　　对他人毫无兴趣，总是独自一人读书的高中生“我”。这样的“我”有一天，偶然捡到一册写着《共病文库》的文库本。那是，天真烂漫的班上人气王·山内樱良私下记录的日记本。里面记载着她身患胰脏的疾病，已经时日无多……。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.这人水下工夫似乎很差，她一击得手，感觉背后水流激荡，本能地一摆双腿避开，侧面又杀来一人。待人走远，秦淼生气地嘟嘴道：既然不相信人家，干嘛要进来？既然进来，也别让师姐给诊脉下方啊。玉儿2岁时家中巨变，被义父吴啸天收养，教授其医术。义父临死前让玉儿不忘家仇。后玉儿为复仇进入药商杜远山府上做丫鬟。当玉儿达到自己目的时，杜远山告知当年的真相，并且给了玉儿盘缠让其离开杜家。后杜府面临困境，玉儿因怀愧疚愿回杜家帮助渡过难关。杜远山之子杜明海早已对玉儿有情，他信玉儿真心帮助杜府，杜府上下却误会玉儿，杜远山却让她再进杜府。玉儿展示非凡医术和管理能力，成为杜府大管家，杜远山临终前将家业托给玉儿，玉儿也找到了失散的哥哥，即杜府大少爷杜明江，可杜明江却被欲望迷蒙了双眼，走上不归路。抗战爆发后，玉儿坚守杜府药厂，在新四军的帮助下，为抗日力量提供药材，为千万抗日战士制造良药。他要把他千刀万剐，不然不足以泄其恨。
