Albus 人名,称呼语do you really think 主句,“你真的认为?”it's safe leaving him with this people 宾语从句,在宾语从句内部又如下分析：it 形式主语leaving him with this people 这是-ing形式做真正的主语this ...leaving him with this people不是状语吗？-ing 在句子中可以充当主语，宾语，表语，宾补，定语，状语。在这句中，我认为 -ing 短语作真正的主语，it 作形式主语。如果你认为 leaving him with this people 作状语，那么 it 指代什么？我还是坚持上述观点。
