问题描述：
英语翻译
The Antarctic is a continent almost as large as Europe and Australia combined,centered roughly on the South Pole and surrounded by the most unobstructed water areas of the world -- the Atlantic,Pacific,and Indian Oceans.
这个 centered on 是以.为中心,这个centered on 相当于动词吗?难道这句话是说,南极洲是以南极为中心,并且被水流包围 areas of the world 在句子中又是作为什么成分?翻到这里真的翻不下去.
