Participles 分詞
1. 分詞的構成
分詞分為現(xiàn)在分詞和過去分詞。現(xiàn)在分詞構成為V+ing, 過去分詞構成為V+ed。分詞也有一般式、過去式、完成式及主動和被動等各種形式。
2. 現(xiàn)在分詞和過去分詞的區(qū)別
1) 在時態(tài)上，現(xiàn)在分詞表示正在進行，而過去分詞表示已經(jīng)完成。
Developing countries 發(fā)展中國家
The developed countries 發(fā)達國家
Boiling water 沸騰的水
Boiled water 開水
2) 在語態(tài)上，現(xiàn)在分詞表示主動，而過去分詞表示被動。
The oppressing class 壓迫階級
The oppressed class 被壓迫階級
Burning fire 燃燒的火焰
Burned skin 燒傷的皮膚
3. 分詞的時態(tài)與語態(tài)
1) 一般式（主動、被動）
分詞的一般式的主動式所表示的動作與謂語動詞表示的動作同時發(fā)生，或在謂語動詞表示的動作之前發(fā)生。其被動式表示這個動作正在發(fā)生或與謂語動作同時發(fā)生，主要充當定語、狀語或賓補。
E.g. I found him reading when I entered the room.
當我進入房間時我發(fā)現(xiàn)他在讀書。
I found the flowers watered. 我發(fā)現(xiàn)花已澆過了。
He found the matter being talked everywhere. 他發(fā)現(xiàn)到處都在談論這件事。
The building being repaired is a hospital. 正在修建的建筑物是一家醫(yī)院。
Being surrounded, the enemies were forced to put down their guns. 敵人被包圍，不得不繳械投降。
2) 完成式（主動、被動）
分詞的完成式表示分詞的動作發(fā)生在謂語動作之前。完成時態(tài)的分詞在句中常作狀語，一般不作定語。
E.g. Not having made adequate preparation, we postponed the sports meet.
由于沒做好充分的準備，我們推遲了運動會。
Having been given such a good chance, how could he give it up?
給了這樣好的機會，他怎能放棄呢？
3) 現(xiàn)在分詞的被動式與過去分詞的區(qū)別
過去分詞表示動作已完成，不強調(diào)時間概念，而現(xiàn)在分詞的被動式強調(diào)某一動作正在進行中。
E.g. The building repaired is library. 修建過的那個建筑物是我們的圖書館。
The building being repaired is our library. 正在修建的那個建筑物是我們的圖書館。
4) 延續(xù)性動詞和終止性動詞的現(xiàn)在分詞在時間含義上的區(qū)別
延續(xù)性動詞的現(xiàn)在分詞結構相當于一個過去進行時時態(tài)的句子，
而終止性動詞的現(xiàn)在分詞結構相當于一個一般過去時的從句。
E.g. Walking in the street the other day (=While I was walking in the street the other day), I came across an old friend of mine. 那天我在馬路上走時，突然碰到了我的一個老朋友。
Arriving at the airport (=When I arrived at the airport), I found my light had taken off. 到達機場時，我發(fā)現(xiàn)我的班機已經(jīng)起飛了。
4. 分詞的獨立結構
分詞（短語）作狀語時，盡管在形式上它沒有主語，但其邏輯上的主語必須和謂語動詞的主語保持一致。
E.g. Studying in the college (=When I studied in the college), I learned a lot from my teachers.在大學學習時，我從老師那里學到了很多東西。
但是，分詞有時也有自己獨立的邏輯上的主語，這種結構稱為分詞的獨立結構。它可以表示時間，原因，條件，伴隨的動作，有時還可用介詞with, without 來引導。
E.g. His mother being ill, he is absent today. 他的母親病了，他今天沒來。（原因）
Time permitting, they will start to do a new job. 如果時間允許，他們會開始做一項新工作。（條件）
He rushed into the room, his face covered with sweat. 他滿臉是汗地沖進了房間。（伴隨）
They traveled a whole day, without any food eaten. 他們餓著肚子旅行了一整天。（伴隨）
注意：分詞用于獨立結構時，如果分詞是沒有實際意義的being或 having been done形式時， being或having been可以省略。
E.g. The old man was in a bad condition, his temperature (being) over 40℃ and his pulse (being) weak and rapid. 那位老人處于不好的狀況，他的體溫超過40℃，脈搏既弱又快。
The report (having been) read, a discussion began. 讀完報告，開始討論。
The experiment (having been) finished, we left the lab and went home. 實驗結束后，我們離開了實驗室回家了。
