    Winters are long and unforgiving in North Dakota. The winter of 1996 was especially brutal. It was a hard time in my own life too. A neck injury had kept me flat in bed for nearly a year. “Just in time for Easter,”my husband, Dick, said. But how could I feel the joy when the snow was four feet deep and I had months of painful physical treatment ahead?

    I was doing the dishes one day, feeling hopeless when there was a tap against the glass. It was a branch of the troublesome cottonwood (棉白杨).Back in the fall of 1979, it was a new subdivision (分支）then, an eight-foot stick. The people who'd briefly occupied the house before us had placed the pipe from the pump next to it. The earth was so wet that the poor thing had fallen down, most of its bare root system pointing skyward, and blowing hopelessly back and forth in the cold wind. Dick decided to pull it out one day, but I protested.

    “Look at how hard it's trying!” I said, pointing to the way it strongly kept hold of the earth. “It deserves a chance.”

     Dick borrowed some tools. We packed dry soil around the tree and put up some stakes (桩) into the ground, making it stand upright. That winter was still terrible. Surprisingly,in the spring my “rescue stick”put forth a few leaves,then with lots of branches. The year after that, we were able to remove the stakes. By the 1990s that little stick was a giant, towering over the house.

    Now the tapping at the window continued, louder as the wind picked up, almost as though to tell me to look up. At last, I did. I caught my breath. In the window against the icy blue sky, thousands and thousands of fresh red buds were waving in the wind.

    The tree was bursting with life and I had a wonderful Easter.

    What is eBay? The simple answer is that it is a global trading platform(贸易平台) where nearly anyone can trade practically anything. People can sell and buy all kinds of products and goods, including cars, movies and DVDs, sporting goods, travel tickets, musical instruments, clothes and shoes—the list goes on and on.

    The idea came from Peter Omidyar, who was born in Paris and moved to Washington when he was still a child. At high school, he became very interested in computer programming and after graduating from Tufts University in 1988, he worked for the next few years as a computer engineer. In his free time he started eBay as a kind of hobby, at first offering the service free by word of mouth. By 1996 there was so much traffic on the website that he had to upgrade(升级) and he began charging a fee to members. Joined by a friend, Peter Skill, and in 1998 by his capable CEO, Meg Whitman, he has never looked back. EBay has gone from strength to strength. It is now one of the ten most visited online shopping websites on the Internet.

    eBay sells connections, not goods, putting buyer and seller into contact with each other. All you have to do is make an e-photo, write a description, fill out a sales form and you are in business: the world is your market place. Of course for each item sold eBay gets a percentage and that is great deal of money. Every day there are more than sixteen million items listed on eBay and eighty percent of the items are sold.

    Mother Teresa (August 26, 1910-September 5, 1997) was a great woman, who did a lot to improve the social condition of mankind. Due to her contribution in serving the society, she was awarded the Nobel Peace Prize aged 69.

    She was brought up in a Catholic family. When she was only seven, she lost her father. Even as a young child, she was interested in the life of missionaries (传教士). At the age of 18, she decided that she would become a nun. She left her home and went to join the Sisters of Loreto. It was the first step that she made towards providing services for mankind.

    On the 7th of October in the year 1950, Mother Teresa received Vatican permission to start the Missionaries of Charity in Calcutta, the mission of which would be to take care of the needy, the homeless, and people who were shunned by the society. Then it had a number of branches all over the country. The journey of Mother Teresa's Missionaries of Charity started with the setting up of homes for "the Dying".

    In the year 1983, Mother Teresa suffered from a serious heart attack, while she was in Rome. However, she recovered. But, later in 1989, she again got an attack. Her health went worse and in the year 1991, she suffered from pneumonia. Taking her health problems into consideration, Mother Teresa decided to resign (辞职) from the post of head of the order.

    A secret vote was conducted in which all the nuns voted for the stay of Mother Teresa except herself. So, she agreed to continue serving as head of the Missionaries of Charity. Day by day her health was getting worse. On September 5, 1997, exactly nine days after her 87th birthday, this great soul departed for heaven.

    Although small business training and credit programs have become more common throughout the world, little attention has been paid to the need of young people, and even less to the children living on the street or in difficult condition.

    Over the past nine years, Street Kids International (S.K.I.) has been working with partner organizations in Africa, Latin America and India to support the economic lives of street children and develop opportunities for street children to earn income.

    The S.K.I. Bicycle Courier Service first started in the Sudan. Street children who took part in it were given bicycles, which they used to deliver parcels and messages. A similar program was taken up in Bangalore, India. The Shoe Shine Collective was a program with the Y.W.C.A. in the Dominican Republic. The children in this project were lent money to buy shoe shine boxes. They were also given a safe place to store their equipment, and facilities for individual savings plans. The Youth Skills Enterprise Initiative in Zambia is a program with the Red Cross Society and the Y.W.C.A. Street youths are supported to start their own small business through business training, life skills training and access to credit.

    During the program, The S.K.I. and partner organizations have drawn lessons from the past: First of all, being a businessman is not for everyone, nor for every street child. And it is important for all loans to be linked to training programs that include the development of basic business and life skills. Secondly, small loans are provided firstly for buying fixed assets such as bicycles, shoe shine kits and basic building materials for a market stall. As the children gain experience, they can be given more loan amounts. And all S.K.L. programs have charged interest on the loans. Generally the rates have been lower than bank rates. Most importantly, it is believed that credit must be given with other types of support that help the young develop key life skills as well as productive businesses.
