In the last decade, Chicago public schools ________ teaching of Chinese to serve 12,000 students.
A.are expanding B.have expandedC.expandedD.expand
题型:单选题难度:中档来源:不详

答案

B

试题分析:考查时态:如果时间状语是:in/during the last/past few +名词,谓语应该是现在完成时,句意:在过去的十年中,芝加哥公共学校一直在扩大汉语教学为12000名学生服务。选B。
点评:考查时态时,如果有时间状语,就充分利用时间状语,如果没有,要结合上下文找出来。时间状语是in/during the last/past few一定是现在完成时。
