I am a volunteer. I set out to help clean up the beach after a violent storm a year ago. The sight I saw was heartbreaking. The broken houses seemed to be crying. I couldn't describe how I felt. But something special among the debris (废墟) turned my day around.

    I joined a club to clean up the beach after the storm last November. As I removed the debris from the beach, I noticed an object with shiny buttons in the wet sand. It was a jacket，and I was excited since Halloween(万圣节) was coming and I thought I had found a great costume(戏服). After picking it up, I was able to see that the jacket was from West Point (西点军校), the United States Military Academy, and it had the name “deGavre” written inside. I realized the jacket might be important to someone. I decided to find the jacket's owner and return it.

    I called the West Point Museum, considering that if the family couldn't be found, the jacket should go there. The museum connected me with Kim McDermott, Director of Communications for the Academy's Association of Graduates. Kim soon ensured that the jacket had belonged to Chester Braddock deGavre, who was a 1933 graduate and a war hero, but passed away in 1993.

    I sent Kim a photo of the jacket and she posted it to the West Point Association of Graduates Facebook Page, asking if anyone could help us find the family. In less than two hours, someone had found and called the hero's wife, Teresa. Soon I started to receive personal messages from members of the deGavre family, their friends and others who were touched by the story and they found me on Facebook.

    Finding Chester deGavre's jacket and connecting to his family with the help of Facebook have been so meaningful to me. I've formed a bond(纽带) with amazing people I might have never met.

    A recent announcement by scientists that they have successfully cloned the first human embryo(胚胎) has caused much debate and has shocked many people around the world. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable tissues(组织) and organs that could be used to save human lives. On the other hand, many people, including some scientists, disagree and fear that if mankind interferes with (干涉) nature in this way, they may be on their way to producing a real-life Frankenstein's monster.

Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly—the sheep. She was born in 1996 and died in early 2003, at a much younger age than normal. When she was born, many people were angry because they thought cloning would create more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific breakthrough.

    The Scottish scientist who created Dolly, Ian Wilmut, is shocked that some scientists are now considering cloning human beings. Although he researches cloning, he has never thought of creating copies of humans. Instead, he thinks the scientists should concentrate on creating new tissues and organs that could eventually be used to cure diseases like cancer. However, some people consider that cloning human embryos with the intention of destroying them shows no respect for human lives.

    While cloning human embryos is illegal in many countries, some scientists are already pushing ahead with the research so as to deliver a cloned human baby. Severino Antinori, an Italian doctor, is one of the leaders in this field of research. He has declared that he wants to be the first to clone a human being.

In China, scientists have focused their efforts on cloning animals, as well as stem cells to be used in medical research. China has succeeded in producing clones of cows and goats, and continues to research ways in which cloning can benefit mankind.

    One morning, my newspaper wasn't delivered on time. Since I always brought it to work, it upset me that I would have to pick one up on my way to work. After breakfast, I was already running late, but figured I could make it if I hurried.

    As I pulled into the parking lot of the store, I noticed a young man in a wheelchair who seemed to be struggling. “Someone else will stop and help him,” I thought.

    However, no one stopped. I got out, and walked over to see what the trouble was.

    “Is there anything I can do?” I asked. It was then that I noticed he wasn't able to speak, and was still struggling with the chair.

    I looked down at the chair and noticed that the clamps (夹具) holding the electronic keyboard had apparently become loose causing the equipment to slip down, out of his reach.

    I pulled it back into place and then re-tightened the clamps. He hit a key on the keyboard. An electronic voice told me, “Thank you.” He then found the control that steered (操纵) the chair, turned and left.

    I got back in my car and headed off to work, completely forgetting my newspaper. As I drove, I felt a deep gratitude (感激). I was truly blessed to have the physical abilities that allow me to live a normal life. Here was this young man who relied on machines to get around and communicate. He probably dreamed about doing all the things that I thought were normal and simple.

    It's funny; fifteen minutes before that happened, I was whining because my morning paper hadn't arrived on time. I was glad I helped the young man, because he helped me gain a new viewpoint on everything I had in my life.

    Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there's no need for a lot of scientific terms or expensive lab equipment. You only have to share your children's curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we're finished with your lists, do you have questions of your own about science?”

    After a long pause, a boy raised his hand, “Have you ever seen a grasshopper （蚱蜢）eat? When I try eating leaves like that, I get a stomachache. Why?”

    This began a set of questions that lasted nearly two hours.

    Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical, complete and creative answers.

    Thirdly, watch your language. Once you have a child involved in a science discussion, don't jump in with “That's right” or “Very good”. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That's interesting” or “I'd never thought of it that way before”, or coming up with more questions or ideas.

    Never push a child to “Think”. It doesn't make sense, children are always thinking, without your telling them to. What's more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement.

    Lastly, show; don't tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass（放大镜）, and they'll understand why you want them to wash before dinner. Rather than saying that water evaporates（蒸发）, set a pot of water to boil and let them watch the water level drop.

    1) Steve Jobs, Stanford University:

    "Remembering you're going to die, and the best way I know is to avoid the trap of thinking that you have something to lose. There is no reason not to follow your heart. Your time is limited, so don't waste it living someone else's life. Don't let the noise of others' opinions drown out your own inner voice... "

    2) Oprah Winfrey, Stanford University:

    "I consider the world, this Earth, to be like a school... And the secret I've learned to get ahead is being open to the lessons from the grandest universe of all. Don't react against a bad situation. And the solution will arise from the challenge. So don't give up easily, acting with responsibility... "

    3) Bono, University of Pennsylvania:

    "For four years you've been buying, trading, and selling everything you've got in this market-place of ideas. Your pockets are full, even if your parents' are empty, and now you've got to figure out what to spend it on... The world is more flexible than you think and it's waiting for you to hammer it into shape... "

    4) Michael Dell, University of Texas at Austin:

    "Now it's time for you to move on to what's next and obtain your desire. But you must not let anything prevent you from taking those first steps. Don't spend so much time trying to choose the perfect opportunity, or sometimes you'll miss the right opportunity. Recognize that there will be failures and obstacles. But you will learn from your mistakes and the mistakes of others."
