complements.

　　An object complement is a word or phrase that follows the direct object and modifies or completes its meaning. e.g.:

　　The cold water made Susan chilly.

　　The news reports named the explorer a hero.

　　A subject complement follows a linking verb (a verb such as to be, to seem, to appear, to feel) and modifies or renames the subject. A subject complement that is an adjective is termed a predicate adjective. e.g.:

　　The instructor seemed cheerful.

　　A subject complement that is a noun is also called a predicate noun or predicate nominative. e.g.:

　　My neighbor is the president of the PTA.

4. Learning about the past participle as the object complement

如果补语与宾语具有逻辑上的动宾关系, 宾补的动作具有"完成"概念,或宾补表示已经存在的状态,就用过去分词作宾补。常见的用过去分词作宾补的结构有:

　　keep / leave / have / get sth. done; find / see / discover / observe / notice / hear sth. done; make oneself done

　　e.g.: I have never heard the song sung in English.

　　Note:如果把上述结构变为被动语态, 则原来作宾补的过去分词变成主补。

　　e.g.: 1. The window was found broken.

　　　　2. The work was left unfinished.
