1, carefully examine the questions and understand the meaning.

The first key to examining questions is to concentrate basic knowledge such as concepts, formulas and theorems. All the concepts, formulas, properties and other contents that appear in the questions are the key points of understanding, remembering and using at ordinary times, and are also the first objects that we need to recall when solving multiple-choice questions.

The second key to the examination of the topic is to discover the "organs" in the subject matter and some hidden conditions in the topic, which are often the "value" of the topic and the "hidden danger" for us to lose points.

2, repeatedly analyze the problem, to eliminate the false and retain the true.

Analysis topic means the purpose of analysis topic. On the basis of careful examination, the whole problem is repeatedly analyzed and dissected, so as to find the correct path to solve the problem. Therefore, the process of analyzing problems is the process of connecting knowledge and forming ideas according to the meaning of problems.

Because multiple-choice questions have similar and related characteristics, sometimes they are "true and false, and also true and false". For some specious options, we can compare them one by one with the types of questions, and analyze and verify them with some "imaginary" ifs to improve the correct rate of solving problems.

3, grasp the key points, comprehensive analysis

In the process of solving problems, it is very important to find the key points of the problem through examination and analysis. Starting from the key points, finding the breakthrough point, making a comprehensive analysis with knowledge, and forming the correct thinking of solving the problem can turn the difficult into the easy, simplify the complex into the simple, and work out the correct answer.

4, repeated inspection, check carefully.

Errors such as "increasing roots" are often caused by incomplete thinking in the process of examining and dividing questions. Careful examination is also one of the essential steps to solve multiple-choice questions.
