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.

    There are a number of reasons that can be given as to why children should be taught swimming at a young age. If your child knows the basic swimming skills, you can be at peace when your child is near the water. If you are in the process of teaching your child how to swim, then here are some points that you should keep in mind.

    Help your child pick a bathing suit. If you child wants to wear bathing suit and get wet then it is certain that your child will be able to handle the water.

    If the pool has steps, then it is great. Start from these to help your child gain some confidence. You should make sure that there is one place in the pool where your child can be left safely.

    The best way to teach your children to swim is to make them join swimming classes. In this way, you will be at peace because there is a professional trainer around your children who can teach them all the tricks of swimming. You can join in the parent-child lessons to make your child feel comfortable. If your child is a bit older, then get permission and sit by the pool to watch him/her learn. When you get your child admitted to swimming classes, make sure that the lessons go according to the swimming goals that you have set for your child.

    Swimming is a fun activity and you can make it easy for your children to understand and coordinate(协调)the movements of their arms and legs will take some time. But, with regular practice and training this can be overcome. So, start with the basics and be around your children when they are learning how to swim. Once they know how to swim, then you can be at peace when they play around the water.

    So what is rewilding?

    Imagine our natural homes growing instead of shrinking. Imagine species (物种) diversifying instead of declining. That's rewilding. Rewilding is ecological restoration. Rewilding offers hope for wildlife, humans and the planet.

    Why is rewilding important and necessary?

    Our natural ecology is broken. The places where you would expect wildlife to exist have been reduced to wet deserts. The seabed has been destroyed and there have been no living creatures any more.

    Our wildlife is disappearing. Many wonderful species have declined over the past century. We've lost more of our large animals than any European country.

    We need keystone species. These vital species, including top predators (食肉动物), drive ecological processes. Their loss has worsened our living systems.

    Nature looks after us. Good natural ecology can provide us with clean air and water, prevent flooding and store carbon. Rewilding can leave the world in a better state than it is today.

    What are challenges?

    As a long-term project, our "rewilding britain" has its challenges. Many people are not interested, because we have got used to the lack of native forests. Many farmers oppose the idea. They thought it a crazy idea to bring back predators because they would start killing farm animals. It takes time to educate them. Above all, we need money! So we need your help!

    Help us bring back living systems and restore wild nature!

With your help we can…

    Open up new chances for rewilding and push for change.

    Life is difficult.

    What do you think about life? Maybe most people say that life is difficult. But life is no longer difficult once we truly understand and accept it. Most people do not fully see this truth. Instead, they complain about their problems and difficulties as if life should be easy. It seems to them that their difficulties represent a special kind of suffering especially forced upon (强加于) them or their families, their class, or even their nation.

    What makes life difficult is that the process of facing and solving problems is a painful one. Problems, depending on their nature, cause us sadness or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.

    Yet, it is in this whole process of solving problems that life has its meaning.

    Problems are the serious test that tells success from failure. When we desire to encourage the growth of the human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, "Those things that hurt instruct." It is for this reason that wise people learn not to fear but to welcome the pain of problems.

    Samuel Morse was born in Massachusetts USA. He started off his career as an inventor after being a painter and sculptor (雕塑家). He even earned a gold medal from the famous Adelphi Society of Arts for his first effort in sculpture, the "Dying Hercules". He became the first president of the National Academy of Design, and was made Professor of the Arts of Design in the University of the City of New York.

    Yet, this painter turned to inventing to make his fortune during a sea voyage. On this journey, Samuel Morse heard about many attempts to create usable telegraphs. He was fascinated by this problem and began to study books on physics for two years to gain more scientific knowledge. He realized that pulses (脉冲) of electrical current could carry information over wires.

    Thus the world's first working model of a telegraph was born. His signaling device was quite simple. It consisted of a transmitter (containing a battery and a key), a small buzzer (蜂鸣器) as a receiver and a pair of wires connecting the two. Samuel Morse improved it by adding a switch and a second buzzer to allow transmission (传播) in the opposite direction as well.

    On May 24, 1844 Samuel Morse sent the first electronic message between Baltimore and Washington, "Look what God has enabled us to build, and benefit by."

    Seventeen years later, the two coasts of the United States were linked by telegraph. The telegraph continued to enjoy the position of being the fastest and most reliable means of communication for almost 140 years since its invention.

    People like to post their selfies(自拍照) on social media. To know more about it, scientists at Syracuse University in New York recently did a research and came up with some surprising findings.

    People who post selfies and use editing software to make themselves look better show behavior connected to narcissism(自恋), the researchers said. Makana Chock, a professor from Syracuse University, said because social media is mostly used by people to share unimportant information about their lives, it is a good place for people to "work towards satisfying their own vanity." Those "likes" under their Facebook selfies make them feel good.

    Besides, people who post group selfies show a need for popularity and a need to belong to a group, the research found. Some people feel "peer(同伴) pressure" to post selfies and some follow the popular belief that if there is no picture of an event or experience, it did not really happen. "Anyway, it shouldn't be seen as negative. People get sense of satisfaction especially when they get likes. And it does no harm," Chock said.

    Other findings from the study include: There are no major differences on how often men and women post selfies and how often they use editing software. But men who post selfies showed more of a need to be seen as popular than women who posted selfies.

Chock said posting selfies on social media is not all that different from what people have done for many years. On trips and special events, our parents and grandparents used cameras instead of phones to take photos. They would bring back photos to show friends and family. You had no choice but to look at them. You probably commented about how nice everyone in the photos looked, especially children and the person showing the photos. They were happy to hear your comments. That was the old way of "clicking like". On social media, however, people can decide not to look at photos — even if they click "like".
