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 . One major reason Americans don’t get enough exercise is that they feel they don’t have enough time. It can be difficult to squeeze in the 75 minutes of aerobic (有氧的) exercise per week that federal guidelines recommend.    1    .

In a new analysis of 14 studies, researchers tracked deaths among more than 232,000 people from the U.S., Denmark, the U.K. and China over at least five years, and compared the findings with people’s self-reports about how much they ran. People who said they ran any amount were less likely to die than those who didn’t run at all.    2     This was true even for those who didn’t log a great deal of time. The analysis divided people into groups, with 50 minutes or less per week representing the group that ran the least―but still ran. ‘‘Regardless of how much you run, you can expect such benefits,” says Zeljko Pedisic, one of the authors of the new analysis published in the British Journal of Sports Medicine.

The analysis is the latest to illustrate the benefits of running on the human body. It’s what we evolved (进化) to do.     3     But as leisure-time exercise, running keeps us healthy. “One of the best ways to avoid having to see a doctor,” Zeljko says, “is to stay physically active.”

    4     Running is good at guarding against cancer partly because it uses up blood sugar, starving the cancer cells that rely on it for fuel. And it protects you in other ways not necessarily measured in the latest research: by decreasing inflammation (炎症), for example, which is at the root of many diseases, and stimulating the production of a protein that improves brain health.

    5     Neither were how often people ran and the pace they kept. As long as you’re running, more isn’t always better, especially given that the risk of injury increases with repetition.

A．People may no longer hunt wild animals for their next meal.

B．The physical demands of running affect our body in a beneficial way.

C．Some people run to prevent disease, and others run because it makes them feel better.

D．Runners were 27% less likely to die for any reason, compared with nonrunners.

E．But researchers point out, to infer something like that, they need the whole population measured.

F．But new research suggests people may be able to get life-lengthening benefits by running for far less time.

G．The good news is that running more than 50 minutes per week wasn’t linked to additional protections against dying.

4 . Why play games? Because they are fun, and a lot more besides. Following the rules, planning your next move and acting as a team member are all “game” ideas that you will come across throughout your life.

Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating .

Many children’s games have a practical side. Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones, which sharpens the hand-eye coordination (协调) needed in hunting.

Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.

Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it — some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to spread hope through soccer. He created a foundation to provide poor children with not only soccer balls but also a promising future.

Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life.

5 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your choice of sport might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses(高尔夫球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortages in some local areas.

In fact, there are many environment friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a pair of good shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk can regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and control your weight better.

Whatever sport you take up, you can make it greener by using environment friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements(代替物) for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

6 . Try This at Home!

Are you looking for a new pastime that will create a balance between physical activity and relaxation? Then yoga may be the perfect choice for you. Yoga can be practiced by people of all ages and levels of fitness.    1     It's a great way to strengthen your muscles and become more flexible.

In the 1930s, Indian Sri Tirumali and K. Pattabhi developed one of the most popular forms of yoga practised worldwide today. They worked together using an ancient Sansknt text called Yoga Korunta to create a set routine of yoga movements and breathing exercises.     2    

Ashtanga is different from other forms of yoga. It is a very powerful form of aerobic (有氧的)exercise which creates deep heat in the body.     3     In other forms of yoga, however, the routine can change each time and the stretching exercises aren't aerobic.

    4    As well as making you stronger and more flexible, it can also help you to stay calm. By focusing on your breathing while doing physical exercise, you are able to get a balance between mind and body. In addition, yoga helps to make us healthier so we are less likely to get common illnesses like colds.

Furthermore, yoga encourages you to think about what you're doing. Often you will close your eyes while doing certain movements.    5    After a few lessons you'll stop looking at what the others around you are doing. You will stop comparing yourself and start focusing on yourself.

A．It can also be done anywhere at any time.

B．The result of their co-operation was ashtanga yoga.

C．Whatever kind of yoga you choose, there are many long-term benefits.

D．This allows you to concentrate better and it makes you less competitive.

E．Every time someone practices ashtanga, he or she does exactly the same movements.

F．If you're interested in yoga, but can find a class near you, then it might be     an excuse to travel.

G．Recently, it has become extremely common for beginners as well as advanced yoga students to go on yoga holidays.

7 . Older women who walk a little over three kilometers each day might live longer than less active women of the same age, a new study suggests.

Many Americans hoping to stay healthy set a daily goal of 10, 000 steps, or about eight kilometers. They often have this goal because they are wearing electronic devices which set that target, note researchers in the United States. Their findings appeared recently in the publication JAMA Internal Medicine.

But it is not clear how much intensity(强度)or speed matter when counting the health benefits of every step, the researchers write. They add that 10,000 steps per day might not be the right goal for everyone.

For the study, researchers observed 17,000 women, all in their early 70s. They asked the women to wear accelerometers for at least four days. Accelerometers are small devices that measure the number of steps and the intensity of movement. The researchers followed up with the women much later, around 4. 3 years later, on average. Since the beginning of the study, 504 women had died. Compared to women who took no more than 2, 718 steps daily, the women who took at least 4,363 steps per day were 41 percent less likely to die.

“Even a modest amount of steps is associated with lower death rates, "said I-Min Lee, the lead writer of a report on the study. "The rate of stepping did not matter in these older women: it was the number of steps that mattered.

The study had a few limitations. For example, the researchers only measured women’s movements once, at the start of the study period. It is possible that the women’s behaviors changed over time. Still, the results are "good news for older adults who may have difficulty walking at faster paces, "said Keith Diaz, a researcher at Columbia University. He was not involved in the study.

“Any walking is better than nothing, " Diaz said by email. "With even small amounts of walking, your risk of death will be sharply reduced "For those who have difficulty walking, other research shows that any form of aerobic activity provides health benefits," he added. "Swimming, bicycling or any form of activity that is continuous in nature will provide health benefits.

A．People who walk about 10,000 steps can live longer.

B．10,000 steps per day might be the right goal for people.

C．The more steps one walks per day, the longer life he may live.

8 . For some people, walking or running outdoors is a great way to exercise. What may not be so great is seeing rubbish all over the ground. Well, some people are doing something about it.     1     “Plogging” began in Sweden. The name connects the Swedish word “plocka,” which means to pick up, and the word “jogging,” which means to run slowly.

A Swedish man named Erik Ahlström, started the movement in 2016. He moved to Stockholm from a small community (社区) in northern Sweden. Each day he would ride his bike to work. He became worried about the amount of rubbish and litter he saw each day on his way to work. So, he took matters into his own hands. He began picking up the rubbish.     2    

Today, plogging is an official activity, which is becoming more and more popular. People of all ages are welcome to plog. Exercise while helping your community.     3     It can also build closer social connections in a community. When the street looks bad and it’s dirty, you're going to feel bad about the community. You may even feel less safe because of that. So if we’re all doing our part and picking it up, it’s very easy to help beautify it, and help build those social connection.     4     You get to feel some social duty when you do this.

Along with cleaning up the environment, there may be another reason to choose plogging instead of just jogging. You may get a better workout. One fitness app, Lifesum, records one hour of plogging as burning 288 calories.     5    

As can be seen, cities around the world now hold plogging events. The goal is to spread the idea that littering is not acceptable. People would think twice before dropping a garbage on the ground.

A．Plogging is equal parts of exercise and community service.

B．And that is how plogging was born!

C．And plogging does good to your health.

D．Usual jogging burns about 235 calories.

E．They are plogging!

F．There are people all around the world doing this.

G．You get to know your neighbors.

10 . Before there was the written word, there was the language of dance. Dance expresses love and hate, joy and sorrow, life and death, and everything else in between.

    1    We dance from Florida to Alaska, from north to south and sea to sea. We dance at weddings, birthdays, office parties and just to fill the time.

“I adore dancing,” says Lester Bridges, the owner of a dance studio in Iowa. “I can’t imagine doing anything else with my life.” Bridges runs dance classes for all ages. “Teaching dance is wonderful.     2    It’s great to watch them. For many of them, it’s a way of meeting people and having a social life.”

    3    “I can tell you about one young couple,” says Bridges. “They’re learning to do traditional dances. They arrive at the class in low spirits and they leave with a smile.     4    ”

So, do we dance in order to make ourselves feel better, calmer, healthier? Andrea Hillier says, “Dance, like the pattern of a beating heart, is life. Even after all these years, I want to get better and better.    5     I find it hard to stop! Dancing reminds me I’m alive.”

A．So why do we dance?

B．Dance in the U.S. is everywhere.

C．If you like dancing outdoors, come to America.

D．My older students say it makes them feel young.

E．I keep practicing even when I’m extremely tired.

F．Dancing seems to change their feeling completely.

G．They stayed up all night long singing and dancing.
