Welcome to our school. You can do a lot of things here. Come and join us.

    There is an old saying about volunteer work that goes like this: “ No one can do everything, but everyone can do something.”

    Today, many people volunteer their time and energy to help others. There are a lot of ways to meet other people's needs. For example, some volunteers provide help after a disaster. Others are happy to get dirty while repairing homes or planting trees or flowers in poor neighborhoods. Young people see suffering and loneliness around them and find ways to help. And history lovers help archeologists(考古学家) search for ancient objects to help deepen our knowledge of the past.

    Volunteers work in many areas around the world, including Haiti. More than four years have passed since a 7.0 earthquake shook the nation. The exact number of people who died may never be known. Thousands of survivors of the Haitian earthquakes still live in temporary shelters. Last year, former American President Jimmy Carter and his wife Rosalynn joined five hundred volunteers in the town of Leogane to build houses.

    Organizations do not have to be large to get volunteers. An activist group in Dharamsala, India is a good example, Jodie Underhill from England arrived in northern India several years ago. She planned to volunteer for an environmental project. She could almost not believe how much rubbish was ruining some of the area's most beautiful sights. Jodie Underhill learned about how to deal with the rubbish while taking part in other volunteer projects. But soon enough she formed her own group, Mountain Cleaners. Jodie Underhill says the work is very hard. But she praises the group's efforts as a wonderful experience. The young Englishwoman says the Indian media started calling her “Garbage Girl”. And she says she was pleased with the name.

    American teenagers also volunteer in many ways .

    Last week, my granddaughter started kindergarten, and I wished her every success. But part of me didn't. I actually wanted her to fail in some ways because I believe that failure can be good for our learning process. Success is proving that you can do something that you already know you can do, or doing something correctly the first time, which can often be a problematic victory. First-time success is usually a luck. First-time failure, however, is supposed to be the natural order of things. Failure is how we learn.

    In Africa they describe a good cook as “she who has broken many pots”. If you've spent enough time in the kitchen to have broken a lot of pots, probably you know a fair amount about cooking. I once had dinner with a group of cooks, and they spent time comparing knife wounds and bum scars. They knew how much their failures gave them.

    I earn my living by writing a daily newspaper column. Each week I know that one column I write is going to be the worst column. I try my best every day. I have learned to love that column. A successful column usually means that I am discussing my familiar topic, writing in a style I am used to or saying the same things as anyone else but in a better way.

    My younger daughter is a trapeze artist（荡秋千演员）. She spent three years practicing a show, and she did it successfully for years. There was no reason for her to change it but she did anyway. She said she was no longer learning anything new and she was bored. She risked failure and great public embarrassment in order to feed her soul.

    My granddaughter is a perfectionist. She will feel her failures, and I will want to comfort her. But I will also, I hope, remind her of what she learned, and how she can do better next time.

    Nowadays science has made great progress in every aspect and more and more really good inventions have changed our daily lives. However, the U.S. Patent Office has issued over 7.5 million patents (专利), and not all of them are quite so celebrated. Some good, some bad, and some crazy! The following lists some of the most unusual ideas that have come along.

    Snake Leash (皮带)

    In 2002, a patent was issued for a snake-walking leash. There are at least two major problems with this idea. 1) Dog leashes fit securely between the head and shoulders. A snake does not have shoulders; so it might slither (蜿蜒滑行) away. 2) Dogs are OK for public places because they are social animals, and people like them. Snakes are not OK for public places because they are not social, and some people are terrified of them.

    Stadium Helmet

    Americans are known for their love of sports. Unfortunately, good tickets to games are expensive, so some fans have to sit in the backward sections. This invention, patented in 2000, is designed for these fans. Featuring a built-in radio, binoculars (望远镜), a cooling fan, and a helmet for falling litter, this design transforms the stadium experience.

    Bacon Alarm Clock

    When you think about it, waking to the dreadful, blaring noise of an alarm clock is a terrible way to start the day. However, this clock could change that. You simply put a piece of frozen bacon in the alarm clock, set the alarm, and go to sleep. The clock gently wakes you up with the mouth watering smell of bacon the next morning, just like waking up on a Sunday morning to the smell of mom cooking breakfast. Who said there's no time to eat breakfast?

    Toilet Lock

    In 1969, a patent was issued for a really bad idea the toilet seat lock. First of all, fishing for your keys when you have to go seems very unpleasant. Then there is the possibility of losing the key altogether. What about guests? Just think that you would have to ask permission for the bathroom. Of course, there is the ultimate question: Why would you lock it in the first place?

    I had about 10 minutes to exercise before I had to pick up my two older daughters from school yesterday. It was a busier day than usual for me with a couple of meetings besides my regular work.

    Years ago, I would have put off my workout and would have left things for the next day. But since it was a busy day as well, I knew that I may not have all that much time either. So, I picked up my kettle-bell (哑铃) and went to town for 4 minutes.

    See, 4 minutes, if that's all you've got, is enough to give your body a great fat-burning exercise. How did I get a killer workout in 4 minutes? I used a training workout discovered 10 years ago by a Japanese Sports Scientist called a TABATA.

    It includes 20-second periods of warm-up, followed by 10-second periods of rest and 4-minute straight exercise. How is a 4-minute exercise able to burn fat? It all depends on the quality of work you do. Not on the quantity. Here's how I did it yesterday.

    You should never forget your warm-up. A TABATA workout is 20 seconds of 2-arm Kettle-bell swings, 10 seconds rest, 20 seconds push-ups, and 10 seconds rest. You should do those 4 rounds. That's it. I was done in a total time of 8 minutes by the time and when I got to school my heart was still pumping pretty hard.

    A healthy body is needed for studying and working, and efficiency (效率) is the key to building a great body in the least amount (数量) of time possible and you can't get more efficient than a 4-minute workout.

    Once upon a time, two brothers who lived on neighboring farms fell into conflict(冲突) . It was the first serious one between them in 40 years of farming peacefully side by side. In the end, they fell apart.

    One morning, a man with a carpenter's toolbox came for some work. The elder brother said, "I have a job for you. Look at the farm across the creek(河沟). My younger brother lives there. It was he who used his bulldozer(推土机)to dig the creek last week to spite(刁难) me. So I want you to build me a fence, an 8 – foot – high fence, in order not to see his place any more." The carpenter smiled and said, "I see. I'll try to do a job that satisfies you." Then the elder brother went downtown.

    At sunset when the farmer returned, the carpenter had just finished his job. The farmer's eyes opened wide! To his surprise, there was no fence there at all! Instead, there was a bridge stretching from one side of the creek to the other! A fine piece of work! He saw his younger brother coming to him with the hands outstretching. The brothers stood at each end of the bridge, and then they met in the middle, taking each other's hands. They turned to see the carpenter lift his toolbox on his shoulder.

"No, wait! Stay a few days. I've a lot of other work for you," said the elder brother. "I'd love to stay on," the carpenter said, "but I have so many more bridges to build."
