the finding comes from a survey of nearly 30000 American adults conducted between 1975 and 2006 请问conducted 之前有没有省略。 如果省略是省略什么？能否举个例子。谢谢
是省略that was 。什么时候可以省略？ 整句话怎么翻译?

这是名动词修饰adults，可以说adults that are conducted（定语从句）
如果是动词的ing形势，表示与被修饰词是主动关系，比如The man coming from American looks nice中coming 修饰man，由于man 和come是主动关系，所以用coming
如果动词使ed形式，表示与被修饰词是被动关系，比如本例，再比如The book written in 1996 is still available at many bookstores.
