 In 2015, on a TV show I Am a Singer 3, Li Jian became the most popular one, because he has great singing ability and sense of humor. Li has a smooth voice. His songs can really touch the listeners. People even give him the nickname "Poetic Musician" because of his poetic lyrics.

 Li was born in Harbin in 1974. He showed great talent for music from an early age. He learned to play the guitar by himself. Later, he became a good guitarist and won the first prize in a national competition. “In my younger days, guitar was like my best friend." Li said.

 Though he studied electronic engineering in Qinghua University, he never gave up music. Then in March 2001, Li formed a group called Shuimu Nianhua with his friend. Later, Li didn't agree to change their musical style. So the pair went their separate（分离）ways next year.

 Unlike some other musicians, Li does very few interviews or concerts. He spends more time writing songs. "Writing songs is like collecting water in a cup. When the cup is full, the water will come out naturally." he said.

    Mark Twain was a great writer in America. He wrote many books. He liked telling jokes in his books. People liked reading them very much. And it was full of jokes in his life, too. Mark Twain liked reading. So he often borrowed books from other people. One day, he wanted to borrow a book from his neighbor. His neighbor was a mean man. He didn't want to lend it to Mark Twain. Then he had an idea. He said to Mark Twain, “I have a rule. You will have to read the book at my home. If you want to borrow it from me, you should never take it out." Mark Twain had to read that book at his neighbor's house.

    A month later, his neighbor went to borrow a cropper (割草机) from Mark Twain. Mark Twain said to him with a smile, "I make a rule, too. That is, you must use my cropper in my garden. If you borrow it, you can never take it out either."

    A 50-year-old American officer(官员)came back to his school. The teacher asked him to give a talk to the small boys and girls there. The talk was about the love of their great country. All the little ones were sitting in a large meeting-room. The old officer went up and began speaking. He said, "Boys and girls, I studied in the school forty years ago. When l was your age, we were not as happy as you are today. Think about it and answer me, why are you so happy now?"

    No sound came from the children. The old marl waited for a long time. Then a short boy in the front put up his small dirty hand. "Good boy! Please answer me, dear, "said the officer.

    With a big smile on his face, the boy stood up and said. "If you speak long enough, we won't have math and biology(生物)lessons this morning."

    Yasutaro Koide, the world's oldest man, died at the age of 113, in Nagoya, Japan on January 19, 2016. But along with his many years, Koide also left us with a piece of advice for a long and fruitful life.

    Koide was born on March 13, 1903. He learned sewing and worked as a tailor(裁缝) for a men's clothes shop in most of his life. He moved to live with his daughter when he was 107 years old. When he turned 110, Koide could still read newspapers without glasses and could eat well without dentures(假牙). In August, 2015, Guinness World Records confirmed(认证) that he was the world's oldest man.

    Koide always loved sitting in front of his sewing machine, enjoying making all kinds of clothes by hand. Being a tailor was his only and last job before his death.

    When he was given the world record in 2015, he told reporters about his secret of living a long life, "No smoking or overdrinking! Be happy about everything. Never overdo things. Work and live with happiness.

    Robert Fredy was general manager of a large hotel in Ashbury Park, New Jersey. One cold day two years ago when he stopped his car at a traffic light, Stephen Pearman; an out-of-work taxi and truck driver, walked up to Fredy's car hoping to earn some change by washing his windshield(档风玻璃) , Like many motorists who try to keep the beggars off. Fredy turned on the wipers to show he wasn't interested.

    Pearman put his head close to the window. "Come on, mister. Give me a chance. I need a job, "he said. Something in Stephen Pearman's voice moved Robert Fredy. In the seconds before traffic started moving again, Fredy handed Pearman a business card and told him to call if he was serious.

    "My friends told me he was just pulling my leg," said Pearman. But I said. No, he's a businessman. I need to give it a shot."

    Two days later, 29-year-old Pearman appeared in the manager's office of the big hotel. Fredy gave him a job and lent him packet money while training him.

    Today, Pearman works full-time setting up the hotel's dining halls for business meetings. In the past two years, he has found a flat, married and repaid Fredy's loans (货款).

    "Mr Fredy gave me a second chance." says Pearman. "And I took advantage of it. I could have just come here a while and left. But there is no future washing wind-shields."

    Fredy always keeps away from the street people, "But Pearman seemed so honest and open, asking for a chance rather than just money," Fredy says. "I don't hand my business card to just anybody. But I'm glad I did in this case."
