When asked about happiness, we usually think of something extraordinary, an absolute delight, which seems to get rarer as we get older.

    For kids, happiness has a magical quality: Their delight at winning a race or getting a new bike is unreserved (毫不掩饰的).

    In the teenage years, the concept of happiness changes. Suddenly it's conditional on such things as excitement, love and popularity. I can still recall the excitement of being invited to dance with the most attractive boy at the school party.

    In adulthood the things that bring deep joy－love, marriage, birth－also bring responsibility and the risk of loss. For adults, happiness is complicated (复杂的).

    My definition of happiness is “the capacity for enjoyment”. The more we can enjoy what we have, the happier we are. It's easy to overlook(忽视) the pleasure we get from the company of friends, the freedom to live where we please, and even good health.

    I experienced my little moments of pleasure yesterday. First I was overjoyed when I shut the last lunchbox and had the house to myself. Then I spent an uninterrupted morning writing, which I love. When the kids and my husband came home, I enjoyed their noise after the quiet of the day.

    Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work. I don't think that my grandmother, who raised 14 children，had much of either. She did have a network of close friends and family, and maybe this is what satisfied her most.

    We, however, with so many choices and such pressure to succeed in every area, have turned happiness into one more thing we've got to have. We're so self-conscious about our “right” to it that it's making us miserable. So we chase it and equal it with wealth and success, without noticing that the people who have those things aren't necessarily happier.

    Happiness isn't about what happens to us－it's about how we see what happens to us. It's the skillful way of finding a positive for every negative. It's not wishing for what we don't have, but enjoying what we do possess.

    Kawhi Leonard,who won the 2014 NBA Championship with the Spurs and was named the Finals Most Valuable Player,finished the 2016-17 season with averages of 25.5 points,5.8 rebounds,3.5 assists and 1.8 steals per game in the regular season,and 27.7 points,7.8 rebounds,4.6 assists and 1.7 steals in the playoffs.Then he was selected to the All-NBA First Team for the second time in his career,as well as earning All-Defensive First Team honors for the third time in three years.He's hopeful the playoffs happen to him again next season.

    He lived up to his reputation as the quiet man of the NBA in Beijing on Friday,but that didn't mean he wasn't enjoying himself.The San Antonio Spurs star rarely gets too animated—at least off the court.However,as he explained,people shouldn't read too much into it—it's simply his humble manner.

    Two-time All-Star Leonard is on week-long trip to China - his first visit here - until Aug 24 to promote basketball.Leonard hosted a basketball clinic in Beijing on Sunday for talented migrant school-kids,and on Saturday also met fans at NBA 5v5,the league's five-on-five tournament for elite players in China.

    The 26-year-old will then pay a visit to the NBA Academy Zhejiang in Zhuji,an elite training center which opened last November,to put the young talent there through their paces.“Just make sure that you also take care of your school work.If you are not fortunate enough to get into the NBA,you still can get a scholarship,a degree.”

    Leonard will wrap up his trip by making a special appearance at the NBA Play-zone in Shanghai,an NBA-themed family entertainment destination.After that,he's back home to focus on the build-up to the new season.

    Shoppers in the UK are spending less money on toilet paper to save money, research has shown.

    Penny saving UK consumers choose cheaper products from discounters such as Aldi and Lidi rather than expensive alternatives.

    This has wiped 6% off the value of the soft tissue paper market in the UK. It has reduced from £1.19 billion in 2011 to £1.12 billion in 2015, according to a new report from market research company Mintel. Furthermore, the future of the market looks far from positive, with sales expected to fall further to £1.11 billion in 2016.

    In the last year alone, despite an increase in the UK population and a rise in the number of households, sales of toilet paper fell by 2%, with the average household reducing their toilet roll spending from £43 in 2014 to £41 in 2015.

Overall, almost three in five people say they try to limit their usage of paper – including facial tissue and kitchen roll    to save money. “Strength, softness and thickness remain the leading signs of toilet paper quality, with just a small part of consumers preferring more expensive alternatives, such as those with flower patterns or perfume,” said analyst Jack Duckett. “These extra features are considered unnecessary by the majority of shoppers, which probably reflects how these types of products are typically more expensive than regular toilet paper, even when on special offer.”

    While consumers are spending less on toilet paper, they remain particular about it when it comes to paper quality. One in 10 buyers rank toilet rolls made from recycled paper among their top considerations, clearly showing how overall the environment is much less of a consideration for shoppers than product quality. In a challenge for makers, 81% of paper product users said they would consider buying recycled toilet tissue if it were comparable in quality to standard paper.

Harry, the first camel to arrive in Australia in 1840, was an unlucky beast. He was imported from the Canary Islands by explorer John Horrocks. On an expedition (探险), Horrocks picked up his gun in order to shoot “a beautiful bird to be added to the collection.” Perhaps Harry was an ecologist —- he lurched (突然倾斜), and the gun discharged, shooting Horrocks in the face.

    Horrocks not surprisingly died of his injuries, and his treatments ordered Harry to be shot. The first importation of a camel into Australia came to naught.

    In 1860, 24 camels arrived in Australia to be part of an expedition by explorers Robert O'Hara Burke and William John Wills. It was an unlucky expedition. The pair made one mistake after another, and ended up eating most of their camels, before starving to death.

    Six years later, more than 100 camels and their Afghan minders, arrived in Australia. This time it succeeded and thousands more camels followed.

    Sir Thomas Elder set up the first camel studs (种畜场) in South Australia, while others were set up in Western Australia. This time the camels bred (繁殖) like wildfire. They were used for working, rather than exploring expeditions.

    The imported Afghan cameleers were just as hardy and vital, leading camel trains across the cruel interior (腹地) of Australia, where few dared to go. The camels carried heavy packs of wool and supplies and opened up the desert areas as none had managed to do before. The train that does this crossing today is called The Ghan, in their honor.

    Motorization put these camel trains out of business, and many camels were turned loose. The camels loved Australia, and multiplied in amazing numbers. What is to be done with them?

    Not surprisingly they have become quite a tourist attraction and you can take a camel ride in the desert as the Afghan cameleers once did. But the fact is that camels create quite a problem in areas where they have taken over, as they damage local vegetation, muscle out native animals competing for food, and create chaos when they wander into settled area.

    Most people agree that being a good driver means being safe and not aggressive on the road. One debate some people still argue, however, is who drives better: men or women? Although it's impossible to say that one gender drives better than another definitively, there are some noteworthy trends.

    Male drivers tend to have more accidents

    Data from the Insurance Institute for Highway Safety (IIHS) shows that male drivers tend to have more total accidents than females. The IIHS, an independent non­profit devoted to reducing car accidents, also found that 71 percent of all motor vehicle crash deaths in 2017 were males. Although the gap has narrowed, almost every year from 1975 to 2017, the number of male crash deaths was more than twice the number of female crash deaths, per the IIHS.

    Women might be less­confident behind the wheel

    Although male drivers have more accidents, other research shows women aren't "perfect" drivers, either. Researchers from the University of Michigan's Transportation Research Institute studied traffic accidents over 20 years and found that female drivers are more likely to run into a car driven by another woman than a man. The study, however, doesn't explain possible reasons for this pattern.

    One that they might consider testing in the future is that some research also shows women are less­confident behind the wheel than men. A study from UCLA exploring the relationship between new drivers' skills and different variables, including gender(性别), shows female students were less confident drivers than men.

    So are men better drivers than women?

    Gender is just one factor when it comes to safe driving, along with others such as age, and even the time of day people drive. One study shows that both genders have a greater accident risk when driving at night, but males still have a higher risk at all times of the day. Driving quality also changes based on location, too, as some states are more dangerous than others. Data from the National Highway Traffic Safety Administration shows that Wyoming, Mississippi, and Montana have high accident death rates, without regards to gender. It goes to show that everyone should learn and practice safe driving habits instead of worrying about who drives better.

Imagine reading a story titled "Pursuing Success." That would be an inspiring story, wouldn't it? Maybe—but maybe not. It might well be the story of someone whose never-ending chase for more and more success leaves them unsatisfied and incapable of happiness.

Though it isn't a conventional medical addiction, for many people success has addictive properties. Obviously, success goes with praise. To a certain extent, praise stimulates the neurotransmitter dopamine (神经递质多巴胺), which contributes to all addictive behaviors.

The desire for success may be born to human nature, but specialness doesn't come cheap. Success is tough work, and it requires bearing the cost of losing. In the 1980s, the physician Robert Goldman famously found that more than half of ambitious athletes would be willing to take a drug that would kill them in five years in exchange for winning every competition they entered.

Unfortunately, success is endless. The goal can't be satisfied; most people never feel "successful" enough. The high only lasts a day or two, and then it's on to the next goal. Psychologists call this the hedonic treadmill (快乐跑步机现象), in which satisfaction wears off almost immediately and we must run on to the next reward to avoid the feeling of falling behind.

People should get off the treadmill. But quitting isn't easy for addicts. For people hooked on substances, withdrawal can be a painful experience, both physically and psychologically, research finds that depression and anxiety are common among outstanding athletes after their careers end. Olympic athletes, in particular, suffer from the" post-Olympic blues."

Just like wine, success in and of itself is not a bad thing. Both can bring fun and sweetness to life. But both become bossy when they are a substitute for — instead of a complement (补充物)to — the relationships and love that should be at the center of our lives.
