很多同學都學過狀語和分詞，那么分詞作狀語是什么？小編整理了一些相關英語語法，大家一起來看看吧。

分詞作狀語用法

分詞或分詞短語作狀語，指的是直接將分詞或分詞短語放在句首、句中或句末作狀語。需要注意的是，分詞短語的邏輯主語必須要與句子的主語一致。

一、過去分詞(短語)作狀語時，其邏輯主語通常就是句子的主語。過去分詞(短語)作狀語一般都用逗號同其它成分隔開。

1. 作時間狀語時，可轉換為when或while等引導的從句，通常放在句首。如：

Seen from the top of the hill (= When it is seen from the top of the hill), the school looks like a big garden.

2. 作條件狀語時，可轉換為once, if或unless等引導的從句，一般放在句首。如：

Given more attention (= If it was given more attention), the fire could have been avoided.

3. 作原因狀語時，可轉換為because, as或since等引導的從句，多放在句首。如：

Encouraged (= As she was encouraged) by the teacher, the girl was very happy.

4. 作讓步狀語時，可轉換為though, although 或even if引導的從句，常放在句首。如：

Left (= Although she was left) alone at home, Jenny didn’t feel afraid at all.

5. 作方式或伴隨狀語時，常可轉換為并列分句，可位于句首或句末。如：

Surrounded by his students, the teacher went into the lab. (= The teacher was surrounded by his students and he went into the lab.)

6. 過去分詞(短語)作狀語時，有時為了強調，前面可帶連詞when, while, if, though, as if, unless等。如：

When given a physical examination, you should keep calm.

二、現在分詞與過去分詞作狀語的區別

現在分詞作狀語與過去分詞作狀語的最主要區別就在于兩者與所修飾的主語在邏輯上是主動還是被動關系。

1. 現在分詞作狀語時，現在分詞表示的動作與主語之間在邏輯上是主動關系。如：

Not knowing what to do, he asked his good friend for help.

2. 過去分詞作狀語時，主語是過去分詞動作的承受者，它們之間是被動關系。如：

Given more attention, the flowers could have grown better.

分詞用作原因狀語

Being athletic, Tom found the climb quite easy. 由于身體健壯，湯姆覺得爬山很容易。

His car broken down, he had to walk. 他的車壞了，所以只好走路。

Much discouraged, she moved on to London. 她很沮喪，搬到了倫敦。

【說明】分詞(短語)用作原因狀語通常可轉換成由as, because, since, now that 等引導的原因狀語從句，如上面三句也可轉換成：

As she was very weak, she couldn’t move.

As he was athletic, Tom found the climb quite easy.

Because his car broken was down, he had to walk.

Because she was much discouraged, she moved on to London.
