— I’m sorry to tell you that you made a mistake in your test.— How can that be? I did it

问题补充：

— I’m sorry to tell you that you made a mistake in your test.

— How can that be? I did it in class.

A. as told

B. as am told

C. as telling

D. as I told

答案：

(答案→)A. as told

B. as am told

C. as telling

D. as I told

解析：句意：--很抱歉告诉你你在考试中犯了一个错。--怎么会？我是按照在班级老师教我的那样做的。这里as引导的是方式状语从句，完整的是：I did it as I was told in class.当主从句省略的时候，可以省略从句的主语和be动词，所以选A。
