【分析】本题考查定语从句的应用，需掌握关系代词that、which、who的用法规则：1. 先行词指物时，关系代词可用that或which；2. 先行词指人时，关系代词可用that或who；3. 当先行词被形容词最高级、the only等修饰时，关系代词只能用that；4. 合并句子时，需确定先行词，将后句变为定语从句修饰先行词，关系代词在从句中作宾语时可省略（本题填空处为关系代词，需根据规则选择）。
【解析】

③先行词为anyone（人），关系代词在从句中作knows的主语，可用that或who；
④先行词为person（人），且被the only修饰，故用that；
⑤先行词为book（物），关系代词在从句中作talking about的宾语，可用that或which；
(2) 句型转换：
①先行词为schoolbag（物），关系代词用that/which；从句谓语为lost，故填that / which; lost；
