First, we should take this as the foundation and lay a solid foundation. As a form of senior high school entrance examination proposition, the main purpose of open-book examination is to reduce students' learning burden, encourage students to express their opinions, cultivate students' innovative consciousness and creative thinking ability, and present a flexible, open and comprehensive turning point. Faced with such characteristics, students are required to master basic knowledge, remember and understand the meaning of basic concepts and principles, repeat the general idea, and make full preparations for preparing for the exam. Second, based on the foundation, pay attention to ability training. This requires us to master the basic knowledge, break through the limitations of various courses in the textbook, sort out the knowledge (vertically and horizontally), summarize and compare the similar knowledge, so as to grasp the inner things, and we can't mistakenly think that the open-book exam is just copying books without spending more time. As long as you can do more work, think more and accumulate more in review, you won't be in a hurry when you come to the exam. Third, pay attention to current events. Applying what you have learned and solving practical problems is not only a requirement for improving your ability, but also a headache for students. This requires us to consciously pay attention to social hotspots, such as the same problems (nuclear weapons, SARS virus), hegemonism and power politics, terrorist activities and so on. Be a conscientious person, accumulate more and help solve problems. Fourth, we should master some review methods. (1) bookmark method. The history exam has a wide range, many knowledge points and is scattered. In order to facilitate the search, you can put a small bookmark on the textbook and sort out and classify the knowledge points at the top or left of the textbook step by step. (2) Correctly handle teaching materials and materials. In the current market, there are various review materials, so it is necessary to correctly select representative review materials. This material should include reviewing the basics, explaining the important and difficult points, guiding the problem-solving of various types of questions, and summarizing and sorting out the knowledge points. , purposefully self-test. For questions that can't be completed independently or can't be answered at the moment, find classmates or teachers to solve doubts, instead of waiting for answers and learning passively. ⑶ Be able to arrange the review time reasonably. You can spare some time every day to review and consolidate what you have learned, or you can intersperse it in the process of science review or use the weekend to review and consolidate it in stages. Don't get cold feet. (4) Master the correct answer method. It is necessary to feed back the effective information such as the conditions, time, place and direction given by the topic to the textbook, so as to examine the topic clearly, understand the stem of the topic and find the breakthrough point. Multiple choice questions can adopt exclusion method and standing legislation. Material questions should make full use of the information provided by materials, screen, sort out, analyze and answer questions. Questions and answers generally have a time range, which needs careful investigation. At the same time, we should find out the dry part of questions and answers, and pay attention to the order of answers.
