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. According to the author, the deaths among youth are mainly caused by _ .

Do your parents smoke? Where do they smoke - outside, at work or at home when you are around? According to a survey published in the journal Academic Pediatrics, an alarming number of US parents are still risking their children's lives by smoking in front of them. Half of all children aged 6 to 19, even those with asthma , have been exposed to second-hand smoke in the country, reported Reuters. "It's well known that smoking kills, but many smokers still don't realize the damage their smoke causes to those around them," Dame Sally, Chief Medical Officer for England, was quoted by the Independent as saying. Tobacco smoke contains more than 7,000 chemicals, hundreds of which are poisonous. About 70 of them can cause cancer, not to mention other diseases, according to the US Centers for Disease Control and Prevention. What's most scary is that there is no safe level of contact with second-hand smoke---even "low-level" exposure can be harmful to one's health. And "low-level" means when a parent or family member smokes in another room or even outside. While second-hand smoke can be harmful to people of all ages, children face a greater risk than adults: they have smaller lungs; they breathe more quickly; and they have less developed immune systems. Also, young children have little control over their surroundings. Babies can't move to another room because the air is smoky. They depend on the adults in their lives to make sure that their environments are safe. Recent years have seen second-hand smoke exposure drop---but for adults rather than kids, because policies have been started around the world to ban smoking in public places such as offices, bars and restaurants. However, "Children tend to be exposed to second-hand smoke in homes and cars, and these places are not included in most laws and policies," Amy Ferketich, a researcher at The Ohio State University, US, told Reuters. So what can we do to limit children's exposure to second-hand smoke? Parents should stop smoking for good. But if they can't, they should never smoke---or let others smoke---around their children. The drop of second-hand smoke exposure in recent years _ .

A Train Floating On Air A train that floats on air? It's not magic--it's magnets .And it's close to reality. In Virginia USA the fall of 2002, a train with no wheels traveled on air and carried college students across their campus.In Japan, a whisper-quiet railway engine hovered and raced at 350 miles per hour using magnets and electricity as the power.And in China, a magnet train line linked Shanghai with nearby Pudong Airport. These trains use magnetic levitation technology, "maglev" for short. They use the same rules as the magnets you pick up at home or school: opposite poles of magnets attract each other, and like poles _ each other. How does it work? Powerful magnets on the bottom of the train repel magnets on the track, which is actually just a magnet-filled guiding way. With a magnetic field of sufficient force, the train will go hovering on air, which seemed impossible to us in the past. When an electrical current is sent through the track, the train moves. Turn the current backwards and the train slows down. Maglev doesn't rely on the friction of wheels on track, so it can climb a much steeper hill than a traditional train. And it can travel easily in snow and ice, something that could bring normal trains to a screaming stop. This passage is about _ .

Everybody is happy as his pay rises. Yet pleasure at your own can disappear if you learn that a fellow worker has been given a bigger one. Indeed, if he is known as being lazy, you might even be quite cross. Such behavior is regarded as "all too human", with the underlying belief that other animals would not be able to have this finely developed sense of sadness. But a study by Sarah Brosnan of Emory University in Atlanta, Georgia, which has just been published in Nature, suggests that _ , as well. The researchers studied the behaviors of some kind of female brown monkeys. They look smart. They are good-natured, co-operative creatures, and they share their food happily. Above all, like female human beings, they tend to pay much closer attention to the value of "goods and services" than males. Such characteristics make them perfect subjects for Doctor Brosnan's study. The researchers spent two years teaching their monkeys to exchange tokens for food. Normally, the monkeys were happy enough to exchange pieces of rock for pieces of cucumber. However, when two monkeys were placed in separate and connected rooms, so that each other could observe what the other is getting in return for its rock, they became quite different. In the world of monkeys,grapes are excellent goods (and much preferable to cucumbers). So when one monkey was handed a grape in exchange for her token, the second was not willing to hand hers over for a mere piece of cucumber. And if one received a grape without having to provide her token in exchange at all, the other either shook her own token at the researcher, or refused to accept the cucumber. Indeed, the mere presence of a grape in the other room (without an actual monkey to eat it) was enough to bring about dissatisfaction in a female monkey. The researches suggest that these monkeys, like humans, are guided by social senses. In the wild, they are co-operative and group-living. Such co-operation is likely to be firm only when each animal feels it is not being cheated. Feelings of anger when unfairly treated, it seems, are not the nature of human beings alone. Refusing a smaller reward completely makes these feelings clear to other animals of the group. However, whether such a sense of fairness developed independently in monkeys and humans, or whether it comes from the common roots that they had 35 million years ago, is, as yet, an unanswered question. According to the passage, which of the following statements is TRUE?
|
[
"Only monkeys and humans can have the sense of fairness in the world.",
"In the wild, monkeys are never unhappy to share their food with each other.",
"Women will show more dissatisfaction than men when unfairly treated.",
"Monkeys can exchange cucumbers for grapes, for grapes are more attractive."

One of the tough things about being a high school student is that you never seem to get enough sleep at night, which often leaves you nodding off during classes. "The best amount of sleep to get is about seven and a half to eight hours," Peter Venn at Queen Victoria Hospital, UK, told The Telegraph. Spending either less than six or more than nine hours in sleeping puts your health at risk. A popular solution to a lack of sleep at night is to take a "power nap" during the day, but does this work? Generally speaking, it can be beneficial. Research shows that a nap in the middle of the day --even a brief one as short as five or 10 minutes ---can clear your mind and leave you with increased energy and improved productivity , according to Forbes. However, as refreshing as it might be, if you are getting adequate sleep at night, taking a power nap isn't such a wise choice. The reason is that sleeping during the day can interfere with your body's biorhythms . The brain gets used to going to bed at roughly the same time each night and getting up at the same time each day, and you don't want to disturb this routine. One more thing to keep in mind is that a power nap should never be used as a replacement for a good night's sleep. "Twenty minutes of power nap during the day is not like a tablet which will definitely work," Rahul Mukherjee, an Indian sleep specialist, told The Telegraph. "An hour's sleep before midnight is worth a couple of hours' sleep after midnight." Why can taking a power nap in the middle of the day be beneficial?
|
[
"Because it refreshes people and thus improves their productivity.",
"Because it is good for our body's biorhythms.",
"Because it takes little time but always works well.",
"Because it can be used as a replacement for a good night's sleep."

Amy Chua may well be very _ . What kind of a mother will drag her then 7-year-old daughter's dollhouse out to the car and tell her that it is going to be donated if the poor kid doesn't master a difficult piano composition by the next day? What kind of a mother will inform her daughter that she is nothing but "garbage"? And what kind of mother will believe, as Chua tells readers, that "an A- is not always a good grade"? The only activities her children should be permitted to do are those in which they can eventually win a medal, which must be gold. What kind of a mother she is? Why, a mother who is raising her kids in the typical Chinese way, rather than the Western way. In her new book, Battle Hymn of the Tiger Mother, Chua tells her adventures in Chinese parenting, and -- so _ as she may be -- she is also mesmerizing . Chua's voice is that of a happy, knowledgeable serial killer -- think Hannibal Lecter -- who's explaining how he's going to cut his next victim, as though it's the most self-evidently normal behavior. There is another attractive aspect of Battle Hymn of the Tiger Mother. There are methods to Chua's madness, enough method to stir up self-doubt in those readers who support the more educating parenting styles. It is trusted that Battle Hymn of the Tiger Mother is going to be a book club and parenting blog phenomenon; there will be fevered debate over Chua's tough love strategies, which include unchangeable bans on such Western indulgences as sleepovers, play dates, and any after class activities except practicing musical instruments, which must be limited between the violin or the piano. The back story to Chua's book is this -- she is the daughter of a couple of Chinese immigrants and is now a professor at Yale Law School and the author of two best-selling "big-think" books on "free-market democracy" and "the fall of empires". When Chua married her husband, her fellow Yale law professor and a novelist Jed Rubenfeld, they agreed that their children would be brought up in "the Chinese way," in which punishingly hard work, enforced by parents produces excellence; excellence, in turn, produces satisfaction. The success of this strategy is hard to debate. Their older daughter is a piano talent who played at Carnegie Hall when she was 14 or so. The second, a more rebellious daughter, Lulu, is a gifted violinist. Chua rode the girls hard, making sure they practiced at least three hours a day even on vacations, when she would call ahead to arrange access to practice in hotel lobby bars and basement storage rooms. Chua also rarely refrained from criticizing her daughters. She explains: Chinese parents can do things that would seem unimaginable to Westerners. Chinese mothers can say to their daughters, "Hey so fatty, lose some weight." By contrast, Western parents have to tiptoe around the issue, talking in terms of "health" and never ever mentioning the f-word, and their kids still end up in treatment for eating disorders and negative self-image. ... Western parents are concerned about their children's minds. Chinese parents aren't. They assume strength, not weakness, and as a result they behave very differently. From the passage we can learn that Chua's way of parenting is _ .

They spend more than ten hours a day cooking, cleaning the house, getting children ready for school and helping with homework. Cooking takes up about one hour and nine minutes a day. Doing the laundry takes about 61 minutes. Mothers also spend about 55 minutes getting children ready for school, about 53 minutes putting them to bed and about 47 minutes helping with homework. However, 30% of those mothers with children under 16 get less than six hours' sleep at night. 83% are not happy because they have less than an hour of their own time every day. Only 17% are happy with this kind of life. In the survey, mothers spend about 70 hours a week _ .

Perfect grades, perfect bodies, perfect friends. Welcome to Generation Supergirl - the young women who are supposed to have everything. Unlike their grandmothers, they don't have to fight for their right to be heard. Unlike their mothers, they are confident they can have the career without sacrificing the home life. Record numbers of them are achieving top grades, heading to the best universities and on to great jobs. But are all these opportunities making them happy? According to a new book, Supergirls Speak Out: Inside the Secret Crisis of Over-Achieving Girls, the answer is no. As the book's 21-year-old author, Liz Funk, explains: Their search for perfection has turned them into stressed-out women who are at risk of eating disorders, depression and even suicide . So why have so many teenage girls come to the conclusion that anything short of perfection is failure? Stephen Hinshaw, professor of psychology at the University of California, Berkeley, believes that they are suffering from the weight of expectations: society's, their parents', and most crucially , their own. They are constantly bombarded by "perfect" celebrity(, ). Articles about how to have the perfect career and perfect life appear to be everywhere. So it is hardly surprising that increasing numbers of young women are unable to cope and are unsure of just who they are. "Many teenage girls have no intrinsic sense of their own worth," says Funk. "Instead, they see themselves in terms of how they look, how they are seen, what they've achieved." Teenage girls believe that they must be all things to all people. They must be good at "girl" stuff-cultivating relationships and being beautiful - as well as being good at "guy" stuff - competing aggressively both at college and in the workplace. According to Funk, teenage girls need to recognize that "you don't have to be successful at everything." "Young women should take time for themselves and think about what matters to them, or enjoy life for what it is," she said. What can we infer from the article?

In the animal kingdom, weakness can bring about aggression in other animal. This sometimes happens with humans also. But I have found that my weakness brings out the kindness in people. I see it every day when people hold doors for me, pour cream into my coffee, or help me to put on my coat. And I have discovered that it makes them happy. From my wheelchair experience, I see the best in people, bur sometimes I feel sad because those who appear independent miss the kindness I see daily. They don't get to see this soft side of others often. We try every way possible to avoid showing our weakness, which includes a lot of pretending. But only when we stop pretending we're brave or strong do we allow people to show the kindness that's in them. Last month, when I was driving home on a busy highway, I began to feel unwell and drove more slowly than usual. People behind me began to get impatient and angry, with some speeding up alongside me, horning or even shouting at me. At the moment I decided to do something I had never done in twenty four years of driving. I put on the car flashlights and drove on at a really low speed. No more angry shouts and no more horns! When I put on my flashlights, I was saying to other drivers, "I have a problem here. I am weak and doing the best I can." And everyone understood. Several times, I saw drivers who wanted to pass. They couldn't get around me because of the stream of passing traffic. But instead of getting impatient and angry, they waited, knowing the driver in front of them was in some way weak. Sometimes situations call for us to act strong and brave even when we don't feel that way. But those are few and far between. More often, it would be better if we don't pretend we feel strong when we feel weak or pretend that we are brave when we are scared. The author feels sad sometimes because _ .

Online Communication In an age when technology moves faster than most can keep up with, a small group of people still remain in the time of old-fashioned letter. Frankly speaking, I was once certain that traditional letters could never be replaced by other means of communication. But a story about online communication changed my mind. An old man, who suffered a lot from Parkinson's disease, was not able to talk clearly and could hardly write his name. Living totally alone, he managed to keep in touch with nearly all the members of his family. How did he achieve this? He clicked out words on his computer keyboard. I, therefore, managed to get an E-mail box as soon as the opportunity came. My life changed. E-mail, and all online communication, is something truly different. It has capabilities that few other products can match. E-mail is convenient. It takes less time with its fast speed and 24-hour connection. The slow postal service is no match. If you wouldn't want to have a face-to-face talk with your manager, you might talk with him through E-mail even if you are in the same office. Naming all the good things about online communication is not easy. But wait. E-mail can be inconvenient. It can waste time and energy. Just think what may happen when you take a short vacation and return to find your e-mail box filled with 200 unread messages. You could easily spend half a day clearing _ ads. Then, online communication will keep us staying at our computer while it connects us to distant strangers. Once we throw ourselves into the machine, we may forget the human touches we once held so dear. I'm sure there is and always will be a place for the old-fashioned letter, phone call, and face-to-face meeting... even in the world of modern communication. As I listen to the sound of the modem , I was excited at stepping out to the outside world but, at the same time, I sensed a loss of control over something valuable in my personal life. How did the sick old man keep in touch with his family members?

Many of us don't pay attention to the importance of eye care. It's said that if you take care of your body, then you can be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place. There are several causes leading to poor eyesight like not enough food, gene and aging . Televisions, computers and reading are also the causes of having poor eyesight. If you happen to work in front of the computer, it is best to take a rest every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful thing. For example, sunglasses are not just fashion but they can also serve as a great way to protect your eyesight from _ .

ELMONT, N. Y. (AP)---Elmont High School senior Harold Ekeh had a plan--he would apply to 13 colleges , including all eight Ivy League schools, figuring it would help his chances of getting into at least one great school. It worked, And then some, The teenager from Long Island was accepted at all 13 schools, and now faces his next big test: deciding where to go. "I was stunned, I was really shocked, "Ekeh told The Associated Press during an interview Tuesday at his home near the Belmont Park racetrack, his four younger brothers running around. He found out last week he had been accepted to Princeton University. That made him eight for eight in the Ivy League--he had already been accepted to Yale University , Brown University, Columbia University , Cornell University , Dartmouth College, Harvard University and University of Pennsylvania. His other acceptances came from Johns Hopkins University, Massachusetts Institute of Technology, New York University, Stony Brook University and Vanderbilt University. "We are so proud of him, " said his mother , Roseline Ekeh."Hard work, dedication, prayer brought him to where he is today. " Born in Nigeria, Harold was eight years old when his parents brought the family to the United States. "It was kind of difficult adjusting to the new environment and the new culture, " he said. But he saw his parents working hard, "and I took their example and decides to _ He referenced that effort in his college essay, writing, "Like a tree, uprooted and replanted, I could have withered in a new country surrounded by people and languages I did not understand. Yet, I witnessed my parents persevere despite the potential to give in. I faced my challenges with newfound zeal; I risked insults, spending my break talking to unfamiliar faces, ignoring their sarcastic remarks. " Harold "is tremendously focused in everything he does." said John Capozzi, the school's principal, "He's a great role model. All the students and faculty are so proud of him. " Harold is the second Long Island student in as many years to get into all eight Ivies. Last year, William Floyd High School's Kwasi Enim chose to go to Yale. Harold, who has a 100. 51 grade-point average and wants to be a neurosurgeon, said he was leaning toward Yale, and had heard from Enin, offering congratulations. Like Enin, he's likely to announce his college choice at a press conference later this month. The deadline to decide is May 1. What can we infer from this passage?

Early to bed and early to rise makes a man healthy, wealthy and wise. This is an old English saying. It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever. Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours' sleep every night. If you do not go to bed early, you can not have enough sleep. Then you can not think properly and you can not do your work properly. You will not be wise and you may not become wealthy! Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us to sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong. Exercise helps the blood to move around inside the body. This is very important. Blood takes nutrition to all parts of our bodies. The brains in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better! Our bodies also need air to breathe. Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy. It's important for people to have enough sleep. If not, they _ .

Last March, the H7N9 virus hit Shanghai, Anhui, Jiangsu, Zhejiang and so on. It seemed that most people who were infected with H7N9 had the common flu . Some people suffered from a fever or a cough. Don't be afraid--it's not easy to be infected with the virus. Here is some advice to help you protect yourself when it comes. Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet, and after you touch animals, because your hands may carry viruses. Cover your nose and mouth. When someone sneezes or coughs, flu viruses can travel as far as one meter through the air, so you'd better stand a proper distance while talking to someone who has a cold. And always cover your mouth and nose with a piece of paper when you sneeze or cough, and then clean your hands. Wear a mask . Some doctors say that masks can stop the flu as much as 80%, but if you don't wash your hands often, it's no use wearing a mask. And it's necessary to wear the mask in the groups of people. Do sports often. Exercises will help make your body strong enough to resist the virus. When did the H7N9 virus hit Shanghai?

*New labels to show calories The US government ruled that all food establishments should put the calorie information of their foods on their menus. Within a year chain restaurants, like fast food KFC, will have to say clearly on their menus how many calories their fried chicken wings, fries, and other items contain. Amusement parks, movie theaters and supermarkets will also have to follow the rules. The move is designed to fight against the problem of obesity in the US. * _ leading to world problem The entire world is facing this problem: antibiotic resistance. And the resistance will lead to the deaths of 10 million people across the world by 2025, predicted a new report released by the UK government. Antibiotics are used to destroy or slow the growth of harmful bacteria in our bodies. But overuse and misuse of them can encourage bacteria to develop new ways of overcoming antibiotics, which makes it increasingly difficult for humans to fight diseases. * _ Australia is the world's most expensive destination for international students, according to a study done by Hong Kong and Shanghai Banking Corporation (HSBC). They have to spend an average of $ 42,000 ( about 258 ,000 yuan) a year to study at Australian universities. Singapore is not far behind, with an average yearly cost of $ 39,229, followed by the US at $ 36,564 and the UK at 35,045. However, Australia's education quality only ranks joint fourth with Canada, well below the US, the UK, and Germany. In addition, international students studying in Germany only have to pay about one-sixth the cost of studying in Australia. * New Games sports may be added The International Olympic Committee has canceled the 28-sportcap for future summer Olympics But each summer Games will still only be allowed 10, 500 athletes and 310 events. Countries that could host the games will discuss plans with the committee during a new invitation stage before bidding. They are also allowed to hold events outside their own countries and get financial support from the committee. No changes will be introduced for the 2016 Olympics in Rio de Janeiro, Brazil.

We can express our feelings and needs by using body language. Cats can do that too. The ways that cats use their tails to show their feelings and needs are interesting. Unlike dogs, which generally wave their tails to express good feelings, cats use their tails to send a lot of signals. When a cat waves its tail strongly from side to side, it may be a sign for us to leave it alone, or we may get scrathed . Throwing a little toy for the cat to play with can get it relaxed. When a cat holds its tail upwards with a slight move, it means the animal is very happy to see its owner. We all like to cuddle inside our bed, and cats do that thing, too. Much as little children like to wrap (......) their arms around their Teddy Bears, cats like to wrap their own tails around their bodies to get a sense of safety while asleep. If we notice a cat sleeping in such a position, we should not break its peace. Usually the tip of the cat's tail doesn't draw our attention. But its particular position may also show the cat's feelings. For example, a cat holding the tip of its tail pointed downwards may try to say that it is not feeling comfortable. So at this point, the cat not only feels angry, but also unsafe. This may again be a sign for us not to upset the cat in any way. In conclusion, cats use their tails in many different, sometimes funny ways to send us messages, and we can learn to know more. When a cat waves its tail strongly from side to side, it probably feels _ .

Sleep deprivation is an important hidden factor in lowering the achievement of school pupils, according to researchers carrying out international education tests. It is a particular problem in richer countries with sleep experts linking it to the use of mobile phones and computers in bedroom late at night. Sleep deprivation is such a serious problem that lessons have to be dragged down to a lower level to suit sleep-deprived learners, the study found. The international comparison, carried out by Boston College, found the United States to have the highest number of sleep-deprived students, with 73% of 9- and 10-year-olds and 80% of 13- and 14-year-olds identified by their teachers as being negatively affected. In literacy tests there were 76% of 9- and 10-year-olds lacking sleep. This was much higher than the international average of 47% of primary pupils needing more sleep and 57% among the secondary age group. Other countries with the most sleep-deprived youngsters were New Zealand, Saudi Arabia, Australia, England, Ireland and France. High-performing Finland is also among the most lacking in sleep. Countries with the best records for getting enough sleep include Azerbaijan, Kazakhstan, Portugal, the Czech Republic, Japan and Malta. The analysis was part of the huge date-gathering process for global education rankings, the Trends in International Mathematics and Science Study(TIMSS)and Progress in International Reading Literacy Study(PIRLS) "I think we underestimate the impact of sleep. Our data show that across countries internationally, on average, children who have more sleep achieve higher in maths, science and reading. That is exactly what our data show," says Chad Minnich of the TIMSS and PIRLS International Study Center. "It's the same link for children who are lacking basic nutrition," says Mr Minnich, based at the Lynch School of Education, Boston College. "If you are unable to concentrate, to attend mentally, you are unable to achieve at your best level, because your mind and body are in need of something more basic. Sleep is a fundamental need for all children. If teachers report such large proportions of children suffering from lack of sleep, it's having a significant impact. But worse than that, teachers are having to adjust their instruction based on those children who are suffering from a lack of sleep. The children who are suffering from a lack of sleep are driving down instruction." That means that even the children who are getting enough sleep are still suffering from this sleep-related lowering. Why are children who get enough sleep also victims?

Contestants from around the world met in Pomona, California, this month to test their skills at things like driving a car, walking down stairs, and opening doors. Sounds easy, right? But the competitors weren't people--they were robots! The bots were participating in the final round of the US's DARPA(Defense Advanced Research Projects Agency) Robotics Challenge. This event, which took place on June 5-6, tested robots on how well they could respond during a disaster and the winning team finally took home a $2 million grand prize. The DARPA challenge was created after the 2011 Fukushima nuclear disaster in Japan. An earthquake caused a tsunami, which damaged a nuclear power plant. Workers at the plant needed to shut off an important valve , but it was too dangerous for humans to reach it. The US scientists at DARPA wondered whether the disaster could have been avoided if a robot had been sent to do _ . So they set up the robotics competition. Turning a valve was just one task a robot might have to perform when entering a disaster zone. In addition to doing this, robots participating in the challenge had to navigate a course containing several other tasks: driving and exiting a vehicle, opening a door, walking over or clearing objects, cutting a hole in a wall, plus climbing a flight of stairs. Teams had to complete the challenge in one hour, and points were awarded based on how quickly the robots completed a task. They didn't have to attempt all the tasks. To make things even more realistic, challenge organizers caused short computer-system blackouts that prevented robots and the human operators controlling them from communicating. That means teams had to program their robots to be partially autonomous . Robots also couldn't be attached to anything that could keep them from falling down, which happened a lot. What do we know about this year's DARPA challenge?

In Canada you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends. Before they keep them in their houses, they take them to animal hospitals to give them injections so that they won't carry disease. They have special animal food stores, though they can get animal food in almost every kind of store. Some people spend around two hundred Canadian dollars a month on animal food. When you visit people's houses, they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a bird feeder( ) in their garden.

Are you carrying too much on your back to school? I'm sure lots of your age will say "Yes". Not only the students in China have this problem, but children in the United States also have heavy school bags. Doctors are starting to worry about that younger and younger students are having problems as a result of school bags being too heavy for them. "It's hard for me to go upstairs with my bag because it's so heavy," said Rich Hammond, an 11-year-old student in the US. Rich is among students who have common school bags with two straps to carry them, but many other choose rolling bags. But even with rolling bags, getting up stairs and houses is still a problem for children. Many of them have hurt backs and necks because of the heavy school bags. But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight. Scott Bautch, a black doctor, said children under Grade 4 should stay with 10%. But it is also important that older children don't stay with over 15%, because their bodies are still growing. "Children are losing their balance and falling down with their school bags," he said. Parents and teachers are starting to tell children to only take home library books that they will be reading at night. Some teachers are using pieces of paper or thin workbooks for students to take home. One of the best answers is, as some children said, to have no homework at all. From the passage we can learn that _ .

Nowadays the problem of the generation gap is becoming more and more serious. Poor relationship between parents and their children are very common. Whether we like it or not, our parents are responsible for us at least until we're out of high school. So rather than get upset about that fact, maybe we should focus on some ways to make our relationship better. The best way, in my opinion, is to learn to really communicate with my parents. When I find myself arguing with my mom and dad, I try to stop. If I can manage to stop myself from talking, I usually find that I can calm down quickly. I guess I'm usually acting out of emotion rather than logic . But if I can stop arguing for a minute, it seems that my opinion changes and I start to realize that I'm a bit childish. Emotionally I may still be upset, but logically I understand that yelling and fighting surely won't make things better. Once I've stopped arguing, I look at my parents in the eye. You'd be amazed at how much easier it is to communicate with your parents when you've actually looking at them. Looking away doesn't do much of anything except for giving them the impression that I'm not listening or that I don't care. It's much easier to see things eye to eye when you're physically seeing them eye to eye. Finally, I listen to what they're saying (or at least I try). Communication can't happen unless both sides hear and listen to each other. There is nothing wrong with my hearing, but that doesn't mean I always listen to the sounds that people are making. When I argue with my parents, I can physically hear what they're saying without mentally listening to it. Whether I admit it or not, my parents' experience can actually help them give me some pretty sound advice at times. I don't always agree with them, but I think it's safe to say that it has truly helped our relationship in the long run. What can we learn from the passage?

Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning . Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms. Certain microorganisms cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release poisons that make people sick. Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops. Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms. When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous. Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied. We know from the passage that the symptoms of food poisoning _ .

My friend got married. His mother carried two bags of cotton from the countryside by bus and train to his city. After arriving at the city, there was still a long way to his house without any bus passing by the house. His mother walked to his home breathlessly for 40 minutes without taking a taxi in order to save money. My friend felt bitter as well as funny at his mother's deeds. He pointed to the cashmere and silk quilts and said, "So long as you have money, you can buy anything in the supermarket. There is no need for you to carry so much cotton here in such a long way." But his mother insisted and said, "The cotton of this year is light and warmth-keeping. Have a try and you will know!" Maybe every parent is the same, caring for their children with stubborn love without caring about whether they know or like it. This early spring, I went to visit my grandmother. We had dry beans stew , eggplant salad bar, sauce radish for our dinner, all of which were dried by my grandmother last autumn and tasted wonderful. I loved the dishes to my heart's content and could not help praising them again and again. After a few days, my grandmother, who seldom visited us, came to my home and unpacked her bag, smilingly taking out bags of dried eggplants, dried beans and dried vegetable. She told me that I left so hastily last time that she forgot to give me some of these foods, so she took this chance to bring me what I liked. I was speechless at that time. Due to my casual complimentary her food, my grandmother, a nearly 70-year-old lady, by taking three buses from the west of the city to the east, came to my home with the food I liked. But she was bus-sick in life and even seldom went strolling in the street. My pretty girlfriend had a failed marriage in the past. After divorce, her parents shed the deepest protection and care to her by helping her attend to the child and offering financial aids. Her parents' love made her pull herself together and forgot the man who had hurt her before. Nonetheless, her father, an honest and upright old man, after hearing his ex-son-in-law got promoted in his company, felt terrifically irritated and went to his company to question his boss why a philandering man with corrupt conducts could get promoted. The whole office fell into a mess immediately and many staff just watched on the sidelines. Some people even whispered lightly, "It is a new era now and the relationship between men and women is very open. No one would care about that anymore!" The old man stood silently in the office with his hands shivering and eyes tearing. That night, my girlfriend cried heavily in front of me. I asked her whether it was her father's stupid deeds that made her feel _ But she said that she felt guilty for her dad and that though the rest of the whole world betrayed her, her old father would still back her up and help her get the justice she deserved, just as when she was young and the neighboring boy grabbed her ball, her father would get it back for her. However, this changed world was no longer the stage for her old father and his deeds became funnily obsolete. No one managed to see the real and ever-lasting love to his daughter behind his seemingly rude behaviors. Now we have grown up so much so that we could support our family and have our own children. But in our parents' heart, they are still worried that we do not have sufficient quilts and dried vegetables. They would not feel troubled to bring all these to us regardless of long tough journey. They even would not like us to suffer a bit and try all means to protect us without caring about whether what they do is awkward and stupid or not. Who in the world would love us so deeply and relentlessly without asking for any repay? Only our parents! From the passage we can learn the author's grandmother is _ .

Scientists have discovered a special biological behavior in dolphins that could lead to a treatment for late-onset diabetes in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning. The extraordinary finding has led scientists to suggest that dolphins have "genetic switch" that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect. If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity . The tissues of people with type 2 diabetes have become resistant to insulin so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys and nerves and contribute to 5% of all deaths, according to the World Healthy Organization. Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson's team analyzed 1,000 blood samples from 52 dolphins while they didn't eat anything overnight and fed in the morning. At night time, the dolphins' metabolism changed greatly and showed similar characteristics to that seen in people with type 2 diabetes. "It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans," said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego. The key to applying the finding to curing human diabetes lies in _ .

It is a matter of common observation that although incomes keep going up over the years,people never seem to become much better off! Prices are rising continuously.The condition is termed one kind 0f inflation, the money supply is becoming inflated so that each unit of it becomes less valuable.People have got used in recent years to higher and higher rates of inflation. What could be bought ten years ago for one dollar now costs well over two dollars. It seems that this rate of inflation is tending to rise rather than to fall.If in the real world our money incomes go up at the same rate as prices,one might think that inflation does not matter.But it does when money is losing value,it lacks one of the qualities of a good money---stability of value.It is no longer acceptable as a store of value;and it becomes an unsuitable standard of deferred payments.Nobody wants to hold a wasting possession,so people try to get rid of money as quickly as possible. Inflation therefore stimulates people spending,and prevents people from saving. According to the passage,if incomes and prices rise together _

It's a Friday night. Your girl friends are out at a bar and your boyfriend is playing soccer with his mates. Two text messages later, you're eating pizza and watching action movies with three guy friends. Perfect. "Guy friends" have the potential to enrich your life in ways that female friends and boyfriends just can't. For starters, they provide an insider's perspective on how men think, feel and behave. When dealing with male relatives, coworkers and even boyfriends, another man's point of view can be incredibly useful. Three hours spent analyzing a situation in a cafe with your girlfriends can't compete with a quick chat to a guy friend. Many women find that time spent with male friends can be a liberating and somewhat refreshing break from spending time with the girls. Without the judgmental gaze of other females, there is less pressure to dress up and compete for attention. Traditionally, girl-guy friendships are seen as hard to maintain. Most relationships between males and females that we come across in our day-to-day lives, whether in movies or books, are romantic by nature. These cultural images make girl-guy friendships seem impossible. Yet in reality, as gender roles loosen and equality becomes a norm in the workplace, it has become much more common for platonic friendships to blossom. "The belief that men and women can't be friends comes from another era in which women were at home and men were in the workplace, and the only way they could get together was for romance," explains psychologist Linda Sapadin to Psychology Today magazine. "Now they work together and share sports interests and socialize together." "My boyfriend has met all of my guy friends so he's quite accepting of me hanging out with them," says Nellie. "Because we've been dating so long, there's a level of trust where he knows I will make the right decision when choosing who to be friends with. "He understands that the kind of time that I spend differs between guys and girls. When I'm out with the girls, we're gossiping or talking about clothes but when I'm spending time with the guys, it's different. I think their carefree and 'whatever goes' attitude can sometimes be exactly what I need." In writer's opinion, girl-guy friendships _

Are You Right Handed or Left Handed? Which hand do you use when write? About 8 to 15 percent of people are left handed. They often have to use tools that are designed for right-handed people. So it is difficult for left-handers to use most tools. If you are right handed, try this experiment: Take a knife with your left hand and try cutting a potato into pieces. Don't be surprised if you feel awkward . In the past, people thought it was strange to use the left hand. Young students looked down upon their left-handed classmates. Some children were even punished for using their left hand to write. But these days parents and teachers have accepted that. In almost every school in the world, left-handed students can use their left hand to write. What causes people to be left handed or right handed? Experts have searched long and hard on this. They conclude that left-handed people are left handed for the same reason that right-handed people are right handed. One out of every ten people just is a left-handed people are right handed. One out of every ten people just is a left-hander. It's simply like the color of our eyes - some people have brown eyes, while some others have black eyes. However, may researchers think that left-handers and right-handers are different in some aspects. Right-handers are more talkative and outgoing than left-handers. Many right-handed people understand spoken words better. For example, after they listen to directions to a supermarket, they can find it easily. Right-handers are good at organizing people, too. They are also better basketball guards. Just ask Yao Ming. Research shows that left-handers are creative and artistic. Many famous performers, like Jim Carrey and Paul McCartney, are left handed. Many left-handers learn better visually . In art, both Leonardo da Vinci and Michelangelo were left handed. In music, Ludwig van Beethoven was left handed. In science, you find Newton and Einstein. The left-handed people are also really good at tennis and other single sports. If you prefer one hand, but you are still good at writing with the other, you are mixed. Research shows mixed-handers can remember everyday things better than other people. What did you eat for lunch two weeks ago? If you're mixed handed, you can probably remember.

Everyday we talk about and use the Internet, but how many of us know the history of the Internet? Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer network didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working on the time. At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made "surfing" in the Internet more convenient. Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.The Internet has now become one of the most important parts of people's life. Which of the following is TRUE?

Look at the light and beautiful snowflakes falling. Ever wanted to hold them in your hands? They are always lost when they meet your hands. Well, this isn't just a problem for you. It was a problem for Wilson Bentley, too. In the 1870s, Wilson Bentley was just a teenager. His family lived in a small town in northeast America. Winters there were long and hard. Bentley's mother was once a school teacher. She taught him at home. Bentley didn't go to school until he was 14. He was a quiet boy, and loved reading his mother's books. But he was interested in his mother's microscope . When the other boys were playing with balls, little Bentley was studying things like drops of water, flowers and snowflakes. Bentley loved watching snowflakes. For the next two years, young Bentley spent many winter days in a cold room watching these _ under his microscope. The boy thought they were beautiful enough for him to start to draw pictures of them. But there were so many snowflakes that he couldn't draw them all. How could he keep their beauty all the time? Bentley thought of buying a camera. The boy and his mother asked his father to buy one. But, his father didn't agree. He thought the whole thing was a bad idea. He thought the only thing a farmer should do was farming. But finally Bentley did get a camera. For more than a year he tried to take pictures of snowflakes. On January 15, 1885, during a snowstorm, Bentley took the first ever photo of an ice crystal with his camera. "It was the greatest moment of my life," Bentley said later. For 13 years, Bentley worked quietly and took thousands of photos of ice crystals. Later he became famous as "Snowflake" Bentley. Which of the following statements about Bentley is TRUE?

When Mary Moore began her high school in 1951, her mother told her, "Be sure and take a typing course so when this show business thing doesn't work out, you'll have something to rely on." Mary responded in typical teenage fashion. From that moment on, "the very last thing I ever thought about doing was taking a typing course," she recalls. The show business thing worked out, of course. In her career, Mary won many awards. Only recently, when she began to write Growing Up Again, did she regret ignoring her mom," I don't know how to use a computer," she admits. Unlike her 1995 autobiography, After All, her second book is less about life as an award-winning actress and more about living with diabetes . All the money from the book is intended for the Juvenile Diabetes Research Foundation (JDRF), an organization she serves as international chairman. "I felt there was a need for a book like this," she says." I didn't want to lecture, but I wanted other diabetics to know that things get better when we're self-controlled and do our part in managing the disease." But she hasn't always practiced what she teaches. In her book, she describes that awful day, almost 40 years ago, when she received two pieces of life-changing news. First, she had lost the baby she was carrying, and second, tests showed that she had diabetes. In a childlike act, she left the hospital and treated herself to a box of doughnuts . Years would pass before she realized she had to grow up ---again---and take control of her diabetes, not let it control her. Only then did she kick her three-pack-a-day cigarette habit, overcome her addiction to alcohol, and begin to follow a balanced diet. Although her disease has affected her eyesight and forced her to the sidelines of the dance floor, she refuses to fall into self-pity. "Everybody on earth can ask, 'why me?' about something or other," she insists. "It doesn't do any good. No one is immune to heartache, pain, and disappointments. Sometimes we can make things better by helping others. I've come to realize the importance of that as I've grown up this second time. I want to speak out and be as helpful as I can be." When Mary received the life-changing news, she _ .

After numerous warnings over the years, you thought coffee probably had a negative effect on your health. Perhaps the drink is not so bad after all. The new study, conducted by the National Cancer Institute (NCI), has been published and suggests that coffee does not have a harmful effect on your health. Researchers suggest, based on data examined, older adults who drink a lot of coffee, have a lower risk of death when compared to their non-drinking coffee peers. The team of researchers conducting the study analyzed data on 400,000 U. S. men and women,aged 50 to 71 years; the individuals had participated in the NIH-AARP Diet and Health Study. This study started in 1995-1996 and was tracked until the day a participant passed away, or Dec. 31, 2008. According to a press release on the report, researchers shared that coffee drinkers are "less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the relationship was not seen for cancer." Results indicated participants that drank three or more cups of coffee a day reduced their risk of death by 10 percent. Based on the findings that both caffeinated and non-caffeinated coffee found similar results, researchers are thinking caffeine is not the protective ingredient , although which ingredient in coffee might be, they are not sure. Researchers indicate that despite these observational findings, they caution it is not clear whether or not drinking coffee actually extends life expectancy. "Coffee is one of the most widely drunk drinks in America, but the relationship between coffee consumption and risk of death has been unclear. We found coffee consumption to be associated with lower risk of death overall, and of death from a number of different causes," said Neal Freedman, Ph. D., Division of Cancer Epidemiology and Genetics, NCI. "Although we cannot infer a relationship between coffee drinking and lower risk of death, we believe these results do provide some comfort that coffee drinking does not adversely affect health," Freedman said. Dr. Cheryl Williams, a registered dietician, told ABC News, "Overall, more research needs to be done to truly understand the ingredients in coffee and their biological activity and effect on health," said Williams. What can we infer from William's words?

What do you think of a " talking kitchen"? A French Digital Kitchen has been developed at Newcastle University in the UK. It teaches students how to cook French food and speak French at the same time. For the first time, students can learn a language by the following cooking steps. All grammar and _ have been carefully chosen to make sure the users can understand French well. After learning for some time, the users can test themselves by doing a short test on the computer. The kitchen project was started by Professor Paul Seedhouse. He became interested in the idea after he visited another kind of talking kitchen. He said, " The purpose of the French Digital Kitchen is to make learning a language more interesting and more educational." How does the kitchen work? There is a computer in the kitchen. With this computer, the users can first choose a French recipe( ) that they want to follow. Using information in the computer, the kitchen starts to guide the users how to make a French dish. If you follow the instructions on the computer, it moves on to the next. If you go wrong, the program goes back and repeats the recipe or information. At any time, the users can also ask the kitchen to repeat the recipe or any information.. The new kitchen can be used in school, universities and even people's homes. The researchers will also be developing the European Digital Kitchen, for the next three years. If the users don't follow the instructions on the computer, the kitchen _ .

On Thursday October 3, Adam Harper decided to stop drinking coffee. Adam is a MBA student at Harvard University. He studies long hours, gets very little sleep and as a result, he drinks a lot of coffee---anywhere from five to six cups a day. Recently, Adam felt that drinking thus much coffee was making it hard for him to sleep at all. He also began having problems with his concentration , and complained of stomachaches. Adam's doctor made this suggestions: stop drinking coffee altogether. When Adam got up on October 3, he began his day without his morning coffee. By 11:00 a.m., Adam was in a terrible mood . He was tired and had a headache. At 11:30, he had a meeting with his student advisor. In the meeting, he found it almost impossible to continue. What was going on? Caffeine, a chemical found in coffee, was most likely the reason for how Adam felt. Caffeine is a stimulant that boosts energy levels and improves concentration- but only for a short time. Lowering caffeine consumption often causes a drop in blood pressure and the result is a "coffee headache", People who stop drinking coffee often say they feel tired and moody, and find it hard to focus. The good news is that these feeling usually pass after four and five days. During this time, doctors suggested taking some aspirin for the headache. So, if Adam can wait, in less than a week, he may be feeling much better. What happened to Adam on Thursday October 3?

Sometimes children do not do what their parents tell them to do. When this happens, a parent tries to help the child to do the right thing. When this does not work, the parent usually punishes the child. There are many things that a parent can do. One thing that people have done is to spank the child. When a parent spanks a child, they will use their hand or a hard object to hit them on their bottom. This is meant to show the child that they have done something wrong. One parent remembers being spanked when he was a child. His parents used a stick. When he spanked his own children with his hand, he saw that he put a red mark on his child's leg. He never did that again. One problem with spanking is that it teaches the child to hit someone when they do not like what the other person is doing. Another problem with spanking is that the parent is usually angry and can hit the child too hard. Sometimes parents will use spanking for everything and not try other ways to get the child to do the right thing. Many parents are not sure of what to do instead of spanking. Some people think that their religion tells them that spanking is okay. Some think that the law lets them do it. The courts say that parents have the right to teach their children how to do things right. Other things should be tried before a parent decides to spank a child. Telling the child clearly what is wanted from them can be one thing. Giving a child more than one choice is another thing that can be tried. Getting down to the child's level and trying a more child- friendly way can help as well. Which of the following is NOT the problem caused by spanking?

[
"It teaches the child to hit others when they hurt his or her feelings.",
"The parent may get angry and hit the child too hard.",

Most middle school students find it boring to learn English. But students in Yat Sen middle school in New York, US, don't think so. Why? Because they are in the school of One Program, which asks students to work on their own or in small groups on computers to have math lessons. "The program gives the students a new learning style. No traditional classroom can compare with it. We give each lesson according to the students' interest and their strong and weak points," said JoelI. Klein, the school's head teacher, "we're looking for a new way that interest students children." Students enjoy these math lessons, especially lessons with video games. They must find out the answers to math problems to get through the game. One such game is Dimension M. As students move through mazes with their keyboards, some questions come up. Caleb Deng had to answer the question: What is 5+ (6x3)? He _ on paper quickly because there was just a minute left to play. " I was right," said Deng, 14, as he ended the game with a high score . "this really makes math lessons more exciting, since we are fighting to learn better." Which is NOT true of the program?

Many students attend Miami University for its zoology program, hoping to become a doctor someday, but Joseph Frame has come for a different reason -- to become a vet. "Ever since I was a little boy, I've been interested in animals," Frame said, "but when I grow up, I realized that I didn't want to just take care of dogs and cats. I wanted to work with animals you wouldn't find in your house." Before coming to Miami, Frame worked with his vet Dr. Reid. He learned about the details of being a vet from him. Working with small animals, Frame observed many procedures there. Frame also worked with another vet at Oxford University during his first year at Miami, which involved a leadership position. "I'm in charge of a high school kid," Fram said, "He sometimes needs to be motivated. I like his support system." To realize his goal, Frame began working at the Wilds in Cumberland, Ohio after he met Reid. The Wilds is a non-profit conservation center and is the home for rare and endangered animals. The Wilds combines the concepts of conservation science and education programs to mainly children. After his first year at Miami, Frame began to educate children about the animals. "I think teaching children is an enjoyable experience, especially when they're really interested in animals," Frame said. Frame also explained if a vet school didn't work out, he would be interested in working in animal education. "I would at least have a Zoology degree," Frame said, "The wilds is connected to many zoos all over the country, so I'm sure I can find a job in education." For now, Frame plans to continue working at the wilds this coming summer with a new job at hand, which involves teaching the public about the endangered animals they are protecting and doing shows with owls. While Frame is still an undergraduate student at Miami, he continues his passion for animals. Becoming an exotic vet may be a few years down the road, but Frame continues to work had for this dream, hoping it will become a great reality. What can be the best title for this text?

Babies who are slow to gain weight in the first months of their lives generally catch up to their peers by age 13,a large UK study shows, Researchers said the results would make parents whose babies fail to put on weight quickly less worried. The researchers looked at data from ,11,499 children who took part in a large study, It showed that 507 who were slow to gain weight in the first eight weeks of life recovered fairly quickly and had almost caught up by age 2. Another group of 480 who were slow to gain between eight weeks and nine months continued to put on weight slowly until they were seven years ,but then had a sudden increase and caught up by age 13, The different pattems of recovery between the two groups were likely due to different reasons for slow weight gain ,the researchers said, All the children were still lighter and shorter than their peers by the time they were teenagers ,but within the normal range. The findings highlight the importance of monitoring a baby's weight and height gain during the first few weeks and months ,but not creating anxiety with parents of slow-growing babies, said the study leader Prof Alan Emond from the University of Bristol. "In the past, a lot of parents have been caused unnecessary anxiety by heaith professionals and this is a positive and _ message."He said in many cases of slow growth where children do not follow the standard'curve' it is just because they are following their genetic potential. Dr Simon Newell, vice-president of the Royal College of Paediatrics and Child Health, said he broadly agreed with the concluslons of the researchers but stressed that poor weight gain was something that needed to be monitored closely, "I would encourage parents to use growth charts but if measurements show your baby is smaller than averager it may be completely normal, "he said. Which of the statements would Dr Simon Newell agree to?

"To some degree, growth charts can help parents monitor their babies' weight gain",

In South America, the rich soil of the Amazon River basin in Brazil is known as "black gold". Scientists found that the secret of this rich soil was charcoal . Local people made it from animal bones and tree branches. They mixed the charcoal with the soil about 1.500 years ago. Now, scientists in the United States have done a modern demonstration. They say charcoal fertilization offers a revolutionary way to improve soil quality for hundreds or even thousands of years. Mingxin Guo and his team at Delavare State University heated tree leaves, corn stalks , small pieces of wood and poultry waste into "biochar" . They reported their findings at a recent meeting of the American Chemical Society in New Orleans. Biochar could be good news for farmers with poor soil and hungry populations to feed. Professor Guo says it could even help against global warming. Intensive farming and overuse of chemical fertilizer give out carbon dioxide into the atmosphere. Biochar does the opposite, he says. It traps carbon in the ground. The researchers planted winter wheat in containers of soil in a greenhouse -- some with biochar, some without. Professor Guo says the wheat grows much better in the pots with biochar. The soil was added two percent charcoal to. But he says even a one percent treatment will increase productivity. The results demonstrated that biochar can increase organic matter in soil. Loss of nutrients in soil is an increasing problem worldwide as farmers try to grow more food for growing populations. Next, the team will carry out a five-year study of biochar with spinach , green peppers and tomatoes. Mingxin Guo says he learns about the "black gold" in Brazil from a magazine story. He explains that it was discovered in the jungle, in the area where waters flow to the Amazon, in the 1960's. But it was not until recent years that scientists began to bring public attention to it. Biochar has the following advantages EXCEPT that _ .

We are naturally drawn to friends and colleagues with familiar voices, scientists have found.People prefer those who have a similar accent,intonation and tone of voice to themselves , they discovered. Previous research has focused on how masculine or feminine a voice sounds.Men with deeper voices and women with slightly higher voices were thought to sound more attractive,because they suggest a bigger or a smaller body. But the new study,published by a linguistics expert in Canada,suggests there is a more complex mechanism at play.Dr Molly Babel, from the University of British Columbia in Canada, said,"The voice is an amazingly flexible tool that we use to construct our identity.Very few things in our voices are changeless,so we felt that our preferences had to be about more than a person's shape and size.'' She recorded 30 volunteers' voices and asked each to rate the others' attractiveness on a scale of one to nine.Each participant was from western America,with similar accents.The people we assessed were all in the same dialect group,but they showed that dialect to different degrees. "We seem to like people who sound like we sound,we like people who fit within what we know,"Dr Babel said.She also found that breathy voices in women-typified by the famous American actress Marilyn Monroe-were seen as more attractive. The breathy tone,caused by younger and thinner vocal cords ,implied youthfulness and health A creaky voice,suggesting a person has a cold,is tired or smokes,was seen as unattractive.The participants preferred men who spoke with a shorter average word length and deeper voices. The linguist,whose work is published in the journal PLOS One,said,"Once you're outside of a certain range of familiarity,novel and exotic sounding voices might become more attractive.We also have to keep in mind we find some accents more preferable than others because of social fixed ideas." The main purpose of the passage is to _ .

NEW YORK (Reuters Health)--Kids who eat better perform better in school, a new study of Nova Scotia fifthgraders confirms. Students who ate an adequate amount of fruit,vegetables,protein,fiber and other components of a healthy diet were significantly less likely to fail a _ test,Dr.Paul J.Veugelers of the University of Alberta in Edmonton and colleagues found. While a healthy diet is generally assumed to be important for good school performance, there has actually been little research on this topic, Veugelers and his colleagues note.To investigate,they looked at 4, 589 fifthgraders participating in the Children's Lifestyle and Schoolperformance Study, 875 (19.1 percent) of whom had failed an elementary literacy assessment. The better a student's eating habits based on several measures of diet quality,including adequacy and variety, the less likely he or she was to have failed the test, the researchers found,even after they adjusted the data for the effects of parental income and education, school and sex.Eating plenty of fruit and vegetables, and getting fewer calories from fat, was also associated with a lower risk of failing the test. To date, Veugelers and his team say, most research on diet and school performance has focused on the importance of eating breakfast, as well as the ill effects of hunger and malnutrition . "This study extends current knowledge in this area by demonstrating the independent importance of overall diet quality to academic performance.We should not only realize the importance of children's nutrition at breakfast but also that throughout the day," the researchers conclude. Another research from the UK is suggesting that children's diets in the preschool years affects how they perform at school later on.The researchers from the Institute of Education, at the University of London say in fact that what children were eating in those days before primary school has more of an effect than the chicken nuggets they ate at lunchtime.The researchers say they have found that children who ate a diet of "junk food" at the age of three, made less progress in school between the ages of six and ten.They say children's diet at later ages appears to have less impact on their school attainment. .It can be implied from the passage that _ .

85-year-old Tu is awarded the Nobel Prize for her contribution to reducing the death rate of malaria , minimizing patients' suffering and promoting mankind's health. This is what science is all about. Tu's name "Youyou", came from the Classic of Poetry. The characters depict the cheerful sounds deer make when calling for mates. Tu's finding has saved millions' lives during the 40 years. This also proves the value of her research product. The moment of joy and satisfaction when she discovered the artemisinin in 1971 after all kinds of failures in experiments is eternal. Tu has won some attention when she got the Lasker Award in 2011. But there is no way to compare her popularity back to the attention she is receiving today. She studied at the Peking University Health Science Center, Department of Pharmaceutical Sciences, from 1951 to 1955. Let's backtrack to 40 years ago. Tu finished the findings without using any advanced equipment, communication with outside world and papers to research. Nowadays, Chinese scientists have the passion to invent. As Premiere Li Keqiang mentioned in his letter, "Tu's winning the prize marks China's progress in scientific and technological field". Tu's winning will help people come to realize that all those international publications, whether it is the Nobel Prize, SCI publishing, Nature, or Science, are all just gimmicks of measuring tools. The sole key is to be oneself and try one's best with confidence. There had been doubts about "whether there would be a Chinese national awarded the Nobel Prize." This sort of doubts is unnecessary. The scientific awards are equal to all, as long as the research findings are good enough. The fact that Tu has none of these three backgrounds also reminds us that science should be more accessible to all. One shall be able to become a scientist no matter what kind of background he or she comes from, as long as one devotes into scientific research. They work so hard to prove the wrong way so that the future researcher will be closer to the right one. Artemisinin and science saved lived around the world. Tu saved the confidence of Chinese scientists, who will care less about whether a Chinese scientist be awarded the Nobel Prize in the future.

For children with cancer ,the facts of life include the facts of death. There is always the fear that they might not live to grow up.Yet they realize that fighting cancer is the only way of beating it. So they fight.And sometimes, they win.It may take years.It certainly takes support from parents and doctors. Unfortunately, many parents can't deal with their child's illness.And doctors, no matter how caring, have other patients to care for. At times like these, the Children's Cancer Foundation can help. We are a group of Hong Kong doctors, nurses, psychologists, parents of children with cancer and concerned persons .All of us are volunteers (offer one's help without payment).We're with the children every day, listening to, and encouraging them. We also advise parents, educate the public and send doctors overseas to study new cancer treatments. Our funding (providing money) has brought better equipment to the wards (large rooms of a hospital), and paid for special flats where the children can recover. We want to do even more.But to do it, we need your help. It will be money well spent.One who looks at our past achievements should prove that. To the children, your contribution will also be a show of support.A sign that you're behind them is just the sort of news that a six-year-old chlid with cancer needs to hear.

Who do you feel closer to -- your mom or your dad? In almost every culture in the world, mothers are thought to be more important than fathers during children's development and more likely to build strong bonds with their children. This belief had existed for a long time until scientists started asking a new question: What do fathers contribute to their children besides their genes? They must mean something, or they would have disappeared from children's lives at an earlier time in evolution . So, a new science of fatherhood was born. American journalist Paul Raeburn collected the discoveries over the years and put them into his new book, Do Fathers Matter? What Science Is Telling Us About the Parent We've Overlooked, hoping to make people better see the many ways that fathers influence their children. For example, Ronald Preston Rohner, a scientist at the University of Connecticut, US, spent several years studying how being accepted or rejected by parents influences children's personality. He found that children who are accepted by both their parents are usually independent and hold a positive worldview while those who feel turned down by either parent may turn out hostile and negative. Melanie Horn-Mallers, a psychologist at California State University, found that sons who have happy memories of their fathers are better able to handle day-to-day stress after growing up. Another study, by Richard Koestner at McGill University, Canada, focused on how children develop empathy . After looking at various possible factors, Koestner found one to be more important than others -- how much time their fathers spend with them. "We were amazed to find that how affectionate parents were with their children didn't matter much to the development of empathy," said Koestner. "And we were astounded at how strong the father's influence was." Indeed, evidence shows that fathers make unique contributions to their children's happiness. However, that doesn't mean that children in families without fathers are definitely going to become failures. Just look at US President Barack Obama. He is a great example of what can be achieved by people who grow up in single-mother households. It's been discovered by scientists that children feeling refused by their parents _ .

Cassandra Feeley finds it hard to manage on her husband' s income. So this year she did something more than a hobby: She planted vegetables in her yard. For her fist garden, Ms Feeley has put in 15 tomato plants, and five rows of a variety of vegetables. The family' s old farm house has become a chicke n house, its residents arriving next month. Last year, Ms. Rita Gartin kept a small garden. This year she has made it much larger because, she said,"The cost of everything is going up and I was looking to lose a few pounds too; so it' s a win-win situation all around." They are among the growing number of Americans who, driven by higher living costs and a falling economy , have taken up vegetable gardening for the first time. Others have increased the size of their existing gardens. Seed companies and garden shops say that not since the 1970s has there been such an increase in interest in growing food at home. Now many gardens across the country have been sold out for several months. In Austin, Tex, some of the gardens have a three-year waiting list. George C. Ball Jr, owner of a company, said sales of vegetable seeds and plants are up by 40%, over last year, double the averag e growth of last five years. Mr. Ball argues that some of the reasons have been building for the last few years. The big one is striking rise in the cost of food like bread and milk, together with the increases in the price of fruit and vegetables. Food prices have increase of higher oil price. People are driving less, taking fewer vacations, so there more time to garden. Which of the following might be the best title for the text?

Password strength has been a topic about the Internet lately. I have seen lots of clever methods for generating and remembering strong passwords. Some are better than others, but in my opinion , none are adequate . Here's the problem : it doesn't matter how strong your passwords are if you use the same one on multiple sites. All it takes is for a site to get hacked , like Gawker media, or even Sony did , and now your super-strong password has been stolen , and every site on which you used that password has been accessed . So, the bottom line is that no matter how strong your passwords are , and no matter what clever tricks you use to help you remember them , if you surf the Internet often , the only truly secure password system is what you need . Enter LastPass. It's not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access your LastPass database . The LastPass database is stored online, on LastPass's servers. LastPass recognizes the site you're on and automatically logs you in (after , optionally , asking you to re-enter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different , unique , very strong password for every site you log into , but you only have to remember one master password . It's the best of both worlds. One argument against LastPass is that if their database is attacked , then all of your sites are in danger, and that's true, but given that their entire line of work is keeping that information safe , I'm willing to take that chance. The alternative is rolling dice or picking phrase to create passwords, writing all of them down on a piece of paper or something , and then having to manually type them in when I go to a site . A terrible mess. There is a free version of LastPass , with additional features unlocked if you pay $ 12 for a year's subscription . ----Joshua Bardwell Joshua Bardwell writes the passage to _ .

A ban on smoking in public places has come into force in China - home to a third of the world's smokers. The move is aimed at controlling the number of deaths from smoking-related diseases, running at a million a year. But the rules have been criticized, because they do not include punishments for those who choose to ignore them. Many business owners hate rules that force them to ban smoking on their premises because many customers do not like the rules and complain. The rules do not allow smoking in places like restaurants, hotels, railway stations or theatres, but not at the office. Employers have a duty to warn staff off the dangers of smoking but do not have to forbid them from lighting up at their desks. Shanghai introduced similar rules a year ago, but people do not seem to take much notice of them. Often you find people smoking at the next table while you are eating your meal or having a drink in a bar. The problem is that the rules do not include punishments for businesses or individuals who ignore them. It appears that many Chinese people _ the dangers of smoking. Research suggests that only one in four knows the harm cigarettes of second-hand smoke can cause. Officials say they have to try to persuade people not to smoke to reduce the numbers dying from smoking-related diseases. At the same time the government makes a lot of money from the sales of cigarettes by the state-owned firm that makes and sells all tobacco products throughout the country. The number of smokers in China makes up about _ of the world's smokers.

Scientists have long had it in their mind to make a robot lizard . They began with finding out why a lizard can hang on a wall. They noticed the lizard's toes were unique: They have suckers , which enable it to hang on walls. They, therefore, made a robot with suckers on its hands and feet. The robot could hang on the wall but fell off when crawling. So, they went on researching. 6 years ago, scientists discovered that suckers only were not enough. It is the bristles on each foot that adds friction and static adsorption that makes a lizard move on the smooth wall easily without falling down. Then scientists made great efforts to fix thick bristles to the robot's hands and feet. However, the effect was not satisfactory. The robot still couldn't attach itself firmly to the wall. Scientists got puzzled: How on earth can the lizard crawl on an extremely smooth wall or even on a ceiling without dropping off? An accidental finding inspired them: One day a scientist happened to see an animal attack a lizard and bite off its tail. The lizard broke away from the animal's teeth and threw itself on a wall to escape, only to fall off heavily on the ground. The scientist wondered: Is it the tail that plays an important role in its travelling on the wall? He caught some lizards for an experiment. The result proved his assumption: A tailless lizard has no trouble walking on an ordinary wall but can't on a smooth one. A further study showed the lizard's tail can prevent it falling over backward and, what's more, that the tail acts as an additional leg while one of the lizard's legs leaves the wall, which is always the case while it is walking on the wall. Thus, Tailbot, a super tailed robot, is born. The biggest importance of a lizard's tail lies in _ .

Have you thanked your grandma today? You might want to consider it. A recent study found that kids live longer when a grandmother takes part in their daily lives. Most animals die soon after their childbearing years are over. Women, however, often live for many years after they stop having kids. To try to understand why, researchers from Finland looked at birth and death records of two communities from the 18th and 19th centuries, one in Finland and one in Canada. In these communities, 537 Finnish women and 3,290 Canadian women were grandmothers who had lived past the age of 50. For every decade they lived beyond 50, the researchers found that the women ended up with an average of two extra grandkids. It didn't matter what the differences in health or living conditions were between the two communities or from family to family. Grandchildren were also more likely to live into adulthood if their grandmothers were alive when they were born. If their grandmothers were younger than 60 at the time, that was even better. The study also found that women had children 2 to 3 years earlier if their own mothers were still alive at that time than those whose mothers had died. The researchers suggested that grandmothers have provided important assistance in raising their grandchildren for at least the past 200,000 years. As a result, they helped extend everyone's lifespan. So, don't take your grandma for granted! How did grandmothers help extend everyone's lifespan?

In nowadays,people tend to get married late.Does it have advantage or disadvantage?Different people have different opinions.Now let's have a look at a telated study about Americans. A study has found that marrying later in life is generally financially benfeicial for women,but not for men. The University of Virginia has published a report that college-educated women who get married in their thirties earn an average of 56 percent more than those who wed a decade earlier. In contrast,men who settle down in their twenties have higher intomes than those who wait until after 30,whatever their education. The Natioal Marriage Project's study,with the title:The Benefits and Costs of Delayed Marriage in America,examines the consequences of marrying later,a growing trend in the US. It notes that the average age of marriage is ag an all-time high of 27 for women and 29 for men,compared to 1990 when the averages were 23 for women and 26for men. But while wome have actually benefited financially from delayed marriages,men who getmarried earlier in life tend to be more successful later on. The study says that childbirth plays a role in these results. Around tow-thirds of lifetime income growth takes place during the first ten years of a career,according to clinical psychologist Meg Jay. Since college-educated women who marry in their twenties also tend to have their first baby earlier,forcing them to take a break from their careers. But getting hiched at a younger age tends to be a good career move for men,perhaps because married men are more sure of themselves and they have more responsibility for their family compared to single men ,leadng to more productivity,suggests Business Insider. The study also found that while college-deucated women profit from delayed marriage,those without a degree do not. In fact,among women who drop out of high school, 83 percent of first births are to unmarried mothers,according to the study. A woman without a college education therefore has less time to advance her career during ist vital first decade. The study also shows that men who never marry earn significantly less than those who do ,while the opposite is true for women. Why do college-educated women who marry earlier earn less?

If practicing an attitude of gratitude during the storms of life is too much for you right now, that's OK. When things are tough, most people have a hard time being thankful. They're so caught up in what's wrong in the present moment that they simply can't see some things are still right. If that's true for you, then accept it. You're going through a particularly difficult or unhappy period of time, and you don't like it one bit. Very normal, very human. But remember this: there is always something to be grateful for. It maybe only a small comfort right now, but it is a start. Make a list of some of the terrible things that didn't happen. For example: *You're in debt...but you're not homeless. *You lost your job...but you didn't lose your health. *You broke your leg...but you didn't break your neck. *Your mother has Alzheimer's disease...but your father doesn't. No matter how bad things are, they could always be worse. Start finding gratitude for what might have happened, but didn't. It does help a lot. Of course, you may not be thankful for everything-- but you can always be thankful for something. The writer thinks it _ for people to feel unhappy in time of difficulty.

Pigs are always considered dirty animals because they roll in mud.But in fact they prefer being quite clean.They cover themselves with mud to help stay cool.During cooler weather, they prefer to stay clean.So do elephants,who also cover themselves in dust or mud to keep cool. When they find a place with clean water they will take a bath,using their long noses to give themselves--or each other--a nice shower Some animals use dust to get clean.Chinchillas have very fine fur. They don`t like to take water baths because water is not warm enough for them.So, instead, they roll around in fine dust.The dust helps to keep their fur and skin dry.This protects them from disease Usually, a small bird is a light meal for a crocodile.But when a crocodile wants its teeth cleaned.it lies on the ground with its mouth open.The crocodile bird goes in and picks out any parasites between the crocodile`s teeth or under its tongue.The crocodile gets its mouth cleaned,and the crocodile bird gets dinner. You wouldn`t think fish would need baths.But some undersea parasites live under the fish`s skin."Cleaner"fish,like the wrasse ,help take them away.The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business.The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out parasites and bits of food.

Nowadays,the Internet,with its ability to connect people throughout the world,is changing the way people learn languages.There is still no way to avoid the hard work through vocabulary lists and grammar rules,but the books,tapes and even CDs are being replaced by email, video chat and social networks. Livemocha, a Seattle company, has created a website devoted to helping people learn more than 38 languages by exchanging messages over the Internet and then correcting each other's messages. The lessons,whether they are flashcards,quizzes,audio recordings or written and spoken essays,are delivered through the Intemet. Michael Schutzler, Livemocha's chief executive , says the website's advantage is the ability to practicel with a real person. "The great irony is that even if you have learned a foreign language in the classroom for years,you don't have confidefice to go into a restaurant and have a conversation with a foreigner,"he said.The casual connection with real people throughout the world, however brief, are not just fun and surprising but show more about how the language is really used. Livemocha is now experimenting with a variety of ways that resemble the games on other social websites to motivate people.The flashcard exercises,for instance,are scored, and the totals earned by studying and teaching appear on the users'front page. Besides,each person can set up a profile which includes a short description of his age,location and what language he would like to learn.Therefore,if you want to study one language,you will easily find many people who are fluent in it.Andl an email or two is all it takes to find a study partner. There are more and more companies like Livemocha offeritig online language learning to students throughout the world. And instead of merely helping people practice different languages,they also enable people to share interests and make new friends. How can one find a study partner on Livemocha?

Last week I talked with some of my students about what they wanted to do after they graduated, and what kind of job prospects they thought they had. Given that I teach students who are training to be doctors, I was surprised do find that most thought that they would not be able to get the jobs they wanted without "outside help". "What kind of help is that?" I asked, expecting them to tell me that they would need a or family friend to help them out. "Surgery ," one replied. I was pretty alarmed by that response. It seems that the graduates of today are increasingly willing to go under the knife to get ahead of others when it comes to getting a job . One girl told me that she was considering surgery to increase her height. "They break your legs, put in special extending screws, and slowly expand the gap between the two ends of the bone as it re-grows, you can get at least 5 cm taller!" At that point, I was shocked. I am short, I can't deny that, but I don't think I would put myself through months of agony just to be a few centimetres taller. I don't even bother to wear shoes with thick soles, as I'm not trying to hide the fact that I am just not tall! It seems to me that there is a trend towards wanting "perfection" , and that is an ideal that just does not exist in reality. No one is born perfect, yet magazines, TV shows and movies present images of thin, tall, beautiful people as being the norm. Advertisements for slimming aids, beauty treatments and cosmetic surgery clinics fill the pages of newspapers, further creating an idea that "perfection" is a requirement, and that it must be purchased, no matter what the cost. In my opinion, skills, rather than appearance, should determine how successful a person is in his/her chosen career. Many graduates today turn to cosmetic surgery to_.

If you have a bad habit of losing things, a new device that can be connected to any item that you might lose may be the way to solve your problem. The Tile, a small square linked up to your iPhone or iPad via Bluetooth, lets you see how close you are to the missing item, within a 50-to 150-foot range . If the item goes out of your phone's 150-foot range, it can still be detected on other smartphones with the same app. When you log into the app on your phone, it shows you, with green bars that increase or decrease, how far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost item -- a dog, for example, or a stolen bike -- goes out of your own phone's 150-foot Bluetooth range, you can set it as a "lost item". If any of the phones with the Tile app comes within the range of your lost item, a message will be sent to your own phone, reminding you of its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it. Since the Tiles use Bluetooth rather than GPS, they never run out of battery or need to be charged, and they last for one year before needing to be replaced. The app, which will come into the market this winter, works with iPhone 5S, iPhone 6, iPad Mini, iPad 3rd and 4th generation, and iPod 5th generation. Which of the following is TRUE according to the passage?

We are all busy talking about and using the Internet. But how many of us know the history of the Internet? Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time . At first the Internet was only used by the government , but in the early 1970s; universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and yet Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made "surfing" the Internet easier. Today it is easy to get online and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among young people. The Internet has become one of the most important parts of people s life. How long has the Internet been used?

Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests.That was the finding of a study of teenage males in Norway.Now,other research shows that physical activity may help students do better in their classes . The research comes as educators in some countries are reducing time for activities like physical education.They are using the time instead for academic subjects like maths and reading.The studies appeared between 2007 and 2013.They included more than 55,000 children,aged 6 to 18. Amika Singh:"Based on the results of our study,we can conclude that being physically active is beneficial for academic performance. There are,first,Physiological explanations,like more blood flow, and so more oxygen to the brain.Being physically active means there are more hormones produced like endorphins .And endorphins make your stress level lower and your mood improved, which means you also perform better." Also,students involved in organized sports learn rules and how to follow them.This could improve their classroom behavior and help them keep their mind on their work. The study leaves some questions unanswered,however.Ms.Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement.This is because of differences among the studies . Also.they were mostly observational studies.An observational study is where researchers do not do controlled comparisons.They only describe what they observe.So they might observe a link that students who are more active often have better grades.But that does not necessarily mean being active was the cause of those higher grades. The researchers said they found only two high - quality studies.They called for more high- quality studies to confirm their findings.They also pointed out that " _ Still,the general finding was that physically active kids are more likely to do better in school.Ms.Singh says schools should consider that finding before they cut physical education programs.Her paper on "Physical Activity and Performance at School"is published in the Archives of Pediatric and Adolescent Medicine. The passage mainly tells us that _
