Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets(彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash(垃圾) there that scientists are now concerned that if we don't clean it up, we may all be in mortal(致命的) danger.

    The first piece of space junk was created in 1964, when the American satellite Vanguard Ⅰ stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning(抛弃) things that no longer served any useful purpose in space.

    It is estimated(估计) that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.

    The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft(飞船). Moreover, pieces of junk may collide(碰撞) with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.

    As a young girl growing up in the 1930s, I always wanted to fly a plane, but back then it was almost unheard of for a woman to do that. I got a taste of that dream in 2001, when my husband arranged for me to ride in a hot air balloon for my birthday. But the experience turned out to be very dull. Around that time, I told my husband that I wanted to skydive. So when our retirement community announced that they were having an essay competition and the topic was an experience of a lifetime that you wanted to have, I decided to write about my dream.

    In the essay, I wrote about my desire to skydive, stating George Brush Sr. did age 80. Why not me? I was just 84 and in pretty good health. A year went by and I heard nothing. But then at a community party in late April 2009, they announced that l was one of the winners. I just couldn't believe it. Inspired by this, I decided to realize my dream, even though some of my family members and my doctor were against it.

    One June 11, 2009, nearly 40 of my family and friends gathered in the area close to where I would land while I headed up in the airplane. My instructor, Jay, guided me through the experience. The plane was the noisiest one I had ever been in, but I wasn't frightened－I was really just looking forward to the experience. When we reached 13,000 feet, Jay instructed me to throw myself out of the plane. When we first hit the air, the wind was so strong that I could hardly breathe. For a second I thought, “What have I gotten myself into?” But then everything got calmer. We were in a free fall for about a minute before Jay opened the parachute （降落伞）, then we just floated downward for about five minutes. Being up in the clouds and looking at the view below was unlike anything I have ever felt－much better than the hot air balloon. I was just enjoying it.

    Skydiving was really one of the greatest experiences of my life. I hope other people will look at me and realize that you don't stop living just because you are 84 years old. If there's something you want to experience, look into it. If it's something that is possible, make it happen.

    The National Storytelling Youth Olympics is an event where thousands of kids from grades 6 to 12 compete against each other by telling stories. It is sponsored by the Master's Degree Program in Reading and Storytelling at East Tennessee State University. The sole purpose of this event is to promote and encourage both the art and science of storytelling among middle school and high school students. Although this event is competitive, its underlying intent and goal is to provide students across the nation with a reason to practice numerous noncompetitive skills.

    Those skills include skillful sportsmanship , responsible behavior, and an attitude of respect for others and the storytelling genre. The eventual goal of the National Storytelling Youth Olympics is to encourage every classroom in America to discover (or rediscover) the beauty of storytelling and story performance.

    The National Storytelling Youth Olympics takes place usually around the first weekend in March. Students from all over the country arrive by bus, plane, or automobile in Johnson City, Tennessee. They usually arrive on Thursday or Friday. Those that arrive on Thursday take advantage of their early arrival by telling stories at local schools. On Friday, an evening meal is prepared for all contestants, coaches, and parents. Games are played, stories are told, and lifetime friendships begin. Saturday is the day of the big event. A luncheon(午餐会) is held in the afternoon so contestants can familiarize themselves with the surroundings and do a sound check.

    The event is divided into three categories separated by grades. Contestants are judged not only by their storytelling performance, but also by the attitude and behavior they display during the entire weekend. A winner is picked from each of the three categories; however, there is an overall winner who is granted the name of Grand Torch Bearer. This person is selected not only by the judges, but also by the contestants. After the winners have been announced, the contestants retreat back to their hotel where a celebratory ice cream party is held; and believe it or not, they tell more stories! This is what the National Storytelling Youth Olympics is all about: developing a love for the art of storytelling.

    Skeptics are a strange lot. Some of them refuse to admit the serious threat of human activities to the environment, and they are tired of people who disagree with them. Those people, say skeptics, spread nothing but bad news about the environment. The "eco-guilt" brought on by the discouraging news about our planet gives rise to the popularity of skeptics as people search for more comforting worldviews.

    Perhaps that explain why a new book by Bjorn Lomborg received so much publicity. That book, The Skeptical Environmentalist, declares that it measures the "real state of the world" as fine. Of course, another explanation is the deep pockets some big businesses with special interests. Indeed, Mr. Lomborg's views are similar to those of some Industry-funded organizations, which start huge activities though the media to confuse the public about issues like global warming.

    So it was strange to see Mr. Lomborg's book go largely unchallenged in the media though his beliefs were contrary to most scientific opinions. One national newspaper in Canada ran a number of articles and reviews full of words of praise, even with the conclusion that "After Lomborg, the environmental movement will begin to die down."

    Such one-sided views should have immediately been challenged. But only a different review appeared in Nature, a respected science magazine with specific readership. The review remarked that Mr. Lomborg's "preference for unexamined materials is incredible (不可信的)".

    A critical (批判的) eye is valuable, and the media should present information in such a way that could allow people to make informed decisions. Unfortunately, that is often inaccessible as blocked by the desire to be shocking or to defend some special interests. People might become half-blind before a world partially exhibited by the media. That's a shame, because matters concerning the health of the planet are far too important to be treated lightly.

    Put an ice cube(小冰块) from your fridge into a glass of water. You have a piece of string(线) 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers (手指).

    You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.

    First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt(融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze(冻结) again.

    After a minute or two you may raise(提起) the piece of string and with it you will raise your piece of ice!

    This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don't put enough salt, the water will freeze again.
