题型:不详难度:来源:
A scientific report has found that snow and ice on Africa’s highest mountain Kilimanjaro ______rapidly and could vanish within 20 years.   
A.has been meltedB.will melt
C.is meltingD.was being melted

答案
C
解析

试题分析:句意:一份科学报告表明:非洲最高的山脉乞力马扎罗山上的积雪和冰层正在快速融化,并可能在未来20年内彻底消失。表示现在正在进行的动作,故用现在进行时。
点评:这种用法往往表示发生在过去,说话时没完成,仍在继续进行的动作或状态。做题时可以从上下文推断应选用的时态。主句用了现在完成时,从句中不会用过去进行时,从句中后半句中用了将来时,那么前半句就应该比将来时早一步,即“现在”,选项中A是现在完成时,C是现在进行时,根据主语和动词的关系可以排除A。
