Mark Twain tells a boy’s story in The Adventure of Huckleberry Finn. Huck is a poor child, without a mother or home. His father drinks too much alcohol and always beats him.

Huck’s situation has freed him from the restriction of society. He explores in the woods and goes fishing. He stays out all night and does not go to school. He smokes.

Huck runs away from home. He meets Jim, a black man who has escaped from slavery(奴隶制). They travel together on a raft(木筏) made of wood down the Mississippi River.

Mark twain started writing “Huckleberry Finn” as a children’s story. But it soon became serious. The story tells about the social evil of slavery, seen through the eyes of an innocent child. Huck’s ideas about people were formed by the white society in which he lived. So, at first, he does not question slavery.Huck knows that important people believe slavery is natural, the law of God. So, he thinks it is his duty to tell Jim’s owners where to find him.

Later, Huck comes to understand that Jim is a good man. He finds he cannot carry out his plan to inform Jim’s owners of his whereabouts(下落). Instead, he decides to help Jim escape. He decides to do this, even if God punished him.
