According to a review of evidence in a medical journal, runners live three years     1    (long) than non-runners. You don't have to run fast or for long    2    (see)the benefit. You may drink, smoke, be overweight and still reduce your risk of     3     (die) early by running. While running regularly can't make you live forever, the review says it     4     (be) more effective at lengthening life    5     walking, cycling or swimming. Two of the authors of the review also made a study published in 2014    6    showed a mere five to 10 minutes A day of running reduced the risk of heart disease and early deaths from all     7    (cause).

The best exercise is one that you enjoy and will do. But otherwise…   it's probably running. To avoid knee pain, you can run on soft surfaces, do exercises to    8    (strength)your leg muscles(肌肉),avoid hills and get good running shoes. Running is cheap, easy and it's always    9    (energy).If you are time poor, you need run for only half the time to get the same benefits as other sports, so perhaps we should all give    10    a try.

Up to 82 percent of children with healthy mothers are not easy to be obese（肥胖的）, according to research. A mother,     1     has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke and only     2    (drink) wine in moderation, is significantly less likely     3    (have)a fat child, scientists say.

And research suggests it could be more to do with nurture(养育)    4     nature, as a mother's lifestyle appears     5    (direct) linked to the health of her child. When both mother and child follow a healthy lifestyle, the risk of obesity     6    (reduce)even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged nine     7     fourteen, born to almost 17,000 women in the US. Researchers looked at the link between overall mother health and likelihood of a child     8    (be) obese.

The mother's health was judged on her height-to-weight ratio(比例), her diet, amount of physical     9    (active), smoking status and how much alcohol she drank. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having     10     obese child.

There’s no doubt that doing more exercise is     1    (help) to us. As students, we can make     2    (we) more active and smarter by doing exercise in our daily life.

    3    (person), I think highly of jogging because it’s good for health. Take myself    4    example, I often jog in the playground for half     5     hour. Each time I finish it, I feel my body has been     6    (strength).

It’s helpful for us to do more exercise. I     7     hope that everyone does some sports in their spare time rather     8     just stay at home     9     bury themselves in their work.

Let’s go out    10    (do) more exercise!

What do the five Olympic signs on the flag represent?     1     is widely believed that the five-riing Olympic symbol was created by Frenchman Pierre De Coubertin in 1913. As the founder of the modern Olympic Games, he wanted     2    (celebrate) the 20the anniversary(周年纪念) of the Games and chose a design of five rings,     3     represented the five continents(洲) taking part in the Games. The rings     4    (become) the official Olympic symbol at the 1920 Games in Belgium.

Pierre de Coubertin thought that the five interlocking rings meant the five continents     5    (compete) in the Games and the meeting of their athletes at the Olympic games.     6    (actual) every part of the modern Olympic symbol and flag shows the main purpose of the Games in a particular way. The Olympic flag, with its familiar rings, is used as     7     international symbol of peace, unity and     8    (agree). The white background of the flag stands     9     peace and truth.

At the end of each Olympic Games, the mayor(市长) of the hosting city passes the Olympic fag to the mayor of the city where the next Olympics     10    (hold) for years later. The flag remains there until the next Olympics.

Last October I left the UK behind and joined Gillotts School on their rugby and hockey tour in sunny Italy. It was my first time away on a sports tour and I could not have enjoyed it     1     (much)! Five days of sports, between training and matches with Italian players, but also plenty     2    time for sightseeing and free moments to enjoy an ice cream in the sun.

    3     our flight had landed in Milan, we got on our coach and drove for a couple of hours towards our home for the week, the Hotel San Zeno, a     4     (comfort), family-run accommodation, with a splendid view of Lake Garda. Starting the day with a self-led training, enjoying a boat tour on the lake, wandering along the streets of Sirmione for a few hours and heading off     5     (play) a sport — these are just a few     6     (example) of the kind of adventures you could be having!

The girls and boys on this tour seemed to enjoy    7     (they) thoroughly, especially after winning ALL of their games! I found myself     8     (cheer) them on like a proud aunt and celebrating afterwards with food, drink and social time, hosted by rugby clubs after matches. On the last day we headed back to     9     airport, but not before stopping in Milan! We     10     (pay) a visit to the San Siro museum and enjoyed a stadium tour before moving on to Milan city centre for an afternoon of shopping.

For 34 years, thousands of runners     1    （take）on the Marathon des Sables, a 140-mile race through the Sahara.     2    (consider) the world’s most difficult race, des Sables takes place over the course of six days through Morocco’s unforgiving Sahara.

At 46, Amy Palmiero-Winter is not what most picture when they think of     3     athlete, but for her, running has been a lifelong passion: an escape, a comfort, a calling. So, when a careless driver crashed into her motorcycle 25 years ago and damaged her left leg, she did everything she could     4    （save）it.

She couldn’t imagine not running. But three years and 25 operations later it became obvious that her leg would never     5    （true）recover. But hardships couldn’t keep her from running. In fact, they may have pushed her     6    （close）towards it. “When something bad happened to me, I went out for a run. It kept me from any darkness.” Palmiero-Winter said. After recovering from her amputation, she tried running again. Struggling     7    low-tech artificial legs, in 2004 she placed second in the Silver Strand Half Marathon. Today, she holds 11 world records and countless awards,     8    （include）the James E. Sullivan Award and others,     9    recognized her as the world’s top amateur athlete nearly a decade ago.

But as her latest     10    （achieve）at the Marathon des Sables shows, she’s nowhere near done.

Life is often a matter of waiting for the right moment to act. Sun Yang was the first Chinese man     1     (win) an Olympic gold medal in swimming. That moment     2     (come) last month, when he won the men’s 200-meter freestyle event at the Asian Games.

Sun has accomplished a Golden Grand Slam, having won the 200, 400 and 1, 500-meter freestyle events at the Asian Games, World Championships and Olympic Games. His     3     (patient) and persistence have paid off. The 26-year-old swimmer told Xinhua News Agency, “Not many swimmers could have waited for eight years over three Asian Games like me. My dream has     4     (final) come true.”

While Sun stood on a podium (领奖台)     5     (listen) to the Chinese national anthem (国歌) along with the silver and bronze medal winners, a technical problem caused the medalists’ flags to drop to the ground. Sun jumped off the podium, walked over to the officials and demanded that the flags again.     6     the end, the officials held the flags up themselves as China’s national anthem played a second time.

Many Chinese Internet users thought Suns reaction to the incident to be an act of patriotism (爱国主义). “    7     is great to win the championship, but    8    (see) our national flag go up again is also very important. Winning the title is an achievement     9     will be remembered, but raising the flag again is also of great     10     (important).”

In the field of sports there are some famous living legends, such as Lang Ping, and Michael Jordan.

As a player, Lang Ping brought not only honour but also glory to     1     (she) country. As     2     coach, she led the China Women’s volleyball team to medals at world championships as well as the Olympic Games. As a person, she is     3     (love) by fans at home and abroad. Before the 2015 World Cup, she     4     (face) a great challenge — two important     5     (player) had to leave because of health problems. However, Lang Ping didn’t lose heart and she led her volleyball team     6     (win) the championship.

Known as “Air Jordan”, Michael Jordan changed basketball with his graceful moves and jumps. Jordan’s skills were impressive but the mental strength     7     (make) him unique. The secret to his success is learning     8     his failures. In life, Jordan has learnt to share his     9     (succeed) with others. The Boys and Girls Club     10     he started in Chicago has been helping young people since 1996.

As is     1     (know) to all, the Olympic Games are the most important events in the world. They were first held in ancient Greece     2     776 BC. And the events were named after the city Olympia. Slaves and women could not be allowed to take part in the ancient Olympics, and the     3     (athlete) were all from the same country.

In 1896,     4     first modern Olympics opened in Athens, the capital city of Greece. From then on, the Olympic Games     5     (take) place every four years. Athletes from the whole world can take part in the     6     (importance) events, whether they are men or women. The five rings on the Olympic Flag stand     7     five continents and the union of the whole world.

China didn't become a member of the modern Olympics until the 1950s. And in 1984, Xu Haifeng became the first Chinese that won an Olympic gold medal in shooting. With the     8     (develop) of China, Beijing finally succeeded in     9     (hold) the 2008 Olympics, during which the five Fuwa mascots     10     (deep) impressed the whole world.

Olympic and Paralympic medals for the Tokyo 2020 Games will be made from recycled mobile phones donated by the public.

Olympic host cities have     1     (tradition) obtained the metal from mining firms. But Japan,     2     lacks its own mineral resources, is keen on taking the theme of a sustainable future a step     3     (far).

“A project which allows the people of Japan     4     (participate) in creating the medals is really good, and helps raise the environmental awareness of our citizens,” said Tokyo 2020 sports     5     (direct) Koji Murofushi. “    6     the resources of our earth are limited, we need to recycle more and avoid waste. This program is setting an example ”

Collection boxes have been placed in local offices and telecom stores and they will remain there until the metal required     7     (collect).

Members of the organizing committee put forward the idea    8     government officials and companies earlier this year and won their support.

As a result, the medals hanging around Olympic winners’ necks will carry even more meaning than usual. People’s personal memories, once     9     (store) in their smartphones and other handheld devices, will take the round shape of an Olympic medal, one of the most precious     10     (prize) in sport.
