过去分词
1.过去分词基本构成：“动词原形+ed”.部分过去分词有特殊形式变化 。
2.过去分词不能单独用作谓语，过去分词保留着动词的部分特性，有完成或被动含义。在句法功能上，过去分词(短语)与形容词或副词作用类似，在句子中可充当定语、状语、宾补、表语等成分。
过去分词形式作定语
1.过去分词修饰名词或代词作定语，与被修饰名词构成逻辑上的动宾关系。通常表被动或完成。
2.过去分词作定语时一般位于所修饰的名词之前,过分分词短语通常位于所修饰的名词之后。
1.Don’t drink the polluted water.
2.Do you know the boy called Tom
过去分词做宾语补足语

被动

2. 少数不及物动词如 go, change, fall 等的过去分词作宾语补足语时，仅表示动作 _____。因此，宾语与过去分词之间不存在逻辑上的被动关系。
完成
