More than 200 sightings of great white sharks are recorded every year in False Bay, near Cape Town, South Africa. But in 2019, that number was zero.rnIt\'s two years now since they vanished, and the economic impact has been devastating. The great white shark tourism industry has collapsed.rnBut why did they disappear? It\'s possible that orcas are the culprits—they\'re known to attack great whites, and have a particular taste for their livers. Indeed, sightings of great whites decreased after two orcas visited False Bay in 2015.

明清时期,汉语在暹罗的传播主要有官方和民间两种途径。官方层面的传播围绕着朝贡贸易活动开展,交流需求促使暹罗官员到中国国子监学习汉语,朝贡物品出现汉文书籍、砚台,来华朝贡的暹罗使臣主动学习汉文诗词,具有传播方式单一、传播范围狭窄、传播内容固定的特点;民间层面的传播在多次华人移民潮影响下,出现汉文小说的口头与书面流传、家庭华文教育等多种传播途径,该层面传播方式具有自发性、灵活性和长久性的特点。总体来说,汉语在暹罗的传播情况并不理想,原因一是古代泰国与中国交往较少,却深受印度文明影响,以印度文字为基础创制本国文
