If given more time,I could have finished the task much better.为什么用given

问题描述:

If given more time,I could have finished the task much better.为什么用given

完整的是if i was given more time 该句是虚拟从句,从句省略了i was为什么 不能用gives me该题中if 引导的是对过去的虚拟而且题意是如果以前给我更多的时间,我现在就会更好地完成那件任务 还有根据could have finished 也可以看出来,该题要用虚拟时态
