Last Sunday，we had a class trip to enjoy．Our head teacher took us to thefor a picnic．When we arrived there at 9：00 am by bus，we heard a big sound．It was made by the wind and the waves(海浪)．It sounded like they were playing wonderful symphony(交响乐)．

    Right away，we sat down and started to enjoy our picnic．We told jokes，sang and played games while sandwiches，chocolate and other snacks．In the afternoon，some students chased(追逐)each other in theand swam for fun．Alice and I attempted to catchin the water．Some students helped the cleanersup the rubbish．Others played cards and chess．Everyone looked extremely．

    At 4：30 pm，we had to go back to school，we wanted to spend some more time on the beach. Just then, I found a blue hair band on the sand．"I think Alice dropped it" Sam said， "because she likes thecolor．"But I thought itbelong to her because I saw her wearing a yellow one．At last, we knew it was Cindy's．We went back to school at 5：45 pm．The picnic came to an end．but we'll always remember the good time we had．
