【正确答案】 D

【答案解析】[听力原文]
   There is something about water that makes it a good metaphor for life. That may be one reason why so many people find relief in swimming when life's seas get rough. And it goes some way towards explaining why books about swimming, in which people tackle icy lakes, race in rivers, and overcome oceans while reflecting on their lives, have recently become so popular.
   These books reflect a trend, particularly strong in Britain, where swimming in pools is declining, but more and more folks are opting for open water. "Wild swimming" seems to be especially popular among women. Jenny Landreth recently published a guide to the best swimming spots in London. Her new book, Swell, interweaves her own story with a history of female pioneers, who accomplished remarkable feats and paved the way for future generations.
   Notions of modesty restricted women in the Victorian era, but they still swam. A "bathing machine" was rolled down to the seashore so women would not be seen in swimwear. In 1892 The Gentle woman's Book of Sport described a woman swimming in a heavy, dress, boots, hat, gloves and carrying an umbrella.
   Eventually, swimming became freer. Mixed bathing was permitted on British beaches in 1901. Women won the right to swim in public pools, learned to swim properly, created appropriate swimwear and, in time, even competed against men. The first woman to cross the English Channel was Gertrude Ederle in 1926. She beat the record by almost two hours and her father rewarded her with a red sports car.
   What has become so popular recently?
录音在开头提到，关于游泳的书最近盛行起来(books about swimming... have recently become so popular)，D项中的Books about swimming为原词复现，故选D项。
   A项“水上运动”在录音中没有提到。B项是利用race in rivers设置干扰，录音说的是教授如何进行这项竞技的书受欢迎，而不是这项运动受欢迎，故排除B项。C项是利用文中个别字词拼凑而成，故排除。
