“ Ask not what your country can do for you--ask what you can do for your country.” It's a famous quote from US president John F, Kennedy's inaugural(就职) speech in 1961.

    Mark Zuckerberg, the founder of the social networking site Facebook, must agree with Kennedy. The 33-year-old American donated $100 million to the public schools in New Jersey, US.

    Who is this young billionaire? How did he make his fortune?

    Thirteen years ago, Zuckerber was a computer geek(怪才) at Harvard University. As a second-year student, he set up a website to put the “face books” --photos of incoming first-year students online. The website, where people were able to share personal information, was a success at once.

    Zuckerberg first opened Facebook to high school students and then to everyone. Greeting such as “Have you checked your Facebook page today?” and “Do your ‘friends' know what you ate for breakfast?” became a part of American life. Now Facebook is the most popular site in the world with 1.7 billion users.” I could have never imagined all of the ways people would use Facebook when we were getting started thirteen years ago,” Zuckerberg wrote in a recent blog.

    Zuckerberg's dream is to make the Internet a more connected place. The mission(任务)could become profitable for Facebook. The more people share information about themselves online, the more money Facebook will make selting advertising. Zuckerberg is already worth $34 billion, according to Forbes.

    Yet the billionaire keeps his own life out of the public eye. At the company, it is said that he sits among a sea of desks like hundreds of workers. A visitor to Facebook might not even spot Zuckerberg in T-shirt and jeans. He usually takes one two-week vacation each year with his wife Priscilla Chan, a Chinese American. On the weekends, it is reported that he roasts pig and goat in his backyard for friends and takes Chinese lessons.

    The Social Network, a movie based on Zuckerberg's story, came out in 2010. It became one of the most popular films of that year.

    Last summer Jenny and her friends had a bus trip to New York. She felt very relaxing on the way. They visited a museum. But it's really crowded there and the display(展览) were not interesting at all. They went to different restaurants to have dinner. Some food was quite delicious, but Jenny thought the fast food was terrible. When the weather was fine, they went to the beach to swim. The sea was beautiful and they had a good time.

    An Englishman was showing a foreign visitor around London.“What's that strange building?” asked the visitor.“That's the Tower (塔) of London.”“I see. How long did it take to build it?”“About 500 years.”“In my country we can build it in a few months.”said the visitor. After they came to St. Paul's Cathedral (大教堂), the visitor asked the same question. “Nearly forty years,”said the Englishman. “In my country we finish it in forty days at most,” said the visitor. This went on all day. They visited most of the best known buildings in the city. Every time they saw a new one, the visitor asked what it was and how long it took to build it. Then he said they could do the same thing much faster in his country. At last the Englishman got angry with the visitor though he tried not to show it. Several days later they came to the House of Parliament (议会) and the visitor asked his usual question, “What's that?” The Englishman answered, “I have no idea. It wasn't there last night.”

    One day, I saw a boy shop alone at the shop I worked. He chose some school things he wanted and went to the checkout (付款台).

    The young shop assistant (店员) told him he needed to pay $37.60. The boy became very sad and said he only had $20. He took out one thing at a time, and at last he got down to his $20. With eyes full of tears, he asked if he could call his mom to pick him up. When he got through, it seemed that his morn was too busy to pick him up in a minute.

    He tried to stop the tears and walked outside to wait on the chair in front of the shop. This was too much for the young assistant. She kept looking outside to see if the boy was all right. Then she said, "I wish I could pay for the rest (剩余部分) of his  things." One of the other girls said she had a few  dollars. Then two others said they could help, too.

    These four young girls pooled their money and found they had more than enough to pay for the boy s things. Then they chose more school things, and gave them all to the boy. The boy laughed happily. His morn arrived much later, but he didn't just run to the car; he ran back into the shop and called out, "Thank you!"

    I was so proud (骄傲的) of my team that day. They did something wonderful for that boy and also found the pleasure (快乐) of giving.

    For one little boy, it was the coldest winter because his father had an accident and lost a leg. The whole family got into trouble.

    One night, while the boy was hanging out in a small shop, he saw some beautiful bags of coffee. Then he had an idea. He knew his father loved coffee and he also knew stealing wasn't good. But to make his father smile, the boy put a bag of coffee into his jacket and ran back home. His father smiled when he saw the coffee. But, unluckily, before his father could taste it, the shop assistant came and caught the boy. His father became so angry that he beat the boy.

    Years later, the boy became a successful businessman. One day, his mother called and said his father wanted to see him. The boy was busy, so he refused. Weeks later, he received the sad news that his father had died. When he checked his father's things, he found an old box. Inside it was the coffee that he had stolen from the shop. On the bag his father had written：

    "Dear son, I haven't been successful as a father. But I had a dream-to own a coffee shop. Then I could make cups of coffee for you. I'm sorry I didn't make my dream come true."

    The boy felt so sad. He felt guilty about not meeting his father for the last time, and decided to achieve his father's dream. After giving up his own business, he started a coffee business. The coffee business is now a huge success.
