18．The fire was finally brought under control，but extensive damage _________．（ ）| A． | is caused | B． | was causing | C． | had caused | D． | had been caused |
分析 火灾终于被控制，但是巨大的损坏已经产生．
解答 答案是D．本题考查过去完成时；过去完成时强调"过去的过去"，题干中"damage"和"cause"之间是被动关系，且是在"火灾得到控制"之前，是过去的过去，故用过去完成时的被动语态，答案选D．
点评 对时态的选择，要在把握时态的基本用法的基础上，根据具体语境和题干中的时间推断时态，同时关注特殊的结构．
