【正确答案】正确答案：In the nineteenth century, many progressive writers wrote excellent works to unveil the dark society. Charles Dickens(1812 ~ 1870)and Mark Twain(1835 ~ 1910)were the most outstanding representatives of them. Oliver Twist is the masterpiece of Charles Dickens and Mark Twain" s masterpiece is The Adventures of Huckleberry Finn. The two books share the theme of a corrupt adult society, and the irony in both works is often centered on racism and religion. Both novels are adventures of children. Oliver Twist is based on real life materials such as the New Poor Law of 1834 and the current trial of a notorious fence and thief-trainer. By following the most unfortunate experience of a poor orphan boy, Oliver, the author means to give a vivid picture of the underworld with all kinds of thieves, prostitutes and murderers as well as the horrible cruelty of the workhouse system of the time. Oliver is the first of that brilliant group of child characters who are the very images of innocence, love and honesty. The novel leads to a happy ending. Dickens lives and writes in the Victorian age when English society began to feel the impact of change but still managed to keep the old values intact. Industrialization and capitalism had begun to bring wretchedness into the country, but life had not become totally impossible. So, English realist writers like Dickens were basically optimistic. They were aware of modern ills which they lost no time to castigate, but still wrote with the notion that the world was basically good and could become better. The adventures of Huckleberry Finn tells a story about the United States before the Civil War, around 1850, when the great Mississippi Valley was still being settled. Here lies an America, with its great national faults, full of violence and even cruelty, yet still retaining the virtues of "some simplicity, some innocence, some peace. " Here is a "hymn" to that ante bellum America, the moral values of which vanished with the war. The machine and the worship of money were on their way in, but the river-god, with its " sunlight, space, uncrowded time, stillness, and danger," has not been forgotten. Similar to English realists, American realist novelists took the side of the defenseless or oppressed, and fought corruption, privilege and abuse of the society , but the Civil War and the American Dream played important roles in their writing.
