答案：1～3　CAB课堂互动探究过去分词作定语
过去分词是非谓语动词的一种形式,它既保留了动词的某些特征,又具有形容词和副词的特征.过去分词作定语,在语态上,表被动;在时间上,表示动作已经发生或完成,与它所修饰的名词有逻辑上的动宾关系.过去分词作定语时,所修饰的名词在逻辑上相当于被动句中的主语.作定语的过去分词一般由及物动词变来,因为只有及物动词才有被动意义.规则展示
1.过去分词作定语表示动作在谓语动作之前发生,已经完成并具有被动意义.有时也不表示时间性.
He is a teacher loved by his students.
他是个很受学生爱戴的老师.2．单个的过去分词作定语一般放在被修饰的名词之前。
We needed much more qualified workers.
我们需要更多的合格的工人。
My friend is a returned student.
我的朋友是个归国的留学生。3.过去分词短语作定语要放在被修饰的名词后面,作后置定语,其作用相当于一个定语从句.
The student dressed in white is my daughter.＝The student who is dressed in white is my daughter.
穿白色衣服的学生是我的女儿。
单个分词也可以作后置定语，用以强调动作。
They decided to change the material used.
他们决定更换使用的材料。4.如果被修饰的词是由every/some/any/no＋thing /body/one所构成的复合代词或指示代词those等时,即使一个单一的分词作形容词用,也要放在被修饰词的后面.
Is there anything unsolved?
还有没解决的问题吗？
There is noting changed here since I left this town.
自从我离开这个城镇以来，几乎没有什么变化。5．单个过去分词前加一名词或副词，常用连字符将它们连接起来构成一个复合形容词，放在其修饰的名词前，作前置定语。分词前加的名词表示分词的动作或行为主体，所加的副词表示方式、时间、程度、性质等意义。
This is a state?owned factory.
这是一家国营工厂。
This is our school?run factory.
这是我们的校办工厂。6．也有用不及物动词的过去分词作定语的情况，一般作前置定语，它不表示被动意义，只表示主动意义，强调动作完成。不能像及物动词的过去分词那样放在名词后面作定语。
