请教一道PP听力题

PP听力有一个对话是说：

W: I really hate walking into class late, at least the professor didn't seem to notice it.
M: I am not so sure about it. She sound a kind of angry to me.

a: The woman may have upset the professor
d: The professor didn't notice the woman was late.

答案选：A，我选D，不明白，请教啊～！

选A，那个Man的意思是他觉得教授有些生气。 我记得我问过几个人，好像是这么说的。哈哈

是的。

女生说：我讨厌迟到，可是至少老师不太注意（迟到的现象）。

男生说：我可不敢肯定（是这样），听起来她对我（迟到）可有点恼火。
