探究点2 动词-ed形式作定语
动词-ed形式作定语时,表示的动作在谓语动词所表示的动作之前发生,已经完成并具有被动意义。此时,作定语的动词-ed形式一般是由及物动词转化而来,因为只有此类动词的动词-ed形式才有被动意义。
●不及物动词的动词-ed形式也可作定语,一般作前置定语,不表示被动意义,只强调动作的状态或完成。如：fallen leaves“落叶”；retired workers“退休工人”；the risen sun“升起的太阳”。
●动词-ed形式有时还可用作非限制性定语,相当于一个非限制性定语从句,前后用逗号分开。
Some of them, born and brought up in rural villages, had never seen a train.
他们中的一些人,出生并生长在农村,从来没有见过火车。
●动词-ed形式与动词-ing形式作定语时的区别:
动词-ing形式作定语时与所修饰的名词之间是逻辑上的主谓关系,表示动作正在进行；而动词-ed形式作定语时,则表示被动或完成意义。
The girl standing under the tree is really charming. 站在树下的那个女孩真的很迷人。
Mr Smith, tired of the boring soap opera, started to read a novel.
史密斯先生厌倦了无聊的肥皂剧,开始看起了小说。

注意:很多作表语的动词-ed形式已经具备了形容词的性质,如tired、 amused、 pleased等。
2.动词-ed形式作表语与被动语态的区别
动词-ed形式作表语表示主语的状态,常在be、 get、 remain等系动词后；而被动语态则表示被动的动作,由助动词be（有时也用get）加动词-ed形式构成,后面可由by引出动作的执行者。
The window is broken.
窗户破了。（表示状态）
The window was broken by Tom.
