Cui Zhenshuo and Yang Bo discovered that because of the far location of most paper workshops and lifestyles of the paper-making craftsmen, their products are unable to reach the market     1     (easy). Therefore, Cui and Yang came up     2     the idea of establishing their own studio that could serve as a bridge to connect far workshops with buyers to advance     3     (tradition) Chinese handmade paper.

Chu is a kind of tree.     4     (it) bark (树皮) is a common material that was used in papermaking in ancient times. Han Yu, a famous     5     (write) during the Tang Dynasty (618-907) called paper Mr. Chu in his work Biography of Mao Ying. Since then, it     6     (use) as a nickname (昵称) for paper by Chinese scholars. In 2019, Cui and Yang named their own studio “I am Mr. Chu.”, and they focused on     7     (run) it.

Du Weisheng, an expert in the restoration (修复) of ancient books at the National Library of China, told them that, in     8     1990s, many Chinese paper relics needed to be repaired with handmade paper that allowed people to find information on various paper styles.

The two began to create the series of handmade paper products from 2021. Each volume is made up of thirty types of handmade paper, each of     9     is sourced from its place of origin. At present, two volumes of the series have been produced, and they plan     10     (make) ten volumes.

2 . My dad is easy-going and has a gift for chatting. He ________ a fast food restaurant called Queenie’s Weenies, which is specialized in hot dogs. I work with my dad at the ________ on weekends.

One Saturday, we went ________. As we got into the checkout line, I ________ something: our cashier (收银员) was very ________! She ________ no smiles, no greetings and no small talk. Her “anger aura (光环)” was obvious and kind of ________ to me. When we ________ to check out, I was thinking that we should just pay for our things and leave quickly. My dad had a different ________. When it was our turn, he started ________ her.

Dad said, “Hi, how are you today? This is my son. I have a restaurant, and we ________ together. It’s called Queenie’s Weenies. Drop by my restaurant sometime and I will ________ you to my hot dogs. I’m good at cooking them.” By the time we ________ checking out, the cashier was smiling. She said, “Thanks, umm… I hope you and your son have a very nice day.”

Back in the car, Dad said to me, “The cashier was obviously ________ today. It happens to everyone. Smile ________ or give a few kind words, which is all it takes to make one a little more delighted.”

3 . Animals, including humans, feel sound as well as hear it, and some of the most meaningful communication happens at frequencies (频率) that people can’t hear. Elephants, for example, use these low-frequency sounds to, among other things, find family or a mate across long distances. Whales do it, too.

But you don’t have to weigh a ton to make a sound. In fact, you don’t have to be bigger than a pea. Consider, for example, the tree-hopper, a curious little animal that lives on the stems (茎) of the leaves. University of Missouri biologist Rex Cocroft has spent much of his time listening closely to tree-hoppers with his team.

The team discovers that all the sounds being heard from tree-hoppers are produced by males. They do it by vibrating (振动) their abdomens (腹部) to make a wide variety of strange sounds. There is almost no airborne sound produced with these vibrational sounds. Cocroft explained, “If a tree-hopper were to stand on your finger and produce a sound, you would feel the vibration but hear no sound.”

They showed that some sounds, not surprisingly, seem to be aimed at attracting females. And some are aimed at other males.

Cocroft explained, “When two males meet each other, or when they are mate-searching on a branch, we’re hearing ‘purring, bdddddrrrr…’ sounds that males give.” Normally, a person couldn’t hear any of this, because the sound travels along the stem, inside it. And that’s how other tree-hoppers detect it.

Cocroft said tree-hoppers have very sensitive legs. And they stand around on stems, which are good at spreading vibrations. So they just use what nature gives them to communicate with each other.

“They have so many different forms of social behavior and grouping,” Cocroft explained. “And once there are animals living in groups, then there will be all sorts of interesting possibilities for communication.”

4 . By the time Joy Ryan, a US grandma, turned 85, she had never seen the ocean or mountains. For Joy, trips to the local fishing area with her husband were about the farthest place she had ever gone, even if she loved watching the Travel Channel.

But one day Joy’s grandson, Brad Ryan, discovered that he and his grandma had a common interest in their love for traveling, when they began to visit the American great outdoors together.

Brad said, “When I learned my grandma had never seen the great wildernesses of America—deserts, mountains and oceans, I thought there was something I needed to do.” It was after taking his grandma out of Ohio on a visit to the Great Smoky Mountains National Park that he came up with the idea of visiting all the 63 US national parks with her to create inspiring memories.

Going to all the 63 US National Parks is a huge achievement even for a much younger adventurer (冒险家). Brad said his grandmother’s physical strength (体力) grew with their trips. For example, his grandma went water rafting (漂流) at 91, with class three rapids and when walking at the New River Gorge National Park in West Virginia, she broke the record by almost a decade!

It wasn’t always like this, however. Joy was so wobbly (不稳的) on her first trip, challenged by her balance. A group of college students clapped their hands when she reached the top of a path they were following.

Joy broke her age limitation (限制) and at the age of 93, she made history as the oldest living person to visit every US National Park. Joy believes it’s the mix of hopefulness, willpower, and the good health that gives her strength.

5 . National Parks in Utah

Zion National Park

It’s perfect for scenic drives and outdoor adventures. One of the park highlights is the Zion Canyons, which offers different hiking (远足) opportunities. Late spring or early fall is the best time to visit Zion National Park, since most facilities are open during this time. However, if you don’t mind cold weather, visit during the late fall and winter.

Bryce Canyon National Park

It’s home to the greatest number of hoodoos (石林) on earth, which are one of the natural wonders of the world. You can see most of Bryce Canyon’s highlights in one day by taking the scenic drive and making stops at various views. Most people visit the park between May and September since the weather is warmer.

Canyonlands National Park

Although it’s the 23rd largest National Park in the US, Canyonlands is the largest out of the four national parks in Utah. The best time of the year to visit is when the weather is pleasant in the spring and fall. The park has four main parts: The Maze, Island in the Sky, The Needles, and Horseshoe Canyon. If you plan to visit every part, you can go on a boat tour to explore it.

Arches National Park

Known as a red-rock wonderland, Arches National Park is popular for its stone arches (石拱).The park has over 2,000 stone arches, with Landscape Arch the largest. The park is busiest from March through October. However, the spring and fall temperatures are the most comfortable. So, the best time to visit is April, May, September and October.

6 . If you are struggling with social anxiety, and don’t know how to find good friends, you can use the following important ways to meet new people.

    1    

A bookstore is a great place to get to know people with a true sense of curiosity. Meeting new people in the bookstore is lovely because your conversations have depth. You can talk about the different stories you’ve read.     2    .

Go traveling

Traveling is one of the most adventurous ways to meet other people. People will be in a good mood, particularly when traveling for a vacation, which opens up chances to meet new people in a happy way.     3    , you explore different places, and create positive memories while meeting new people from different cultures. You’ll make new friends during this happy moment in your life.

Attend a music festival

If you love songs, attending a music festival is the perfect choice for you. In this way, you really can’t escape meeting new people since you’re surrounded by hundreds or even thousands of people in one place, enjoying the live music.     4    . There’s a big chance that the people you meet in this event are connections you’ll remember even after it ends. If the event is several days long, you might notice that you go out with those strangers for a couple of days. After the event, you might choose to stay in touch.

Take a course

There’s no better way of making new friends and meeting people than taking a course. You can take a course such as learning a skill.     5    , you gain knowledge and a skill, and you get to socialize with a new set of people.

8 . Hidden in the trees, behind the leaves, look closely and you’ll see eyes staring back at you. This is SlothBot, a robot inspired by the famously slow animal-sloth (树獭).

For the next several months, visitors to the Atlanta Botanical Garden will be able to observe the testing of the new high-tech tool in the battle to save some of the world’s most endangered species. Researchers are testing the SlothBot near the Garden’s popular Canopy Walk.

Built to take advantage of the low-energy lifestyle of real sloths, SlothBot demonstrates how being slow can be ideal for certain applications. Powered by solar panels and using innovative power management technology, SlothBot moves along a cable strung between two large trees as it monitors temperature, weather, carbon dioxide levels, and other information in the Garden’s 30-acre midtown Atlanta forest.

“Slowness is a design principle of SlothBot,” says Magnus Egerstedt, professor and chair in the Georgia Institute of Technology’s School of Electrical and Computer Engineering. “That is not how robots are typically designed today, but being slow and energy-efficient will allow SlothBot to stay in the environment to observe things we can only see by being present continuously for months, or even years.”

About three feet long, SlothBot’s imaginative 3D-printed shell helps protect its motors, gearing, batteries and sensing equipment from the weather. The robot is programmed to move only when necessary, and will locate sunlight when its batteries need recharging.

“The most exciting goal we’ll demonstrate with SlothBot is the union of robotics and technology with conservation,” says Emily Coffey, vice president for conservation and research at the Garden. “We do conservation research on endangered plants and ecosystems around the world, and SlothBot will help us find new and exciting ways to advance our research and conservation goals.”

“SlothBot could do some of our research remotely and help us understand what’s happening with pollinators(传粉者), interactions between plants and animals,   and other phenomena that are difficult to observe otherwise," Coffey adds.
