He was the baby with no name. Found and taken from the north Atlantic 6 days after the sinking of the Titanic in 1912, his tiny body so moved the salvage (救援) workers that they called him “our baby.” In their home port of Halifax, Nova Scotia, people collected money for a headstone in front of the baby's grave (墓), carved with the words: “To the memory of an unknown child.” He has rested there ever since.

    But history has a way of uncovering its secrets. On Nov. 5, this year, three members of a family from Finland arrived at Halifax and laid fresh flowers at the grave. “This is our baby,” says Magda Schleifer, 68, a banker. She grew up hearing stories about a great-aunt named Maria Panula,42, who had sailed on the Titanic for America to be reunited with her husband. According to the information Mrs. Schleifer had gathered, Panula gave up her seat on a lifeboat to search for her five children -- including a 13-month-old boy named Eino from whom she had become separated during the final minutes of the crossing. "We thought they were all lost in the sea," says Schleifer.

    Now, using teeth and bone pieces taken from the baby's grave, scientists have compared the DNA from the Unknown Child with those collected from members of five families who lost relatives on the Titanic and never recovered the bodies. The result of the test points only to one possible person: young Eino. Now, the family sees no need for a new grave. "He belongs to the people of Halifax," says Schleifer, "They've taken care of him for 90 years."

    Every year, billions of kilograms of fresh produce are wasted in the United States. Meanwhile, millions of poor Americans go hungry, without access to healthy and affordable meals. Evan Lutz, CEO and founder of Hungry Harvest, was inspired to act after seeing extreme poverty in areas of Baltimore, Maryland. He wants to reduce the so—called food waste in that area. His work is to make sure no food goes to waste and no person is ever hungry in America. And he combines that goal with a love for business.

    Hungry Harvest is a business which collects and sells fruits and vegetables that most food companies will throw away. Everything doesn't grow the same way on a farm. But all that is too big or too small gets thrown out. That is why everything in a grocery store looks similar. Hungry Harvest will box those imperfect ones and deliver them to customers once a week.

    For every purchase, Hungry Harvest delivers healthy food to people in need. Hungry Harvest has recovered 300,000 pounds of produce to date and provided 100,000 pounds to those in need.

    Lutz established Hungry Harvest in 2014.Its success depends on team work. Every week on Monday or Tuesday they will decide what will go into the next week's box by calling up packing houses and wholesalers to see what they will normally throw away that week. They then place the order. The last step ls to send goods to customers.

    In January 2016,Lutz appeared on the American business competition television show "Shark Tank" and got even more than he expected: $100,000.Lutz is using the money to expand. Actually, more than six billion pounds is wasted each year due to "ugly" surface. Hungry Harvest is on the way to saving more food from going to waste and feeding hungry families.

    It was not yet eleven o'clock when a boat crossed the river with a single passenger who was lucky to be able to cross the river at that unusual hour by promising to pay some extra money. While the youth stood in the light place searching his pockets for money, the boatman lifted a lamp, with the help of which, together with the newly risen moon, he took a careful look at the stranger. He was a young man of about eighteen years, clearly country brought up, and was, as it seemed, on his first visit to town. He was wearing a rough grey coat, which was in good shape, and which had seen many winters before this one. The jacket under his coat was made of leather and trousers fitted tightly to a pair of strong legs; his stockings of blue yarn(毛绒) must have been the work of a mother or sister, and on his head was a hat, which in its better days had perhaps protected the grayer head of the young man's father. In his left hand was a walking stick, and on his strong shoulders hung a leather bag. Brown hair, well-shaped features, bright, cheerful eyes were nature's gifts. The youth, whose name was Robin, paid the boatman, and then walked forward into the town with a light step, as if he had not already traveled more than thirty miles that day. As he walked, he looked around as eagerly as if he were entering London or New York instead of the little city in New England.

    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.”

Rosie, a first-year university student in Beijing, entered a classroom for her oral English exam and slid her topic across the table to Joe, a foreign teacher. My Story, it read. "In middle school, my classmates laughed at me for having deaf-mute parents," she began softly. "From that moment on, I decided not to tell anybody. But today…"

It's widely considered taboo(忌讳) in Chinese to discuss the details of an unhappy family life with anyone other than very close friends. However, as Joe has noticed, many Chinese students appear surprisingly comfortable discussing emotional moments from their lives when they speak with foreign teachers in a language different from their own.

"Speaking English," one of his Chinese students told him, "I feel like another person." When speaking Chinese, he is kind of reserved; in English class, he is more open. English, to the Chinese speaker, may be like a mask, creating a buffer(缓冲物)between speaking the truth and the listener's reaction. Students focus on how to speak rather than what is being said. If there's a misunderstanding, English can take the blame.

Another reason why Chinese students are more comfortable sharing their secrets during English class may be the distinct approach to teaching used by their foreign teachers. "I always try to come to each student, make eye contact, have a 20-second conversation and see how they are doing," Joe said. Classes taught by Chinese teachers, in contrast, are more formal. Many students said they had never been asked their opinion in class.

Rosie's English vocabulary is now extensive, but she still can't find the words to describe her feelings towards the English language. "English makes me feel I am different," she said. "English is beautiful."
