Nor would they fail to imagine[1] how its native inhabitants⑧，including royal penguins，king penguins，and elephant seals，existed in perfect harmony with⑨ their natural habitat⑩ for thousands of years.[1]nor置于句首，句子用部分倒裝。But the island's more recent history tells a different story.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，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.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.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.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.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．[2][2]it作形式賓語，真正的賓語是后面的that從句。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.譯文參考麥夸里島：從混亂不堪到精心保護(hù)我正站在麥夸里島上，這里位于太平洋的西南部，澳大利亞和南極洲的中間。強(qiáng)風(fēng)和驚濤駭浪將海島塑成現(xiàn)在狹長的形狀。青草和光禿禿的巖石形成了鮮明的對比，使它具有一種野性和自然的美。這座島是聯(lián)合國教科文組織確立的世界遺產(chǎn)，游客們都認(rèn)為其名副其實。他們也不難想象出，數(shù)千年來，包括帝企鵝、王企鵝和象海豹在內(nèi)的當(dāng)?shù)貏游锸侨绾闻c其自然棲息地完美地和諧共存的。但是，這座島近些年的遭遇則是截然不同的故事。悲劇從人類1810年來到這座島嶼開始。他們不經(jīng)意間隨船帶來了大鼠和小鼠。這些小動物很快就占領(lǐng)了島嶼，它們吃鳥蛋并攻擊幼鳥。為控制鼠患，人們帶來了貓，不幸的是，貓后來也對鳥類產(chǎn)生了食欲。與此同時，人們把兔子引進(jìn)島上作為食物。在島上自由自在，它們盡其所能——迅速繁殖，開始吃當(dāng)?shù)氐闹脖徊⑼诙?/span>，造成水土流失。爆炸式增長的兔子數(shù)量給貓?zhí)峁┝顺渥愕氖澄?/span>，這意味著貓的數(shù)量也增加，相應(yīng)地就有更多貓捕食鳥類。最終結(jié)果是，曾經(jīng)數(shù)量眾多的當(dāng)?shù)匚锓N長尾小鸚鵡在1891年滅絕。甚至在20世紀(jì)70年代麥夸里島成為官方自然保護(hù)區(qū)后，兔子仍然不受控制。專家認(rèn)為，必須想辦法清除島上所有的兔子。懷著這個目標(biāo)，人們投放了一種病毒到島上。然而，雖然病毒使得兔子的數(shù)量從130 000只減少到約10 000只，但這也意味著貓的食物變少了。結(jié)果，這些貓把它們的注意力——以及它們的胃——轉(zhuǎn)回到本地的鳥類身上，每年捕殺的鳥多達(dá)6萬只。20世紀(jì)80年代，人們利用捕獵夾和狗來抓貓。2000年，麥夸里島上的最后一只貓被抓。但正如俗語所說，“山中無老虎，猴子稱大王”。貓從島上消失了，小鼠和大鼠的數(shù)量便開始增加。還記得那10 000只左右的兔子嗎？它們最終對病毒產(chǎn)生了免疫，數(shù)量又一次激增。隨后，在2006年，兔子挖的洞造成一些土地坍塌，導(dǎo)致大量企鵝死亡。這一事件表明，大鼠、老鼠、兔子問題需要一勞永逸地解決。所以，正是為了解決這一問題，我來到麥夸里島上參與一項行動。行動的第一步是利用了直升機(jī)向島上投放毒藥。下一步是清除最后殘存的入侵物種，這就是我的工作了——和我的狗一起。這些狗受訓(xùn)去尋找剩下的每一只老鼠和兔子，同時又不傷害當(dāng)?shù)貏游?。這次干預(yù)行動是這場悲劇漫長而屢被長久耽擱的結(jié)局，但我們?nèi)祟愑辛x務(wù)給這個島一個幸福的結(jié)局。附言：2014年，麥夸里島被宣布為非獸害區(qū)，并且島上的生態(tài)終于走上了復(fù)蘇之路。
