All parents know exercise is important for children: It can lower heart risks, control weight,and help kids do better in school. Plus, outdoor activities at an early age can go a long way toward helping children form healthy habits for life. In other words, exercise is needed for healthy development. But don’t expect kids to understand about those things. Some kids just aren’t into exercise, but that shouldn’t mean they have to be addicted to the TV. So parents could do something to help inactive son or daughter fall in love with physical activity.

If parents sit in front of the TV every night, a bag of chips in hand, kids aren’t likely to respect restrictions (限制) you set on their screen time either. So check your own viewing behavior, and serve as a role model by putting physical activity into your everyday life. When you can, walk instead of driving. Regularly participate in activities that you enjoy and let your kids see — and hear about — how much you enjoy them. In this way, they may “do as the Romans do”. Make sure that children’s fitness is included in the family schedule in the same way that school, work, shopping, and family gatherings find their way onto the calendar. You and your children are more likely to stick to an exercise plan if you incorporate it into your life on a routine basis. And your children will begin to expect and accept that Sunday morning usually means a hike ride, and a couple of nights after dinner the family takes a light walk through the neighborhood.

Children who aren’t naturally good at physical activities may be self-conscious about their lack of physical skills and even fear public failure. These kids need all the support and encouragement from parents. Negative comments don’t work and will only serve to make your child feel bad. Remember, acknowledge the effort — choosing to be active or trying to improve a skill — rather than the outcome.

3 . Physical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.

Today many people don’t do sports. But as is known to all. doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.

High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.

The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure (措施) to encourage physical activities and help teens have healthy weights.

Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.

According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activities each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.

The FIFA World Cup attracted worldwide attention. But have you ever considered     1     watching the World Cup might affect your health?

Since the two students can successfully get rid of their bad lifestyle, believe you can as well. Then be the change you want to see in the world.

I used to hate running. It seemed too hard, and pushing outside my comfort zone was not something I was raised to do.

In fact, I wouldn't have become a runner if it weren't for my husband Charles. He had been a serious competitive runner for many years. But several years ago, he quitted running for some reason. After our marriage, he wouldn't stop talking about how much he missed it.

"So start running again, why don't you?" I was getting tired of hearing about it.

So he picked it up again, and after a year or so, I started to join him at the track. Just a few weeks later, Charles signed us both up for a five-kilometer race in my city. I hesitated about doing it. After all, it was too soon.

But on the race day, there I was. As soon as the gun went off, thousands of runners pushed forward.

The first kilometer was too tough for me.

"I don't think I'm going to make it." I was already breathing heavily and painfully aware of the group of runners pounding past me.

"No, you're doing great", said Charles. He was trying to encourage me, to get me focused on something other than my discomfort.

"I can't," I said, in a weak voice.

He tried a different way to persuade me. "Just make it to that house and let's see how you feel." I had to continue, sweating all over.

After another minute I saw the three-kilometer mark. All I could think of was that I was dying and that my husband was torturing (折磨)me.

Miserable doesn't even begin to describe how I felt. And there was pain, so much pain that I was on the verge of breakdown.

"You'll be fine. You've got less than a kilometer to go," Charles shouted loudly.

My 11-year-old daughter, Elizabeth, started to talk about quitting swimming, which broke my heart because she loves swimming. So when the swim season began, I cut a deal with her. She would practice three times a week and try really hard. I wouldn't make her compete in the swim meets. Elizabeth does not like swim meets. She gets horribly nervous but not because she wants to win. She doesn't care if she wins.

Recently, Elizabeth's team announced a special swim night： Members 11 and older would swim a timed 50 meters relay. It wasn't exactly a meet, because it would involve only team members. That was my view. Elizabeth argued that it absolutely was a meet because there would be races. I told Elizabeth I really wanted her to go. She fought back angrily but finally agreed.

When the day of the special swim night arrived Elizabeth was nervous. She was the youngest person and shorter by at least a foot than most of the other kids. She panicked when it was time for the T-shirt relay. The relay works like this： One person from each relay team puts on a T-shirt, a pair of socks» and a swim cap； swims 50 meters; and gets out of the pool. She takes off the clothes and puts them on the next person, who then swims 50 meters. This continues until everyone on the team has completed a lap.

Then it was Elizabeth's turn to swim. She seemed to swim faster in the T-shirt and socks than she did when she wasn't wearing them. Approaching the halfway mark, Elizabeth was in the lead. Suddenly, somebody noticed that one of Elizabeth's socks had fallen off and was floating （漂）in the pool. "She has to get that sock on before the end of the race," a swimming official told Elizabeth's team, ^“or you will be disqualified.^”

Everybody on her team started screaming ^“Elizabeth! Get the sock!”

On the ride home, she shared her moment of winning again and again.
