答
你好
used to do 过去常常
be devoted to working =devote oneself to do 致力于。。。
所以你说的2种情况都是可以的
答
应该两种都可以的吧
答
he used to devote himself to working hard
he used to be devoted to working hard
他过去常常很努力的工作
devote ...to 强调动作
be devoted to 强调状态
答
He used to devote himself to working hard.
devote...to... to是介词
因此后面动词要变成动名词形式
