这是虚拟
从句用过去式,主句用would ,could,might,should 加动词原形,表示对现在,或者是将来的虚拟
如果我们能一直像12岁时那样精力充沛,那就需要大约700年,我们中的一半才会死去
明显两个动作都是假设的
第一,你现在不能像12岁那样精力旺盛
第二,后面那个也是不能实现的
言下之意是,只要你有本事一直保持12岁的体力,人们就能跟乌龟似得,活千年
为什么用could,是因为原来是can,这个虚拟的解释,上面已经说了,时态要后退一个时态,原来是can的,就用could
虚拟语气,表示难以实现的情况,此为与现在事实相反的虚拟语气。常用结构为条件句的谓语动词为were或动词的过去式,主句谓语用would|should|could|might+动词原行。
这里的 would 还有 could 都表示虚拟,想像出的情况,所以用would.
