答案：1～3　CBA课堂互动探究过去分词作状语
过去分词作状语主要是说明谓语动作发生的背景或条件;表示原因、时间、条件、让步、方式或伴随情况等.过去分词可置于主句前,也可置于主句后,用逗号与主句隔开.过去分词作状语可分为:一般式 (done) 表示分词动作与谓语动作同时发生或分词动作发生于谓语动作之前；完成式 (having been done) 强调分词动作发生在谓语动作之前。
过去分词作状语时的具体用法：规则展示
1.过去分词作时间状语相当于一个时间状语从句.例如：
Asked (When he was asked) what had happened, he lowered his head.
当被问到发生了什么的时候，他低下了头。2.过去分词作原因状语相当于一个原因状语从句.例如：
Frightened (＝Because / As she was frightened) by the tiger，the girl didn’t dare to sleep alone.
因为害怕老虎，这个女孩不敢单独睡觉。3.过去分词作条件状语相当于一个条件状语从句.例如：
Grown (If these seeds are grown) in rich soil,these seeds can grow fast.
如果种在肥沃的土壤里，这些种子能长得很快。
Given (If we were given) more time,we could do it better.
如果给我们更多时间的话，我们可以做得更好。
【注意】　此句中的given在许多语法书中作为介词处理.4.过去分词作让步状语相当于一个让步状语从句.例如：
Left (Although he was left) at home,John didn’t feel afraid at all.
虽然John被单独留在房间里，他一点都不害怕。
5.过去分词作状语表示伴随动作或状态.例如：
The teacher entered the classroom,(and he was) followed by a group of students.
老师进入教室，后面跟着一帮学生。【注意】　
1)过去分词做状语(表原因,让步,时间,结果……) 过去分词与主句的主语是动宾关系,即过去分词与主语是被动关系。
① The teacher came into classroom,followed by some students.
the teacher与followed 形成被动关系
句意为老师进入教室，后面跟了一些学生。
② The teacher came into classroom,following another teacher.
The teacher 与following 形成主动关系。2)过去分词的主语与从句的主语不一致,过去分词用独立的结构.其过去分词前面也要带上主语.
③All things considered,her paper is of great value than yours.
all things 和 her paper 不是同一个主语
从上面中,我们可以看到,things 与her paper 不是同一个主语，所以过去分词前的主语不能省略.规则运用
