1 . The reasons skiers and snowboarders wear goggles or glasses might seem a little obvious, especially if you’ve ever hit the slopes yourself. Sunlight reflected off the snow can make it hard to see, and UV rays can even damage your eyesight. Special colored lenses also create contrast, so your whole path won’t look like one flat expanse of whiteness.    1    

Olympic speed skaters, meanwhile, are racing inside on smooth ice.     2    

According to NBC Olympics, glasses can increase visibility on indoor tracks, too.     3     And while the ice may look smooth from a distance, those sharp blades can kick up ice chips that could pose problems if they end up in your eyes. In the event of a crash, shatter-proof glasses also protect skaters’ eyes from errant blades and body parts.

    4     Shot-track speed skaters (who race around a roughly 11-meter track) can go as fast as 30 miles per hour or more, and long-track speed skaters (whose track is 400 meters long) sometimes hit about 35 miles per hour. The wind resistance generated by such speed- in a chilly arena—is enough to make any skater’s eyes start streaming with tears. Picture leaning your head out the window of a car that’s going around 35 miles per hour on a cold day: You’d probably want to be wearing glasses, too.

That said, glasses aren’t a requirement.     5     Belgium’s Stijn Desmet, for example, has raced in Beijing 2022 Olympic Winter Games without eyewear, as has China’s Zhang Chutong.

A．How do they wear glasses?

B．So why do they wear glasses?

C．Some skiers are afraid of the sunlight.

D．Some skaters’ lenses are tinted to help with that.

E．You’ll occasionally see speed skaters with uncovered visages.

F．Not to mention that eyewear shields your eyes from any snow you displace.

G．But the biggest reason speed skaters opt for eyewear just might be their speed.

2 . Want to add a simple movement to your daily life? Walking may be your best choice.    1    .

Walking is good for your heart

Walking is considered as cardio（有氧的）exercise, no matter the speed at which you take it. Studies show that walking can reduce the risk of heart disease and lower your resting heart rate and blood pressure.    2    . You can go for a 30-minute walk once a day or break it up into three 10-minute parts.

    3    

What benefits physical health often benefits mental health-the same is true for walking. Just five minutes of walking can lower anxiety. If you have any kind of green space nearby, try to take advantage of it. One study showed that people who went on a 90-minute nature walk reported fewer bad feelings.

Walking can improve your sleep

    4    . Getting outside in the day for a walk can also help you stay awake in the morning and get sleepier toward the night. If a nighttime walk is your preference, experts suggest you finish it three hours before bedtime.

Walking can help with fat loss

Walking is a type of cardio workout that is good for fat loss and can help you achieve or keep a healthy weight. It should be done regularly and for long periods of time.    5    . A brisk（轻快的）pace refers to a 17-to 15-minute mile, or 50%to 70%of your maximum heart rate.

A．Walking can help reduce stress

B．That can help you sleep easily during the day

C．Here are some of the benefits walking offers you

D．Walking in the day can help you get a better night's rest

E．Good walking can also keep your head up and looking ahead

F．Experts suggest walking 30 minutes a day, five to seven days a week

G．Walking at least 45 minutes a day at a brisk pace will see the most benefits

3 . On a bright Sunday at the Westmoreland Park pond (池塘) in Portland, Oregon, USA, boats are lining up for something special.

A loud voice comes out of the loudspeaker, welcoming everyone to the yearly Milk Carton Boat Race. The event has been part of the Portland Rose Festival, a popular event that brings Oregonians together, since 1973. Teams excitedly compete for the People’s Choice Award.

Adam Baker, whose organization supports the event each year, says that this is an important race for all of Oregon, especially Portland.

“This is a community event where we can get people to plan how to build special boats—made with used milk containers (容器), to think long-term on how to build a better boat, how to collect materials, and get everybody working together,” says Baker. “You can have single riders, grown-ups, youths, mixed ages. There's engineering. There’s teamwork.”Colton Snook has been taking part in the Milk Carton Boat Race for 10 years. “It’s our family tradition in the summer,” he says, Colton and his boat, “Chocolate Thunder,” end up winning first place in the grown-up races — and not for the first time.

When the youth teams line up, there is a boat that looks just like a beloved movie character—Lightning McQueen from Pixar, s Cars. Connor, the 8-year-old captain, rows across the pond for the first time at high speed and finishes second.

Connor and his family built the boat together, making a wood frame (框架) first and then adding milk boxes to increase its ability to float. He says that Cars inspired the building and designing of his boat: “I really like the movie.”

The event ends with a warm goodbye from Adam Baker and a promise to be back next year.

4 . Chinese students are showing their enthusiasm and innovative thinking about mobile applications in coming up with a series of innovative apps to solve social problems and help enrich lives.

Li Xiang, a student at Zhejiang University, developed a mobile app with two schoolmates that can help users develop good habits by building and feeding virtual electronic pets.

A special digital pet is produced in the app Weier, which sounds similar to the English word “well”. A user’s daily behavior is used to help it grow.

“When users complete their daily exercise goals, their electronic pets will also be full of energy, and when they go to bed too late at night, their pets will have black circles under their eyes,” Li said. The digital pet is like a projection of the user in the virtual world. But unlike other digital projections that focused on the similarity with the user’s physical appearance, the app cares more about the user’s character and behavior.

The app is one of more than 1,400 projects developed by students from more than 500 universities in the 2021 Mobile Application Innovation Contest, co-organized by Zhejiang University and the US tech company Apple Inc.

Tim Cook, CEO of Apple, said in a post on Weibo that it was great to see the talent on display at the contest. Students designed winning apps that help deal with important issues like improving access to healthcare and technology.

“Many of these young developers have gone on to become entrepreneurs, developers and teachers in their own right, and they are using the skills they’ve learned to make the world a better place,” Cook said.

“Every student should have the opportunity to create something that can change the world, and we’ve seen firsthand how coding has changed the global economy, creating new industries and supporting millions of jobs,” said Isabel Ge Mahe, vice-president of Apple Greater China.

5 . In the U.S., about 30 million children and teens take part in some forms of organized sports, and more than 3.5 million injuries happen each year. Almost one-third of all injuries from childhood are sports-related injuries. More than 775,000 children, aged 14 and younger, are treated in hospital emergency rooms for sports-related injuries each year.

Obviously, some sports are more dangerous than others. For example, contact sports such as football can be expected to result in a higher number of injuries than a noncontact sport such as swimming. However, all types of sports have a potential for injury, whether from the collision (冲撞) with other players or from overuse or misuse of a body part.

Most of the injuries happen as a result of falls, being struck by an object and collisions during unorganized or informal sports activities. Some are caused by poor training practices, or not warming up enough.

There are two kinds of sports injuries. Acute injuries happen suddenly, such as sprained (扭伤) ankles. Chronic injuries happen after you play a sport or exercise over a long period of time.

Sports injuries are first treated with R-I-C-E: Rest, Ice, Compression (pressure on the injury), and Elevation (raise the injured area above the heart). Doctors will treat more serious injuries with medications, by limiting movement, or by recommending operations, physical therapy, and rest.

You can prevent many kinds of sports injuries by following safe exercise habits.

7 . To keep social distancing and work at home during the pandemic (流行病) has led to less time moving around, and more time sitting and looking at screens. For many office workers, working at home means spending hours sitting at our desk.     1    . Therefore, exercise experts suggest things must be changed. Some tips here are to help you move more.

Start small

People trying to start exercising often get caught up in an “all or nothing” thinking which means either I do zero or I do two hours. And if I don’t get two hours, then it doesn’t count, or it’s not good enough.     2    . Going from no activity at all to even a little bit will indeed get some health effects.

    3    

Part of developing a good exercise habit is to know yourself well. Knowing what’s possible and what’s not realistic for you. For instance, if you’re not a morning person, don’t plan to exercise in the morning. And if you hate running, don’t run just because someone tells you it’s good for you.     4    . Arranging with a friend to work out will help you avoid struggling to get started.

Walk whenever you can

Sitting less and walking more will make a big difference. Use your stairs instead of an elevator. And if you don’t have to go out, just walk room to room back and forth to get those extra steps. If you have a meeting, use the break of that meeting to walk around.     5    

A．Make sure to know yourself well

B．Choose a suitable time for yourself

C．All these steps will count and be helpful

D．That’s a great place for everybody to walk

E．But five minutes is believed to be better than none

F．And it is ruining our health physically and mentally

G．You can think of possible ways for you to start or stick to

8 . In the 2021 Tokyo Olympic Games, the athletes were fighting hard to win glory for themselves and their country. Do you care about the gold medal count? Shouldn’t we just enjoy the game? Readers share their opinions.

George

The spirit of the Olympic Games is about sportsmanship and performing your personal best, which brings the whole world together under peace and competition. It was never purely about winning gold medals and dominance, as no single athlete can dominate (统治) the whole Olympic Games. The spirit of the Olympics also give an important message to the world that no single country should seek to dominate over others.

Eric

None of the athletes who fail to win a gold medal have anything to be ashamed of. If they win a medal, great! If they don’t, we know they did their best. One minute on stage, 10 years of practice off stage. The small medals contain their countless efforts. Gold, silver, bronze, even if they didn’t win any medal, we cheer for them and are proud of them. Go China!

Allende

The Chinese delegation has been put on too much pressure, which is unfair to all hard-working athletes. A gold medal is not everything. Think about those players who lost the gold but tried their best, most people do not show friendly sympathy to them, but even lightly blame them, and I was one of these people. I have to take this occasion to apologize for my behavior. Don’t create unreasonable pressure, you are not the one playing the game!

1. What do George and Eric have in common?

A．They are excellent athletes.	B．They are lack of sportsmanship.
C．They look at win and loss objectively.	D．They care about medals too much.

A．He is sorry for what he did.	B．Chinese players hope for mercy.
C．Pressure results in unfair competition.	D．Most people feel pity for the losers.

3. Where is the passage probably taken from?

A．A personal diary.	B．A research paper.
C．A newspaper report.	D．A story collection.

9 . What is the best sport for your body type?

Just because someone has dreamt of playing football from childhood does not mean it is the best sport for him or her. Finding the sport your body is best suited to can make a big difference to how much you enjoy it and how good at it you are.

A person with an ectomorph body type is tall and slim with little fat or muscle. This person has narrow shoulders and hips, and thin arms and legs. Ectomorphs have difficulty putting on weight because of a fast metabolism (新陈代谢).     1     . What suits ectomorphs is endurance sports. Marathon running, swimming, and football are excellent choices for them.     2     , basketball may also be a great option.

Mesomorph body types are the typical image of an athlete. Their arms and legs are muscular and they have broad shoulders and narrow hips. Mesomorphs can put on or lose weight easily and build muscle quickly.     3     . Possibilities range from weightlifting and boxing to cycling for shorter distances.

A person who is an endomorph naturally carries more body fat. They are often short, with a high waist, and well developed upper arms and thighs.     4     , they can be very good at power sports because of their larger mass. This body type is not suited for agility (敏捷) and speed, but strength activities like wresting or powerlifting can be a great fit.

It is important to note that the three body types are extremes. No one is 100% ectomorph or completely endomorph.     5     . Another key point is that diet and environment also contribute to athletic ability and genetics plays a large part. And the most important thing is to choose a sport you enjoy.

A．Everyone is a bit of a mix

B．If you want to be a world champion

C．If a person with this body type is very tall

D．A person with this body type has more choice of sports

E．For the same reason, it takes them longer to build muscle

F．While it may seem that an endomorph will not be very athletic

G．Endomorphs must work a little harder to maintain a perfect body weight

10 . Sobhi from Egypt, who has worked as a bodybuilder for almost 60 years, often says that age is just a number. Whenever people ask him when he is going to retire, his only answer is “never”.

It is generally accepted that people grow less active and lose passion for life as they age. However, Sobhi believes that age can never block ambitions if people still have strong wills.

Sobhi’s love for sports started when he joined his school gymnastics team. He once won the third place in Cairo’s Gymnastics Championship. In university, he started to pay more attention to bodybuilding, not only for a better shape, but also for a better health.

His body is so well-shaped that it even helped him appear in a famous film. Sobhi played a minor role of a muscleman in the film, which was filmed in Egypt and tells the story of an Ancient Roman soldier who was sent to Egypt by Julius Caesar to monitor one of his commanders.

As an 80-year-old man, Sobhi said training hard and having a good exercise schedule as well as a healthy diet are the real foundations of bodybuilding. He warned young people that taking bodybuilding supplements (补充剂) can lead to health risks. He recommended them to go for vitamins and other all-natural supplements that do not cause harm.

“Sobhi is 40 years older than me, but he does his exercises as if he is much younger than me,” Gabr, an athlete, said. He also said Sobhi is a great example for all athletes at the club, where Sobhi has been working out for the past 40 years. They are lucky to do sports with such a “hero”. “We watch him working out in shock. We wish we could just be like him when we are at his age,” Gabr added.

1. What does the underlined word “passion” in Paragraph 2 probably mean?

A．Love.	B．Encouragement.
C．Production.	D．Dislike

2. What did Sobhi once work as?

A．An advisor.	B．A fitness trainer.
C．A teacher.	D．An actor.

3. What did Sobhi advise young people to do?

A．Train as hard as they can.	B．Exercise whenever they like.
C．Take all natural supplements.	D．Pay more attention to body shape.

4. What did Gabr show for Sobhi in the last paragraph?

A．Affection.	B．Admiration.
C．Hatred.	D．Requirement.
