【Possible version】
Dear schoolmates,
Over the past fifteen days, the novel virus has made its way around China. It has a strong impact on our life and study. Facing the hard time, we students should respond actively to the appeal from the government and experts. In order to ease the serious condition, all of the students had better do as follows.
First of all, stay at home and don't go out if not necessary. Be responsible for yourself and others. In addition, do wear masks while you are in the open air. As we all know, it can reduce the risk of contracting the virus. Washing hands as often as possible is needed, too. Most importantly, everyone ought to have a positive attitude to the campaign with the disease. Attitude is everything.
My dear friends, there may be a long way to go for us. Let's work hand in hand to overcome anxiety and do something about it. We have confidence in the fact that tomorrow is another day.
