The so-called "water lessons" are those that are of little value to you and waste time. To put it bluntly, this kind of course is very watery and has no practical and practical significance, but it also restricts your credits. At school, I believe that each of us has encountered such a "water class" once or twice, and most people take "skipping class" as a coping strategy, and I am no exception.

As an ordinary second-rate university in Wuhan, I have encountered many such courses from freshman to senior. Without exception, their characteristic is that teachers are bored and watching PPT all day is of little practical significance. I remember when I was a freshman, we had a class called, the name sounded good, but I didn't know how much water there was until I got there. ......

Our "teacher" is not the so-called "teacher" at all, but is found by the school from outside. The lecture is to watch PPT and keep watching it. What is more exaggerated is that the "teacher" in the first class didn't know how to use PPT, and then we helped her open it and told her how to use it ... Now I feel drunk, but we shouldn't be unlucky enough to meet such a "water" course and teacher.
