Skateboarding has become one of several non-traditional activities that PE teachers around America are introducing to inspire kids to exercise regularly. Some PE classes feature in-line（滚轮） skating, yoga, and even rock climbing. Experts have called those types of activities “the new PE”.
Such activities are part of a larger effort to help kids develop lifelong fitness habits and to keep them from becoming overweight. Now, 9 million U.S. children and teens are overweight. Obesity (肥胖) can lead to health problems such as diabetes and heart disease later in life.
"Our children and youth are becoming unhealthy and obese," says Johnson. "Skateboarding is a great activity that keeps kids doing physical movement and gives them new skills and interest."
Some schools don't allow skateboarding because they say it is dangerous. Tim, however, argues that regular practice eliminates a great deal of the danger. "We teach students how to do it and how to do it safely," he says.
Some people say skateboarding teaches life lessons. “Skateboarding teaches kids to believe that if they stick with something they will finally succeed. ”says education expert Richard Savor from College in Portland.
Skateboarding inspires kids not to give up in learning difficult skills. "It's natural for kids to want to learn and get better at things," adds Tim. "When it comes to skateboarding, they'll try a trick hundreds of times before they succeed." That same effort could be made in schoolwork.
Eric Brown agrees that skateboarding requires kids to stop saying a task is too hard for them. "A baby will attempt to walk 600 to 900 times before he or she is successful," says Eric, "We tell students that they shouldn't say 'I can't do it' unless they've tried 600 to 900 times.

Writer and power chair adventurer Mary Laver has not walked for twenty years. Yet the cheerful and positive 60 year old is not only refusing to let her disability get her down ---- she is also planning to cross the length of Britain in a power wheelchair.
Getting ready for the trip is not easy. She has already run into many problems - not least officials and organizations who view her as a health and safety risk. One police officer wrote to Mary requesting:
1. The proposed route through our area with road numbers.
2. The dates and times each day that this will be taking place.
3. The location details of the proposed overnight stops.
4. The names and mobile phone contact details of the Support Crew.
Another police officer asked her to travel off road! As Mary told me, this was unacceptable - as a power wheelchair user with limited movement she needs to be"gettable".
There are other problems in her way though - she is, after all, in her 60’s and has severe rheumatoid arthritis(风湿性关节炎). However, unlike many other people with arthritis, she is no longer in pain.
"When you are in a power chair and it is going at eight miles an hour, believe me it feels fast … to me it is the Formula One(一级方程式赛车) chair of electric wheelchairs."
At the end of the interview, I asked Mary if she had a message for any other power chair users who wanted to do a challenge, and her reply was simple："Just do it!"
【小题1】What is Mary Laver planning to do？
