Recommend a wave of very practical websites to everyone. First, the subject network, where there are a lot of learning materials to look up, is very practical for me as a junior high school student. When I have nothing to do, I can find some exercises to do in all subjects. The second is the ancient poetry network, which is especially useful for students who love ancient poetry. The poems in it are super comprehensive, and there are analysis notes to check, which is very helpful for understanding poetry. The third is interesting history, which is very suitable for students who love history. All historical events have been completed. The fourth is the Senior Three Network, which is recommended to senior three students. There are many real questions in the college entrance examination in various provinces and regions over the years, as well as simulation questions, which can be used for review. These websites are very practical. Of course, students also need to listen carefully in class. Together with these websites, learning efficiency can be improved.
