参考词汇：垃圾分类 trash sorting
Having learned that you are interested in the trash-sorting program promoted recently in China, I am here writing to give you a brief introduction.
As far as I know, Shanghai has become the pioneer of our country's waste sorting policy. As of July 1st this year, the residents in Shanghai have not been able to dump their waste bags in whichever bin was closest. On the contrary, domestic waste is required to be classified into four categories: dry refuse, wet trash, recyclable waste and hazardous(dangerous) waste.
Faced with the new rule, many citizens in Shanghaiare finding it a little too complicated, with every item of waste now under careful scrutiny(examination) and classification. Still, there are more people who warmly support the policy because it helps people to cultivate greener lifestyle habits and helps China to become a more beautiful country.

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.
