Race walking (竞走) shares many fitness benefits with running, research shows, while most likely leading 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 (摆动) and one foot remain in contact 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. Race walkers moving at a pace of six miles per hour would burn about 800 calories (卡路里) hour, which is almost 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 doesn’t do as much harm to the body 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 (咨询) a coach or experienced racer to learn proper technique, she says. It takes some practice.

【推荐1】Running is the best way to get fit.
There’s no best method to get fit. You have to enjoy your exercise or you will find reasons to quit. Nobody can get fit or lose weight or build a muscle in an instant. Fitness requires time and patience, and you get rewards as you go along. If you are looking only at running or at instant success, you are looking for trouble!
If you don’t exercise an hour a day, six days a week, you do nothing.
Don’t believe in this all-or-nothing way. Even if you exercise as little as three times a week for half an hour you will benefit from it. However, if you want to get fit for sport, you may have to work out five to six days a week.
Warming up before working out isn’t necessary if you’re careful.
Warming up is a must before you exercise. Warming up and stretching not only help you avoid injuries but also prepare your heart and body to accept the shock of an increased workload.
No pain, no gain.
Pain means that the body is showing that there is something wrong. If you feel painful when exercising, either slow down or stop the exercise. To gain from exercise, you may have to make do with a bit of discomfort, but pain is different. If you continue exercising with pain you may damage a muscle or tendon forever.
Taping (用绷带包扎) an injury prevents further damage.
If you are injured and you tape it for support, chances are that you will aggravate the injury further. What’s more, you may injure other joints because of the limited flexibility (灵活性) that the taped knee or ankle allows.

【推荐1】A study showed that the experiences children have in their first few years are important. These experiences affect the development of the brain. When children receive more attention, they often have higher IQs. Babies receive information when they see, hear and feel things, which makes connections between different parts of the brain. There are a hundred trillion(万亿) connections in the brain of a three-year-old child.
Researcher Judit Gervain tested how good newborns are at distinguishing different sound patterns. Her researchers produced images of the brains of babies as they heard different sound patterns. For example, one order was mu-ba-ba. This is the pattern “A-B-B”. Another order was mu-ba-ge. This is the pattern “A-B-C”. The images showed that the part of the brain responsible for speech was more active during the “A-B-B” pattern. This shows that babies can tell the difference between different patterns. They also were sensitive to where it occurred in the order.
Gervain is excited by these findings because the order of sounds is the building block of words and grammar. “Position is key to language,” she says. “If something is at the beginning or at the end, it makes a big difference: ‘John caught the bear.’ is very different from ‘The bear caught John.’”
Researchers led by scientist Patricia Kuhl have found that language delivered by televisions, audio books, the Internet, or smartphones—no matter how educational—doesn’t appear to be enough for children’s brain development. They carried out a study of nine-month-old American babies. They expected the first group who’d watched videos in Chinese to show the same kind of learning as the second group who were brought face-to-face with the same sounds. Instead they found a huge difference. The babies in the second group were able to distinguish between similar Chinese sounds as well as native listeners. But the other babies—regardless of whether they had watched the video or listened to the audio—learned nothing.
1. What makes connections in a baby’s brain?A.Having a higher IQ. |
B.Experiencing new information. |
C.The baby’s early age. |
D.The connection with other babies. |
A.Babies can identify different sound patterns. |
B.Word order is relevant to meaning. |

【推荐2】I’m Gu Ailing Eilleen, a professional freeskier, and twin-tipped skis, 22-foot halfpipes (U型滑道) and double-cork rotations are my main sources of adrenaline (肾上腺素), the truly addictive core of extreme sports.
Though it’s easy to label extreme sport athletes as fearless, the countless hours I’ve spent visualizing tricks and practicing them in foam pits and on airbags suggest otherwise. Instead of ignoring fear, we build unique relationships with it.
The work begins with visualization. I take a deep breath and close my eyes. As I go up the huge takeoff slope, I imagine extending my legs to maximize lift. Then I picture twisting my upper body in the opposite direction I intend to spin, generating force before I allow it to move back the other way.
1440 degrees. I smile. Then I open my eyes.
It doesn’t take much, unfortunately, for uncertainty to override confidence. Imperfect preparation moistens my palms and makes each breath shallower than the last. The feeling isn’t panic, but something like dread. Danger! cries every evolutionary instinct. Every freeskier’s goal is to recognize the minute differences between excitement and uncertainty in order to maximize performance while minimizing the risk of injury.
Finally, there’s pressure, an energy source that can be employed in many ways. I’m proud of the work I’ve done to cope with pressure by improving my self-esteem and minimizing my need for external validation. No matter how much time passes, I’ll always be a hopeless romantic when it comes to fear.
1. According to Gu, what mainly makes athletes fall in love with extreme sports?A.The honor she will obtain if they win a match. |
B.The athletes social status will be improved after winning. |
C.The money they will be rewarded in the case of winning. |
D.The athletes experience the feeling of excitement during the sport. |
A.They are born fearless. | B.They overcome fear by practice. |
C.They are forced to be fearless. | D.They just ignore fear. |
A.break | B.improve | C.unfold | D.wet |
A.Gu Ailing is on the way to success. | B.I admit it, I am in love with fear. |
C.How Gu Ailing overcomes her fear. | D.All success comes from hard work. |
【推荐3】We have some excellent online films to recommend to you to kill boring time during the lockdown period.
Spider-Man: No Way Home
Rating: 8. 0 December
Now that Marvel’s superheroes have saved the Universe, their next job is obvious: They have to save the multiverse. In the third of the Spider-Man starring Tom Holland, the teenage web-spinner accidentally opens a gate to numerous parallel realities. “What people will be really surprised about is that it’s not fun. “Holland told Total Film. “It’s dark and it’s sad, and it’s going to be really affecting.”
Dune
Rating: 7. 8 October
Now at last we have a big-screen Dune that may actually do justice to Frank Herbert’s science-fiction novel. Directed by Denis Villeneuve, this film runs for 155 minutes and still only covers the first half of the book. As space operas about psychic-powered young heroes on desert planets go, it may never be as popular as Star Wars.
Ron’s Gone Wrong
Rating: 7. 7 October
Ron’s Gone Wrong, the first feature-length cartoon from a new British studio. Locksmith Animation, is a family comedy about the differences between social media and physical interaction. Its schoolboy hero, Barney, is given what seems to be the ideal toy, a shiny robot which is programmed to be his friend-assuming it works properly. The problem is that this particular robot, Ron, barely works at all. What do you expect to happen between them?

Lee Isaac Chung’s autobiographical drama has had faithful reviews. Most of the dialogues are in Korean, so the organizers of the Golden Globes put it in the Foreign Language Film category. Glenn Whipp in the Los Angeles Times says that the film “feels like a balm (镇痛软膏) right now, a gentle, truthful and tender story of family filled with kind people trying to love one another the best they can.”
