I also clearly remember the first class of self-study every night. The English teacher played English listening on time at 6 o'clock every day and completed a set of listening questions. However, the hardware conditions of our time were not particularly good. Every time the teacher took the tape recorder to give us the hearing, but every time I did the problem, I would be depressed. I can’t understand what the hell is saying, the number of students in the class is much, the recorder Placed on the front podium, the students behind can't hear clearly, and every time they can't put their ears on the recorder to listen.
