选择题
—Have you been working in N0.5 Middle School since you graduated from college?
~No, I _______ in the countryside for 3 years.
A．have taught
B．had taught
C．have been teaching
D．taught
答案
答案：D
本题考查动词时态。由问句时态Have you been working可知说话时间是现在和现在在N0.5 Middle School工作；再由“No”可知“并非一直在N0.5 Middle School工作”， 结合这两者点可判断在此之前曾在农村工作了3年。所以选D。
