1 . 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.

2 . It is very obvious that some of the world's top-performing athletes have and feel something deep inside their core that regular athletes simply don't.     1     and are constantly pushing themselves to become better than yesterday. These athletes are the types of people that inspire and motivate other people to really give it their all and if you analyse them you will see that no matter how great they are, they are constantly trying to improve something new that is going to take them to the next level.

First of all, the pursuit (追求) of health and fitness should always start with goal setting.     2    , they have an exact picture of what they are trying to reach and they make sure that their goals are concrete and measurable, so they always have an idea of how far they are from their goals.

These athletes don't limit themselves when it comes to their health accomplishments.     3     even though they really don't know how they are going to reach them at first. They know that by setting high goals their motivation levels will explode and they will be even more fired up to find a way that will make them reach their “impossible” goals. For these guys, nothing is impossible when it comes to health and fitness.

    4     They push themselves as hard as they can and constantly try to reach new levels of success. For the outside world, it might be hard to understand how they can push themselves this hard, but for these super athletes, it is just a game.     5     that they don't even see it as work, they see the whole thing as fun.

A．Last but not least, they are extremely excited and driven by their goals.

B．They always give it their all.

C．Their goals excite and motivate them so much

D．They try their best to shape their bodies

E．Compared to regular athletes who don't set concrete (具体的) goals and monitor them

F．This is what really fuels and drives them when training

G．They set really high goals

3 . Rachel sat on the back steps, pounding her fist into her softball (垒球) glove and staring at the old tire swing in the backyard. Tryouts for the softball team were next week, and she desperately needed someone to act as catcher while she worked on her pitching (投，击). Unfortunately her father was away on business, and her mother was embroiled in final exams. Her mother was so wrapped up in studying that she barely had time to eat. Rachel wondered what to do as she woefully stoked her dog Kit.

Her grandfather came around the comer of the house and stopped when he saw Rachel. “Why the long face?” he asked. “Pitching tryouts are next week. Grandpa,” she explained. “And I need to be in top form-four girls are trying out for only three pitching positions. But there's no one around who can practice with me.” She tossed the softball to Kit, who smartly leapt into the air and easily caught the ball with her teeth. Kit eagerly ran back to Rachel and placed the ball at her feet.

Grandpa offered to help. Rachel swallowed hard. Her grandfather had injured his hip and had to stay in a wheelchair now. She certainly didn't want to cause him further injury by hurling fast pitches at him, but how could she refuse his offer without hunting him?

Her grandfather slowly moved his wheelchair into the backyard and told Rachel to stand where he pointed. Rachel obeyed quickly, and Kit followed her. “Take a look at that tire swing. Rachel. It looks like the batter's (击球手) strike zone, wouldn't you say?” asked her grandfather. Rachel eyed the swing and nodded slowly. She said, “So if my pitch makes it through the tire, I'm almost certainly throwing a strike. Everything else is probably outside the strike zone.” Her grandfather smiled and added, “We can always raise or lower the tire to simulate (模拟) the strike zones of taller or shorter batters.” “But what about a catcher?” asked Rachel. “I don't want to keep fetching my own pitches.” “I've got the perfect solution to your problem,” said her grandfather, who moved forward to throw Rachel's softball across the yard. “Go get it, Kit!” he shouted. The excellent dog ran after the ball, picked it up in her jaws, end bounded back with her prize. Rachel gave him a grateful hug and said, “Grandpa, I think my chances of making the team just improved one hundred per cent!”

4 . William Purkey, a well-known professor of education, once said, "Dance like no one is watching, love like you'll never be hurt, sing like no one is listening, and live like it's heaven on earth." It seems like the perfect life philosophy (哲理)---and one I've learned to apply to running over the year.

But I didn't always feel this way. In my early days, when I weighed 240 pounds, I ran like everyone was watching---and judging. If I was on a run and saw a car approaching, I'd stop and pretend I was looking for something I'd lost. I bought the high-tech gear and clothes that I thought would make people believe I was a runner. And I didn't know if the expensive shoes I was wearing were the right kind for me---I just wanted to look like I fit in with this group.

To be honest, I felt a certain satisfaction in believing that someone was watching. I really thought that other people cared about my performance. The best example of this was a combined, two-lap marathon(马拉松长跑)in Florence, Italy. As I approached finishing line, the crowd began to cheer. I was surprised. Here I was, thousands of miles from home, and the Italians were shouting for “IIPenguino.”

About 20 yards from the finishing ,the truth set in when the winner of the full marathon went past me as I was finishing the marathon No one was cheering for me. no one probably even noticed that I was finishing. I couldn't help but smile at my own illusion of self-importance.

That's when I realized I had been running for every reason except the right one. I ran to make other people happy, ran to live up to their expectations. But no one was watching---no cared. So I decided I was going to run for me---just me---and gained a new enjoyment from the sport I hadn't truly experienced yet. I've learned to run like no one is watching.

So if you see me at race, and I look like a 60-year-old guy wadding(蹒跚) along, don't worry. I'm fine. The miracle isn't that I finished. The miracle is that I had the courage to start.

5 . Are you trying to find the best time for exercise?     1     Follow these tips to figure out what fitness routine works best for you.

Dawn, dusk or dead of night — when’s the best time to work out? Well, that depends on when’s the best time for you, because the benefits of physical activity depend upon how consistent you are.     2     But if you’re not a morning person, it may not work for you to try to get up at dawn to work out. The key is to do what’s most likely to work for you consistently.

    3     If you find that working out too late in the evening keeps you from falling asleep easily, shift your exercise session earlier in the day or try less intense, more mindful forms of movement.

To stay motivated, choose activities you enjoy. If you’re a social person, do something that engages you socially. Take a group exercise class, join a recreational team or walk with a group of friends. If you prefer having time alone, walking, swimming or biking solo might be a better fit for you.     4    

There are so many choices.     5     Having a variety of fitness activities to choose from may keep you from getting bored or burnt out.

A．The truth is, it’s personal!

B．Don’t limit yourself to just one.

C．There are other important considerations.

7 . It is no secret that physical activity is necessary to a person’s well­being.Because children are continuously developing physically and emotionally，they are especially affected by the benefits of activity.Former First Lady Michelle Obama’s initiative “Let’s Move！” reports that nearly one­third of US children are overweight or obese，and that “schools are a key setting for kids to get their 60 minutes of play with moderate activity，given the significant portion(部分) of time they spend there.”

Physical education programs in schools directly benefit students’ physical health.Regular exercise promotes muscles and bone development.In addition to participating in physical activity，students in P. E.learn the fundamentals of a healthful lifestyle，the building blocks upon which they can develop into healthy，knowledgeable adults.

Though the lack of attention on P. E.is often justified as an opportunity to spend more time in the classroom，studies show that physical activity contributes to improved academic performance.Regular activity during the school day is strongly associated with higher concentration levels.A statewide policy in North Carolina requires that children from kindergarten to eighth grade participate in 30 minutes of physical activity each day.

Activities in P. E.help children develop healthful social interactions.From a young age，children learn cooperation through group activities and form a positive sense of identity as part of a team.Such group activities are continually important as children grow older.The International Platform on Sport and Development states that sport has been used as a practical tool to engage young people in their communities through volunteering，resulting in higher levels of leadership and community engagement among young people.

The benefits of P. E.to a child’s mental health are both complex and comprehensive.Improved physical health，academics and social interactions all contribute to good mental health.Physical activity sets the stage for a good night’s sleep，provides more energy to participate in hobbies and interact with others.

8 . Scientists have long known that humans are built for endurance. Now, a new study shows people's hearts are also bettered for endurance — though how much depends on whether we run, farm, or stay put on the sofa.

To get to the heart of the matter, researchers examined the hearts of more than 160 adult men from four groups: long-distance runners, sedentary adults, highly trained football player, and the Tarahumara, native American farmers famous for their running ability.

When researchers compared the thickest of the heart's ventricles, they found there were clear differences. Endurance runners and farmers had larger, longer ventricles with thin walls, which could help pump more blood for a long time, the researchers report today in the Proceedings of the National Academy of Sciences. The football player, whose training was short, high-intensity exercise, had shorter, wider ventricles with thicker walls. So did the sedentary humans.

Because high-intensity activity causes blood pressure to increase for a short amount of time, such shorter ventricle, thick walls, and rounder shapes are good for the football players, researchers say, by making sure enough blood is pumped to the brain. But even without those pressures, a couch potato lifestyle seems to result in the same kind of thickening.

But sedentary readers shouldn't feel heartbroken — the researchers said that changes in heart shape are likely reversible, with more endurance activities.

1. What was the aim of the research into hearts?

A．To work out why humans are built for endurance.

B．To make out what kind of ventricle is the healthiest.

C．To figure out whether hearts are bettered for sedentary adults.

D．To find out how endurance activities can make our hearts better.

2. Jimmy is a computer engineer who has to work for long hours on computer. Which of the following ventricle and walls may suit him according to the passage?

A．	B．
C．	D．

3. What will the passage talk about following the last paragraph?

A．Introduction to endurance activities.	B．Benefits of heart shape.
C．Damage happened to sedentary adults.	D．Diets on reversible health.

9 . If you have ever done competitive sports,you will know that starting a new season means a lot of hard work and practice.     1     Here are a few ways to make sure that you’re ready for the first day. 

    2     Ask your coach, gym teacher or trainer for some advice before writing your plan. Besides, write down how long you have worked out and what activity you have done. 

Ask your coach if you aren’t sure what you need. New equipment can be expensive, so think about using some second-hand equipment if it’s available. Brothers, sisters and friends can be great sources of used equipment.     3     You can ask your coach to take a look at it before the first day of practice. If you are a returning player, take out all your equipment, try it on and make sure that it still fits and works. 

    4     Sports camps can help new and experienced players brush up on skills before the season starts. College players, coaches or other professionals usually teach in the camps. Many schools and colleges offer various sports camps during the summer and on the weekend during the school year. 

Your school or team will probably require a physical check before allowing you to participate. Because everyone needs to get checked at the beginning of the season, doctors tend to be busy those times of the year. Therefore, set up an appointment with the doctor earlier.     5    

A．Set realistic goals.

B．You can also consider a sports camp.

C．Just make sure that it’s very clean and safe to use.

D．It’s also normal to feel a little nervous about starting.

E．Making the team and getting in shape are great goals.

F．Start by writing an exercise plan if you don’t have one.

G．That can give the doctor plenty of time to fill out your paperwork.

10 . Training “smart” is more important than the amount of daily practice.

Too often an athlete believes that the more he or she practices, the more proficient he/she will become.     1     It can also be harmful to achieving the desired outcome. An athlete who practices frequently and hard without an overall plan will be more likely to suffer the effects of overtraining rather than actually improving performance.     2     Yet, by developing a set of specific goals and a plan for reaching those goals, athletes can more effectively use their practice time and even reduce the time required in practice to attain their goals. Obviously, this does not mean that the martial artist can achieve rank or win tournaments with little practice.     3    

Setting performance goals is beneficial for a number of reasons.     4     When the martial artist is able to observe progress towards a goal on a daily or weekly basis, he or she is more likely to remain interested in achieving that goal. If instead, he/she engages in routine practice towards a belt rank that is six months away, it is easier to become discouraged. In addition, goal setting helps the athlete know what is expected which allows for greater attention to a particular skill that needs to be developed.     5     Finally, setting realistic, achievable goals increases the athlete’s self-confidence which is crucial to the ultimate outcome of success. Self-confidence increases because his/her attitude regarding success becomes more positive as goals are accomplished.

A．It is not always the case.

B．However, such training is ineffective.

C．It reduces boredom and increases motivation.

D．Thus, practice becomes more focused and efficient.

E．It means that the athlete does not need to waste time.

F．Firstly, it requires less patience and boosts confidence.

G．Typically, they will experience burn-out, exhaustion, and increased injuries.
