The last decade of the 21st century ________ the rapid, steady development of China in various fields.
A.witnessedB.was witnessedC.is witnessedD.had witnessed
A

试题分析:考查时态语态:句意是:21世纪的最后十年见证中国在各个领域的快速稳定的发展。时间隐含在上下文之间,就是21世纪的最后十年,用过去时,也是主动。选A。
点评:时态的考查要放在上下文中进行,要抓住句子的关键词,这题的关键词就是The last decade of the 21st century,还要注意被动语态。
