Devoted to
此题考察过去分词作原因状语的情况.原句可还原成 原因状语从句：As he was devoted to his family,peter never missed a chance to get together with them on important occasions.因为皮特很爱他的家人,他会抓住每一个重要的日子来和家人团聚.因前后主语一致都是“Peter",因此可将" As he was "省略,留下“devoted to"作原因状语.
devote 的搭配是：sb is devoted to （doing) sth 意思是 某人热爱/致力于（做)某事
再举个例子：Seen from plane,our village looks beautiful.(see) 原句可还原是：when it is seen from plane,our village looks beautiful.从飞机上俯瞰,我们的村庄很漂亮.前后主语一致,都是村庄.所以省去“when is is ",留下过去分词短语作时间状语.
