初中英语问题,allow to do 和 allow doing sth到底该怎么区别?

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)。

(1)allow作“允许”或“许可”讲,常搭配用动词不定式短语作宾语补足语,即allow sb. to do sth.允许某人做某事。
如:Please allow me to carry your bag.请让我替你拿包。
My boss doesn't allow me to use the telephone.我的老板不允许我用电话。
We were allowed to smoke in this room only.我们只许在这间屋子里抽烟。
(2)allow作“许可:允许”将,只可搭配动名词短语作宾语,不可直接搭配动词不定式做宾语,即只可说allow doing sth.,不可说allow to do sth.。
如:They allowed smoking in this room only.他们只允许在这间屋子里抽烟。
Smoking is not allowed here.此处禁止吸烟。
(3)allow还常与out,in,up等副词搭配使用,即allow sb. in/out/up等。
如:She won't allow the children in until they've wiped their shoes.直到孩子们把鞋擦干净,她才让他们进来。
She is not allowed out after dark.天黑后,她不准出去。
