两者都是表示被动．
但前者可以充当句子的谓语结构，而后者则只能充当补语定语等修饰成分，不能构成谓语．如
The book is called Jane Eyre.(is called 是谓语)
I like the book called Jane Eyre very much.（called Jane Eyre是后置定语，句子的谓语是like）
1 分词作定语分词作定语时，单个的分词通常放在被修饰的名词之前，分词短语一般置于所修饰的中心词后面。现在分词修饰的是发出该动作的名词(即与名词有主谓关系)
More and more developing countries established strategic partnership with developed countries.
The young sitting between my sister and my brother is my cousin Jack……
2 在表示一个被动动作时，如果这个动作正在进行，或是与谓语表示的动作同时发生，我们可以用现在分词的被动形式。
