用书信的形式向朋友介绍上场次学校郊游的事写一篇英语小作文

Dear friend,
I want to invite you to the school ship.It must be really relaxed.We can swim in the river.And we can burn some barbecue.It's very decilious.And we can sing and dance,run in the forest.If you like drawing,you can draw anything you like.I think it's really fun.Do you want to join us ?

It is a sunny Sunday in spring,I went to the park with my classmates.We talked and laughed all the way to the park.When we reached the park,we went rowing on the beautiful lake as we planed.After that,we had our lunch on the grassland beside the lake.After we finished our picnic,we went for a walk along the bank and went home together after that.
