can you imagine the difficulty the government had _ the villagers to leave here为什么用persuading

这是have difficulty (in) doing sth "做某事有困难“的句型

不管采不采纳,我的回答就在这里
这里先要把定语从句：the government had ,去掉,然后,句子简化为：
can you imagine the difficulty,persuading the villagers to leave here
然后,你就发现,这个persuading 现在分词,是做伴随状语的,逻辑主语是i ,i和劝说之间是主动关系
就相当于,这样一个状语从句：
when i persuade the villagers to leave here,i can imagine the difficulty.
但是,现在发现,我这个回答,有个错误,就是逻辑主语找错了,逻辑主语,是*,而不是你我
这个句子的结构,其实是这样的：
Can you imagine the difficulty the government had persuading the villagers to leave here?
= The government had difficulty(in) persuading the villagers to leave here,and can you imagine it?
*在劝说村民离开这里的时候,遇到的困难有多大,你能想象得到吗?
