Attention please, everyone. We have 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. A
sports meet that we planned to hold on tomorrow will be put off. After it becomes fine, we will make other
announcement. They will have classes on Wednesday as usual. Since it is colder tomorrow, please dress on
more clothes in time. Those who came to school by bike, don't keep your umbrella open while riding.
