"Bill, you never miss！"Joe said admiringly. "Unless I'm in a real game, "Bill complained. "Then I miss all the time. " Joe knew that Bill was right. Bill performed much better when he was having fun with Joe in the schoolyard than he did when he was playing for the school team in front of a large crowd. " Maybe you just need to practice more, "Joe suggested. "But I practice all the time with you！"Bill said. He shook his head. " I just can't play well when people are watching me. " "You play well when I'm watching, " Joe pointed out. "That's because I've known you since we were five years old, "Bill said with a smile. " I'm just not comfortable playing when other people are around. " Joe nodded and understood, but he also had an idea.

The next day Joe and Bill met in the schoolyard again to practice. After a few minutes, Joe excused himself. " Practice without me, "Joe said to his friend. "I'll be back in a minute. "

Joe hurried through the school building, gathering together whomever he could find-two students, a math teacher, two secretaries, and a coach. When Joe explained why he needed them, everyone was happy to help. Joe reminded（提醒）the group to stay quiet as they all went toward the school's basketball court. As Joe had hoped, Bill was still practicing basketball. He made five baskets in a row without noticing the silent people standing behind him.

"Hey, Bill" Joe called out finally. Bill turned. A look of surprise came over his face. "I just wanted to show you that you could play well with people watching you," Joe said. "Now you'll have nothing to worry about for the next game!"

   When it comes to exercise，most of us fit into one of the two groups — those who keep a regular exercise habit and those who think about being more active but can’t seem to have a plan to do it consistently. Whatever your attitude to exercise，there’s another form of physical activity that many of us car-loving people can do to get enough movement in general.

Studies have shown that putting away your car and walking, biking or taking public transport to work can have a significant positive influence on your health by improving spirits, reducing body weight and lowering the risk of heart disease.

It’s not surprising that taking a bus or a train regularly leads to a more physically active lifestyle. Just think about what comes with using public transport. Those who travel to work without a car walk to stations, climb stairs, often stand while waiting for their bus or train, and then finally travel on foot or by bicycle to their destination. Such active transport can make up for the inactive time spent in work and school environments.

There’s no doubt that the improving public transport system in the city is influencing the way people work and live. But though the public transport system is improving, it is not within easy reach of everyone who would like to use it.

Bike-sharing programs are also growing in popularity（普及）and helping to bridge a gap in the crowded city public transport system. These programs allow users to easily book, ride and return a borrowed bike. Bike-sharing programs help people who might still need to travel some distance between the end of the bus or the underground line and their final destination. They also offer an opportunity to residents and visitors to travel freely around the city without being trapped in a car.
