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.

    We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(湿度)and nutrient availability seem to have trumped the benefits of increased carbon dioxide" said researchers from the National University of Singapore.

    45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures.

    " We do not yet know the mechanisms(机制)involved, or why some organism are getting smaller while others are unaffected," the researchers said. "Until we understand more, we could be risking negative consequences that we can't yet quantify."

    The change is big in cold-blooded animals. Only two decades of warmer temperatures are enough to make retiles (爬行动物)smaller. An increase of only 1 degree centigrade caused nearly a 10 percent increase in metabolism(新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growing.

    Warm-blooded animals aren't immune(免除)from the size change caused by climate change. Many birds are now smaller. Soay sheep are thinner. Red deer are weaken And polar bears are smaller, compared with historical records.

    This is not the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change.

    The speed of modem climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times climate change will be shown in the future.

    I had been in the city for some time and was coming home. I missed my boat and decided to travel on an old ship. I knew that it would not be a comfortable journey but I had no time to wait for another boat.

    Hardly had we left the port when I saw the dog Gulliver, the captain's favourite dog, for the first time. What a big dog it was! I had never seen one that could frighten me so much!

    On the third day the ship caught fire. Nobody tried to put it out. The ship began sinking and all the men rushed to the life-boats. I saw no chance of getting away in a boat. Suddenly I remembered there was a life-raft on the ship. I had no time to lose, so I immediately rushed towards the raft and pushed it overboard.

    In jumping down onto the raft I hurt myself badly and was unconscious for some time. When I came to, I found there was no sign of a life-boat. Every man who had been on board the ship must have gone down with her. I was the only one who was saved.

    Then I saw Gulliver was coming fast towards the raft. He struggled a long time before he managed to get onto it. I wanted to push him back into the water but did not dare to move. The dog shook himself, went to the other end of the raft and lay down. I didn't dare to sleep that night. I must watch him. In the moonlight I could see his eyes were open. He was watching, too.

    Making decisions when shopping is often tough. Even if you're satisfied with the first dress you try on, would you go on looking for alternatives, comparing styles and prices, until you drop dead?

    According to a recent Wall Street Journal column, psychology researchers have studied how people make decisions and concluded there are two basic styles.“Maximizers” are people who want the best. They like to take their time and weigh a wide range of options—sometimes every possible one—before choosing.“Satisfiers” would rather be fast than thorough. They are people who want to be good enough.

    Schwartz and his colleagues followed 548 job-seeking college seniors at 11 schools from October through their graduation in June. They found that the maximizers landed better jobs. Their starting salaries were, on average, 20 percent higher than those of the satisfiers, but they felt worse about their jobs.

    There is no right choice.“The maximizer is kicking himself because he can't examine every option and at some point had to just pick something,” Schwartz says.“Maximizers make good decisions and end up feeling bad about them. Satisfiers make good decisions and end up feeling good. ”

    Faced with so many choices in our lives, we need to learn how not to waste time and energy on our decision-making, says Jane C. Hu in Slate online magazine.Hu suggests, decrease your range of options. Once you've arrived at a decision, stick with it. Just accept that no decision is ever completely perfect, and remind yourself that it is the best you can do at the moment.

    Through your childhood and, let's be honest, most of your adult life, you may have wondered—how do you get to Sesame Street? After 50 years, the answer has finally been revealed.

    New York City's Official Sesame Street

    In the past, there was guessing about the true location of the street, like Harlem or Alphabet City since both neighborhoods resembled Sesame Street in appearance and population makeup. Recently, in honor of the children's television show's 50th anniversary, New York City Mayor Bill de Blasio declared that West 63rd Street between Central Park West and Broadway will now officially be known as Sesame Street, close to the Sesame Workshop office.

    A Year-long Celebration for the 50^th Anniversary

    Since 1969, the children's television show Sesame Street has been a pioneering force in media and education, dealing with issues like racism, loss, poverty and living with a disability. With a mission to help kids everywhere grow smarter, stronger, and kinder, Sesame Street has brought the life-changing benefits of early learning to children across the globe for 50 years. Today, we reach kids in 150 countries and 70 languages and we're celebrating our landmark anniversary with fans and families all year long!

    Events and Activities Throughout 2019

    Fans and families around the world can join their favorite furry friends in celebrating Sesame Street's past, present, and future, with:

    Birdbrain has long been a term when laughing at somebody. The common opinion is that birds' brains are simple. But that opinion has increasingly been called into question because crows and parrots, among other birds, have shown behaviors as smart as that of chimpanzees.

    The conflict of simple brain and complex behavior has led some neuroscientists (神经学家) to create a new map of the birdbrain.

    Today, in the journal Nature Neuroscience Reviews, an international group of bird experts is showing their opinion. Nearly everything written in anatomy (解剖学) textbooks about the brains of birds is wrong, they say. The bird brain is as complex, and creative as any mammal brain, they argue, and it's time to use a more exact term that shows a new understanding of the anatomies of bird and mammal brains.

    "Names have a powerful influence on the experiments we do and the way we think," said Dr. Erich, a neuroscientist at Duke University and a leader of the Bird Brain Terms Association. "Old term has prevented scientific progress."

    The association of 29 scientists from six countries met for seven years to develop new, more exact names for structures in both bird and mammal brains. For example, the bird's seat of intelligence or its higher brain is now named the pallium (大脑皮层).

    "The change of terms is a great advance," said Dr. Jon Kaas, a leading expert in neuroanatomy at Vanderbih University. "It's hard to get scientists to agree about anything."

    Scientists have come to agree that birds are indeed smart, but those who study bird intelligence differ on how birds got that way. Experts are split into two warring camps. One holds that birds' brains make the same kinds of internal (内在的) connections as do mammal brains and that intelligence in both groups arises from these connections. The other holds that bird intelligence developed through increasing an old part of the mammal brain and using it in new ways and it questions how developed that intelligence is.
