First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. It may save a life or improve certain vital signs including pulse, temperature，a clear airway(气道), and breathing. In minor emergencies，first aid may prevent a victim's condition from turning worse and provide relief from pain. First aid must be   administered as quickly as possible. In the case of the Critically injured, a few minutes can make a difference between complete recovery and loss of life.

    First­aid measures depend upon a victim's needs and the provider's level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example，can lead to permanent spinal (脊柱的) injury and  paralysis (瘫痪)．

    Despite the variety of injuries possible, several principles of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious（有意识的）, should be reassured that medical aid has been requested，and asked for permission to provide any first aid.  Next，assess the scene, asking other people or the injured  person's family or friends about details of the injury or illness，any care that may have already been given, and preexisting conditions such as diabetes (糖尿病) or heart trouble. The victim should be checked for a medical bracelet (手镯) or card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury，do not move the victim.

    First aid requires rapid assessment of victims to determine whether life­threatening conditions exist. One method for evaluating a victim's condition is known by the acronym(首字母缩写词)ABC，which stands for：

    A—Airway: Is it open and clear?

    B—Breathing: Is the person breathing? Look, listen, and feel for breathing.

    C—Circulation: Is there a pulse? Is the person bleeding externally? Check skin color and temperature for additional indications of circulation problems.

    A European Union program is letting blind people experience famous paintings for the first time. It uses three dimensional (3-D) printing to re-create famous paintings so they can be touched.

    One painting printed with the new technology is Gustav Klimt's “The Kiss.” It is a popular attraction at the Belvedere Museum in Vienna, Austria. The painting shows a man and a woman standing in a field filled with flowers. They are wearing gold robes and have their arms around each other. The man leans down to kiss the woman.

    Klimt finished the painting in 1908. Until now, people who had trouble seeing could not appreciate the artwork. But thanks to the reproduction they can touch the piece and feel the ridges and depressions. Andreas Reichinger started making 3-D versions of artwork in 2010. He said this reproduction was his most difficult project because the couple's robes are so detailed.

    Dominika Raditsch is a blind museum visitor. She touched the reproduction. As she moved her hands around it she said, ”Exactly, can you see these? There are so many details.“ Raditsch said she can imagine what the original painting looks like when she touches the reproduction. “It's somehow round. You can feel it. It comes with it. And in many places it's so smooth. And then I think to myself: it probably shines too!” Raditsch said.

    The Belvedere is not the only museum to have 3-D versions of its artwork. Some of the pieces at the Prado, in Madrid, Spain, have reproductions that can be touched. But the piece in Vienna has one special part: it is made with widely available 3-D printing technology. That means one day, blind art fans anywhere in the world could download the source files and print the reproductions themselves.

    In university I had a part-time job at a shop that sold doughnuts and coffee. Situated on a block where several buses stopped, it served the people who had a few minutes to wait for their bus.

    Every afternoon around four o'clock, a group of schoolchildren would burst into the shop, and business would come to a stop. Adults would glance in, see the crowd and pass on. But I didn't mind if the children waited for their bus inside. Sometimes I would hand out a bus fare when a ticket went missing — always repaid the next day. On snowy days I would give away some doughnuts. I would lock the door at closing time, and we waited in the warm shop until their bus finally arrived.

    I enjoyed my young friends, but it never occurred to me that I played an important role in their lives — until one afternoon when a man came and asked if I was the girl working on weekdays around four o'clock. He identified himself as the father of two of my favorites.

    "I want you to know I appreciate what you do for my children. I worry about them taking two buses to get home. It means a lot that they can wait here and you keep an eye on them. When they are with the doughnut lady, I know they are safe." I told him it wasn't a big deal, and that I enjoyed the kids.

    So I was the Doughnut Lady. I not only received a title, but became a landmark.

    Now I think about all the people who keep an eye on my own children. They become, well, Doughnut Ladies. Like the men at the skating rink (滑冰场) who let my boys ring home; Or the bus driver who drove my daughter to her stop at the end of the route at night but wouldn't leave until I arrived to pick her up; Or that nice police officer who took pity on my boys walking home in the rain when I was at work — even though the phone rang all the next day with calls from curious neighbors. "Was that a police car I saw at your house last night?"

    That wasn't a police car. That was a Doughnut Lady.

    If you frequently travel for business, Staybridge Suites offer you a range of home comforts. Four recent visitors to Staybridge Suites explain why they booked, what they enjoyed and what made them want to return.

Claire Metcalf

    "The concept is great, but the staff are the ones who really make it." she says. "It takes a lot of discipline to always be friendly, but the staff at Staybridge Suites do that. They genuinely care about you. "

Andrew Roberts

    "One of the best things is having my own kitchen. I often end up working late and I don't fancy eating in a restaurant on my own, so cooking for myself is a big drawcard. "

    "The main thing for me is being able to cook and have my own little flat. The staff are amazing. It is great to be recognized by them, "he says.

Pauline Robinson

    "What I love about it is the way that you are treated by the staff," she says. "Some of the staff have been there all that time and they do look after you well. As a woman staying on my own, it is reassuring that they look out for you, and recently when I was poorly depressed they even brought things I needed to my room. "

Ryan Ruckledge

    "The fully-equipped kitchen is great. I always have a one-bed apartment so I have a separate kitchen and dining room and I'm able to relax and cook some meals. Eating out can feel a bit much when you do it day in and day out—it makes you hate what you do—and I don't want that. "

    If you think American cooking means opening a package and throwing the contents into the microwave oven (微波炉), think again. On the one hand, it's true that many Americans have cold cereal for breakfast, sandwiches for lunch and instant (方便的) dinners. From busy homemakers to working people, many Americans enjoy the convenience of fast food that can be ready to serve in 10 minutes or less. On the other hand, many Americans realize the importance of cooking skills. Parents—especially mothers'—see the importance of training their children—especially daughter's. Most Americans think that there's nothing better than a good home-cooked meal. But with cooking, as with any other skill, good results don't happen by accident.

    Probably every cook has his or her own way of cooking. But there are some basic skills that most people follow. For example, baking is a main method of preparing food in America. For that reason, Americans would find it next to impossible to live without an oven. American cooks pay special attention to the balance of foods, too. In planning a big meal, they try to include meat, a few vegetables, some bread and often a dessert. They also like to make sure the meal is colorful. Having several different colors of food on the plate usually makes for a healthy meal.

    For those who need guidance in their cooking, or for those who have just run out of ideas, recipes are a great help. Recipes list all the ingredients for a dish (generally in the order used), the amount of each to use, and a description of how to put them together.

Recently, my dad and I decided to take a day trip to the Florida Keys, a coral cay archipelago located off the southernmost coast of the US. I was super excited because I had not been able to go anywhere within the past nine months because of COVID-19.

With masks and hand sanitizer, we began our fun journey before sunrise. The Keys are about two hours away from where I live in Florida, so we would get there early to see the sun coming up over the ocean. On the road, we got to enjoy the Gulf of Mexico on one side and the Atlantic Ocean on the other.

When we stopped by Curry Hammock State Park, I was really amazed. The park contains 1,000 acres of land, which protects mangroves, rock land and seagrass beds that are important to the ecosyst (生态系统) in the Keys. During our time there, we were able to see some hawks flying by, and they followed the Gulf coastline of the Caribbean, migrating (迁徙) from Canada and as far south as Peru. These hawks put their wings out, "floated" up in the wide sky and then glided for long distances. After flying for thousands of miles, they still kept their fast flight patterns.

After that, we went to Key West and visited some iconic (标志性的) stops, like Duvall Street and Mile Marker 0. It was really cool because it is the very beginning of US 1, which is the longest road that runs from Key West to the Canadian border.

It was an amazing trip to the Florida Keys, and it was thrilling to have a change of scenery.
