    Hans Christian Andersen, a great Danish (丹麦的) writer, is very famous for his fairy tales (童话). He wrote a lot of best-known stories such as The Emperor's New Clothes and The UglyDuckling. His fairy tales have brought happiness to children across the world. The tales have versions (版本) of over a hundred languages.

    Andersen was born in Denmark in 1805. When he was still a young boy, he was already very clever and imaginative (富于想象力的). He created a small toy theatre and made clothes for his puppets (木偶). He also loved reading.

    In 1816, his father died and he learned to be a tailor (裁缝). Later he worked in a factory. At the age of fourteen, Andersen moved to the capital of Denmark to become an actor and gave performances (演出) in the Royal Danish Theatre. However, his voice changed when he grew older, so the job had to stop. Then he began to write poems and fairy tales.

    In the spring of 1872, Andersen fell out of bed and didn't get well again. He lived until 1875 and died peacefully at the home of his close friends.
