Unit 51

Nouabalé-Ndoki national park, in the Republic of Congo, is 4,200 square kilometres of virgin tropical forest that is as densely populated with elephants and great apes as it is sparsely populated with rangers. There are 14 of them, and they have failed to catch a single poacher for more than a year. That is not for lack of illegal hunting in the park. Demand for ivory is up, driven largely by consumers in Japan and an increasingly wealthy China. The value of meat from elephants, apes and other animals has also risen as loggers and miners move deeper into the country’s forests. Nor is this a problem confined to Congo. Last year poachers are estimated to have killed more than 23,000 African elephants. According to a study by the University of Washington, that is about one in 17 of the continent’s total.

Nouabalé-Ndoki’s rangers are, however, about to get some high-tech help in the form of TrailGuard, a system of small and easily hidden electronic detection and communication devices. They will soon begin burying radio-transmitting metal detectors alongside elephant trails leading into the park. Authorised travelers through the park will be given transponders that tell the detectors who they are, as with the “identification friend-or-foe” systems on military aircraft. But when poachers carrying rifles walk by a detector, it will send a radio signal to a treetop antenna. Seconds later the rangers will receive the intruder’s co-ordinates on their satellite phones. They will then be able to respond precisely, rather than running around on fruitless and demoralising patrols on the small chance of catching a poacher up to no good.

TrailGuard is the brainchild of Steve Gulick, an electrical engineer turned biologist who recently left the State University of New York（SUNY）to set up a not-for-profit organisation called Wildland Security, to promote his idea. Besides catching more（or, indeed, any）poachers, he hopes his invention will also prove to be an example of an idea from another one-time electrical engineer, Arthur C. Clarke. Clarke’s Third Law, as it is known to fans of his science-fiction writing, is that “any sufficiently advanced technology is indistinguishable from magic”. Many people in Congo do believe in magic and Mr. Gulick does not propose to disabuse them of the notion. Local people will receive no explanation for the rangers’ new powers. That, Mr. Gulick hopes, will discourage potential poachers from turning thought into deed.

Nor are metal detectors the only magic to be deployed. Small fire detectors hidden in trees should add to the anti-poaching unit’s reputation for detection. Poachers frequently smoke meat from their kills to preserve it during transport to market. Like the metal detectors, the fire detectors will alert the rangers by satellite phone, allowing them to swoop as from nowhere.

難句突破

TrailGuard is the brainchild of Steve Gulick, an electrical engineer turned biologist who recently left the State University of New York（SUNY）to set up a not-for-profit organisation called Wildland Security, to promote his idea.

主體句式：TrailGuard is the brainchild of Steve Gulick.

結(jié)構(gòu)分析：這個(gè)長(zhǎng)句看上去結(jié)構(gòu)復(fù)雜，其實(shí)其主句非常短，而后面部分都是Steve Gulick的同位語(yǔ)，用來補(bǔ)充說明Steve Gulick這個(gè)人物。同位語(yǔ)中包括了一個(gè)定語(yǔ)從句，而最后的不定式結(jié)構(gòu)是對(duì)前面“建立非營(yíng)利組織”的補(bǔ)充。

句子譯文：“行蹤警衛(wèi)”由史蒂夫·固利克發(fā)明。固利克先生從電子工程師轉(zhuǎn)行成為生物學(xué)家，他最近離開了美國(guó)紐約州立大學(xué)并創(chuàng)建了一個(gè)名為“野外安全”的非盈利組織，以推廣他的構(gòu)想。

題目分析

1. A 細(xì)節(jié)題。文章第一段提到偷獵并不是剛果一個(gè)國(guó)家的問題，可見這一問題存在于非洲的一些熱帶國(guó)家，是他們共有的問題。而B、C和D選項(xiàng)的表述均與第一段的文意相反。

2. B 情感態(tài)度題。本文作者自始至終都以非?？陀^的角度介紹“行蹤警衛(wèi)”技術(shù)，沒有加入個(gè)人的觀點(diǎn)，即使是對(duì)該技術(shù)一些成果的表述也不是作者自己的看法，而是引用事實(shí)或者他人的評(píng)價(jià)。

3. B 細(xì)節(jié)題。文章第三段指出固利克先生不會(huì)向本地人解釋這種科技產(chǎn)品的原理和能力，從而利用當(dāng)?shù)厝诵欧钅Хǖ男睦韥頊p少偷獵行為，由此可以推出當(dāng)?shù)厝藢?duì)這種未知的“魔力”會(huì)產(chǎn)生恐懼感。

4. A 細(xì)節(jié)題。文章第三段中指出固利克從亞瑟·克拉克那里學(xué)到的是讓人們以為科技是魔力的想法，而不是他的發(fā)明靈感，因此A選項(xiàng)的意思不正確。

5. B 推理題。文章第三段提到這項(xiàng)技術(shù)幾乎幫助抓獲了每一個(gè)偷獵者，因此是非常成功的。A選項(xiàng)的錯(cuò)誤原因在于，采用新技術(shù)之前護(hù)林員們抓獲偷獵者的幾率很低，但并不是完全抓不到。C選項(xiàng)的錯(cuò)誤原因在于偷獵者們熏肉主要是為了能夠長(zhǎng)時(shí)間地保存動(dòng)物尸體。D選項(xiàng)的錯(cuò)誤原因在于兩個(gè)人的背景對(duì)于“行蹤警衛(wèi)”的發(fā)明沒有直接影響。

參考譯文

位于剛果共和國(guó)的諾娃貝爾多基國(guó)家公園是一片面積達(dá)4200平方公里的熱帶雨林處女地，林中居住著大量大象和大猩猩，而護(hù)林員的數(shù)目卻相對(duì)非常少。14名護(hù)林員在過去的一年多時(shí)間內(nèi)沒有抓到一個(gè)偷獵者。這不是因?yàn)樯种型但C的人很少。在日本和越來越富有的中國(guó)，消費(fèi)者對(duì)于象牙的需求量很大，并且不斷上升。此外，隨著伐木工和礦工們不斷深入這個(gè)國(guó)家的森林，大象、猩猩和其他動(dòng)物的食用價(jià)值也變得越來越高。這個(gè)問題并不僅限于剛果。有數(shù)據(jù)顯示去年偷獵者們獵殺了23000多頭非洲象。華盛頓大學(xué)的一項(xiàng)調(diào)查表明，這個(gè)數(shù)字相當(dāng)于非洲大陸大象總數(shù)的1/17。

但是現(xiàn)在諾娃貝爾多基公園的護(hù)林員們將要開始使用一項(xiàng)名為“行蹤警衛(wèi)”的高科技手段，該系統(tǒng)是一個(gè)微型、易隱蔽的電子探測(cè)通訊工具。護(hù)林員們很快就會(huì)沿著大象通向國(guó)家公園的行蹤埋下傳播無(wú)線電的金屬探測(cè)器。經(jīng)過批準(zhǔn)的森林旅游者們可以領(lǐng)到一個(gè)脈沖轉(zhuǎn)發(fā)器，這個(gè)脈沖轉(zhuǎn)發(fā)器可以使探測(cè)器確認(rèn)旅游者的身份，就像戰(zhàn)機(jī)上配備的“敵友認(rèn)證”系統(tǒng)一樣。但是當(dāng)偷獵者們舉著步槍經(jīng)過探測(cè)器的時(shí)候，探測(cè)器就會(huì)向樹頂上的天線發(fā)出無(wú)線電信號(hào)。幾秒鐘后護(hù)林員們就可以通過衛(wèi)星電話收到入侵者們的坐標(biāo)。這樣他們就可以準(zhǔn)確地作出反應(yīng)，而不是盲目地在森林中進(jìn)行沒有成效且降低士氣的巡邏（因?yàn)橛眠@種方式抓到偷獵者的幾率非常?。?。

“行蹤警衛(wèi)”由史蒂夫·固利克發(fā)明。固利克先生從電子工程師轉(zhuǎn)行成為生物學(xué)家，他最近離開了美國(guó)紐約州立大學(xué)并創(chuàng)建了一個(gè)名為“野外安全”的非盈利組織，以推廣他的構(gòu)想。固利克先生除了通過該系統(tǒng)抓獲更多的（或?qū)嶋H上是每一個(gè)）非法偷獵者，他還希望他的發(fā)明能證明另一位曾經(jīng)擔(dān)任過電子工程師的名叫亞瑟·克拉克的人的想法?？死说摹暗谌▌t”是其科幻小說讀者都非常熟悉的，該法則指出“任何一種高科技都無(wú)法與魔法相區(qū)別”。許多剛果人都迷信魔法，而固利克先生并不打算破除他們的迷信。對(duì)于護(hù)林員的新能力，本地人不會(huì)得到任何解釋。固利克先生希望這樣能打擊潛在的偷獵者，使他們（在魔力的震懾下）不會(huì)把想法變?yōu)樾袆?dòng)。

金屬探測(cè)器并不是在林區(qū)使用的唯一魔法。隱藏在樹木中的小型火事探測(cè)器也增強(qiáng)了護(hù)林員的偵查能力。非法偷獵者經(jīng)常會(huì)在林區(qū)煙熏獵物，從而保證獵物在被運(yùn)送到市場(chǎng)的過程中不會(huì)變質(zhì)?；鹗绿綔y(cè)器與金屬探測(cè)器一樣，發(fā)送信號(hào)到護(hù)林軍的衛(wèi)星電話上，使他們能夠?qū)ν但C者們進(jìn)行突襲。
