One of my first memories as a child in the 1950s was a discussion I had with my brother in our tiny bedroom in the family house in Bethlehem, Pennsylvania.

    We had heard in school about a planet called Pluto. It was the farthest, coldest, and darkest thing a child could imagine. We guessed how long it would take to die if we stood on the surface of such a frozen place wearing only the clothes we had on. We tried to figure out how much colder Pluto was than Antarctica, or than the coldest day we had ever experienced in Pennsylvania.

    Pluto, which famously was downgraded from a “major planet” to a “dwarf planet”(矮星) in 2006, captured our imagination because it was a mystery that could complete our picture of what it was like at the most remote corners of our solar system

    Pluto's underdog discovery story is part of what makes it so attractive. Clyde Tombaugh was a Kansas farm boy who built telescopes out of spare auto parts, old farm equipment and self-ground lenses. As an assistant at Lowell Observatory in Flagstaff, Arizona, Tombaugh's task was to search millions of stars for a moving point of light, a planet that the observatory's founder thought existed beyond the orbit of Neptune. On February 18, 1930, Tombaugh found it. Pluto was the first planet discovered by an American, and represented a moment of light in the midst of the Great Depression's dark encroachment(入侵).

    Pluto is much more than something that is not a planet. It's a reminder that there are many worlds out there beyond our own and that the sky isn't the limit at all. We don't know what kinds of fantastic variations on a theme nature is capable of making until we get there to look.

    Sandra Cisneros was born in Chicago in 1954 to a Mexican American family. As the only girl in a family of seven children, she often felt like she had "seven fathers ", because her six brothers, as well as her father, tried to control her. Feeling shy and unimportant, she hid herself into books. Despite her love of reading, she did not do well in elementary school because she was too shy to participate.

    In high school, with the encouragement of one particular teacher, Cisneros improved her grades and worked for the school literary magazine. Her father encouraged her to go to college because he thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the University's Writers' Workshop, however, she felt lonely—a Mexican American from a poor neighborhood among students from wealthy families. The feeling of being so different helped Cisneros find her "creative voice".

    "It was not until this moment when I considered myself truly different that my writing acquired a voice. I knew I was a Mexican woman, but I didn't think it had anything to do with why I felt so much imbalanced in my life, but it had everything to do with it! That's when I decided I would write about something my classmates couldn't write about."

    Cisneros published her first work, The House on Mango Street , when she was twenty-nine. The book tells about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been used in classes from high school through graduate school level. Since then, Cisneros has published several books of poetry, a children's book, and a shortstory collection.

    Winter sports tend to be more dangerous than summer sports — they take place mostly outside at the mercy of ice or snow, involving (牵涉) metal edges, extreme speeds and crashes. Skeleton (俯视冰梭), however, stands apart as one of the most difficult and least accessible of all the winter sports. Adam Edelman, Israel's first Olympic skeleton athlete, would like to change that.

    Edelman was the 10th athlete named to the 2018 Israeli Olympic Team. Qualifying for the Olympics in any sport is impressive. But it's more impressive if you qualify for the Olympics after only four years in the sport — and without a coach.

    Edelman was first introduced to skeleton watching the game on television in late 2013. Sports have always been a part of his life. He grew up playing football and was a goalkeeper on the Massachusetts Institute of Technology football team. Ready for a new challenge, he set his sights on the Olympics.

Without a coach, Edelman learned to drive by watching endless hours of YouTube videos and taking more runs than anybody else on the track. “When everybody else would take three runs per day, I would take six to eight.” he recalled.

    Succeeding in skeleton takes a large amount of athletic ability and technical skill, but there's one more element (因素) required, one that can't be taught. “These tracks but built in the middle of nowhere, and it's gray and cold. You haven't seen your family in seven months and you really just want to give up. To continue, it takes tenacity.” Edelman said.

    Edelman is already looking beyond Pyeongchang. The 2022 Olympics could be in his future, but whether he continues to compete or not, he promises to stay in Israeli sports as long as possible-as instructor or as a coach.

    What to do if you find a sick, injured or abandoned wild animal.

    General tips

    Don't remove an animal from its natural habitat (the animal may not need assistance, and you could do more harm than good).

    Check the animal periodically for 24-48 hours.

    Keep your distance.

    Young animals/babies

    If you find an abandoned young animal, separated from adults or left on its own — keep cats and dogs away and limit noise.

    An adult may not return if it is noisy or if people are close by.

    Get help for a wild animal

    In Ontario, wildlife rehabilitators (复健员) are authorized by the Ministry of Natural Resources and Forestry to provide temporary care to sick, injured and abandoned wildlife so it can be returned to the wild. Rehabilitators commit significant time and resources, and many seek donations to assist with their work.

    Every effort is made by wildlife rehabilitators to ensure wildlife in their care do not become tame (驯服).

    Find a wildlife rehabilitator

    To get help for a sick, injured or abandoned animal, you can contact: an authorized wildlife rehabilitator your local Ministry of Natural Resources and Forestry district office

    Health risks

    If you come across sick or diseased wildlife and you suspect there is a public health risk (such as West Nile virus), contact your regional or local health unit immediately: Ontario Public Health Units

    Public safety

    If the animal is alive and there is a public safety issue, contact your local police department.

    Maybe it's because it was our first purchase as homeowners. The salesman must have spotted just how green we were, so he began persuading. And soon he led us to a classic leather chair. All these years later, I remember he used words like rich and handsome, the thing every living room needed.

    We believed him. So we bought that chair — just less than $100, a great deal in the 1970s for a young couple!

    How we loved that chair! It always occupied a place of honor in our various living rooms, moving with us from our first tiny house to our beloved new house.

    Somehow, conversations were better on that chair, and life was more fun around it. Three daughters spilled their secrets on it. Old friends seemed to be attracted by it on those wonderful occasions. Crazy as it sounds, that leather chair seemed to have — well, powers. All for good.

    At first, we didn't really care that the leather was showing signs of wear or that it had lost its sheen (光泽). But in our most recent move, when the chair was moved in our new living room, it suddenly looked terribly lonely sitting close to newly painted walls and a couple of shiny new tables.

    My husband and I tried but still we couldn't ignore the rough spots. Our chair had a skin disease. Even our adult kids raised eyebrows, urging us to at least remove the chair to some dark comer of the room. Neither of us could imagine such a retirement for it.

    So we had an inspired idea. We'd call in an upholsterer (修理工) to give our old chair a whole new life. Our friend Joe studied the chair and then took out a simple leather conditioner. He explained that although it wouldn't work miracles, it would definitely get our weary chair looking younger again. It certainly doesn't look new, but its seat and back are shining, and some of its deeper wrinkles have lightened.

    Best of all, it's back in the living room, looking like a wise old friend to the furniture around it. And, yes, there it will stay.

    Because some things, like some people, just deserve a happy old age.

Last August, the 900-year-old Wan'an Bridge in Pingnan County, a locality of Ningde City in the coastal Fujian province, was destroyed when it suddenly caught fire.

Wan'an, a national-level protected building, was a wooden arch corridor bridge (木拱廊桥),which for centuries was an ancient architectural calling card for the region. The bridge,98.2 meters long and 4.7 meters wide, was first built in the Song dynasty (960~1279), and was the longest wooden arch corridor bridge left standing in China. Few, however, had imagined that such an ancient bridge would attract public attention in such a way.

Amid the powerful voice of the local population for new wooden arch bridges, the traditional techniques behind the building work have well and truly been revived (唤醒), but the protection of the ancient buildings still has much room for improvement.

Currently, China's approach to the protection of national heritage sites puts protecting and rescuing endangered buildings before all else, but to keep these ancient buildings alive, preventive protection is key.

"Technically, restoring (修复) Wan'an isn't very difficult," said Li, Deputy County Mayor of Pingnan. "Along with the help of the local inheritors of the national intangible cultural heritage, the bridge's restoration looks hopeful. However, the historical value will definitely be affected."

Meanwhile, Zhan, the former Deputy Dean at the Chinese Academy of Cultural Heritage, pointed out the recent destruction of Wan'an Bridge highlights a serious shortage of warning mechanisms and preventative protection measures, which currently are supposed to be the most important part of protection. "Significant improvements have been made in the past few years in protection, but we still have a long way to go on proper planning for protection work. How to protect cultural heritage is a matter that we need to discuss as soon as possible," he added.
