1.D
allow doing sth.允许某事
allow sb.to do sth.允许某人做某事
符合该两种用法的只有D,所以D正确
2.A
struggle to do sth.努力、奋力做什么事
这里句意需要使用动词不定式的被动,前面是：孩子子在餐桌上说话声音太响了,以至于我不得不努力（听见）,是听见人家说话,还是努力被人听见,是努力使自己被人家听见,所以是被动语态,to be done,所以A正确
3.A
先要知道句意：孩子最担心的事是,（）去医院看哥哥.根据上下文意思是,他没有被允许去,所以用allow的被动时,这里还要注意,他没有被允许去看,在句子中的成分是表语,在was后面嘛,不能直接用动词形式,这件事,是一个名词性质,所以用动名词,动名词相当于名词,可以说谁的,就跟名词一样,his book/his doing,被动形式是：his being done,not否定词加在being前构成否定形式,所以是 his not being allowed,所以A正确

1. d.smoking. allow + doing sth. 表示允许做某事，固定用法 /allow sb to do sth, 表示允许某人做某事，固定用法
2. b.to have heard hear和主语-我是一个主动的关系，不能用被动
struggle to do sth 挣扎着做某事，努力做某事
struggle for （为……而努力）或者struggl...

1. d.smoking. allow + doing sth. 表示允许做某事，固定用法 /allow sb to do sth, 表示允许某人做某事，固定用法
2. b.to have heard hear和主语-我是一个主动的关系，不能用被动
struggle to do sth 挣扎着做某事，努力做某事
struggle for （为……而努力）或者struggle against （与……作斗争）.
3. A.his not being allowed
the child和allow在本句中，是一个被动的关系，是被允许。另外，动名词做主语或者宾语的时候，动名词的否定形式是在动名词前面直接加not。这边不需要用完成时间，只是交待说：不被允许去医院看望他的哥哥这件事，不涉及到完成的时态

2.a
struggle to do sth,不定式的被动结构
