问题描述：
This artist made up his mind to devote all he could_____ his English before going abroad
improing 我不太理解
答
to在这里是介词，devote …to sth. 而improving his English 是动名词做介词to 的宾语
答
devote to 将……奉献给；把……专用于
固定搭配，to后接v+ing形式
答
devote ....to doing sth 固定词组
答
devote ....to doing sth 致力于干什么
由于这个结构中的to 是介词，所以接动词时要用v-ing 形式
全句意为： 这个艺术家已下定决心在出国以前恶补英语
