二、过去分词作定语的意义
不及物动词的过去分词作定语，只表示动作已完成，不表示被动；及物动词的过去分词作定语，表示被动或完成。
1．不及物动词：只表示完成，不表示被动。
a ________(retire) teacher 退休教师
_________(fall) leaves 落叶
the _______(rise) sun 升起的太阳

the ________(break) glass
碎了的杯子
the question __________(discuss) yesterday 昨天讨论的问题
三、现在分词与过去分词作定语的区别
1．语态上不同：现在分词表示主动意义，过去分词多表示被动意义。
The woman __________(stand) beside him is his secretary. (the woman与stand之间是主动关系)
站在他旁边的那个女人是他的秘书。
She showed me the book ______________ (recommend) by the professor.(the book与recommend之间是被动关系)
她把教授推荐的书给我看了看。
2．时间关系上不同：现在分词表示正在进行的动作，而过去分词表示已经完成的动作。
the changing world 正在发生变化的世界
the changed world 已经变化了的世界
3．英语中有很多与感觉有关的动词其现在分词表示主动意义，即“令人……的”，多用来修饰物；其过去分词表示被动意义，即“感到……的”，多用来修饰人、人的声音或表情等。常用的这类词有：

exciting令人激动的
excited激动的，兴奋的
astonishing令人惊讶的
astonished 感到惊讶的
inspiring令人鼓舞的
inspired 受鼓舞的
disappointing令人失望的
disappointed感到失望的encouraging令人鼓舞的

【名师点津】　
有些使令动词，如dress, seat, absorb等，其过去分词无论作定语还是表语，都无被动的意味。因为dress oneself in等于be dressed in; seat oneself on等于be seated on; absorb oneself in等于be absorbed in。这种现象缘于反身代词的用法：主语和宾语同为一人，主语是动作的发出者，又是动作的承受者。这就出现了被动语态或过去分词不表示“被动”的语言现象。
四、过去分词、现在分词的被动形式与动词不定式的被动形式作定语的区别
done, being done, to be done三者均表被动含义，过去分词表示已完成的动作，现在分词一般被动式表示正在进行的动作，而不定式的被动式表示动作尚未发生。
The building _________(build) last year is our teaching building.
The building __________ (build) now is our teaching building.
The building ___________(build) next month is our teaching building.
