不必了，我还是现在回学校。>尹旭之所以答应，让留下吕伊留在山阴是有缘故的。Liz Bonnin presents a controversial and provocative episode of Horizon, investigating how new scientific research is raising hard questions about zoos - the film explores how and why zoos keep animals, and whether they need to change to keep up with modern science or ultimately be consigned to history.Should zoos cull their animals to manage populations? Liz travels to Copenhagen Zoo, who killed a giraffe and fed it to the lions, to witness their culling process first hand. They think it is a natural part of zoo keeping that is often swept under the carpet. Should some animals never be kept in captivity? In a world exclusive, Liz visits SeaWorld in Florida and asks if captivity drove one of their orcas to kill his trainer.But could zoos be the answer to conserving endangered species? Liz examines their record, from helping breed pandas for the wild to efforts to save the rhinos. She meets one of the last surviving northern white rhinos and discovers the future of this species now lies in a multimillion-dollar programme to engineer them from stem cells. Veteran conservation scientist Dr Sarah Bexell tells Liz the science of captive breeding is giving humanity false hope.感觉不真实，便低头去看小葱。徐夫人就是明白。　　鉴证科探员高达(黄日华饰)利用尸体身上遗下的蛛丝马迹，利用现今各种高科技，为死去的人伸冤，屡破奇案。但，高达却是个怪人，他本为重案组干探，因好赌成性欠下巨债，被迫接受警队内部调查，调职往鉴证科充当文职工作。自六岁那年亲眼目睹死亡开始，他与不可解释之事总是扯上关系。孙婆婆只剩下最后一口气，挣扎着，看向小龙女：求姑娘照料杨过一生一世，别让他吃旁人半点亏。
