译文参考
亚马孙雨林：自然宝库
欢迎来到这片丛林，这是一片绿色的海洋，到处都可以听到动物发出的声音。这是亚马孙雨林。作为世界上最大的热带雨林，它在维持地球生态系统的良好平衡方面发挥着重要作用。
亚马孙雨林横跨南美大陆的八个国家，包括巴西、秘鲁以及法国的一个海外地区。亚马孙雨林面积约600万平方公里，相当于中国面积的一半以上。亚马孙雨林得名于亚马孙河。亚马孙河接近6 400千米，比长江还长约100千米。从山区流到海洋，这条河支撑着许多不同的生态系统。它们使这个地区拥有地球上最丰富的生物多样性：世界上已知的物种有十分之一在这里能够被发现。
在我们已知的39万种植物中，有4万多种能在亚马孙雨林中找到。高大而古老的巴西坚果树出产我们可以吃的坚果；这些睡莲大得可以让人躺在上面。雨林的不同层次使种类多到难以置信的野生动植物得以生存。在底部，有一个地表下的根系。在那之上是在黑暗的雨林地面上的大量落叶。再往上的一层是长着大叶的较矮的植物。然后是高耸而古老的阔叶树，最后是离地面好几米高的最高树木的树梢。雨林的每一层都形成了自己的小世界，成为各种生物的家园。
1 300多种鸟类和400多种哺乳动物藏身于亚马孙雨林的植物中。这只美洲豹就是一个例子。它长着一身带黑色斑点的黄褐色的皮毛。尽管相当多的美洲豹在这里生存，但它们仅是这个雨林食物链的一个要素。它们以包括青蛙在内的至少87种动物为食。相应地，这些青蛙以昆虫为食，而昆虫则吃树叶和水果。当美洲豹死亡时，一小群微生物帮助分解它的尸体，并将营养物质还给大地。
亚马孙雨林通过固定碳，并产生超过全球总量的20%的氧气，使得地球生生不息。因此，它经常被称为“地球之肺”。此外，亚马孙雨林还是一个有食用或药用价值的物种宝库。然而，这些不能替代的动植物面临着一个主要的危险：我们人类。在过去的50年里，由于农耕和养牛等人类活动，约17%的雨林已经消失了。随着人类活动的影响不断增加，濒危物种名单越来越长，这就留给我们一个问题：我们能承担得起损伤“地球之肺”的后果吗？

Dear Sir/Madam，
I'm writing to give some suggestions to protect the wildlife living in and around our city.
As we know，many species of wildlife are in danger of extinction.This is because the environment that they are living in has been destroyed greatly.They not only have little to eat，but also can be killed by human beings.
Personally，more measures should be taken to protect them from being hurt.Firstly，more laws must be made to stop people from cutting down trees.Secondly，all the factories must clean the waste water before it is poured into rivers or lakes.Thirdly，more reserves should be set up so that they can live safely.
I hope my suggestions are helpful.
Yours sincerely，
Li Hua

Good morning, everyone!
I'm very glad to give a speech today. The topic of my speech is Protect Wild Animals.
As we all know, wild animals also play a part in keeping the balance of nature. Unfortunately, they are in danger, and some of them are dying out. So it is urgent to take some measures to protect them. First of all, we must establish nature reserves. Secondly, it is important to raise public awareness of protecting wild animals. To harm wild animals is to harm ourselves. Therefore, let's take the responsibility and do what we can to protect them. I hope in the future we can live harmoniously and happily together with wild animals.
Thank you!
