I know you should be a middle school student. I can explain it to you and see if you can understand it. We can regard geography as a spatial dimension and history as a time dimension. Space and time are two coordinates that keep us alive. For example, you were in Beijing today and you were in Shijiazhuang yesterday. The geographical space contained in it is two spatial points, Beijing and Shijiazhuang, today and yesterday. If there are enough places, a geospatial grid will be formed, and if the time is long enough, it will become a long river of history.
I can talk about this problem from another aspect. For example, China and the United States are two countries with different geographical locations; And we also know that the United States is a developed country and China is a developing country. You should have heard the saying that China has lagged behind the United States for many years, which can be said to be the time difference between the two countries. In other words, China and the United States are in different geographical spaces and at different stages of development. In the process of development, China should not only learn from the development of the United States today, but also learn from the history of the United States. China's reference to the United States is a combination of space and time, and a combination of geography and history.
Of course, it is unreasonable for geography and history to be taught by the same teacher. It may be because the teachers in your school are not enough for the time being. Please wait patiently for the time being.
