The content of the test questions covers topics such as preparatory knowledge, function, geometry and algebra, probability and statistics, mathematical modeling activities, mathematical inquiry activities, etc., and realizes all-round coverage of basic knowledge. For example, the single choice of 1-5, the multiple choices of 9- 10, the filling in the blanks of 13- 14, and the solution of 17 are all to examine students' deep understanding and comprehensive application of basic knowledge and methods, and also to help students quickly enter the examination state.
In the process of making situational test questions, control the number of words when cutting materials and the difficulty of reading comprehension; When abstracting mathematical problems, set reasonable thinking intensity and abstraction degree; When solving problems, set appropriate calculation process and quantity, and strive to make situational test questions reach the required level of test questions and the cognitive level of candidates. For example, the topic 12 examines binomial distribution and its application in the background of signal transmission. This topic designs two transmission modes: single transmission and triple transmission, and studies the probability of obtaining correct signals for each transmission mode in turn, and investigates the ability to understand and explore new concepts and new knowledge. Another example is 19, which is based on the real problems in students' lives and close to students' reality, and has practical significance and research value. This problem needs to balance the missed diagnosis rate and misdiagnosis rate reasonably and establish the detection standard. The situation of the problem has both practical significance and mathematical application value.
