    Zhang Lili, a Chinese language teacher at No.19 Middle School of Jiamusi in Heilongjiang Province, has recently been considered to be "the Most Beautiful Teacher" in China.

    At 8: 38 pm on Tuesday, May 8^th, 2012, Zhang Lili and her several students were waiting for a bus at the school gate when suddenly a school bus lost control and rushed towards them. When she realized the danger, she pushed two students to safety, but she was hit and run over. The 29-year-old teacher lost her legs.

    "She is a backbone(骨干) teacher in our school. She works very hard," said the headteacher.

    The heroic teacher was the most popular teacher among the students. "Her students love her a lot. Her room is always full of students when she is free," said another teacher.

    Zhang Lili was also very generous. "My son has lost his father. Every month, Zhang secretly put 100 yuan in his desk from her own salary(工资) to support his studies," said a boy's mother, who was waiting outside the emergency room(急诊室) for hours to express how grateful she felt towards Zhang.

    Two weeks later, Zhang Lili came out of her coma(昏迷). She wrote a letter to her students, wishing them good luck on their entrance exams for high school. Her letter, 200 words long took her three days to write.

    The following are some tips for becoming a successful businessman by Michael Bloomberg. They are based on his experience of building a company from the ground  up, leading New York City as mayor（市长）, and so on.

Take Risks

    Life is too short to spend your time avoiding failure.

    In 1981, at the age of 39, I lost my job. The next day I took a big risk and began my own company. In 2001, when I was debating whether to run for mayor, most people advised me not to do it. But one person said, “If you can imagine yourself giving a concession（败选）speech, then why not go for it?” That was the best advice I received, and I followed it.

    In order to succeed, you must first be willing to fail— and you must have the courage to go for it anyway.

    Make your own luck

    Luck plays a part in success. The harder you work, the luckier you get.

    Whatever you choose to do, even if it's not the job of your dreams, always work hard at it. Be the first person at work in the morning and the last to leave at night. Hard work creates chances.

    Never stop learning

    The most powerful word in English language is “why”. There is nothing so powerful as an open, inquiring mind（探究精神）. Whatever field you choose for starting a business — be a lifelong student.

    Give back

    You are responsible for your success and failure, but you only succeed if you share the reward with others.

    My first donation was a $ 5 check to my alma mater （母校） . And while the checks（支票）may be bigger today, they come with the same spirit.

    You don't have to be wealthy to give back. You can give back by giving your time and talents.

    A'Layah Robinson lives in Oklahoma, USA. She is only seven years old, but already she has big ideas for helping other kids!

    One Saturday morning when A'Layah was five, she noticed some teenagers who had a lemonade stand(柠檬饮料摊位). They wanted to raise money to help some of their friends. A'Layah wanted very much to help kids too, especially foster kids(寄养儿童)! You see, A'Layah and her brother were both foster kids. The little girl's birth mother was a drug addict (吸毒成瘾者), so she was taken to a foster care centre. Luckily, she finally found a forever home in the Robinson family.

    But A'Layah still couldn't forget the day when her brother came to live with them. She felt sad that he only had old clothes and shoes that were too small. She thought maybe she could help with a lemonade stand! That way she could raise money so that other foster kids could have a toy and a few other things of their own.

    A'Layah's first lemonade stand made $132! A'Layah was so excited to go with her mother to buy things for the foster kids. She decided they should have a toy, a toothbrush, a blanket and a book. Her first donation(捐赠物) was for 24 kids!

    A'Layah wanted to help more kids, so her mum helped her start a charity called A'Layah's Lemonade for Love. Till now, it has already raised over$17, 000! A'Layah hopes someday she will be able to send a toy to every kid in foster care.

Tom and Mike were good friends, and they began to work in a company together the same year. They both worked hard. After several years, however, the boss made Mike manager (经理) but Tom was still an office worker. Tom couldn't stand it, so he handed a letter to his boss, saying that he decided to resign (辞职) his job because the boss didn't value his hard work at all.

The boss knew that Tom worked very hard for years. He thought for a moment and said, "I hope you will do one more thing for our company before you leave. Perhaps you will change your mind." Tom agreed. The boss asked him to go and find out if there was anyone who sold water-melons in the market. Tom returned soon. He said he had found a man selling watermelons. The boss asked the price of the watermelons. Tom shook his head and went back to the market again. When he returned, he told the boss it was $2 for each kilo.

The boss told Tom to wait for a moment in his office, and he called Mike in. He asked Mike to find if there was anyone selling watermelons in the market. Later Mike returned and said, "Only one man is selling watermelons, $2 for each kilo. He has 100 watermelons in all. Every watermelon weighs about 2 kilos. They were brought here two days ago, pretty fresh and sweet." Tom got to know the difference between Mike and himself. He decided not to resign his job any more.
