“Community” is not a concept that is easy to define (定义) . In this essay I will examine what turns individuals into a community, and discuss some different types. I will also look at what all communities have in common, the benefits they offer and draw conclusions about their increasing importance.

    The word “community” may make you think of traditional communities in the developing world, where large families live together. We may also imagine the neighbours as people who are happy to help out whenever it is needed. The stereotpical(老套的) view is that of a village, where people have little but can feel very rich because everyone takes responsibility for the welfare of the others.

    On the other hand, there are other types of communities: ultramodern(超现代的) ones, where the community members are unlikely to have actually met each other. These are online communities, where people blog or chat about particular issues that are important to them. They come across others on websites and may develop a relationship there with like-minded people, discussing the same topics. The view is often that these are artificial connections between people who are, in effect, still isolated(孤立的) strangers.

    In reality, the connections are real. Moreover, there are many types of communities in between these extremes: people who join clubs, who sign up with voluntary, political or other organizations, or who take part in group discussions in their local area. They may be campaigning about issues or simply getting together for companionship and support.

    Human beings are social by nature, so it should not be a surprise that we organize ourselves in groups. However, there is more going on: these groups provide something that we cannot achieve on our own. The main benefit of being part of a larger group is strength in numbers. For example, we can access and share more information, we can take part in team sports, we can complain and campaign more effectively and even if we are just having a chat, online or in person, we can feel supported in whatever we do.

    Whatever forms communities take, what defines them is the sense of identity and safety that they provide for their members: the knowledge that there are people who we have something in common with and who can be relied on when we need each other.

    My family lived in a motel for two years. Like most families living there, we stayed in a two- bedroom suite. We were living from paycheck to paycheck, so when Christmas approached, we didn't know if we could be able to purchase gifts for our children.

    A few days before Christmas someone dropped off presents for all the kids that lived in the motel. It brought so much joy to all the children, most of whom knew that they wouldn't be receiving anything.

Five years ago, we moved out of the motel. After that, my husband and I were working hard at the Joe's Crab Shack to support our family. A few days before Christmas, I was working a “big top” and a single table. The man at my table could see that the large table was taking most of my time, but I was very patient and friendly. Between drinks and food I was able to chat with him about his family and mine. He left me $10, then walked out. About 10 minutes later, I turned around and there he was again. He gave me a hug, and put something in the side of my coat, telling me “Have a Merry Christmas”. I reached into my coat and pulled out $800.

    I was so moved by his generosity that I burst into tears. He had given me more than enough money to help my family catch up on our bills. After discussing what we should do with the money we had left over, we decided to buy presents for the families living at the motel, so we could pass on the blessing that we had received. Since then, it has been a tradition for us to give Christmas gift to the families in need.

    Last year we were able to give presents each of the 80 children at a school in our community, and throw a Christmas party for them. This year our goal is to add at least 20 children.

    Thanksgiving Day is a special holiday in the United States and Canada. Families and friends gather to eat and give thanks for their blessing.

    Thanksgiving Day is really a harvest festival. This is why it is celebrated in late fall, after the crops are in. But one of the first thanksgivings in America had nothing to do with a good harvest. On December 4,1619, the Pilgrims from England landed near what is now Charles City, Virginia. They knelt down and thanked God for their safe journey across the Atlantic.

    The first New England Thanksgiving did celebrate a rich harvest. The Pilgrims landed at what is now Plymouth, Massachusetts, in 1620.They had a difficult time and the first winter was cruel. Many of the Pilgrims died. But the next year, they had a good harvest. So Governor Bradford declared a three­day feast (盛宴).The Pilgrims invited Indian friends to join them for their special feast. Everyone brought food.

    In time, other colonies (殖民地) began to celebrate a day of thanksgiving. But it took years before there was a national Thanksgiving Day. During the Civil War, Sarah Josepha Hale persuaded Abraham Lincoln to do something about it. He proclaimed (宣布) the last Thursday of November 1863 as a day of thanksgiving.

    Today, Americans celebrate this happy harvest festival on the fourth Thursday in November. Canadians celebrate Thanksgiving Day in much the same way as their American neighbours. But the Canadian Thanks­giving Day falls on the second Monday in October.

    A layover (临时滞留) or flight delay can be extremely fun in these international airports.

Munich Airport, Germany

    Aviation (航空) lovers passing through Munich can take a behind－the－scenes tour to learn how the airport operates. Visitors can also tour three historic aircraft and a retired rescue helicopter, climb up to a 28－metre high observation platform for an up－close view of take－offs and landings, and watch films on aviation in the airport's 60－seat cinema. Travelers can also kill layover time at an 18－hole mini－golf course, or even stop in for a teeth cleaning at the airport dental office.

Changi Airport, Singapore

    After a long flight to Singapore, travelers can relax in a Balinese－style swimming pool, work out at the airport gym, or enjoy a drink and live musical performances at the airport's Music Bar. The airport also boasts a tranquil butterfly garden, and a “fragrant garden” which is home to 15 species of plants and trees. Free movies at one of two airport cinemas also keep passengers entertained.

    Schiphol Amsterdam Airport, the Netherlands

    Schiphol is Europe's fifth－largest airport. Here passengers can view the works of Dutch masters free of charge, and try their luck at airport's casino (赌场). You can even have your wedding ceremony at Schiphol—couples can choose from four different wedding packages, including a 1930－style ceremony held on a Dakota military aircraft.

    San Francisco International Airport, California

    The airport's 24－hour AirTrain not only moves passengers between terminal, but also provides a fun view of the runways. There are three aquariums (水族馆) to explore, along with interactive play areas, an aviation museum, and a library. If that's not enough to keep the little ones busy, travelers can rent portable DVD players and movies for use in the airport.

    A great woman once said, “Women must try to do things as men have tried. When they fail, their failure must be a challenge to others. “These are the words of US pilot Amelia Earhart（1897- 1937）, a pioneer in aviation（航空领域）, who was the first woman to fly across the Atlantic Ocean

    Her story ended in mystery when she disappeared without a trace（踪迹）during a flight over the Pacific Ocean. Theories about what happened to Earhart were proposed, but nothing was ever confirmed—until now. A study published in March conducted by Richard Jantz from the University of Tennessee, US, determined that bones found in 1940 on a remote Pacific island belonged to Earhart. Following the discovery, the world's memories of the legendary female pilot were brought back to life.

    Earhart was born in 1897. When she was young, she was very interested in stories about women who were successful in male-dominated（男性为主的）professions, such as engineering and law. But in 1920, Earhart's life changed after her first experience of being a plane passenger. As soon as the plane left the ground, Earhart knew that she loved flying, so she found herself a teacher and started to learn how to fly for herself. To pay for the lessons and buy a plane of her own, she took all sorts of jobs.

    In 1932, Earhart flew solo（独自地）across the Atlantic, becoming the first woman ever to do so. She also designed a flying suit for women and went on to design other clothes for women who led active lives. When she was nearly 40, Earhart was ready for a final challenge—to be the first woman to fly around the world. Her first attempt was unsuccessful but she tried again in 1937 with her navigator（领航员）Fred Noonan. But one month later, they disappeared in bad weather in mid-flight.

    Even though it's still not clear how she ended up on the island, we're one step closer to finding the answer. And no matter what, Earhart will be forever remembered as a brave pioneer, both as a pilot and as a woman.

    The Healthy Habits Survey (调查) shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    ①How many times did you brush your teeth yesterday?

    ·Finding: A full 33% of seniors brush their teeth only once a day.

    ·Step: Remove the 300 types of bacteria (细菌) in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

    ②How many times did you wash your hands or bathe yesterday?

    ·Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number doctors recommend.

    ·Step: We touch our faces around 3, 000 times a day—often inviting germs (病菌) to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

    ③How often do you think about fighting germs?

    ·Finding: Seniors are not fighting germs as well as they should.

    ·Step: Be aware of germs. Do you know it is not your toilet but your kitchen sponge (海绵) that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.
