How to make logical judgments and reasoning skillfully

Logical reasoning problem-solving skills Logical reasoning questions mainly examine candidates' logical reasoning ability. This type of question is to give a statement in each question, and the statement is assumed to be correct and unquestionable. Please choose a conclusion that can be directly deduced from the statement from the alternative answers according to the statement. Logical reasoning involves all fields of natural and social life. It emphasizes the correct grasp of logical relations and examines the thinking ability of candidates in understanding, analyzing, synthesizing, judging and reasoning all kinds of information. Although the topic is difficult, candidates should pay attention to that this part does not specifically examine logic and professional knowledge in various fields. It adheres to the principle of "treating all candidates equally" and only examines one basic logical thinking ability of candidates. Zhu Kao. Based on the examination experience over the years, the paper summarizes five principles of solving logical reasoning problems, hoping to help candidates improve their problem-solving skills. 1. This problem comes before the stem principle. Look at the question first, and then read the statement of the stem. Logical judgment questions can be divided into several categories according to different ways of asking questions. Therefore, before reading the stem, look at the questions first, judge what kind of questions they belong to, and then read the statement of the stem with questions, so that you can quickly clear your mind and find the correct answer. 2. Stick to the principle of answering questions. The topic statement part is the essence of the whole topic, so we should stick to the principle of answering questions and not add personal subjective assumptions at will. Because there is an inevitable connection between the premise and conclusion of logical judgment questions, the conclusion must not exceed the scope stipulated by the premise. Therefore, when answering questions, candidates must reason strictly according to the stated assumptions given in the questions. They should not ignore the facts stated in the topic because they feel that the stated assumptions are unreasonable or deviate from their existing knowledge and experience, and mix personal opinions and opinions at will, so it is easy to choose the wrong answer. 3. The main principle is the premise. When the options of the test questions are very confusing and each option seems reasonable, which makes it difficult for candidates to answer, candidates should adhere to the principle of "focusing on the premise of the topic". Just because the option seems reasonable does not mean that it is directly related to the premise statement given by the topic. The correct option should be deduced directly from the premise statement. When the discussion of an option is correct, but it cannot be directly deduced from a short statement, the option should be excluded. 4. The principle of simplifying. When we encounter complicated judgment and reasoning questions, we can visualize the content that needs reasoning by means of symbols, figures, tables and other forms, which can help candidates choose quickly and accurately. For example, draw a circle when doing a syllogism problem (that is, Euler diagram); You can draw a table or something when you do relational reasoning. 5. Clever use of methods and principles. According to the characteristics of the topic, we should make full use of the common methods to solve multiple-choice questions-exclusion method and substitution method. Because these two methods often don't need to finish reasoning, in many cases, three items have been excluded from the reasoning process, which saves a lot of time while helping candidates choose the correct answer. In addition, when logical judgment involves mathematical problems, we should broaden our thinking and dare to use mathematical methods (such as calculation) to solve problems. Don't think that logical judgment can't be solved by mathematical methods.
