-ED分詞即我們平常所說的動(dòng)詞過去分詞。它有兩種形式：規(guī)則動(dòng)詞形式和不規(guī)則動(dòng)詞形式。規(guī)則動(dòng)詞形式由規(guī)則動(dòng)詞+-ED構(gòu)成;不規(guī)則動(dòng)詞有其特殊的-ED分詞。在語法功能上，它在句子中所能承擔(dān)的成分基本與-ING分詞相同，可以作表語，定語，狀語，也可以用在復(fù)合結(jié)構(gòu)中，不管它作什么成分，其最基本的含義是“被動(dòng)”的。-ED分詞在語法功能和意義上與-ING分詞有一定的區(qū)別。
I -ED分詞的用法
一、-ED分詞作表語
The glass is broken. / He was amused. / She seemed quite disappointed. / He is greatly discouraged by her refusal of inviting her to the party. / The window remains locked.
已經(jīng)形容詞化了的-ED分詞大都作表語，常見的有：accomplished, amazed, amused, astonished, broken, closed, completed, complicated, confused, crowded, deserted, devoted, disappointed, discouraged, dressed, drunk, exhausted, excited, experienced, fadded, fascinated, frightened, hurt, inexperienced, interested, known, learned, lost, married, pleased, puzzled, qualified, satisfied, surprised, tired, unprepared, unqualified, unkown, upset, worried, wounded等。
二、作定語的-ED分詞
-ED分詞可以作前置定語也可以作后置定語，作后置定語時(shí)相當(dāng)于一個(gè)定語從句

三、用作狀語的-ED分詞
這樣的-ED分詞通常來自及物動(dòng)詞。-ED分詞用作狀語時(shí)，跟-ING分詞作狀語時(shí)一樣，修飾主句的謂語動(dòng)詞，意義上相當(dāng)于狀語從句，表示時(shí)間，條件，原因，伴隨狀況等。-ED分詞結(jié)構(gòu)作狀語，前邊往往可以加when,while,if,as if,though。這時(shí)，我們可以把-ED分詞結(jié)構(gòu)理解為一個(gè)省略句，即省去了“主語和be的變化形式”。一般說來，這種結(jié)構(gòu)的邏輯主語必須與主句的主語一致。
