The purpose of using the song Bunny is to let students learn to listen and think with their ears, so as to run through the whole classroom teaching and guide students to become smart children with "ears, eyes, mouth and heart" and pave the way for the next link. )

Second, contact life, clear picture and meaning.

(1) Introduce topics and show pictures. The rabbit is very clever. It won't open the door when it knows it's the wolf. Today, a child met a situation similar to that of a rabbit. what should he do ？ (Board Question: What should I do? Raise your right hand and write together!

Health: One day, Xiaoming's parents went to work, and Xiaoming was doing his homework at home alone. Suddenly I heard a knock at the door.

(3) Who will connect these four pictures? Let's take a look at Xiaoming's problems. Xiaoming has a problem, shall we help him solve it together? Health: OK. Teacher: What a group of helpful children. (Design intention: The content of this oral communication is quite close to students' real life. This process is mainly to guide students to learn to observe one thing in order and make it clear. On the basis of making it clear, try to be as detailed as possible and show the pictures vividly in the text, so that students can observe the pictures carefully, think hard and tell what the pictures are. Make the story clear, and pay attention to complete the sentences in the process of speaking.

How come? Talk about it in your own life. How do you receive guests politely? How do you treat strangers? How to protect yourself? Let two students perform different scenes with the teacher at the scene, and the teacher evaluates them. Make way: warm reception

(2) Don't let me in: Explain the reason clearly and put it mildly. If uncle insists on coming in, he should be tactful. Teacher: Because of the time, we can't perform any more. We can also perform with our parents and see what they can do.
