A.couldn't have takenB.should have taken
C.needn't have takenD.must have taken
在线课程【答案】B
【解析】
考查情态动词+have done结构。句意：我对我的高中时光有一个遗憾：我本应该上一些在大学里很有用的高级课程。A. couldn't have done不可能做过；B. should have done本应该做而没有做；C. needn't have done本不必做却做了；D. must have done一定做过。根据“1 have one regret”可知此处表示“本应该做而没有做，所以才有遗憾”，故B项正确。
