loading分词作后置定语
所谓“定语”，就是能起到修饰、限定、解释说明作用语言，例如，形容词是定语，定语从句也是定语。由于一些分词或分词短语置于被修饰对象后面，所以称作“后置定语”。
现在分词和过去分词都可以做后置定语。
（1）被修饰名词与作定语动词为主动关系，表示该动作正在进行或与主句动作同时发生，或是经常发生行为时，用现在分词做定语。例如： The girl standing there is my sister. 站在那里女孩是我姐姐。 The people waiting for the bus are talking with each other. 正在等公车人们在相互交谈。
注意；分词短语作后置定语时可以改写成定语从句。 The girl who is standing there is my sister.
The people who are waiting for the bus are talking with each other. （2）如果名词与作定语动词为被动关系时，则定语有下列三种形式： a. 如果动作已发生或经常行为，用done。
例如：The house built there is mine. 建在那儿房子是我。 转为定语从句：The house which was built there is mine. b. 如果动作正在进行，用being done。
例如：The house being built there is mine.正在那儿建造房子是我。 转为定语从句：The house which is being built there is mine.
c. 如果动作未发生，用to be done。
例如：The house to be built there is mine.将要在那儿建起来房子是我。
转为定语从句：The house which is to be built there is mine.
