last thursday, we had a class meeting to discuss where to go for our spring outing. we came up with several choices such as going boating, climbing a mountain, and going to an amusement park. finally, we decided to go mountain climbing.

　　the next day, we set off early in the morning. while climbing the mountain, we enjoyed the warm sunshine and a beautiful view . however, when we reached the top, we were shocked to see litter here and there, such as bottles and banana peels. then we started to pick up the litter and put the rubbish into the nearby recycling bin and non-recycling bin respectively.

　　we were tired but happy.
