BE Allow to Do

楼主你说的不太对.不太可能出现be allow,至少应该是be allowed.如果是我说的这样, 那么,前者是被动,做什么什么是被允许的,后者是主动,谁谁谁允许做什么.

be allowed to do 是被动语态 某人被允许做某事.allow doing 是主动语态 允许某人做某事.举个例子,比如说:Tom is allowed to play computer games. 汤姆被允许可以玩电脑游戏 Tom's father allows Tom playing computer games.汤姆的爸爸允许汤姆可以看电视. 不知道这样说 您明白没有 明白的话就请 呵呵~ 采纳一下

allow是“允许”的意思,“被允许”是被动,应该用allowed, be+过去分词才构成被动语态.而permitted就是过去分词,所以可以.

be allowed to do sth = allow doing sth 允许做某事祝你学习进步,更上一层楼!(*^__^*)

allow doing 允许做某事 The school allows taking mobile phones.allow sb to do sth 允许某人做某事,它的被动形式是:be allowed to do sth 某人被允许做某事如 The school allows the students to take mo

be allowed to do 表被动,allow sb to do sth表主动,allow doing sth 固定搭配

be allowed to do sth

I am allowed to study at a friend's house .我被允许在朋友家学习.

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,

allow sb to do sth. 允许某人做某事
