同学好！
Three months later Eames appeared for his fourth test - again told to stop - the examiner was thrown forward, 在本句中，again told to stop 是过去分词短语作为后置定语修饰Eames，而在主句中，已经存在谓语动词appeared，所以此处省略了be 动词。本句也可变形为：Three months later Eames appeared for his fourth test ， he was again told to stop...

英语中被动语态中be动词可省略来的常见情况之一：过去分词作后置定语时be 可省略。
如：The boy called Tom is my friend .= The boy who is called Tom is my friend .
那个百名字叫汤姆的男孩是我的朋友。

希望对同学有帮助~
