    【语法总结】
    过去分词作定语和表语
    一. 过去分词作表语 
    作表语用的过去分词表示主语的特点或所处的状态,相当于形容词,强调主谓关系;被动语态表示动作,强调动宾关系,绝大多数被动结构中的行为执行者还可以用by短语来表示。 
    1. 过去分词做表语与被动语态的差异:      
    The store is now closed.(系表)  
    The library is usually closed at 8:00 p.m. (被动)      
    2. 某些过去分词作表语,多半用来表示人物所处的心理状态或情感变化, 其主语主要是人。  
    这类过去分词通常为下列过去分词: delighted, devoted, discouraged , astonished, frightened, excited, inspired, encouraged, interested, contented, pleased, puzzled, satisfied, tired, worried, ect . 
    二. 过去分词作定语
    作定语的过去分词相当于形容词,其逻辑主语就是它所修饰的名词。及物动词的过去分词作定语,既表被动又表完成;不及物动词的过去分词作定语,只表完成。
    1. 过去分词用作定语,如果是单个的,置于其所修饰的名词之前。
    We must adapt our thinking to the changed conditions. 
    我们必须使我们的思想适应改变了的情况。
    2. 过去分词短语用作定语时,置于其所修饰的名词之后,其意义相当于一个定语从句,但较从句简洁,多用于书面语中。
    The concert given by their friends was a success.
    他们朋友举行的音乐会大为成功。
    3. 过去分词短语有时也可用作非限制性定语,前后常有逗号。
    The meeting,attended by over five thousand people,welcomed the great hero. 
    他们举行了欢迎英雄的大会,到会的有五千多人。
