1. In the mathematics test questions of the college entrance examination, the multiple-choice questions focus on the small synthesis of multiple knowledge points, infiltrating various mathematical thinking methods, and embodying the orientation of paying attention to examining the "three basics". Can you get high marks in multiple-choice questions? It has a great influence on the math scores of the college entrance examination. The basic requirements for answering multiple-choice questions are four words-accurate and fast. 2. Multiple-choice questions mainly examine the understanding of basic knowledge, the proficiency of basic skills, the accuracy of basic calculations, the application of basic methods, the rigor of considering problems, and the speed of solving problems. The basic strategy of answering multiple-choice questions is to make full use of the information provided by the topic and the choice of branches to make judgments. Generally speaking, if you can make a qualitative judgment, you won't use complicated quantitative calculation; If we can use special numerical values to judge, we don't need to use conventional solutions; If you can use indirect solutions, you don't have to use direct solutions; We should eliminate obvious negative choices as soon as possible and narrow the scope of choices; For those who have many ways to solve problems, they should choose the simplest solution. When solving problems, we should carefully examine the questions, analyze them in depth, deduce them correctly, and beware of omissions; Check carefully after the primary election to ensure accuracy. 3. The common methods to solve multiple-choice questions in mathematics are mainly divided into direct method and indirect method. Direct method is the most basic and commonly used method to solve multiple-choice questions. However, the college entrance examination has a large number of questions. If all multiple-choice questions are answered directly, not only time is not allowed, but even some questions can't be answered at all. Therefore, we should master some special methods to answer multiple-choice questions. Methods and skills 1, direct method: directly from the conditions of setting the problem, using related concepts, properties, theorems, rules and formulas, through strict reasoning and accurate operation, the correct conclusion is drawn. Then make corresponding choices according to the choice branch given by the topic. Direct method is often used for problems involving concept and property analysis or simple operation. 2. Special case method: replace the general conditions of the topic with special values (special numbers, special positions), draw special conclusions, and test each option. So as to make a correct judgment. Commonly used special cases include special numerical values, special series, special functions, special graphs, special angles, special positions and so on. 3. Screening method: Starting from the conditions of the topic, using theorems, properties and formulas to deduce, and according to the instruction of "choose one from four", gradually eliminate the interference items, so as to get the correct judgment. 4. Substitution method: substitute each option into the topic one by one for inspection. Therefore, a correct judgment can be obtained. That is to say, taking each branch as a condition to verify the proposition, the branch that can make the proposition stand is the answer to be selected. 5. Illustration: Make the curve or related figure of the learned problem according to the conditions of the topic, and make a correct judgment with the help of the intuition of geometric figures. Also known as the combination of numbers and shapes. 6. Cut-and-fill method is a common method to solve geometric problems, and it is skillfully used. Irregular graphics can be transformed into regular graphics, which can simplify problems and shorten the length of solving problems. 7. Limit method: from finite to infinite, from approximation to accuracy, from quantitative change to qualitative change. Using extreme thinking to solve some problems can avoid abstract and complicated operations, reduce the difficulty of solving problems and optimize the process of solving problems. 8. The valuation method provides the only correct choice, and the solution does not need a process. So you can guess and reason reasonably.
