It was Sunday yesterday. But Sally and I decided to visit the Xi’an Zoo, where is only four kilometres from our school. At nine in the morning, we waited the bus at the bus stop. After 15 minutes or so, we got on the No. 10 bus excited. On arrival, we find the zoo crowding with people, students, workers , villagers and so on. Most of them was young parents with his children. There were many kinds of animals in the zoo. They were elephants, bears, lions, monkeys and the beautiful birds. Children liked the monkeys very much. At 12 o’clock, we returned back home. What good time we had at the zoo!
