Ask for a composition, the theme is a math evening study, suddenly the power went out, I am very happy, the teacher asked a classmate to sing without makeup, finished writing, the phone came.

The evening self-study began, the classroom was quiet, and the students were doing their homework seriously. Suddenly the power went out and the classroom began to get messy.

"Ah-"A girl screamed with fear, and someone took the opportunity to shout, "Help!" The originally quiet classroom suddenly became a mess. Yang Yang, a naughty little troublemaker, thought it was funny. He pushed down the desk and chair and laughed beside him. I don't know who moved the army chair again. In the dark, he sat on the ground and the classroom became more noisy.

"Everybody calm down, don't panic, it's just a power outage, nothing, let's recite ancient poems first!"

After listening to the teacher, the dark classroom quieted down a little, and the class representative appointed by the teacher led everyone to recite ancient poems together. However, I haven't made a phone call after reading the ancient poem. The teacher told us a joke: "A, B and C went shopping and saw a shop doing IQ tests, so they went in. At present, there is a computer connected to the headgear, and A sits on it, which is140; B sit up, it's 86; C sat on it, very nervous ... At this moment, the computer said, "Don't make fun of stones ... hahaha!" " "The students laughed and forgot about the power outage.

We have been listening to jokes and reciting ancient poems. Soon, the electricity will come! The students cheered and helped to tidy up the tables and chairs. The teacher looked around the classroom and said, "Let's do our homework quickly!" " "

The classroom is calm again, and even a needle can be heard.
