参考答案

正确答案：D
解析：[听力原文]
W: Are you going to graduate next year?
M: Maybe not. I don't have enough credits in my major yet and I still have some basic courses to take.
Q: Why can't the man graduate next year?
根据选项可知问题询问原因，并且和He的学习有关。女士问男士准备明年毕业吗。男士说可能不行。他没修够专业学分，仍要上几门基础课程。从“don't have enough credits”可知他仍需要更多学分。故正确答案为D)。
