Grammar
past participle (过去分词)
过去分词（past participle）是分词的一种。规则动词的过去分词一般是由动词原形加-ed构成，不规则动词的过去分词没有统一的构成规则，可以参考不规则动词表。过去分词在句子中一般可以用作定语、宾语补足语、表语和状语，但不能单独构成谓语。今天我们重点学习过去分词用作以下两种句子成分的用法：
1. 过去分词作定语
2. 过去分词作宾语补足语
过去分词作定语
一、意义
及物动词的过去分词作定语往往表示被动和完成；不及物动词的过去分词作定语不表示被动，只表示完成。
及物动词的过去分词表示被动和完成 a polluted river 一条被污染的河流
the watered flowers 浇过水的花
不及物动词的过去分词只表示完成，不表示被动 fallen leaves 落叶
the risen sun 升起的太阳

二、位置
单个的过去分词作定语时，通常放在所修饰词的前面 A watched pot never boils.

过去分词短语作定语时，通常放在后面，其作用相当于一个定语从句 The lady dressed in white is Lisa.
＝The lady who is dressed in white is Lisa.
穿白衣服那个女士是丽莎。
