"I felt a little (使人不舒服的) when I walked，into the civic center at first, because I was not very good at communicating with people, especially with strangers. To my surprise and relief, I found there were many other elderly people just me in the center. Through taking part in different activities, we became friends. B, I also attended different classes to learn new skills. These skills are very useful in my daily life. This makes me realize the (力量) of knowledge once again.

Chris Haas, a 9-year-old kid, noticed many of his classmates holding basketballs incorrectly and, as a result, not shooting (投篮) very well during a school basketball practice. He was the son of a basketball coach and knew a thing or two on the right way to aim and shoot. After trying to show his classmates the right way to hold a ball, he came up with his invention: the hands-on basketball. 

The hands-on basketball is a basketball training tool for kids. It has hands painted on it, showing the correct positions to hold the ball while trying to shoot. However, when he first took his invention to a kids' invention competition at his school that year, he didn't win. But with his teachers' and family's encouragement, he went on to patent (获得专利权) his idea and he made it. Then he went to several sports companies and asked whether they would be interested in making and selling his invention. None of them was. 

Chris didn't give up and a year and a half later, luckily, his invention won the attention of a sports company. And it was soon available in the market. After that he won tons of prizes. The hands-on basketball is now sold successfully around the world.

But being a famous person was just one-of the new challenges Chris had to face after he sold his invention. Chris promoted (宣传) his invention by traveling around and making appearances in cities, like New York, Las Vegas. He also had to decide how to use his money wisely. Each year, he gives away much money to children's organizations. These days, Chris is an active basketball player and writer of the book一Shooting for Your Dreams.
