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. The sports meet that we planned to hold on

tomorrow will be put off. After it becomes fine, we’ll make other announcement.

We will have classes on Wednesday as usually. Since it is colder tomorrow ,please

dress on more clothes in time. Those who comes to school by bike ,don’t keep your

umbrella open while riding.
