So nice to  listen to the students read  the whole speech.

This English speech  is inspiring, powerful and touching. We are the generation who are experiencing the fight against the corona virus so it's a natural  and necessary for us to have our own  memory , which is  special， unforgettable，and encouraging.

世界古古怪怪，学生可可爱爱

I am getting more and more interested in online teaching and learning. It's convenient to share all kinds of Information, various kinds of materials at the same time with many, many  people from different places.  at the same time it's convenient to get information from the Internet and  share it with my students.

So it's easy to get the latest materials and it will attract students  attention.

However, on the other hand, I have some worries about the online teaching and learning.  it takes too much time a day. And as a teacher I have to be online 24 hours a day. It makes me feel exhausted and tired.

I feel obviously that it does harm to our eyes.
