A lot of families will choose to take their children to the zoo when they have time, because they can broaden the children's vision and gain the knowledge about the animals. But the problem is that some parents give the food the children and admit them to throw it to the animals. It is harmful to the animals. We should behave ourselves. 
許多家庭當他們有時間的時候會選擇帶他們的孩子去動物園玩，因爲這樣可以拓寬孩子們的視野並獲得有關動物的知識。但問題是，有些父母給孩子們食物，並允許他們向動物投放食物。這樣做對動物是有害的。我們應該自律。
