疫情 epidemic situation
新型冠状病毒肺炎 COVID-19 (Corona Virus Disease 2019)Dear Leslie，
I'm glad to receive your email. You asked me to share with you what I'm doing in the epidemic situation. Here are my experiences.
Since the outbreak of COVID-19 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.

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 Shanghai are 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.

Dear Mrs. Zhang,
I'm writing to express my sincere gratitude to you. You gave me a hand when it was very necessary.
One month ago, with the College Entrance Examination around the corner, I was nervous and in low spirits. I was afraid of letting my parents down because of my average academic performance. When I was at the point of giving up, you asked me to go to your office. Instead of blaming me, you comforted me and discussed with me my reasons for failing the exam. You managed to help me with my studies and always inspired me. Gradually, I learned how to make my own adjustments. Thanks to you, I stayed calm during the College Entrance Examination.
Mrs. Zhang, I'm extremely grateful for what you have done for me. I will always have hope because of you. I wish you happiness and good health.

There are lots of places of interest in Beijing.
I'm glad to hear that you are interested in traditional Chinese festivals.
My favorite Chinese festival is the Spring Festival which comes on the first day of the Chinese Lunar Year.
In a word, it is high time for us to treasure and develop our own valuable culture.
In my opinion, some measures should be taken to protect traditional culture effectively.
假定你是李华，想邀请外教Henry一起参观中国剪纸 (paper-cutting) 艺术展。请给他写封邮件，内容包括：
Dear Mr. Henry,
I'm Li Hua, a Chinese student of yours. I'm writing to invite you to join me in visiting a paper-cutting exhibition, where you can have a close look at traditional Chinese culture as you always wish.
The exhibition will be held from 9:00 a.m. to 5:00 p.m. next Friday in Renmin Park, which is just two blocks away from our school. We can get there by taking Bus Line 101 or Subway Line 2.
As is advertised, there will be all sorts of paper-cutting unique to China on exhibition, and whoever present will be given a work of a paper-cutting as a gift. For someone so fond of Chinese culture like you, it is absolutely a great opportunity you can't miss.
Looking forward to your early reply.

My name is Li Hua. I would like to work as volunteer for 2022 Beijing-Zhangjiakou Winter Olympic Games. I'm a boy of eighteen years old from a high school. My spoken English is good and I can communicate with foreigners fluently. What's more, I have other advantages – I'm especially fond of sports, familiar with Beijing, good at communication and always glad to help others. I'm willing to provide the best service for every athlete in Winter Olympic Games. Therefore, I think I'm suitable for serving the Games.
I would appreciate it if you could offer me the chance to be a volunteer.
