Imagination Stage is a children's theater in the state of Maryland. A special performance is put on for children with autism (自闭症) each day. People with autism have difficulty communcating and socializing with other people. Children in the theater are allowed to move around during the performance. It's OK if they shout out or hold their ears when the music is too loud. These special performances are sometimes the only thing that a family can go to the theater together to see if a child has autism.

    That is the same idea with Autism on the Seas. This company organizes vacations for families of children with autism, especially vacations on cruise ships. Jamie Grover is director of group development in Autism on the Seas. He said, “With our staff on board, parents know that they are going to be able to relax, enjoy their vacation, and participate in ship activities. They know that their children are well taken care of.”

    The benefit of such vacations organized by Autism on the Seas is not waiting in huge lines on departure day. The company has staff to help in the ports. Waiting in long lines or being in the middle of big crowds can cause problem behavior in children with autism. Autism on the Seas helps families avoid situations like that.

    Autism on the Seas works with the help of cruise companies like Royal Caribbean. Special times or places are arranged for families to play video games, go skating or rock climbing, or eat dinner. Autism on the Seas also directs families to organizations that can help them pay for these vacations.

    Bambi Van Woert from the state of Michigan went on a cruise with her 7-year-old Ben, who has autism. She said, “I would never do something like this myself. I cannot take Ben shopping by myself at this point, so for me to try to do a cruise without help would be absurd.”

    Mirroring China's Past: Emperors and Their Bronzes

    Chinese bronzes (青铜) of the second and first millennia BC are some of the most distinctive achievements in the history of art. These vessels (容器) were made to carry sacrificial offerings, to use in burial or to honor noble families in public ceremonies. When they were found by emperors centuries later, these spiritually significant objects were seen as signs of heavenly messages about a ruler or a dynasty and became prized items in royal collections. This exhibition —the first to explore these ancient objects throughout Chinese history — presents a rare opportunity to experience a large number of these works together in the United States.

    Unlike Greek and Roman bronze sculptures of human and animal forms, most objects from Bronze Age China (about 2000 - 221 BC) were vessels for ceremonial use. Beginning with the Song dynasty (960 - 1279), emperors unearthed these symbolic works and began collecting them, considering them to be evidence of their own authority as rulers. In addition to impressive collections, the royal fascination with bronzes led to the creation of numerous reproductions and the comprehensive cataloguing of palace holdings. These catalogues are works of art themselves, featuring beautiful drawings and detailed descriptions of each object.

    From the 12th century onward, scholars and artists also engaged in collecting and understanding ancient bronzes. Unlike emperors, scholars regarded bronzes as material evidence of their efforts to recover and reconstruct the past, and they occasionally exchanged them as tokens (象征) of friendship. Today ancient bronzes still occupy a primary position in Chinese culture — as historical objects and as signifiers of an important cultural heritage that inspires new generations, as seen in the works of contemporary artists on view in this presentation.

    Mirroring China's Past brings together approximately 180 works from the An Institute of Chicago's strong holdings and from the Palace Museum in Beijing, the Shanghai Museum, and important museums and private collections in the United States. By providing viewers with a new understanding of ancient bronzes and their significance through time, the exhibition demonstrates China's fascinating history and its developing present.

    In Europe many people died during the Second World War. As a result, at the end of the war there were many orphans (孤儿) there. A man called Hermann Gmeiner wanted to help these children. His idea was simple. He wanted orphans to have a home, and he wanted them to have the care and kindness of parents. Gmeiner asked people to give him some money. With this money he built the first SOS Children's Village at Imst, in Austria. It opened in1949. This is how the SOS stand for “Save Our Souls（灵魂）.” This means, “Please help us!” An SOS Children' village gives help to orphans. Hermann Gmeiner's idea for helping orphans soon spread（传播）all over the world. By 1983 there were 170 SOS Children's Villages in the world. People in many countries give money to help the villages.

    Today the children from the first village have grown up. Now some of them work in other SOS Children's Villages. In SOS Villages orphans live in family groups. There are several houses in each village. The biggest village has 40 or 50 houses! Between seven and ten children live in a house. A woman lives with each group of children and looks after them. She gives the children a lot of love and kindness. She cooks meals for them and makes comfortable, happy home for them.

    Of course, the children don't spend all their time in the village. They go to school; they go out with their friends. But the village gives them a home—sometimes for the first time in their lives.

    You can see a sea turtle named Herman, an octopus ( 章鱼) called Octavia, and a seal named Lidia at the Smithsonian's National Zoo in Washington, D.C. Rather than real animals, they are actually artworks made out of plastic trash from the ocean.

    These artworks are part of a traveling exhibit called "Washed Ashore: Art to Save the Sea". The Washed Ashore project, led by the artist called Pozzi, works to raise awareness about plastic pollution in Earth's oceans.

    More than 315 billion pounds of plastic litter the world's oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches. Rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces.

    Thousands of sea animals die each year from eating plastic bags and other things. Each year, millions more pounds of plastic end up in the ocean. A recent study found that if that continues, by 2050 the total weight of plastic will be more than that of all the fish in the ocean.

    The Washed Ashore project is working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38,000 pounds of plastic trash from more than 300 miles of beaches. They helped Pozzi create more than 60 artworks of sea creatures harmed by plastic pollution.

    "These artworks are a powerful reminder of our personal role and global responsibility in preserving biodiversity (生物多样性) on land and in the sea," says Dennis Kelly, director of the National Zoo.

    Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play, catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, extra learning trials (尝试) increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables (乘法口诀表) are an exception (例外) to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

The law of overlearning explains why cramming (突击学习) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.

    You have just won ten million yuan in a lottery (彩票) - how would you spend it? Before you know it, ten minutes had gone on daydreaming. There is a time and a place for daydreaming, but we don't have much control over that. Isn't it worrying that an estimated 30 to 50 percent of our waking time is spent daydreaming? What if your dentist is having that lottery daydream while removing your rotten tooth?

    Some studies suggest daydreaming makes us unhappy because we are not focusing on what is around us but are instead thinking about the past or future. However, a recent study published in the journal Neuropsychologica finds that mind-wandering can be of benefit to us. The researchers measured the brain patterns of more than 100 people using an MRI (核磁共振成像) scanner. This data was compared with tests on creative ability and a questionnaire on how much their minds usually wandered. Those whose minds wandered the most scored higher in creative ability tests and had more efficient brain systems measured in the MRI machine.

    Being efficient at mind-wandering means you can zone out and then naturally switch back in without missing any important point or step. Christine Godwin, the lead author of the latest study from the Georgia Institute of Technology, says that if you are focusing on difficult tasks, your performance will drop if your mind wanders. “But when tasks are easy, people who have high cognitive ability can let their minds wander because it does not affect their performance. You may be thinking about upcoming goals or problem-solving. These are some of the positive sides to mind-wandering."

    Mind-wandering can vary between being more practical or more emotional. What mind-wandering seems to be best at, researchers say, is coming up with new solutions to old problems. So, it's not always a waste of time!
