请问大神这句英语结构分析was the only person among 200 researchers Jack contacted who showed interested in his project
网友回答
He was the only person among 200 researchers Jack contacted who showed interested in his project.
分析：主句：He was the only person
状语：among 200 researchers
定语从句1：Jack contacted （因为先行词在定语从句中做宾语,所以省略了引导词whoi,修饰person）
定语从句2：who showed interested in his project.（也修饰person）
