As it is known to us, fewer and fewer students do sports regularly, what makes them weak and easily tired. There are many reasons about this. First of all, some of the students complained that they have too many homework, resulting in less time to take exercise. Beside, some of them think that it is very difficulty for them to keep doing exercise, because it is a very hard thing.
Because lack of physical activities, many students are in poor health. I suggest that our school must take measures to encourage more students to take part in sports. For us students, no matter what busy we are, it is necessary to spare some time to do exercise.
2 . Erica and Steve Lineberry have been rock climbing since 2005. They were first introduced to it while visiting a family in Montana. Now they are at climbing centers, like Inner Peaks in Charlotte, three times a week, and on weekends they climb outdoors.
Steve said they first started climbing as part of their exercise. Years later, he lost 60 pounds. But as the couple’s interest in the sport grew, they consulted some mentors and started climbing outdoors.
Then Erica got pregnant. “Most people think that rock climbing and pregnancy don’t go very well together,” Erica said. But with lots of places to go, Erica kept climbing through her pregnancy. Then her son, Ca-naan, was born. She says the baby immediately started participating in the family sport. “He went to the gym the first time with us at four weeks old, and then we took our first outdoor trip, just a day trip, at six weeks old with him.”
Now Canaan is three-year-old, and Erica is once again pregnant: 7 months along. During her first preg-nancy, she blogged about climbing while pregnant. Now her Cragmama. com website is a top resource for families who rock climb. Erica said, “I think a lot of people will say, they’ll wait a few years until they get into an easier age or an easier life phase with their kids. And I think if they wait for that they’re going to wait forever. ” Her message to women is to quickly climb back into the things you love; and that your life is not over once you are a mother.
Cragmama.com website is quickly becoming the face of mommy rock climbing. She contributes to a handful of climbing magazines. Outdoor equipment companies ask her to wear and use their gear (设备). And her website is a popular resource for families who are not only interested in climbing with their children, but also interested in taking on other adventures too.

4 . Recently a study, led by Pedro Hallal of the Federal University of Pelotas, suggests that nearly a third of adults,31%, are not getting enough exercise. That rates of exercise have declined is hardly a new discovery. Since the beginning of the industrial revolution, technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently has enough good data been collected from enough places to carry out the sort of analysis Dr Hallal and his colleagues have engaged in.
There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men-34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, exercise more than their male countrymen.
Malta wins the race for the most slothful country, with 72%of adults getting too little exercise，and Swaziland and Saudi Arabia are in close behind，with 69%.In Bangladesh，just 5%of adults fail to exercise enough. Surprisingly，six in ten Americans are active enough according to Dr Hallal's study，compared with fewer than four in ten British men.
These high rates of inactivity are worrying. Human beings seem to have evolved（进化）to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. Actually lack of enough activity these days has nearly the same effect on lifespan（寿命）as smoking.
