Joseph to evening classes since last month, but he still can’t say “What’s your name?” in Russian.
A. has been going
B. went
C. goes
D. has gone

(答案→)A. has been goingB. wentC. goesD. has gone解析：考查动词时态。根据句中的时间状语since last month可排除B项和C项；现在完成时表示到现在为止已经完成或过去发生但强调对现在的影响的事情，现在完成进行时表示到现在为止一直在做某事，强调连续性。句意：约瑟夫自从上个月以来一直在上夜校，但他仍然还不会用俄语说“你叫什么名字？”。故选A项。

回答的不错
