这个英语句子
He was busy writing the story,only breaking off occasionally to have a cup of tea.
意思是：他一直忙着写故事,只是偶尔停下来（break off）喝杯茶.
这里 break 为什么要用 ing 形式?是跟前面的 only
这个到底是什么结构呢?

only作形容词讲时,有一种用法是仅用于名词前,但是我觉得这个句子和这点没关.喝杯茶只是他一直忙着写故事中的一个动作,是一种伴随状态.所以用ing 形式.我记得表伴随是就必须用 ing 形式,表示同时发生.伴随状语是指状语从句的动作伴随主句发生,它的特点是：它所表达的动作或状态是伴随着句子谓语动词的动作而发生或存在的.简单说就是一个动作发生时同时伴随的动作或者状态.比如他笑着走进来.he came in,laughing.这里笑和走进来是同时发生的,但是比较之下强调的成分是走进来,而笑着就是附属的,是修饰成分.一般伴随的动作都是用动词的现在分词形式.主句动词不受影响.
