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.

    Scottish pupils recently were part of a new scheme that allowed them to take their exams online. Those examinations provided a glimpse of the future in May when 120 candidates in 10 centers in Scotland sat in front of computers to take a multiple-choice online exam. Although candidates were using a computer mouse instead of a pen, in all other ways the exam was the same as normal.

    Exam rooms were set out to ensure that only the candidates and the teachers were able to see the individual screens. The online answers were sent directly to a safe area. According to the students at St Ninian's in East Renfrewshire who took an online French exam, it was definitely the most motivated they had ever felt when taking an exam.

    “I could go as fast as I wanted to, rather than as slow as everyone else wanted to,” said one. “It was better than looking back and forth between the questions,” said another. One pupil even described it as fun.

    Their head teacher, Dorothy Graham, was not so surprised, “They are so used to doing things on computers that it seems natural for them. The boys liked it because they didn't have to worry about how neat their work was.” The only things that worried her were power cuts and systems' crashing.

    It's thought that online exams could be the norm (常态) in about five years. However, last year there were warnings about computerizing exams in England and Wales. It's thought that it could be unfair to some students if they come from homes without access to a computer.

    The loud continuous noise of the cars or the sound of a plane can force its way into the deepest forest, yet it's not only humans that ere bothered by the noise.

    Bioacoustician Bernie Krause has been studying the effect of noise pollution on wildlife, and has come across some interesting behaviors, especially among animals that communicate by vocalization（发声）, like humans. Birds use sound to communicate, but in noisy places, these animals have to shout over the natural noise to be heard.

    Krause mentions a study of nightingales to clarify what he means. The birds responded to traffic noise by singing louder and louder until they actually went beyond noise pollution standards in the city. To belt out (sing loudly) their songs, they increased their lung pressure fivefold, but scientists state that this is not dangerous for the birds themselves.

    Studies show that sudden noise can cause certain birds to leave their nests, exposing the young to their enemies. One study also showed that songbirds that nested close to busy motorways were much less productive than those that nested farther away. Mammals（哺乳动物）too are affected. A recent study showed that nursing caribou responded to plane noise by not producing enough milk to feed their young.

    In some cases noise pollution can actually help some animals while harming others. Toads（蟾蜍）and frogs are known to vocalize in synchrony（同步；同步方式）so that no predator (their enemies) can zero in on them. Krause found that when planes flew overhead and disturbed the toad's song, they lost their synchronicity, and it took them 45 minutes to get it back again. That gave their natural enemies plenty of time to find and catch individual toads by sound.

    According to Kruse, “Not only will noise pollution bother wildlife, but it won't help our lives either.”

    Teachers' Day is, interestingly, not celebrated on the same day all over the world. In some countries it is marked by a holiday, in others it is a working day.

    International Teachers' Day is celebrated on October 5. Being held ever since 1994, it is in honor of teachers' organizations worldwide. Its aim is to encourage supports for teachers and to meet the needs of students.

    China In 1939, Teachers' Day was set for August 27, Confucius' birthday. In1951, the celebration was stopped. However, it was founded again in 1985, and the day was changed to September 10.

    India   Teachers' Day is celebrated on September 5 in honour of Dr. Sarvepalli Radhakrishnan, the second president of India, whose birthday falls on that day.

    Russia ― In Russia, Teachers' Day was celebrated on the first Sunday of October between 1965 and 1994. Since 1994, the day is observed on the October 5, just the same day as World Teachers Day.

    The US   In the US, Teachers' Day is non-official holiday. It is celebrated on the Tuesday of the first full week of May. A number of activities are organized in schools to honor teachers. The celebrations can continue for the whole week of May.

    Thailand   In Thailand, National Teachers' Day is celebrated every year on January 16. The first Teachers' Day was held in 1957. The day is a holiday in schools.

    Here are some professions Americans consider to be the most honest. Maybe the rest of us can learn from what these people do to establish good relationships with others.

    MEDICAL DOCTORS

    Jack Jacob, Age: 44, Fountain Valley, California

    I try to introduce myself in a pleasant way. I sit down. I don't stand. I make good eye contact with the patient and his or her family. Communication skills are key, as well as showing understanding and availability. For a physician, the most rewarding thing is when someone who has seen your work chooses you.

    ENGINEERS

    Chrissy Keane, Age: 41, Crofton, Maryland

    I don't know that being an engineer means you are automatically trustworthy. However, I do think that most engineers like to follow rules and be organized. They tell you what they think, whether you want to hear it or not. Those are important elements in building trust.

    POLICE OFFICERS

    G. M. Cox, Age: 64, Fort Worth, Texas

    As a police officer, I have the best interests of the people I serve in my heart and in my actions and I'm going to treat everyone the same way. I always want to go up to people and speak to them with respect. Don't talk down to them. You have to establish and maintain that trust. Be equal!

    Recently a movement was launched by Charity Cycling UK to raise awareness of dooring after discovering that many people don't know what it is. Dooring is when a driver or passenger opens the door into another road user—typically a cyclist—without looking for other road users.

    Cycling UK Chief Executive Paul Tuohy told Gloucestershire Live: "Some people seem to see car dooring as a bit of a joke, but it's not and can have serious consequences. Cycling UK wants to see great awareness made about the dangers of opening your car door carelessly，and people to be encouraged to look before they open."

    The charity says 2,009 of the 3,000 injuries happened to cyclists, resulting in five deaths but says this might not be the full extent of the danger.

    Cycling UK says not all car dooring incidents will be attended by police, so the charity has written to transport minister Jesse Norman calling for a public awareness campaign urging all car occupants, not just drivers, to look before opening vehicle doors. One of the ways the charity suggests is the "Dutch reach", where people leaving a vehicle reach over and use the non-door side hand to open the door.

    Cycling UK also suggests harsher laws and advice on safer road positioning for people who cycle.

    Mr Tuohy said: "In the Netherlands they are known for practising a method，known sometimes as the 'Dutch reach', which we think could be successfully encouraged in the UK."

    "Cycling UK has written to the Department for Transport asking them to look into this, and highlight the dangers of "car dooring" through a public awareness THINK style campaign."

    If you're really concerned about opening a door into the path of a cyclist coming behind you, consider using what's known as the "Dutch reach" to open the door. That will naturally turn you in your seat and give you a much better view of what's coming up alongside the car.
