Dear Mom and Dad,
¡¡¡¡How are you? I'm writing to you from my camp.
¡¡¡¡Yesterday we left our school at 8:00 a.m. The camp is only 200 miles from school. But there was someting wrong with our school bus on our way there, and it took three hours to fix it. So when we got there, it was already five p.m.
¡¡¡¡Ted and Brian both know how to use the computer. They are in Mr Smith's class to learn chess. I have to learn how to use the computer in Mr Brown's class with Walter. You know, we all live together and just share one room.
¡¡¡¡I have to design my own program this week. All of the campers have to. It's kind of difficult for me, but I think I will make it when the three-week camp is over.
¡¡¡¡We have to take part in two other activities every day. I am going to choose swimming and tennis with Brian. I like camping, but I don't like the food. It's very bad. We have to eat meals together in a very big room. When we are eating, there is always a lot of noise!
¡¡¡¡I have to say "goodbye" now. It's time to have lunch.
