I would have had to have been watching the game.中的have to
I would have had to have been watching the game.中的have to "Had to" is used here for what,obligation or probability? 是别人问的.我很奇怪have to还可以分为:obligation和probability表达,采纳答案是probability,但假若obligation理解成“必须,不得不,一定得”,那么probability是如何理解的?解释清楚即可,
这句话是个虚拟语态,所以才会用到have had to have been 的结构。had to 是have to 的过去形式,之所以变成had to,是因为其前面还有个have这个表示完成时的词。所以 Had to is used here for substitution of probability. 不知道我的表述你是否明白。
