5 . At the end of a long day, it’s tempting to dive into your social feeds or Netflix queue the minute you've finished eating. But back before screens took up all our free time, an after-dinner walk was a popular activity. “Italians have been walking after meals for centuries,” says Loretta DiPietro, a professor at the George Washington University, “so it must be good.”

Research backs this up. One study co-authored by DiPietro found that when older adults at risk for type-2 diabetes (糖尿病) walked for 15 minutes after a meal, they had steady blood sugar levels in the hours afterwards. The human digestive system turns food into glucose (葡萄糖). After a meal, glucose floods a person’s bloodstream. Insulin (胰岛素) helps pull that glucose into cells. But for people with impaired insulin activity, too much glucose can remain in the blood, which can cause heart disease and other health problems.

What good does walking do? “The muscles we use to walk use glucose as energy, drawing it out of circulation and therefore reducing how much is floating around,” says Andrew Reynolds, a postdoctoral research fellow at the University of Otago. Reynolds conducted a study of people with type-2 diabetes and found that just 10 minutes of walking after a meal helped control their blood sugar levels. “We saw the biggest differences with walking after dinner time,” compared to other times of the day, Reynolds says. “The production of insulin in response to a meal tends to decrease later in the day. Getting up and moving around at that time was very effective,” he says.

A little post-meal movement may also aid digestion. But more isn't necessarily better when it comes to post-eating exercise. “Exercising muscles pull more of the blood flow their way during activity, and the GI tract (消化道) gets relatively less,” says Sheri Colberg-Ochs, a researcher at Old Dominion University. “That actually slows down the digestion of food in your stomach during the activity. Anything but really intense exercise would probably work equally well.”

So make like the Italians and head out for a walk after your next meal. Your TV and the Internet will still be there when you get home.

1. What does the underlined word “impaired” in paragraph 2 mean?

A．Related.	B．Monitored.
C．Damaged.	D．Expected.

2. What might be concluded from Reynolds’ words?

A．The body's ability to manage blood sugar varies in a day.

B．Insulin's function can be activated by exercise.

C．Moving around later in the day helps with sleep.

D．Dieting plays a part in controlling blood sugar levels.

3. What is wrong with really intense exercise according to Colberg-Ochs?

A．It damages the GI tract.

B．It delays digestion.

C．It causes breathing problems.

D．It increases blood sugar levels.

4. What is the text mainly about?

A．The health tips of Italians.

B．The danger of long-term sitting.

C．The health benefits of post-meal walks.

D．The causes of type-2 diabetes.

6 . Though the Tokyo Olympic Games drew to a close on August 8, 2021, the public is still watching the athletes. Their outfits and the technologies that helped them in the competition have aroused people’s interest.

Su Bingtian, the first Chinese sprinter to reach an Olympic 100m final, has ascribed his breakthrough to scientific training. “It takes Su 47 steps to run 100 meters. Each step counts,” Liang Dong, a member of Su’s training team, told Shenzhen Evening News. “Randy Huntington, Su’s American coach and a biomechanics expert in track and field, has collected a lot of data on outstanding sprinters and built a database. He put in all of Su’s data and got a near-optimal model. When Su is training, the team uses high-speed cameras to record his training and compares it with the model to find out his weaknesses.”

Technology has also brought a new boost to table tennis. On July 27, the semifinal match between China’s Sun Yingsha and Japan’s Mima Ito was in full swing at the Tokyo Metropolitan Gymnasium. You wouldn’t have guessed that besides players, referees and audiences, a powerful AI platform was monitoring the match.

Every serve, swing and movement of Mima Ito was captured by this AI cloud platform deployed in Tokyo. At an average speed of 100 Mbps, the data was transmitted to the technical team of the Zhejiang University Table Tennis Intelligent Big Data Analysis Platform,2,442 kilometers away from the Tokyo Metropolitan Gymnasium, according to The Paper.

The Tokyo Olympic Games have seen not only scientific support in training, but many high-end technologies in athletes’ devices. For example, the Kenya women’s volleyball team’s GPS devices fed data on each player’s strength, heart rate and so on to coaches, who used the information to prevent injury and personalize training plans for each individual, South China Morning Post reported.

B．Sprint.

C．Women’s volleyball.

D．Archery.

3. What can be a suitable title for the text?

B．A report about the Tokyo Olympic Games

C．An Al platform monitoring the Tokyo Games

D．Devices and Training Determine Athletes’ Competition

7 . 阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

“No 7, Jobie Nymble, takes the lead,” cried the announcer. “Just one more hurdle (跨栏) and ...” Cheers broke out. “Jobie Nymble from Riverside Middle School takes first place in the girls’ 100-meter hurdles!” The crowd went wild.

“County championships (锦标赛), here we come,” screamed Jobie, patting her green track spikes (钉鞋). They were her lucky shoes and she loved them. “Next Saturday, we’re taking home the gold,” Jobie whispered to her spikes, excitedly retying them.

“Don’t forget, guys,” said Marisol, one of her teammates. “My birthday party is next Friday at Hidden Park.”

Next weekend couldn’t come soon enough. Jobie smiled with excitement all week long. At track practice, she leaped over those hurdles faster than she’d ever leaped before. And it wasn’t long before everything in her path was a hurdle: flowerpots in her front yard, sidewalk cracks on the way to the bus stop and even her little sister, Teka!

The day of Marisol’s party, Jobie put on her favorite outfit: her blue shorts, an old track T-shirt from her dad, and her lucky spikes. “Perfect.” She smiled at herself in the mirror.

The party was under way when Jobie arrived at Hidden Park. She stopped by the track first, planning to do some practice.

“Jobie!” Two of Jobie’s teammates rushed toward her, breathless and barefoot. “Come on,” they yelled. “You have to try the slide.”

Jobie looked toward the party area. Suddenly, she saw it. The biggest slide she had ever seen was on the far side of the park. Smiling kids zoomed down the slide at unspeakable speeds. Without thinking twice, Jobie took off her spikes and dashed (猛冲) toward the slide. Its ladder stretched to the sky, but she reached the top in no time, closed her eyes and let go.

Jobie couldn’t get enough. She tried again and again. When it was finally time to go home, she unwillingly made her way back to the track where she’d left her shoes.

8 . The Biggest Stadiums in the World

People have been pouring into stadiums since the days of ancient Greece. In around 80 A.D., the Romans built the Colosseum, which remains the world’s best known stadium and continues to inform contemporary design. Rome’s Colosseum was 157 feet tall and had 80 entrances, seating 50,000 people. However, that was small fry compared with the city’s Circus Maximus, which accommodated around 250,000 people.

These days, safety regulations-not to mention the modern sports fan’s desire for a good view and comfortable seat — tend to keep stadium capacities (容量) slightly lower. Even soccer fans tend to have a seat each; gone are the days of thousands standing to watch the match.

For the biggest stadiums in the world, we have used data supplied by the World Atlas list so far, which ranks them by their stated permanent capacity, as well as updated information from official stadium websites.

All these stadiums are still functional, still open and still hosting the biggest events in world sport.

·Rungrado 1st of May Stadium, Pyongyang D.P.R. Korea. Capacity: 150,000. Opened: May 1,1989.

·Michigan Stadium, Ann Arbor, Michigan, U. S. Capacity: 107,601. Opened: October 1, 1927.
