书上说,含蓄虚拟条件句中,"主语的时态要求与含有条件从句的主语要求相同"这句话是什么意思?是指主句和从句都用相同的时态吗?比如这句“Einstein cared little for money,though he could have been very r
"主语的时态要求与含有条件从句的主语要求相同"这句话的意思是
主语的时态要求 与含虚拟条件句 对主句 的时态要求一样
也就是 与现在或将来情况相反 可以用 过去将来时（包括情态动词的过去式加原形动词）
与过去情况情况相反 可以用 过去将来完成时时（包括情态动词的过去式加have done）

从句虚拟过去when the accident happened，主句虚拟现在
这句是隐含条件...

一般情况下，虚拟条件从句和主句虚拟的时间应保持一致，但也有不一致的情况，这种情况叫复杂条件或错综条件句。
If he hadn't been rescued when the accident happened,he wouldn't recovered so soon now.
从句虚拟过去when the accident happened，主句虚拟现在
