英语翻译
Not many years ago,some farmers were worried because hawks were taking many of their chickens.The farmers did not know what to do.Finally they went to the officials and asked for help.
"Kill the hawks,"the officials said."We'll even pay you for them."
So the farmers began to think of ways to kill hawks.
The farmers killed many hawks.Before long they didn't have to warry about their chickens.But they now had a new worry.Field mice ate a lot of the farmer's grain.How did this happen?Hawks eat not only chickens but also field mice.They eat more field mice than chickens.But the farmers did not know this.When they killed a lot of hawks,they changed the balance of nature.
When people move into a new place,they often destroy many wild plants.Many of these plants are food for the animals.If the animals cannot find enough plants to eat,they will starue(饿死)and have to leave the place.In one part of the United States,for example,the deer there like to eat a certain kind of wild rose.The mountain lions there eat the deer.The number of deer,mountain lions and wild roses does not change much if people leave things as they are.
But people killed many mountain lions in order to protect the deer.Soon there were so many deer that they ate up all the wild roses.Finally the deer began to eat the green leaves of young trees.These trees were important to the farmers.
So the farmers thought of ways to protect their trees.Now the deer had nothing to eat,and many of them died.This was another lesson from nature.
It is importaint for us to keep the balance of nature.This the lesson we should remeber.

几年前,一些农民都很担心,因为鹰会叼走他们很多鸡.他们不知道该怎么做.最后,他们向政府官员求助.
“把鹰杀了,”官员们说,“我们甚至可以付钱给你们.”
所以农民们开始计划杀鹰.
他们杀了很多鹰.不久前,他们就不需要为他们的鸡而担心了.但是他们又有了新的担忧,因为田鼠偷吃了很多粮食.这是怎么回事呢?由于鹰不仅吃鸡还吃田鼠.它们吃田鼠比吃鸡多.但是农民们不知道这事.在他们杀了很多鹰之后,他们破坏了自然地平衡.
人们搬到另个一地方后,经常清除野生植物.很多植物都是动物们的食物.如果动物们找不到足够的食物,它们就会饿死,而不得不离开这个地方.例如,在美国的一些地方,鹿喜欢吃某种野生玫瑰,而山狮吃鹿.如果人们不干涉它们,山狮,鹿和玫瑰还是和原来一样.
但是人们为了保护鹿而杀了许多山狮.很快,鹿就把玫瑰给吃光了.最后鹿就开始吃小树的绿叶.这些树对农民来说很重要.
所以这些农民想了很多方法来保护他们的树.现在,鹿没有东西可吃,很多都死掉了.这是自然给人类上的另一课.
对我们来说,保护自然平衡很重要.我们应该记住这一课.
