3、分词作定语1.作定语的过去分词一般是由及物动词转化的,被修饰的词逻辑上是这个及物动词的宾语。The government decided to rebuild the damaged bridge.政府决定重新修建那座被损毁的桥。Whats the language spoken in Germany?在德国,人们讲什么语言?2.不及物动词的过去分词也可作定语,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。Autumn is here,and the ground is covered with fallen leaves.秋天到了,地上铺满了落叶。When payments to

4、retired workers are cut,the three decide to get their money back.当给退休工人的退休金被削减之后,这三个人决定把自己的钱拿回来。3.过去分词短语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（=who were born and brought up in rural villages）,had never seen a train.他们中的一些人在农村出生和长大,从来没有见过火车。4.过去分词与动词-ing

5、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主谓关系,表示动作正在进行;而过去分词作定语时,则表示动作的被动或完成。The girl standing under the tree is really charming.正站在树下的那个女孩子真的很迷人。What do you think of the meeting held yesterday?你觉得昨天召开的会议怎么样?探究点2 过去分词作宾语补足语1.感官动词（短语）see、watch、observe、look at、hear、listen to、find、feel、notice等接过去分词（短语）作宾语补足语时,表
