Dear Mr Eric,

　　I came to see you this morning but it so happened that you were out.So I have to leave this note to you.

　　I'm so glad to tell you that after raining so many days,it is said to be fine this Sunday.Therefore some of my friends and I have decided to go for an outing.We'll meet at the gate of the Forest Park at 8:30 a.m.Then we'll go climbing and have some games.We'll have a picnic.In the afternoon we'll go boating in the river nearby.If possible,we'll go to pick some wild fruits.I'm sure we'll take some photos,too.Will you join us? We'll be very happy if you will.Ring me up before 5 p.m.,please.

　　Your,

　　Wang Gang
