(1)作状语用的过去分词(短语)和句子的主语之间有逻辑上的动宾关系，或称为被动关系。
(2)第一组句子中的过去分词(短语)分别在句子中作：①原因状语；②条件状语；③伴随情况或方式状语。
(3)比较第二组句子可知，作状语用的过去分词(短语)可以转化成相应的状语从句或并列句。 (4)从第三组句子可知，表示时间、条件、方式、比较或让步的状语，可用“从属连词＋过去分词”结构。可用于该结构中的从属连词有：when, once, while, if, unless, as if, as, than, though, although等。
一、过去分词作状语的类型
过去分词作状语，可以表示时间、让步、条件、原因、方式和结果，相当于一个状语从句。其逻辑主语为主句的主语，且与主句主语之间构成逻辑上的被动关系。

相当于时间状语从句。可在过去分词前加上连词“when, while, until”等，使其时间意义更明确。

当被问到对教学工作的观点时，菲利普说他觉得它既有趣又有意义。 2．作原因状语
相当于原因状语从句或并列句。

相当于条件状语从句。可加连词if, unless等转换成条件状语从句。 Used with care, one tin will last for six weeks. 如果用得仔细的话，一罐可以够用六周。 4．作让步状语
相当于让步状语从句。有时可加although, though, even if, even though, whether ... or等连词转换成让步状语从句。

＝ Although he was defeated by his opponent, he never gave up any hope. 尽管被对手击败，但是他从没放弃希望。 5．作方式、伴随状语 相当于and连接的并列句。 She accepted the gift, deeply moved.
＝ She accepted the gift, and she was deeply moved. 她接受了礼物，深深地被感动了。
[名师点津] 值得注意的是，有些过去分词(短语)因来源于系表结构，作状语时不强调被动而重在描述主语的状态。这样的过去分词(短语)常见的有：lost (迷路)；seated (坐)；hidden (躲)；lost/absorbed in (沉溺于)；dressed in (穿着)；tired of (厌烦)。

过去分词作条件、原因及时间状语时，通常放在句首；作伴随、结果状语时，通常放在句末；作方式状语时，一般放在句末，有时也放在句首；作让步状语时，一般放在句首，有时也放在句末。
