Hello. I'm Jan from Mrs. Lake's class. My class wants to work together to help the public. We think we have found a great way to do this. Last month we did a class project on the highways near our town. We learned about the Adopt-a-Highway Program. This program brings people together to pick up litter along the roads. We think it would be a great idea for all students in our school to join the program and adopt（收养） a highway.

    Adopting a highway is not like adopting a pet. When a highway is adopted, only part of the highway is cared for by a group of people. The group agrees to work every week to keep its part of the highway clean. Each group gets its own sign that has the name of the group printed on it. The sign is put up at the side of the road. This sign lets drivers know who is keeping that area of the road clean.

    The Adopt-a-Highway Program is a great way for people to help their environment look nicer. Also, the government does not have to send out as many road workers. This saves money. Finally, people may try harder to keep roads clean if they see people, especially teenagers like us, cleaning them up.

    We will need helpers to care for our adopted highway. If you want to feel great and keep our roads clean，please come with your parents to the meeting next week. We will meet in Mrs. Lake's room on Wednesday at 6:00 P.M. At the meeting, we will talk about which roads are the dirtiest as a result of people's unkind acts. Then we'll try to pick an area to adopt and clean.

    I look forward to seeing you at the meeting. Remember to keep our roads clean!

    Festivals play an important role in a culture's identity. I can't think of a better way of appreciating a new culture than by taking part in one of its festivals. Here are some special festivals around the world．

    Boryeong Mud Festival－Boryeong, South Korea

    For two weeks in July, millions gather in Borueong to experience the grey pools and slides．What began as a way of promoting the region's mineral-rich mud has turned into a festive party, complete with music and fireworks.While the mud is usually only available in cosmetic products, here you can cake yourself in grey as you want．

    Holi－India

    Holi, the Festival of Colors, is a Hindu celebration full of joy and one of India's most important holidays. During the day of the last full moon of the lunar month, usually late February throughout the country, but the cheerful spirit is common throughout Hindu communities around the world．

    Koninginnedag－The Netherlands

    Although their current Queen's birthday is really during the winter, the Queen still celebrates it on April 30th, the country's official “ Queen's Day” since 1949．Orange is the national color, and the streets become a sea of feather boas（长围巾）and body paint as crowds gather in the plazas（广场）．Amsterdam is the center of this outdoor party, with many live music acts, but nearly every town is alive with orange on this day．

    National Elephant Day in Thailand

    In Thailand, March 13th is regarded as National Elephant Day to show that the Thai elephant plays an important role in the Thai history. Thai Elephant Day has been held on an annual basis since the idea was first approved by the Thai government in 1998. Special events are held at a number of venues in northern Thailand．At the Mae Sa Elephant Camp, it has become a tradition on March13th for the dozens of elephants there to be treated to a huge feast of fruits and sugarcane．

    Play allows children to use their creativity while developing their imagination and physical, cognitive（认知的）, and emotional strength. Play is important to healthy brain development. Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles. Undirected play allows children to learn how to work in groups, to share, to negotiate, and to resolve conflicts.

    Ideally, much of play involves adults, but when play is controlled by adults, children acquiesce（顺从）to adult rules and concerns and lose some of the benefits play offers them, particularly in developing creativity, leadership, and group skills. In contrast to passive entertainment, play builds active, healthy bodies. In fact, it has been suggested that encouraging unstructured play may be an exceptional way to increase physical activity levels in children, which is one important strategy in the resolution of the obesity problem.

    Children's development is critically influenced by appropriate, affective relationships with loving and consistent caregivers as they relate to children through play. When parents observe their children in play or join with them in child-driven play, they are given a unique opportunity to see the world from their children's vantage point as the child navigates a world perfectly created just to fit his or her needs. The interactions that occur through play tell children that parents are fully paying attention to them and help to build enduring relationships. Parents who have the opportunity to look at their children's world learn to communicate more effectively with their children aid are given another setting to offer guidance. Less verbal children may be able to express their views, giving their parents an opportunity to gain a fuller understanding of their perspective. Quite simply, play offers parents a wonderful opportunity to engage fully with their children.

    Play is essential to the academic environment. It ensures that the school setting attends to the social and emotional development of children as well as their cognitive development. It has been shown to help children adjust to the school setting and even to strengthen children's learning willingness. Social-emotional learning is best integrated（融合）with academic learning; it is concerning if some of the forces that enhance children's ability to learn are improved at the expense of others. Play and unscheduled time that allow for peer interactions are important components of social-emotional learning.

    One afternoon I toured an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet view of the art works.

    A young couple viewing the paintings ahead of me chatted nonstop between themselves. I watched them a moment and decided the wife was doing all the talking. I admired his patience for putting up with her continuous talk. Distracted by their noise, I moved on.

    I met with them several times as I moved through the different rooms of art. Each time I heard her constant burst of words, I moved away quickly.

    I was standing at the counter of the museum gift shop making a purchase when the couple came near to the exit. Before they left, the man reached into his pocket and pulled out a white object. He extended it into a long stick and then tapped his way into the coatroom to get his wife's jacket.

    “He's a brave man.,” the clerk at the counter said, “Most of us would give up if we were blinded at such a young age. During his recovery, he made a promise that his life wouldn't change. So, as before, he and his wife come in whenever there's a new art show."

    “But what does he get out of the art?” I asked. “He can't see.”

    “Can't see? You're wrong. He sees a lot. More than you or I do,” the clerk said. “His wife describes each painting so he can see it in his head.”

    I learned something about patience, courage and love that day. I saw the patience of a young wife describing paintings to a person without sight and the courage of a husband who would not allow blindness to change his life. And I saw the love shared by two people as I watched this couple walk away.

A living robot has been created out of frog skin cells. Xenobots, named after the frog species Xenopus laevis that the cells come from, were first described last year. Now the team behind the robots has improved their design and demonstrated new capabilities.

To create the xenobots, Michael Levin at Tufts University in Massachusetts and his colleagues obtained tissue from 24-hour-old frog embryos after very small physical operation. Where the previous version relied on the contraction of heart muscle cells to move them forward by pushing off surfaces, these new xenobots swim around faster. They also live between three and seven days longer than their previous generation, which only lasted about seven days, and have the ability to sense their surroundings to some extent, turning red when exposed to blue light.

"The fundamental finding here is that when you free skin cells from their normal context, and you give them a chance to build other things than what they normally build," says Levin. "To me, one of the most exciting things here is that they are plastic. This idea that even normal cells, not genetically modified, are in fact capable of building something completely different."

Because they are created from cells, the xenobots eventually break apart and are totally biodegradable, says team member Douglas Blackiston, also at Tufts University. He therefore hopes that they can be used for biomedical and environmental applications.

Previous attempts at creating living robots, such as a wirelessly controlled cockroach, have involved dealing with live animals, raising ethical concerns. Xenobots differ from these because they are made entirely of living cells. "The approach here is maybe ethically the least problematic because everything starts with cells. They have no neurons, so it's not an animal," says Auke ljspeert at the Swiss Federal Institute of Technology at Lausanne, who wasn't involved in the research. "It's really cells, so I find it maybe the cleanest way."
