This brief visit with Mother Nature cost me two days off from work,
recovering from a bad case of sunburn and the doctor's bill for my son's food
poisoning.
recovering from a bad case of sunburn and the doctor's bill for my son's food poisoning 这个现在分词短语是间接宾语me的非限制性定语,recovering 的逻辑主语为me。或者按照剑桥英语语法的观点把现在分词短语分析为补充语,对me作补充说明。
