—Who should be responsible for the accident?

—The boss, not the workers. They just carry the orders.

A. as told

B. as are told

C. as telling

D. as they told

答案：

(答案→)A. as told

B. as are told

C. as telling

D. as they told

解析：句意：--谁应当对这起事故负责任？--老板，不是工人，他们只是执行命令罢了。as引导的是方式状语从句，它是省略句，完整的是as they were told，这里把主语及be 都省去，故选A。
