allowdoingallowtodo区别？
因为英语中并没有allow to do sth这种结构，只有allow doing sth 及allow sb to do sth这两个结构。 你这样记忆可能方便一些：
1. 在主动语态中，如果allow后面没有sb出现在allow后面的话，就要接动名词形式；如果后面有sb做宾语，则必须要接to do sth.
2. 在被动语态中，只有sb be allowed to do sth的句式结构,而没有sb be allowed doing sth。 具有类似用法的动词还有： forbid sb to do sth / forbid doing sth advise sb to do sth / advise doing sth
