问题补充:
It is said that the old pot under the earth for about 1000 years by the time it was discovered.
A. had buried
B. had been buried
C. buried
D. were buried
答案:
A. had buried
(答案→)B. had been buried
C. buried
D. were buried
解析:考查时态与语态。By要与完成时连用,本题by后面跟的是过去的时间,要与过去完成时连用,意义是又是应该被动,所以选B。句意:据说那个旧罐在被发现之前已经在地下被埋了1000多年了。
