When I was about 12, I had an enemy, a girl who liked to point out my shortcomings (缺点). Wee k by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.

    He listened to me quietly, then he asked. “Are the things she says true or not? Janet, didn't you ever wonder what you're really like ? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”

    I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I went to a fairly clear picture of myself.

    I brought the list back to Daddy. He refused to take it. “That's just for you,” he said. “You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”

    Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice.

    Harvard researchers have created a tough, low-cost, biodegradable (可生物降解的) material inspired by insects' hard outer shells. The material's inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative to plastic. The material, made from shrimp ('虾) shells and proteins produced from silk, is called "shrilk." It is thin, clear, flexible and strong.

    A major benefit of the material is its biodegradability. Plastic's toughness and flexibility represented a revolution in materials science during the 1950s and '60s. Decades later, however, plastic's very durability (耐用性) is raising questions about how appropriate it is for one-time products such as plastic bags, or short-lived consumer goods, used in the home for a few years and then cast into a landfill where they will degrade for centuries. What is the point of making something that lasts 1,000 years?

    Shrilk not only will degrade in a landfill, but its basic components are used as fertilizer(肥料), and so will enrich the soil.

    Shrilk has great potential, the inventors said. Materials from which it is made are plentiful in nature, found in everything ranging from shrimp shells, insect bodies to living plants. That makes shrilk low cost, and its mass production possible should it be used for products demanding a lot of material.

Work on shrilk is continuing in the lab. The inventors said the material becomes flexible when wet, so they're exploring ways to use it in wet environments. They're also developing simpler production processes, which could be used for non-medical products, like for computer cases and other products inside the home. They're even exploring combining it with other materials, like carbon fibers, to give it new properties.

    Street art is a very popular form of art that is spreading quickly all over the world. You can find it on building, sidewalks, street sings and trash cans from Tokyo to Paris, and from Moscow to Cape Town. Street art has become a global culture and even art museums and galleries are collecting the works of street artists. Even advertising companies also use street art in their ads due to its popularity.

    Street art started out very secretly because it's illegal to paint on public and private property without permission. People often have different opinions about street art. Some people think it is a crime with others think it's a new form of culture.

    Art experts claim that the movement began in New York in the 1960s. Young adults sprayed words and images on walls and trains. This colorful and energetic style of writing became known as graffiti(涂鸦). Graffiti art showed that young people wanted to rebel against society. They didn't want to accept rules, and they travelled around cities to create paintings that everyone could see. In many cases, they had trouble with the police and the local government.

    Many street corners in Paris show the works of Space Invader. A French artist uses small pieces of glass to make images of space creatures. He has been doing this for some years and the police have arrested him a few times. On his website, you can see many other places where he has created this form of art.

    Street artists do their work for some reasons. Some of them do not like the artists who make so much money in galleries and museums. They choose street art because it is closer to common people. Some artists try to express their political opinion in their works. They often want to protest against big firms and corporations. Others like to do things that are forbidden and hope they don't get caught.

    In today's world, the Internet has a big influence on street art. Artists can show their pictures to people all over the world. Many city residents, however, say that seeing a picture on the Internet is never as good as seeing it alive. The street art movement lives with the energy and life of a big city. There it will continue to change and grow.

    What's the meaning of "dark horse"? It's someone who wins when no one expects it.Han Xiaopeng took China's first gold on snow. He became an Olympic "dark horse" by winning the gold medal in men's freestyle aerial skiing(自由式滑雪空中技巧) at Turin in Italy. He made two almost perfect jumps for the highest score. Han had never won a world gold medal before, let alone(更不用说) in the Olympics!

    "I never thought this would happen," said the 23-year-old. "I feel like I'm in a dream." It's China's second gold medal at the Turin Olympics. But more important, Han's gold was the country's first ever in a snow sport. In 2002, China's Yang Yang won the gold for speed skating at the winter Olympics in Salt Lake City, US.

    That Han's win was unexpected doesn't mean that he didn't work hard.

    Han grew up in Jiangsu Province. Before he started his training on snow, he used to be an acrobat(杂技演员) at a circus. In 1995, a coach found his talent(才能). The coach, Yang Er'qi, said Han had the agility(灵活性) and courage to be a ski jumper. When Yang first took the 12-year-old to northern China, the boy couldn't swim, skate or ski. But he wasn't afraid of the high platform(跳台) and kept on training.

    Han almost left the sport after hurting his knee months before the Salt Lake Games. In that Olympics he only got 24th. "I was hopeless at that time, but my family and the coach stood firmly(坚强地) behind me, helping me through," he recalled.

    Han Xiaopeng worked so hard that he won the gold medal in the Olympics at last. Because of his success, more and more people in China are becoming interested in skiing. We are proud of him and we hope he will have another big success in the next winter Olympics.

    Being forgiving to yourself and others can protect against stress and the harm it does to mental health, according to a new study in the Journal of Health Psychology.

    Researchers looked at the effects of lifetime stress on a person's mental health, and how more forgiving people got along compared with people who weren't so forgiving. To do this, they asked 148 young adults to fill out questionnaires that assessed their levels of lifetime stress, their tendency to forgive and their mental and physical health.

    No surprise, people with greater exposure to stress had worse mental and physical health. But the researchers also discovered that if people were highly forgiving of both themselves and others, that characteristic alone almost removed the connection between stress and mental illness.

    "It's almost entirely erased—it's zero," says study author Toussaint. "If you don't have forgiving tendencies, you feel the immediate effects of stress in a severe way. You don't have anything to cushion you against that stress."

    How a forgiving personality protects a person from the influence of severe stress is hard to determine. The researchers infer that people who are more forgiving may adopt better skills to deal with stress, or their reaction to major stressors(压力源)may be slow.

    Though more research is needed to fully understand the benefits of being more forgiving, Toussaint believes"100％"that forgiveness can be learned. His own previous research has shown that saying a short prayer on forgiveness can help people take the edge off. "I think most people want to feel good and forgiveness offers you the opportunity to do that," he says.
