Last weekend, I went to the zoo with my classmates. We saw a lot of animals. First, we saw the elephants. They were very big. They moved slowly and quietly. Then we saw the kangaroos. I enjoyed watching them because they jumped very high and ran quickly. In the end, we went to see the monkeys. They looked funny. They swung from tree to tree all the time. They jumped up and down on the trees very quickly. We had a really good time.
