Baseball is one of the favorite sports in the USA. Children play baseball in sports fields or in parks. At summer picnics, there is often informal (非正式的) baseball game. Boys and girls, young and old take turns to bat. Each team has 9 players.
   American football is perhaps the most popular sport in the USA. The football season begins when the baseball season ends. More people are interested in football than baseball. When there is an important game, thousands of people sit beside the radio or in front of the television to hear the result.

    Service on the 102-km high-speed railway between Shenzhen and Guangzhou started on December 26, 2011. A non-stop trip between the Guangzhou South Station and the Shenzhen North Station takes 35 minutes at full speed.

    The train runs at the highest speed of 300 km per hour. All 36 pairs of trains run every day. A one-way first-class ticket costs 100 yuan. A second-class one costs 75 yuan, 5 yuan cheaper than a second-class ticket on the slower line.

    A high-speed train has 556 seats, including 16 seats in the VIP rooms and 50 in the first-class carriage (车厢). It offers more advanced facilities (先进的设施). For example, the seats are more comfortable, there are toilets for the disabled (残疾人), and there are power outlets (电源插座) in the first-class carriage.

    The high-speed service between Guangzhou and Shenzhen will be a convenient choice for many people. “I won't need to travel to the Guangzhou East Station to take a train to Shenzhen,” said Wang Yi, who lives in Panyu district in Guangzhou.

    Many people still prefer the slower trains, because the terminals (终点站) of the high-speed trains are far away from the centres of both cities. “I would not like to take a high-speed train to Shenzhen. I live in the centre of Guangzhou. First I have to get to the Guangzhou South Station. It is a waste of time for me,” said Zhang Lu.

    I've always wanted to try rock climbing, but never had the time or money for it. But I've discovered a way to experience the thrill(兴奋，紧张)of climbing rock, without climbing real rock. Indoor climbing is an easy and exciting way to get a taste of rock climbing. And it is also much cheaper and safer！Indoor climbers don't climb on real rock, but on a plastic wall. You can probably find a climbing wall near you. Many gyms, schools and camps have one.

    You can climb indoors at any time of the year, no matter how the weather is. It is usually not expensive. Most gyms provide the equipment you need. The convenience of indoor climbing is one reason why it has become so popular. But the main reason people climb is for the rush(刺激感)they get. When I stand at the foot of the wall and look up. I'm always scared, But once I start climbing, fear changes to determination. With my heart pounding(怦怦地跳), I reach the top and look down. I can't stop grinning(咧嘴笑). I did it!

    Indoor climbing is a great workout. Climbing uses muscles that are hard to exercise, especially those in the shoulders, arms, chest and back. Many people say climbing makes exercise fun. Most gyms have several climbing walls with various degrees of difficulty. The easier ones are like climbing a ladder. The difficult ones bulge out(凸出)in places so that climbers must sometimes climb parallel(平行的)with the floor.

    Although gym climbing is easier and safer than real rock climbing, you should still be careful. Always climb with a partner. As you climb, your partner pulls your climbing rope through something called a belay device(绳索控制器). The belay catches you if you slip. But make sure your partner know how to use this equipment. And if you are a first-time climber, get some instruction before you begin.

    How do people find theirinner talent (潜力)? British author KennethRobinson talked about this at TED. He told the story of Gillian Lynne, a dancerand a choreographer (编舞者) who has worked on manyfamous musicals (音乐剧).

    Gillian Lynne never didwell in school as a child. She couldn't sit for long and often found herselfmoving restlessly (不安地). Her mother was reallyworried about her. She took Lynne to a doctor and told the doctor the problemsLynne was having in school. Then, the doctor said to Lynne, "I need tospeak to your mother first. Wait here."

    As they left the room,the doctor turned on the radio. He then said to Lynne's mother, "Juststand and watch her." Later they found Lynne start dancing to the music onthe radio.

    The doctor then turnedto Lynne's mother and said, "Mrs. Lynne, your daughter isn't sick. She's adancer. Take her to a dance school."

    So the mother did. Lynnefound there were many people like her in the new dance school. They all had tomove their bodies to think. Lynne later went to the Royal Ballet School (皇家芭蕾学校) one of the world's greatest dance schools, and became a greatdancer, she worked on some of the most successful musicals in history, such asCats and Phantom of the Opera (《歌剧魅影》). It is hard to believethat years ago, somebody else would just put her on medication (药物治疗) and tell her to calm down.
