Teachers with intermediate titles are not allowed to use teaching AIDS to prepare lessons during lectures. Do you want to force the teacher to death?

Can't stand it. Since it is a lecture defense, he certainly won't let you bring books. He should give you some hints. For example, you will be given two pages of textbooks when drawing lots. You can read the two-page textbook and give a lecture defense after you finish it. Secondly, examine your personal ability level and whether you can reach the standard of this title. Therefore, you can't use textbooks as teaching AIDS.
