??? We all have daily problems with technology, but how many of us can fix them? Mya Le Thai, a scientist from the University of California, Irvine recently discovered a process that might result in batteries that could last forever.
??? Thai said she was frustrated that the batteries for her wireless devices degraded. Over time, they failed to charge fully. Thai did not like to keep her wireless laptop connected to an electrical outlet. She decided to do something about that problem. At first, she and her team at UC Irvine thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithium-ion (锂离子)batteries to last forever. Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge. One of the reasons why lithium-ion batteries degrade is their use of nanowires (纳米线) to carry electricity. Nanowires are extremely thin. They are extremely efficient carriers of electricity, which makes them useful in batteries. But their thinness also makes them weak. ‘‘Nanowires break over time," she said. “That’s why they lose capacity.’’
??? But, Thai had a theory: The nanowires might last longer if covered with a gel. She and the team tested her theory. “ It was a long process and a lot of work," Thai said. The team tried many coverings for the wires. The nanowires were coated with a gel, PMMA, and cycled through charging 200,000 times. The gel showed no evidence of damage. The results suggested that batteries could last forever without losing charging ability.
??? Thai said 200,000 cycles amount to about three months on just one device. Thai hopes to continue her research to see if any other gel could work better.
??? Thai tells VOA she is enjoying the publicity about her discovery. She said she never expected her research to get media coverage. “It’s kind of cool,” she said. “I’m really glad people are showing interest in my work—not just in the work itself, but also in technology and energy.”

??? You might think that whether you choose a blue shirt or a yellow one to wear to work or college makes no difference to your day and those around you. However, an increasing number of experts argue that the colors we choose affect our mood, our career prospects and even our health.
??? The power of color has been used for centuries and we should be making the most of it in our lives. Color affects us to a greater degree than most of us realize. It is used increasingly by psychologists and therapists for influencing mood and state of mind, and for various types of treatments when we are ill. Some people even believe that the blind can benefit from the “vibrations(震动)” that color gives off.
??? Companies use color to great effect to encourage us

to buy their products. For example, purple is seen as creative and mixes well with red, to show that a company has ideas and the power to make them happen. Orange and blue are also recommended colors for companies to use, because orange is the color of communication and blue suggests safety and security. So this could be a particularly good combination. Companies have found certain colors “speak” to specific age groups. They often use red to attract younger people to their products, for example, as it is vibrant and more youthful than colors like gold and navy, which older customers seem to prefer.
??? Wearing different colors can affect how you feel and how others react to you, so it is important to consider this when deciding what to wear in the morning. If you want people to take you seriously, then wearing navy blue or black is good. Blue would also be helpful for an interview or oral examination because it relaxes you and makes you feel calm. Red gets you noticed by everyone and makes you, the wearer, feel energetic, but be careful, as it can raise your pulse rate and not everyone wants this effect.
??? So think carefully before you leave the house. The colors you choose are a wonderful tool. Are you making the right impression—on yourself and on others?

??? A new, first-of-its-kind study examines the connection between teacher burnout and students’ stress levels. Researchers from the University of British Columbia collected saliva(唾液) samples from over 400 elementary school children, grades four to seven, at 17 public schools. Cortisol(皮质醇) levels were then assessed from the samples as the hormone is commonly used as a biological indicator of stress. Correspondingly, teacher burnout was determined through survey results.
??? Investigators found that in classrooms where teachers experienced more burnout, or feelings of emotional exhaustion, students’ cortisol levels were elevated (提升). Higher cortisol levels in elementary school children have been linked to learning difficulties as well as mental health problems. The study appears in the journal Social Science & Medicine. "This suggests that stress contagion?might be taking place in the classroom among students and their teachers," said Eva Oberle, PhD, the study’s lead author.
??? Indeed, the relationship between student stress and teacher burnout is a chicken and egg question. "It is unknown what came first, elevated cortisol or teacher burnout. We consider the connection between student and teacher stress a cyclical problem in the classroom. ” Oberle said a stressful classroom climate could be a result of inadequate support for teachers, which may impact teachers’ ability to effectively manage their students. A poorly managed classroom can contribute to students' needs not being met and increasing stress. This could be reflected in elevated cortisol levels in students.
???

Alternatively, stress could originate from students, who may be more challenging to teach because of increases in anxiety, behavioral problems, or special needs. In this case, teachers could feel overwhelmed and report higher levels of burnout.
??? "Our study is a reminder of the systemic issues facing teachers and educators as classroom sizes increase and supports for teachers are cut,’’ said Oberle. “ It is clear from a number of recent research studies that teaching is one of the most stressful professions, and that teachers need adequate resources and support in their jobs in order to battle burnout and relieve stress in the classroom,” said the University of British Columbia education professor Kimberly Schonert Reichl, PhD, the study’s co-author. “If we do not support teachers, we risk the damage of students.”

??? While contact between adolescents (between the ages of fifteen and nineteen) and their peers(同龄人) is a universal characteristic of all cultures, the nature and the degree of such contact vary a great deal. In American contemporary society, adolescents spend much more time with their peers than with younger children or adults.
??? This pattern of age segregation(隔离) in American society did not become usual until the beginning of the industrialized society. Changes in the workplace separated children from adults, with adults working and children attending school. The dramatic increase of mothers in the workplace has further contributed to the reduction in the amount of time adolescents spend with adults.
??? School reform efforts during the nineteenth century, which resulted in age-segregated schools and grades, have reduced the amount of time adolescents spend with younger children.
??? Finally, the changes in population are considered a factor that may have contributed to the emergence of adolescent peer culture. From 1955 to 1975, the adolescent population increased dramatically, from 11 percent to 20.9 percent. This increase in the number of adolescents might be a contributing factor to the increase in adolescent peer culture in terms of growth in size as well as in terms of its impact on society's other cultures ( adults, younger children).
??? Research supports the view that adolescents spend a great deal of time with their peers. Reed Larson and his colleagues examined adolescents’ daily activities and found that they spend more time talking to their friends than engaging in any other activity. In a typical week, high school students will spend twice as much time with their peers as with adults. This gradual withdrawal from adults begins in early adolescence. In sixth grade, adults ( excluding parents) account for only 25 percent of adolescent social networks. Another important characteristic of adolescent peer culture is its increasingly autonomous(自治的) function. While childhood peer groups are conducted unde

r the close supervision of parents, adolescent peer groups typically make an effort to escape adult supervision and usually succeed in doing so.

??? There is some unwelcome news for students preparing for exams and officers putting in long hours—you don’t need the break as much as you may think that makes you feel less tired.
??? Scientists have long assumed that willpower is a limited resource, which is why you feel the need to have a rest, have a snack and come back to a task when you’re feeling better. They argued that the only way to restore willpower is by rest, food or entertainment.
??? But psychologists have challenged this theory, saying weak willpower is all in your head. They found that people’s beliefs in willpower determine how long and how well they’ll be able to work on a tough mental exercise. “ If you think of willpower as something that's limited, you're more likely to be tired when you perform a difficult task," said Prof. Veronika Job. “But if you think of willpower as something that is not easily used up, you can go on and on.”
??? The researchers designed four experiments to test students' beliefs in willpower. After a tiring task, those, who believed or were led to believe that willpower is a limited resource, performed worse on standard concentration tests than those who thought of willpower as something they had more control over. They also found that leading up to final exam week, students who believed the limited resource theory ate junk food 24 percent more often than those who believed they had more control in resisting temptation (诱惑).
??? According to Mr. Job, the theory that willpower is a limited resource is interesting, but it has had unintended consequences. Students who may already have trouble studying are being told that their power of concentration is limited, and they need to take frequent breaks. But a belief in willpower as a non-limited resource makes people stronger in their ability to work through challenges.
??? The findings could help people who are battling temptation. Willpower isn't driven by a biologically based process as much as we used to think. The belief in it is what influences your behavior.

??? Uploading countless selfies(自拍照), writing personal status updates,and checking your messages every other minute seem like just a part of modem daily life, right? These are the markers of the relationship we all have with social media now, which started out just as a way to communicate with one another.
??? According to a recent study by experts at the University of Georgia, there may be more to it than that. The findings suggested some unmistakable correlations between social media use and what’s known as “grandiose narcissism (浮夸的自恋)”.
??? So, when does social media use become a problem? Th

e University of Georgia carried out the research according to the following questions : How long do people spend on social media? How often do they tweet or update status? How many friends or followers do they have? How many selfies do they tend to post? If you do all the above things, it likely sends signals about your personality.
??? All of these online actions have one thing in common : They are all ways in which we try to promote ourselves online. Therefore, it9s how you use the platform that counts.
??? Then, exactly how much time spent online is too much? The researchers didn't measure. However, another study from Baylor University listed SALIENCE (social platforms becoming necessary in your daily life) and EUPHORIA (the feeling of excitement when you use them) among other things as signs of addiction. That is to say, if you are constantly engaged with social media on a daily basis, it could be a sign that you have a negative relationship with it.
??? Therefore, it’s how you use the platform that matters. Social media itself means no harm. Instead, more benefitscan be got if you use it carefully and wisely.

??? American English began in the 17th century. At the beginning of the 17th century, the English language was brought to North America by colonists from England. They used the language spoken in England, that is, Elizabethan English, the language used by Shakespeare.
??? In order to exploit new resources in America, British colonists settled down there and from 1607 to 1732 set up thirteen colonies, including Virginia, North Carolina,Georgia, Pennsylvania, New York, New Jersey and Connecticut. In these thirteen areas, English was a common language used by all people. The first colonists established the English form in America.
??? As time went by, the English language gradually changed on both sides of the Atlantic. Foreigners longing for wealth set foot on the coastal area to trade. Americans adopted many words from foreign languages and invented numerous new words to meet their commercial needs.
??? Following American Independence, famous people like Thomas Jefferson, the President, began to consider that the country should have a language of its own. Noah Webster compiled (编撰) three elementary books on English. Later, he expressed the idea that as an independent nation, America should have a system of its own in language as well as in government. After the second half of the 19th century, many great writers such as Mark Twain helped the development of American English.
??? English in America has developed a character of its own, reflecting the life and the physical and social environment of the American people. Since the rise of the United States to a position of world importance, American English has been developing and changing. There is no doubt that American English will enrich the English language greatly. With the rapid development of

modem mass media and the common needs of economic, cultural and politicalexchanges, American English will be more widely used in the world than British English.

??? Life doesn’t always turn out the way we’d like. When situations take an unfriendly turn, we become upset, frustrated, and angry. When others don't agree with us, live their lives the way we think they should not, or act in a manner we find disturbing, anger is a typical reaction. It seems that we feel anger gives us the momentary feeling of power in a situation where we feel we have lost authority. However,in fact,with the exception of a few cases,an angry reaction rarely improves the situation. It only makes the situation worse. Thoughtful consideration of what feelings and replies are most advantageous actually restores real power. So consider the following alternatives to anger.
??? One is compassion, which consists of both understanding and empathy.?If we view an individual whose behavior we find unacceptable, we should think each person has a right to live life according to their beliefs, dreams, needs and so on. Even if someone is acting improperly, you should understand them rather than get bent out of shape. If they are struggling, lost, or in pain, you should choose to feel empathy for their suffering, hoping that they will soon pass through their current challenge to a more joyful place. If you do so, your anger will disappear.
??? Humor is another powerful tool for stopping anger because it can help you stay calm when things get bad. Sometimes we take life far too seriously. That is bad for us and anger is easy to happen. We need to use humor to turn any serious situation into a light one. Humor acts as a protective barrier to emotional pain.
??? Therefore, when others behave badly, find it in your heart to forgive them for their unwise behavior rather than complain. When life hands you the exact opposite of what you requested, take no notice of it instead of getting angry. After all, the bad situation is only temporary. So choose these alternative reactions to soften our heart and prevent anger from happening so that we can enjoy our life to the fullest.
