There are some topics that readers never grow bored with, and the search for a suitable partner(伴侣) is one of them. Pride and Prejudice(傲慢与偏见)by Jane Austen, first published in 1813, tells the story of five young women, all of whom are looking for a husband. In order to fully understand the novel, the readers must know that at the time when Jane Austen was writing, if a family was not rich, the daughters needed to marry well in order to live a comfortable, independent life. That is the reason why Mrs Bennet, the mother of the five girls, is so eager to have her daughters married.

The heroine of the story is Elizabeth Bennet, and as in all good romantic novels, she and Darcy, the man she finally marries, remain separate until the very end of the story. The wealthy Darcy is a proud, unsociable man, and when Elizabeth hears that he has insulted(侮辱) both her and her family, she dislikes him very much. Poor Darcy then falls head over heels in love with Elizabeth, and has to work terribly hard to persuade her to change her mind about him. He succeeds of course, and they live happily ever after. 

Set at the turn of the 19th century, the novel is still attractive to modern readers. It has become one of the most popular novels and receives great attention from literary scholars(学者).Modern interest in the book has resulted in a number of dramas(戏剧)and a lot of novels and stories modeling(模仿) after Austen’s memorable (难忘的)characters or themes. To date, the book has sold some 20 million copies worldwide.

Jane Austen is rightly famous for her style. Her sentences have a wonderful rhythm(韵律), and she makes such clever, true comments about people. It is not surprising that Pride and Prejudice has lasted.
