Question

In recent years, the economy of our country ________ rapidly.

A. is increasing    B. have increased

C. increased    D. has increased

Answer

D

【解析】

句意：近些年来，我们国家的经济飞速发展。is increasing现在进行时，正在提高；have increased现在完成时；increased过去式；has increased现在完成时，主语为单数。句中的in recent years 意为“近些年来”，是现在完成时的时间状语，又主语the economy of our country是第三人称单数，故选D。
