答案

时态有多少种,被动语态就有多少种!因为被动语态的形式是be+动词过去分词,而被动语态的时态是通过be动词体现出来的.如：My car is being repaired now.My car has been repaired.My car was repaired.分别是进行时的被动语态、完成时的被动语态、过去时的被动语态.语态只是说明主语和谓语的关系（主动或被动）,而时态是说明动作发生与时间的关系（过去、现在或将来）.所以问题中的句子一般问成 Whom was the boring book written by 和 Whom has the book been written by .这样才和原句中wrote时态一致.
