You can't imagine what difficulty we had walking home in the snowstorm
这里的walking是非谓语,
答
YES!What difficulty we had,宾语“我们遇到的困难” ,walking 作时间状语 当我们步行回家的路上现在分词作状语不是表示“正在”的意思吗？解释不通吧，这里是动名词吧？have difficulty (in) doing sth此处为动名词， have difficulty in doing sth , doing 动名词短语做介词in 的宾语，表示“在做某事的过程中”。我想如果这个句子，是其他和HAD搭配 不是difficulty 就没有了固定搭配，上面我的解释是通用的解释。
