Read the poem I like long nights first.

(1) Teacher's Guide: A few days ago, all the teachers learned a nice poem with us. What's its name? How do you think this poem sounds?

(2) Children read poems in a warm and pleasant voice.

Second, the secret of the night.

(1) It's a long night. Do you know how the night comes?

(2) The teacher fixed the lighted flashlight at a certain distance from the globe, and pasted the red five-star of China on the globe. Let's look at an experiment. The globe represents the earth where we live, and the light of the flashlight represents the sunshine. When China is facing the light source, tell the children whether it is day or night in China.

(3) The autobiography of the teacher manipulating the globe. When China district deviates from the light source, please ask children to judge whether China is day or night.

(4) Teachers continue to turn the globe so that children can observe and judge the transition between day and night.

Third, the dialogue between day and night.

(1) Day and night. Day comes, night goes, night comes and day goes, so they will never touch each other. On this day, "Mr. Day" wanted to call "Miss Night" and listen to what they said.

(2) Teachers talk in the tone of "Mr. Day" and "Miss Night".

Mr. Daytime: I've never seen the night. Can you tell me how it is there? Miss Ye: Yes, yes, I haven't been to your place either. Can you tell me how it is there? )

(3) Ask the children to help Mr. Day and Miss Night answer what they are like there.

(4) Let the children play Mr. Day and Miss Night, and then ask each other questions.

And answer questions about day and night. You can exchange role-playing to play.
