be 动词后面加什么

关于be动词的特殊规则及其后面应该加什么文章:

  1. 当be动词用作连系动词时,后面应跟名词、代词或形容词作表语。例如:
    1. The flower is beautiful.
    2. She is my best friend.
  2. 当be动词用作助动词时,后面则应该加动词的过去分词形式,形成被动语态。例如:
    1. The book is being read by him.
    2. The car was repaired by a mechanic.
  3. 当be动词用来表示存在和发生时,后面通常不加任何的文章。例如:
    1. I am.
    2. They were at the party.
