First of all, you should learn to teach a teaching content (such as a preliminary understanding), including introducing topics, classroom teaching, classroom exercises, classroom summary and so on. You can refer to the relevant teaching plan, but pay attention to the fact that the interview is not a real class, so we will give you ten minutes, mainly to test whether you can teach the relevant teaching content and knowledge to the students and whether you can grasp the important and difficult points of teaching. The content of the trial lecture is usually taken out by the interviewer on the spot, which will give you time to prepare.
