★过去分词作状语，一是表被动的动作，二是表动作已经完成。

一般能作时间、原因、条件、伴随、让步和方式状语。

如：
1.表示原因，相当于由as, since, 或because引导的原因状语从句Caught in a heavy rain (Because he was caught in a heavy rain)
, he was all wet. 因为淋了一场大雨，所以他全身湿透了。

Greatly touched by the teacher’s words（Because the boy was
greatly touched by his teache r’s words）, he did a lot of things to help his classmates.
2.表示条件,相当于if, unless引导的条件状语从句
Given more time (If we were given more time), we could do it much better.
Compared with you(If we are compared with you), we still have a long way to go.
3. 表时间, 相当于when, while, until等引导的时间状语从句等. When it is seen from the hill（Seen from the hill）, the park looks very beautiful.
Don’t speak until you are spoken to（Until spoken to）.
4.表让步，相当于though, although，even if/though等引导的让步状语从句
Though warned of the storm（Though they had been warned of the storm）, the farmers were still working in the fields.
Even if invited (Even if I am invited), I will not take part in the party. 5. 表方式、伴随状语，相当于一个并列句。

The teacher entered the classroom, followed by a group of students （and he was followed by a group of students.）
The teacher stood there, surrounded by the students.(and was surrounded by the students.)
★Sum up:
1.过去分词在句子中可以作时间状语、原因状语、伴随状语、条件状语和让步状语等。

2.过去分词作状语表示被动或完成的动作,相当一个状语从句。

3.过去分词作状语时其逻辑主语与主句的主语要保持一致。

否则分词短语就要有自己的逻辑主语, 这种结构称为独立主格结构.e.g.:
All our savings gone, we started looking for jobs.
He rushed into the room, his face covered with sweat.
4. 位置：过去分词作状语，可以放在主句的前面或者后面，用逗号将二者隔开。

★重难点辨析（一）：主语一致
Seeing from the hill, you will find the city looks like a big garden. Seen from the hill, the city looks like a big garden.
★重难点辨析（二）：不表被动的特殊情况
1．有些过去分词因来源于系表结构，作状语时不表被动而表主语的状态,如：lost (迷路)；seated (坐); hidden (躲); lost / absorbed in (沉溺于/专注于);born (出身于); dressed in (穿着); devoted to(全神贯注于);faced with(面对) 等
2．由某些动词后面加-ed转化来的形容词也具有此用法。

如：frightened, satisfied, tired of, disappointed等。

Lost / Absorbed in deep thought, he didn't hear the sound.
Surprised at what had happened,Tom didn’t know what to do.
3.过去分词与现在分词作状语的区别：
注意：选择现在分词还是过去分词作状语，关键看主句的主语。

如分词的动作是主句的主语发出，分词就选用现在分词，反之就用过去分词。

例如：
Used for a long time, the book looks old.
Using the book, I find it useful.
总之，现在分词表主动、进行；过去分词表被动、完成。

Step4: Several minutes for them to revise what we have learnt in this class and ask if any question. Then, finish 10 related exercises on their coach book. (动)
