Dear Smith,
I have a good news for you. All senior three students will take part in a mountain- climbing activity in May 18th, which is intending to help reduce our pressure from study. So I’m writing to invite you to go along.
We plan to gather at the school gate at 8:20, weather permitting. Then they will set off at 8:30, heading for the mountains nearby on feet. After having a good time, we are supposed to go back school for lunch at about 12.
The suggestions are as following. You’d better wear strong and comfortably shoes so that you can enjoy the trip. A bottle of water and some snacks were also necessary in climbing. In addition, you can take with you a camera to get some photos taken.
Look forward to your reply.
Yours,
Li Yan
