When I was watching a sports event yesterday, I met with an amazing sight. It was not a gold medal, or a world record broken, but a show of pure courage and determination.

    The event was swimming. I watched a man dive off the blocks and knew right away that something was wrong. I'm not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold — his arms were waving in an attempt at freestyle.

    I heard the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes (划水) and you could tell he was worn out. But in those few awkward strokes, the crowd changed. No longer were they laughing, but beginning to cheer. Some even began to stand and yell things like, "Come on, you can do it!" He did. The crowd went wild.

    Just a short year ago, he had never even swum, let alone race. His country had been invited to take part in the event. Even though he recorded the slowest time, this man gave more heart than any of the other competitors—a man that gave his all, knowing that he had no chance but to compete because of the spirit of the games.

    Going green seems to be fad (时尚) for a lot of people these days. Whether that is good or bad, we can't really say, but for the two of us, going green is not a fad but a lifestyle.

    On April 22, 2011, we decided to go green every single day for an entire year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.

    With the idea of going green every single day for a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps.

    Over the course of Our Green Year, we completely changed our lifestyle. We now shop at organic(有机的)stores. We consume less meat, choosing green food. We have greatly reduced our buying we don't need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.

    Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.

    Philadelphia offers a ton of attractions that are suitable for people of every age and here are some family—friendly attractions.

    Spruce Street Harbor Park

    Spruce Street Harbor Park, one of the best urban beaches in America, is an outdoor heaven on the Delaware River waterfront. Visitors can relax in a hammock, play on the playgrounds, and play games like table tennis and giant chess. Don't miss out on the park at night, when colorful LED lights hanging from treetops make the entire area bright.

    Blue Cross River Rink

    Offering ice skating in the winter and roller skating in the summer, Blue Cross River Rink creates a fun, outdoor experience for the whole family. Visitors can play on the nine-hole mini-golf course during the summer, and enjoy eats and drinks from the on-site(现场的)bar and restaurant all year round.

    Sesame Place

    Big Bird, Elmo and the other stars of Sesame Street come out and play at Sesame Place, the only theme park in the nation starring the popular TV show's most lovable characters. A water park, interactive activities, parades, fireworks and shows add to the fun.

    Once Upon a Nation Storytelling Benches

    On summer days, uniformed and professional storytellers at 13 storytelling benches throughout Philadelphia's Historic District entertain visitors with true, free, three-to-five minute tales about the colonial(殖民的)era as part of Once Upon a Nation. Children can pick up a Story Flag at any storytelling bench, and then collect a star from every storyteller on their journeys. Flags with all the stars can get free rides on the Parx Liberty Carousel at Franklin Square.

    Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

    Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球场）in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

    There are many environment-friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

    Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements（代替物）for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

    Craft (手工艺）is becoming a heritage industry — but a record of disappearing skills might just come in handy in the future.

    Mr. Lobb (of John Lobb the bootmaker) mentioned that custom clothing and shoe-making were once the norm for everyone. How come，then，today a pair of normal Lobbs would set you back over £2,000? The price has obviously gone up because of lack of competition and higher wages，but would custom clothing once again be affordable to all if the demand was there? Do we just wave goodbye to these skills，or should we fight to maintain them?

    The disposable (一次性的）culture we “enjoy” today has existed in our life for almost two generations now. We like our products to be made by either a robot or invisible，cheap hands so that we can accumulate them cheaply and frequently. The concept of “craft” is something that's now largely considered to be strange，and seems to be limited to museums and dusty, independent shops. Hobby crafts such as knitting do undergo revivals (复兴)from time to time，but I think that's because they are seen as short-lived fashionable leisure pursuits rather than a craft worthy of revivals on a commercially feasible (可行的)scale.

To drive a revival in any of these crafts, you would probably need to apply the same marketing techniques that are used to sell any other items today. The consumer must believe that they just have to have it. If they don't have it now, it will either go up in price or go out of fashion — both reasons enough in themselves for a shopper to act.

    But does it finally matter if these skills will no longer serve any practicable use in the decades to come? I don't know the answer to that，but I have long thought it would be a good idea if we “banked” these skills somehow，just as we are not attempting to do with seeds. You just never know whether we'll need them in the future. Maybe it's time to establish a worldwide network of volunteers to record，through the written words and videos，as many of these dying skills as possible. Actually, a rough look on YouTube fills me with hope that an army of willing volunteers is probably out there already and just needs someone or something to gather them together.

    Imagine a small group of people with a shared passion for the same craft. They all have different skills and approaches, but they come together to share skills, share stories, and share in the joy of making something.

    Modern maker culture is filling headlines and lab spaces all over the world. The way makers communicate with each other has changed over time. In the past, skills mainly came from personal sit-downs with members of the group. But sometimes a teacher wasn't available, or the one available didn't know how to do the skill others wanted to learn.

    Today a teacher doesn't even have to be in the same country or occupy the same decade as the students. Thanks to the work of people who take the time to break down and share the details of their craft, an interested individual can learn anything. Guides may range from videos to diagrams and text. Regardless of the media, maker resources are meant to be shared.

    One of the features of the maker movement is the crossover between different interests. Perhaps a passion for cars and for leather craft can result in a truly custom interior (定制的内饰). Perhaps a love of knitting (编织)and robotics will result in a tiny ——but very mobile ——robotic furry cat.

    And once you have started your creation, finding a community to share with is no longer limited to the people nearby. Modern makers have been sharing videos of their progress online for years, contributing greatly to the rapid spread of the maker movement. As different as the participants might be, they share enthusiasm, support, and a willingness to try.

    Imagine making a ping-pong table together with your makers' team. One group builds the basic frame. Another group takes on the responsibility of painting. You knit the net. There is joy in just giving it a try. It will remind you of childhood creations. Whether you are an experienced programmer or just picking up a hammer for the first time, it is never a bad time to come up with an idea, try something, and share the results.
