What would it take to persuade you to exercise? A desire to lose weight or improve your figure? To keep you away from diseases? To live to a healthy old age? You'd think any of those reasons would be enough to get Americans exercising. Yet a vast majority of Americans have thus far failed to swallow the "exercise pill".

    Now a research by psychologists strongly suggests it's time to think of current well-being（幸福）and happiness as motivators for exercise instead of future health, weight loss and body image.

    Dr. Segar, one of the researchers, believes that immediate rewards are more motivating than distant ones. "People who say they exercise for the quality of life exercise more over the course of a year than those who say they value exercise for its health benefits." He said. '

    Other studies have shown that what keeps people moving depends on age, sex and life circumstances. For those of college age, physical attractiveness typically heads the list of reasons to begin exercising, although what keeps them going seems to be the stress relief that a regular exercise program provides. The elderly, on the other hand, may get started because of health concerns. But often what keeps them exercising are the friendships and sense of community that may otherwise be missing from their lives. Improving daily well-being is the most influential factor for the women. Men indicate they are motivated by more distant health benefits, but this may be because men feel less comfortable discussing their mental health needs.

    "Exercise should be encouraged but the emphasis on weight loss, disease prevention and healthy aging should be reduced." Dr. Segar concluded. "Exercise can make people feel more energetic, less stressed and, yes, happier."

    Many facts suggest that children are overweight (超重的) and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.

    Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.

    There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.

    There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.

    The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.

    Today's workplace is unique in history.Never before have we seen people working together who represent such different backgrounds and experiences.This difference of age,race,gender,and work style makes it very difficult to organize and run a company.

    As a result,companies are looking for individuals who can manage a wide range of employees effectively. Increasingly,managers are discovering that age differences among workers are a major cause of concern.

    This has been an important realization.The management difficulties and challenges have led some experts to study intergenerational differences for an understanding of problems in the workplace.What they have discovered is interesting and may provide ways of improving working conditions in companies that employ individuals from different generations.

    The first thing to realize,they say,is that differences of opinion about the importance of work and how to get work done are not a coincidence.That is,it is not an accident that young employees will be different from older employees.In fact,if employers do not pay attention to these differences,it is possible that anger will build up between people and lead to difficulties in the company.

    Resentment（仇恨）between members of different generations,if not attended to（处理）,can lead to extreme anger and unhappiness and even lasting enmity if people are not careful.That individuals from different generations should come to view each other as if they were from different sides of warring countries should not be surprising.

    It is natural for individuals from the same generation to form alliances（联盟）,to come together for protection. Different generations represent different experiences in life,and these lead naturally to different opinions about oneself and one's approaches to work.

    If you were raised in a time of plenty,when products were readily available and relatively inexpensive,you would believe that prosperity is natural and expectable.If,on the other hand,you were raised in a time of scarcity,you would always be careful not to waste things for fear you would not have enough.You would make angry people who seem to believe that problems will always solve themselves.Such optimism in the face of difficulties would be a source of unhappiness between you and them.It is difficult,in such circumstances,to achieve a happy,agreeable atmosphere in the workplace.

    I went online to check if my pay was in my bank account. To my amazement, I discovered that not only had I been paid, a company I'd never worked for had also paid me! I knew I'd have been beside myself if my own salary was not in my account, so I tried to get the money back to the right person. It is easier said than done.

    The bank couldn't help as it wasn't a bank problem. The human-resource department as the company that paid me was unable to help as I didn't have enough details. I rang the bank again. Thankfully I had sympathetic call operator who gave me a name, so I again rang the company "Daniel" worked for.

    I expected the bank would contact me to arrange to take the money from my account and repay Daniel. I heard nothing for a month and the money remained in my account when Daniel called, explaining he'd tried to get back his money but had been unsuccessful as neither the bank nor his company felt it was their error. He had rung to ask if I could speak to the bank, but after chatting for a few minutes we realized we could probably fix this problem ourselves.

    We decided I would take the money from my account and he would pick it up from me. Due to my busy job I was unable to meet Daniel personally but he left me a lovely bottle of wine in exchange for what was rightfully his. I never had any intention of keeping Daniel's pay, but red tape（繁琐手续）made it difficult to do the right thing. It all came down to two people being able to do what a huge bank and a large company couldn't do — admit a mistake has occurred and fix it.

    The latest IPCC report does not mince words(直言不讳地) about the state of our planet: we must act now to achieve global change at a scale that has “no documented historical precedent(先例)” in order to avoid the climate disaster that would result from a 2 degree C rise in average global temperature. Climate change already affects the world's most helpless people including poor rural communities that depend on the land for their livings and coastal communities. Indeed, we have already seen the clear asymmetry(不对称) of suffering resulting from extreme weather events, such as hurricanes, floods, droughts, wildfires and more.

    So far, advocates and politicians have tended to focus on reducing fossil fuel(矿物燃料) consumption through technology and/or policy, such as a sharp carbon tax, as climate solutions. These proposals are, of course, essential to reducing manmade carbon emissions(排放)-71 percent of which are produced by just 100 fossil fuel companies.

    Yet the international focus on fossil fuels has overshadowed(使......显得不重要) the most powerful and cost-efficient carbon-capture technology the world has yet seen: forests. Recent scientific research confirms that forests and other “natural climate solutions” are absolutely essential in reducing climate change. In fact, natural climate solutions can help us achieve 37 percent of our climate target, even though they currently receive only 2.5 percent of public climate financing.

    Forests' power to store carbon dioxide through the simple process of tree growth is staggering: one tree can even store an average of about 48 pounds of carbon dioxide in one year. Recent research show undamaged forests are capable of storing the same amount of the carbon dioxide emissions of entire countries such as Peru and Colombia.

    For this reason, policy makers and business leaders must create and strengthen ambitious policies to prevent deforestation, and support the sustainable management of standing forests in the fight against climate change. Protecting the world's forests ensures they can continue to provide essential functions aside from climate stability, including producing oxygen, filtering water and supporting biodiversity. Not only do all the world's people depend on forests to provide clean air, clean water，oxygen, and medicines, but 1.6 billion people rely on them directly for their livelihoods.

Dave McNee met Claudia Mandekic 14 years ago. When she told McNee how hard it could be to get students excited about math, her favourite discipline, he made a surprising suggestion: "Why not throw in something they enjoy, like sports?" The idea of mixing basketball and mathematics got its first shot in 2011, when the now colleagues — who had launched a tutoring non-profit — were invited to run a summer-school program for kids who'd failed Grade 9 math at Georges Secondary School.

When the students showed up for their first day, they weren't exactly excited. Over the next few hours, Mandekic and McNee gave the kids techniques to improve their shooting while also helping them calculate their field-goal percentage — which, in turn, taught them about fractions and decimal (分数和小数) points. At the end of the game, the winning team was determined based on which group had the highest total percentage and had done the most efficient math. "When the bell rang, they were so fixated on collecting their data and figuring out which team won that they didn't leave," says Mandekic. "I realized we might be onto something."

The classes, later named BallMatics, soon spread to other schools. "I was terrible at math," says Douglas, who enrolled in a fast-track summer program. "But once I started BallMatics and realized the sport I loved was directly tied to math, it made me a lot better at it. Every time I played basketball, I was thinking about math."

Almost any math problem, McNee and Mandekic realized, can be taught on the court. Kids can learn how to navigate an X-Y grid to find their next shooting spot or absorb the basic principles of trigonometry based on the angle at which they release the ball. In 2019, McNec and Mandekic established a private high school called Uchenna Academy. At the school, kids with top basketball skills can study all subjects, train at their sport and work part-time helping out with the BallMatics afterschool programs.

Douglas, now 20 and earning a degree in education believes the school's commitment to academics is the key reason it's been a winner. "If we didn't do our work, we weren't playing at the game," he says, adding that coaches would bench kids who didn't keep up in class. "At Uchenna, we were student athletes, not athlete students."
