　　過去分詞作狀語知識點歸納

　　過去分詞作狀語用法歸納

　　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 thehill (= When it is seen from the top of the hill), the school looks like a biggarden.

　　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 wasencouraged) 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 wasleft) alone at home, Jenny didn’t feel afraid at all.

　　5. 作方式或伴隨狀語時，?？赊D換為并列分句，可位于句首或句末。如：

　　Surrounded by hisstudents, the teacher went into the lab. (= The teacher was surrounded by hisstudents 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 physicalexamination, you should keep calm.

　　二、現在分詞與過去分詞作狀語的區(qū)別

　　現在分詞作狀語與過去分詞作狀語的最主要區(qū)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.

　　用括號內所給單詞的適當形式填空。

　　1. (tell) thathis mother was ill, Li Ming hurried home quickly.

　　2. (satisfy)with what he did, the teacher praised him in front of his classmates.

　　3. (give) a fewminutes, I’ll finish the experiment.

　　4. (compare)with Susan, you still have a long way to go.
