____________ from other continents for millions of years,Australia has many plants and animals not found in any other country in the world.
A Being separated B Having separated C Having been separated D To be separated
C
考查非謂語動詞作狀語。短語be separated from 與什么分開，Australia與separate之間是被動關(guān)系，且分詞的動作發(fā)生在謂語動詞之前，故用現(xiàn)在分詞的完成式。所以選C。
