一道语法题目请教，谢谢

Ironically, sails were the salvation of many steamships ____  mechanical failures.

b) suffered.                d). that had suffered

想问B和D有什么区别呢？

jeff2003

发生时间上的区别：B的主、从句的两个动作同时发生；D的从句的动作发生在主句之前。

另外，我觉得 suffered是过去分词修饰steamships，与steamship是被动的关系，如补全应为that had been suffered.而 that had suffered则是主动的关系。所以我觉得应该选that had suffered.
