真诚的麻烦各位英语高手帮我解答下这句英语

he went off immediately to visit him, carrying with him in his pocket 【what remained of a bottle of medicine】 formerly prescribed for an indisposition of Mrs.这是新概念英语第四册28课中的一句！大概意思就是说…他立刻动身去看望他！在他口袋里随身携带了从前为她妻子的一种小病，抓的还没有吃完的一瓶药！这里面的what到底什么意思呢？？？？当然肯定不是疑问词！希望各位朋友帮我解答的详细点，拜托了！

Answer 1

这个从句应该这样说就相对好理解一些，carrying what remained of a bottle of medicine in his pocket with him 他口袋里带着一瓶没吃完的药。 由于what后面句子比较长，所以原文才放到整句话的最后面。

这里的what用法是宾语的一部分，就类似于这句话what的用法一样 I take back what i said (我收回我刚才说的话)

Answer 2

carrying with … of Mrs. Carlyle's为现在分词短语作伴随状语。carrying的宾语为what引导的从句，类似carry sth with sb结构。of a bottle of medicine作what remained的定语。formerly prescribed for anindisposition of Mrs. Carlyle's作a bottle of medicine的定语。

Answer 3

个人认为：carrying +宾语从句（宾语从句前省略了that，这个从句是what remained of a bottle of ...）。如果remain是修饰what，那么应该是 carrying what remaining of a bottle of ... 。
remain of 的用法是 “东西+remain of+地点”。
