Case background "There are many interesting things in space life" is a text in Unit 8, Book 3, a new Chinese textbook for primary schools published by People's Education Press. In the first seven units, there are beautiful articles, catchy poems, fables full of childlike interest and poems with simple artistic conception. Let teachers and students enjoy the richness and profundity of language and writing. Suddenly entering the eighth unit, there are two difficulties: first, the ideological realm has improved. The purpose of teaching is to cultivate students' interest in science while understanding the language, and to establish the lofty goal of loving and learning science from an early age and making contributions to the motherland when they grow up. Second, each textbook has a long length, plain language and many long sentences. It may be a mistake to feel the artistic conception of words and taste the wording and sentences of articles in some usual ways. Therefore, this text must take advantage of the situation, grasp the word "fun" to open the entrance on the basis of basic understanding of the text content, and let students carry out inquiry learning inside and outside the classroom. Teaching record students read the text first and read the article smoothly. Read the text again to understand the meaning. Teacher: Students, after reading the content just now, can you tell us your feelings? Health: Life in space is so interesting! Teacher: How interesting? Why is this happening? Students retell the text in their own words and explain the reasons. Health: I want to ask astronauts how to wash their faces and brush their teeth. How do astronauts watch TV? How do astronauts go to the toilet? (Some students laugh) (The first step of inquiry: ask questions. ) Teacher: These questions are very interesting. Can anyone answer this question?
