摘  要

狄更斯是十九世纪批判现实主义的奠基者，《雾都孤儿》是他的成功之作之一。小说描写了伦敦底层社会中贫苦儿童的悲惨生活,揭露了贫民救济所的黑暗。他所塑造的人物,在今天读来仍栩栩如生。狄更斯通过对小说中不同人物的形象描写突出了纯洁和善良的品质，深刻反映了当时社会的黑暗和腐败，及对不服并反抗现状的精神的讴歌。只有善良才能战胜黑暗势力，才能冲破一切阻碍，获得安心。奥利弗，南希，费金，他们每个人都具双重性格，但是作者想表达的纯洁最终战胜邪恶的真理是不变的。奥利弗在各种各样的人的帮助和陷害下，心中有一份信念，始终保持一颗善良、纯洁、天真的心，生活在伦敦当时如此腐败而混乱的社会中，最后在罗斯和南希的帮助下，过上了幸福的生活。我们要始终像主人公那样，保持纯洁善良，懂得其意义，在现代生活中获得精彩。

1  Background Information
1.1 The background of the society
    At the beginning of 19 century, England was undergoing a revolution from agriculture to an industry country. The economy had developed rapidly, with the rich becoming richer and the poor suffering a lot became poorer. The condition of poverty was the most important weakness in that society, and some poor people even chose to die rather than being in such a suffer. Life promoted but the transformation seemed harmful. Dickens wrote many works according the experience with the society; the transformation and development provided rich material for Dickens’ writing. And the writers at that time had sympathy for the miseries and a strong feeling for the poor. They did not approve of violence to fight the social evil, which actually is the truth. Only peace can make life normal and beautiful, instead of violence and war.
