Can you imagine the difficulty I^^^Can you imagine the difficulty I had __settling___ these problems?why "settled" can't?

问题描述:

Can you imagine the difficulty I^^^
Can you imagine the difficulty I had __settling___ these problems?
why "settled" can't?

__settling___ these problems修饰the difficulty I had
I 对于these problems是主动
所以用现在分词
have difficulty (in) doing
两种理解,还是看语感吧

这两个空分别填in和up
have difficulty in doing 做某事有困难 ,这是固定词组
settle up 解决

因为将句子还原后是I have the difficulty in doing
have difficulty/difficulties in doing sth
have (some) trouble in doing sth
这都是固定句型

in out
have difficulty in doing 做某事有困难
