[总结]

过去分词可作定语、状语、表语和宾语补足语。过去分词作状语应注意以下几点：

一、过去分词作状语表示的意义

●表示时间(如例句1)、条件(如例句2)、原因(如例句3)、让步(如例句4) 的分词短语相当于相对应的状语从句。

After they had been discussed many times, the problems were settled at last.

If it is looked at from a distance, the painting seems much more beautiful.

Because I was caught in the rain on my way home, I had a bad cold.

Although it was built thirty years ago, the house still looks very beautiful.

●作方式状语或表示伴随情况，说明动作发生的背景或情况。一般情况下，分词所表示的动作和谓语动词所表示的动作同时发生。可转化成并列句。(如例句5-6)

The professor walked out of the hall and he was followed by his assistants.

She sat by the window alone, and she was lost in thought.

二、过去分词与句子主语之间的关系

●过去分词作状语表示被动或完成的动作。其逻辑主语一般应与句子的主语一致。过去分词与句子主语之间通常存在逻辑上的动宾关系。(如例句1-5)

【难点点拨】分词作状语时，用现在分词还是过去分词，取决于分词与句子主语之间的关系。主动关系用现在分词，被动关系用过去分词。比较：

Seeing from the top floor, we can find the garden more beautiful.

Seen from the top floor, the garden looks more beautiful.

●有些过去分词或短语来源于系表结构，或某些动词后面加-ed转化来的形容词，作状语时不表被动而表主语的状态。常见的有lost(如例句6), seated, hidden, lost in, dressed in, faced with, absorbed in, surprised, disappointed, exhausted, frightened, satisfied(如例句7), tired等。

三、“连词+过去分词”结构作状语

过去分词作状语时，可在分词之前加某些连词，以表示强调。常用的有if, unless, when(如例句8), once, until, though/ although, even if/ even though, as(如例句9), as if等。

【难点点拨】此结构实际是状语从句的省略形式。当状语从句的主语与主句的主语一致，且状语从句的谓语动词是被动式时，省略从句的主语和动词be即是。

Water can be changed into vapor when (it is) heated.

There is no point arguing about it, just do as (you are) told.

四、过去分词的独立主格结构作状语

如果过去分词的逻辑主语与句子的主语不一致，这种带逻辑主语的过去分词结构属于独立主格结构，作状语，表示时间、原因、条件、方式、伴随等(如例句10)。
