The teacher opened the door and went out with a creak. Suddenly a pot exploded in the classroom, and Zhang Hui stood on the chair and shouted, "Wow, the teacher is gone! The teacher is gone! " Wang Ming got down from his seat and rushed to Li Jun's desk. He talked with him excitedly, and Zhou Wei didn't want to be alone. He waved the card and shouted, "Change the card!" Chen Xiaoyu is like a bird, twittering, beaming and talking nonstop. Paper frogs began to take part in the long jump competition on many desks. They chased each other, not to be outdone. The contestants cheered one after another. The female students opened their eyes, shook their long braids, whispered and talked to each other. The classroom has become a messy hornet's nest.

At this time, I don't know who said: the teacher is coming. The classroom suddenly became quiet. After a while, this group of people saw that Teacher Lu had not come yet and began to shout again. Zhang Hui ran around like a mouse, and Li Jun ran around like a mummy. Wang Ming simply jumped on the table with a paper plane in his hand, and the paper plane flew up and down with a bang. The glass filaments in the hands of female students turned into buds and ribbons. ...

Suddenly, the door opened and the teacher came into the classroom lightly. Zhang hui is one leng, at a loss. Suddenly, as soon as his eyes turned, the cat was tied around his waist like a wisp of smoke, and he slipped back to his seat in fear. Wang Ming was so scared that he fell off the table. He rubbed his sore ass and stole a glance at Teacher Lu. Alas, the paper plane broke into pieces in Lao Lu's hand, and the paper frogs of the racers immediately disappeared without a trace ... The classroom was silent, and even an embroidery needle could be heard falling.

This is our classroom.
