Dear John,
Thank you for your kind letter. You told me that you and most of you classmates went out for a three-day trip. I really think it fun. Now let me tell you something about a speech contest, which I have taken part in.
The contest was held at the playground last Saturday morning, The panel is made up of 5 English teachers from our school, all of whom were experienced. Moreover, a total number of 20 competitors came from we Grade  It was made a rule that the top 3 competitors would be awarded. It is a great competition and all the participants perform well. I was so lucky that I won the first place.
I will end here and hope to hear from you very soon.
Best wishes.
