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.

2 . The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.
Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said : "These findings are exciting because it’s possible that improving people's cardiovascular （心血管的）fitness in middle age could delay or even prevent them from developing dementia. "
For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak （最大值的） cardiovascular capacity. The average peak workload was measured at 103 watts.
A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.
These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.
"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.

3 . Common Mistakes New Runners Make
Running is a great way to get in shape and just about everyone can do it. However, many make a number of common mistakes, which can interfere (妨碍) with training or lead to injury.
·Doing too much too soon
One of the biggest mistakes new runners make is doing too much too soon. Slowly easing into a training program will help reduce the risk of injury, so you can continue on with your new running routine
·
Beginners might think they need to run every day (or nearly every day) to meet their fitness or weight-loss goals, but this couldn’t be further from the truth. Running is a high-impact activity which can be really hard on your body. So it’s important to give your body a rest between workouts.
·Not wearing the right equipment
•Running through pain
| A．Not taking rest days |
| B．If you’re just starting out |
| C．Comparing yourself to others |
| D．Running can be uncomfortable at times |

| G．Experts suggest increasing your running distance by no more than 10% each week |
The three-day torch relay for the Beijing Olympics, shortened considerably because of concerns about the coronavirus, started Wednesday with
The relay opened at the Olympics Foreign Park. Luo Zhihuan, the country’s first internationally competitive speed-skater,
The torch will be carried through the three Olympics zones, starting with downtown Beijing
The Beijing Games have already been impacted on a scale similar to that experienced by Tokyo during last year’s Summer Olympics. China says only selected spectators will be allowed to attend events, and Olympic athletes, officials, staff and journalists are required to stay within a bubble that keeps them from contact with the general public.
The truncated program seemed to have little effect on Luo, who after receiving the torch from Vice Premier Han Zheng said it was the realization of decades-long aspiration.
“I’ve never participated in the Winter Olympics, so I had hoped our country
The opening of the Beijing Games comes only days after the start of the Lunar New Year holiday, China’s biggest annual celebration
Participants in the torch relay have undergone health screenings and have been carefully monitored,
My dad and I had been looking forward to the Stale cross-country race of my senior year of high school, which would be the climax (顶点) of my existence.
I was the fastest runner on my team, and I was supposed to make it into the top fifteen. We had been working towards this race for three years. It was everything to me, and it was everything to my dad. He was a runner and was wild with joy by my success in running. He made it to every race, even flying home early from business trips to see me run. I always listened for his voice, which rang above the crowd-telling me to relax my arms, calling out my time. He pushed me. He cheered for me. He believed in me. We spent countless hours on the sandy canals of Arizona. Breathing in the dust of the desert, the blossoms of the orange trees, and the terrible smell of the dairy farm, we made our way across the city. We pounded miles and miles into our running shoes, marking with every step the path to greatness. It was a journey that was just ours. A dream passed on from one generation to the next.
Then the big day came. It was hotter than normal - too hot. My throat felt like a field of cotton, cracked with the summer heat, as I waited for the gun to fire. I gazed out at the crowd; dozens of familiar faces from church and school flickered across my view. They had come for me. They were counting on me. I saw my dad set his watch, worry and excitement etched across his face. With the sound of a gunshot, the race began.
For the first two and half miles, I felt great. I had never before been so ready for something. The weeks leading up to the race were filled with hard practices and a strict diet. The scorching sun beat upon my back, blinding me with its brilliance. Nothing was going to stop me, though.

People refer to never forgetting how to ride a bike or throw a baseball as examples of “muscle memory”, the result of a motor learning.
Previous research has shown that the changes actually persist in the muscles themselves. In one study of mice, the results suggest that after nuclei in muscle cells multiply in response to an overload of training, those extra nuclei aren’t lost during subsequent periods of inactivity. They are retained (保留), essentially waiting to be reactivated. If you fell off the fitness wagon (马车) during the pandemic, don’t be frustrated. Once you have got additional nuclei, you are banking the capacity.
Ultimately, muscle memory is a payoff for all the past work you put into learning a sport.
| A．The best way to tap into it is to “get back on the horse”. |
| B．Physiologists, on the other hand, define it in a different way. |
| C．This convinces the researchers that muscle memory may not be long lasting. |
| D．That is to say, we can do the sports automatically without conscious thought. |
| E．It is generally safe to increase these elements by 5 percent every week or two. |
| F．It is evident that the more you exercise, the more muscle memory savings you will have. |
| G．All this news about muscle memory is encouraging for those who fell off the fitness scheme. |
Ballet was a way of life in Kelly’s family. Her elder sister Serena was now dancing at a top college.Though Kelly’s mom always wanted her to follow in her sister’s footsteps and Kelly herself was good at ballet,her love for ballet had faded years before,and she was eager for a new challenge.
One day at school,as Kelly left the dance studio,she walked past the gym,fascinated by boxers(拳击手)training inside the boxing ring. She was deeply impressed by how hard they hit and how fast they moved. In fact, she’d long been attracted to boxing.
She pulled a piece of paper from her backpack.On the familiar Oakwood High School Club Sign-up Sheet was the phrase：BOXING CLUB TRYOUT(选拔).That was what Kelly really wanted to do.She knew her mom had high expectations for her when it came to ballet. Tired of trying to keep up with her sister, Kelly was ready to carve her own path.
The next day,she gathered her courage and told Serena about her new passion. At first, Serena didn’t understand and thought she was just joking. But when she saw Kelly was serious, she replied, “You know Mom wants you to be a ballet dancer,right? Besides, boxing is only for boys,and you’re so good at ballet.Lean into your strength,Kelly.”
“But this is where I want to put my strength,” Kelly insisted,“and what exactly does ‘only for boys’mean,anyway? Boxing is a sport for everyone!”
Gradually,touched by her determination and passion, Serena began to understand and support her.Kelly could feel it. Her sister was going to respect her decision,no matter what.But that was nothing compared to the preparations for the tryout,where she was required to show her footwork and punching(击打)abilities with other candidates. Boxing didn＇t come natural to Kelly,but she had made up her mind to stick with her choice.

The frightening day of our diving test was here. Our parents thought we were lucky to have an Olympic-size swimming pool at the school. My mom stressed that the swimming pool was one of the best in our city. But I didn’t feel happy about it at all. Instead, I felt afraid of the swimming pool. It was mainly because I was terribly shy.
I was so shy that I always sat at the back of the room in class so I’d not be called upon to read. As for the present physical education class each Monday morning, I would work my way to the back of the line forming at the diving board so I would not have to practice the dives.
Now, it was another Monday morning - the morning of our diving test. My blood ran cold when the teacher Ms. Robbins announced that we would be graded for our final on the most difficult dive- the jackknife. And she added, “This diving test is important. The one who fails has to spare time in the following Monday mornings to practice diving in this swimming pool and attend this test again.”
My body kept shaking with fear as the line to the scary diving board shortened. As I watched, each student seemed to perform the challenging dive effortlessly. And shortly I would have to attempt something that I had never even practiced before.
Then I remembered someone telling me that when you picture yourself doing a skill over and over, it’s just as effective as physically practicing that skill. So I watched carefully as each classmate jumped at the end of the board once, added a jump for height, folded their body in half to reach for their toes, and finally straightened out like an arrow for going into the water. After carefully watching for a while, I was actually in a state of surprise, because all of a sudden I realized that it was possible for me to perform these four steps of diving.
Eventually all classmates except me finished jumping. The teacher announced that it was my turn.
