1 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

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.

4 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.

But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.

According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.

To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.

“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.

Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.

It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

1. What did scientists from German universities recently discover?

A．Working out is a highly effective way to treat depression.

B．The runner’s high could be caused by endocannabinoids.

C．Endorphins may contribute to one’s high spirits after running.

D．The level of endorphins and endocannabinoids could affect one’s mood.

2. Why did the scientists give mice drugs in their experiment?

A．To find what reduces the runner’s high symptoms.

B．To see the specific symptoms of the runner’s high.

C．To identify what is responsible for the runner’s high.

D．To test what influences the level of endocannabinoids released.

3. What does the underlined word “notion” mean?

A．Effect.

B．Goal.

C．Opinion.

D．Question

4. What can we know about regular workouts according to the UK’s National Health Service?

A．They can help ease depression symptoms.

B．They are the best way to treat depression.

Mary waited anxiously for her turn in the empty dressing room. Never had she been so nervous before. This competition was of vital importance to her comeback. “If I can win today,” she said to herself, “I can dance on the national stage next month.” Three months ago, her left arm was seriously injured in a car accident. After the medical treatment, she began to recover slowly. She practiced over and over again in order to regain her dancing skills.

“Hi, Mary,” in rushed her friend Jessica “How is your arm? Is it going to influence your performance?”

“I guess it can be tolerated for I am to win the match.” said Mary with a determined look.

“Admirable! But I hear that a girl called Linda is really gifted and strong. She can be your real well-matched competitor. Come on!”

After Jessica left, Mary decided to practice her most difficult spin. “If I don’t try harder, I won’t grasp this chance.” She thought. But her arm began to hurt, making her worried. “Mary, what makes you think you have a chance tonight?” she said to herself. After the pain was gone, she continued to warm up.

A slim girl hurried in and put down an equipment bag on the chair. Then, she took out her dance dress quickly and put it on skillfully. Seeing Mary, she smiled politely and said “Hi, I’m Linda. I am the next one!” Mary nodded in reply but felt uncomfortable. “This is just my competitor. Because of her, I may lose tonight.” Her mind was wandering when Linda let out a scream, “Oh, God, I can’t find my music tape!” Linda searched her bag but in vain. “It may be missing on the way.” With these words, she then rushed out.

9 . There are many ways to travel within a city. We can walk, cycle, or take a bus. But no matter which way we travel, we have to follow the route (线路) the city planners laid down for us.

Parkour practitioners (跑酷爱好者), however, see the city in a completely different way. To them, there are no designed routes. There are no walls and no stairs — they jump, climb, roll and crawl to move across, through, over and under anything that they find in their path. The city is their playground.

The International Gymnastics Federation (FIG) has noticed that this activity is drawing more and more people to it — there are 100, 000 people taking part in parkour today in the UK alone, according to The Guardian — and how it is helpful for people to be much stronger: It trains coordination and balance. So the FIG is thinking about recognizing parkour as a new sport and adding it to the Olympics by 2024.

But parkour practitioners themselves don’t seem to be happy with the idea. They see parkour as “a lifestyle”, wrote the website NextSportStar. “It’s a competition against the conditions rather than just a sport.”

Indeed, many do parkour just to “escape the daily routine and experience the city in different ways”, wrote reporter Oli Mould on The Conversation. They see parkour as a way to express themselves through relaxing moves and creative routes while freeing themselves from the pressure.

It’s great that the FIG wants to develop a new sport and stay close to a new cultural form. But it would be greater if they knew that not everything in life is a competition.

1. How do the parkour practitioners do parkour?

A．They plan the way themselves.

B．They move on as they wish.

C．They run faster than others.

D．They follow certain routes.

2. Why does the FIG want to add parkour to the Olympics?

A．It’s a special way of life.

B．It draws their attention.

C．It helps balance people’s life.

D．It’s good for people to keep healthy.

3. What is the author’s idea on parkour?

A．It is more exciting than other sports.

B．It is worth adding to the sporting event.

C．It is more a lifestyle than a competition.

D．It encourages people to challenge themselves.

4. What is the best title for the passage?

A．Parkour practitioners

B．Making the city their own

C．Training in a different way

D．A new sports competition

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

Watching sport might have some positive consequences.     2    (support) a team can give people a sense of community and boost fans’ self-esteem when their team wins. Jason Lanter is a psychology professor at Kutztown University who studies the    3    (behave) of sport fans. Lanter said people feel like they fit in. They know there     4    （be）good psychological and also health benefits simply from being part of a group.

On the other hand, however, when watching    5    intense match like the World Cup, people’s pulses can     6    (easy) spike (激增) which could cause heart attacks, especially when their teams lose. On the day in 1998 when Argentina defeated England in the World Cup, 55 more people     7    (admit) to hospitals due to heart attacks,     8    (compare) to an average day in England. British research revealed that apart     9    heart attacks, the excitement, disappointment and flow of adrenalin from watching a national team play might also cause more domestic violence.

John Ryan, a cardiologist at the University of Utah Health Care advised people to stay hydrated, stay cool and eat and drink alcohol in moderation. He said those same pieces of advice     10    we find useful for life in general are also useful while we’re watching sport games.
