Unit 5　A delicate world
【话题导入】
In a world with limited land, water and other natural resources①， the harm from the traditional business model is on the rise②. Actually, the past decade has seen more and more forests disappearing and the globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable③ ways. That means growth with low carbon or development of sustainable products. In other words④， we should keep the earth healthy while using its supply of natural resources.
Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low carbon energy will become three times bigger over the next decade. [1]China, for example, has set its mind on⑤ leading that market, hoping to seize chances in the new round of the global energy revolution⑥. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high speed trains.[2]In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil (棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions⑦ and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up⑧ the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate⑨ the change from traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant⑩ new chances for sustainable product industries.

MACQUARIE ISLAND：
from Chaos① to Conservation
I am standing on Macquarie Island, in the South west Pacific Ocean, halfway② between Australia and Antarctica. Strong winds③ and stormy seas④ have helped sculpt⑤ its long, thin shape. The green grass and bare rock of its landscape contrast dramatically⑥，[1] giving it a wild and natural beauty. No visitor would think it surprising that the island is a UNESCO World Heritage⑦ Site. [2]Nor would they fail to⑧ imagine how its native inhabitants⑨， including royal penguins, king penguins, and elephant seals, existed in perfect harmony with⑩ their natural habitat for thousands of years.
[1]此处为v. ing短语作结果状语。
[2]本句为主从复合句。主句中，否定词Nor位于句首，句子采用了部分倒装；how引导宾语从句，作imagine的宾语。
But the island's more recent history tells a different story .[3]It's a tragic story that began in 1810 when humans arrived on the island.In their ships they unknowingly brought rats and mice . These small animals quickly took over the island, [4]eating the birds' eggs and attacking baby birds．Cats were brought to the island to control the rats and mice.Unfortunately, the cats subsequently developed an appetite for the birds, too.
[3]本句中的It指的是前面的a different story。that在此引导定语从句，修饰先行词a tragic story；该定语从句中又包含一个when引导的定语从句，修饰1810，when在此定语从句中作时间状语。
[4]此处的“eating the birds' eggs”和“attacking baby birds”是and连接的两个并列的v. ing短语，在句中作伴随状语。
Meanwhile, rabbits were introduced to the island as a source of food for humans.Loose on the island, they did what rabbits do best—they multiplied rapidly and began eating the native vegetation and digging holes, which caused soil erosion. The exploding rabbit population provided plentiful food for the cats, meaning that the number of cats also increased. This in turn led to more cats hunting the birds. [5]The end result was that parakeets, once large in number and native to the island, died out in 1891.
Even after Macquarie Island became an official nature reserve in the 1970s, the rabbits remained out of control. Experts felt it necessary to come up with a plan to remove all the rabbits from the island.[6]With this goal in mind, a virus was released onto the island. But although the virus caused the rabbit population to decrease from 130，000 to around 10，000, it also meant less food for the cats. The cats in consequence turned their attention—and their stomachs—back to the native birds, killing up to 60，000 each year. In the 1980s, traps and dogs were used to catch the cats. The last Macquarie Island cat was caught in 2000.
[6]此处属于with复合结构，介词短语in mind作宾补，该结构在句中作状语。
[7]But as the saying goes，“While the cat's away，the mice will play.”With the departure of the cats from the island, the mouse and rat population started to increase. And remember those 10，000 or so rabbits It turned out that they developed an immunity to the virus, and their numbers exploded once again. Then, in 2006, the rabbits' digging caused some land to collapse, and killed a substantial number of penguins. This incident made it clear that the rat, mouse and rabbit problem needed solving once and for all.
[7]此处是as引导的非限制性定语从句，as代替后面的句子。
So，I am here on Macquarie Island to participate in the programme to tackle this very problem. The first step involved poison being dropped from helicopters. The next step is to remove the last remaining invading species, and that's where I come in—with my dogs. They have been trained to find every last one, without harming the native animals. This intervention is a long, much delayed ending to a sad story, but we humans owe it to the island to give it a happy ending.
Postscript: In 2014, Macquarie Island was declared pest free and the island's ecology is finally on the road to recovery.
麦夸里岛：从紊乱到保护
我此刻正站在麦夸里岛上，它位于太平洋西南部，澳大利亚和南极洲中间。强风以及波涛汹涌的大海使它形成了细长的形状。青草和裸露的岩石地貌形成了鲜明的对比，赋予这座岛一种野性和自然的美。这座岛屿被联合国教科文组织列为世界遗产保护区，任何游客都不会对此感到意外。他们也不难想象出那里的当地物种，包括帝企鹅、王企鹅和象海豹，数千年来是如何与它们的自然栖息地和谐共存的。
不过，这座岛屿更近期的历史讲述的情况迥然不同。那是一个始于1810年的悲剧故事，在那年，人类来到这座岛上。在毫不知情的情况下，他们的船只带来了大大小小的老鼠。这些小动物很快占领了这座岛屿，吃鸟蛋并攻击雏鸟。猫被带到这座岛上来控制这些大大小小的老鼠。不幸的是，这些猫随后也对鸟类产生了兴趣。
与此同时，作为人类的食物来源，兔子被引进到这座岛上。它们(兔子)在岛上逍遥自在，做了最擅长做的事——它们迅速繁殖，开始吃当地的植物并且挖洞，造成了水土流失。兔子数量的迅猛增长为猫提供了充足的食物，这意味着猫的数量也增加了。相应地这导致更多的猫捕食鸟类。最终的结果是，岛上原本数量众多的本土鸟类——长尾鹦鹉，在1891年灭绝了。
甚至在20世纪70年代，麦夸里岛成为官方认定的自然保护区后，兔子仍然无法控制。专家们认为，必须找到一个方案使所有的兔子都从岛上消失。怀着这个目标，他们在岛上投放了一种病毒。虽然该病毒导致兔子的数量从13万只减少到1万只左右，但这也意味着猫的食物减少了。结果这些猫把它们的注意力——以及它们的胃口——转回到当地的鸟类身上，它们每年杀死的鸟多达6万只。20世纪80年代，陷阱和狗被用来抓猫。麦夸里岛上的最后一只猫在2000年被捕获。
不过，俗话说：“猫儿不在，老鼠翻天。”随着岛上猫的离开，大小老鼠的数量开始上升。还记得那一万只左右的兔子吗？结果这些兔子对病毒产生了免疫力，它们的数量再次激增。然后，在2006年，兔子挖洞导致一些土地坍塌，使得大量的企鹅丧生。这一事件清楚地表明，大小老鼠和兔子的问题需要得到彻底解决。
因此，我来到麦夸里岛，正是参加解决这一问题的项目。第一步涉及用直升机投放毒药。接下来的一步是清除最后残存的入侵物种。那就是我带着我的狗涉入的阶段。这些狗受过训练，能在不伤害岛上本土动物的前提下，找到所有剩余的入侵物种。这样的干预为这个悲剧故事画上一个长长的、迟来的句号，而这是我们人类应该为这座岛所做的事情——给它一个美好的结局。
附言：2014年，麦夸里岛被宣布为非兽害区，并且岛上的生态终于走上了复苏之路。
