　　Poet Simon Armitage traces the evolution of the Arthurian legend through the literature of the medieval age and reveals that King Arthur is not the great national hero he is usually considered to be. He's a fickle and transitory character who was appropriated by the Normans to justify their conquest, he was cuckolded when French writers began adapting the story and it took Thomas Malory's masterpiece of English literature, Le Mort d'Arthur, to restore dignity and reclaim him as the national hero we know today.

　　A look at the relationship between big cats in the wild and our domestic pussycats, and the feline species' journey from hunters of the wild to household pets.

　　After four decades of reporting from the continent, Jonathan Dimbleby returns to Africa on a 7,000-mile journey to discover how it is changing.
　　【Mali, Ghana and Nigeria】
　　He starts his African journey in the capital of Mali, Bamako, the fastest-growing African city. Following the course of the Niger river, Dimbleby finds not a continent of beggars but of industrious people, some of whom go to extraordinary lengths to make a living, free-diving 20 feet to excavate building sand.
　　Travelling north-east, he sees how tradition is preserved in an area where a sophisticated urban society has thrived for 1600 years. Jonathan gets his hands dirty as the apprentice of a 74-year-old mud mason in Djenne, a town built entirely of mud.
　　In Ghana, one of Africa's freest and most stable countries, Jonathan sees a spectacular festival before playing a game of golf with the King of the Ashanti, who recalls his time working for Brent council. Dimbleby attends the King's court to see what lessons the UK can draw from traditional African structures that promote harmony and reconciliation.
　　Jonathan discovers that the African brain drain is turning into a brain gain as economic opportunity and patriotism draw people home. Football unites Ghana like nothing else, superseding political and tribal divisions. There is a rich seam of young football talent on the continent in the year that the World Cup is hosted by an African nation for the first time.
　　In Lagos, Nigeria's business capital, Jonathan Dimbleby sees a different take on a city that is often depicted as a hotbed of violence, crime and corruption. He is taken on a private jet by Africa's richest man, then savours the creative talents of two of African music's rising stars who are helping to cement Lagos's place as the continent's cultural hub.
　　【Ethiopia, Kenya and Tanzania】
　　On the second leg of his illuminating journey across Africa, Jonathan Dimbleby travels 2000 miles through East Africa's Rift Valley.
　　Starting in Ethiopia, where he was the first journalist to report the 1973 famine, Dimbleby discovers the great strides being made to safeguard the country from future catastrophes.
　　In Kenya he finds out how mobile phones are revolutionising small businesses and even the lives of Masai tribes.
　　In Tanzania he joins in a football match with the judges and guards of Africa's own Human Rights Commission and meets the street kids in Dar-es-Salaam who are building an international profile for their music.
　　【Congo, South Africa and Zambia】
　　On the final leg of his 7,000-mile odyssey, Jonathan Dimbleby travels from Congo to Durban in search of the stories revealing contemporary Africa.
　　He learns how China's billion-dollar deals have rebooted African economies, once dependent on Western aid and investment.
　　Passing through Zambia, Jonathan survives a training session with boxing world champion Esther Phiri and meets Hugh Masekela, who shares with him his view of Africa's emerging revival.

　　这部名为《北极熊：冰上侦探(Polar Bear: Spy On The Ice)》的纪录片将于29日在英国BBC1电视台播放。
　　北京时间12月28日消息，野生动物纪录片拍摄人员往往需要绞尽脑汁，不断增加拍摄方法的隐秘性，才能悄悄潜入到他们想要拍摄的动物世界里，窥探它们的一举一动，但是不要认为这些动物都很愚笨，下面的图片就是很好的证明。
　　获奖导演约翰·唐纳最近把他的遥控间谍相机装扮成一个大雪球，用来追踪一只北极熊母亲带着它的小幼仔穿过挪威斯瓦尔巴特群岛的海冰，寻找海豹的过程。但没想到的是，这种伪装并没能骗过附近的一只成年雄性北极熊的眼睛。它快速追上移动照相机，用大而有力的爪子对眼前的“雪球”进行一番摸索，让唐纳和他的制片人拍了一些特写后，很快把相机砸得粉碎。
　　但它并没就此罢休，它想都没想，又开始追赶唐纳的另一个价值10万英镑(15.45万美元)的暴风雪相机。这个相机上带有轮子，可以遥控操作，尽管吃了一惊的纪录片拍摄者设法遥控这个昂贵的设备逃跑，但是被激怒的北极熊一直穷追不舍，最后这只体重超过半吨的北极熊把第二个相机也砸得粉碎。
　　不过幸运的是，唐纳还有另一个相机，它记录了摄影设备遭袭的整个过程。北极熊毁掉两个相机后，慢慢变得平静下来。唐纳说：“好奇心得到满足后，这些动物开始表现正常起来。最终我们的间谍相机显示，北极熊的‘智慧和好奇心’是它们在海冰不断缩小的情况下继续幸存下来的关键。”
