We were on the way from Hutchinson to Chicago for a short spring break. For many years I had wanted to take my family on the train. We all had been to Chicago four years ago, and the kids loved it. Chicago is one of my favorite cities, too, so the thought struck me again last fall to ride the train to Chicago. Of course, flying would have been faster. But I don't think flying is easier, especially these days, with all the security and waiting in lines at airports.

    Though we were tired in the middle of the night, the kids got on the train with the exhilaration of this adventure. “We're moving,” my son William shouted happily with big eyes as the train began to pull away from the Hutchinson station.

    I removed my shoes and lay down to try to finish my night's sleep. The sleeper car would have better enabled that, but the ordinary train seats were not too bad. An airline flight is a more miserable experience for me: not enough room, two hours of pain with my knees almost touching my chin, the hard seatback in front cracking my kneecaps (膝盖) with every move of the body planted in front of me. On the train I could almost outstretch all of my 6-foot-2-plus body in the generous legroom.

    The journey didn't feel at all as long as it was. We all found the train ride a joy. The car ride would have felt every minute of 13 hours. But on the train you are free to walk around, sit in the observation carriage for a while and enjoy the scenery out the windows, have a nice meal in the dining car, read a book, or play a board game.

    In short, the train is all about enjoying the trip, which isn't something I do so much when traveling by airline or by car, when the trip seems more of a mission (任务) to get there than an experience to enjoy along the way.

    Chicago offers much to do for a family. This time, getting there was half the fun.

    When other nine-year-old kids were playing games, she was working at a petrol station. When other teens were studying or going out, she struggled to find a place to sleep on the street. But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University. And her amazing story has inspired a movie, “ Homeless to Harvard: The Liz Murray Story”, shown in late April.

    Liz Murray，a 22-year-old American girl, has been writing a real-life story of willpower and determination. Liz grew up in the shadow of two drug-addicted parents. There was never enough food or warm clothes in the house. Liz was the only member who had a job. Her mother had AIDS and died when Liz was just 15 years old. The effect of that loss became a turning point in her life. Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.

    Liz went back to school. She threw herself into her studies, never telling her teachers that she was homeless. At night, she lived on the streets. “ What drove me to live on had something to do with understanding, by understanding that there was a whole other way of being. I had only experienced a small part of the society,” she wrote in her book Breaking Night.

    She admitted that she used envy to drive herself on. She used the benefits that come easily to others such as a safe living environment, to encourage herself  that “next to nothing could hold me down”. She finished high school in just two years and won a full scholarship to study at Harvard University. But Liz decided to leave her top university a couple of months earlier this year in order to take care of her father, who has also developed AIDS. “I love my parents so much. They are drug addicts. But I never forget that they loved me all the time.”

    Liz wants moviegoers to come away with the idea that changing your life is “as simple as making a decision”.

    Bamboo is one of the world's most useful plants. For thousands of years, bamboo has been used in many different ways-from food to medicine to clothing and, in small ways, as a building material.

    However, bamboo is not often used as a building material in the developed world. A professor at the University of Pittsburgh in Pennsylvania is trying to change that. The professor and his students are testing the strength of bamboo.They are testing how much pressure or weight it can take before breaking.

    Kent Harries is a professor at the University of Pittsburgh. Harries says that testing methods for bamboo need to be the same for all. They need to be standardized. Standardizing test methods for bamboo will help to bring the plant into common use. It will also give engineers and builders around the world a dependable standard.

    Harries says that bamboo is strong in nature. The strength of at least three species of bamboo is similar to steel.Besides its strength, bamboo has other features that make it very useful in building. He says it is resilient(有弹力的), meaning it keeps its shape and strength even under pressure.

    Bamboo also grows quickly. Bamboo that is suitable for construction needs much less resources than wood. The harvest cycle of bamboo is about 3 years. Softwoods such as cedar, pine and spruce have a harvest cycle of about 10 years. And hardwoods that come from flowering plants such as oak and walnut need more than 30 years.

    Bamboo is widely used as food for panda bears. It is also used for flooring and window covers. However, for building, bamboo is not used much outside its native growing area. This is mostly because of its round shape. But there are other reasons too. People think -- or have the mentality--that bamboo is a low quality building material.

    There is a lot to learn about the creations of Beatrix Potter — not only is she the author and illustrator of one of the world's most famous children's books, The Tale of Peter Rabbit, but also a pioneering conservationist with the spirit of a scientist.

    "Potter grew up as the daughter of a wealthy Victorian family, but along with her brother who filled an entire floor of their large house in London with all sorts of animals," said Anne Lundin, a retired professor for the UW-Madison School of Library and Information Studies.

    "As an adult, she was a frustrated botanical illustrator and scientist. That field was not open to her because she was female," Lundin said. Potter was urged to turn the charming illustrations and stories she wrote in letters to children into books. She wrote 23 books in all — a body of work that has inspired plays, ballets, films and an astonishing amount of merchandise.

    "The Tale of Peter Rabbit is probably the most famous children's book in the world, which was published in 1902 and has really stood the test of time. It's been translated into 36 languages. The parents and grandparents will share it with the next generation," said Lundin.

    Potter also made a mark on the world through her land conservation. "In many ways, she was like Peter Rabbit, venturing into a world of adventure and risk. She withdrew from London as soon as she started making some money on her books to the Lake District and became an extremely important farmer and conservationist. She preserved and passed on 15 farms and over 4,000 acres, which were given back to the country as gifts in the 20th century," said Lundin.

    Even though she was born 150 years ago, she was amazingly modern — her embracing of the natural world, commented Jennifer Blatchley Smith, an artistic director of the show Peter Rabbit Tales to celebrate the 150th anniversary of Potter's birth.

    In today's society, language plays a key role in defining gender (性别) by vocabulary, and also their non-verbal (非语言的) vocabulary. Each one of these different types of ways of communicating is obviously different between men and women.

    Many different studies show that men tend to talk much more than women. It has also been proven that women tend to speak faster than men; this is due to the fact that women tend to be interrupted more often than men are, and also have the ability to speak more clearly, precisely, and more quickly than men. In one study it was found that women spoke for an average of three minutes describing a painting, as opposed to the thirteen-minute average it took men to describe it.

    Men and women also tend to have a very different non-verbal way of communicating, which can also make it very hard for one another to understand what the opposite sex is trying to say. Men's body language is much more reserved when talking to women. Men tend not to make as much eye contact and they generally stay farther away from women when talking to them. Men avoid other people's body space while talking, and they also tend to sit back when talking. All of these have given off the impression of disinterest or boredom. Women are by far better listeners and much more enjoyable to talk with and they tend to raise more topics for conversation.

    Women also make it clearer whether or not the conversation is going somewhere or just stuck in neutral. After learning about our styles of communicating with each other, I have decided that although men have not quite mastered communicating, what fun would it be if we all spoke the same "language"? The little games men and women play with each other while conversing would be lost. The question everyone asks himself or herself after talking with someone of the opposite sex, "I wonder if there's something there?" would no longer exist.

    Cao Zhawa has been planting trees for most of his life. He lives and works in the heart of Mu Us Sandyland, an area in the southwest part of Inner Mongolia.

    In 1958, when he was just 16 years old, Cao started planting trees. Cao's trees now cover an area of more than 1.3 million square meters. Cao's forest is worth an estimated 10 million yuan and can produce 100,000 kilograms oxygen, enough to sustain a full-grown adult for nearly a year.

    Mu Us Sandyland is one of the places in China most affected by erosion(侵蚀) and desertification. The amount of annual rainfall ranges from 150 to 300 millimeters, while evaporation(蒸发) between 2,000 and 3,000 millimeters. Cao recalls that his growing-up was troubled by sandstorms. This was one of the factors that motivated Cao to join and stay on the tree-planting program.

    Popularly known as the "Green Great Wall", the project, which is set for completion in 2050, would be a 4, 800-kilometer greenbelt of trees and shrubs(灌木) protecting the area from strong winds and preventing soil erosion. Since the start of the Three-North Shelter Forest Program, millions of people have joined in and become a vital part of the plan.

    However, the tree-planters face a host of challenges, with watering the most difficult among them. "When I was young, the level of groundwater was high," said Cao, "But with less rain, the trees are hard to plant and keep alive."

    Planting trees has also become harder for Cao as he ages. However, he doesn't want to leave the forest in the care of his children, and he insists the land belongs to the government. "When I die, I just want to be buried under the trees," Cao said. "Then I will be with them forever."
