【三年级暑假趣事英语作文:Summer（Holiday及作文400字）】Last summer holiday was very fun for me. I had a lot of interesting things to do. My family and I went to the beach. It was sunny and warm. We played in the water, built sandcastles, and had a picnic on the beach.

I also visited my grandpa in the countryside. There, I helped him feed the chickens and collect eggs. I even learned how to ride a bike! At first, I was scared, but after a few tries, I could ride it by myself. That made me very happy.

One day, I went swimming with my friend Lily. We swam in the pool and played games. After swimming, we ate ice cream and talked about our favorite cartoons. It was a great day.

I also read some books during the vacation. I liked a story about a little rabbit who went on an adventure. It was exciting and made me laugh a lot.

The summer holiday was short, but I had so much fun. I hope next summer will be just as good. I will remember these happy days forever.
