2 . 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.

3 . “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

4 . 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.

5 . 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。

I grew up in southeastern Michigan. I was a fan of Detroit Tigers, a famous baseball team, as a young boy.

My childhood dream was to be like my hero, Al Kaline, and someday play for the Tigers. My Dad would take me to Tiger Stadium several times a year and my hero Al Kaline would never let me down. We never attended a game that he didn’t get at least one hit.

I was crazy about baseball. If there was a game in my high school, I was never absent. I kept practising so that I could achieve my dream of playing for the Tigers, and I was doing well at each level of play. Later, I got a chance to sign up for a strong American Legion baseball program. There I met our coach, Bob Ohm, who knew a lot of baseball and taught each of us the basics as well as more advanced baseball skills. With Bob Ohm’s help and my hard work, I had set new records in many baseball championships.

My dream to be like my hero seemed to draw near. One summer, I went up to play the final season in Marinette. There were scouts who came to find the best players. This was it! My big chance!

Well, as the game progressed I hit the ball very well getting five hits in the game. Unfortunately, I also made four mistakes. The final mistake actually drew laughter from the crowd.

注意：
1. 续写词数应为150个左右；

After the game, I knew my dream of playing professional baseball was lost.
