2 . Age is truly just a number if our hearts are young. Lee Minor, an 85-year-old retired psychologist, has________this by finishing his 600th marathon race with 32 members of his family by his side. “Runners don’t have a________line. We just keep going,” he toldGood Morning America. “I felt________running with my family.” Minor has been running three days a week since 1969, and his heart is filled with enthusiasm for running.

“I like to run in all kinds of________. It is so childish as the rain touches your face. And I love to come here after snow and you watch your________as you go along.” he concluded.

Minor’s enthusiasm for running is________. “It is my joy. And I want to live as long as I can. And I mean live, not________.” His words ring true for Ron Robert, a man diagnosed with Alzheimer’s disease who decided to ________ a three-year bachelor of artsprogram at King’s University College in London, Ontario. “I was always taught early in life that the brain is like the most ________instrument we have in our body,” said Robert.

Last fall, Robert graduated from the university, despite the challenges of his illness. “When I went across the stage, and as I’m getting my________, the kids all stood up andyelled and clapped,” he________. “I had to hold back the tears. It was something else, just wonderful.” He hopes that his story will give hope to others facing________difficulties. “There will come a time when I won’t be able to, and I fully________that. Butin the meantime, I’m living a full life.”

The stories of Minor and Robert are reminders that age and illness need not________us. We can choose to pursue our________and live life to the fullest, no matter whatchallenges we may face.

3 . Recently, I accidentally found a set of Hanfu l only wore once from the bottom of the cupboard. I remember buying them simply to match the ancient-style hair accessories (配饰) a friend gave me. It occurred to me that 1 had been trapped in the “birdcage effect”.

“Birdcage effect” means that when you get an item one day, you will prepare more things to match it. Weeks ago, I was in the company of friends engaged in shopping. One said that she wanted to buy a good writing pen to match the delicate notebook that her sister gave her, so that she would fall in love with taking notes on reading, and thus love reading, not just reading. I joked that she must have fallen for the “birdcage effect”. But the friend said with a smile: “Why not use the ‘birdcage effect’ instead?”

For the first time, I heard that the “birdcage effect” can be used in reverse (逆向). However, this can’t help but remind me of middle school, and I seem to have used the “birdcage effect”. Passing by a bookstore one day, I purchased a magazine and saw the call for contributions published in the magazine, so I started writing with eager hands, and then I fell in love with writing.

After shopping with my friends that time, I began to proceed to use the “birdcage effect”. I bought a small fresh tablecloth to decorate my desk, and a beautiful notebook to record my inspiration. When everything was ready, I started writing again.

But how can we get rid of the “birdcage effect” in many things, and even use the “birdcage effect” in the opposite way? Various “birdcages” unavoidably appear in life, but we can distinguish them. If it is not in line with the actual situation, it is a “negative birdcage”, then we must learn to stop losses in time and maintain a heart of abandonment and separation. If it is a “positive birdcage” that motivates us to develop upward, we can clarify our goals, shop or decorate appropriately, and motivate ourselves to move towards our goals. At this time, you will find that the “birdcage effect” is actually not so terrible!

4 . Goldfish may seem like simple creatures swimming in a glass tank, but they possess a rather complicated navigation system, as discovered by researchers at the University of Oxford Led by Dr. Adelaide Sibeaux, the study aims to shed light on our understanding of how fish, and potentially humans, estimate distances using what could be described as an internal GPS.

Writing in the journal Proceedings of the Royal Society B, Sibeaux and colleagues report how they created a tank in their experiment with 2cm-wide black and white vertical stripes (条纹) on the walls, connected by similar stripes across the floor. The team trained nine goldfish to swim a set distance of 70cm and then return to their starting point when waved at. The experiment aimed to investigate how the fish would estimate this distance without any gestures, under different patterns.

Over multiple trials, the goldfish averaged a swim distance of 74cm, give or take 17cm, when presented with the vertical 2cm-wide stripes. However, when the stripe pattern was altered to either narrower vertical stripes, checked patterns, or horizontal stripes, the fish’s behavior changed significantly. Narrower vertical stripes led them to overestimating the distance by 36%, while horizontal stripes resulted in highly inconsistent estimations.

According to the researchers, the goldfish appeared to be using an “optic (光学的) flow mechanism” based on the visual density of their environment. They kept track of how frequently the vertical pattern switched between black and white to estimate how far they had traveled. The study suggests that different optic flow mechanisms are used by mammals, including humans, based on angular (有角度的) motion of visual features. The study implies that the use of visually based distance information could have emerged early in the evolutionary timeline.

“This study is novel because, despite knowing that fish respond to geometric information regarding direction and distance, we don’t know how they estimate distances,” Professor Colin Lever, although not involved in the study, said, “it’s exciting to explore fish spatial mapping because fish navigation evolved earlier and better than most mammals.”

5 . As a boy, John Kerr wanted to be a park ranger (护林员). ________, he spent four decades at a public broadcasting’s station in Boston. He ________ at the age of 65 without any particular post-career goal in mind.

After several lazy weeks, he drove to visit his family by Yellowstone. On the way he ________ stopped at the Yellowstone Park Foundation, which raised funds for the national park. As it happened, the foundation was ________ people to educate park guests on wolves. Kerr ________ for an internship (实习).

To say that Kerr stood out in the intern crowd is a massive ________. Most interns were college and even high school students. But, in a sense, he had been ________ for this since his youth. His outdoor adventures with his grandfather had given him a love of ________, and he once volunteered at the local fire department on ________ calls.

From his internship, he ________ a ranger sooner, educating park visitors, making for safe ________ between guests and animals, and responding to medical emergencies. He ________ his job of what he describes as one in the most beautiful places, and moments when he treats a visitor to an ________ look at one of the park’s wolves or bears through his telescope, an ________ that can move visitors to tears.

“These are ________ and all-too-rare moments,” recalls Kerr. “I never forget them.”

9 . Accompanied by her father, using a combination of aid and free climbing and taking advantage of some special equipment and ropes for protection, 10-year-old Selah made it to the top of El Capitan on June 12 after five days of big wall climbing.

Climbing the challenging and adventurous Nose route of El Capitan was a labor of love for Selah in more than one way. Her parents , Mike and Joy Schneiter, fell in love on this 3,000- plus-foot huge rock and she has always wanted to feel the way that her parents felt when they were up there together. Selah showed great interest in rock climbing at an early age. She wore her first rock-climbing equipment shortly after she learned to walk. She first dreamed of climbing El Capitan when she was 6 or 7.

El Capitan is a famous mountain-sized rock in Yosemite National Park. Getting to its top is no easy task. It's taller, as reported, than the tallest building in the world-Dubai^’s Buri Khalifa. El Capitan and its difficult Nose route, which runs more than 3,000 feet high up the center of the rock's face, is considered one of the world's hardest big wall climbs and has attracted the best climbers over time. But never before had a youngster accomplished it.

Selah's achievement caught national attention. Outside Magazine called her the youngest documented person to climb the Nose. Ken Yager, president of the Yosemite Climbing Association, said he also couldn't think of anyone younger who has done it.

Selah is humble about her El Capitan accomplishment. "I'm not necessarily a special kid or anything like that, she said. "There were a few times when I would be so worn that it would kind of discourage me from holding on. But overall, it was just great to keep plugging away.”

Selah shared this advice for other young climbers dreaming of big walls, "It doesn't take necessarily a super special person to do something like that. You just have to put your mind to it.”

10 . My mom loved to pass her wisdom to me: ”Nothing beats a good bite that bites back.” She was referring to her bitter-taste foods like dill pickles and rhubarb (大黄叶). But I was not a big fan.

Three years ago, I finally decided to ask if I could ________ out her rhubarb while weeding the garden. “________ not!” Mom gasped, throwing me a(n) ________ look. Clearly, I had underestimated her________ for it. However, as I continued ________, I thought about how rhubarb is one of the first to appear in spring. It ________ the snowy ground before the arrival of other plants. How can anyone fail to ________ it? When those first sprouts (嫩芽) appeared, Mom would count them like a ________ counting a newborn’s fingers and toes.

When I was a kid and my mom gave me that pie, it made me ________ to try. In my teens, it made me complain about the bitterness. Even ice cream or candies did not ________ the deal for my young taste buds (味蕾). Rhubarb was something to be ________ at all costs.

Then, last summer, I came across the ________ for her rhubarb pie in an old drawer. So I decided to give it a ________. A few attempts later, I served rhubarb pie to family and guests. All agreed, including me, that it tasted incredible.

Since then I’ve come to a ________ about rhubarb. Rhubarb’s taste may be lost on children, but adults can________ it. Like my wise mother, I now understand that “Nothing beats a good bite that bites back.”
