時(shí)態(tài)有多少種,被動(dòng)語(yǔ)態(tài)就有多少種!因?yàn)楸粍?dòng)語(yǔ)態(tài)的形式是be+動(dòng)詞過(guò)去分詞,而被動(dòng)語(yǔ)態(tài)的時(shí)態(tài)是通過(guò)be動(dòng)詞體現(xiàn)出來(lái)的.如：My car is being repaired now.My car has been repaired.My car was repaired.分別是進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)、完成時(shí)的被動(dòng)語(yǔ)態(tài)、過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài).語(yǔ)態(tài)只是說(shuō)明主語(yǔ)和謂語(yǔ)的關(guān)系（主動(dòng)或被動(dòng)）,而時(shí)態(tài)是說(shuō)明動(dòng)作發(fā)生與時(shí)間的關(guān)系（過(guò)去、現(xiàn)在或?qū)?lái)）.所以問(wèn)題中的句子一般問(wèn)成 Whom was the boring book written by 和 Whom has the book been written by .這樣才和原句中wrote時(shí)態(tài)一致.
