题目解析:
学生在说了Actually…that’s OK之后,马上又补充到不会占用多长时间(this won’t take very long)。由此可见,比起以后再来一趟,他希望即使谈得短一些,也要在现在说。因此正确答案是C。
【对应原文】
Professor: Well, I've got a meeting with the art department faculty at 10:00 so you'll have to make it brief...or you could always come back later. I'll be around for a while this afternoon.
Student: Actually...that's OK. I mean, I think this won't take very long.
