Dear schoolmates,
亲爱的同学们，
Over the past fifteen days, the novel virus has made its way around China. It has a strong impact on our life and study. Faced with the crisis, we students should respond actively to the appeal from authority and experts. In order to ease the serious condition, all of students had better do as follows.
在过去的15天里，这种新型病毒已经在中国传播开来。它对我们的生活和学习有很大的影响。面对危机，我们学生应该积极回应权威和专家的呼吁。为了缓解这种严重的情况，所有的学生最好做以下事情。
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.
首先，呆在家里，没有必要的话不要出去。对自己和他人负责。另外，在户外时一定要戴口罩。众所周知，它可以降低感染病毒的风险。也需要尽可能经常洗手。最重要的是，每个人都应该对疾病防治运动持积极态度。态度就是一切。
My dear friends, there may be a long way to go for us. Let's work hand in hand to overcome anxiety and do some bits. We have faith in the fact that tomorrow is another day.
亲爱的朋友们，我们还有很长的路要走。让我们携手合作，克服焦虑，做点事情。我们相信明天是新的一天。
