“There's a mother in PICU(儿童重症监护病房)who wants to talk about a kit she received,” the nurse told me. “Something about it made her cry.”

    I've been a child-1ife specialist at the Cleveland Clinic Children's Hospital since 2000. I help families understand diagnoses and treatment plans and manage the ups and downs that come with caring for a sick child. Tough talks with parents are part of the job, which still makes me feel nervous.

    The kits the nurse was talking about were something I had recently introduced to the hospital: Comfort Kits from Guideposts. They were supposed to make a child's experience here easier, not upsetting.

    When I came across the kits at a conference. I fell in love with them. A treasure box of items designed not only to entertain kids, but to comfort and inspire them. There's a coloring book, a stress ball, a CD of relaxing music, a hairy star named Sparkle, a journal and much more. I really believed these kits would help kids. I wished I hadn't been mistaken.

    At the patient's room in PICU I saw a little girl, sleeping soundly, surrounded by tubes and machines. My eyes met her mother's. The kit was open on her lap and tears were running down her cheeks.

    “I'm Shannon. I manage the Child Life Department.” I said. “I'm sorry if the kit upset you .It's a new item…”

    The mother shook her head. “This has been one of the worst days of my life .I felt so scared and alone. Then I was handed this box. I know it's for my daughter, but it's just the comfort I needed. I wanted to say thank you.”

    With that I knew Comfort Kits belonged here. We've been using them for almost three years now. Each child who's admitted to the hospital receives one. Every day I see kids coloring, journaling, playing with Sparkle.

    But as this mom showed me Comfort Kits aren't just for kids. The hope they bring, which can be in short supply in hospitals sometimes, is felt by the whole family.

    We took a rare family road trip to the Adirondacks in late August，and it was as refreshing and exhausting as family vacations tend to be．Toward the end of our long drive home, even the kids were leaning forward in their seats urging my lead foot on．At that point in a road trip，even sixty-five miles per hour feels slow. We have become numb to our speed and numb to the road signs flashing by.

    My family lives on the edge of Lancaster County. Only thirty miles from home，I hit the brakes，and we began to roll，slowly，behind a horse-drawn carriage. We began to open our eyes again．We saw familiar green hills and the farm with the best watermelons. I rolled down the windows, and we breathed again．Just-cut hay and a barn full of dairy cattle．

    At five miles per hour，you remember what you forget at sixty-five．You are thinking about a place，even when you are moving from place to place．

    I am a placemaker. A homemaker, too. I am a mother of a young kid at home，and also a writer and a gardener．But，for me，those roles are wrapped up with the one big thing I want to do with the rest of my life：I want to cultivate a place and share it with others．

    The place I make with my family is a red-brick farmhouse built in l880. It has quite a few nineteenth-century bedrooms and a few acres of land，and we love nothing more than to fill them with neighbors and friends. We grow vegetables and flowers，keep a baker's dozen of egg—laying chickens，and，since we moved in three years ago，we have planted many，many trees．

    Living with my life's purpose does not allow for much travel. I need to be here，feeding the chickens and watering the tomatoes. Any extra in the budget，and we spend it on trees．

    But I learned something at the end of our family road trip．Travel can help me in the task of caring for my own place．When I slow down and pay attention to the road between here and there，travel tells me the connections between my place and all the other places．

    Have you ever noticed tiny raised areas on the branches of a tree? These may have been insects. These small insects feed on tree sap (汁液). Insects on urban trees are notably more abundant than those on rural trees. As a result, urban trees suffer from heavy infestations (害虫横行), and are often unhealthy or die. To protect and restore urban trees' health, we need to determine the factors that make these tree pests more successful in urban habitats.

    Living organisms interact closely with their environment. The warmer, more drought-stressed trees harbor more successful pests than cooler, less drought-stressed trees. As cities and natural habitats become hotter and drier, damaging insects will become more abundant on urban trees.

    Trees within urban forests are valuable economically and for the environmental sustainability (可持续性) of the region. More than half of the world's population lives in cities. Across the globe, people are moving into cities at a faster rate than ever. Rapid growth may turn cities into places with harder conditions. Although cities are primarily made of buildings, roads, parking lots, and vehicles, there are still plants in them. The trees within a city are referred to as the urban forest. Urban forests offer very big benefits to human and environmental health. They improve air and water quality, provide habitat for wildlife, cool down temperatures and beautify our environment. They make cities livable.

    However, being a city tree is not easy. Heat released by human activities is trapped in cities. As a result, temperatures in urban areas are often warmer than their surrounding rural areas. We call this urban warming or the urban heat island effect. Urban habitats are mostly made of surfaces of asphalt (沥青) and concrete. These surfaces reduce the amount of rainwater that reaches tree roots. As a result, urban forests may suffer, which can negatively affect people and the environment.

    What can we do to restore urban forests? Regular irrigation when possible may help keep pest populations under control. Planting tree species that are suitable to handle heat and drought stress would also reduce the occurrence of insect pest outbreaks.

    The Lumière Brothers had their film shows, taken over 100 years ago, to 100 paying customers on December 8, 1985. One of their earliest films was a 30-second piece which showed a section of a railway platform. As the train approached, panic started in the theatre: people jumped and ran away. In their confusion, the audiences feared that a real train was about to crush them. That was the moment when cinema was born.

    Early cinema audiences often experienced the same confusion. In time, the idea of films became familiar, the magic was accepted — but it never stopped being magic. Film has never lost its unique power to embrace its audience and transport them to a different world.

    One effect of this realism was to educate the world about itself. Cinema makes the world smaller. Long before people travelled to America or anywhere else, they knew what other places looked like and how other people worked and lived. Undoubtedly, in the lives recorded in film people knew more about American life. Hollywood has dominated the world film market. American imagery — the cars, the cities, the cowboys became the primary imagery of film. Film carried American life and values around the globe.

    And, thanks to film, future generations will know the 20th century more familiarly than any other period. We can only imagine what life was like in the 14th century or in classical Rome. But the life of the modern world has been recorded on films. We shall be known better than any preceding generations.

    The “star” was another natural consequence of cinema. The cinema star was effectively born in 1910. Because everybody in the world seems to know who they are, they appear more real to us than we do ourselves. The star as magnified human self is one of cinema's most strange and enduring legacies(遗产).

    Cinema films originally were planned as short stories, because early producers doubted the ability of audiences to concentrate for more than the length of a reel. Then, in 1912, an Italian 2-hour film was hugely successful, and Hollywood settled upon the novel-length narrative that remains the dominant cinematic convention of today.

    And it has all happened so quickly. Almost unbelievably, it is only 100 years since that train arrived and the audience screamed and fled, perhaps, suddenly aware that the world could never be the same again — that, maybe, it could be better, brighter, more astonishing and more real than reality.

    John George, 60, remembers that he lived a wonderful life in the Detroit neighborhood where he grew up. "We knew all our neighbors." George told Detroit's Metro Times. "On Christmas Eve, we'd all go to midnight Mass, and there'd be 300 people in our house at one o'clock to about five in the morning. The folks were just really good, hardworking people."

    By the'80s, however, the old neighborhood changed. Due in part to economic downturns and drug abuse, well -kept homes had been abandoned and kindly neighbors had fled to the suburbs(郊区). But not George. "Living in any city, it's like being in a relationship," he told Reader's Digest. "Some days are better than others. But it was my home. And when I saw it becoming worse, I had two choices: I could leave, or I could stay and fight. I chose the latter."

    When the abandoned home behind his turned into a worn-out place, the father of two grabbed some boards and nails and began boarding up the house. After two neighbors stopped to ask what he was doing, they decided to help, with great results.

    That's how it all got started. In the 30 years since that first home rescue, an army of approximately 182,000 volunteers, along with private donors, has helped George pull down around 300 abandoned homes, mainly in die poorer Northwest area of Detroit. They've also secured 400 - some homes by boarding them up. They've painted and repaired nearly 900 homes and built over 100 from scratch. According to Forbes, more than 1,000 Detroiters have been housed as a result of their work.

    And there's Halloween. In Detroit, October 30 was known as Devil's Night, a period when all hell break loose in the form of crime and vandalism (破坏公物). In response, George created a citizens' patrol(巡逻)that would take to the streets, keeping an eye on illegal behavior. He named it Angels' Night What began with 12 neighbors on patrol in 1990 has grown to more than 60,000 citywide.

    George's inspired ideas have not gone unnoticed by the city he loves. Others are buying into it. There's a trend of younger homeowners coming in.
