To celebrate Earth Day this year, our school started an environmental activity—Environmental Protection Week. It lasted from April 16th to 22nd. I took part in some activities during the week. On April 18th, I listened to a speech about how to protect the Earth in our daily life. On April 20th, I helped clean up the Children’s Park together with my classmates. At the end of the week, our teachers took us to the hill nearby to plant trees. We planted 150 trees in total.
