This is the Amazon rainforest. As the largest rainforest in the world，it plays a significant role in② maintaining③ the fine balance of the Earth’s ecosystem④. The Amazon rainforest crosses into eight countries，including Brazil and Peru，and one overseas⑤ region⑥ of France，all on the South American continent⑦. 【1】 With an area of around 6 million⑧ square kilometres，the Amazon rainforest is more than half the size of 【2】 China. The Amazon River，from which the rainforest gets its name，【3】 is close to 6，400 kilometres in length⑨—roughly⑩ 100 kilometres longer than the Yangtze River. On its journey from the mountains to the ocean，the river supports many different ecosystems. They give this area the richest biodiversity on the Earth: one in ten known species in the world can be found here. 【1】画线部分由“代词＋介词短语”构成的独立主格结构。 【2】画线部分使用了“倍数＋the ＋名词(比较内容)＋of＋名词(被比较的一方)”的倍数表达法。 【3】画线部分是由“介词＋which”引导的非限制性定语从句，修饰先行词The Amazon River。 Of the 390，000 plant species known to us，more than 40，000 can be found in the Amazon. This tall and ancient brazil nut tree produces nuts that we can eat; these water lilies are big enough to lie down on．【4】The forest’s different levels support an unbelievable variety of wildlife. At the bottom，there is a system of roots beneath the ground. Above that is the mass of leaf litter on the dark forest floor．【5】 The next level is made up of shorter plants with large leaves. Then there are the towering ancient hardwoods，and finally the tops of the tallest trees many metres above the ground. Each level of the forest forms its own little world，home to different kinds of living things. 学生用书第3页 【4】画线部分为enough to do结构，意为“足以……”，lie down on的逻辑宾语为water lilies。 【5】画线部分是方位介词短语above that置于句首引起的倒装句。句中将谓语is置于主语the mass... 之前。 More than 1，300 species of birds and over 400 species of mammals hide among the jungle’s plant life. This jaguar is one example. It has a yellowish­brown coatwith black spots. While a significantnumber of jaguars survive here，they are only one elementof this forest’s food chain．【6】 They feed on at least 87 species，including frogs.These frogs，in turn，feed on insects which eat leaves and fruit. When a jaguar dies，a tiny army of microorganismshelps break down its body and return the nutrients to the earth. The Amazon rainforest breathes life into the planet by fixing carbon and producing over 20 per cent of all the Earth’s oxygen.Thus，it is often known as the “lungs of the planet”．Moreover，the Amazon rainforest is a treasure house of species that can be used for food or medicine. Yet there is one major danger to these irreplaceable plants and animals: us. Over the past 50 years，about 17 per cent of the rainforest has disappeared due to human activities such as agriculture and cattle farming. As the impact of human activities continues to grow and the list of species in danger of extinction becomes longer，we are left with a question: can we afford to damage the “lungs of the planet”？【7】 学生用书第4页 亚马孙雨林：大自然的宝藏 欢迎来到丛林，这是一片绿色的海洋，处处可闻各种动物的声音。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。 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，亚马孙河长约6 400千米，比长江还长大约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。 在人类已知的390 000种植物物种中，在亚马孙可以找到40 000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。雨林的不同层次养活的野生动物种类多到难以置信。最底层是地下的根系。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。雨林的每一层都自成一个小世界，成为各种生物的家园。 1 300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。尽管这里生存着数量可观的美洲豹，但它们仅仅是雨林食物链上的一环。它们捕食的物种至少有87种，其中包括青蛙。相应地，这些青蛙的食物，是以树叶和水果为食的昆虫。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。 亚马孙雨林通过固定碳(二氧化碳——译者注)，并生成占全球总量20%以上的氧气，来为地球注入活力。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，17%的雨林已经消失了。随着人类活动影响的不断增加，濒危物种的名单越来越长，这留给我们一个问题：我们能承担得起损害“地球之肺”的后果吗？ 一、整体理解 1．What’s the main idea of the passage?
