（单词翻译）

 Isaac Asimov was an American scientist and writer who wrote around 480 books that included mystery stories, science and history books, and even books about the Holy Bible and Shakespeare. But he is best known for his science fiction stories. Asimov had both an extraordinary imagination that gave him the ability to explore future worlds and an amazing mind with which he searched for explanations of everything, in the present and the past.
       Asimov's life began in Russia, where he was born on 2 January, 1920. It ended in New York on 6 April, 1992, when he died as a result of an HIV infection that he had got from a blood transfusion¹ nine years earlier.
       When Asimov was three, he moved with his parents and his one-year-old sister to New York City. There his parents bought a candy store which they ran for the next 40 or so years. At the age of nine, when his mother was pregnant² with her third child, Asimov started working part-time in the store. He helped out through his school and university years until 1942, a year after he had gained a master's degree in chemistry. In 1942 he joined the staff of the Philadelphia Navy Yard as a junior chemist and worked there for three years. In 1948 he got his PhD in chemistry. The next year he became a biochemistry teacher at Boston University School of Medicine. In 1958 he gave up teaching to become a full-time³ writer.
        It was when Asimov was eleven years old that his talent for writing became obvious. He had told a friend two chapters of a story he had written. The friend thought he was retelling a story from a book. This really surprised Asimov and from that moment, he started to take himself seriously as a writer. Asimov began having stories published in science fiction magazines in 1939. In 1950 he published his first novel and in 1953 his first science book.
       Throughout his life, Asimov received many awards, both for his science fiction books and his science books. Among his most famous works of science fiction, one for which he won an award was the Foundation trilogy (1951-1953), three novels about the death and rebirth of a great empire in a galaxy⁴ of the future. It was loosely based on the fall of the Roman Empire but was about the future. These books are famous because Asimov invented a theoretical framework which was designed to show how ideas and thinking may develop in the future. He is also well known for his collection of short stories, I, Robot (1950), in which he developed a set of three "laws" for robots. For example, the first law states that a robot must not injure human beings or allow them to be injured. Some of his ideas about robots later influenced other writers and even scientists researching into artificial intelligence.
        Asimov was married twice. He married his first wife in 1942 and had a son and a daughter. Their marriage lasted 31 years. Soon after his divorce in 1973, Asimov married again but he had no children with his second wife.
