1. 过去分词作表语与被动语态的差异
I was surprised at the news.(系表) I was brught up by my aunt.(被动)
被动语态表示动作,强调被动关系, 绝大多数被动结构中的行为执行者可以由by引出。作表语用的过去分词表示主语的特点或所处的状态,这种结构中的过去分词前可加quite、very、rather等修饰词。
He is terrifying.(指他令人害怕)He is terrified.(指他感到害怕)Please describe a dg that is frightened.(狗受到了惊吓)Please describe a dg that is frightening.(狗是令人害怕的)
当表示主语处于某种状态,即“感到/觉得……”时,表语要使用过去分词; 而要表示主语具有“令人/使别人感到……”的特征/性质时,表语使用过去分词
2.过去分词与现在分词作表语的区别

区别表示情感意义的ing分词和ed分词
1.现在分词(V-ing)和过去分词(V-ed)作表语
用法：①现在分词作表语表示主语的特征(令人/使别人感到……)。 ②过去分词作表语表示主语的状态或者主观心理感受。注意：很多作表语的现在分词和过去分词都变成了形容词, 和系动词 (be, seem, remain, feel, lk等)连用， 或者用作定语修饰名词例句：The music is much (please) t the ear. I am very (please) t help yu.
