The Amazon rainforest: a natural treasure
[1]Welcome to the jungle, a huge sea of① green alive with② the sounds of animals.This is the Amazon rainforest.[2]As the largest rainforest in the world, it plays a significant role in③ maintaining the fine balance of the Earth’s ecosystem④.
[1]句中a huge sea of green alive with the sounds of animals是名词the jungle的同位语。
[2]动词-ing形式短语maintaining the fine balance of the Earth’s ecosystem作介词in的宾语。
[3]The Amazon rainforest crosses into eight countries, including Brazil and Peru, and one overseas region⑤ of France, all on the South American continent⑥.[4]With an area of around 6 million⑦ square kilometres, the Amazon rainforest is more than half the size of China.[5]The Amazon River, from which the rainforest gets its name, is close to 6,400 kilometres in length⑧— roughly 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 biodiversity⑨ on the Earth: one in ten known species⑩ in the world can be found here.
[3]句中all on the South American continent是独立主格结构(代词+介词短语),在句中作状语。
[4]句中With an area of around 6 million square kilometres是with复合结构作状语;more than half the size of China 是倍数表达法之一,其结构为“倍数+the size of+被比较的对象”。
[5]“介词(from)+which”引导非限制性定语从句,which指代先行词The Amazon River。
[6]Of the 390,000 plant species known to us, more than 40,000 can be found in the Amazon.This tall and ancient brazil nut⑪ tree produces nuts that we can eat; these water lilies⑫ are big enough to lie down on.The forest’s different levels support an unbelievable variety⑬ of wildlife⑭.At the bottom, there is a system of roots beneath⑮ the ground.

[6]句中known to us为动词-ed形式短语作后置定语,修饰名词短语the 390,000 plant species。
[7]本句是完全倒装句。表示地点、方位的介词短语Above that置于句首,句子用完全倒装结构。
More than 1,300 species of birds and over 400 species of mammals⑳ hide among the jungle’s plant life.This jaguar㉑ is one example.It has a yellowish-brown coat with black spots.[8]While a significant number of jaguars survive㉒ here, they are only one element of this forest’s food chain.They feed on at least 87 species, including frogs.These frogs㉓, in turn㉔, feed on insects which eat leaves and fruit.When a jaguar dies, a tiny army of microorganisms㉕ helps break down㉖ its body and return the nutrients㉗ to the earth.
The Amazon rainforest breathes life into㉘ the planet by fixing carbon㉙ and producing over 20 per cent of all the Earth’s oxygen㉚.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 irreplaceable㉛ plants and animals: us.[9]Over the past 50 years, about 17 per cent of the rainforest has disappeared㉜ due to㉝ human activities such as agriculture㉞ and cattle㉟ farming.[10]As the impact㊱ of human activities continues to grow and the list of species in danger of extinction㊲ becomes longer, we are left with a question: can we afford to damage㊳ the “lungs of the planet”?

亚马孙雨林:大自然的宝藏
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。
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。
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。
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。
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?

2.美文欣赏——赏佳句,品用法
课文The Amazon rainforest: a natural treasure的语篇类型是纪录片脚本。纪录片脚本的语言作为电视语言中的一种,有其独特的风格。
(1)从人称和语气的角度看:作者大量使用第三人称,力求展现出真实的亚马孙雨林。但也少量使用了第一人称来拉近和读者的距离,引发读者共鸣。多使用陈述语气,有时也会使用疑问句,但其作用与其说是向读者提问,不如说是在引发读者的思考。例如,文章最后一段中的句子
。
(2)从语体风格来看:本文是阐释型纪录片,本质上属于说明文,内容科学、结构严谨、语言严密准确。例如,第二段中的句子
,作者使用了列数字和作比较的说明方法,帮助读者对亚马孙雨林的面积留下具体而鲜明的印象。另一方面,该脚本也借用了一些修辞手法来使其语言形象贴切,提升艺术感染力。例如,最后一段中的句子 ,作者把亚马孙雨林比作“地球之肺”,使其重要性跃然纸上。

【用法】

①根据定语从句中动词或形容词等的某种习惯搭配来确定;
②根据与先行词搭配的具体意义来确定;
③根据所表达的意思来确定;
④表示“所有”关系或“整体中的一部分”时,通常用介词of。
(3)基本形式:
①“介词(短语)+关系代词”(作状语):关系代词只能用which或whom且不能省略,但可与关系副词互换;
②“介词+关系代词+名词”(作状语):关系代词常用which 和whose;
③“名词/代词+介词+关系代词”(作主语):可转化为“whose+名词”结构;
④“数词/形容词最高级+of+关系代词”(作主语):数词还可以被some, many, most, each等不定代词替换。
