1 . Bookstores are fascinating places. That’s because the books on the shelves can take you away to magical lands, help you learn a foreign language, or cook a delicious meal. But when your community is too small to house a real brick bookstore, sometimes you have to make a compromise. A mobile bookstore that brings books around the country was the result. That is the case for Rita Collins, 70, who dreamed of opening a used bookstore after retiring from teaching.
A business planning class from the American Booksellers Association convinced Collins to abandon her idea that opening a bookstore in the small town where she lives, which would not be sustainable. Eureka, Montana, located just seven miles from the Canadian border, only has a population of 1,517. Collins asked her instructors about a traveling bookstore on wheels and they were skeptical. But she persevered.
Collins was inspired by Dylans Mobile Bookstore, a traveling bookstore in Wales run by Jeff Towns. She contacted Jeff for advice but she was largely on her own when it came to building her bookstore. First, she had to find a vehicle large enough to stand in. Then she had to have it refitted with shelves that would hold the books at a 15-degree angle so that they would stay in place while in transit. Collins named her bookstore St Rita’s Traveling Bookstore, which has been on the road since 2015.
At first, she drove through Montana and then she made her first cross-country trip in 2016. After she retired in 2017, it became a full-time job all year round. Collins and her mobile bookstore have visited 30 states, stopping at festivals and events along the way. While the locations change, some things always stay the same. Collins loves meeting people and making connections. While she loves what she does, Collins doesn’t think she can keep doing it. In several years, she hopes to pass her traveling bookstore onto another bibliophile who shares the same interest and will keep it on the road.

2 . Independent living at home is the ideal for every aging person. But a fall or other health-threatening incidents can change everything rapidly.
The wearable “panic buttons” introduced in the late 1980s were a great advance. But they only work if people actually wear them and can reach the button in an emergency. Today there are passive wearables that automatically detect falls, and camera-based systems to monitor elder safety.
Coming from a 40-year career in the semiconductor and wireless communication field, Rafi Zack decided to find a better alternative. “People aren’t devoted to wearing small devices 24/7, and camera-based systems are an invasion（侵犯）of privacy,” he points out, “The most challenging aspect is a fall. How fast we can detect a fall matters because the medical situation worsens quickly. Sometimes people stay on the floor for a long time. We have to find out how to solve that problem.”
Zack is a co-founder, CEO and vice president of R&D at EchoCare Technologies which has developed ECHO (Elderly Care Home Observer), a cloud-connected monitor based on radar technology and machine learning.
Because radar sees through walls, one ECHO unit fixed on the ceiling or wall can monitor one person (or two persons, in a future version) in a standard-sized apartment in a senior living facility. The device detects falls, breathing difficulties, drowning in a bathtub and other dangerous events. It gives out warnings to potential health worsening conditions by continuously monitoring and analyzing the person’s location, posture（姿势）, motion and breath. EchoCare tested the device in the United States, Japan, Australia and Israel. ECHO was certified（认证）in 2019 in Japan with the most aging population in the world.
“Bathrooms were the main testing area where about 17,000 deadly accidents happen annually.” said SMK Director and Executive Vice President Tetsuo Hara. “Bathroom makers, home security service providers and nursing homes are highly interested in EchoCare’s solution.” Zack noted, “As more and more elder people live alone as a result of social distancing, there is an increased need to monitor them without the burden of wearables or privacy-invading cameras.”

3 . My life as a tax-paying employed person began in middle school, when, for three whole days, I worked on an assembly (装配) line. My best friend Betsy’s father was an executive (管理者) at Hough Bakeries, which, at special festivals, made little rabbit-shaped cakes for all its stores. The plant downtown needed eight kids for temporary help, and the shift (轮班) fell over spring break, during which I had no plans. Cake? I loved cake-icing especially. I’d earn minimum wage. I’d see how a factory worked. My parents thought all of this was a grand idea for a girl like me and called Betsy’s dad with their permission.
Our roles on the line were simple: Place cakes on conveyor belt. Attach icing ears. Apply icing eyes and nose. Remove the cakes from belt; place onto trays. This was harder than it sounds. With your mind wandering, the cakes pile up. As I told my parents that first night, it was all a little more high-pressure than I’d expected. Dad smiled. This was the sort of work that made you appreciate the money you earned, he told me. And if your feet hurt or the minutes felt like hours, well then that was just motivation to keep those grades up and get that college education.
And the icing? We kids were allowed to eat as much as we wanted. By noon the first day, I could barely look at the stuff. To borrow a favorite phrase from my father: The executives weren’t born yesterday.

4 . Flocks of hundreds of regent honeyeaters（王吸蜜鸟）could once be spotted all over south-eastern Australia on a regular basis, but today the species is critically endangered, with only 300 believed to exist in the entire world. They were also known for the complexity of their mating songs, but as their numbers started declining, scientists started noticing male regent honeyeaters didn’t even sound like their species anymore. Today, there is enough evidence that regent honeyeaters have forgotten how to sing, which could cause the entire species to go extinct.
At one point, Australian scientists noticed that male regent honeyeaters were imitating（模仿）the songs of other bird species. Some experts believed that the imitation was a purposeful strategy to avoid attacks from their enemies. However, a recent study showed otherwise. Young regent honeyeaters learn their songs from adult members of their species, just like human children learn to speak, but because they are spread so thin in their habitat-they could occupy probably 10 times the size of the UK but are really small in quantity-many males don’t get to listen to the right songs, so they start adopting the tunes of other bird species. The problem is that these aren’t the songs female regent honeyeaters want to hear, so their chances of finding a mate are very slim.
Scientists are now planning to catch wild males that can sing and put them next to caged regent honeyeaters so that the young birds can learn the right song. They then plan to release them into the wild every few years, where they will hopefully be able to attract females and reproduce.
“This study shows how damaging population declines and habitat fragmentation（碎片）might be to this critical process in the life of songbirds,” said Dr Sue Zollinger, an expert in animal communication from Manchester Metropolitan University.

| B．Introducing wild birds to teach caged ones. |
| C．Training them to escape from the enemies. |
| D．Spreading them in different habitats. |
| A．To indicate the difficulty of catching wild birds. |
| B．To offer some strategies for animal communication. |
| C．To point out the critical tunes of the bird’s mating songs. |
| D．To stress the significance of an ideal population per habitat. |
5 . On July 24, 2020, Mike Stout launched his kayak（皮筏艇）just before 8：30 a.m. About 56 miles and 16.5 hours later, he landed on the sandy Michigan shore. It was his second time crossing Lake Michigan.
By chance, Stout said, he gave kayaking a try in 2016. Already in good physical condition, he considered kayaking a weekend escape. Then he was challenged by a client of his firm to think bigger. He did go big quickly. Weekend kayak trips were 40, 50 and 60 miles long over the next few months. Then his goal was to cross Lake Michigan that year. On August 3, Stout completed his first crossing of Lake Michigan in 15.5 hours. Since then, he’s finished countless long-distance trips on Minnesota rivers and lakes.
In heading back to Lake Michigan last summer, Stout thought he could become the first kayaker to make a round-trip crossing of the Great Lake. He felt capable. He’d put in 800 miles since March 1, 2020-when ice was still on the Minnesota River.
Stout wanted to do with manageable winds. Possibilities rose, only to become worse, the lake showing its mercurial nature. Stout realized a single crossing was his best hope. With local police informed of his plans and plenty of food aboard, Stout launched. His plan was to land on the Michigan shore 12.5 hours later. The lake thought otherwise. The winds and waves were working against him, too. Still, he was resolute. Finally he could hear waves crashing on shore.
“Never did I have a sense of doubt or fear or worry,” Stout said. Despite the constant, forceful wind, he said the crossing was easier than his others because of his experience. But no less meaningful. The stars, the chance to speak to the heavens, and the hope that his adventure would inspire others-all were fuel to finish.

| B．He intended to escape real life. |
| C．He was organized and determined. |
| D．He set a goal bigger than his capability. |

6 . My 12-year-old daughter, Lauren, came home from school yesterday, proudly waving her grade book to me. She had been awarded A-1 in most subjects such as mathematics, language arts and science—a great achievement! Then she sadly pointed out that her perfect score was damaged by a B-1 in French and a C-1 in Physical Education.
I asked her what the scores meant. She said that the letter showed the achievement(成绩) and the number showed the effort. That moment I realized that the grades were misleading. I reached out my hands and gave her a big hug and told her in my mind she had a perfect score. It didn’t matter that her grade in French was a “B”—the “l” showed that she had tried her best. That is something to make any parent proud.
Everybody is different. Everybody has different potential(潜能). Not all of us will become linguists(语言学家) or sports stars. But without 100％effort no potential can be achieved. If I see a salesperson fail at sales, the first thing I want to examine is the effort being put in. If there is a problem with effort, the salesperson has no future. But if I see a salesperson isn’t successful with l00％effort, he or she is worth my effort in helping. Maybe a bit of training or some advice from a more successful person will help. I know that 100％effort, focus in the right direction, will always bring a result whether that is an “A” or a “C”. As long as you make 100％effort, you are great.

7 . A new study found evidence that dogs developed in physical ways to present “puppy dog eyes” as a way to help connect with humans.
The study compared the facial muscles(肌肉) of dogs and wolves, which share ancestral history. Dogs broke off from wolves after being domesticated (驯化) about 33, 000 years ago. During that time dogs changed physically and behaviorally to adapt to life with humans.
The researchers examined the heads of six dogs and two wolves for comparison. They found the facial structures of both animals were mostly very similar. But one major difference was found above the eyes. The dogs were found to have two well-formed muscles around the eye that were not present in the wolves. These small muscles permit dogs to raise their inner eyebrows, the study found.
Juliane Kaminski, a comparative psychologist from the research suggests this eyebrow-rising movement causes “a warm” feelings in humans because it makes the dogs’ eyes appear larger. This expression also makes the dog look more like a human baby. The eye movement is similar to that which humans make when they are sad.
“The evidence is very obvious that dogs developed a muscle to raise the inner eyebrows after they were domesticated from wolves, ” Kaminski said.
In a separate part of the study, the researchers observed how 27 dogs and nine wolves interacted with a human. “We also studied dogs’ and wolves’ behavior. And when exposed to a human for two minutes, dogs raised their inner eyebrows more and higher than wolves,” Kaminski said.
The researchers suggest that the eye movements developed over time as a way for dogs to get humans to do things for them, such as giving them food, care or attention.
The only dog species in the study that did not have the muscles was the Siberian husky, which is an ancient kind of dog. The husky could be the best living example of what the link between dogs, and wolves looked like.

8 . If a president and a philosopher owed their success to the same secret, would you try to follow it too? What if the secret was something you already knew how to do? In fact, you probably do it every day. Here's what Friedrich Nietzsche wrote: “It is only ideas gained from walking that have any worth”. Thomas Jefferson: “Walking is the best possible exercise. Accustom yourself to walking very far.”
Are you still sitting there reading this? Get walking! It is not just the two great minds who made a case for it as a main creativity booster（推动）. Researchers have traced numerous connections between walking and novel ideas. A Standford University study found that participants were 81% more creative when walking as opposed to sitting. According to the study, walking outside—versus on a treadmill（跑步机）—produces the most novel and highest-quality ideas in participants who walked and then sat down to do creative work.
The movement aspect of walking is obviously key. You've probably heard the phrase “exercise your creativity”, which refers to the brain as muscle. Our creative thinking is triggered by physical movement, which is exactly why walking—with your dog, a friend or alone—feeds creative thinking.
But the scenery is almost as important as the sweat. A survey reveals that Americans spend 87% of their time indoors. Being inside, you're more likely to have less energy. Without energy, you can't wonder or create. Interrupting your routine with a walk can be a catalyst（催化剂）for gaining fresh insights into problems or projects. Just by going outside，you are stepping out of your comfort zone which is necessary if you want to open your mind to new possibilities. You can walk through a tree-filled neighborhood or a park and observe people wandering or birds singing.
So instead of setting a fitness goal, why not set a creative goal that starts with walking? Engage more closely with your surroundings. Walk just for exercise. Walk for wonder.
1. Why are the two great minds mentioned in Paragraph 1?| A．To suggest the way to exercise | B．To show the benefits of walking. |
| C．To give the definition of success | D．To stress the importance of creativity |
| A．Motivated. | B．Blocked. | C．Controlled. | D．Changed. |
| A．Americans spend most of their time enjoying it. |
| B．One can't wonder or create without it. |
| C．It can build a comfort zone for people. |
| D．It will expose people to new chances. |
| A．Scenery inspires new ideas. | B．Your creativity lies in sweat. |
| C．Exercise feeds creative thinking. | D．Your brain is made for walking. |

10 . It was just the three of us—my parents and me. My dad is a truck driver, and when I was a little kid, he was gone most of the time, delivering supplies around the Mid-west. Then we moved to a small house in Brighton. Colorado on my third birthday. There weren't any kids my age in the neighborhood, so I mostly played in the yard with the dogs. I had a lot of imaginary friends—a whole family, actually, with a husband, children, a best friend...no joke.
My first memory is our neighbor Arlene handing me strawberries from her garden. One day, my parents asked Arlene and her husband Bill whether they'd watch me when they went out. This worked well, so it became a weekly occurrence.
When I was about five, I had an idea: “What if I adopted Bill and Arlene as my grandparents?” I knocked on their door and said, “Will you guys be my grandparents?” They started crying and enthusiastically accepted it. Soon after, they printed out an adoption certificate and it hung on their living room wall from then on.
I remember being surprised that they took my offer so seriously. Thinking of that moment still brings tears to my eyes. There's something truly remarkable about a child offering her love and adults being so ecstatic to accept it. From the day I adopted them, I called Bill and Arlene grandpa and grandma. Pretty soon, my parents were calling them Dad and Mom. Even our animals would often sneak out of our yard to visit them. Over the years, Bill and Arlene supported me in all my dreams. And when I got accepted to a university, they presented me with a fund. They told me they'd been putting away money since the day I adopted them.
After Arlene passed away, Bill gave me the ring he'd gifted to Arlene. It's a simple gold band that I wear on my ring finger as a reminder of the kind of love I wish to put into this world.
