作文:假如你是李华，你在网上结识了一位来自澳大利亚的观星爱好者Mark。根据以下信息，给他写一份邮件，介绍你校组织的一次

Dear Mark, I’m writing to tell you a stargazing activity that I took part in last Sunday. I’m sure you will be interested in it. That night we camped at the top of a hill near our school, waiting patiently for the falling stars. We chose the hilltop, because it was far away from city lights and we could observe them very clearly. When the first falling star fell from the sky, we became so excited that we all shouted with joy. The bright falling stars lightened the sky. After a while, we realized we should take photos of the amazing scene. Could you imagine how excited we were at that moment? Do you have a similar experience? Yours, Li Hua
