There are many famous writers in the English world, among whom Jane Austen  (1775—1817) has been popular with all ages. But then Jane Austen wrote her novels in England, she was writing about a world that most of us would not recognize.

But today Austen’s books are in greater demand than ever. In the last ten years, five of the six novels have been made into Hollywood films, while her books continue to be bestsellers. So why is Austen still popular?

Richard Jenkyns, a professor of English at Oxford University, argues that her novels still appeal to people because they focus on issues that are as relevant today as they were when she wrote them. Her novels are about women trying to find a perfect husband, but also explore issues surrounding marriage, friendship and the family. “The plots are fairly timeless stories about human interaction which are familiar to us,” Jenkyns says.

The most famous book Austen wrote is Pride and Prejudice, a love story between Elizabeth Bennett and Mr. Darcy. At first the two characters do not get on. They finally fall in love, but still have to overcome opposition (反对) to their relationship from their families.

All of Austen’s books are easy to read, making them popular with children and adults, but they work on different levels so people can take what they need from them, author Kate Henry says.

Austen is often praised as the greatest romance writer in the English language, so it is surprising she remained unmarried. “Maybe she was too much of a romantic, waiting for a perfect man,” Henry says.

下面各句中翻译不恰当的一项是:(  )

A.屈原既放,游于江潭,行吟泽畔,颜色憔悴,形容枯槁。

屈原被放逐之后,在江湖间游荡。他沿着水边边走边唱,脸色憔悴,形体容貌枯瘦。

B.圣人不凝滞于物,而能与世推移。世人皆浊,何不淈其泥而扬其波?众人皆醉,何不餔其糟而歠其酾?何故深思高举,自令放为?

通达事理的人不拘泥于外物,而能随着世道变化推移。既然世上的人都污浊,您为什么不使那泥水弄得更浑浊而推波助澜?既然众人都沉醉不醒,您为什么不也跟着吃那酒糟喝那酒汁?为什么您偏要行为高出世俗,使自己被放逐呢?

C.吾闻之,新沐者必弹冠,新浴者必振衣;安能以身之察察,受物之汶汶者乎!宁赴湘流,葬于江鱼之腹中。安能以皓皓之白,而蒙世俗之尘埃乎!

我听过这种说法:刚洗头的人一定要弹去帽子上的尘土,刚洗澡的人一定要抖净衣服上的泥灰。怎么能用洁白的身体去接触外物的玷污?我宁愿投身湘水,葬身在江鱼的肚子里,怎么能够用清白的人格,去蒙受人世间的尘土呢?

D.怒而飞,其翼若垂(边陲)天之云。一发怒就飞,它的翅膀就像天边的云。
