Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises, according to scientists. They say that socialising and meeting with friends help increase levels of brown fat in the body which burns calories(卡路里)to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks, even if they ate more. US researchers say that social excitement aids weight loss by turning white fat into brown. White fat stores calories and makes us fatter, while brown burns energy to produce heat. Turning white fat into brown is extremely difficult,normally requiring long- term stay in cold conditions or exciting part of the body's nervous system.
However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those, who lived alongside a greater number of mice, had more space and toys to excite themselves and then lost far more weight over the course of the study than their “couch potato" fellows.
Study author, Dr Matthew During, whose team's findings appear in the journal Cell Metabolism, said, "I'm still amazed at the degree of fat loss that occurs." Explaining how new technology had threatened face-to-face socialising, he added, "It's not just a sedentary(久坐 的)lifestyle and high calorie foods, but an increasing lack of social activities." Co-author Dr Lei Cao said,"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital.,,

I’ll never lose weight--I come from a fat family
Wrong! While we can't change the body type we are born with, we can't blame our genes for making us fat. There's plenty of evidence that fatness runs in families, and the main reason is that they share the same habit of eating too much and exercise too little.
I am fat because I burn calories slowly
Wrong! Fatness is not caused by a slow metabolism(新陈代谢).In fact, although fat people consume more energy than slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake mom accurately.
Exercise is boring
Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied program that's fun as well as progressive. If you enjoy a Sunday walk, take a different mute. If you do yoga, try a Tai chi class. If you like swiping, set yourself a distance or time challenge.
No pain, no gain
Wrong! Exercise is not meant to hurt. Indeed, pain is you body telling you something's wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this is your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If they don't, rest and seek medical advice.

But why do people get these dark eye bags?The answer is both genetic (that is, relating to your DNA) and environmental (a result of your everyday living, such as rubbing your eyes or getting too little sleep),said Dr. Carol Clinton,a skin-care researcher in Dublin,Ohio.
But "the biggest reason is genes." Clinton told Live Science.Eye bags are generally more noticeable in people who,because of genes,have thin or pale skin.When people are tired or very nervous,blood circulation in the eye area becomes slow,allowing blood to pool there.Clinton said.Capillaries (毛细血管) stand out,leading to dark eye circles, she said.Besides,eye bags result from eyes' fat moving forward. An age-connected increase in fat beneath the eyeballs leads to eye bags."Anyway,when your eyes' fat is moving forward,you may think about having an operation in that area," Clinton said,"A person can get 9 hours of sleep a night,but still have eye bags because of a genetic development."
In other cases,environmental problems cause eye bags.For example, allergies (过敏)-especially seasonal allergies-can cause capillaries to stand out.Getting too much sun can also damage and thin the skin,making dark circles under the eyes easy to see.Besides,eating salty foods can cause the body to hold more water, which makes eye bags worse,according to the Mayo Clinic.

【推荐3】One in four children and young people could have problematic smart-phone use, according to research that also suggests such behaviour is associated with poorer mental health.
The amount of time children and teens spend using their devices has become an issue of growing concern, but experts say there is still little evidence as to whether spending time on screens is harmful in itself.
The experts behind the latest study said they wanted to look beyond the time young people were spending on smart-phones and instead explore the type of relationship they had with smart-phones.
The results suggest more than 23% of young people have an abnormal relationship with their smart-phones, and that this appears to be associated with poorer mental health-although the research cannot say whether phone use is driving such problems.
“It seems like only a minority of teenagers and young people from various different countries are self-reporting a pattern of behaviour that we recognise from other addictions,” said Dr Nicola Kalk of King’s College London, co-author of the study. “The quality of the evidence is poor, but it is enough to warrant (保证) further investigation.”
Writing in the journal BMC Psychiatry, the team reported how they looked at data from 41 studies involving a total of almost 42,000 participants across Europe, Asia and America, mainly in their teens or early 20s.
These studies used questionnaires to probe the prevalence (普遍) of problematic smart-phone use-behaviours such as being anxious when the device is not available or neglecting other activities to spend time on the smart-phone.
Taken together, the team said on average these studies suggested as many as one in four children and young people had problematic smart-phone use.
Among the studies that probed mental health, the results suggested people with problematic smart-phone use were also more likely to have depression-for which the odds (可能性) were more than three times worse-anxiety, feelings of stress and poor sleep as well as poorer educational attainment.
While the team said it was too soon to call problematic smart-phone usage an addiction, they noted that it appeared to be linked to similar patterns of behaviour and emotion.
Kalk said further studies were needed to explore if these behaviours were hard to break, or cause harm-other key features of an addiction.
The authors argued that the availability and pervasiveness of smart-phones in everyday life meant problematic use of the devices posed a different and much bigger public health problem than substances of abuse or internet gaming.
Kalk said the team were now looking at whether smart-phones were just delivering addictive content, or whether there was something inherently addictive about using such devices.
Dr Amy Orben, an expert in screen time at the University of Cambridge, raised concerns, noting that the definition of problematic internet use varied considerably across studies, and the measures used were questioned.
She said studies finding little signs of problematic internet use might have been overlooked, while the research could not say whether problematic smart-phone use caused poorer mental health.
Prof Russell Viner, President of Royal College of Paediatrics and Child Health, said that parents were navigating unchartered water when it came to technology.
“One of the most critical things for parents to consider is whether screen time is having a harmful impact on other activities like school, relationships or other interests. This study suggests that this is the case for a significant minority of children and young people,” he said.
Viner said in these cases parents should calmly install age-appropriate boundaries on smart-phone use, and ask questions about whether their children were experiencing other problems.
“While screen time is a new problem, part of the solution is tried and tested-open and regular conversations based on respect and trust,” he said.

【推荐1】Suppose nearly every student passed the tests. What would the respond be from politicians, business people and the media? Would these people shake their heads in admiration and say, "Damn, those teachers must be good!"?. But in the real world, it would be mentioned as evidence that the tests were too easy. For example, when results on New York's math exam rose in 2009, the minister of the state's Board of Regents said, "What today's scores tell me is not that we should be celebrating, but that New York State needs to raise its standards."
The unavoidable and deeply disturbing effect is that "high standards"really mean "standards that all students will never be able to meet". If everyone did meet them, the standards would just be ratcheted up again---as high as necessary to ensure that some students failed.
The standards-and-responsibility movement is not about leaving no child behind. On the contrary, it is a detailed sorting device, intended to separate wheat from chaff(谷壳). The fact that students from low-income- families and students whose first language isn't English are disproportionately(不成比例地) defined as chaff makes the whole enterprise even have more gradual and accumulated effects.
But my little thought experiment uncovers a truth that extends well beyond what has been done to our schools in the name of "raising the bar", We have been taught to respond with suspicion whenever all members of any group are successful. In America, excellence is regarded as a rare product. Success doesn't count unless it is obtained by only a few. The goal, in other words, isn't to do well but to defeat other people who are also trying to do well. Grades in this view should be used to announce who's beating whom. Comparative success just gives the winner rights to talk"We're No.1!" proudly. And again, it creates the misleading impression of unavoidable, permanent failure for some.

【推荐2】Risky play gives children a feeling of thrill and excitement. Risk is an essential part of a balanced childhood. Exposure to healthy risks, particularly physical, enables children to experience fear, and learn the strengths and limitations of their own body.
For this generation of children, always from scheduled soft play, to school, to club, to sofa, we’ve got a lot of work to do. As parents, many of us are unused to allowing even the tiniest degree of danger to enter the lives of our children. Surely it’s the job of a good parent to keep them safe.
That’s why roaming-distance — how far children play from home — has decreased by 90% in the past 30 years. We are a nation of stubborn helicopter parents, managing a schedule of activities and waiting below our children on the monkey bars in case they should slip. It’s no wonder that the virtual risk of computer games is so appealing and addictive—the real world seems rather mild in comparison.
So how can we put some of that danger and excitement back into the lives of our children? The answer is step by step and in an age-appropriate way. First, the outdoors is key. Outdoors time every day is essential, and don’t just head to the neat and controlled environment of the play area. Permit your primary-age children to leave your sight. Risky sports are a reasonably controlled way to allow your children to feel fear. Horse riding or skiing might be expensive, but what about skateboarding, tree-climbing or rock-climbing? Your child could fall at some stage, and they will probably feel out of control — but wow, they’ll feel alive. Water, too, is an essential healthy risk. Let them climb in streams, slide in mud and fall over in the sea wearing all their clothes. Your job as an adult is to manage the risk.
1. What is the author’s concern about the children according to the passage?A.They are exposed to too many risks. |
B.They are addicted to computer games. |
C.They are unwilling to experience the fear. |
D.They have less access to enough risky play. |
A.The balanced schedule of activities. |
B.Doing too much homework. |

D.Encourage kids to play in a cleaner environment. |
A.Letting your kids experiencing healthy risks will benefit their growth. |
B.How to manage the risks for your kids is the parent’s job as an adult. |
C.Parents should keep your kids free from risks step by step. |
D.It’s the parents’ responsibility to play with your kids in risky sports. |
【推荐3】Top College Graduates Get Paid More, but do They Perform Better?
It’s generally believed that better universities attract better students and provide better training, so it makes sense to use the university rank as a predictor of employee performance. But is it a good hiring strategy? Do university rankings predict job performance? Our research suggests yes — but only to a degree.
In a recent study, we tested the relationship between the university rank and performance of graduates. We tracked the performance of 28,339 students from 294 universities that ranked from Top 10 to about top 20,000 in the Webometrics global university rankings.
Our results offer some comfort to the traditional recruiters. After controlling for age, gender, and the year of study, we found that graduates from higher-ranked universities performed better, but only nominally and only on some dimensions of performance.
Second, higher-ranked universities should provide better training. Top universities employ better instructors, offer access to better-equipped facilities, attract better speakers and guests to campus, which in turn, should lead to better training and subsequent performance.
Finally, it might be expected that higher-ranked institutions might provide a more stimulating academic environment.
Despite their slightly better overall performance, hiring graduates from higher-ranked institutions could have a downside. Our data suggest that students from higher-ranked universities might damage team cooperation, sometimes carelessly.
A.Indeed, education is not only lectures and seminars. |
B.However, our study revealed no difference in the following aspects. |
C.They clearly know that interpersonal relationships at work play a critical role in career success. |
D.They tend to excessively focus on the instrumental tasks, paying insufficient attention to interpersonal relationships. |
E.We also found several reasons why the graduates from the top universities performed better than those from the lower-ranked schools. |
F.We observed the students’ performance for two months as they were working in global virtual teams on real-life business consulting projects. |
【推荐1】Psychology has a new application in the field of medicine. Many doctors, together with their patients, are looking for alternative methods of treatment of physical problems. In large hospitals, modern therapy seems to focus on the physical disease. Patients may feel they are treated like broken machines. Some doctors have recognized this as a problem. They are now using psychological therapy, in which the patient is working with the doctors against the disease with the help of medicine. The patient does not wait for the medicine and treatment to cure him or her, but instead the patient joins in the fight.
The doctor knows that a disease affects a patient’s body physically. The body of the patient changes because of the disease. He is not only physically affected, but also has an emotional response to the disease.
Because his mind is affected, his attitude and behavior change. The medical treatment might cure the patient’s physical problems, but the patient’s mind must fight the emotional ones. For example, the studies of one doctor, Carl Simonton, M. D., have shown that a typical cancer patient has predictable attitudes. She typically feels depressed, upset, and angry. Her constant depression makes her acts unfriendly toward her family, friends, doctors, and nurses. Such attitudes and behaviors prevent recovery. Therefore, a doctor’s treatment must help the patient change that. Simonton’s method emphasizes treatment of the “whole” patient.
The attitude of a cancer patient receiving radiation therapy, an X-ray treatment, can become more positive. The physician who is following Simonton’s psychological treatment plan suggests that the patient imagine that he or she can see the tumor in the body. In the mental picture, the patient “sees” a powerful beam of radiation like a million bullets of energy. The patient imagines the beam hitting the tumor cells and causing them to shrink. For another cancer patient, Dr. Simonton asks him to imagine the medicine going from the stomach into the bloodstream and to the cancer cells. The patient imagines that the medicine is like an army fighting the diseased cells and sees the cancer cells gradually dying and his blood carry away the dead cells. Both the medical therapy and the patient’s positive attitude fight the disease.
Doctors are not certain why this mental therapy works. However, this use of psychology does help some patients because their attitudes about themselves change. They become more confident because they use the power within their own minds to help stop the disease.
Another application of using the mind to help cure disease is the use of suggestion therapy. At first, the doctor helps the patient to concentrate deeply. The patient thinks only about one thing. He becomes so unaware of other things around him that he is asleep, or rather in a trance (催眠状态). Then the physician makes “a suggestion” to the patient about the medical problem. The patient’s mind responds to the suggestion even after the patient is no longer in the trance. In this way, the patient uses his mind to help his body respond to treatment.
Doctors have learned that this use of psychology is helpful for both adults and children. For example, physicians have used suggestion to help adults deal with the strong pain of some disease. Furthermore, sometimes the adult patient worries about her illness so much that the anxiety keeps her from getting well. The right suggestions may help the patient to stop being anxious. Such treatment may help the patient with a chronic(慢性的) diseases. Asthma (哮喘) is an example of a chronic disorder. Asthma is a disease that causes the patient to have difficulty in breathing. The patient starts to cough and sometimes has to fight to get the air that he or she needs. Psychology can help relieve the symptoms of this disorder. After suggestion therapy, the asthma patient breathes more easily.
Physicians have learned that the psychological method is very useful in treating children. Children respond quickly to the treatment because they are fascinated by it. For example, Dr. Basil R. Collison has worked with 121 asthmatic children in Sydney, Australia, and had good results. Twenty-five of the children had excellent results. They were able to breathe more easily, and they did not need medication. Another forty-three were also helped. The symptoms of the asthma occurred less frequently, and when they did, they were not as strong. Most of the children also felt better about themselves. Doctors have also used suggestion to change habits like nail-biting, thumb-sucking, and sleep-related problems.
Many professional medical groups have accepted the medical use of psychology and that psychology has important applications in medicine.

【推荐2】Are you a loser? Great. Because studies show that if you want to be a success, you need to know how to fail.
The Secret of Success
Many social scientists agree that what successful people have in common is this: They were failures.
There’s George Washington, the top general of America’s troops in the Revolutionary War, who lost two huge battles and was nearly fired. There’s Steve Jobs, who developed failed products, before returning to change the world with the iPod, iPhone, and iPad. The list goes on: From Katy Perry and Hall of Fame basketball legend Michael Jorden to Glee star Chris Colfer. They were dropped from record labels, cut from basketball teams, or bullied in school. They used to feel humiliated, lost and hopeless.
But they eventually figured out how to move forward. Experts call this resilience---being able to recover from setbacks. Amy Fineburg, Ph.D.,a specialist in psychology said “We grow by pushing beyond the limits of what we can do today.” So next time you fail a test or strike out at bat or sing off-key, don’t give up.
“That’s how we grow,” says Amy Fineburg, Ph. D., an Alabana educator who specializes in Psychology. “We grow by pushing beyond the limits of what we can do today.”
Miranda’s Story
Miranda stared tae kwon do when she was 7, and for years she lost every competition she entered. She decided to quit. However, at the urging of her father, she worked harder, got improved, kept at it and improved even more. Miranda never became the champion she’s dreamed of becoming, but she stuck with it long enough to earn her black belt by age 12.
“I could easily have said: I’m a failure, I should never have tried,” she says. “But I’m really proud that I kept at it.”
The experience taught Miranda that she could fail and still go on to succeed. Today at 17, she finally winning medal---at Irish stepdancing. When she first started, she was bad at that, too. But her experience in tad kwon do built up her resilience muscles. So she didn’t see her struggle in dance as failures. She saw them as part of the process of achieving success.
The Right Attitude
One of history’s proudest failures was inventor Thomas Edison. He looked at his failures as situations that he could fix. So how resilient are you? Say you do poorly on a text in school, do you say, “I did badly because I watched TV last night?” Then how to move in is obvious: Turn off the TV and study harder. Or would you say, “I failed the test because I have zero talent in math?” With this type of thinking, changes seem impossible to make.
The good news? Studies show that with Practice, people can change their way of thinking.
Just ask Michael Jordan
“I’ve missed more than9,000 shots in my career,” he says. “I’ve lost almost 300 games. 26 times I’ve been trusted to take the game-winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed.”

You have heard the expression “horse sense”. As you may imagine, it came from the time when the majority of people traveled in vehicles drawn by horses. A horse does have a lot of common sense, and there are many true stories about horses having saved their drivers from danger of death.
Today for the most part, people travel by train, ship, airplane, and car, but very little by the use of horses. Modern vehicles are propelled by engines, and an engine does not have any sense. In case of danger, many horses could be depended on to help. Not so with the engine; the driver must do all the things.
In recent years, the speed of travel has increased greatly. With the increased speed comes greatly increased danger. The driver of a powerful engine needs to be careful. A moment of being careless may cost a life. In order to drive today, a person must be able to see clearly, and he must learn and follow carefully the rules for safety on the road. Greater attention is the price we pay for using a machine instead of a horse.
1. The passage mainly talks about ______.
A.engines | B.safe driving | C.using horses | D.modern machines |
A.repair | B.raise | C.push forward | D.made |
A.a driver must know the rules of safety |
