Dear Jenny,

The opening of schools is put because of coronavirus and l have to study at home. Thanks to our teachers, I can have classes through the . Although I have to sit in front of the computer for hours every day and feel a little tired, it's to see and listen to different teachers. When I have questions, I ask my teachers for help or talk about them with my, friends on QQ or Wechat. I find even easier and more convenient to communicate with my teachers and friends online. Sometimes my parents also help me when I have problems. After class, l like to read my favorite books. I enjoy this special way of learning, but I'm also looking to meeting all my teachers and friends at school. Please write to me soon.

Yours,
