when the fireman arrived on the scene,it was possible to identify oly about bodies,with the others__to ashes.
reduced had been reduced why?
reduced had been reduced why?
reduced, 因为 had been reduced 形容一个人，而others 是很多人。
burned
had been reduced
已经完成的动作应该用完成时态
had是过去式，可以形容一人或者多人
应该是reduced, 整句话的谓语部分是,be possible to.....,而had been reduced 中也有谓语动词 have been , 最起码一句话中不可能有两个动词吧
