A German fisherman named Konrad Fischer found the brown bottle near Kiel, Germany. He said he nearly threw the bottle back into the water after pulling it out of a fishing net. Then he noticed something inside.

    The bottle in good condition contained a Danish postcard with two German stamps, dated May 17, 1913. Although dampness had made most of the writing illegible（字迹模糊的）, the readable part of the message asked whoever found it to return it to an address in Berlin. It even contained two stamps to pay for postage.

    From the address, researchers found that the postcard was written by a man named Richard Platz, who was 20 years old when he wrote the message. While he was hiking on the Baltic coast with a nature appreciation group. he threw the bottle into the sea. Then the researchers began a search for any living relatives of his. Sure enough, they were able to find his 62-year-old granddaughter, Angela Erdmann, who still lives in Berlin.

  “It was almost unbelievable,”Erdmann said upon being presented with her grandfather's bottle and message.“That was a pretty moving moment. Tears rolled down my face."

    Erdmann never knew her grandfather，who died in 1946，but says that the discovery of the bottle has made her want to learn more about him.

    The bottle remained on display at the International Maritime Museum in Hamburg until May 1st. After that, the researchers examined the postcard and tried to figure out the meaning of the rest of the message.

    Previously, the oldest message found in a bottle spent nearly 98 years at sea and was discovered in April 2012, according to Guinness World Records.

    Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the "on/off" button on the TV. But some buttons are actually fake, like the "close" button on a lift.

    Many people are in the habit of pressing the "close" button because they don't have the patience to wait for the lift doors to shut. But lifts' "close" buttons are a complete scam (骗局), at least in the US-the doors will not close any faster no matter how hard you press.

    It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

    But to normal lift riders, the buttons aren't completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control.

    "Perceived (能够感知的) control is very important. It reduces stress and increases well-being," Ellen J. Langer, a psychology professor, said, "having a lack of control is associated with depression（沮丧）."

    Experts have revealed that a lot of buttons that don't do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workplace.

    Pedestrian(行人) crosswalk buttons don't live up to their names either. Pressing them used to help make the traffic signals change faster, but that was before computer-controlled traffic signals were introduced.

    But psychologists found it interesting that even when people are aware of these little "white lies", they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

    "That habit is here to stay," John Kounios, a psychology professor, said. "Even though I have real doubts about the traffic light buttons, I always press them. After all, I've got nothing else to do while waiting. So why not press the button in the hope that this one will work?"

    When it comes to bringing up children, everybody agrees that it is not an easy task. Every parent watches eagerly the child's acquisition (学会) of each new skill — the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting (吸引人的) to hurry the child beyond his natural learning speed, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to learn something too early. A young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning chances, he loses his natural enthusiasm for life and his desire to find out new things for himself.

    Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are strict with the time of coming home at night or being on time for meals. In general, the controls show the needs of the parents and values (价值观) of society as much as the children's own happiness.

    When it comes to the development of moral standards (道德标准) in the growing child, consistency (前后一致性) is very important in parental teaching. To say "No" to a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practice what they preach (说教), their children may grow confused and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent cheated.

    A sudden realization of a big difference between their parents' principles and their morals can be a dangerous disappointment.

    Many children are interested in dinosaurs (恐龙). If you have a child who loves dinosaurs, then here is some good news for you. There is an exhibition of dinosaurs at the Philip J. Currie Dinosaur Museum in Wembley, Albert A. You can plan a family road trip there. Give your child a surprise and you'll enjoy your time there as a family.

    Sitting just 19 kilometers west of Grande Prairie, the Philip J. Currie Dinosaur Museum was opened in 2015 and has collections that include fossils（化石）of sea animals, art works from different dinosaurs, a large family theater, as well as an outdoor discovery fossil walk, a large outdoor playground and the onsite Dine-O-Saur restaurant. Experience the dinosaurs' world like never before as you watch dinosaurs coming alive in movies. Learn about how these animals lived and breathed.

    John George, 60, remembers that he lived a wonderful life in the Detroit neighborhood where he grew up. "We knew all our neighbors." George told Detroit's Metro Times. "On Christmas Eve, we'd all go to midnight Mass, and there'd be 300 people in our house at one o'clock to about five in the morning. The folks were just really good, hardworking people."

    By the'80s, however, the old neighborhood changed. Due in part to economic downturns and drug abuse, well -kept homes had been abandoned and kindly neighbors had fled to the suburbs(郊区). But not George. "Living in any city, it's like being in a relationship," he told Reader's Digest. "Some days are better than others. But it was my home. And when I saw it becoming worse, I had two choices: I could leave, or I could stay and fight. I chose the latter."

    When the abandoned home behind his turned into a worn-out place, the father of two grabbed some boards and nails and began boarding up the house. After two neighbors stopped to ask what he was doing, they decided to help, with great results.

    That's how it all got started. In the 30 years since that first home rescue, an army of approximately 182,000 volunteers, along with private donors, has helped George pull down around 300 abandoned homes, mainly in die poorer Northwest area of Detroit. They've also secured 400 - some homes by boarding them up. They've painted and repaired nearly 900 homes and built over 100 from scratch. According to Forbes, more than 1,000 Detroiters have been housed as a result of their work.

    And there's Halloween. In Detroit, October 30 was known as Devil's Night, a period when all hell break loose in the form of crime and vandalism (破坏公物). In response, George created a citizens' patrol(巡逻)that would take to the streets, keeping an eye on illegal behavior. He named it Angels' Night What began with 12 neighbors on patrol in 1990 has grown to more than 60,000 citywide.

    George's inspired ideas have not gone unnoticed by the city he loves. Others are buying into it. There's a trend of younger homeowners coming in.

    Tiredness, coughing, a runny nose and a sore throat—among all sicknesses there is probably none more common than the flu (流感), which we all get now and then. However, bird flu is a completely different story.

    In 2003, the H5N1 bird flu swept across 15 countries, including China, with sufferers reporting chest pain, difficulty breathing, fever and severe coughing. More than 600 people were infected, and about 60 percent died. Now, another type of bird flu hit Shanghai and three neighboring provinces, and this time the virus is called H7N9. By the afternoon of April 11, the new virus had taken nine lives out of 35 infected, according to Xinhua News Agency.

    The "H" and "N" in the virus' name refer to two kinds of proteins (蛋白质) on the surface of the virus. Any change of the numbers of the two proteins indicates a new mutation(变异). Most of the mutations only affect birds, such as chickens and pigeons, and don't normally spread to humans. But once they do, the results can be disastrous.

    "Any time an animal influenza virus crosses to humans, it is a cause for concern, " Malik Peiris, virologist (病毒学家) at the University of Hong Kong, told Nature magazine. Take the SARS epidemic (传染病) in 2003 as an example. The virus behind the disease is thought to have jumped to humans from animals. The virus was a complete "stranger" to human bodies, which hadn't developed an immunity (免疫力) against it.

    But there is something more about the new H7N9 bird flu. Unlike the H5N1 bird flu, which causes severe sickness in birds, the H7N9 has been evolving under the radar(悄悄地) since it travels between birds without causing noticeable illness. That makes it difficult to keep track of the disease.

    The good news is that there's so far no sign that the virus is spreading from person to person. But since there is no vaccine (疫苗) for the disease yet, the World Health Organization recommends that you wash your hands after meeting with sick people and before and after you eat or prepare food, and they also suggest avoiding contact with birds or their eggs.
