1, prepare for class, that is to say, preview before class, find out what you don't understand, find problems, and go to class with knowledge points and questions, which will be more enjoyable and easier to listen to and master;

2. Participate in communication and interaction. Don't just put yourself on the sidelines of "listening", but the participants of "listening". Think positively about the questions the teacher said or asked, and answer them when you can (the benefits of answering questions are not only performance, but also make you more focused).
