因?yàn)檫^去分詞后置定語的話,表示的是與修飾的中心詞的被動(dòng)關(guān)系,而在本句中并無這種關(guān)系,所以不行.可以改為表示主動(dòng)關(guān)系的現(xiàn)在分詞,即：
people living in different countries made different languages.the leaves fallen to the ground are cleaned.這句話可不可以認(rèn)為是過去分詞后置定語表完成呢？為什么上一句就不行呢？后面這句的原句是定語從句吧：
the leaves which have fallen to the ground are cleaned.
而完成時(shí)態(tài)是不能做后置定語的，所以說the leaves fallen to the ground are cleaned.這句話并不符合英語語言習(xí)慣
