这个问题可以从语态上来区别:to do只能当allow用在被动语态的时候才能用,也就是只能是这种形式:
sb be allowed to do sth
He was allowed to drink some wine.
而allow doing 这种用法allow只能用在主动语态中,即:
sb allow doing sth
They allow our taking photo here.
从意义上来分别:
to do 结构中do的发出者是句子的主语(he);
doing结构中do的发出者不是句子的主语,而是另有他人(we).
楼上对的 补充一点 实际上没有allow to do这种形式(主动) 要牢记allow sb to do和allow doing的区别 中间有无sb很重要
