  【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。

  (1)How did the audience receive the new play?

  Well,his father seems pleased with his results.
