(A)  Some buildings that were destroyed and heavily damaged in the earthquake last year were
(B)  Some buildings that were destroyed or heavily damaged in the earthquake last year had been
(C)  Some buildings that the earthquake destroyed and heavily damaged last year have been
(D)  Last year the earthquake destroyed or heavily damaged some buildings that have been

1．逻辑意思的合理性（一级排除 A, C )
 and/or 的选择，destroy/damage 不能同时发生。
逻辑意思决定了时态 ==》 construct 发生在 destroy 之前
时态的选择决定于 从句和主句的动作发生的先后。（排除 D )
Choices C and D use the present perfect tense incorrectly, saying in effect that the buildings have been constructed after they were destroyed last year.
 
2．改变句子中心（二级排除 E )
 时态选择与时间状语：
根据主从句的逻辑关系决定动作发生的先后，决定时态。
一般过去式的时间状语用时间点，如此题中的 last year. 完成时态用时间段做时间状语，通常用 since ….
时间状语的改变位置从从句到主句 会造成句子意思的改变，需要注意。
 --从句变成主句 或者 主句变成从句 都会改变句子的中心意思  选项D
 --时间状语的改变位置从从句到主句 会造成句子意思的改变，  选项E
Choice E suggests that the construction of the buildings, rather than the earthquake, occurred last year, thus making the sequence of events unclear.
句子中心不能改变 è D 改变了从句成主句， E 的时间状语改变位置造成了句子意思改变。
