题目

关于虚拟语气的介词without
without the worker"s help ,sam _____ so much progress
A.would not make B would not have made
为什么选B、与过去事实相反
为什么与过去的事实相反，应该是与现在的事实相反啊。

答案

此句是"without"引导的含蓄条件虚拟句
工人的帮助是已发生的事实,此句是对在没有工人帮助下的虚拟.
Without the worker's help = If there hadn't been the worker's help
是对过去的虚拟.故主句用 would not have made 相应时态.
试比较
With her help(＝If I had her help),I would do the experiment well.假如有她帮助,我就可以把这个实验做好.
此句是对现在/将来的虚拟.
