Last Sunday,my sister and I paid a visit to the GuangMing zoo .There were so many animals in it,We pandas,tigers ,monkeys,elephants and so on,but when we walked to the monkey cage,we saw a visitor was throwing snacks(food) to the monkeys,so we went forward to prevent him doing that,and told him what he did was not right,At last ,he said sorry to the monkeys and us,We were so happy!
