【正确答案】Dear Chris,
How is everything going? I' m so glad to tell you a good news. We will have a wonderful trip and I want to invite you to join our team. This Sunday, we will have a sunny day. It' s good for mountain climbing and camping. We can go on a picnic at the foot of the mountain. I believe the scenery at the foot of the mountain must be beautiful.
We are going to take a bus to the World Park and we will meet at the school gate at 8:30 on Sunday. You'd better use sunscreen and take an umbrella to avoid sunburn. Don't you think it sounds great? Looking forward to your arrival.
Yours truly,
