Недавно я ходила в зоопарк .Это прекрасное место. Там было много разных животных,такие как медведи,жирафы,слоны,бегемоты и много разных птиц. Но павлин мне понравился больше всего. Мне очень понравилось в зоопарке. Я бы хотела пойти в этот удивительный мир животных снова. 
Recently I went to the zoo.It is a wonderful place. There were a lot of different animals such as bears, giraffes , elephants , hippos and many different birds. But I liked the peacock the most.This is a very proud animal. I really enjoyed the zoo. I would like to go into this amazing world of animals again.
