问题描述：
A group of young men are standing near a river ,（）for while-water rafting down the river
Abusy prepared
Bbusily preparing
Cbusily prepared
Dbusy preparing
答
选B
作状语表伴随行为,再如：He is standing there,waiting for a bus.
为什么选ing形式--- prepared指准备好了的状态,preparing指正在准备 强调动作,从修饰词busily(忙碌地）可见,这里强调行为,动作,而非状态,故用现在分词
为什么用busily---因为修饰动词要用副词,这里是修饰prepare.busy 是形容词,busily是副词
