Attention, please.
It is six o’clock in the afternoon. I’m now giving the weather forecast as usual. From midnight to 2:00tomorrow there will be strong north wind blowing across our town. As a result, the temperature will drop by 5~8℃. Also there will be showers tomorrow morning. Therefore, be sure to close all the windows when you leave your classroom tonight. Besides, put on more clothes in order to protect yourself catching cold when you get up tomorrow morning.
That’s all. Thank you.
