下面这句话为什么用were packed with,而不用was packed with?
It has been estimated that if the bridge were packed with cars,it would still only be carrying a third of its total capacity.

If 引导的非真实条件句,我们们虚拟语气.三种对应的结构如下：
如果是对固去的情况非真实假设
if 从句里 had done (过去完成形式),结果句 would have done
如果是对一般性事理的,或目前处境,非真实假设
if 从句用 did (动词的过去式,如果是be动词,那么只用were),j结果句 would do .楼主给的句子属于这个情况
如果是对将来的非真实假设
if从句用should +do,结果句 would do
