is simple.It doesn't matter.What matters is not the choice you make, but rather the intention beind your choice.What matters is that whatever decision you make, you are clear in your intention of choosing based on what's best for all.If it later turns out that you made what appears to have been a bad choice, there's no need for guilt.Knowing that you did your best to choose with a sincere desire for what's best for all, your conscience stays clear and open.This then allows you to more easily learn from your mistakes, and to live with a clear heart and mind. What's Best for Me, Too! Choosing what's best does not mean you have to always sacrifice yourself for others.An overly exhausted mother can lose her temper easily.Some time off for this mother might seem selfish, yet in the long run, it can help her to be a better mother to her children.So as we move through each day of our lives, let us remember to include ourselves as we do our best to choose what's best for all. How should we make choices?

Cell phone use and texting are increasingly common, especially among teens. And that could be a problem. Texting affects learning and performing on test, a new study finds. So a Montana teen, Colin decided to test that. They asked 47 classmates to take part in a two-part experiment. The goal was to test how well these students understood written material. Each one had to read a paragraph or two about a certain topic, then answer questions about it. In the first part, the participants had 15 minutes to understand and then answer questions about six readings. Throughout this test, they met no distractions. During a new set of readings, the brothers sent messages to the participants' cell phones every 90 seconds. In each message, there were questions that required a reply. Participants should have scored better on the second test because it was easier. In fact, they scored worse when distracted by messages. Only a few students scored as well when replying to messages as they did when undistracted. But importantly, nobody performed better during the texting part. The brothers presented details of their findings at the Intel International Science and Engineering Fair. Boys and girls scored equally poorly while texting, the brothers noticed. Older participants didn't do any better than younger ones. And it didn't matter if a student thought he was good at multitasking. On average, the brothers found that even students who were confident of their abilities did just as poorly while texting. Surprisingly, even though the students remembered less of what they read while texting, most of them answered questions in messages perfectly. "Our teachers are very happy to see these results," says Coler. The teens' new data strongly support their teachers' opinion that texting while studying is a serious distraction. The brothers' findings were related to participants' _ .

I was fairly new to this particular school since my parents only moved to the area. There was a boy, who, as it turned out, was an orphan and was living and working for a small farming family. He didn't appear at first glance to ever be fully engaged in the school learning process;he would sit quietly, never seem to get any attention from the teacher, and would spend a lot of time staring out of the window just behind him. Over the next few weeks, I got to know this boy while playing outside in the schoolyard playing baseball, or soccer. He was very athletic and very good at anything we played. I started to wonder why he didn't seem to do well in school and why the teacher ignored him. He told me he had been in several foster homes since he was a little boy and that most of his time in the last few years had always been on farms. He said he was made to work before he went to school and as soon as he got home until it was time for bed. He was never given a chance to go out and play, nor was he allowed to have any friends although he told me he really didn't have any friends anyway, because he was an orphan and they did not want anything to do with him. I had never before been acquainted with prejudice of any kind. Here was one characteristic of a human being who through no fault of his own carried a label that prevented him from even having friends as a child. His potential was also being ignored by the teacher. It wasn't that he couldn't learn, or didn't want to -- it was because he wasn't encouraged or in some cases, allowed to. We may all meet people through the years that we tend to apply labels to without really taking the time to get to know them, to discover their real potential because our vision is clouded by how we always put people into _ that we are used to or comfortable with. What was the first impression that the boy gave the author?

Too much TV-watching can harm children's ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children. One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs. A second study ,looking at nearly 1000 grown-ups in New Zealand, found lower education levels among 26-year -olds who had watched lots of TV during childhood. But the results don't prove that TV is the cause and don't rule out that already poorly motivated youngsters may watch lots of TV. Their study measured the TV habits of 26-year-olds between ages5 and 15. These with college degrees had watched an average of less than two hours of TV per week night during childhood, compared with an average of more than 2 1/2 hours for those who had no education beyond high school. In the California study, children with TVs in their rooms but no computer at home scored the lowest while those with no bedroom TV but who had home computers scored the highest. While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn't have TVs in their bedrooms What is the researchers' understanding of the New Zealand study results?

"Poorly motivated 26-year-olds watch more TV.",
"Habits of TV watching reduce learning interest.",

New York City was dealing with a growing public health threat Sunday after tests confirmed that eight students at a private Catholic high school had contracted the same strain( type ) of the swine flu that has ravaged Mexico. Some of the school's students had visited Cancun on a spring break trip two weeks ago. Officials reported 68 U.S. cases of swine flu in five states so far, with the latest in Ohio and New York. Unlike in Mexico, cases in the United State have been mild and U.S. health authorities can't yet explain why. In New York City, Centers for Disease Control and Prevention confirmed that there were 45 cases, Mayor Michael Bloomberg said. About 100 students at St. Francis Preparatory School complained of flu-like symptoms; further tests will determine how many of those cases are swine flu. St. Francis is the largest private Catholic high school in the nation, with 2,700 students. The school canceled classes on Monday and Tuesday in response to the outbreak. Bloomberg stressed that the New York cases were mild and many are recovering, but said that some family members of students also had flu symptoms. In Mexico, health officials say a strain of swine flu has killed up to 160 people and sickened over 2,000. New York officials said the flu strain discovered in the patients here is the same strain as in Mexico, though all the New York cases are mild. Swine flu is a respiratory disease of pigs caused by type A flu viruses. Human cases are uncommon but can occur in people who are around pigs. It also can be spread from person to person. Symptoms include a high fever, body aches, coughing, sore throat and respiratory congestion . Compared with cases in the U.S., cases in Mexico are _ .

As we know, many teen celebrities feel and think that having a slimmer figure can do great good to them. But, does size really matter? Are teenage fans trying hard to become like their celebrity idols ? Do celebrities really have the power to influence people, especially teenagers? For the longest time, many parents blame teen idols for influencing the way their kids act. Have you noticed how teens idolize the celebrities these days? Even, their personal affairs are being followed by kids these days. Take for example the case of Lindsay Lohan of Mary Kate Ashley. They are definitely famous teen stars. But, since they are trying to project an image to satisfy a lot of people in show business, their health and body suffer. Many kids are aware of this problem. But they are easily influenced by these celebrities to exercise and eat less. It is a fact that the media, and especially famous teen celebrities, can influence people powerfully. But teenagers are easily influenced because teenage years are the period when our personality and identity developments take place. Teens watching TV shows and reading magazines are easily pulled into the dieting and harmful eating habits because the media have some ways to pull these acts. They use thin models and celebrities to endorse products or to star in an up-and -coming shows or movies. With fierce competition, celebrities are forced to eat less and do extreme exercise routines to get the roles or offers that come their way. Living in today's time and generation is a bit disturbing to a lot of parents. Media, especially as well as the celebrities, have a very powerful influence to drive teenagers to good or bad. It's good that we can control ourselves to avoid bad things from happening. If not, parents should really be aware and guide their teens to determine what's in ad what's out. Many celebrities have to be on diet _ .

Some plants get so hungry they eat flies, and even small frogs. What's more amazing is that these plants occur naturally (in special environments) in every state. In fact, they're found on every continent except Antarctica. You've probably seen a Venus' flytrap -- a small plant, which grows 6 to 8 inches tall in a container. At the end of its stalks are leaves that act like traps . Inside each trap is a lining of tiny hairs. When an insect lands on them, the traps suddenly shut. Over the course of a week or so, the plant feeds on its catch. The Venus' flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Society's Newsletter. He states although you might have read some science-fiction stories, no meat-eating plant does any danger to humans. Barry says a plant is meat-eating, only if it does all four of the following: "attract, kill, digest, and absorb" some form of insects. Meat-eating plants look and act like other green plants -- well, most of the time. All green plants make sugar to produce food. What makes meat-eating plants different is their special leaves, which need insects for one reason: nitrogen . Nitrogen is a nutrient that they can't obtain any other way. Why? Almost all green plants on our planet get nitrogen from the soil. Meat-eating plants can't. They live in places where nutrients are hard to get from the soil because of its acidity. So they've come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soft is poisonous to meat-eating plants. Never fertilize them! But don't worry, either, if they never seem to catch any insects. They can survive, but they'll grow very slowly. Which of the following is true?

[
"Meat-eating plants look and act like other green plants.",
"It's hard to get nutrients in the soil when acidity is high.",

For the 17 years my life was very happy. Then the first sad thing happened. My mother became very ill, and soon she knew that she was dying. Just before she died, she asked Elizabeth and me to go to her room. She held our hands and said, "Victor and Elizabeth, my children, I'm very happy because you love each other, and because one day you'll get married. Everyone in the family loves you, Elizabeth. Will you take my place in the family, my dear? I can die happy if you look after them when I have gone." My mother died and we were very sad, because we loved her dearly. Elizabeth was brave and helped us; her sweet smile gave us some happiness in the unhappy days after my mother's death. The time came for me to go to university. I didn't want to leave my sad family, but we all knew that I should go. It was hard to leave, too, because the parents of my good friend Henry would not let him go to university with me. So I had gone alone. On my first day at university I met my teacher, Professor Waldman, who was one of the greatest scientists in the world. He gave a wonderful talk to all the students who were starting at the university. He ended his talk by saying, "Some of you will become the greatest scientists of tomorrow. You must study hard and discover everything that you can. This is why God made you intelligent--to help other people." After the professor's talk, I thought very carefully. I remembered the storm when I was 15; I remembered how the lightning had destroyed the tree. From then on, I wanted to use electricity to help people, and I wanted to discover the secrets of life. I decided to work on these two things. I started to work the next day. I worked very hard and soon Professor Waldman and I realized that I could learn to be a very good scientist. The professor helped me very much, and other important scientists who were his friends helped me, too. I was interested in my work and I did not take one day's holiday during the next two years, I did not go home, and my letters to my family were very short. After two years, I had discovered many things and I built a scientific machine that was the best in the university. My machine would help me answer the most important question of all. How does life begin? Is it possible to put life into dead things? To answer these questions about life I had to learn first about death. I had to watch bodies from the moment when they died and the warm life left them. In the hospital and in the university, I watched the dying and the dead. Day after day, month after month, I followed death, so it was a dark and terrible time. I built a tall mast about 150 meters high, which is higher than the tallest building in the city, to catch lightning and send the electricity down to my machine in the lab. I believed I could use that electricity to give life to things that were dead. Then one day, the answer came to me. Suddenly I was sure that I knew the secret of life. Victor did all the following during his research in the university EXCEPT that _ .

Rice plants normally grow well in still water. But most will die if they are completely underwater for more than four days. Now, researchers have identified a gene that helps rice survive longer underwater. They say the discovery will lead to new kinds of rice plants that can survive flooding, and therefore reach their final aim, ensuring more dependable food supplies. Tests are now being done in prefix = st1 /Laos,BangladeshandIndia. The researchers say experimental rice plants with the gene have survived underwater as long as two weeks. When flooding happens, most kinds of rice plants cannot get enough oxygen, carbon dioxide or sunlight. But the scientists say crop loss depends on several conditions. These include soil conditions and plant age. Others include the amount of time the plant is underwater and the amount of fertilizer used on the crop. On a genetic map of rice, the scientists became interested in a group of three genes. They experimented with one of them, a gene known as Sub-One-A. They found that when this gene becomes very active, it improves the ability of rice to survive longer when rice is covered by water. They believe it succeeds because it affects the reaction to hormones . _ control the ability of a flooded plant to survive. Placing the gene into rice plants that are especially good for conditions inIndia, researchers say the genetically engineered plants not only survived but also produced good crops. The researchers are now trying to identify all the genes governed by the Sub-One-A gene. Being able to leave water on rice plants for an additional week might also help farmers prevent the growth of weeds. Less weed growth around their crops would mean less need for herbicide chemicals. What would be the best title for the passage?

Not everyonewhoteaches in acollegeor university is a professor. Many are instructors or lecturers. In fact, not even all professors are full professors. Many of them are assistant or associate professors or adjunct professors. So what do all of these different academic titles mean at American colleges and universities? Get ready for a short lecture, especially if you are thinking of a career in higher education. Professors usually need a doctoral degree. But sometimes a school will offer positions to people who have not yet received their doctorate. This person would be called an instructor until the degree has been completed. After that, the instructor could become an assistant professor. Assistant professors do not have tenure. Tenure means a permanent appointment. This goal of greater job security is harder to reach these days. Fewer teaching positions offer the chance for tenure. Teachers and researchers who are hired into positions that do offer it are said to be "on the tenure track." Assistant professor is the first job on this path. Assistant professors generally have five to seven years to gain tenure. During this time, other faculty members study the person's work. If tenure is denied, then the assistant professor usually has a year to find another job. Candidates for tenure may feel great pressure to get research published. "Publish or perish" is the traditional saying. An assistant professor who receives tenure becomes an associate professor. An associate professor may later be appointed a full professor. Assistant, associate and full professors perform many duties. They teach classes. They advise students. And they carry out research. They also serve on committees and take part in other activities. Other faculty members are not expected to do all these jobs. They are not on a tenure track. Instead, they might be in adjunct or visiting positions. A visiting professor has a job at one school but works at another for a period of time. An adjunct professor is also a limited or part-time position, to do research or teach classes. Adjunct professors have a doctorate. Another position is that of lecturer. Lecturers teach classes, but they may or may not have a doctorate. What can be inferred from the passage?

"It was all his own idea, " says Pat Peters, the 38-year-old wife of Palo Alto, California high school . Bob had just drawn up a "motherhood contract" ----- a document stating that for 70 days this summer he would take over the care and feeding of the couple's four children, plus all household chores . Although he didn't even know how to make coffee when he signed, he was quite confident.(He thought the experience would make a nice book.) After 40 of the 70 days, he was ready to give up. "I was beaten down, completely humbled, " admits Peters. Three weeks later he spoke to the local press (also part of the bargain), stating, "Not only is motherhood a difficult task, not only is it never-ending, it is an impossible job for any normal human being." Bob and Pat were high school sweethearts. After they were married in 1960, she worked as a secretary to help put him through university. Since then Bob has been the football and wrestling coach at Palo Alto's Cubberley High while Pat raised the kids. Then two years ago Pat went back to work as a secretary at Cubberley. "I had been around children so much," she sighs , "I couldn't talk to a grown-up." She continued to run the household, however----- until Bob signed the contract, whereupon she decided to relax and enjoy it. Although Peters had consulted with his school's home economics teachers and the head of the cafeteria , his meals were sometimes a disaster. "I tried to slip the butter I'd forgotten under the eggs after they were frying, " he says. For the last three weeks, the family ate out a lot--sometimes having Macdonald's hamburgers for lunch and dinner. As for housekeeping, a home economics teacher had told Bob that a room always looks clean if the bed is made. "I found an easier way-----I shut the doors, " he says. Soon the kids were wearing the same clothes for a week. "I made them wear their shirts inside out, and when we went to pick up Pat at work they turned them right side out so they would look clean." Now that Bob has publicly admitted he was wrong, he is routinely sharing the child-raising and household tasks with Pat. The tentative title of his book about the summer is taken from something he shouted at the kids one day. It was agreed that if Bob failed to keep to the contract, he would have to _ .

Bats are the only flying mammal in the world. They can't see very well. It is long believed, in many places, that all bats are blind . "Blind as a bat" is often heard. Yet they have no trouble flying in the darkest nights and finding their way around. How can bats fly and see at night? They fly by radar . The bat's radar system works the same way as the one that ships and planes use. When a bat flies through the air, it makes sounds that people can't hear. If the sounds hit things, they will come back. The bat's ears can receive the messages. In this way it can know where the things are. Bats go out to look for food at night. In the daytime they stay in some dark places. Some people think bats are bad animals. In fact, they are useful animals. Which of the following is True?

Kilimanjaro Climb : a Rite of Passage for Father and Son Climbing Kilimanjaro is a transformational experience for many people. The things that make the mountain hard are the very things that make it so powerful. In the case of my son Josh and I,the walk up Kilimanjaro proved a powerful symbol ofhis transition into manhood, and a great change in our relationship. Day three on the mountain, Josh was hit with massive headaches. He told me every step felt like a nail driving into his head. And then, on the night we climbed the crater rim, less than 40 minutes from the summit, Josh fell. I was walking ahead, and did not even see it. He was so exhausted that he could not get up. He recalled our guides, debating whether or not they should take him straight down. Josh _ He forced himself to his feet, shook the guides off. He set his face towards the peak and just kept marching. Near the summit he caught up with me and we reached the peak together. " I've never been in so much pain and so happy at the same time,,,he said, as we sat side by side on the frozen rock and looked down over Africa. "You know, in the past when we'd go on camping and rafting trips, you guided and took care of me through it all. But on Kilimanjaro it was different. From the bottom up, I climbed it. I never feltlike a kid, even when 1 was in pain. You never acted like a parent." "That's not quite true,"I replied. "When you told me that on the summit you fell-and I did not even notice, my first thought was, 'Oh my God! I'm such an awful parent!' But then it hit me, 'He got himself up. He walked to the peak on his own. He didn't need me to help.," I realized as I spoke that two people had died that night on Kilimanjaro. A child and a parent. It wasjust two friends who walked down the mountain together. What can be inferred from the talk between the father and the son?

The World Health Organization(WHO)planned to study the relationship between the eating habits of the people and the disease.Two doctors were chosen to make the study. They flew to Africa south of the Sahara and during the next two months visited ten countries.They found that serious diseases of poor eating, often mistaken for other diseases, existed in all parts of Africa.The diseases were similar and could therefore all be named kwashiorkor .The diseased children are usually from one to four years old.As the illness progresses, the child's stomach becomes swollen by liquid collecting in the body.The skin changes colour and may break out in open sores.The hair changes colour and starts to fall out.The patient loses all interest in his surroundings and even in food, and becomes so weak that he wants to lie down all the time.Stomach liquids are no longer produced. The doctors reasoned that kwashiorkor was found in the young children of this age in many parts of Africa because of lack of milk or meat.Their mothers gave them foods full of starches instead of greatly needed proteins.They found that the addition of milk to the food of children suffering from kwashiorkor saved many lives. What is mentioned as a simple but reasonable way of curing this disease?

The Internet is becoming important in our life. How much do you know about it? The following questions and their answers will help you to know more about the Internet. What is the Internet? The Internet is a large, world-wide collection of computer networks . A network is a small group of computers put together. The Internet is many different kinds of networks from all over the world. These networks are called the Internet. If you have learned to use the Internet, you can have a lot of interest on the World Wide Web . What is the World Wide Web? The World Wide Web has been the most popular development of the Internet. It is like a big electronic book with millions of pages. These pages are called homepages. You can find information about almost anything in the world on these pages. For example, you can use the Internet instead of a library to find information for your homework. You can also find information about your favourite sport or film star, talk to your friends or even do some shopping on the pages. Most pages have words, pictures and even sound or music. What is e-mail? Electronic mail (e-mail) is a way of sending messages to other people. It's much quicker and cheaper than sending a letter. If you want to use e-mail, you must have an e-mail address. This address must have letters and dots and an @ (means "at"). For example: Lily @ Yahoo.com. Write a message, type a person's e-mail address, and then send the message across the Internet. People don't need to use stamps, envelopes or go to the post office because of the invention of the Internet. Quick, easy and interesting -- that's the Internet. The sentence "You can talk to your friends on the pages." means _ .

For example, imagine that you and your friends are arguing about who are the most popular music or movie stars, you can decide the argument by writing the names in the Googlefight boxes. Let's say that you are arguing about Jackie Chan and Jet Li. You will quickly discover that Jet Li is mentioned 16 million times on Google pages, whereas Jackie Chan is mentioned a mere 12 million times! In this unscientific way, you can claim victory for one Star over another. But teachers have come up with ways of using Googlefight which are much more useful from an academic point of view, particularly when it comes to studying languages. You can, for example, find out the frequency of two words with the same meaning, and deduce from the answers which one is more common. For example, let's take the words "buy" and "purchase", which mean the same thing (although "buy" is only a verb and "purchase" is both a verb and a noun). It is immediately clear from Googlefight that "buy" is much more commonly used, with a massive three and a half billion hits, compared to only one billion occurrences for the more formal word. But the real value of Googlefight to the language learner is in determining which is the more common of two phrases. For example, "raining cats and dogs" is an old-fashioned English expression about the weather. Do English speakers still use it? Or are they more likely to say "pouring down"? Googlefight suggests the latter. "Pouring down" has 898,000 Google hits, whereas "raining cats and dogs" only has 326,000. With phrases, it's important to remember that you need to use quote marks to make the search more accurate. For example, if you type in the similar phrases "look after" and "take care of " without quote marks, the second phrase seems to be more common, but with quote marks, the result is reversed. What is Googlefight?

Old Computers Make for Unhappy Workers --- Survey LONDON (Reuters) ----- Dealing with the dissatisfaction of aging and unreliable office computers leads to workers' unhappiness and more sick leave, a survey showed on Wednesday. A survey carried out by caro4free.net of over 2,700 European office workers from the UK, France and Germany found that workplace dissatisfaction increased greatly with the age of the computer equipment. "We do know that job satisfaction is falling in Britain and most advanced nations," said Stephen White, a researcher from the Work Foundation. "The actual reasons for _ are the subject of very heated discussion. It's certainly one interesting theory that technology may be the cause of this in some way," White added. A quarter of these using outdated computers in Britain said they were "quite" or "very dissatisfied" with their everyday job compared to the percent of those who had enjoyed an advantage from up-to-date technology. The survey also said that among workers dealing with outdated equipment, there was a 35 percent greater probability they would take six or more days of sick leave per year compared with the average worker. In France, where more workers use old computers, the probability jumped to 55 percent. Results also showed that women in the three countries were more likely to be using outdated equipment. In the UK, where more workers have up-to-date computers than in the other countries surveyed, the number of women using old equipment doubled that of men. White pointed out that there were two sides to this problem, saying that continuously having to deal with new technology and equipment can also be a source of worry. "Old and faulty equipment is a major cause of office dissatisfaction. There is no question about it; but you also have to say that the frequent change of equipment is also, or could be, a main cause of dissatisfaction." How many office workers use old computers in Britain expressed their dissatisfaction?

Have you eaten too much over the holidays? You should try fidgeting for a while. Those around you might not like it, but scratching (moving your nails against a part of your body) and twitching (moving suddenly and quickly when you don't want to) is an important way of burning up calories . American researchers have found that some people's squirming (continuously turn your body when nervous) and wigging (move in small movements, especially from side to side) equals several miles of slow running each day. The scientists, based at the National Institute of Health's laboratory in Phenix, Arizona, are studying why some people get fat and other stay slim. In one study 177 people each spent 24 hours in a room in the institute where the amount of energy is measured by their oxygen and carbon dioxide levels. By the end of the day, some people had burned up 800 calories in toe-tapping, (moving the front part of your foot up and down) finger-drumming (hitting your fingers continuously and lightly against something hard) and other nervous habits. However, others had burned up only 100 calories. The researchers found that slim women fidget more than fat women, but there was no significant difference in men. Heavy people burn up more energy when they fidget than thin people do. According to the scientists, the reason why some people get fat and other people stay slim is that _ .

Dear Victor: I am a college student. Nowadays games on the net are very popular with college students. Some of my roommates are very interested in them. They not only play games in their free time, but also keep talking about them at night when lights are off, and they regard games as part of life. I've begged them to give it up, but they wouldn't listen to me. It has become a rather big problem. Should I report it to our teachers or do something else? Ted, Dear Ted: Drop it. Your roommates, as grown-ups, can do whatever they want with their time so long as it doesn't break school rules or violate other people's interests. Playing perhaps gives these students relaxation from hard study. If they play too often, have little time to study, and they will _ , but you will not. Reporting to the teachers would only harm your good name in your dormitory . However you have rights to ask your roommates to be quiet when you need sleep.

You may know about " junk food" like French fries. But do you know about "junk sleep"? Recently, a British survey found that electronic products in teenagers bedrooms are affecting their sleep. The survey was done among 1,000 British kids from 12 to 16. It found that thirty percent of them got just 4 to 7 hours sleep every day. But doctors say they need 8 to 9 hours. Almost a quarter of the kids said they fell asleep more than once a week while watching TV, listening to music or using other electronic products. "This is very worrying." Said Dr Chris Idzikowski, a British expert, "We call it 'junk sleep', It means you don't get enough sleep and the quality of the sleep is bad, too. If you don't get good rest, you don't perform well in school the next day." The survey found that 40 percent of the kids felt tired each day, with girls between 13 and 16 feeling the worst. Nearly all the teenagers have a phone, Mp4 or TV IN THEIR BEDROOM. And many of them have all three. Which of the following is the best solution to the problem?

I resisted for years becoming anything like my dad or at least acknowledging that I was anything like him because, well, because I wanted to be me, not him; but there I sat at his memorial service several months ago, telling myself,"You've got a lot more of your dad in you than you think." There's this phrase my dad used, and I know I'm going to sound rude to complain about it, but it did use to bother me."I'm so proud of you,"he told us kids, whether we'd won a sailing race or run a marathon or managed to get a book published."I'm so proud of you."That should be a good thing, but here's what always went through my unforgiving mind: You're taking credit for what isn't really yours but mine."I'm so proud of you."It came out of my dad's mouth all the time, on those long-distance calls where I might have mentioned something that happened at work or when he and Mom came to visit and we showed off the talents of our two boys. I knew the feeling of parental pride well, especially when my boys achieved in ways that were beyond my comprehension and ability, but I looked for other ways to express it."That's an incredible story you've written,"I would say about the composition."I can't believe how fast you solved that problem,"I would admire the work of the math genius. But never just the blanket phrase. But there I was at Dad's memorial, about to praise him, thinking that I could say exactly what my brother said,"He lets me be me."That was his achievement. In the phrase that I promised I would never utter to my children was a world of forgiveness, care and appreciation. So just the other day when my older son, now a promising manager, sent me an email about the thank-you dinner his latest client threw him, I thought hard for clever things to say, finally realizing my kids just want what my dad gave me."I'm so proud of you,"I wrote. Just like the old man. How does the writer express his parental pride?

On a Saturday morning earlier this September, the world got its first look at the Strati. This electric vehicle is unlike any other currently on the road. It rolls on four wheels, but its body and chassis weren't built in a factory. Instead, Strati's designers used a technology called 3-D printing. It created those parts of the car in one piece, from the ground up. "Compared to a typical vehicle on the road, the Strati definitely looks different," says Greg Schroeder, a senior research engineer at the Center for Automotive Research in Ann Arbor, Mich. He did not work on the new car. His organization studies trends and changes in the auto industry. It took 44 hours to print the new car at the International Manufacturing Technology Show in Chicago. Over the next few days, the car's designers installed additional parts. These included the car's engine, brakes and tires. Then, early on September 13, Jay Rogers climbed into the car, started its engine and drove the vehicle onto the street. Rogers helped found Local Motors. It's the Arizona-based company behind the Strati. Two weeks later, his team printed a second Strati, and just as fast, at a fair in New York City. Justin Fishkin, a local Motors official, sees the Strati as a window into the future. Today, car buyers are limited in their choice of a vehicle. They can order only what car companies have already designed. But in the future, he says, you may be able to design your own car online and then get it printed to order. Manufacturing experts say 3-D printing has begun to revolutionize how they make things. The technology has been around for decades. But these machines used to be so expensive that only large companies could afford them. In the last few years, though, that has changed. Many of the machines are now inexpensive enough for small companies--or even individuals --to own. Some local libraries make them available to the public. High Schools are beginning to use them in classrooms. Wide access to these printers means people can now design and print a wide variety of new things. The car's printer is a one-of-a-kind device. The technology behind the 3-D printer used in Chicago is an example of additive manufacturing. This process builds solid objects, slice by slice, from the bottom up. ("Strati" means layers, in Italian.) A mechanical arm moves a _ from one side to another, back and forth. As it moves, the nozzle deposits a liquid--often melted plastic or metal (but it could be food, concrete or even cells) --that quickly hardens or bonds to become solid or semi-solid. This creates a single, thin layer. Once a layer is complete, the printer starts depositing the next one. "There's a lot of interest in 3-D printing in the auto industry," says Schroeder. Right now, the technology is particularly useful for building models of cars or car parts. To compete with current auto manufacturers, the 3-D printer would have to increase in a hurry, Schroeder says. By contrast, he notes, a Ford F-150 pickup truck rolls off an assembly line at a rate of roughly one per minute. To print as many Stratis would require many more printers. Schroeder says he doesn't see 3-D printing soon taking over for such high-volume manufacturing. But, he adds, "Who knows what will happen in the long term?" Scientists at Oak Ridge National Laboratory in Tennessee designed the 3-D printer used in Chicago. Lonnie Love, a research scientist at the lab, led the effort. Additive manufacturing often is slow and expensive. It also may produce materials that are unreliable, Love says. So for two years, his team searched for ways to make 3-D printing better. They built new machines and tested them over and over. All of that work paid off: their new machine is fast and uses less expensive material than earlier printers. In addition, it prints a plastic embedded with fibers of carbon to produce a stronger material. This helps ensure the material won't crack or break under pressure. Which of the following can be the best title for this passage?

One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem ,while the student claimed a perfect score. I was elected as their arbiter( ).I read the examination problem: "Show how it is possible to determine the height of a tall building with the aid of a barometer ." The student had answered: "Take the barometer to the top of the building,attach a long rope to it,lower it to the street,and then bring it up, measuring the length of the rope. The length of it is the height of the building. " The student had really answered the question completely ,but the answer didn't confirm his competence in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and clashed off one, which read: "Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula to calculate the height of the building. " At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others ,and then added5"Probably the best is to take the barometer to the. administrator and said to him,' Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you.," Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did ,but said that he was fed up with high school and college instructors trying to teach him how to think. The name of the student was Bohr who later was famous all over ,the world. He won the Nobel Prize for Physics in 1922. We know from the passage that _

Joseph Francis Charles Rock (1884-1962) was an Austrian-American explorer, botanist, and anthropologist . For more than 25 years, he travelled extensively through Tibet and Yunnan, Gansu, and Sichuan provinces in China before finally leaving in 1949. In 1924, Harvard sent Joseph Francis Rock on a treasure hunt through China's southwestern provinces--the Wild West of their day. But gold and silver weren't his task: Rock, a distinguished botanist, sought only to fill his bags with all the seeds, saplings, and shrubs he could find. During his three-year expedition, he collected 20,000 specimens for the Arnold Arboretum . Botany, though, was just one of Rock's strengths. As an ethnologist , he took hundreds of photographs of the Naxi, a tribe in Yunnan province, recording their now-lost way of life for both Harvard and National Geographic, and took notes for an eventual 500-page dictionary of their language. His hand-drawn map of his travels through China's "Cho-Ni" territory, in the Harvard Map Collection, includes more than a thousand rivers, towns, and mountains indicated in both English and Chinese, and was so well made that the U.S. government used it to plan aerial missions in World War II. Scientist, linguist, cartographer, photographer, writer--Rock was not a wallflower in any sense. Arrogant and self-possessed, he would walk into a village or warlord's place "as if he owned the place," said Lisa Pearson, the Arboretum's head librarian. In declaring his successful return under the headline "Seeking Strange Flowers, in the Far Reaches of the World," the Boston Evening Transcript ran a large photo of the daring explorer wearing in a woolly coat and fox-skin hat. "In discussing his heroism including hair-raising escapes from death either from mountain slides, snow slides and robber armies, he waves the idea away as if it is of no importance." The Arboretum and Rock parted ways after 1927, mainly because his trip cost Harvard a fortune--about $900,000 in today's dollars. Fortunately, many of his specimens, many of his amazing photos, and his great stories remain. What is the passage mainly about?

One day a lonely girl found two weak birds while she was walking in the woods . She took them home and put them in a small cage. She fed them with love and the birds grew strong. Every morning they greeted her with a beautiful song. The girl loved them very much and wanted their singing to last forever. One day the girl left the cage's door open. The larger and stronger of the two birds flew out of the cage. The girl watched worriedly as it circled high above her. She was afraid that it would fly away and she would never see it again. So when it flew close, she grasped at it wildly. She was very happy that she held it tightly within her hand! Suddenly, she felt something had happened to the bird. She opened her hand and was surprised to find the bird was dead. Her love for the bird killed it. She noticed the other bird jumping in the cage. She could feel that it wanted to be free. It hoped to fly into the clear, blue sky. She lifted it from the cage and flew it into the air. The bird circled once, twice, three times... When the bird was flying happily in the sky, she was so glad. Just then the bird flew closer and sat softly on her shoulder. It sang the sweetest song she had ever heard. The girl felt that the other bird _ when it was jumping in the cage.

When you're surfing the Internet on your laptop from your dorm or home, do you know your personal details are being gathered secretly? And would you be surprised to know the information may be sold cheaply to advertisers and marketers? According to an investigation by The Wall Street Journal, all it takes is a tiny file in a computer-a single code consisting of a long series of numbers and letters to record the computer user's age, gender, location, favorite movies and hobbies. The newspaper reports that Lotame Solutions Inc., a New York company, uses sophisticated software called a " beacon" to capture what people are typing on a website. Lotame packages that data into profiles about individuals, only without their names, and sells the profiles to companies seeking customers. Batches of such data may be sold for a few dollars. The Wall Street Journal survey discovered that spying on Internet users is one of the fastest-growing businesses on the World Wide Web. The "cookie" a tiny text file put on your PC by websites or marketing firms which might be used to remember your. preferences for one site, or to track you across many sites is already old news. There are new and more complex tools such as "beacons " which scan in real time what people are doing on a webpage. These beacons instantly assess the Internet user's location, income, shopping interests and even medical conditions. Millions of Internet users around the world also face unprecedented threats. Private, sensitive, personal and business information is being gathered and sold without their knowledge. Companies insist the information they gather is anonymous and the data is used harmlessly. But the technology has grown so powerful that even some of the biggest websites in the US don't know that they were installing intrusive files on visitors' computers.

When we talk about red packets, the most important question is "What are you going to do with it?" One thing you could do is to put your money in the bank. Maybe you don't know, some students in Hubei began to use the Xiaogui Dangjia bank card this year. This is a card for children. It is from China Minsheng Bank in Wuhan. Wang Ming is a 14-year-old junior student in Wuhan. He said "All my pocket money has a place to go now. I can pay my own school fees ." Zhu Yu, a manager of Minsheng Bank, said that they knew lots of students who didn't know how to use their money. So they wanted them to know how to use it carefully. Parents worry that children don't know how to take care of the money by themselves. Shen qiangqiang's mother like the card very much. Shen was asking his mother for a computer for a long time, but his mother didn't buy it for him. She said, "We want him to use his card to save money for the computer. If we buy everything he asks for, he will think money comes too easily, and he won't work hard for it." Today, there are many different kinds of bank cards. They are from different banks. People put their money in them. Then they can use their money at any time. People can do many things with bank cards. They can wash cars, go shopping, eat delicious food and travel to other places with the money in their bank cards. The most important thing is not "How much did you get?"

Airtight plastic bags can help farmers protect their harvests without the use of harmful chemicals. These bags are designed to keep air out of crops in storage. Using them is a simple way to fight insects and keep crops fresh. Ten countries in West and Central Africa are involved in a project to improve the storage of cowpeas, also known as black-eyed peas. Farmers can lose much of the harvest to insects called bruchids , which grow from egg to adult in a few weeks and then lay forty to sixty eggs. They can destroy the whole harvest within months. Farmers can sell their crops immediately. But selling at harvest time means more competition and lower prices.Or they can use pesticides to kill the bugs. But a crop scientist Dieudonne Baributsa says, "They end up misusing or overusing the pesticide. In Nigeria, they have reported a lot of cases of death. They usually call cowpeas 'killer beans' in Nigeria." Mr. Baributsa is a researcher at Purdue University in Indiana, America. The project is called PICS---Purdue Improved Cowpea Storage. He says the storage bags are thick enough that any insects already in the cowpeas willdie from a lack of oxygen. The lack of air will also help prevent the growth of bacteria that can ruin the harvest. The bags cost about two dollars each. Mr. Baributsa says that is not much, especially if it means farmers can wait long enough to get a better price for their crops. The bags are produced locally. Donors currently support the project, but the groups involved are working to build a lasting market for the bags because donation for the project will not lastforever. A company based in the United States called GrainPro makes another kind of airtight bags. These are called SuperGrainbags. Phil Villers, the company's president, says storing a harvest safely not only helps farmers earn more money, but also reduces the amount of the harvest loss to insects, spoilage and mishandling. "What does not get wasted and eaten means it is possible to feed a hungry world," said Phil Villers. It can be inferred that bruchids _ .

Catalin Baciu from Romania wanted to make money in Germany. So, he and his wife, Oltita went to Bucharest, the capital city of Romania to get legal papers to move to Germany. However, when they arrived, they were surprised by what they saw. "Hundreds of street children were living in a busy and dirty city of two and a half million people. Many of them were using drugs. They all seemed lost. Most of them were under ten years old. Oltita had tears in her eyes," Catalin said. Many of these streets children were orphans . They had grown up in the government orphanages, but had run away. They thought any place would be better than the orphanages. But the streets were cold and hard. The winters were freezing. The children had to sleep in warm sewers under the ground. Many of the children even became involved with crime and violence . The Baciu's did not like the sight of so many pitiful children in Bucharest. They wanted to leave immediately and go to Germany. However, that night, Catalin and Oltita stayed with a friend in Buchares. "The friend we were staying with was working with street children. I was deeply touched by what he and his fellows were trying to do...they were sacrificing their jobs and lives to save street children, " Catalin said. After that visit, the Baciu's completely changed their life plan. Instead of moving to Germany, they began working with street children in Bucharest. They started by opening a home called House of Hope, which provided a warm and loving place for children who needed to get away from the streets. Many hospitals and business workers called House of Hope when they found troubled kids. Everyone knew the House of Hope would help. Oltita had tears in her eyes because _ .

In the past, people who graduated from college felt proud of their academic achievements and felt confident that their degree would help them to find a good job. However, in the past five years the job market has changed greatly. This year's college graduates are facing one of the worst job markets. For example, Ryan Stewart, a graduate of San Jose State University, got a degree in religious studies, but no job _ He points out that many people already working are getting laid off and don't have jobs, so it's even harder for new college graduates to find jobs. Five years ago, the future looked bright for the class of 2006. There were many high-tech job chances. Graduates received many job offers, and they were able to get jobs with high salaries and benefits such as insurance and paid vacations. However, "Times have changed and it's a new market," according to an officer of the San Jose State Career Center. The officer says students who do find jobs started preparing two years ago. They worked during summer vacations, they have had several short-time jobs, and they've majored in one of the few fields that are still hot, like chemical engineering, accounting, or nursing, where average starting salaries have actually increased over last year. Other popular fields (like information system management, computer science, and political science) have seen big declines in starting salaries. Ryan Stewart (he had hoped to become a teacher) may go back to school in order to become a college teacher. He thinks college teaching could be a good career even in a bad economy. In conclusion, _ For now, they can only hope the value of their degree will increase over time. Ryan Stewart will have to _ .

Some recent surveys show that the health conditions of many white collar employees and office workers are rather dangerous. Death cases among white collar employees and office workers are increasing year by year and these cases are generally believed to have been caused by overwork and spending little time taking rest or doing exercise. If their offices are within the distance of half an hour's walk, some office workers now choose to go to work on foot. Ms. Deng, who works in a foreign enterprise in Beijing, has been walking to her office for more than six months now. " I usually have a tight work schedule and can't find time to do exercise. So I choose to walk to work. " As she said, if the office is not far from home, most women would like to go to work on foot. Walking is good for their health and can help them to keep good figures as well. Apart from walking to office,one can also find time to do exercise when one is at work. The simplest way is to desert the lift. Mr. Wei, who works in the Passenger Service Department at Shenzhen Airlines, is one of such men who frequently climb stairs. " I only use the lift whenever I'm with my colleagues or my boss. Otherwise, I would climb stairs instead of taking the lift. " In addition, some office workers try to find time to go to a gym at the end of a day. Ms. Sang works in a law firm in Shenzhen. She goes to the gym several times a week when she has the time. " I go to the gym every weekend. During the weekdays,I will also go there whenever I have the time. " Ms. Sang and her husband both have a gym membership card for a whole year. The cards cost them 3000 yuan. However, they think it's worth it. The best title of the passage is _ .

Everyone takes drugs.Sometimes a drug might be called a herb but the effect is the same.Drugs and herbs can make life better for they are used to improve health.From the simplest headache to a cure for cancer, people believe that certain drugs can help them.But there is danger if the drugs are not used in a proper way. American teenagers sometimes use certain drugs to feel good.They call this "getting high".The problem is that once a young man or a young woman has the feeling of"getting high",they want to do it often.If school is boring or too hard,students might get depressed and a drug or herb might help them feel better.If the student takes too much of a drug,the body may change in a wrong way such as a confused mind,poor sight,a headache,and an uncomfortable stomach. Schools now have D.A.R.E.program which means Drug Abuse Resistance Education.This program was started so that young students from age 10 to 18 might understand how a drug affects their bodies.The main point of the program is education.Once a student understands certain drugs can cause ill health,he will know he should not use them. Education is the key to good nutrition as well.If a student eats correctly,he or she will be full of energy which leads to good study habits and good grades.Poor nutrition may cause the need for more sleep and poor concentration.Proper food is similar to the proper use of drugs.Both allow a healthy body to grow while misuse of them prevents a person from developing normally. We can infer from the passage that_.

The best swimmers tend to be tall and thin with long arms, long legs, long feet, and long hands. The size of their hands gives them great "water grasp", and only a very small hand movement keeps them afloat. They also have great strength, endurance, insulation against heat loss while in water below body temperature, thus better energy conservation, low resistance when in the water, and swimming stroke mechanics . Part of the reason why some people are better swimmers than others has to do with body density. The average person's body density is slightly less than that of water. Muscle has greater density than fat. Therefore, very muscular people tend to be poor at staying afloat. Bone has greater density than fat. Therefore, very skinny people tend to be poor at staying afloat. Good buoyancy is not necessarily the most important factor in good swimming, but it certainly helps. For example, great competitive swimmers--tall, thin, and usually more muscular than average--tend to have greater body density than average and less buoyancy. Many would not float very well if they remained motionless in the water. Their much greater "water grasp" makes up for it. www.ks5u.com The average woman contains a higher proportion of fat in her body than the average man, and the average man contains a higher proportion of muscle in his body than the average woman. Therefore, in general, women are better floaters than men. Compared with other competitive sports, the performance of women is closer to that of men in competitive swimming. Buoyancy is important because_.

Consumer electronics once again topped the list of the most wanted gifts this holiday season. "Seventy-six percent of consumers who plan to buy holiday gifts say that they will spend money or buy at least one technology product; definitely a solid vote of confidence for technology." Steve Koenig is with the Consumer Electronics Association. He says the group's latest research also shows that Americans this year are spending more on technology products. " " From tablet computers to smart phones, American shoppers have been lining up to get the newest and coolest electronic devices on the market. There are more choices today than ever before. "It's kind of hard to make a decision." Tablet computers are one of the best-selling products this year. Brian Tong is Senior Editor of CNET.com. The website reports on tech news and examines the latest electronic products. He says the Apple iPad Mini is one of the most popular tablets. Its starting price is $329. One of Apple's biggest competitors is the Google Nexus 7. It starts at $199. " is more powerful than what's in the iPad Mini, but also it offers you a lot of things like maps that work better than Apple's maps. But Brian Tong says there is one reason why people may like the iPad Mini more than the Nexus 7. "If you just want to read books and surf the Internet, you don't really need to get an iPad Mini, but if you want the largest robust group of apps that's where the iPad and Apple's ecosystem shines the most." Elman Chacon is with the electronics store Best Buy. He says another hot product this season is smart cameras. They connect to the Internet through WiFi. This makes it easy for users to email or upload photographs directly from the camera. "You can literally take a picture and upload it into your Facebook in a matter of seconds. These things are pretty cool because they do a lot of things." Streaming media boxes also connect to the Internet. People are able to watch web content such as movies and YouTube videos on their televisions. Another popular item is wireless speaker systems.

Can you imagine living in the desert for a whole year, watching the activities of a group of busy ants? Deborah Gordon did exactly that. She finally found out that there were four main groups of workers in the ant team: cleaners, haulers , gatherers and security ants. Each group did their own job to finish the task of the whole team. Cleaner ants carried waste food from inside the nest to outside. Hauler ants walked on the top of the nest and cleared rubbish. Gatherer ants went out to find food for the whole team and security ants fought against anyone who wanted to hurt the members of the team. While she was watching the ants in the desert, Deborah found that the most interesting part was watching the ants dealing with difficulties, such as fighting against other insects that wanted to destroy their nest, or a big fire. At those moments, they would all stop what they were doing and go to help security ants to protect their home. What do we do when people around us meet difficulties? What have we done to turn our world into a better place? It's time to think. Which of the following is TRUE according to the passage?

I'm afraid to grow old--we're all afraid. In fact, the fear of growing old is so great that every aged person is an insult and a threat to the society. They remind us of our own death, that our body won't always remain smooth and responsive, but will someday betray us by aging. The ideal way to age would be to grow slowly invisible, gradually disappearing, without causing worry or discomfort to the young. In some ways that does happen. Sitting in a small park across from a nursing home one day, I noticed that the young mothers and their children gathered on one side, and the old people from the home on the other. Whenever a youngster would run over to the "wrong" side, chasing a ball or just trying to cover all the available space, the old people would lean forward and smile. But before any communication could be established, the mother would come over, murmuring embarrassed apologies, and take her child back to the "young" side. Now, it seemed to me that the children didn't feel any particular fear and the old people didn't seem to be threatened by the children. The division of space was drawn by the mothers. And the mothers never looked at the old people who lined the other side of the park. These well-dressed young women had a way of sliding their eyes over, around, through the old people; they never looked at them directly. The old people may as well have been invisible; they offended the aesthetic eye of the mothers. My early experiences were somewhat different; since I grew up in a small town, my children had more of a nineteenth-century flavor. I knew a lot of old people, and considered some of them friends. People are afraid of growing old because it is usually associated with _ .

Scientists have written a report on the future of trade and industry. They talk about the role robots will play in industry. What is a robot?Basically ,it is a machine which is designed to do the work of a human being. It is usually controlled by a computer. Once it has been given a set of things to do,it will do the job on its own. Nowadays,Britain has 120 robots at work in industry. This compares badly with other industrial countries. In Japan,there are 4,000 robots in use. In the USA there are 2,000 and in Germany there are 500. According to the report,the government must help people understand how robot technology can be used. Also,people must be educated to know how important this new technology is. The designing of new robots will be very important in the future. The report says that special robot centres should be set up where people who design robots and people who will use them work together. The assembly work of the future will be complex . So firms must develop robots to do it. A robot is a kind of _ .

You might notice something new in the next few years as you watch Disney programs: Starting in 2015, there won't be any candy, sugary cereal or fast-food commercials aimed at kids. The Walt Disney Company has become the first major media company to ban ads for junk food on its TV channels, radio stations and websites. It hopes this will stop kids from making poor food choices. First Lady Michelle Obama called it a "game changer" that is sure to send a message to the rest of the children's entertainment industry. "Just a few years ago, if you had told me or any other mom or dad in America that our kids wouldn't see a single ad for junk food while they watched their favorite cartoons on a major TV network, we wouldn't have believed you," said the First Lady, who heads a campaign to help stop child obesity. The ban would apply to Disney-owned ABC stations as well as Radio Disney and Disney-owned websites aimed at families with young children. In addition, Disney plans to make changes to its kids' menus at theme parks and resorts . Fast-food options will be replaced with healthier choices, such as smoothies , apples, vegetables and yogurt. In addition to candy bars and fast-food meals, other foods that don't meet Disney's nutritional standards will be banned from the company's kid-targeted media. Any cereal with 10 grams or more of sugar per serving will be _ . There will be no ads for full meals of more than 600 calories. Juices with high levels of sugar and foods with too much salt will also be pulled. Leslie Goodman, Disney's senior vice-president of Corporate Citizenship, said a company that wants to advertise will need to show that it offers a range of healthy options. Disney isn't the only one pushing away unhealthy foods. Last week, New York City Mayor Michael Bloomberg suggested a ban on drinks over 16 ounces sold in movie theaters, restaurants and convenience stores in the Big Apple. He says large, sugary drinks are partly to blame for obesity. What will the Walt Disney Company do from 2015?

The new iPhone 3G should please everyone . Its look and feel are only slightly improved, but a faster network loads Web pages more quickly , true GPS functionality allows it to easily find places nearby , and the new $199 price(down from $400) makes it an affordable luxury. Before deciding whether to buy, however , make sure you can actually take advantage of the iPhone 3G's high-speed data network. 3G stands for third-generation , which in non-geek speak translates to Web pages and mail messages that, ideally, load about three times faster than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf the Web at the same time . That's great, if you live or work in a place where the 3G network of AT&T (the sole wireless carrier of the iPhone) is active. That's not so great in cities like New York where AT&T's cellular coverage is awful. As one of my colleagues in New York City, who bought the original iPhone , commented , "It's just a toy . You can't make phone calls on it, so I carry my Verizon phone with me all the time." The real fun begins when you tap on the icon called "Apple Store" and start browsing the hundreds of add-on applications that have been developed just for the iPhone. You will find tons of games (I like JirboBreak , a free game inspired by the Atari classic Breakout ) and mobile version of popular websites like Pandora , Facebook , MySpace and the New York Times . Most apps will cost you , but the vast majority are $9.99 or less. The apps work on the old iPhone too, but you'll enjoy them a lot more on the iPhone 3G because many of the programs , including Yelp(local business reviews ), Whrrl (mobile social networking) and UrbanSpoon(restaurant reviews), use you exact location --- provided by the iPhone 3G's GPS chip --- to make recommendations. The apps also load much faster over the 3G network. . The new iPhone 3G has following features except that _ .

Florence Nightingale was born in 1820. Growing up, she was a quiet and serious girl. She spent a lot of time playing with her dolls. She would pretend that the dolls were sick and she was their nurse. People would bring sick or hurt animals to her to look after. She even managed to mend a dog's broken leg when she was a young girl. She often went with her mother to visit the poor people. They took food and medicine to the sick. It was these visits that gave her the idea of becoming a nurse. Florence really wanted to be a doctor but she couldn't because in those days only men were allowed to become doctors. She decided that she wanted to become a nurse. Her parents were very angry;the daughters of rich people did not work at all and certainly they did not become nurses. But Florence had made up her mind to specialize in nursing. Her chance came in 1854 when Britain went to war with Russia in a place called the Crimea. Florence was asked to take a group of nurses to look after the sick and wounded soldiers. The hospitals were dirty, and there was not enough medicine. There were not enough beds, so some people were just lying on rags in the mud. There was so much sickness that the doctors could not treat all the soldiers. Florence and her team cleaned the hospital rooms and beds. They made sure that the soldiers got enough medicine. The army was unhappy because there were women so close to the fighting. They gave the nurses a lot of trouble. Florence and her team worked hard and got over all the difficulties they had to face. Florence became famous as "The Lady of the Lamp". At night she would go from room to room checking on the patients. There was no electricity so she would carry an oil lamp with her to see where she was going. She often stayed to talk to the patients. After the war, Florence returned to London as a national hero. A great welcome was prepared for her, but she slipped into the country unnoticed. She opened a school to teach nurses how to look after their patients properly. She never really got better from the illness that she had in the Crimea and she died in 1910. Now Florence Nightingale is known as the mother of modem nursing. She had devoted her whole life to patients. It is because of her work that we receive the proper care in hospitals today. Nightingale had the idea of becoming a nurse when _ .

On Oct4,2011 , I phone 4s made its international appearance at the press conference claimed by the Iphone cooperation . Ever since then , Iphone4s has become _ and even made a fashion around the globe. Meanwhile , many new expressions come about in relationship with this type of high-tech products. "Jailbreak" is one of them. " Jailbreak" means to unlock the operating system of a mobile phone or other device so that it can run software which it is not normally authorized to use because of restrictions imposed by the device's manufacturer. If someone jailbreaks a smartphone, tablet computer or other device , they use a special piece of software in order to remove the restrictions imposed by the manufacturer on the kind of applications that can be downloaded and run on the device. The concept of jailbreaking is most often associated with products from Apple Inc, such as the iPhone, iPod and iPad, which routinely restrict the user to applications licensed exclusively by Apple and purchased via its App Store. As well as wanting to lift the restriction on what kinds of applications they can purchase, those who jailbreak often do so as a reaction against what they consider as a form of censorship imposed by Apple Inc in only allowing the use of their 'approved' apps. The concept of jailbreaking dates back to July 2007, when it was applied to the iPhone within a month of the device's first release. This first occurrence related to the adding of custom ringtones , but the idea quickly developed as a means to lift the restriction and equip the phone with games and other applications not licensed by Apple Inc. jailbreak means that _ .

Brooke Martin's golden retriever Kayla hated being left alone or separated. She would howl, pace, and chew on things. Brooke learned that other people had the same problem with their pets. She wondered: --What if you could talk to your dog if you were gone? Working with her father in their garage, the 16-year-old came up with several ideas. Finally, she invented a device that allowed pet owners to video chat with their pets! She calls the device iCPooch. --The dog doesn't have to answer the call,explains Brooke. --It comes up immediately on the screen on their end. It's a two-way audio and video--you can see and hear each other.With a click of a button you can even send the dog a treat! Her invention has earned her a spot competing against nine other finalists in a young scientist competition for middle-school students. These finalists, selected based on their short video presentations, are working with mentors over the summer before heading to the final competition in St. Paul, Minn. After Martin's video put her among the 10 finalists in the Discovery Education 3M Young Scientist Challenge, she was paired with Delony Langer-Anderson, a product development scientist in 3M's consumer health care division. --I just lead her down the product development path,Langer-Anderson told Live Science. This path includes guidance on how to test the potential product, which combines a video chat device that answers immediately on the dog's end with a dog treat device the owner can remotely activate. One thing I have thought about a lot is, what happens if while the device is on the floor, what if your dog knocks it over, or scratches the screen? Martin said. She and Langer-Anderson discussed this, and Martin is now testing materials at a local dog shelter by taping them to the dog house floors to see how well they withstand sharp teeth and claws. The finalists create models they can test, with the guidance from a mentor. Their projects include a fuel cell that transforms cut grass into electricity and an app that rewards drivers for not texting or calling. Langer-Anderson tries to help the students work through the scientific method, testing their hypothesis, in a determined way, --so the kids don't get buried in data.she said.

If you've ever been to a social gathering, you might feel awkward and uncomfortable. While social gatherings can be very enjoyable, especially when you are surrounded by people whose company you enjoy, there are social events that you sometimes find yourself wishing you were someplace else. Such occasions can sometimes be the cause of much anxiety and self-consciousness. You may even feel like everyone else is having a good time except for you. Yet the truth is that everyone has felt shy and awkward on occasion. One of the best ways to overcome self-consciousness or get past your feelings of shyness at social gatherings is to focus on the people around you. If you can remember that other people might also be feeling awkward or shy, you might find the thought of speaking to them less overwhelming. The next time there is a social event you feel nervous about attending, you may want to try this exercise: Spend some time with your eyes closed and breathe deeply. When you feel ready, create your own zone of comfort by _ yourself surrounded in a warm white light that is protective yet accepting of others. Imagine people at the event being drawn to you because of the open and warm feelings that you are showing. When you arrive at the event, take a moment to spread this same light of loving acceptance to everyone around you. Smile and greet people warmly. Try going up to someone who is standing alone and introduce yourself. When you show acceptance and openness, people can't help but respond to you in kind. Focusing on how we can make other people at a social gathering feel at ease can help us forget about our own insecurities. The next time you attend a social gathering, invite people to join you in your zone of comfort that you have so lovingly and intentionally created. Let yourself enjoy being encircled in the warmth of their friendships. What is the text mainly about?
