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
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 ,
是的。conducted to assess the vigilance level of the operator 做定语修饰整个句子的主语the tests，该定语省略which are。
你先找主语、谓语是什么：主语是the tests ，谓语是consist of （由..组成）。主干抓出来了就是：测试分为两个组。然后再看conducted的部分，翻译为：评估操作人员的警觉水平。那这一部分显然是修饰tests的，说明测试的目的是什么。
