allow to do and allow doing 区别有50追分
能看明白,有个例子
说到位!
答的好有50!

首先我要说一下,你的问题本身有些问题,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.
allow既可作及物动词又可作不及物动词(多用于及物动词),
1）allow sb.to do sb.允许某人去做某事,
The doctor allowed him to smoke.医生允许他吸烟.
2）allow sb doing sth.允许某人做某事,可以表示当前可允许做的事或习惯性动作.根据上下文有时sb可以省略.如：
Is not allow (anyone)smoking in this meeting room.这间会议室里是不允许吸烟的.
类似的词还有:advise,forbid,permit,encourage等,如:
3) We advised him to have a good rest.我们劝他好好休息.
4) He advised going to Beijing for the holiday.他建议到北京去度假.
