[2]“介词from＋which”引导非限制性定语从句，which指代先行词the Amazon River，在句中作from的宾语。 ②overseas /ˌəʊvəˈsiːz/ adj.海外的，国外的 adv.在海外，在国外 ③region /ˈriːdʒən/ n.地区，区域；行政区 ④continent /ˈkɒntɪnənt/ n.大陆，陆地，洲 ⑤million /ˈmɪljən/ num.一百万；许多，大量 ⑥length /leŋθ/ n.长，长度；时间的长短；篇幅，(电影)片长 ⑦biodiversity /ˌbaɪəʊdaɪˈvɜːsəti/ n.生物多样性 ⑧species /ˈspiːʃiːz/ n.(pl.species)种，物种 亚马孙雨林横跨8个国家，包括巴西和秘鲁，还有法国的一个海外地区，都在南美洲大陆上。亚马孙雨林面积约为600万平方千米，面积超过中国国土面积的一半。亚马孙雨林得名于亚马孙河，亚马孙河长接近6 400千米，比长江还长约100千米。这条河流经过高山注入海洋，维系着许多不同的生态系统。它们赋予这个地区地球上最丰富的生物多样性：世界上十分之一的已知物种都能在这里找到。 　　Of the 390，000 plant species known to us，more than 40，000 can be found in the Amazon.This tall and ancient brazil nut⑨ tree produces nuts that we can eat[3]； these water lilies⑩ are big enough to lie down on[4] .The forest’s different levels support an unbelievable variety⑪ of wildlife⑫.At the bottom，there is a system of roots beneath⑬ the ground.Above that is the mass⑭ 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 towering⑮ ancient hardwoods⑯，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 living⑰ things.

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 disappeared㉛ due to㉜ human activities such as agriculture㉝ and cattle㉞ farming. As the impact㉟ of human activities continues to grow and the list of species in danger of extinction㊱ becomes longer[8]，we are left with a question：can we afford to damage㊲ the “lungs of the planet”？ [7] that引导定语从句，修饰先行词species。 [8] as引导时间状语从句，表示“随着……”。 ㉗breathe life into给……带来起色，注入活力 ㉘carbon /ˈkɑːbən/ n.碳 ㉙oxygen /ˈɒksɪdʒən/ n.氧，氧气 ㉚thus /ðʌs/ adv.因此，从而；这样 ㉛disappear /ˌdɪsəˈpɪə(r)/ vi.不复存在，灭绝，消亡；消失；失踪 ㉜due /djuː/ to 由于，因为 ㉝agriculture /ˈæɡrɪkʌltʃə(r)/ n.农业，农学 ㉞cattle /ˈkætl/ n.牛 ㉟impact /ˈɪmpækt/ n.影响，作用；撞击，冲撞 /ɪmˈpækt/vt.& vi.有影响；冲击 ㊱extinction /ɪkˈstɪŋkʃn/ n.灭绝，绝种 ㊲damage /ˈdæmɪdʒ/ n.& vt.损坏，破坏，损害，伤害 　　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，它通常被称为“地球之肺”。此外，亚马孙雨林是一个物种宝库，这些物种可用于食材或药材。然而，这些不可替代的动植物面临一个大危险：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？ 1.Match the main idea with each paragraph.

Auditory (听觉的) parts of the brain connect to areas important for development and the regulation of emotion and learning，so it’s likely that noise could disrupt healthy growth.Mariette says she would like to conduct other experiments to learn what aspects of noise are harmful.For example，it could be that hearing constant sound without any rhythm—unlike song—is somehow stressful. [语篇解读]　本文是一篇新闻报道。研究揭示，交通噪声对雏鸟发育造成负面影响，包括降低孵化率、生长迟缓及减少后代数量。 1.What does the underlined word “nestlings” in paragraph 2 mean？ A.Baby birds.　　　　　　　 B.Sick birds. C.Mothr birds. D.Birds’ eggs. 1 2 3 4 解析：词义猜测题。根据画线词所在句“Researchers already knew...care for their nestlings.”可知，过多的噪声会干扰繁殖中的鸟类，那么结果就是使父母对它们的幼鸟沟通和照顾变得更为困难。由此可以推断，画线词“nestlings”指的是前半句中的“breeding birds”，即幼鸟。故选A项。 答案：A 2.Why did Mariette and her team conduct the experiment？ A.To test the volume of noise on campus. B.To answer a question about zebra finches. C.To compare road noise with zebra finch songs. D.To examine the influence of noise on little birds. 答案：D 1 2 3 4 解析：细节理解题。根据第二段中的“But it wasn’t...harm young birds.”和第三段中的“Mariette，a behavioral ecologist...in Melbourne，Australia.”可知，研究人员已经知道，太多的噪声会干扰正在繁殖的鸟类，使父母更难与雏鸟沟通和照顾它们，但是他们不知道噪声本身是否会直接伤害幼鸟，Mariette和她的团队进行实验的目的是考察噪声对小鸟的影响。故选D项。 1 2 3 4 3.How did the noise affect the birds’ growth according to the experiment？ A.It made them less stressful. B.It prevented the birds having babies. C.It led to the slow growth of the birds. D.It reduced parent birds’ red blood cells. 1 2 3 解析：细节理解题。根据第四段中的“Those exposed to...were under stress.”可知，噪声导致了小鸟的生长缓慢。故选C项。 答案：C 4 4.What is Mariette most likely to study next？ A.Functions of the auditory parts of birds’ brains. B.The harmful parts of noise to young birds’ growth. C.The impact of rhythmic sounds on birds’ development. D.The impact of traffic noise on birds’ emotion and learning. 1 2 3 4 解析：推理判断题。根据最后一段中的“Auditory parts of...noise are harmful.”可知，Mariette接下来最可能研究的是噪声的哪些部分对小鸟的成长有害。故选B项。 答案：B B 　　We are in Wollemi National Park，north of Sydney，Australia.It’s September 1994.Imagine a forest ranger (护林员) walking in the wilderness.His name is David Noble.He climbs down to a remote deep valley and sees something that he will never forget. 　　In front of him is a strange forest of unusual trees.The tallest trees are almost 40 meters high，and the base diameter (底部直径) of their trunks is about one meter.The trees do not have the leaves that we usually see and look a bit like giant ferns (蕨类植物) with green branches.Deeply impressed by the unusual trees，David picks up a dry branch from the ground and puts it in his backpack.He stays under these strange trees for a while and then continues his hike. 　　David’s chance finding that day became one of the most significant botanical finds in 100 years，as the ancient tree species was thought to be extinct millions of years ago.In fact，it is so unbelievably rare that it has since been compared with finding a small dinosaur still alive on Earth. 　　So there are ancient dinosaur trees in Wollemi National Park.The tree is named Wollemia Nobilis.The Park takes immediate action to protect the trees.Only a few researchers are allowed to see them.They are taken to the deep valley by helicopter，and before they get there，their eyes are covered.Crowds of visitors will no doubt destroy the trees，but natural disasters，for example，forest fires，can also threaten them. 　　Now the Wollemia environmental protection effort is in full swing.Wollemia seeds are on sale.Young Wollemias pop up in homes，gardens and parks around the world.Those who want to see the endangered species don’t have to search for their natural habitat.Instead，they can see the trees in parks closer to home. [语篇解读]　本文是一篇说明文。文章介绍了护林员David Noble在1994年在沃勒米国家公园发现了一种被认为已灭绝的古老树种--凤尾杉。这一发现极为重要，公园采取了保护措施。如今，凤尾杉已经被广泛种植，使得这种濒危物种在世界各地的公园中得以被观赏。 5.What makes David pay special attention to the trees？ A.Their habitat. B.Their size. C.Their history. D.Their features. 5 6 7 8 解析：细节理解题。根据第二段中的“The tallest trees are almost 40...with green branches.”可知，这些树与众不同的特征使David特别注意到它们。故选D项。 答案：D 6.Why is the discovery of Wollemia Nobilis considered important？ A.It is regarded as the most precious plant. B.It was believed to be an extinct species. C.It looks much more like a small dinosaur. D.It has grown in the deep valley for centuries. 5 6 7 8 解析：细节理解题。根据第三段中的“David’s chance finding...millions of years ago.”可知，凤尾杉的发现被认为重要的原因在于它被认为是一种灭绝的物种。故选B项。 答案：B 7.What action does the Park take to protect the trees？ A.Employing strict access measures. B.Permitting nobody to enter their habitat. C.Encouraging researchers to clone them. D.Relocating the trees to prevent forest fires. 5 6 7 8 解析：细节理解题。根据第四段中的“The Park takes immediate...their eyes are covered.”可知，该公园采用严格的准入措施，以保护该树种。故选A项。 答案：A 8.What is a suitable title for the text？ A. Timeless Trees：An Australian Mystery B.The Hidden Forest：Discovered in Australia C.Lost and Found：Australia’s Prehistoric Survivor D.Ancient Ferns：A Discovery in Australia’s Wild 5 6 7 8 答案：C 解析：标题归纳题。通读全文可知，文章围绕凤尾杉展开，介绍了这一被认为已灭绝的古老树种的发现、保护和繁盛的情况。因此，C项“遗失与发现：澳大利亚的史前幸存者”契合文章主旨，适合作为文章标题。故选C项。 5 6 7 8 C 　　I adopted Motley from the SPCA six years ago.When I first brought him home，he was scared of everything.Cars terrified him because he had never experienced traffic before.Toys were so foreign to him that he would shake in fear.He would often spend hours by himself hiding in rooms that I wasn’t in，or in his corner.Play was something he didn’t understand either. 　　Two years ago，my husband and I adopted a Bichon named Freddie.Freddie is the polar opposite of Motley.He is vigorous and cannot stay in one spot for more than a minute or two.He loves chasing toys and playing with us.He is interested in everything.Taking walks is his favorite activity. 　　At first，Motley wanted nothing to do with him.Freddie was determined.He kept trying to play with Motley，until Motley finally caught on，and for the first time in his life he engaged in play.Motley was confused as to why Freddie was interested in chasing toys.One day，Motley ran after one of them and held it in his mouth.He didn’t know what to do with it，but it was a start. Motley began chasing Freddie around，so he wasn’t in a corner by himself as much.As soon as Motley figured out that Freddie was getting to spend more time outside，he became interested in walking. Some days he is excited enough to walk that he is suddenly pulling us to the sidewalk.Motley learns new things from Freddie every day and is a completely new dog.We adopted Freddie as a present for ourselves，but he turned out to be more of a present for Motley.
