【正确答案】 B

【答案解析】 [听力原文]
   W: Professor Mandy hinted that she wasn't that keen on students using Internet sources in their paper and seemed disappointed so many had.
   M: I'm just wondering if she'll take it out on me, especially. I used practically nothing else in mine.
   Q: What does the man imply?
由女士提到Mandy教授对如此多的学生“using the Internet sources in their papers”感到失望可知，Mandy教授反对学生利用网络资源写论文。由男士提到“I used practically nothing else in mine”可知，他只用了网络资源写论文，所以他很可能因此论文成绩不好，故选B。
