In China, more and more middle school students are getting shorter sleeping time than before. Most students sleep less than nine hours every night, because they have much homework to do. Some homework is given by their teachers, and some by their parents. Also, some students don't know how to save time. They are not careful enough while they do their homework, so it takes them a lot of time. Some students spend too much time watching TV or playing computer games. They stay up very late. Some students have to get up early every morning on weekdays to go to school in time by bus or by bike. It may be a long way from home to school. Schools and parents should cut down some of the homework so that our children can enjoy more than nine hours of sleep every night for their health. For children, we should make best use of our time. When we have enough time for sleeping, we will find it much better for both our study and health. Some homework is given by their teachers, and some by _ .

You may have seen a talking parrot on a TV show, in a movie, or even in someone's home. The parrot has learned to copy sounds that people make. Birds are not the only animals that can copy the noises they hear. Dolphins, bats, and some apes also copy sounds. Now we can add elephants to this list of copycats. Dr. Joyce Poole is a zoologist. She studies the sounds of elephants. While she was in Kenya, she would hear strange noises made by Mlaika after sunset. Mlaika was a 10-year-old African elephant. Mlaika lived near a highway. Dr. Poole says, "I could not tell the difference between Mlaika's call and the distant truck noise." She and other scientists studied Mlaika's sounds. It turned out that Mlaika was copying the sounds of the trucks driving by. Why would Mlaika copy trucks that she heard going by on the highway? Animals that are able to copy sounds may enjoy practicing new sounds. When they are kept outside of their natural environment, they may copy unusual sounds. That may be why an elephant would copy the sound of a truck. "Mlaika was not the only copycat elephant," Dr. Poole says. Calimero is a 23-year-old male African elephant. He spent 18 years with two female Asian elephants. Asian elephants make chirping sounds (sounds made by birds) to talk with one another. African elephants usually do not make chirping sounds. But Calimero now does. He is copying his Asian elephant friends. Dr. Poole says that elephants need to form bonds with their family and friends. She says, "They make sounds to communicate with each other. When they are separated, they use sounds to keep in contact." Parrots, dolphins, humans, and elephants show that being a copycat is one way that animals and people make new friends and keep old ones. According to the passage, why do some animals like to be copycats?
[ "To keep in touch with nature.", "To please people and other animals.", "To make new friends and keep old ones.", "To avoid the danger from the outside world." ]
C. To make new friends and keep old ones.

A high school in Hiroshima City has been the first to do something with DNA in the world. Its students have won praise not only for doing this research but also for presenting their findings to groups of expert scientists. The school is one of the Super Science High Schools allowed by the Ministry of Education, Culture, Sports, Science, and Technology, where students are given an opportunity to study science at an advanced level. Here, students use the same type of hitech experimental laboratories as those found at universities. In these labs, they conduct experiments and research in new fields of study not found in textbooks. As part of this science course, the students, with the help of Hiroshima University, used a machine called sequencer , and over the course of a year and a half they succeeded in decoding the DNA. They then presented their results to academic groups. Achieving a world first might sound very wonderful, but the process of decoding the DNA involved very hard work. The students were also responsible for maintaining the equipment, and they had to read difficult research papers and put in extra study beyond their regular schoolwork. "Researchers need to work hard. The work was tiring, but the students worked toward their ambitious goal of achieving a world first. They have a great sense of achievement, and the number of students who hope to become biologists has increased," said Taruma Akinori, who is in charge of the science course. In addition to the results being added to the scientific community, the students' research paper will be translated into English and made available overseas. Moreover, the students have decided to take on a new challenge in DNA decoding. Up to a point, their success is due to _ .

Have you ever dreamed of visiting a planet in the Milky Way? While the trip sounds exciting, it would take years and years to reach the place that we are going to. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years. European researchers are now doing hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel come true," said Mark Ayer of the European Space Agency last month. What seems like science fiction is not completely impossible. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out soon. A major challenge is the fact that cells can be very simple systems, but body organs are far more complex . "It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia. Just like bears and frogs, the hibernation of human beings would cause a person's metabolism to lower so they would need less energy. Medical research, however, is just half of a space flight hibernation system. There is the challenge of designing a suitable protective place to live. Such a place would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor life functions and serve the physiological needs of the hibernator. According to Ayer, the six-person Human Outer Planets Exploration Mission to Jupiter's moon Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045. , . In a hibernating situation, a person needs _ .

A cancer-stricken British teenager said on Thursday she had been moved by messages of support from around the world after writing an online "Bucket List" of things she wanted to do before dying. Alice Pyne, 15, created an Internet blog in which she described her fight against a cancer of the white blood cells. "I've been fighting cancer for almost four years and now I know that the cancer is gaining on me and it doesn't look like I'm going to win this one," she wrote. For her list, at the site www. alicepyne. blogspot. com, she has included making everyone sign up to be a bone marrow donor , swimming with sharks, meeting boy band Take That and getting a purple iPad computer. Messages of support and offers of help quickly flooded her webpage and it became one of the most talked about subjects on Twitter. "Oh dear! And I thought that I was just doing a little blog for a few friends!" she wrote after her site attracted huge attention. "Thank you so much for all your lovely messages to me." Alice, who lives with her family in the northwest English town of Ulverston, said the manager of Take That had arranged for her to see the band after reading her blog.

Today, as in every other day of the year, more than 3,000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3,000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths due to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised. First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors beat that among female by nearly 10 percent . The statistic is reversing . Third, several recent studies have indicate high school _ have excessively high smoking rates, as much as 75 percent . Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking level among youth. By "dropout" the author means _

Meals at the family dinner table could be the key to preventing a generation of teenage girls from developing eating disorders . New research shows girls who regularly have family meals are much less likely to adopt extreme weight-control behaviors such as vomiting, and using diet pills. The research, published in the international journal Archives of Pediatrics and Adolescent Medicine, surveyed students aged 13 to 17 in 2003 and followed them up five years later. Regular family meals were found to have a protective effect regardless of the age, weight, socioeconomic status, dieting habit or relationship with the family. Belinda Dalton, director of the eating disorder clinic The Oak House, said eating with family helped "normalize" young people's relationship with food. "When teens are feeling that they are not managing, they turn to something that they can control and food is something available and accessible for them to control. Clearly, if they are sitting with their family on a regular basis, then their family can be more in control of their eating," Ms Dalton said. "It's about young people feeling connected within their family, and _ builds self-esteem and a sense of worth and works very actively against someone developing an eating disorder. An eating disorder expert, Kirsty Greenwood, said meal times were often difficult for sufferers. "It's typical that they feel very ashamed of their eating habits and often won't eat with other people. Perhaps it's because they haven't experienced the important of the family meal while growing up," she said. The study found eating regular family meals made no difference to the future eating habits of boys. The author writes this passage with the purpose of _ .

It was reported last week that developers could take photos from Apple mobile and Google Android devices without the phone owners knowing that the images were being taken. In Apple's case, developers can also obtain the location information for each photo. Senator Charles Schumer said in a telephone interview that his office had spoken with officials at both Apple and Google on Monday. "We asked them if they could find a way on their own to prevent Apple from having access to private information," Mr. Schumer said. "They were friendly and open to the idea that this ought to be changed." On Sunday, Mr. Schumer said that he planned to send a letter to the Federal Trade Commission asking the agency to investigate Apple and Google after the privacy concerns came to light. Claudia Bourne Farrell, an F.T.C. spokeswoman, said the agency had received the letter but she could not comment further. "It worries people to think that one's personal photos, address book, and who knows what else can be obtained and even posted online without permission," Mr. Schumer wrote in his letter to the F.T.C. "If the technology exists to open the door to this kind of privacy invasion , then surely technology exists to close it, and that's exactly what must happen." Mr. Schumer said if Apple and Google could not come to an agreement to fix the problem, then he would be forced to take the issue further. He said other companies had been willing to work with his office to fix issues. "I'm optimistic that we can get this changed without any regulation," he said. "If it's not changed, then we'll turn to the F.T.C., and if that doesn't work then we'llconsider legislative approach." The F.T.C. has warned companies to try to be more vigilant in their efforts to protect consumers when it comes to privacy. The senators spoke with officials at both Apple and Google _

He has climbed a high mountain, raced the 24-hour motorcycle track in France and even, walked from Tokyo to Kyoto, a distance of 500 km. Now Evolta, Panasonic's 7-inch Humanoid Robot is getting ready for his biggest challenge -- the Ironman Triathlon Championship in Hawaii. To compete in this exhausting contest, the green & white robot which is small enough to fit on a human palm, will have to swim 2.4 miles in the rough ocean, bike 112 miles across the hot Hawaiian desert and, run a full marathon distance of 26.2 miles in the painfully hot weather. Given that he is so tiny and powered by rechargeable batteries of Panasonic, he will be allowed some freedom in the way he competes. For one, he will be starting the race on October 23rd, 2011, three weeks following the real event and, while human competitors have at most 17 hours to complete the triathlon, Evolta will be given 7 days, during which his only "breaks" will be to recharge his batteries. The biggest difference however, will be that unlike a single human body doing all three races, there will be three different "Evolta" robot bodies competing -- each built for the specific race. Evolta the swimmer will be equipped with special arms to swim forward. Evolta the biker, will be on a little two-wheeler with training wheels, while Evolta the runner, will be fixed on what looks like a wheel. In spite of all these advantages, the robot's creator Tomotaka Takahashi believes that the race will be a huge challenge -- not only will Evolta have to battle the wind and sun, but also, small road obstacles that humans just step over. The water will be even worse thanks to the strong waves, tides and ocean winds. But if he does complete it, Evolta will add another feather in his cap and just prove the already well-known fact that Panasonic's rechargeable Evolta batteries are indeed the "world's longest-lasting batteries"!

Women should not drink any alcohol during pregnancy. A report released by NICE says. It says if they must drink, they should not do so in the first three months and should limit to one or two ounces once or twice a week afterwards. It replaces previous guidance of saying small daily amounts were fine. NICE decided to tighten its guidance partly because of the concern that people are now drinking more than in the past. Previous draft guidance suggested women should drink an ounce of alcohol a day once they were past the first three months of pregnancy. The Department of Health in England changed its guidance last year, calling for no drinking while pregnant or while trying to get pregnant. Drinking heavily in pregnancy can cause fetal alcohol syndrome , which can leave children with features like small heads, widely spaced eyes and behavior or learning problems. The experts said there was no evidence that several ounces once or twice a week would do any harm to the baby but could not categorically rule out any risk. National Childbirth Trust agreed women should limit their drinking during pregnancy. "Pregnant women who have had a few drinks often worry a great deal about whether they have harmed their baby. In general, it is believed that if a light infrequent drinker, in good health, drinks to the point of drunkenness on one occasion, the risk to her baby is small." NICE also made a number of other recommendations for the care of women in the UK who were pregnant or planning to get pregnant. It said vitamin D and folic acid supplements should be offered by health staff to help avoid conditions such as rickets and spina bifida . Officials also called for local health officials to ensure equal support plans where mothers encourage new parents to breastfeed are set up. NICE also called for improvements in the care of pregnant women with diabetes. About 20;000 pregnancies each year are affected by diabetes and, therefore, carry, higher risk of miscarriage and still birth. The guidance said women should get access to advice and support, in particular to achieve good blood sugar control before they get pregnant. What is the advice made by the Department of Health on drinking alcohol during pregnancy?
[ "Little in the first three months and a gradual increase afterwards.", "An ounce a day after the first three months.", "No drinking for pregnant women.", "Those who drink regularly need not worry about the harm to their babies." ]

It takes two to duet , and one question for scientists is how these coordinated performances arise -- in birds. Are they the result of cooperation, a way in which one pair signals to others that they've got it together? Or are they the result of conflict, evolving to avoid one partner's song interfering with the other's? A study of duetting in Peruvian warbling antbirds suggests that it might be a little of both, and that context is everything. Joseph A. Tobias and Nathalie Seddon of the University of Oxford show in Current Biology that sexual conflict can cause the female of a pair that normally cooperates to "jam" the male's song by singing over it. The researchers exposed antbird pairs to recorded songs of other antbirds and monitored the songs the pairs produced. In one experiment, they played the songs of an intruding pair. In this case, the resident pair "both are likely to lose their territory, so both should cooperate," Dr. Tobias said. And they do. They produce a coordinated duet that in effect tells the intruders to keep away. But when the researchers played the song of a single female, the pair behaved differently. "You'd expect the resident female to be highly motivated to defend her position in the partnership," Dr. Tobias said. And that's what occurs. The male sings its heart out, flirting with the single female, and the female of the pair does its best to interfere with the song by singing over it, apparently to make her mate less attractive to the other female. "It's clear that the male doesn't like what she's doing," Dr. Tobias said. The behavior "breaks up what is otherwise a very cooperative situation into a more complicated signal," he added. It's the first evidence of this kind of signal jamming among pairs, Dr. Tobias said. And in that it leads the male to alter its song to avoid the female's interfering notes, it shows that this kind of conflict could, over a long period, drive the evolution of coordinated song. What is the key factor of antbirds' duet?

Conservationists have unveiled plans to preserve and protect the world's most important species of coral, in a response to increasing threats that they say will lead to "functional extinction" within decades. Led by scientists at the Zoological Society of London, the Edge Coral Reefs project has identified 10 coral species in most urgent risk of becoming extinct.The scientists say that reefs are under pressure from a variety of threats including rising sea temperatures due to climatic instability, increased acidity , overfishing and pollution. The Edge plan, which focuses on the most evolutionarily distinct and globally endangered species , will take a regional approach to conservation.This means focusing on the "coral triangle" around the Philippines, the West Indian Ocean around the Mozambique channel, and in the Caribbean channel. "Coral reefs are threatened with functional extinction in the next 20-50 years, due predominantly to global climatic instability," said Catherine Head, coordinator of the reefs project."In these regions, we'll be supporting and training in-country conservationists to carry out research and implement targeted conservation actions," she said."Their projects will last initially for two years.We provide them with a whole host of tools to carry out their projects including funding and intensive training." She added. Coral reefs are the planet's most diverse marine ecosystem , known as the rainforests of the oceans.Despite taking up under 0.2% of the ocean floor, they provide food and shelter for almost a third of all sea life.If we lose the ecosystems, we lose not only the biodiversity , but we also lose the capability of people to obtain income and food from coral reefs. Climatic instability, which leads to rising sea temperatures, causes corals to bleach.Bleaching occurs when sea temperatures rise and this causes the coral tissue to expel their symbiotic algae called zooxanthellae - these are what give the coral their colour.Bleached corals often die if the stress continues.Among the 10 species chosen to start the Edge project are the pearl bubble coral, a food source for the hawksbill turtle, and the Mushroom coral, which supports at least 15 brightly colored fish.

Hot yoga is not terribly different from regular yoga. You will do the same poses. However, the catch is that the temperature will be at least 100 degrees Fahrenheit and sometimes higher. The heat is what makes this type of yoga not for everyone. Regardless of your overall health, talk to your doctor before taking a hot yoga class and let your doctor know that you plan to take one. Due to a condition that is greatly worsened by temperature extremes, I'm an example of someone who can't do this form of exercise. I can do regular yoga, but the 100 degree Fahrenheit would be severely uncomfortable and possibly dangerous to me. The climate is said to help with muscle flexibility and you will sweat like there is no tomorrow -- which is believed to force out more toxins .It is important to keep in mind that even if you are in good health, the high temperature can take some getting used to. You may want to start a shorter class and work your way up. You will be sweating greatly in hot yoga temperature. Drink plenty of water before, during and after your class. It is also important to pay attention to your body. If you are feeling very tired, it is time to sit down and get some water. You should also remove yourself from the hot environment, but not into a very cold environment. For example, just go into hallway -- a place that has a normal temperature and start to drink some water. Things like heat stroke are possible with this type of yoga. These issues are most often seen in those over 60 years of age, but younger people with chronic health problems are also at risk. Anyone can fall victim to heat stroke. Children are also especially vulnerable to heat stroke, so leave the kids at home while you attend your yoga class. If you ever start to feel had during class, immediately stop and tell your instructor so that he or she can offer you help. Don't try to finish the class. Have a physical checkup before taking the hot yoga class _ .

Stephen Hawking was born in Oxford, England, on January 8, 1942. At the age of 17, he entered University College, Oxford. He wanted to study mathematics, but took up the study of physics when math was unavailable. He received a Ph.D. in physics despite being diagnosed with Ameliotrophic Lateral Sclerosis while at Oxford in 1963. In 1985 he became ill with pneumonia , and since then has required 24-hour nursing. Dr. Hawking's determination, along with the help of his family and associates, has allowed him to continue to work. In 1970 he began studying black holes. His research led him to predict that black holes send out radiation in the X-ray to gamma-ray range of the spectrum . In the 1980s he returned to an earlier interest, the origins of the universe. He has co-authored many publications, such as 300 Years of Gravity and The Large Scale Structure of Space time. Dr. Hawking has also written books such as A Brief History of Time, Black Holes and Baby Universes and other Essays, The Universe in a Nutshell and others. He continues to give lectures, despite having been unable to speak since 1985, with the aid of a speech synthesizer and a portable computer.

It has been known that the octopus has many special skills, such as using hard shells for mobile homes and protection, disabling their suckers, plotting escapes, and even predicting World Cup soccer game outcomes. Can't we say it is a mysterious creature? While all these talents are impressive, they pale compared to its ability to "disappear" from plain sight. Researchers have long known that this is possible because of the presence of the organs under their skin, which expand or contract to produce a series of color1s, patterns and even skin textures in just milliseconds. Scientists had always believed that such a reaction was directed by a signal from the octopus's large, human-like eyes or brain. But a recent report published in the Journal of Experimental Biology by researchers from the University of California at Santa Barbara, indicate that the animal does not have to wait for a signal from its eyes or brain. It can "see" the light with its skin! UCSB doctoral student Desmond and Professor Todd said they have seen reports about octopus skin changing color1s in response to light with no signal from the eye or brain. However, there had been no follow-up to find out why this was the case and the two decided to see what they could uncover. They began by taking skin samples from a couple of California octopuses and exposing them to color1s, ranging from violent to orange and found that their skin is equipped with the same light-sensitive protein as is found in the cells in the retina of the eyes. Thanks to these proteins, the octopus can "see" the light and react without having to wait for a signal from the eyes or brain, thus enabling it to begin the escape process. Another research by University of Maryland researchers discovered that cuttlefish and squid share the same talent. Thanks to these findings researchers now know that their skin color1 can be controlled by both. What is still not clear is how the two come together to manage the whole process. The doctoral student plans to get to the bottom of the mystery. What is the next aim of Desmond on octopuses?

The rise in smartphones among young people may be having a direct effect on how successful they become as adults. Research from the University of Nebraska-Lincoln has discovered the average university student checks their phones 11 times per lesson, and more than 80 percent believe this tech addiction is interfering with their learning. A quarter of students across five U.S states also blamed poor grades in exams specifically on the fact they used mobile devices when they should have been concentrating and revising - and these grades could determine the jobs they end up going into. Barney McCoy, an associate professor of broadcasting at the university, surveyed 777 students at six universities across five states about how they used digital devices in the classroom. The students were from UNL and the University of Nebraska at Omaha in Nebraska, Morningside College in Iowa, the University of North Carolina, the University of Kansas and the University of Mississippi. Around two thirds said they used phones, tablets and laptops for "non-classroom purposes" up to ten times during a typical university day, while 15 percent admitted this figure was closer to 30 times. Among the top reasons why students checked their devices so regularly were staying connected and fighting boredom, at 55 percent. Less than half said the devices were used for classwork. Texting was the most popular distraction technique at 86 percent, while 68 percent said they used their phones to check personal emails. Two thirds used social networks, 38 percent surfed the web and eight percent admitted to playing games when they should have been studying. Despite eight out of ten students admitting their devices were distracting, fewer than five percent considered it to be a "very big" distraction. "I don't think students necessarily think it's a big problem," said McCoy said. "They think it's part of their lives." "It's become automatic behavior on the part of so many people - they do it without even thinking about it." He continued, "They've got their laptops open, but they're not always taking notes. Some might have two screens open -- Facebook and their notes." The majority of the students think that using smartphones _ .

First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. It may save a life or improve certain vital signs including pulse, temperature, a clear airway, and breathing. In minor emergencies, first aid may prevent a victim's condition from turning worse and provide relief from pain. First aid must be done as quickly as possible. In the case of the seriously injured, a few minutes can make the difference between complete recovery and loss of life. First-aid measures depend upon a victim's needs and the provider's level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example, can lead to permanent spinal injury and paralysis . Despite the variety of injuries possible, several principles of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious, should be reassured that medical aid has been requested, and asked for permission to provide any first aid. Next, assess the scene, asking other people or the injured person's family or friends about details of the injury or illness, any care that may have already been given, and pre-existing conditions such as diabetes or heart trouble. The victim should be checked for a medical card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim. First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for evaluating a victim's condition is known by the acronym ABC, which stands for: A---Airway: is it open and clear? B---Breathing: is the person breathing? Look, listen, and feel for breathing. C---Circulation: is there a pulse? Is the person bleeding extremely? Check skin color and temperature for additional indications of circulation problems.

DNA is the whole "map" of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own. People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called "genes" in our body. In 1953, two scientists, Watson and Crick, found out that genes are really messages. They're written in the DNA with a special language. In 1961, another two scientists found the first "word" that they could understand in that language. It shows how DNA tells the cell to build its parts. So far, scientists have found all the words in the DNA map, but we still don't understand what they all do. By understanding what just one "word" means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.

Energy is very important in modern life. People use energy to run machines, heat and cool their homes, cook, give light, and transport people and products from place to place. Most energy comes from fossil fuels--petroleum, coal, and natural gas. However, burning fuels causes pollution. Also, if we don't find new kinds of energy, we will use up all the fossil fuels in the twenty-first century. Scientists are working hard to find other kinds of energy for the future. What might these sources of energy be? Energy from the wind All over the world, people use the power of the wind. It turns windmills and moves sailboats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy. Energy from water When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. In Brittany, France, for example, waterpower produces enough energy to light a town of 40,000people. Waterpower gives energy without pollution. However, people have to build dams to use this energy. Dams cost a lot of money, so water energy is expensive. Energy from the earth There is heat in rocks under the earth. Scientists use this heat to make geothermal energy. San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is possible only in a few places in the world. Energy from the sun Solar panels on the roofs of houses can turn energy from the sun into electricity. These panels can create enough energy to heat an entire house. Solar power is clean and there is a lot of it in sunny places. But when the weather is bad, there is no sunlight for energy. What is the writer's opinion about the energy?

Young children whose mothers talk with them more frequently and in more detail about people's thoughts and feelings tend to be better at taking another person's perspective than other children of the same age. That's what researchers from the University of Western Australia found in a new study published in the journal Child Development. "Parents who frequently put themselves in someone else's shoes in conversations with their children make it more likely their children will be able to do the same," said lead author Brad Farrant. Researchers of the UWA's Telethon Institute for Child Health Research looked at the influence of how parents interact with their children to learn more about how people develop the ability to take another's perspective. The two-year study involved more than 120 Australian children aged between four and six, including children with typically developing language and others delayed in language acquisition . The children completed tasks which were designed to assess their language skills, ability to infer others' beliefs and use these to predict others' behavior, and their ability to shift flexibly between different perspectives. Among children with typically developing language, the researchers found that mothers who talked more often and in greater detail about people's thoughts and feelings -- commenting on how another person might react to a particular situation as well as their own feelings about the topic -- had children with better language skills and better perspective-taking skills. Children with delayed language acquisition were also delayed in their development of perspective-taking skills. This displays the role played by language as children develop the ability to take another's perspective. "Solving the many challenges that the world faces today requires us all to get better at taking the perspective of other people," said Brad Farrant. Which of the following is TRUE about the study?
[ "Over one hundred American children took part in it.", "All the children had delayed in language acquisition.", "The children in the study were around five years old.", "Mothers helped their children to complete the tasks." ]

Eat nuts, live longer. Researchers have found that those who eat a handful of peanuts every day significantly decrease their risk of dying from all causes compared to those who do not eat nuts. A new study concludes that all types of nuts seem to be protective. Researcher Ying Bao is with the Department of Medicine at Brigham and Women's Hospital and Harvard University Medical School in Boston, Massachusetts. She and her colleagues looked at the impact of nut consumption by analyzing two huge studies that began in 1980 - the Nurses' Health Study, which tracks the of more than 76,000 women, and 42,000 men enrolled in the Health Professionals Follow-up Study. Among the questions asked at the beginning of the studies was, 'how frequently do you eat nuts?' The information was updated every two to four years. Bao says the participants were followed for three decades. "What we observed is that people who eat more nuts are less likely to die over the next 30 years," said Bao. "So, for example, if a person eat(s) nuts once per day, that person has a 20 percent lower risk of dying." Bao says eating a handful of nuts five or more times per week was associated with a 29 percent reduced risk of dying from heart disease and an 11 percent lower risk of cancer death. A serving size is 28 grams. Nuts contain nutrients, including high quality proteins, vitamins and minerals, all of which have anti-cancer effects and may help protect the heart. Bao says researchers are planning studies to find out how nuts are beneficial to human health. The study on the health benefits of nuts was funded by the International Tree Nut Council Research and Education Foundation. About Bao's research, which statement is true?

Scientific Progress Most scientific progress is the result of careful consideration of work that has already been done. The wonderful world which lies before us today has been put up by hardworking men with clear heads and inventive mind, and these who follow them along life's road will improve on their efforts. It is sometimes necessary to question and even to disbelieve some of the statements made by experts. Action or experiment can often end an argument or achieve a breakthrough. When men were wondering whether it was possible to reach India by sailing westwards from Europe, and whether there was any land on the other side of the Atlantic Ocean, Christopher Columbus decides to act. He gathered some men, invited them to go on board his three ships, and set out across the dangerous waters of the Atlantic Ocean. He was successful in finding land, but it was not India. The result of his action was that the arguments came to the end. Any young man who wishes to do research must be courageous enough to question old beliefs and do some original thinking about them. Although we seem to know so much, there are many things we don't know. Even when we pull an atom to pieces, we do not really know what the pieces are, we often do not reach the reality behind what we discover, and the more we learn, the better we realize our ignorance.

Modern science suggests that a healthy lifestyle matters much to how long you can live and how well you live. Here are some tips for you to form a healthy lifestyle. Keep a scientific diet. Keep in mind that sugar can be removed from our diet completely. Over intake of sugar is one of the main reasons for getting fat. Over intake of protein or fat and low intake of fiber can also lead to getting fat. We need only a few grams of protein every day to keep our body in order. Like rain to crops, not the more the better. Be always in a good mood. There is a relation- ship between the mood and health. A good mood keeps you in high spirits. Thanks to the internet, we can enjoy and learn much without going out. Take a look at some online shops and pick up some bargains, enjoy music and movies and chat with some good friends. Just keep happy. Enough sleep. Two studies show the reasons why teens and adults don't have enough sleep. With teens, a major reason is mobile phone use; with adults, it's work. Meanwhile, a third study of young children shows that a lack of sleep in early life may lead to serious problems in future. Everyone needs at least 8-hour sleep to recover from tiredness and the hurt caused by hard work in the daytime. Proper exercise. Do exercise to keep away from fatness. Because of the quick pace of modern life, you don't have time to do exercise every day, but at least three times a week and 45 minutes each time. The main reason why teenagers don't have enough sleep is that they _ .

The monitor "watches" deceleration (=slow down) and distance from a light - and "guesses" which cars are likely to break the Highway Code. Most importantly, the software can provide two seconds' warning if someone else is about to shoot across a crossroads - enough time for other drivers to hit the brakes. Jonathan How, the Professor of Aeronautics and Astronautics at MIT, says "smart" cars of the future may use the system to help drivers foresee and avoid potential accidents. The researchers tested the algorithm on data collected from an intersection in Virginia, finding that it accurately identified potential violators within a couple of seconds of reaching a red light -- enough time, according to the researchers, for other drivers at an intersection to be able to react to the threat if alerted . Compared to other efforts to model driving behavior, the MIT algorithm brought fewer false alarms, an important advantage for systems providing guidance to human drivers. The researchers report their findings in a paper that will appear in the journal IEEE Transactions on Intelligent Transportation Systems. We can learn from the passage that the algorithm _ .

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the greenhouse gases they send out, which is thought to be responsible for global warming. Thanks to special bacteria in their stomachs, kangaroo flatulence contains nomethane and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas. While the usual image of greenhouse gas pollution is a billowing smokestack pushing out carbon dioxide, farm animals' passing wind contributes a surprisingly high percentage of total emissions in some countries. "Fourteen percent of emissions from all sources in Australia is from enteric methane from cattle and sheep," said Athol Klieve, a senior research scientist with the Queensland state government. "And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent," he said. Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers. But it will take researchers at least three years to isolate the bacteria, before they can even start to develop a way of transferring it to cattle and sheep. Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos. And about 20 percent of health-conscious Australians have eaten the national symbol already. "It's low in fat, it's got high protein levels and it's very clean in the sense that basically it's the free-range animal," said Peter Ampt of the University of New South Wales's institute of environmental studies.

One of the world's richest men has taken a close interest in one of man's most basic functions: visiting the toilet.Bill Gates's charitable organization, the Bill and Melinda Gates Foundation, is looking for inventors to design the loo of the future, which, they hope, would improve sanitation for millions of people around the world. So, what's wrong with the traditional flush toilet? Firstly, it wastes a huge amount, of potential drinking water.Secondly, they are more likely to cause pollution.This is a real problem in many areas of the developing world, where, according to United Nations estimates, unsafe sanitation causes half of all hospitalizations.Younger people are particularly at risk.Illnesses which cause diarrhea are responsible for the deaths of about 1.5 million children a year.Finally, standard lavatories simply aren't practical in remote areas. The challenge set by Bill Gates was to come up with a _ which works without running water, electricity or aseptic tank.It also needed to operate for less than 5 cents.28 designs were displayed at the recent Reinvent the Toilet Fair.in Seattle, USA.Among them was one which turned human waste into electricity using microwaves, another which converted human waste into charcoal, and yet another which used urine for flushing. But the winner was a solar-powered design which generated hydrogen gas and electricity.The team from the California Institute of Technology(CIT)picked up a prize of $ 100,000. But clearly Bill Gates doesn't feel he's _ .After the Seattle event he said, "We, couldn't be happier with the response we've gotten," Gates has even pledged $370 million more to the future toilet project.They hope to field test more, prototypes over the next three years.

People are being lured onto Facebook with the promise of a fun, free service without realizing they're paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages. Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth. The biggest problem, however, is that the company keeps changing the rules. Early on, you keep everything private. That was the great thing about facebook--you could create your own little private network. Last year, the company changed its privacy rules so that many things-- your city, your photo, your friends' names--were set, by default to be shared with everyone on the Internet. According to Facebook's vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a "less satisfying experience". Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they're online connecting with their friends? The privacy issue has already landed Facebook in hot water in Washington. In April. Senator Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set guidelines for social-networking sites."I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them," Schrage admits. I suspect that whatever Facebook has done so far to invade our privacy, it's only the beginning, which is why I'm considering deactivating my account. Facebook is a handy site, but I'm upset by the idea that my information is in the hands of people I don't know. That's too high a price to pay. What does the author say about most Facebook users?
