Abstract: I read The Call of the Wild during May Day, a novel by Jack London who was an American author. Buck, a domesticated dog living at a ranch in the Santa Clara valley of California is the novels central character. Unfortunately, he is stolen by the gardener and sold into the brutal existence of an Alaskan sled dog. He reverts to atavistic traits. Buck has to adjust to, and survive, cruel treatments and fight to dominate other dogs in a harsh climate. He sheds the veneer of civilization, relying on primordial instincts and lessons he learns, to emerge as a leader in the wild at last. While reading the story of Buck, I shed tears of sorrow and sympathy, and was moved by great courage and the bravery he has shown in the face of every challenge. The only thing I can do is to cheer for him in silence and wish he can be stronger to fight with difficulties. From Buck, what I have learnt is to fight bravely and intellectually until the last minute in my life. And that is a great asset we should learn to gain. I choose the book to finish my book report just because I appreciate Buck very much. Key words: brave, perseverance, The Call of the Wild, survival, fightingFirst of all, I would like to mention the author Jack London when I share my views of The Call of the Wild. London was a passionate advocate of unionization, socialism, and the rights of workers and wrote several powerful works dealing with these topics such as his dystopian novel The Iron Heel, his non-fiction expos The People of the Abyss, and The War of the Classes. 1From his works, we can easily see that Jack London writes books in a way of realism and naturalism. Also the reflection of naturalism is manifested in The Call of the Wild. With The Call of the Wild published in 1903, it made a reputation for London. As early as 1908 the novels was adapted to film and it has since seen several more cinematic adaptations. The book secured London a place in the canon of America literature. The Call of the Wild is one of the masterpieces of Jack London, which was combined with his experiences in the north when he was engaged in looking for gold. 3 The story was written as a frontier adventure and in such a way that it worked well as a serial., it is good episodic writing that embodies the style of magazine adventure writing popular in that period. It leaves us with satisfaction at its outcome, a story well and truly told, As Doctorow points out he said.As we can know (if you have read the book), Buck has a lot of excellent quality, such as loyalty, powerful, intelligence and valiant fighting. At the same time, Buck is thankful. He will return for someone who is good to him. Just like John Thornton, a man had saved his life and became his ideal master, Buck saves the guys live and protect him in all time. “For a long time after his rescue, Buck did not like Thornton to get out of his sight.”, ”At such times he would shake off sleep and creep through the chill to the flap of the tent, where he would stand and listen to the sound of his masters breathing.”4 You have to admit that you also feel warmly when you across these sentence. Here, I feel Bucks endless love for his master. When John Thornton was killed, for the first time in his life he allowed passion to usurp cunning and reason, and it was because of his great love for John Thornton that he lost his head. I do not think Buck will go back forest if John Thornton did not lose his live. Perhaps this is one aspect that Buck does better than most people. As far as I am concerned, you can lose everything, but a thankful heart. Heart of appreciation is of great significance in our lives. A grateful heart is full, it is happy!After a long honed metaphor, in the face of harsh persecution or against without weakness and fearless, Buck became stronger. Bucks response to the call of the wild was actually the continued the process of mining process of their own potential. To survive, he fights with the cold weather; to survive, he fights with other dogs; to survive, he fights with human. With the fierce struggle and the ability to quickly adapt to the environment, he turns to be the strong. You would admire that Buck is excellent to pursuit life himself. However difficult, he pulls through in the end. He is the last winner.There is something we can learn from Bucks world. The law of club is one of them. When Buck was forced to sell the new owner, he tried to fight in his own way to show his unwilling. However, the law of club forced him to surrender the principles of the master. Of course it is wise of him to do so. It makes readers feel he is not a dog, because it owns the quality and characteristics we human have. No one would be so stupid that he still try it on the occasions of weak. Even in the true world of human, many people will choose to show themselves forbearing and conciliatory for the sake of the common good. They would not parade their superiority and strive to outshi
