Attention please, everyone. We accepted the weather forecast on the radio this morning that there will have a heavy rain tonight. Be sure shut the windows and doors until you leave your classrooms. The winter sports meet that we planned to hold on tomorrow will be put off. After it bees fine, we'll make other announcement. We will have classes on Thursday as usually.
