the increasing population has become one of the most serious challenges in the world 中为什...
the increasing population has become one of the most serious challenges in the world 中为什么要用increase 的ing形式
加了ing就是形容词了吗为什么？

1、首先需要明确的是词性：increase是动词,increasing是形容词,increased也是形容词,这是固定用法,而不是人为加不加ing或是ed的问题；
2、此处population是名词,显然它前面需要的是一个形容词来对自己进行修饰,所以只能选择increasing或是increased；
3、我们知道,ing一般表示正在或是仍然在进行的动作,这个动作没有停止过,而是一直在持续进行中；而ed则象征着动作的结束或是完成；
4、此句表达的意思是人口在持续不断地增长,因此成为了一个严峻的问题；另外从现实来讲,人口的增长也是不可能停止的事情,所以我们只能选择increasing.
