　　雅思基础阅读难句解析-插入结构

　　3.Still, he could not help thinking that if anything should happen, the nearest person he could contact by radio, , would be on an island 885 miles away.

　　结构：共有5个谓语动词：could not help/should happen/could contact/was/would be，主句谓语动词为could not help。that引导think的宾语从句。could contact属于定于从句，省略了引导词，修饰person。unless引导条件状语从句，为插入语。拆分为：

　　1) Still, he could not help thinking.

　　2) That if anything should happen.

　　3) The nearest person would be on away.

　　4) he could contact the person.

　　5) Unless there was a ship nearby.

　　翻译：他仍然忍不住想到，如果发生了什么意外，那么除非附近有条船，否则它能用电台联系到的最近的人也885英里之外的岛屿上。
