M:Today we' ll talk about Ernest Hemingway,the famous American writer.Like many great writers,many of Hemingway's books and stories were based on his personal experiences.In 1923,he produced his first collection of short stories,and most of the stories related to his childhood.As we know,in his early twenties,Hemingway lived in Paris and knew many famous writers and artists there.So in his first novel,The Sun Also Rises,he wrote about those gifted but lonely and angry people.In 1929,he produced his fourth novel,A Farewell to Arms,which was based on his experiences during World War II.During World War I,he worked as a reporter in Europe,and he used these experiences to write Across the River and into the Trees.In 1952,he wrote a short novel,The Old Man and the Sea.For this book,he won the Nobel Prize for Literature.Why is it the best?As I said,when he was younger,he used to go fishing with his father and in his later years,deep﹣sea fishing remained his favourite hobby.He was able to write a powerful story because of his own personal experiences.
