Ladies and gentlemen:
Good morning! Today, the title of my speech is A Lesson from Nature.
Around us , there are plants, animals and many other things. We live in nature, so to keep the balance of nature is very important for us. But today, too many trees are still being cut down in many countries and flood all over the world are getting more and more serious, A lot of land has gone with them. This is a lesson from nature.
When people move into a new place, they often cut down trees or pull out many wild plants to make farmland. They don’t know that trees can stop flood and wind from washing or blowing the earth away, and that many of these wild plants are food for some wild animals. If the animals can’t find enough plants to eat, they will die or have to leave the place.
In one part of the United States, for example, the deer there like to eat a kind of wild flowers. The mountain tigers there eat the deer. But people killed many mountain tigers to protect the deer. soon there were so many deer that the ate up all the wild flowers. Then the deer began to eat the green leaves of the young trees .so the farmers thought of ways to protect their trees, then the deer had nothing to eat and many of them died.
The number of trees, deer, tigers, wild flowers and plants has changed much—less and less. We need to do more to keep the balance of nature.
Thank you!
女士们，先生们：
早上好！今天，我演讲的题目是一个自然的课程。
在我们身边，有植物，动物和许多其他的东西。我们生活在自然中，所以保持自然的平衡对我们来说非常重要。但是今天，许多国家和地区的许多国家和地区的洪水都越来越严重，许多国家和地区都越来越严重，许多国家都在和他们一起走了。这是一个自然的教训。
当人们进入一个新的地方，他们经常会砍伐树木或拔出许多野生植物来制造农田。他们不知道，树木可以阻止洪水和风吹走地球的距离，而许多野生植物是一些野生动物的食物。如果动物找不到足够的植物吃，他们就会死亡或离开的地方。
在美国的一个部分，例如，鹿有喜欢吃一种野生花卉。山虎在那里吃鹿。但人们杀了许多山虎保护鹿。很快，有那么多的鹿，吃了所有的野生花卉。于是鹿开始吃小树的绿叶，于是农民们想办法保护他们的树木，于是，鹿什么也吃不到，他们中的许多人都死了。
树木、鹿、老虎、野生花卉和植物的数量变化不多，也越来越少。我们需要做更多的事情来保持自然的平衡。
谢谢你！
