The remarkable American writer Jack London (1876-1916) lived a difficult life. During his school years, he sold morning and evening newspapers, worked part-time at a bowling alley on weekends, entered a cannery at the age of 14, then illegally caught oysters in San Francisco Bay, and then hired himself as a sailor on a fishing schooner. Jack London's essay "tYphoon off the coast of Japan", for which he received the first prize of one of the San Francisco newspapers, was published in 1893 and served as the beginning of his literary career. Jack London began to study literature more seriously at the age of 23, after returning from Alaska. He devoted all his energy to writing books and wrote almost the whole day, leaving only a few hours to rest and sleep.The novels 'Jerry the Islander' and 'Michael, Jerry's Brother', which Jack London himself was particularly fond of, were published after the author's death. "Michael, Jerry's brother" continues the story of two intrepid, noble and full of love for life terriers, whose names have become a symbol of friendship and loyalty.For middle school age.
