I had a great school trip last weekend.I went to the aquarim for the day.First I went to the Visitors' Center and watched a movie about sharks.Then I watched a dolphin show.After that ，I wet to the outdoor Pool and saw a big octopus.The octopus is very interesting.I saw it for the first time.It has many hands or feet,At the end of the day ,we took the bus to school.We all tired ,but we all happy.
