sb be devoted to sth 献身于/专注于某事
devote sb to (doing) sth 使某人注意某事..
devote是及物动词 第一种形式主语是I的话 要是用第二种形式表达 就是 devote myslef to do 只是这个时间长了 就 不这么用了 可以把devoted 看成一个形容词
dedicated 努力工作的,专注的,投入的 = working hard at sth because it is important to you,是committed 的同义词; 从英语释义看指的是人的工作态度 They are dedicated to their work.
从英语释义看指的是人的devoted 挚爱的,忠诚的 = having great love for sb/sth and being loyal to them 从英语释义看指的是人的内在品质 They are devoted to their children/work.
be dedicated to / devoted to doing sth 都正确,只不过意思有区别。
