2 . 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 study 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 (肥胖症). 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 video games and computer activities, means many teens don’t get their required exercise. PE classes act as a public health measure to encourage physical activities and help teens have healthy weights.

Not doing sports increases teens’ risk 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 hindered 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 activity 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.

3 . Years ago, I could not stick to exercising until I bought a CD called I Enjoy Exercise. I listened to it every day. I bought the CD because I wanted to run in a race and hopefully win!

I had assured my 10-year-old son Todd that I would run in a race with him. Unfortunately, however, when that race came, his left leg was hurt in a car accident. Without him running with me, although I took part in that race, I didn’t do quite well in it.

While Todd couldn’t run together with me because of his injury (受伤), he never forgot the promise I made for him. He was always asking me whether I would keep my promise when he recovered in the future. So I decided I was going to train and go all out to win the next race. What I needed was motivation (动力). It happened that one of my friends mentioned the CD which he liked very much, saying that he got a lot from the music in it when feeling down. So I bought it and listened to it while exercising every day.

What happened to my thinking was amazing as I listened to it daily. I started to think about the repeated words on the CD — “I enjoy exercise”. Instead of dreading exercise, I was thinking, “I enjoy exercise.”

I found out how important words are that we play in our minds every day. I went from a person who seldom exercised to someone who started to exercise daily. Just think how our lives will improve if we reflect on the uplifting words of the famous works. I have found the positive messages have greatly inspired me and then changed my life.

How did I do in that race, you might be thinking? I actually became the champion in my age group.

4 . Running can be a polarizing (两极分化的) subject. Most people fall into one of two camps: those who love running every morning, and those who would sooner do anything to avoid it. For most of my life, I was planted in the second camp.

I always hated running. I remembered entering a neighborhood 5K race with my dad at age 12; I also remembered that I came in last in the race, followed by only the police car driving patiently behind me. Three years later, I didn’t make the junior volleyball team because I couldn’t run a mile in under 10 minutes. Every time I ran, I felt as though failure — in some form or other — was the only possible result.

The summer after my freshman year, though, I took a job at a summer camp in Connecticut, where I got paid to be a kid again. I spent my days keeping an eye on different camp activities. When it came to exercise, running was my only choice. So, I made a promise myself: Every day, I would run for a while. By most runners’ standards, it wasn’t far; I guessed it was only about a mile. But I decided to do it every day, no matter how long it took. The exercise lasted for 61 days — the entire time I spent at camp that summer.

I started to feel better about myself. But to my great surprise, I learned to love running, too. I went from fearing the sport to loving it. I’ve finished seven marathons (马拉松赛跑) and more shorter races than I can remember, and now I am a running coach. These were the secrets I discovered to changing my way of looking at life.

5 . The annual marathon in my town occurred as scheduled. My job was to follow behind the runners in an ambulance in case any of them needed medical attention. As the athletes began to pace themselves, the front runners started to disappear. It was then that my eyes were drawn to the woman in blue running shorts and a baggy white T-shirt.

I knew we were already watching our “last runner”. Her feet turned in, yet her left knee was turned out. Her legs were so crippled and bent that it seemed impossible for her to walk, let alone run a marathon.

The driver and I watched in silence as she slowly moved forward. We would move forward a little bit, then stop and wait for her to gain some distance. Then we’ d slowly move forward a little bit more. As I watched her struggle to put one foot in front of the other, I found myself expecting her and urging her forward. I wanted her to stop, and at the same time, I hoped that she wouldn’t.

Finally she was the only runner left in sight. I sat on the edge of my seat and watched with respect and amazement as she pushed forward with strong determination through the last miles. When the finish line came into sight, the cheering crowds had long gone home. Yet she didn’t give up and crossed the line.

I don’t know this woman’s name, but that day she became a part of my life — a part I often depend on. For her, it wasn’t about beating the other runners or winning a prize. It was about finishing what she had set out to do. When I think things are too difficult or I get those “I-just-can’t-do-it,” I think of the last runner. Then I realize how easy the task before me really is.

6 . All over the world people enjoy sports. Sports help to keep people healthy and happy, and to live longer.     1    They buy tickets or turn on their TVs to watch the games. Often they get very excited when their player or team wins.

    2    Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers. What fun it is to jump into a pool or lake, whether in China, Egypt or Italy!     3    Think how many lovers to skate or ski in Japan, Norway or Canada.

Some sports or game go back thousands of years, like running or jumping. Chinese Kungfu, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet.     4    Water-skiing is one of the newest in the family of sports.

People from different countries may not be able to understand each other, but after a game together they often become good friends.     5    One learns to fight hard but fight fair, to win without pride and to lose with grace.

8 . Many people make it our New Year decision to get more active — but maybe you have to spend large sums in gyms.     1     But by changing that plan for these following ideas, you can not only increase your energy but save your money.

Get started with running. Going for a jog costs nothing and is one of the easiest ways to build up your body. If running seems like a task, why not try an app to add to pleasure? I love a sports app called RockMyRun. It understands your personal pace and then matches the music beat to it.     2    

Follow fitness bloggers. The Internet is full of fitness bloggers competing for likes and followers. They often post some free short videos showing how they are exercising.     3    For guidance from a personal trainer, which may even cost£ 30 to 65 an hour.

Take resistance training(抗阻力训练).     4     You can use them to increase your resistance training — zero gym required. Tins(罐头) of beans or tomatoes can be used as smaller weights, while 2-litre drink bottles offer heavier resistance.

    5     It may be slightly cold to work out there, but most of them are nonprofit community outdoor gyms across the country. With everything you may need, they provide various training workouts. Find your nearest outdoor gym at tgogc. com.

As a player, Lang Ping brought honor and glory to her country.     1     she led the China’s women’s volleyball team to medals at world championships and the Olympics. As a person, Lang Ping is loved by fans     2     . When the Chinese team was preparing for the 2015 World Cup, her determination was tested. The team that Lang Ping had built     3     . One of the best players had been injured, and the team captain had to leave because of heart problems. Losing two important players was     4     , but Lang Ping did not lose heart. She had faced difficulties before, and she knew that her young players could win if they worked together as a team. Two weeks later, they were     5     ! Then in 2016, Lang Ping led her volleyball team to Olympic gold in Brazil.

10 . Who to Believe?

“My doctors told me I would never walk again because of the illness. My mother told me I would. I believed my mother.”

Wilma Rudolph was born in 1940 into a very large and poor African-American family in Tennessee. When she was four years old, a deadly _________ made her left leg useless. She had to wear an iron leg brace (固定器). Her doctors told her she would never _________ like a normal person without the brace. _________ she was fortunate in having a mother who encouraged her to have faith and _________ .

At nine years of age, the little girl _________ the leg brace and took the step that her doctors had said was _________ . Then she got the incredible idea that she would like to be the world’s greatest woman _________ . Now, what could she mean- be a professional sportswoman with a useless leg?

At the age of thirteen, she began to enter races, but she came in last in every race. Everyone begged her to   _________ it. One day, however, she came in next to last. Then there came a day when she won a race. From then on, she   _________ every race that she entered.

In 1957, Wilma went to Tennessee State University, where she met a __________ named Ed Temple. He trained her so well that in 1960 she went to the Olympic Games in Rome.

Then came the 400-metre relay. It would be Wilma __________ Jutta. When the third runner handed the baton (接力棒) to Wilma, she was so excited that she __________ it, and Wilma saw Jutta taking off down the track. It was impossible that anybody could catch this girl. But Wilma did just that! Wilma Rudolph had __________ her third Olympic gold medal in the 17th Olympic Games.

That day Wilma made history as she became the first woman to win three gold medals in the same Olympic Games. Later she said. “The success can’t be reached without the __________ . I have spent a lifetime trying to share my story so that other young women have a chance to reach their __________ ”
