3. Scientists say there are now fewer than 2,000 pandas living in the remaining forests.
本句中living in the remaining forests为现在分词短语，修饰名词pandas。
分词短语作定语时，应置于被修饰名词之后。例如：
The man standing by the window is our teacher.
站在窗边的那个人是我们老师。
（standing by the window就是一短语，也就是说不是一个单词，在此作定语表主动）
Suddenly there appeared a young woman dressed in green.
突然出现一个穿绿色衣服的女青年。
（过去分词短语作定语表被动或完成）
【注意】
区别：现在分词作定语表示动作正在发生或与谓语动作同时（或基本同时）发生，表示主动意义；及物动词的过去分词作定语表完成或被动的动作；不及物动词的过去分词作定语只表完成不表被动的动作。例如：
They lived in the house facing the south.
他们住在朝南的房子里。(现在分词作定语表示主动意义)
The meeting held yesterday is important.
昨天开的会议很重要。（及物动词的过去分词表被动或完成）
(2)分词短语作定语相当于一个定语从句，修饰前面的名词。例如：
The man reading a novel at the desk is my father.（现在分词表“主动、正在”）
= The man who is reading a novel at the desk is my father.
在桌边读小说的人是我父亲。
Is there anything planned for tonight? （过去分词表“被动、已经”）
= Is there anything that has been planned for tonight?
今晚有什么活动吗？
