14．After the earthquake，the whole city _________．（ ）| A． | destroyed | B． | was destroyed | ||
| C． | had destroyed | D． | had been destroyed |
分析 地震过后，整个城市被破坏了．
解答 答案是B．考查被动语态，根据句意地震已经发生可以判断句子要用过去时，the whole city与动词destroy之间是被动关系，所以用一般过去时的被动语态，故答案选B．
点评 被动语态由"助动词be+及物动词的过去分词"构成．被动语态的时态变化只改变be的形式，过去分词部分不变．疑问式和否定式的变化也如此．掌握各种时态的被动语态是解题的关键．
