As I stood in the return line and watched people, I became extremely impatient. My daughter had got four Barbie dolls and two identical Cabbage Patch Kids on Christmas, so I was eager to return toys that she didn't need. Suddenly a strong idea came to me. I eyed the lady in front of me with three small girls on her leg. The family looked poor. The children were without coats, and they had dirty faces and hair. “You are ready to get out of here, aren't you? Give her the things you want to return,” the still voice spoke. “Give them to her? These are mine. I'm not giving her my stuff,” I argued. I swallowed the urge that threatened to escape my lips when the voice spoke again. “Give her the toys.” I was familiar with the voice. I know I couldn't argue with that voice.

    I sighed and tapped the lady on the shoulder. “Ma'am,” I cleared my throat. She looked at me with kind, tired eyes surrounded by wrinkles. “Yes?” she asked. “Would your little girls like to have these toys?” I pointed to my basket full of returns. “Would your children like to have them?” She was speechless, and I swore that tears were about to well up in her eyes. “You'd be doing me a favor. I can't stand in this line in a moment longer.” “You have no idea,” she shook her head. “You have no idea what that means to me.”

    I started loading her basket as the excited girls watched. “Merry Christmas,” I said, “God bless you.” She replied as I nodded and exited the line. I didn't want to go the Walmart that day, but I went. I didn't want to give the lady my kid's toys, but I did. Sometimes doing what we don't want to do is exactly what we're supposed to do.

    Miles was born in Alton, a city on the Mississippi River in Illinois on May 26, 1926. Miles's father was a dentist, while his mother was a music teacher. Miles had a good childhood, catching fish and riding horses with his older sister and younger brother. He was known as a naughty boy in school.

    He recalls his story, “By the age of 12, music had become the most important thing in my life.” His mother, a violinist herself, dearly wanted her son to play the violin. But brass (铜管) was Miles's calling, and he remembers arguments between their parents as his dad overruled her to fight his son's corner. He received his first trumpet (喇叭) in 1935 and began weekly music lessons with his father's friend Mr. Elwood, his life-long teacher.

    Talking about his school days, Miles said that Mr. Buchanan was the biggest influence on his life. He was the person who took Miles all the way into music at that time. He wanted to be a musician that he had dreamed.

    When he was 16, Miles met his girlfriend, Irene Birth. Although she was a beautiful young woman in many ways, it was her easy-going character that attracted Miles. At the weekends, Miles and Irene would take the bus over the Mississippi River to St Louis to watch movies and go dancing. Although Miles was too shy to really enjoy dancing, he always felt confident when he danced with Irene.

    When he turned 17, she persuaded him to ask for a job in his band—Eddie Handle's Blue Devils. It worked. Joining the band was a breakthrough for Miles, and marked the time when he first began to write and arrange music.

    Rain beat against the window, matching my mood. I should have known that my new job at the hospital was too good to be true. Throughout the day, rumors (传言) warned that the newest employee from each department would be laid off. I was the newest one in the training department.

    My boss appeared. “You probably know we're cutting back,” he said. “Administration wants us to offer outplacement classes to help those employees find other jobs, showing them how to act in an interview, for example.” “Fine,” I answered unwillingly, not knowing what else to say.

    I decided to go home early that day. In the hall, I met the lady who brought us cookies every Friday. She was a little woman with gray hair. Only her head and the top of her green apron were visible over the cart (小车) loaded with cleaning supplies. At least she had a job!

    At the final meeting, laid-off workers formed a line at the door. A colleague whispered, “I can't believe our Cookie Lady is being laid off. We'll miss her as much as we'll miss her cookies.” When the colleague spoke to her in Spanish, I knew my classes would be useless for her and I realized how much better off was than this poor woman.

    I decided to do something for her. I wrote to a newspaper expressing how I felt about the unselfishness of the Cookie Lady who needed a job. A few days later, my article appeared in the newspaper and the Cookie Lady was allowed to stay in her position. On the same day, I received a letter, which seemed so unlikely that I read it twice. “An editor of a local magazine likes your piece and wants you to call her next time you're looking for work …”

    It is a psychological strategy that all parents will be familiar with: instead of scolding an misbehaving child, focus instead in rewarding them for good behaviour.

    Now the idea is well received outside the nursery, with implications for everything from recycling clothes to policing.

    Consumers end up with piles of unwanted clothes. Every year in the UK, 300,000 tonnes ends up in landfill — 235 million individual items.

    Now however, apps such as ReGain, Regive and Stuffstr are making it simpler — and more worthwhile — for people to return their unwanted clobber.

    The ReGain app can be used to find one of 20,000 drop-off points. In return, the diligent consumer earns rewards such as discount coupons for high street retailers. Stuffstr works in partnership with John Lewis to help people get cash in return for unwanted items from the chain.

    “Possibly the one prediction that we economists get right is that if you incentivise (激励) a behaviour, you will get more of it,” says Dr Matthew Levy, a lecturer in economics at the London School of Economics.

    He cites research, including his own, showing that financial incentives encouraging regular exercise, stopping smoking and losing weight effectively promote healthy behaviours and that there is no backlash when the incentives are removed.“If anything, the incentives can be used to jump-start a healthy habit that keeps going,”he says.

    In the four months after its launch, the ReGain scheme received almost 17,000 parcels containing 47 tonnes of used clothes and shoes, of which 95% could potentially be reused, according to its founder Jack Ostrowski.

    “We need to find a way to influence behaviour, and discount coupons help,” he says. The platform is also working with brands and retailers to find ways to divert used clothes from landfills and into the production of new clothes, he adds.

    Other reward schemes have had success in encouraging behavioural change.

    When police in Canada issued “positive tickets”— coupons for free food or movie tickets — to reward good behaviour among young people, they reported an almost 50% drop in youth-related service calls.

    “My officers would say' In the old days we'd drive up in the police car and the kids would run away from us, now they run to us'.”

    In a similar venture, Hull city council have announced plans to launch a digital reward token — the HullCoin — that can be earned by volunteering and spent at local retailers.

    Elsewhere, a study on the recruitment of health workers in Zambia found that highlighting economic incentives during the recruitment process caused future employees to be more motivated and task-focused.

    “Obviously different groups are motivated by different factors,” says Ostrowski. “For some, the feel good factor is enough, and for others, that reward stimulus is required.”

    How many times have you come back and felt terribly tired, feeling like your head is going to explode? Sounds familiar, right? Well, there are several ways to reduce the frequency of headaches, and those are: eating balanced diet through the day, making sure your body is well hydrated (保持身体水分);getting some exercise to remove the negative energy, like helping yourself with a short massage (按摩)on your head. However, preparing an easy recipe will instantly put a smile on your face after your workday.

    You will need these simple ingredients (配料)to prepare the magical drink which will stop your headache: Lemon juice; 2 teaspoons of salt (preferably high quality salt); 1 cup of water.

    Directions:

    Squeeze 2 lemons. Pour the lemon juice into a cup and add 2 teaspoons of salt. Mix the two ingredients. Add a cup of water to the content. Drink the mixture quickly.

    How will this drink work and what are the benefits of its ingredients?

    Salt: Here is what salt does for your body: regulates your blood sugar, balances the sugar levels; benefits nerve cells for communication and information processing; obtains acidity from your body's cells, especially brain cells; works as a strong anti-stress element for the body; adds energy in your body's cells.

    Lemon Juice: This excellent juice, full of vitamin C and anti-poisons, will release all poisonous substances from your body and give you a sense of lightness. Here's how the lemon will help you ease your headache and maintain well-being to your whole body: balances the pH levels in your body; protects your immune system; nourishes your brain and nerve cells; reduces inflammation (炎症)in your whole body (the headache is a type of inflammation, so the lemon juice fights against it).

    Water：

    Water is important for hydrating your whole body, including your head. Many of your daily headaches may be caused by dehydration (脱水), so keep in mind that you should drink plenty of water throughout the day.

    Addyson Moffitt is an 8-year-old from Kansas City, Missouri. Maurine Ghelagat is a 9-year-old from a village in Kenya called Bartabwa. It might not seem as if the girls have much in common, but when they met at a dinner two years ago, in Kansas City, they immediately hit it off.

    "We had this one little red ball to play with," Addyson told TIME for Kids. "We didn't have any electronics or phones, no iPads or TV. It was just us playing." Addyson and Maurine still keep in touch now.

    The dinner was hosted by the nonprofit group World Vision International, which builds wells, pipelines, and rain catchers in communities where people find it hard to get clean water. Addyson, was at the dinner because her family supports World Vision. Maurine was there because her village had been without clean water. World Vision fixed that by building a water station there.

    "People helped Maurine so she could have clean water, and kids are dying because they don't have it," Addyson says. "I want to help."

    Races are one way World Vision raises money to pay for its water projects. Runners run a race, often a 26-mile marathon or 13-mile half marathon. They ask people to support them by donating(捐赠) to World Vision.

    Addyson decided to run the 2017 Kansas City Half Marathon for World Vision. At age 7, she was one of the youngest-ever runners in the race, and had to get special permission to take part.

    Addyson spent four months training with her parents, waking up before 6 a.m. to run. Meanwhile, she started fundraising(募捐)by asking friends to make donations as birthday presents and clearing tables at a restaurant for tips.

    By October 2017, when Addyson ran the race, she'd raised more than $20,000. She's the youngest person in World Vision history to raise more than $10,000. In 2018, she ran again and raised $36.000.

    But Addyson's work is not finished. "My goal is for every kid to have clean water," she says.
