观察这两个句子，有什么区别：

状语从句：

Frightened by the loud noise, I went to see what was happening.

Step II. Grammar analysis

状语从句是如何变为过去分词做状语？

定义:相当一个状语从句，在主从句主语一致的条件下，省去从句中连词、主语和be动词而成。

观察下面两个句子，是否可以改为过去分词做状语

1. When it is seen from the top of hill, our school looks beautiful. 2. When Our school is seen from the top of hill, I find it looks beautiful. When Our school

is seen from the top of hill,

I

find it looks beautiful

主从句主语不一致

,不能省略从句主语和系动词。

过去分词做状语可做以下状语：

时间状语：when; while; after; before;

条件状语：if; unless 让步状语：although; even though/if 原因状语:

because 方式状语:

as if

伴随状语:

and 判断过去分词做什么状语，并改为对应的状语从句

1.Given more time, we could do it much better. ---If we were given more time, we could do it much better. 2.The teacher entered the classroom, followed by a group of students. ---The teacher entered the classroom and he was followed by a group of his students. 3.Written in a hurry, this article was not so good. ---Because it was written in a hurry, this article was not so good. 过去分词做状语与现在分词做状语的区别：

过去分词做状语是省去主语与be动词，因此逻辑上他们是被动关系

现在分词省去主语，只将谓语动词改为现在分词，逻辑上是主动关系。

Seen

(see)from the top of the hill, the city looks more beautiful. 2.
