Stories and jokes about the sun and shadows.

September 1st is the first day of school in autumn. Yang Yang is in Grade Five this year. The classroom in their class has also moved from the second floor to the third floor. Yang Yang stood alone on the third floor and looked down. Xiao Doudou, a first-year student, is frolicking on the playground. He experienced the feeling of condescending and going up a storey still higher, and felt that he had grown up at once!

Today, the homework assigned by the science teacher is to preview the lesson "Sun and Shadow" and collect information about the sun on the Internet.

At the sight of the topic "sun and shadow", Yangyang could not help but blurt out:

The sun shines in the sky,

Flowers smile at me,

The bird says, good morning, good morning, good morning. ...

The sun, the sun,

Bring us seven colors of brilliance. ......

Seven colors, seven colors, the color of the sun. ......

The songs I was familiar with when I was a child flashed through Yang Yang's mind one after another.

Yang Yang especially likes science classes and doing experiments. Every time he has a science class, he is very excited. Every time we have a science class, when the class is over, the science teacher will talk to the students for a while about the immortals who have lived for 5,000 years, ancient and modern, Chinese and foreign, in the sky and underground. When the bell rang, everyone still didn't want to leave the lab.
