Some people believe that a Robin Hood is at work, others that a wealthy person simply wants to distribute his or her fortune before dying. But the donator who started sending envelopes with cash to deserving causes，accompanied by an article from the local paper, has made a northern German city believe in fairytales (童话）

    The first envelope was sent to a victim support group. It contained €10,000 with a cutting from the Braunschtveiger Zeitung about how the group supported a woman who was robbed of her handbag； similar plain white anonymous (匿名）envelopes, each containing €10,000, then arrived at a kindergarten and a church.

    The envelopes keep coming, and so far at least €190,000 has been distributed. Last month, one of them was sent to the newspaper's own office. It came after a story it published about Tom, a 14-year-old boy who was severely disabled in a swimming accident. The receptionist at the Braunschweiger Zeitung opened an anonymous white envelope to find 20 notes of €500 inside , with a copy of the article. The name of the family was underlined.

    "I was driving when I heard the news,” Claudia Neumann, the boy's mother, told DerSpiegel magazine. “I had to park on the side of the road； I was speechless. ”

    The money will be used to make the entrance to their house wheelchair-accessible .and for a course of treatment that their insurance company refused to pay for.

     “For someone to act so selflessly, for this to happen in such a society in which everyone thinks of himself, was astonishing," Mrs. Neumann said. Her family wonder whether the donator is a Robin Hood character, taking from banks to give to the needy.

    Henning Noske, the editor of the Braunschweiger Zeitung, said： “Maybe it is an old person who is about to die. We just do not know. ” However, he has told his reporters not to look for the city's hero, for fear that discovery may stop the donations.

    It is a popular Internet thing to focus on the upside of being in your 30s, and it is nice to know how to do basic modern-human-being things like paying your taxes and cooking a simple meal. But it can be a less-encouraging story at work: People in their late 20s to early 40s tend to report lower levels of job satisfaction and higher levels of emotional exhaustion than other age groups, according to new research.

    There's an obvious reason: These tend to be the ages when people have young children at home, and the researchers did find that this group reported feeling increasingly crunched for time. But adding to that pressure, coworker support also tends to decline at this age. Some researchers interpret the findings:

    Support from co-workers probably decreases in midlife as peers compete for limited resources（promotion bottlenecks are often encountered during this career stage. Also, whereas younger co-workers are often hungry to make up new social networks, and older workers seek identity-affirming work experiences in their remaining tenure（任期）, mid lifers find it demanding enough just to maintain existing social networks. Meanwhile, time pressure likely increases as colleagues are all trying to enrich their own knowledge and experience.

    But the good news is that after about a decade of struggle, things start to pick back up again. Occupational psychologists say that happiness at work recovers when people reach their 40s, and that people in their 50s are more satisfied with their jobs than any other age group. Hang in there, 30-somethings-soon you will be older, but at least work will meet less frustration（挫折）!

    On April 2, we said goodbye to Tiangong I, China's first space lab. According to the China Manned Space Agency（中国载人航天）, Tiangong I re-entered the Earth's atmosphere （大气层）and fell into the South Pacific Ocean.

    There are many spacecraft that are still in orbit above the Earth. They are flying at heights ranging from 300 to 1,000 kilometers. After finishing their trips, they will all re-enter the Earth's atmosphere like Tiangong I.

    There are two types of re-entries：controlled（受控的）re-entry and uncontrolled re-entry.

    Some satellites（卫星）and manned spacecraft come back to the Earth in a controlled re-entry. Scientists calculate（计算）the path of the falling spacecraft and its speed. They can guide the spacecraft to fall in a chosen area. In 2017,Tianzhou I, China's first cargo（货运）spacecraft, was directed to fall in the South Pacific Ocean.

    Some spacecraft may have problems while in space, or are simply no longer usable after a certain amount of time.  These craft come back in an uncontrolled re-entry.  It is hard to tell when and where these spacecraft will fall until the last few hours. The US space station Skylab came back partially uncontrolled in 1979. Parts of the station fell in western Australia, but no one was injured.

    During re-entry, most of the spacecraft will burn up while passing through the Earth's atmosphere. Only a small amount of the debris（碎片）will reach the ground.

    The debris typically ends up falling into the ocean, China Daily reported. Tiangong I weighs about 8.5tons. The amount of debris that falls to the Earth might be about 1 to 1.5 tons, the Beijing News reported.  That is about the same weight as a car.

    From 100 years of Bauhaus to 350 years since Rembrandt's death, a host of landmark art events and exhibitions are open around Europe this year.

    John Ruskin 200th England

    This year is also the bicentenary (200周年纪念) of the birth of John Ruskin, the art critic, writer and reformer. There are exhibitions throughout the year at Brantwood, his former home in Cumbria, on topics from his clothes to his interest in geology and his legacy in Japan. On Ruskin's birthday, 8 February, there is a free public lecture on his love of trees at Oxford University Museum of Natural History and an evening of readings and music at the Royal Academy, London.

    Rembrandt 350th The Netherlands

    It is 350 years since the death of Rembrandt van Rijn. There is a year-long programme of events in nine Dutch cities, focusing on Rembrandt and the Dutch golden age. In Amsterdam, the Rijks Museum (15 Feb-10 June) will display all of its 22 paintings, 60 drawings and 300 engravings – the biggest Rembrandt collection ever seen in a single exhibition.

    Bauhaus 100th Germany

    Germany is celebrating the centenary of Bauhaus, the revolutionary art school founded by Walter Gropius in 1919. The opening festival is already under way at the Berlin Academy of Arts, with a programme of concerts, plays and virtual reality installations (until Thursday 24 Jan). But visitors are encouraged to explore beyond the capital throughout the year on a self-guided road trip.

    Renoir 100th France

    August Renoir died 100 years ago in December. The Eau et Lumière Association, which has created 12 "Impressionisms Routes" linking sites that inspired 12 European impressionist painters, has declared 2019 to be Renoir Year. It hopes to attract more art lovers to attractions on the Renoir Route—visitors to Paris could try the Museum of Montmartre and Renoir Gardens, where he once lived, or the Musée de la Grenouillère in nearby Croissy-sur-Seine, where he painted river scenes.

    Like many other people who speak more than one language, I often have the sense that I'm a slightly different person in each of my languages­more confident in English, more relaxed in French, more emotional in Czech. Is it possible that, along with these differences, my moral compass (指南针) also points in somewhat different directions depending on the language I'm using at the time?

    Psychologists who study moral judgments have become very interested in this question. The findings of several recent studies suggest that when people are faced with moral dilemmas (困境), they do indeed respond differently when considering them in a foreign language than when using their native tongue.

    In a 2014 paper led by Albert Costa  volunteers were presented with a moral dilemma known as the "trolley problem": imagine that a runaway trolley is moving quickly toward a group of five people standing on the tracks, unable to move. You are next to a switch that can move the trolley to a different set of tracks, therefore sparing the five people, but resulting in the death of one who is standing on the side tracks. Do you pull the switch?

    Most people agree that they would. But what if the only way to stop the trolley is by pushing a large stranger off a footbridge into its path? People tend to be very hesitant to say they would do this, even though in both situations, one person is sacrificed to save five. But Costa and his colleagues found that presenting the dilemma in a language that volunteers had learned as a foreign tongue dramatically increased their stated willingness to push the sacrificial person off the footbridge, from fewer than 20% of respondents working in their native language to about 50% of those using the foreign one.

    Why does it matter whether we judge morality in our native language or a foreign one? According to one explanation, such judgments involve two separate and competing ways of thinking­one of these, a quick, natural "feeling," and the other, careful deliberation about the greatest good for the greatest number. When we use a foreign language, we unconsciously sink into the more careful way simply because the effort of operating in our non-native language signals our cognitive (认知的) system to prepare for difficult activity.

    An alternative explanation is that differences arise between native and foreign tongues because our childhood languages are filled with greater emotions than are those learned in more academic settings. As a result, moral judgments made in a foreign language are less filled with the emotional reactions that surface when we use a language learned in childhood.

    There's strong evidence that memory connects a language with the experiences and interactions through which that language was learned. For example, people who are bilingual (双语的) are more likely to recall an experience if reminded in the language in which that event occurred. Our childhood languages, learned in the middle of passionate emotion, become filled with deep feeling. By comparison, languages acquired late in life, especially if they are learned through limited interactions in the classroom or dully delivered over computer screens and headphones, enter our minds lacking the emotionality that is present for their native speakers.

A school district in Michigan has banned all backpacks from school buildings, in response to growing safety concerns. 

Flint Community Schools announced last week that backpacks would be banned and the ban would be in place for the rest of the school year. The new policy went into effect on Monday. 

"We are doing all that we can to create a safe and secure environment for our scholars, families, teachers and staff," Superintendent (主管) Kevin Jones wrote in a letter posted on the school district's website. 

Jones cited growing threatening behavior happenings across the country, including weapons being brought to schools, as the reason for the backpack ban. 

"Backpacks make it easier for students to hide weapons, which can be taken apart and harder to identify than hidden in pockets, inside books, or under other items," he said. 

Following the shooting at Robb Elementary School in Uvalde, Texas, last May, where 19 students and two teachers died, schools began taking policies requiring students to use clear backpacks. However, Flint Community Schools have gone a step further and banned clear backpacks from school buildings, with the superintendent saying that it doesn't resolve the issue. 

"By banning backpacks altogether and adding an increased security presence across the district, we can better control what is being brought into our buildings," Jones said. 

Students are allowed to store personal items like wallets, keys, hygiene products (卫生用品) and phones in small purses, bring lunchboxes or place their gym clothes in clear plastic bags, all of which will be subject to searches. 

If a student brings a backpack to school, parents or guardians must pick it up from the school, according to Jones. 

The Flint Board of Education, the district's administration and headmasters approved the policy change, Jones said, adding that the district received support from the Flint Police Department.
