问题描述：
1.So many people went to watch the football match,_____to the winners.
A.shouted B.shouting C.shout D.to shout
2.I can't understand the letter______in English.
A.written B.writing C.write D.have been written
3.Among those_____were some classmates of mine.
A.invited B.inviting C.to invite D.been invited
答
1.A
因为这里shouting to the winners,是前面句子的伴随状语,要用分词形式,是主语so many people发出的动作“喊”,所以用主动语态的shouting,不用被动语态的shouted.
2.A
此处written in English是宾语the letter的宾语补足语,用分词形式,又因为信（letter）与写(write)是被动关系,所以选A.
3.A
这个句子是个倒装句,原顺序应该是：
Some classmates of mine were among those invited.
此处的invited 是修饰those的,是过去分词做定语,同样是因为存在被动关系,所以用了过去分词表被动.
希望说明白了,
