China sent up Shenzhou V manned spaceship into space successfully, which shows  science and technology ___ rapidly in China.
A.have been developing B.developsC.is developingD.has developed
C

试题分析:science and technology是一个名词短语——科技,是一个整体,故谓语动词用单数,排除A,根据句意,是说现阶段中国的科技正快速发展,故使用现在进行时。
点评:考查时态。经常会和主谓一致的语法一起考查,因此可以根据主谓一致的原则用排除法先排除部分选项,再根据上下文语境选择正确时态。
