过去分词在雅思阅读中作后置定语的情况简直如of，on等介词在一篇文章中出现的情况一样多，这一知识点不仅不能忽视，还应该熟练掌握。
先来举几个过去分词的例子：
1.This is the book recommended by the teacher.
2.The person invited to the conferenceis my old friend.
3.The vase broken by my sonhas been swept away.
根据上面三个例句，如果将划线的部分去掉，并不影响整个句子语法的正确性，可见，划线部分的作用是修饰补充，有了它们，句子更具体，没有它们，句子也不是错误的。
是的，划线部分就是“过去分词作后置定语”，其所充当的作用就定语的作用，只是后置了。
过去分词作后置定语的表现形式：名词+ v-ed
特点：放在被修饰名词后(要不也不会叫后置了)
作用：表示被动，即这个过去分词与它前面的名词是被动的关系(大家可以再次体会下上面三个例句)
需要大家注意的是，千万不要把句子里的“过去分词”当成是该句的谓语动词!此外，老师还需要大家注意的是，“过去分词作后置定语”相当于一个被动语态的定语从句。
大家可以把上面三个例句转换成定语从句的形式：
1.This is the book that isrecommended by the teacher.
2.The person who isinvited to the conference is my old friend.
3.The vase that wasbroken by my son had been swept away.
大家可以再次体会一下~
