英语语法问题,定语从句的问题
语法疑问:The tests conducted to assess the vigilance level of the operator consist of two groups:performance based or measuring ocular physiology.这句话前面的The tests conducted to是什么用法呢?是定语从句省略了关系代词和are吗?等待英语语法大神~
conducted to assess the vigilance level of the operator 是过去分词短语作后置定语修饰前面名词tests也可改为定语从句即 The tests which/are conducted to assess ,
