关于tpo23passage2的一个句子

mqcherryUID: 3505981

Importing the grain, which would have been expensive and time consuming for the Dutch to have produced themselves, kept the price of grain low and thus stimulated individual demand for other foodstuffs and consumer goods.
这句话怎么理解，还有从语法角度怎样运用了虚拟？would have与现在相反 为啥？
托福里面考虚拟的多么？
感激不尽！

我不懂虚拟不虚拟的语法，这里would have been讲的就是之前的情况expensive，与后面的low是相对应的。所以是 ...

好的~谢谢~我查了一下书，就是would have done就是和过去事实相反~多谢了！

首先 虚拟语气表示的都是和现实相反的
would have done是对于过去的虚拟语气 表示假如过去怎样现在就会怎样 “假如”后面的过去和真实的过去是相反的。
这句话里Importing the grain, which would have been expensive 因为which从句限定的是importing the grain，所以过去时刻肯定没有importing the grain.
