【难句理解】 Then the person leaves it in a public place, hoping that the book will have an adventure， traveling far and wide with each new reader who finds it. 结构分析：本句是一个复合句。that引导的宾语从句作动词“hoping”的宾语,“traveling…”作宾语从句中的主语“the book”的伴随状语；who引导的定语从句修饰先行词“each new reader”。 汉语大意：接着这个人会把书放在公共场所，希望它能经历一场冒险，跟着能找到它的每位读者四处周游。
