_____ from other continents for millions of year, Australia has many plants and animals not found in any other country in the world.

B
解析试题分析：考查现在分词的完成式：句意：被和其他大陆分开上百万年后，澳大利亚有很多植物和动物在其他洲是找不到的。逗号后面的部分是主句，前面这一部分只能是状语．作状语的非谓语动词逻辑上的主语应是主句的主语，即Australia．“分割开”这个动作发生在很久以前而且与其逻辑主语是被动关系，这样就需要用分词的完成被动式，故B对．
