　　過(guò)去分詞作狀語(yǔ)用法歸納

　　一、過(guò)去分詞(短語(yǔ))作狀語(yǔ)時(shí)，其邏輯主語(yǔ)通常就是句子的主語(yǔ)。過(guò)去分詞(短語(yǔ))作狀語(yǔ)一般都用逗號(hào)同其它成分隔開(kāi)。

　　1. 作時(shí)間狀語(yǔ)時(shí)，可轉(zhuǎn)換為when或while等引導(dǎo)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(yǔ)時(shí)，可轉(zhuǎn)換為once, if或unless等引導(dǎo)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(yǔ)時(shí)，可轉(zhuǎn)換為because, as或since等引導(dǎo)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(yǔ)時(shí)，可轉(zhuǎn)換為though, although 或even if引導(dǎo)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(yǔ)時(shí)，?？赊D(zhuǎn)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(guò)去分詞(短語(yǔ))作狀語(yǔ)時(shí)，有時(shí)為了強(qiáng)調(diào)，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(xiàn)在分詞與過(guò)去分詞作狀語(yǔ)的區(qū)別

　　現(xiàn)在分詞作狀語(yǔ)與過(guò)去分詞作狀語(yǔ)的最主要區(qū)別就在于兩者與所修飾的主語(yǔ)在邏輯上是主動(dòng)還是被動(dòng)關(guān)系。

　　1. 現(xiàn)在分詞作狀語(yǔ)時(shí)，現(xiàn)在分詞表示的動(dòng)作與主語(yǔ)之間在邏輯上是主動(dòng)關(guān)系。如：

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

　　2. 過(guò)去分詞作狀語(yǔ)時(shí)，主語(yǔ)是過(guò)去分詞動(dòng)作的承受者，它們之間是被動(dòng)關(guān)系。如：

　　Given more attention,the flowers could have grown better.

　　用括號(hào)內(nèi)所給單詞的適當(dāng)形式填空。
