一道简单的语法问题

there are mang boys playing the footballs

i think it must be teenagers having fun

这当中的playing having 前为什么不用加be动词,这涉及到什么语法知识?

动名词 放在名词后面 可视为定语从句

there are mang boys playing the footballs=

there are mang boys who is playing the footballs

动词ing形式,宾补?!

football前不用the
这表示的是补充说明所以不用be,不然一个句子里就有两个谓语了
