Last Thursday, we had a class meeting to discuss when to go for our spring outing. We came up with several choice such as going boating, climbing a mountain and going to a amusement park. Final, we decided to go to mountain climbing. The next day, we set off early in the morning. While climbing the mountain, we enjoy 
the warm sunshine and a beautiful view. Therefore, when we reached the top, we were surprising to see litter here and there ,such as bottles and banana peels. Then we started to pick up the litter. Afterwards, we put the rubbish the nearby recycling bin and non-recycling bin respectively.
We were tired and happy.
