Question

—Who should be responsible for the accident?
—The boss, not the workers.They just carried out the order       .

A．as told

B．as are told

C．as telling

D．as they told

Answer 1

A

as told="as" they were told, 此处是as引导的方式状语从句的省略。当从句主语与主句主语一致, 且谓语动词含有be时, 将从句的主语和be省略。又因为workers与tell之间是被动关系, 排除C、D。
