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 the50-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. 28．Why are race walkers conditioned athletes?A．They must run long distances.B．They are qualified for the marathon.C．They have to follow special rules.D．They are good at swinging their legs.29．What advantage does race walking have over running?A．It’s more popular at the Olympics.B．It’s less challenging physically.C．It’s more effective in body building.D．It’s less likely to cause knee injuries.30．What is Dr. Norberg’s suggestion for someone trying race walking?A．Getting experts’ opinions.B．Having a medical checkup.C．Hiring an experienced coach.D．Doing regular exercises.31．Which word best describes the author’s attitude to race walking?A．Skeptical.B．Objective.C．Tolerant.D．Conservative.【答案】28．C29．D30．A31．B【解析】这是一篇说明文。

Unit 2 The Olympic Games Period 2 Reading课后阅读训练Ⅰ.阅读理解AThe Olympic Games are the greatest festival of sport in the world.Every four years, a hundred or more countries send their best sportsmen to compete for the highest honours in sports. As many as 6,000 people takepart in over 20 sports. For the winners, there are gold medals and glory. But there is honour, too, for all who compete, win or lose. That is in thespirit of the Olympics—to take part is what matters.The Olympic Games always start in a bright color and action. The teams of all the nations parade in the opening ceremony and march round the track. The custom is for the Greek team to march in first. For it was in Greece that the Olympics began. The team of the country where the Games are being held—the host country— marches in last.The runner with the Olympic torch then enters the stadium and lights the flame. A sportsman from the host country takes the Olympic oath(宣誓)on behalf of all the competitors. The judges and officials also take an oath. After the sportsmen march out of the stadium, the host country puts on a wonderful display.The competitions begin the next day. There are usually more than twenty sports in the Games. The rule is that there must be at least fifteen. The main events are in track and field, but it is a few days before these sports start. Each day the competitors take part in a different sport—riding, shooting, swimming, and cross-country running. Points are gained for each event. Medals are awarded for the individual winners and for national teams.More and more women are taking part in the Games. They first competed in 1900,in tennis and golf. 【语篇概述】本文主要讲夏季奥运会的情况,包括运动员、裁判、开幕式、各大项目等。

Dancing to heal the body“空中课堂”舞动“云上芭蕾”。

On a recent Thursday morning, at home and facing a tiny camera, Orlando Ballet dancer Adam Boreland practices in quarantine (隔离), while his students watch his moves.Boreland’s online ballet class is one aspect of the partnership between the Orange County school district and major Central Florida arts organizations. It is a partnership that has taken new directions ever since the coronavirus shut down local schools.Other “distance learning” arts instruction comes from Orlando Repertory Theatre, Opera Orlando, Orlando Museum of Art and the Orlando Philharmonic Orchestra.The Repertory Theatre designs workshops for theater students, such as how to design sets at home, and then reviews the results. The Philharmonic’s musicians are providing individual instrument lessons to students in low-income areas, while theopera company is leading master classes (大师讲堂) for choral students and teaching performance tips. The art museum creates educational programming for both elementary and secondary students.Across the district, roughly 5,900 students study dance in about 25 programs, according to Scott Evans, director of the school district’s fine arts curriculum. The goal is to let as many as possible attend an Orlando Ballet class.Boreland’s class includes students from Apopka, Freedom, University, Wekiva and Windermere High, as well as Timber Creek. “We’re stuck inside. You really want to emote and heal the body through dance,” Boreland tells them.He also gives online dance feedback. “Keep the foot connected to the floor,” he says. “Don’t change the hips; save it for hip-hop class.”Sophomore Alessandra Lozzi, a two-year member of the Timber Creek dance team, appreciates the chance to “soak up (吸收) information” from Boreland. “His technique, his passion for dancing ... I love it,” she said.The instruction and interaction help the ballet company with its mission of reaching out to the community, said Orlando Ballet School director Phillip Broomhead.“It’s tremendous (绝妙的) that we are able to collaborate,” he said. “It’s giving the students a glimpse of people living the dream right now.”Boreland’s class ends with students’ thank-you comments flooding the online chat window.Lozzi, who hopes to dance professionally one day, can’t wait for another session. “It’s inspiring,” she said.（选自Reader’s Digest）1.

Do big sporting events make us do more sport?大型体育赛事真的会促使我们做更多的运动吗？I recently spent half aweekend sitting on the sofa watchingthe Davis Cup. I thought about goingfor a run, but I did not want to miss therest of the match. Soon it was startingto get dark, so I did not bother.Whenever I watch tennis, I think hownice it would be to play it regularly.But I have been thinking that for almost 20 years without actually setting foot on a court. The evidence would suggest that I’m not the only one.When a country or city bids to host an international sporting event, it often promises that more people will take up sports as a result. London was no exception. Tessa Jowell, who helped to secure the 2012 Olympics for London, said they would be the first to set challenging but achievable targets as a measure of their ambition: By 2012 two million more people would be physically active. And 60 percent of young people would be doing at least five hours of sports per week.In the end it did not turn out quite like that. Just over one-third of people in Britain take part in sports once a week. A report on Olympic and Paralympic legacy has said that a big change in participation levels simply has not happened.Why isn’t there a big increase in people taking part in sports after most sporting events? Perhaps it is a mistake to assume an automatic link between watching sports and playing it. While the games are on, they actually encourage people to do just the opposite — to spend whole sunny days not out playing sports, but inside sitting on the sofa with the curtains shut to stop the sun shining on the TV screen and spoiling the view. We don’t expect half the audience of a hit musical to apply to drama school the next day, yet we seem to expect it of sporting events.We might have sat on the sofa doing an impression of Usain Bolt’s bow-and-arrow signature pose. But how many of us have been inspired by watching him sprint（短跑）100 meters? The high-level performances on show only remind people that they could never match the elite athletes in their sporting achievements even if they trained full time.Maybe participation in sports is not the right legacy to expect after a major sporting event. It’s not so much that the Olympics failed to get people to participate but rather that this was never going to be the result. The Olympics can do many things, but maybe this cannot necessarily be one of them.（节选自BBC）1. What can we learn from the first paragraph?A. The author prefers playing tennis to running.B. The author watches tennis matches very rarely.C. The author hasn’t played tennis in nearly two decades.D. The author didn’t go for a run because the match lasted longer than expected.2. The underlined word “secure” in Paragraph 2 probably means “_________A. to fastenB.to protectC. to obtainD. to promise3. According to the article, there is no noticeable rise in sport participation after most events because .①it takes people a longer time to play sports than watch it②watching sports actually discourages people from going out③sporting events make people aware that they could never be as good as elite athletes④people are too busy to get into the habit of taking part in sportsA.①②B.②③C.③④D.①④4. According to the author, to expect more citizens to play sports after a country hosts the Olympics is .A. importantB. naturalC. harmfulD. unnecessary词汇：bother v. to make the effort to do sth. 费心，麻烦evidence n. facts or signs that show clearly that sth. exists or is true.证据，证明legacy n. sth. that happens or exists as a result of things that happens at an earlier time.遗留物语法：It’s not so much that the Olympics failed to get people to participate but rather that this was never going to be the result.not so much as ...as...是一个固定短语，意为“与其说是...不如说是...”。

运动是好事英文作文英文：Sports is definitely a good thing. Not only does it keep you physically fit, but it also has a positive impact on your mental health. Personally, I love playing basketball. Whenever I feel stressed or anxious, playing a game of basketball helps me release all that negative energy. It's a great way to clear my mind and focus on something positive. 。

In addition to the mental benefits, sports also has social benefits. Playing on a team or joining a sports club can help you meet new people and make friends who share the same interests as you. It's a great way to build a sense of community and belonging. 。

Furthermore, participating in sports can also teach you important life skills such as teamwork, leadership, and perseverance. These skills can be applied not only insports but also in your personal and professional life. For example, I learned how to be a team player when I played on my high school basketball team. This skill has helped me in group projects in college and in my current job. 。
