5 . If you want to improve your fitness, walking is a great choice.     1     Here are a few tricks that may help you increase your walking stamina (耐力).

Walk for at least 30 minutes 3 to 5 days a week.

    2     But remember—don’t sweat it if you can’t walk this long at the beginning. Over time, your body will get used to a certain level of activity, and that makes it easier for you to walk longer.

    3    

If you only have a short period of time to walk, add force to work on your stamina. You can simply put a few books or solid objects in a backpack and carry that. Keep track of the amount of weight you’re carrying so you can increase it gradually.

Find ways to include walking in your regular routine.

Figure out how you can introduce more walking into your daily routine. For example, you might try using the stairs instead of the elevator.     4    

Download a step-tracking or general fitness app.

A fitness app allows you to set goals for yourself to stay active and increase your walking stamina over time.     5     These devices often measure the distance you’ve walked and include information about your heart rate and calories burned.

A．Carry weight while walking.

B．Some trackers also allow you to compete with others.

C．Go on a longer walk at least one day a week.

D．It’s free, simple, and adaptable to your schedule.

E．If the weather is unsuitable, use a stationary bike inside instead.

F．Or you can park further away from shops and walk the distance.

G．Going for regular walks improves your cardiovascular (心血管的) fitness gradually.

7 . Scientists are now digging into precisely why exercise holds so many benefits for our mental health and memory. The answer, studies say, lies in our brain chemistry.

Each time you work up a sweat, your body releases feel-good happy hormones (荷尔蒙), including endorphins, dopamine and endocannabinoids, the latter being responsible for the so-called runner’s high. Now researchers are also pointing to myokines (肌肉因子) as an important contributor to the mental health benefits of exercise. When our muscles contract, myokines are released into the bloodstream, helping your muscles and organs communicate. They think this communication increases resilience to stress, reduces symptoms of mental suffering and anxiety and has a direct effect on depression.

A 2021 scientific report published in Neuropharmacology showed evidence that myokines boost brain function, like improving memory and mood. “Myokines reduce systemic inflammation (炎症), which is especially beneficial for people with drug-resistant depression whose low mood is linked to high inflammation,” explains Dr Jennifer Heisz, an expert in brain health and associate professor in the department of kinesiology at McMaster University in Canada.

A recent study published in the British Journal of Sports Medicine showed that treatment for depression can be much more effective when physical activity is added to the usual care. Participants found benefits after 12 weeks of exercising for 30 to 60 minutes a day. “While exercise is not a replacement for professional mental health treatment, physical activity can complement and enhance the effects of the treatment,” says lead researcher Ben Singh, a research fellow at the University of South Australia.

“It is amazing to consider how moving our bodies can heal our minds,” says Heisz. Whether you’re cycling, walking around your neighbourhood or doing yoga, getting sweaty is good for your body and mind. To get the biggest overall health boost, the key is to zero in on sports and activities you enjoy, so you’ll keep going back to them.

8 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

My son Joey was born with disabled feet. The doctors assured us that with treatment he would be able to walk normally — but would never run very well. The first three years of his life were spent in surgery, casts and braces. By the time he was eight, you wouldn’t know he had a problem when you saw him walk.

The children in our neighborhood ran around as most children do during play, and Joey would jump right in and run and play, too. Although I was a little worried about his state, we never told him that he probably wouldn’t be able to run as well as the other children. So he didn’t know it. Every day after school, he would run and jump crazily, laughing cheerfully with his friends. Before bed, he was delighted to share everything that he enjoyed with me, and the brightness on his face drove away all my anxiety.

In his seventh grade, the school planned to hold a cross-country race. On hearing the news, he jumped with joy, and he decided to go out for the cross-country team. What worried me most was the extreme strength and patience that was required for the race. However, his strong determination eventually changed my attitude towards the event. I made up mind to be in favor of him. Every day he trained with the team. He worked harder and ran more than any of the others — perhaps he sensed that the abilities that seemed to come naturally to so many others did not come naturally to him. Although the entire team runs, only the top seven runners have the potential to score points for the school. We didn’t tell him he probably would never make the team, so he didn’t know.

9 . “The Worthington Christian defeated the Westerville North by 2—1 in an Ohio boys’ soccer game on Saturday.” That’s according to a story that appeared last month in The Columbus Dispatch. That lead was written not by a sportswriter, but by an artificial intelligence (AI) tool.

Many news organizations are now examining how AI might be used in their work. But if they begin their “experimenting” with high school sports because they are less momentous than war, peace, climate change and politics, they may miss something crucial. Nothing may be more important to the students who play high school sports, and to their families, neighborhoods, and sometimes, the whole town. That next game is what the students train for, work toward, and dream about. Someday, almost all student athletes will go on to have jobs in front of screens, in office parks, at schools, in hospitals or on construction sites. They may suffer blows and setbacks. But the high school games they played and watched, as well as their hopes and cheers, will stay vivid in their memories.

I have a small idea. If newspapers will no longer send staff reporters to cover high school games, why not hire high school student journalists? News organizations can pay students an hourly wage to cover high school games. The young reporters might learn how to be fair to all sides, write vividly, and attract readers. That’s what some celebrities in sports did, and do.

And think of the great writers who were inspired by sports: Hemingway on fishing, Bernard Malamud and Marianne Moore on baseball, Chen Zhongshi on football, and CLR James on cricket, who said, “There can be raw pain and bleeding where so many thousands see the inevitable (不可避免的) ups and downs of only a game.” A good high school writer, unlike a robot, could tell readers not just the score, but the stories of the game.

1. Why is the lead mentioned in the first paragraph?

A．To introduce an original idea.	B．To show AI’s wide application.
C．To bring in the opinion about AI.	D．To stress AI’s importance to news.

2. What does the author think of high school games?

A．Hopeful.

B．Eye-catching.

C．Competitive.

D．Far-reaching.

3. What is good sports news like according to the author?

A．Rich in contents.	B．Fair in comments.
C．Centered on results.	D．Targeted on readers.

4. Which can be a suitable title for the text?

A．News Organizations Are Abusing AI	B．High Schoolers Can Do What AI Can’t
C．Great Writers Are Crazy About Sports	D．AI Ruins High School Students’ Memory

10 . The rate of childhood obesity in the U. S. has tripled over the past 50 years. The American Academy of Pediatrics (AAP) made waves this year by recommending that doctors put obese kids as young as two years old on intensive, family-oriented lifestyle and behavior plans. It also suggested prescribing weight-loss drugs to children l2 and older and surgery to teens 13 and older. This advice reflects the organization’s adoption of a more active position on childhood obesity.

Yet the lifestyle programs the AAP recommends are expensive, inaccessible to most children and hard to maintain. Few weight-loss drugs have been approved for children. And surgery has potential risks and few long-term safety data. Furthermore, it’s not clear whether interventions in youngsters help to improve health or merely add to the psychological burden overweight kids face from the society.

Rather than paying close attention to numbers on a scale, the U. S. and countries with similar trends should focus on an underlying truth: we need to invest in more and safer places for children to play where they can move and run around, climb and jump, ride and skate.

Why is it so hard to get kids moving? Experts blame the problem on the privatization of sports — as public investment in school-based athletics dwindles, expensive private leagues have grown, leaving many kids out. In addition to fewer opportunities at school, researchers cite increased screen time and a lack of safe places for them to play outside the home. New York City, for example, had 2,067 public playgrounds as of 2019 — a very small amount for its large population. In Los Angeles in 2015, only 33 percent of youths lived within walking distance of a park.

Kids everywhere need more places to play. Public funding to build and keep up these areas is crucial, but other options such as shared-use agreements can make unused spaces available to the public. These opportunities aren’t primarily about changing children’s waistlines — they’re how we keep childhood healthy and fun.

1. What can we learn from the first two paragraphs?

A．Childhood obesity is well under control in recent years.

B．Weight-loss surgery are recommended to children 12 and older.

C．AAP plays a more active role in fighting against childhood obesity.

D．Expensive as it is, lifestyle programs are practical for most children.

2. The underlined word “dwindle” is closest in meaning to ______.

A．decline

B．quit

C．increase

D．develop

3. In the author’s opinion, what measures should be taken to create more safe areas?

A．Prepare fitness equipment at home.

B．Live within walking distance of a park.

C．Promote investment in private athletics.

D．Open up playgrounds when school’s out.

4. What’s the main idea of the text?

A．Sports play an important role in children’s growth.

B．More safe areas for outdoor fun are in urgent need.

C．Family-oriented lifestyles are crucial to children’s health.

D．Medical intervention is important to ease psychological burden.
