2、动词的被动形式:The letter has been opened! 信被人拆开了。He was said to have been arrested. 据说他被捕了。2)用作表语:I am awfully worried. Daddy is ill.我很着急,我爸爸病了。3)用作定语:She had a worried look on her face. 他满面愁容。4)构成复合宾语:She wanted the work finished by Friday. 他要求这工作星期五前完成。5)作状语:Aroused by the crash, he leapt to his feet. 他

5、on they were surrounded by bandits.The room is deserted. She has been deserted by her husband.be+表语结构都包含be或其他系动词加过去分词,而被动结构必须与其对应的主动结构在时态上一致。例如右边例句的主动结构(Her husband has deserted her.)和它们在时态上是一致的。注:有些带-ed结尾的词,并不是过去分词,而是由名词变化而来的形容词:As an artist, she is quite gifted. 作为画家,她很有天赋。3、过去分词做定语1) 有很多过去分词可用作定语
