As a young man,he saw the great need for increasing the rice output.为何这句话的increaseing用ing
在这里是介宾短语,need后面用for没有疑问吧?for后面用动名词形式.这个记住就行,for 作介词后面都是动名词形式.
希望对你有所帮助,

前面有介词for

因为for 是介词,介词后面的动词用ing形式。

介词for后面要加名词,increasing是increase的动名词形式,可以算成是名词,所以这样就很好的解决了for后面要加名词的问题。还有,increase加 ing 时e要去掉。

表示一直持续的状态。
