摘自《泰坦多元立方》电子书

"A man is not made for defeat A man can be destroyed, is he" - the old man and the sea

Personal attention-seeking means everyone is longing for his ability to get others to his attention, the mentality

Hemingway 1899 was born in America, his life character, brave, strong combative have a strong tendency of personal heroism In Europe, gun battle In the African jungle to catch ferocious beast, in the ring to master the challenge Also in his fiction is full of war, fighting, love sport, and tourism The author of the character of his works is the old man and the sea ", in this work embodies a confident, daring to challenge the fate of courage, show the fighting spirit This work was huge, even as the church sermons

Actually, Hemingway's works in many so-called "heroics" composition, more is the bursting of the emotion, Hemingway other piece like "the sun also rises," "A farewell to arms", "short fiction works", the "garden of Eden", "A Movable Feast" etc, can say "and" personal attention-seeking "almost touch on edge

You can then consider the topic If the old man and the sea ", the following reference analysis

Outstanding performance:

One is to human life Look! The roar of the shark, aggressive resembles, but not a ChuiMu into the old man! Old man with despair, hunger in battle, heart always in silently thoughtfully: people were not born to overthrow It is one of life's tenacity and strong embody!

2 is the ultimate meaning of life works Consider, old man with hunger, cold, dark, don't say to work by a fishbone empty Man is completely cut off line is easy, but he has no! He is in trouble with the strong competition in battle,! YuSiWangPo rather too obstinate Old man and the sea and in the volatile, completed the people's life force Here is the success in said: "life is born, the brilliance of itself, not in a dead results - - - - - - - - the heel in cardiac alive!

Three QuanZhu work is the concept of "success" The win on the material can be secular sense of success, but not necessarily successful life If the life as a business to succeed, then, the life first should be perfect personality Xiang is a loser, but he is recognized as the hero, Liu, but still seized by one as "surabaya rogue" If the solemn, farewell to the significance of human birth

Four works embodies the spirit of America's western values and Adventure and heroics usually for the beauty of the old man, San Diego small fishing boat to upload the mayflower "in" the same spirit, namely: can I failed, but you destroy me, I always strive for a breakthrough Reason: the nationality of works for the works of a worldwide

5 is the work presents a new dialogue between man and nature "The old man and the sea" dialogue ", is weak and strong, loneliness and noise, winning and losing dialogue, it is different from the dialogue with the island, Crusoe is some life Shark, the sea is spoiled, and the spirit of land for long People in turbulent waves, and in living in the region, is absolutely called

6 is the product of work is personified This course should brush, chicheng frankly As is known to all, Hemingway's life in nature, good adventure Challenge vitality He thought, no power of life He hates to human desires, lust, and love, he often bypass the crowd around, magical place hunting, war, piao sentiment Because of this, he mentally alone in the sea as fighting with the old man of sharks However, he was born, until picked a secular evil theory with empty, only to double fishbone tube rifle issued a warning to the world

limitations

This is a novel, but also can take it as a fable Hemingway sing out here to humans fighting spirit stubborn The novel is optimistic note and the end Through the boy will once again with a new man, to fight and a new hope

But, of course, we should also realize that as a bourgeois individual Hemingway's limitations He neither see, see the way society, the strength of the masses, he is in a weak foothold to personal struggle spirit came Consequently, he failed to hero is only the hero The old man and the sea "optimism is wide dark a glimmer of the air, and throughout the is a melancholy throughout the pain

The old man is a real image, or if the employee is but a critics say a laborer appearance of Hemingway's intellectuals We think that is a - the true image of laborer, though, may be slightly The writer is a true to his characters will simply as his mouthpiece If Santiago only cosmetic of Hemingway, this novel won't have such power of moving Santiago's thoughts and feelings and not beyond him such a laborer of thoughts and feelings He in the boundless sea battle with fish, fish that will both as the enemy and as a brother's mood, should be understood and experience In Hemingway's this old man is not a profound social content, but are faithful and true

But the old man Santiago is a writer Ernest Hemingway's shadow His son Gregory Hemingway wrote in a memoir, "Hemingway's hero is Hemingway himself, or his best" This is right We work in some of the many characters are seen writers of his own shadow But, in the novel "the old man and the sea", we felt in the thoughts and feelings with Hemingway, Santiago is more closely together, he loves him, sing praises to him, he entered the ", "the old man in the sea, feeling and sentiment is he to experience In a sense, and from a certain Angle, the old man is Hemingway incarnation But this is not to say ahead of us is a real art image that conflict

In YiJiuErLiuNian, Hemingway published "the sun also rises," in this novel, he expressed in the first world war, the part of the American young intellectuals deep despair of reality He therefore "lost generation" of the identity of the representative by notice, and some people will this novel as a "lost generation" declaration Since then, he has been in his life and society He attended the struggle against Spain franco His works have exposed in the dark, capitalism had antifascist enthusiasm His sympathy for China's Anti-Japanese War He is a serious, right-minded writer But, he always can not out of the circle, and individualism, never get rid of pessimism Although "lost generation" as a literary genre in in the 1930s has collapsed, after the age from thought, said Hemingway is still a "lost" From the surface, Hemingway is a made great achievements, Fraser shatter his reputation, status, money He is bold and unconstrained, open-minded, generous But another Hemingway that he didn't see the real human way And, as in war, it had a few times impaired his health And he is old, writing more and more difficult His heart is depressed, YiYu, doleful In the boundless hugecrowd struggle, ups The old man and the sea "is his soul essence of certain things He not only in the old Santiago's body to his life on the feeling, also be the heroic man to motivate yourself as the example

42

According to his son, Hemingway later in writing up has less easily "The past is a water Wells, and now have the water pump he is no longer poet, he became a workman, blame your destiny, sigh he's going into entangles! � times first-come-first-served basis of dam Lei if ⊙ based Ge He lie � his genius and back, which gives birth to a masterpiece (refers to the old man and the sea"), although not quite, but the scale, insight, and full of love and truth" Anyway, we can agree on the subject, because love, because of the ground with object close together, is the novel can obtain some achievements and can move one of the important reasons -- but generally he is getting on in writing So he had to say such words: "I wrote the book I can't finish line" "I've been in this damned desk before but I can't write out It's not written You know, I can't" His son say: "he always tries to win He was lost, the" He's an old friend Malcolm, says: "if he can't write, he didn't want to live" In 1961, with a rifle bullets ended his life I'm afraid I can't just explain for disease, it should also praised his old Santiago heroism another expression However, we can also be considered that in the boundless huge crowd to struggle, the individual heroes who toil in a bell, their personal power loss after all, just to see more hope
