Tell people that if they want to know things thoroughly, they must practice them themselves5

On paper, I finally feel shallow, and I never know that I have to do it.

A correct understanding often requires ......Only by the understanding of practice, from the understanding of practice and the repetition of practice can the answer be completed.

In the process of understanding, there is always a contradiction between subjectivity and objectivity, and people's understanding is limited by various conditions.

the knowledge level and thinking ability of the subject;

The object aspect includes changes in things, scientific and technological conditions, etc.

1) People can only gain knowledge of things in practical activities. (2) Just engaging in practical activities may not be able to recognize the nature and laws of things. In order to gain an understanding of the nature and laws of objective things, it is necessary to realize Qi Sen's leap from perceptual understanding to rational recognition.

3) To make the leap.

Practice is the only criterion for testing truth, so it is right.

(1) Practice is the basis of understanding. People can only gain knowledge of things in practical activities. Therefore, practice makes sense.

2) Just engaging in practical activities may not be able to understand the nature and laws of things. In order to gain an understanding of the nature and laws of objective things, it is necessary to make the leap from perceptual understanding to rational understanding.

3) To achieve this leap, people must possess rich and real perceptual materials through practice, and use scientific thinking methods to process and produce perceptual materials, so as to understand the essence and laws of things through the phenomena of things.

This question examines the knowledge of the relationship between practice and cognition, the relationship between perceptual cognition and rational cognition, and examines students' ability to think dialectically, judge the right and wrong opinions, and analyze and reason. First find out the points of this question: first, practice produces true knowledge; Second, by participating in practice, we will be able to understand the essence and laws of things.

Then analyze these two points separately, practice to find out that true knowledge is correct, and analyze the reasons for it; Participating in practice only provides perceptual material for understanding the essence and laws of things, which shows that the view that we can understand the essence and laws of things as long as we participate in practice is one-sided, and then answers how to raise the acquired perceptual understanding to rational understanding and understand the nature and laws of things. This question is carried out according to the general law of answering the discriminatory questions, which should be summarized in ordinary times, and this rule is: first look for the discernment points, which often have both the correct and the one-sided points, and then analyze these discernment points separately to find out the reasons.

1) People can only gain knowledge of things in practical activities.

2) Just engaging in practical activities may not be able to understand the nature and laws of things. In order to gain an understanding of the nature and laws of objective things, it is necessary to make a leap from perceptual understanding to rational understanding.

3) To achieve this leap, people must possess rich and real perceptual materials through practice, and use scientific thinking methods to process and produce perceptual materials, so as to understand the essence and laws of things through phenomena.

The knowledge points examined in this question are the relationship between practice and cognition, as well as the understanding of the nature and laws of things through phenomena, which is intended to test students' dialectical thinking ability and ability to flexibly apply the knowledge they have learned. The specific requirements for answering this type of analysis question are: first discernment, then analysis.

That is, first judge the reasonableness and unreasonableness of the viewpoint, and then analyze why it is reasonable and why it is unreasonable. In this question, we must first recognize the importance of practice, without practice, we must not be able to understand the essence and laws of things; Secondly, it should be clear that participating in practice does not necessarily mean that you will be able to understand the essence and laws of things. Finally, we will further trace the root cause and draw conclusions about how we can understand the nature and laws of things.
