How the Yellow River Changes".

This is a long but illustrative skimming text, which introduces the changes in the Yellow River, the reasons for the changes, and the plans that scientists have devised to control the Yellow River, so that people can understand that the destruction of forests is an out-and-out act of suicide; It is necessary to rationally plan and utilize land, and at the same time, it is also necessary to build a large number of water conservancy projects. We human beings should protect nature and care for the environment.

When teaching this lesson, I want students to read the text on their own to understand the content of the text, and then ask questions for them to answer by themselves. 1. What was the Yellow River like? 2. What happened to the Yellow River?

3. What are the reasons for the change of the Yellow River? Natural factors: the temperature turns cold, the rainstorm is concentrated, and the loess is loose, resulting in soil erosion.

Human factors: rapid population growth, unlimited reclamation and grazing, destruction of green vegetation, loss of natural protection, soil erosion.

Students can easily find the answers to the above questions from the text. However, many problems have also been exposed in the course of the problem. The students' texts are just not very stockpiled, and some natural knowledge is not understood.

For example, the term "hanging river" is not implemented properly, and students do not understand such a geographical concept. On this issue, I drew a diagram of the Hanging River on the blackboard for the students to see, so that it would not be difficult for the students to understand the disaster caused by the Hanging River when they read the text.

After solving the above problems, guide students to conduct in-depth research, what kind of plan have scientists designed to control the Yellow River? What are the lessons of the changes in the Yellow River? What inspired you to study this text?

Through a series of questions and answers, students learn about the changes in the Yellow River.

After class, I felt that the students' knowledge of the texts was insufficient, due to the limitations of the teaching conditions in rural schools, the students could not show the broadening materials in the classroom, and some useful knowledge could not be accumulated, and their abilities were limited, which led to obstacles to understanding the texts. For each extracurricular knowledge related to this, I let the children use the computer to check the relevant information every other time.
