This book tells a story of a dog called Buck transformed from mildness in civilized world to wildness world widely existed in the harsh reality. Nevertheless,what attracts me most in The call of the wild is not the description of Buck but lies in its reflecting society survival rules and its promoting（弘揚(yáng)）noble quality such as loyality,persistence，struggle and so on through this story.
The principle of survival
――Obedience（服從）
Buck had been suddenly jerked（急拉次洼，猛拉）from the heart of civilization and flung into（被拋進(jìn)）the heart of things primordial（原始的谬晕，根本的）.Before he realized the cruel reality,he was destructively（狼狽地）beaten by a man with a club（棍子）.Having learned the lesson,he cottoned on to（醒悟叮雳，明白）the fact that a man with a club was a lawgiver（立法者）,a master to be obeyed,though not necessarily conciliated（馴服鹰祸，安撫）and in all his afterlife he never forgot it.Obedience doesn't mean weakness and inaction（無為）but flexible performance according to situation.
――Defeat others
Spitz and he were rivals（對手）who had been fighting for the leader.But Spitz,cold（冷靜的）and calculating（精明的）even in his supreme（最高的赤拒，最重要的）moods,prevail（占上風(fēng)）initially in combat.He must master or be mastered.Eventually,he defeated Spitz for saving himself.By conquering more and more dogs,he was stronger and stronger so that he had become insensible to the bite（刺痛榔至，咬）of the lash（鞭子，責(zé)罵）or the bruise（擦傷闹瞧，瘀傷）of the club.
Loyality and ideologism（執(zhí)著）to love
Different from other masters who treated him as a labour and never heartily cared about him,John took care of him heartily and sincerely and thought him like his kids.So he really fell in love with John and never let John out of his sight.For saving John,he didn't grudge（吝惜）his life to protect John.Besides,heart-broken and furious（暴怒的）,he tore（撕裂）their throats who killed his loved master to revenge（報(bào)仇）for John.Most incredibly（難以置信的）, he would return to mourn（哀悼）John.So deeply moved am I ,I want to ask :Can a real man be so loyal and persistant to do like this绑雄？
The pursuit of nature
Ostensibly（表面上）he was compelled（迫使，強(qiáng)迫）to be wild by cruel reality,but in fact,it was his nature of wildness that called him and ultimately led him to return to nature step by step.Simultaneously（同樣地）,our human beings should also recognize ourselves and pursue our inner nature.
