非谓语动词的答案
1.can i smoke here?
sorry,we don't allow __here .
a.people smoking b.people smoke c.to smoke d.smoking
2.the children talker so loudly at dinner table that i had to struggle__
a.to be heard b.to have heard C.hearing D.being heard
3.what worried the child most was__to visit his brother in hospital
A.his not being allowed B.his not allowing C.his being not allowed D.having not been allowed
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
收起
1.C
allow to do sth
2.a
struggle to do sth,不定式的被动结构
3。a
也是一个被动语态结构。
