B. Write a complaint letter to the head of your school to tell about using electricity in your class.
In your class, many students use the electricity for lighting. What makes you worried about that is they use the electricity wastingly. When they go to class , they turn on the lights everytime, they don’t care about the classrom light or dark. Besides , they switch the fans on although the weather is very cold. They don’t turn off the fans and the lights after using and noone use them. They sometimes forget to turn off all devices in class after schhool, so it waste the electricity too much. You thinhk that the principal ought to ask these students to turn off all the electric devices in all classrooms if not necessary and punish any classes not obey it.
