An average of 130000 Chinese _________ abroad for studies every year over the past few years, boosting exchanges in the educational fields
A.was goingB.have been going
C.has been goingD.are going
B

试题分析:考查动词的时态。根据本句中的时间状语every year over the past few years“在过去的几年中,每年”可知,要用现在完成时态。现在完成进行时,现在完成进行时表示动作的持续性和延续性。同时前面的主语是130000 Chinese可知,用复数。句意:在过去几年中,每年平均有130,000人出国留学,促进教育领域的交流。
点评:动词的时态要注意句中的时间状语。本句中时间状语是every year over the past few years。
