Question

－Hi, Nancy, I didn't know you had come back．So have you graduated from college?

－Yes．I ________ French for four years in Nanjing．

[　　]

A．have studied

B．had studied

C．studied

D．am studying

Answer 1

答案：C
解析：

难。考查时态。根据上句所说已经毕业，那么在南京读书就是过去的事，因此可排除have studied和am studying，过去完成时表示的是过去的过去，显然不对，因此只能选择一般过去时。
