（三）過去分詞：

1、過去分詞的基本用法：過去分詞只有一種形式，也沒有主動(dòng)語態(tài)，它所表示的動(dòng)作是一個(gè)被動(dòng)的或是已完成的動(dòng)作。過去分詞在句中也可用作定語、表語、賓語或狀語等成分。過去分詞在句中作某種成分時(shí)，其邏輯主語一般為該分詞所表示的動(dòng)作的承受者，如：

（1）作定語：過去分詞作定語時(shí)，如果這個(gè)分詞是一個(gè)單詞，就位于其修飾的名詞之前，如果是分詞短語，就位于其修飾的名詞之后。被過去分詞所修飾的名詞，就是該分詞的邏輯主語，如：The stolen car was found by the police last week.

（2）作表語：過去分詞作表語時(shí)，表示其邏輯主語所處的狀態(tài)，其邏輯主語就是句中的主語，如：The glass is broken.這個(gè)玻璃杯是破的。 注：過去分詞作表語時(shí)，和動(dòng)詞的被動(dòng)語態(tài)結(jié)構(gòu)相似，但兩者表達(dá)的意義不同，如：The glass was broken by my little brother.這個(gè)玻璃杯是被我小弟弟打破的。作表語用的過去分詞在許多詞典中已列為形容詞，如：crowded, devoted, discouraged, done, dressed, drunk, experienced, frightened, gone, hurt, interested, killed, known, learned, lost, pleased, satisfied, shut, surprised, tired, undressed, worried, astonished, broken, completed, covered等。

（3）作賓語補(bǔ)足語：過去分詞作賓語補(bǔ)足語時(shí)，句中的賓語就是其邏輯主語，如：When I opened the door, I found the ground covered by fallen leaves. 注：動(dòng)詞have后的復(fù)合賓語中，賓語補(bǔ)足語如為過去分詞，常表示該分詞所表示的動(dòng)作是由別人來執(zhí)行的而不是句中主語自己來執(zhí)行的，如：I had my bike repaired yesterday. 昨天我（找別人）把我的自行車給修了。

（4）作狀語：過去分詞作狀語時(shí)，相當(dāng)于一個(gè)狀語從句，該結(jié)構(gòu)的邏輯主語一般都是主句的主語，是過去分詞所表示意義的邏輯賓語。為了使作狀語的過去分詞意義更加明確，常在分詞前加when, if, while, though, as等連詞，如：Seen from the hill/ When seen from the hill, our town looks beautiful.; Given more time/ If given more time, we could have done it better.（we是該結(jié)構(gòu)的邏輯主語，是give的邏輯賓語。）

獨(dú)立主格：上述-ing和過去分詞的用法中，-ing和過去分詞在句中均有邏輯主語，但有時(shí)它們也能有自己的獨(dú)立的主語，這種獨(dú)立的主語，一般為名詞或代詞，位于其前之前，和-ing或過去分詞構(gòu)成獨(dú)立主格。獨(dú)立主格在句中一般只作狀語用，而-ing和過去分詞作用的形式，則要根據(jù)它們所表示的動(dòng)作和句中謂語動(dòng)詞所表示的時(shí)間關(guān)系而定。至于獨(dú)立主格中是使用-ing或是過去分詞，則要根據(jù)它們的主語和其所表示的動(dòng)作的主動(dòng)被動(dòng)關(guān)系而定，如：The bell ringing, we all stopped talking. 注：The work having been finished, she sat down to have a rest. ①獨(dú)立結(jié)構(gòu)中的being或having been�？墒∪�，如：The meeting (being) over, all left the room. ②作伴隨狀語的獨(dú)立結(jié)構(gòu)�？捎脀ith短語來代替，如：She read the letter, tears rolling down her cheeks./ She read the letter with tears rolling down her cheeks.

2、-ing形式與過去分詞的區(qū)別：

（1）語態(tài)不同：-ing形式表示主動(dòng)概念，及物動(dòng)詞的過去分詞表示被動(dòng)概念。an inspiring speech鼓舞人心的演說；the inspired audience受鼓舞的聽眾。

（2）時(shí)間關(guān)系不同：現(xiàn)在分詞所表示的動(dòng)作一般是正在進(jìn)行中的動(dòng)作，而過去分詞所表示的動(dòng)作，往往是已經(jīng)完成的動(dòng)作，如：The changing world正在發(fā)生的世界；the changed world已經(jīng)起了變化的世界。
