In the answers to historical questions, there are many investigations on essence, essence and essence. Multiple-choice questions, material questions and question-and-answer questions are all included in different degrees, especially in the senior high school entrance examination papers. In order to help students correctly grasp the nature, essence and essential differences of historical evaluation terms when answering historical questions, this paper makes some brief explanations, hoping to help students.

Essence: refers to the fundamental attribute of things that determine the essence and development of things. The essence is often hidden and should be analyzed through phenomena. For example: summary; The power relationship of the allies in Versailles-Washington system, try to analyze the essence of this system. In the analysis, we know that the relationship between power mainly has two aspects; One is to divide the spoils, dominate and compete with each other; The second is collusion for common interests. The essence of this system is that imperialism redraws the world. This requires us to have a comprehensive grasp of its essence, content and influence when answering questions, to have a well-founded theory, and to give a concise historical answer.

Essence: the essence lies in the phenomenon, and it is expressed through the phenomenon. Our task in analyzing historical events is to understand the essence of things through historical phenomena, understand the connotation and extension of things' development, and accurately grasp historical concepts. For example, comparing the three historical concepts of "British bourgeoisie", "North American War of Independence" and "French bourgeois revolution", they are all bourgeois revolutions in essence, which have established bourgeois rule and promoted the development of productive forces. But the essential characteristics of the three are also different: in the British bourgeois revolution, it was compromised and the revolution was incomplete; The North American War of Independence was not only a war for national independence, but also a bourgeois revolution. In the French bourgeois revolution, because the bourgeoisie and the masses formed an alliance, the masses played a decisive role in the revolutionary struggle, making this revolution the biggest and most thorough revolution in the bourgeois revolutionary era.

When we answer questions about nature, essence and essence, we should compare them according to their different characteristics, and play the role of relevant knowledge points on the basis of a large number of historical concepts, which will naturally improve our problem-solving ability.
