　　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。这里是亚马孙雨林。作为世界上最大的雨林，它在维系 地球生态系统的微妙平衡上扮演着举足轻重的角色。 目 录 英语·必修第三册（YL） 　　亚马孙雨林穿过包括巴西、秘鲁在内的八个国家，以及一块 法国的海外领地，都位于南美洲大陆。亚马孙雨林的面积约为600 万平方千米，比中国国土面积的一半还要大。亚马孙雨林得名于 亚马孙河，亚马孙河长接近6400千米，比长江还长约100千米。这 条河从高山流向海洋，沿途维系着多种不同的生态系统。它们赋 予这片区域地球上最丰富的生物多样性：全世界十分之一的已知 物种，都可以在这里找到。 目 录 英语·必修第三册（YL） 　　在人类已知的390000种植物物种中，在亚马孙可以找到40000多 种。这棵高大、古老的巴西坚果树结出的坚果我们可以食用：这些睡 莲（叶片）大到可以躺在上面。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。往上是阴暗 森林地表厚实的落叶层。再往上一层由低矮的阔叶植物组成。然后是 高耸、古老的阔叶树，最后是那些离地数米之高的大树的树冠。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。 目 录 英语·必修第三册（YL） 　1300多种鸟和400多种哺乳动物藏身于这片丛林的植被中。这只美 洲豹就是个例子。它黄棕色的皮毛上遍布着黑点。尽管相当多的美洲 豹在这里生存，但它们只是这个雨林食物链上的一个要素。它们捕食 的物种至少有87种，其中包括青蛙。相应地，这些青蛙以昆虫为食， 而昆虫则吃树叶和水果。美洲豹死后，一小支微生物军队会助力其尸 体的分解，让营养素重回土壤之中。 目 录 英语·必修第三册（YL） 　　亚马孙雨林通过固定碳，并产生超过全球总量20％的氧气，使得 地球生生不息。因此，它也常常被称作“地球之肺”。此外，亚马孙 雨林还是食用物种和药用物种的宝库。然而，这些无可取代的动植物 面临的一个主要威胁就是：我们。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，濒危物种的名单越来越长，这就留给我们一个问题：我们能承担 得起损害“地球之肺”的后果吗？ 目 录 英语·必修第三册（YL） 文本透析·剖语篇 目

These smart mammals seem to enjoy our company and interact （互动） with us.But is it possible that this kind of human activity putting their survival at risk？ 目 录 英语·必修第三册（YL） 　　A recent study has shown that the behavior of whales and dolphins changes greatly when they are close to boats.Interpreting （诠释） the boats as a possible danger，they start to breathe more quickly.The boats drive them away from the places where they feed and interrupt （打扰） their routine （日常生活） of resting and taking care of their young.All of these factors could have a very negative effect on their general health.Another factor that should be taken into account is the effect of human attention on the animals.As they become more used to interacting with humans， they become less afraid of them.There have been several cases of tour boats running into dolphins or whales and causing their deaths.As dolphins live within close communities，events like these cause a lot of stress. 目 录 英语·必修第三册（YL） 　　Perhaps the best way to protect these animals is to reduce our interaction with them.We could do this by keeping a minimum distance between the animals and the boats， and by limiting the number of boats out on the water at one time.Most importantly， instead of interrupting these animals’ routines， we should try to adapt to them.In this way， we could learn to stay in harmony with these wild animals and ensure our continued co-existence on the planet that we shall share. 语篇解读：本文是一篇说明文。文章就生态野生生物旅游越来越受 欢迎的现象论述了要想与野生生物和谐相处，就要减少与它们的互 语篇解读：本文是一篇说明文。文章就生态野生生物旅游越来越受 欢迎的现象论述了要想与野生生物和谐相处，就要减少与它们的互动。 目 录 英语·必修第三册（YL） 5.

It takes 14 million trees to meet this demand. B. They can be reused for groceries several times. C. Paper bags and plastic bags have their own strengths. D.
