Why do Olympic athletes push themselves to the limits? One of the Olympic triathletes personifies the phrase herself.

To get to the top, she has made an endless list of sacrifices and it     1     this: she was born with an enormous amount of drive and determination. From a small girl, she would stay in at lunchtime just to     2     on class work; she would ride on the bus on her own at ten years old and go to swim 100 length is of the pool. This was time she could have spent with friends, playing and engaging in other pursuits. Later,     3     achieve glory in professional, she had undergone much physical and mental intensity. However, inspired by another stellar triathlete, she was always willing to do an extra little bit during her every workout, which gradually     4     from the other competitors.

Having been through fears and tears, she never regrets. To reach the winner's platform, athletes should     5     their sport. It is hard to live a life in a normal and balanced way, but these words are not used for the athletes who     6    .

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.

7 . 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.

There is a photo hanging above my desk. Whenever I look at that photograph, it takes me back to those early years     1     every new experience was important for me.

I can still remember the shouts of the spectators as I     2     (go) out onto the sports field with my classmates. Two days     3     (early), I had qualified for the finals of the 100 metres. Now looking around,     4     was determined to win.

While I was walking across to the start, I began     5     (feel) more and more nervous. I looked around and saw my proud parents waving enthusiastically. My heart was beating fast when I lined up with the other eager competitors. I look some deep breaths and waited for the signal. Then the starting signal     6     (give) and I set off down the track.

I ran as fast as I could, not looking at anything but the finishing line. By the time I crossed the line, I was so exhausted that I     7     hardly breathe. As soon as I heard the result announced, I realized I     8     (win)! Overjoyed, I collapsed on the soft grass with a broad smile     9     my face.

“Well done!” said     10     headmaster later, as I was presented with the winner’s certificate. I had never felt so happy and proud in my life.
