There are birds flying in the sky.
曹老师你好，后面的分词结构应该是定语，但也有人剖析为其它的成分，还麻烦老师剖析一下！谢谢!
Thereare birds flying in the sky.=There are birds which are flying in the sky.
解答：flyingin the sky为目前分词短语作定语，修饰前面的名词“birds”，等于定语从句“whichare flying in the sky”。
Thereare some boys playing games on the playground.=There are some boys who areplaying games on the playground
有的男生在操场上做游戏。备注：以上结构是“Therebe+名词+目前分词结构，名词是后面目前分词逻辑主语。”
