Dear Mary
Hello, I'm Lihua. There a knowledge contest will be held by our school about fighting against the natural disaster next Friday afternoon on our school playground.
All the students in our school will be requested to join in this competition. Stuents will be divided into several groups to see which group can answer the question ads far as possible. And the competition will last for 4 hours. So we should make full preparation for it. Our school will reward ten students who can win the competion.
It is helpful for us to hold this activity. From the contest, we can learn what to do when we come across some disaters. I think it excited. It sounds great, right? Do you want to jion the competion with me ? I hope we can fight side by side together. I am waitting for your letter.
Best wishes.
Yours,
LiHua
