If you can't grasp the historical time, you can look at the chronology of major events behind the history books. There are horizontal and vertical timetables, so you can sort out the time.

The key to history is to establish a context. First, let's take a look at my textbook as a whole. For example, from the perspective of world history, we can establish the context of the development of capitalism, from the germination and initial development of capitalism (the opening of new routes, the colonial movement) and development (the feudal autocracy has formed a shackle on the development of capitalism, so the bourgeoisie demanded to clear the way for the development of capitalism, and the bourgeois revolution appeared in Britain, the United States and France. As well as the Renaissance, the Religious Reform and the Enlightenment to Emancipate the Mind), the first and second industrial revolutions were finally completed, which was also the result of certain development of capitalism: the workers' movement (socialist movement), the first and second world wars, the golden age of capitalist development after the second world war, regional collectivization and globalization.

With such a comb, the whole world history is very clear. On this basis, plus the time, background, cause (fundamental, main, fuse), process, result and influence of historical events, it can be said that we can master books well, and we can learn history well after some high-quality papers and homework exercises and in-depth thinking. This is a longitudinal comparison.

Horizontal comparison is necessary, which requires you to make a good comparison yourself. For example, when you study the industrial revolution in world history, you should link its completion time with the Opium War in China, the second industrial revolution with the Sino-Japanese War in the Sino-Japanese War of 1894- 1895, and learn to compare the world history with the history of China, so that you can understand and answer more easily.

Of course, on this basis, we must also establish Marxist historical materialism and dialectical thought: the economic base determines the superstructure, the productive forces determine the relations of production, and the relations of production must adapt to the development of productive forces. The answer that affects the meaning must be answered from both positive and negative aspects. We should grasp the main contradiction and look at the essence through historical phenomena. Only in this way can we grasp the direction of doing the problem and not lose our way. Many questions are based on this.
