內 容 提 要
-ED分詞即我們平常所說的動詞過去分詞。它有兩種形式：規則動詞形式和不規則動詞形式。規則動詞形式由規則動詞+-ED構成;不規則動詞有其特殊的-ED分詞。在語法功能上，它在句子中所能承擔的成分基本與-ING分詞相同，可以作表語，定語，狀語，也可以用在復合結構中，不管它作什么成分，其最基本的含義是“被動”的。-ED分詞在語法功能和意義上與-ING分詞有一定的區別。
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，作后置定語時相當于一個定語從句

三、用作狀語的-ED分詞
這樣的-ED分詞通常來自及物動詞。-ED分詞用作狀語時，跟-ING分詞作狀語時一樣，修飾主句的謂語動詞，意義上相當于狀語從句，表示時間，條件，原因，伴隨狀況等。-ED分詞結構作狀語，前邊往往可以加when,while,if,as if,though。這時，我們可以把-ED分詞結構理解為一個省略句，即省去了“主語和be的變化形式”。一般說來，這種結構的邏輯主語必須與主句的主語一致。
