To whom it may concern,
I am Li Hua, a senior school student. I am extremely sorry to disturb you, but I have to write a letter to convey my complaint and dissatisfaction.The novel coronavirus epidemic is still tough and annoying. However, you can't imagine that a small number of businesses are so mean as to sell the face masks at an unreasonable price. It is said that it can be five times as high as the normal price. My classmates and I are burning with anger.I hope Consumers' Association can give much attention to this. I'd appreciate it if you can cope with it as early as you can.
假定你是学生会主席李华，当前新冠状病毒肆虐，请你围绕 “从小事做起共战疫情” 这一主题，给全校学生写一封英文倡议书。

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.
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 some bits. We have faith in the fact that tomorrow is another day.

Since the outbreak of novel coronavirus pneumonia in Wuhan in December,2019,I have been staying at home.On the one hand,I pay close attention to the epidemic situation through watching CCTV news or surfing the Internet;on the other hand I insist on studying.Not only do I read classics, but also I have online courses given by my teachers.Besides,I take exercise every day to keep healthy.Faced with the disaster,many people including doctors,nurses and scientists act bravely and spare no effort to fight against it.They are real heroes.
Thank you for your concern.I’m looking forward to your reply.
