【归纳总结】
过去分词作表语主要表示主语的 或 等。
【注意】
过去分词作表语与被动语态的区别:
1.用作表语的过去分词被动意味很弱,主要表示动作的完成和状态,此时相当于一个形容词。
2.被动语态的过去分词被动意味很强,句子主语为动作的承受者,后面常跟by短语。
例子:
(1)The glass was broken.表示
The glass was broken by Tom.表示
(2)The windows are closed.表示
The windows are closed by Jack.表示
3.表示"感觉流露"的一些过去分词(如:interested,surprised,excited,frightened,shocked)和一些过去分词(如dressed,drunk,devoted,lost,known)常用作表语,表示状态。其中有些仅表示状态,没有被动意味。
