devote to (doing) sth. to...有两种词性：一是“不定式符号”，表明后面是一动词（原形），即我们常见的：to do sth.二、更多的时候，to 是一个普通的“介词” （doing) sth (noun or pron)一说你就知道：e.g. Let's to to school.He'll come to the company...How can I get to the museum?这些句子中的to 都是你熟悉的介词，当它后跟名词或代词时，你没有觉得什么特别的。但如果遇到动词，就要将 do sth 改成 doing sth，因为道理很简单，动词不能做介词宾语。类似的常见短语中含介词 to (doing)sth：pay attention to doing....be used to doing... contribute to doing...be dedicated to doing = devoted, look forward to doing...., etc.
或者你可以记住这种固定用法。至于下面这道估计你困惑于时态。那么请看这句话后面的cared这个作为动词用了过去时，说明这是说的一个过去的状态，所以devote在这要用devoted

devote sth to doing 把某物奉献于做某事，to 是介词, 后跟动名词。不是不定式。
devoted作mr Wang的谓语，表过去时态。
