1、過去分詞作前置定語(yǔ),放在它所修飾名詞前,相當(dāng)于形容詞的作用.例如：an organized trip,有組織的旅行,a broken cup 打破的茶杯,fallen leaves 落葉 a ploughed field 一塊犁過的田
2、過去分詞（短語(yǔ)）作后置定語(yǔ),相當(dāng)于一個(gè)定語(yǔ)從句,表示“被動(dòng)”或“完成”的意思.分詞作定語(yǔ)可以改成一個(gè)定語(yǔ)從句.例如：
1) I like the food cooked by my father 我喜歡爸爸做的飯
Cooked 在這個(gè)句子中就是過去分詞作后置定語(yǔ),這個(gè)句子可改成一個(gè)含有定語(yǔ)從句的復(fù)合句.如：
I liked the food which was cooked by my father.
2) Britain was the first country in the world to have a free health care system paid for by the government.
英國(guó)是世界上第一個(gè)由政府投資實(shí)行免費(fèi)健康保障體系的國(guó)家.
Paid for 在這個(gè)句子中就是過去分詞作后置定語(yǔ).它同樣可以改成一個(gè)含有定語(yǔ)從句的復(fù)合句.如：
Britain was the first country in the world to have a free health care system which was paid for by the government.
