The nature of active-sites and the mechanism of promotion are discussed according to the results.展开更多

It mainly described an unmarried woman without a wedding ring in a public buildings in a certain town died after giving birth to an orphan. The author through the orphan Oliver Twist's sufferings, described a child not changed his good nature no matter how bad the environment was, not dyed by the surrounding environment, finally adopted by a gentleman to live a happy life. At the same time, the works also described some ugly social phenomenon, as represented by the Jews Fagin and Bill Sikes used children to steal, and guided them for error education, made the children went to a circuit. The author depicted some distinctive characters, but also had its limitations. The author was too idealistic in depicting the bourgeois virtues, but in depicting the social crime phenomenon reflected his prejudice against the Jews.展开更多
