Question

--Jim, did you take out the trash just now?
--No. By the time I came home it          .
A. have been taken out      B. had taken out          C. had been taken out

Answer 1

C

試題分析：take out拿出，帶出，by the time直到，came home是過(guò)去時(shí)，扔垃圾是發(fā)生在came之前的動(dòng)作，過(guò)去完成時(shí)表示的是過(guò)去的過(guò)去。又有be+動(dòng)詞過(guò)去分詞構(gòu)成被動(dòng)語(yǔ)態(tài)。had been+過(guò)去分詞，含有被動(dòng)語(yǔ)態(tài)的過(guò)去完成時(shí)。句意：Jim，剛才是你把垃圾扔了嗎？不，我回來(lái)的時(shí)候垃圾已經(jīng)被扔了。故選C。
