帮我看看这篇作文有语法上的错误吗.
Last weekend ,I had picnic with my parents.We went to a countryside.We took some sandwiches and some bottle of water.Of course,I didn't forget to take some snacks.
At 8:0 am,we came to a nice place.It was near a river.The weather was hot,so I wanted to swim.The water made me refreshed.My parents talked under the tree.
About one hour later,wo took out the foot and had our picnic under the tree.I chated with my parents.There was smile on everyone's face.I was really happy,because my parents were always busy.
I gained happiness from this picnic.I think this is a good way to get on better with parents.
