Mark Zuckerberg, the founder of Facebook, is an American computer programmer. His net worth (资产净值) is about $71 billion, ranking him the fifth richest person in the world. On 1 December, 2015, he and his wife announced that they would give 99 per cent of their Facebook shares to the Chan Zuckerberg Fund. Since 2010, Time magazine has named Zuckerberg among the 100 wealthiest and most influential people in the world.

    Born in 1984, he and his three sisters were brought up in a small village in New York. At high school, Zuckerberg was outstanding in class. He won prizes in science. He could also read and write French, Hebrew, Latin, and ancient Greek. Zuckerberg began using computers and writing software at middle school. His father taught him basic programming in 1990. He enjoyed developing computer programs, especially communication tools and games. During his high school years, he built a software program called ZuckNet that allowed all the computers between the house and his fathers dental office to communicate with each other. The following year, he built a music player called the Synapse Media Player. It used machine learning to learn the user's listening habit.

    In 2004, Zuckerberg launched Facebook from Harvard. He left Harvard in his second year to complete his project—Facebook. Helped by his college roommates and fellow Harvard students, Facebook expanded rapidly, reaching one billion users by 2012.

    In 2003, Zuckerberg met Priscilla Chan, at a party during his second year at Harvard. They have been dating since their Harvard days. In 2010, they got married and had their first baby, Maxima. The couple announced on their Chinese New Year video that their daughter's Chinese name is Chen Mingyu. On 18 March, 2016, while visiting Beijing, he posted on Facebook, "It's great to be back in Beijing! I kicked off (开始) my visit with a run through Tiananmen Square, past the Forbidden City and over to the Temple of Heaven." With a Chinese American wife and speech in Mandarin (普通话) in Tsinghua University, Zuckerberg is famous in China. He seems to be willing to take efforts to make Facebook available in the mainland to connect all people in the world.

    This year the US will honour(纪念)one of the country's most famous writers-Mark Twain(1835-1910).Most readers know that his real name was Samuel Langhorne Clemens, but how many know where the pen name "Mark Twain" came from?

    The answer shows Clemens' colourful early life before he became a writer. "Mark Twain" was the cry shouted on a ship when the ship entered a part of a river that was two fathoms(6 feet) deep. "Twain" is an old-fashioned way of saying "two". Twain trained as a ship pilot on the Mississippi river for two years, a time that he wrote about in the humorous Life on the Mississippi(1883).

    The famous river would become an important theme in many of his works-who could forget the journey of Huck and Jim along it in his most famous book, The Adventures of Huckleberry Finn(1884).

    With little education, he had to teach himself how to write stories. Whenever possible, he would go to public libraries. There he spent much time reading and thinking, which greatly helped him with his writing.

    On the other hand, his life experiences gave him wonderful material to write about and attract readers. Twain wrote in a style that has been called "local colour" because it shows great knowledge of local people and their customs.

    The gift is very clear in the two books for which Twain is still celebrated today: The Adventures of Tom Sawyer(1876) and its follow-up The Adventures of Huckleberry Finn, which many people call "The Great American Novel".

    The most amazing invention in his book is the voice of Huck himself. Huck did not enjoy schooling. It shows in the way he uses language, in a spoken style. Only a master like Twain could copy the way a young southern boy talked so well.
