would have been为什么不能用在这里?
问题描述：
would have been为什么不能用在这里?
Without electricity human life ________ quite different today.
A.is B.will be
C.would have been D.would be
答案为什么是D而不是C?
would have been不是应该表示应该发生而没有发生的事情吗?
用在这里怎么不对?
答
would have been表示的是对过去的虚拟,而 would be 则是对现在或将来的虚拟,本句的意思是“如果没有电,人类现在的生活会是大不相同的”,这里指的就是目前的情况,所以只能用would be.
