题目
题型:不详难度:来源:
_______ from other continents for millions of years, Australia has many plants and animals not found in any other country in the world.
A.Being separatedB.Having separated
C.Having been separatedD.To be separated

答案
C
解析

试题分析:通过分析句子结构,这里需要用现在分词作原因状语,现在分词的动作发生在谓语动作之前,故用现在分词的完成时;并且现在分词的逻辑主语“Australia”与分词动作“separate”之间是被动关系,故用现在分词的完成时的被动式。
点评:非谓语动词是英语中的重点语法项目之一,它涉及词法、句法、时态、语态和各种习惯用法,易混点比较多,在句中的位置灵活,且句法功能较多。所以学习非谓语动词时应理清非谓语动词在句中所作的成分及它们之间的区别。
