2.细节理解题。由第四段中的"No one put up hands.’可知没看人完成了所有的五个问题。因此选择A项。

4.推理判断题。由教授所说的话可以知道他想教给学生们的道理。由 there are still many things about the subject you don’t know 和 your education just begins from now on 可知教授的意思是虽然学生们学完了大学的课程,但是对于这门课还有很多不知道的内容,学习才刚刚开始,故选C项,意为"活到老学到老"。
5.主旨大意题。文章最后一句" The years have obscured the name of this professor, but not the lesson he taught. " 强调了这节课很难忘,结合全文内容可知应选择C项(一节难忘的课)。
