　　一段名为《和豚说话的女孩》(The Girl Who Talked to Dolphins)的纪录片将于6月17日在英国广播公司（BBC）播出。
　　美国研究员霍韦（Margaret Howe）于上世纪60年代参与一项动物实验，尝试教导6岁大的樽鼻海豚彼得（Peter）说英语，希望证实海豚具有如人类般的语言能力。虽然彼得的学习成果有限，却意外爱上了与它朝夕相处的霍韦，编织出一段凄迷的“人豚恋”。
　　来自美属维尔京群岛的霍韦，在下周播出的英国广播公司（BBC）纪录片讲述这段经历。当年仅23岁的霍韦，于1965年参与着名神经学家利利主持的实验，被安排入住“海豚之家”10周负责教彼得英文，无论用餐、洗澡、睡觉或玩耍都在一起。
　　彼得仅学会“ball”（球）及“diamond”（钻石）等单字，却对霍韦日久生情。它被霍韦冷落时会“呷醋”，甚至对她展示性欲，多番将自己挤向她的双腿之间，并绕着她不断转圈。霍韦只好安排彼得与另外两条海豚生活来抑制它。
　　彼得可能感到自己过于热情吓坏了霍韦，变得较为温和；渐渐霍韦亦对它产生情愫。可惜实验后来因经费不足告吹，彼得被移送至迈阿密。与“爱人”分离的彼得或因心碎，数周后闭气沉于池底自杀身亡。
