MACQUARIE ISLAND:from Chaos to Conservation
I am standing on Macquarie Island, in the South-west Pacific Ocean, halfway between Australia and Antarctica. Strong winds and stormy seas have helped sculpt its long, thin shape. The green grass and bare rock of its landscape contrast dramatically, giving it a wild and natural beauty.(1) No visitor would think it surprising that the island is a UNESCO World Heritage Site.(2) Nor would they fail to imagine how its native inhabitants, including royal penguins,king penguins,and elephant seals, existed in perfect harmony with their natural habitat for thousands of years.(3)
麦夸里岛:从混乱到保护
我正站在麦夸里岛上,该岛在太平洋西南部,位于澳大利亚和南极洲的中间。强风和惊涛骇浪将海岛塑造成了狭长的形状。绿色的草地和裸露的岩石形成的景观反差巨大,赋予它一种野性和天然的美。该岛是联合国教科文组织评定的世界遗产,游客们都认为它名副其实。他们也不难想象出,包括皇家企鹅、王企鹅和象海豹在内的当地动物数千年来是如何与其自然栖息地和谐共存的。
【助读点拨】
(1)句中giving it a wild and natural beauty作结果状语。
(2)句中it作形式宾语,真正的宾语是that引导的从句。
(3)本句是以否定词开头的倒装句,nor置于句首,would需提前。
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.(4) 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.
但是,这座岛近些年的遭遇则讲述了一个截然不同的故事。悲剧始于1810年人类来到这座岛上。他们无意中把老鼠带上了船。这些小动物很快占领了这个岛,它们吃鸟蛋并攻击幼鸟。为控制鼠患,猫被带到岛上。不幸的是,猫后来也开始以鸟为食。
与此同时,兔子被引进岛上作为人类食物的来源。由于兔子在岛上自由自在,它们尽其所能——迅速繁殖,开始吃当地的植被并挖洞,造成了水土流失。数量激增的兔子为猫提供了充足的食物,这意味着猫的数量也在增加。这反过来又导致更多的猫捕食鸟类。最终的结果是,曾经数量众多的当地物种长尾鹦鹉于1891年灭绝。
【助读点拨】
(4)句中which引导非限制性定语从句。
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.(5) 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.(6) In the 1980s, traps and dogs were used to catch the cats. The last Macquarie Island cat was caught in 2000.
即使在20世纪70年代麦夸里岛成为官方自然保护区后,兔子仍然不受控制。专家们认为有必要想出一个计划,清除岛上所有的兔子。怀着这个目标,人们投放了一种病毒到岛上。然而,虽然病毒使兔子的数量从13万只减少到1万只左右,但是这也意味着猫的食物减少了。结果,这些猫把注意力——还有它们的胃口——重新转移到了当地的鸟类身上, 它们每年捕杀的鸟多达6万只。20世纪80年代,人们用捕猎夹和狗来捕猫。麦夸里岛上最后一只猫是在2000年被抓住的。
【助读点拨】
(5)句中it作形式宾语,真正的宾语是后面的动词不定式短语。
(6)句中killing up to 60,000是动词-ing形式作结果状语。
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)
但正如俗话所说:“猫儿不在,老鼠作怪。”随着猫从岛上消失,老鼠的数量便开始增加。还记得那1万只左右的兔子吗 结果表明它们对病毒产生了免疫力,兔子的数量再次激增。随后,在2006年,兔子的挖掘导致一些土地塌陷,大量企鹅死亡。这一事件清楚地表明,鼠兔问题需要彻底解决。
【助读点拨】
(7)句中it作形式宾语,指代后面的宾语从句 that the rat, mouse and rabbit problem needed solving once and for all.
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.
所以,正是为了解决这个问题,我来到麦夸里岛,参与一项行动。行动的第一步是从直升机上投放毒药。下一步是要清除最后残存的入侵物种,这就是我的工作——带着我的狗一起。它们受训在不伤害当地动物的情况下,找到剩下的每一只老鼠和兔子。这次干预行动是这场悲剧漫长而几经拖延的大结局,但这是我们人类应该做的,我们欠这座岛屿一个美好的结局。
