Good morning, everyone, I am Li Hua from Xinhua Middle School. It is my great honor to give a speech here. My topic is“China's aid to other countries”. 
In 2020, during the spread of COVID-19, China made the effort to aid other countries suffering from the epidemic. On the one hand, China volunteered to provide a large quantity of medical supplies for them. On the other hand, China strengthened medical cooperation with them. Not only did China share the ways to treat the disease, but also it sent medical teams to some countries.
Today, I want to relay to you that China deserves the respect of the whole world. I pray that the whole world can overcome COVID-19 soon.
Thanks for your listening! 

Hello, everyone! I'm glad to have this chance to share some ideas about garbage classification with you.
To my understanding, the earth is home to every individual, and it's our duty to protect the environment voluntarily. By sorting the waste, we can not only reduce pollution but also save energy, which will pave the way for the recycling of valuable resources.
For the sake of our environment and life, we are expected to learn to sort the rubbish and make it a habit.
Thank you!
