"Only One Earth"

This text mainly tells us: We only have one earth, and we must protect our earth. Around this central text, we talked about the color and shape of the earth, the limited resources of the earth, the inability to colonize other planets, and the need to protect the earth. I plan to review three ancient poems first, then explain the words, and then ask the students to read through the text and find out what the article is about. What aspects have been written about this content article? Finally, it leads us to protect our earth and the ecological environment of the earth.

When Teacher Du was talking about this article, after talking about the words, he first analyzed the title and said that it was a resounding slogan put forward by the Human Environment Conference held in Stockholm, the capital of Sweden, in 1972. I didn't notice this before. I just thought the title was a clue to the article, but I ignored it. When talking about the content of the text, Teacher Du said this: read the text silently, and use the key sentences to talk about the content of the text. And the methods are given: 1. Circle key sentences to summarize the content of the paragraph; 2. Merge relevant paragraphs to grasp the content of the text; 3. Use outlines and notes to organize. Provide very clear method guidance to students.

While listening to Teacher Du’s lecture, I discovered a very big problem: I usually ask students to search in articles during class, and they can all find it, but there is a problem: for example The answer is one sentence, but the students will read out several sentences near it. The answer is not particularly accurate, and they say that they are looking for it correctly. If they are not looking for it accurately, they will say that they are looking for it incorrectly, and there is nothing they can find. Wrong, I have never known how to answer this question. Today, Teacher Du told me that I should do this: In this text, there is a paragraph with only one sentence: "Some people will say, isn't the universe very big? There are countless "Planet, when the earth's resources are exhausted, can't we move to other planets?" This natural paragraph only has this sentence, so when looking for the key points, can we draw this paragraph? Teacher Du said, students, think about it, what does this natural paragraph say? This natural section raises the question of whether we can move to other planets? According to this question, can we circle that we cannot move to other planets? When we encounter a one-sentence paragraph, we should also read it carefully, find out the key points of the paragraph, and circle it.

This lesson has three topics. They are what aspects are covered in the text, how we came to the conclusion that we need to protect the earth step by step, and several pieces of publicity against environmental damage. slogan. When I was reading, I always felt that there was not much difference between the first two after-school questions. When I read the complete solution of the textbook, I was also vague about the answers to these two questions. I felt that the two seemed to be similar. But after watching Teacher Du’s class, I found that there are big differences between them. When solving the first problem, Teacher Du asked the students to find the central sentence in the article to summarize each paragraph. When asking the second question, we begin to conduct a detailed analysis of the article. In other words, the first question is equivalent to the overall perception of the text. For the second question, we have to lead the students to conduct a detailed analysis of each paragraph. The first part of the article is from the perspective of an astronaut. The second part talks about the lack of natural resources on the earth and what the earth and humans have done to each other. The third part writes that we cannot go to other planets in one sentence. This step by step It inspires human beings' emotions to protect the earth, explains it step by step, and finally leads to the conclusion that we must protect our only earth.
