过去分词作形容词如果想表示完成,应当怎么用?比如说：leaves which have fallen = fallen leaves 那么a boy who has eaten a banana = 不用关系代名词应该怎样表现表示完成的过去分词作形容词fallen一个字的形容词放在名词前,eaten a banana两个字的形容词就要放名词后吗?定语就是形容词片语或者形容词子句吧,不过就是两个字以上的形容词所以放在了名词后面.leaves which have fallen 是关系代词做定语从句,如果不用关系代词which have 就只剩下过去分词fallen 因为它是一个字所以放在名词前,所以就是fallen leaves.而a boy who has eaten a banana如果不用关系代词who has就只剩下eaten a banana所以我不知道它怎样形容a boy,a boy wearing a coat 等于a boy who is wearing a coata boy ha

比如说：leaves which have fallen = fallen leaves
那么a boy who has eaten a banana = 不用关系代名词应该怎样表现
表示完成的过去分词作形容词fallen一个字的形容词放在名词前,eaten a banana两个字的形容词就要放名词后吗?
定语就是形容词片语或者形容词子句吧,不过就是两个字以上的形容词所以放在了名词后面.leaves which have fallen 是关系代词做定语从句,如果不用关系代词which have 就只剩下过去分词fallen 因为它是一个字所以放在名词前,所以就是fallen leaves.而a boy who has eaten a banana如果不用关系代词who has就只剩下eaten a banana所以我不知道它怎样形容a boy,
a boy wearing a coat 等于a boy who is wearing a coat
a boy having eaten a banana 等于a boy who is having eaten a banana
我是这样的逻辑,having eaten a banana和主词有be动词的关系,否则我不知道为什么having eaten a banana可以作定语
