每日一練|考研英語(yǔ)一翻譯篇真題練習(xí)（二）

　　01

　　When one of these noneconomic categories is threatened and,if we happen to love it.We invert excuses to give it economic importance.At the beginning of century songbirds were supposed to be disappearing.(46)Scientists jumped to the rescue with some distinctly shaky evidence to the effect that insects would eat us up if birds failed to control them.The evidence had to be economic in order to be valid.

　　譯：

　　當(dāng)某一類(lèi)沒(méi)有經(jīng)濟(jì)價(jià)值的物種受到威脅，而我們又恰巧喜歡這類(lèi)物種時(shí)，我們就會(huì)編造一些借口來(lái)賦予它經(jīng)濟(jì)重要性。在本世紀(jì)初，鳴禽原本就要消失了。(46)科學(xué)家們急忙挽救，但提出的證據(jù)非常站不住腳，這些證據(jù)的大意是:如果鳥(niǎo)類(lèi)不能控制昆蟲(chóng)的數(shù)量，昆蟲(chóng)便會(huì)吞噬我們?nèi)祟?lèi)。證據(jù)必須有經(jīng)濟(jì)價(jià)值才會(huì)有效。

　　02

　　A parallel situation exists in respect of predatory mammals and fish-eating birds.(48)Time was when biologists somewhat overworked the evidence that these creatures preserve the health of game by killing the physically weak,or that they prey only on“worthless”species.Here again,the evidence had to be economic in order to be valid.It is only in recent years that we hear the more honest argument that predators are members of the community,and that no special interest has the right to exterminate them for the sake of a benefit,real or fancied,to itself.

　　譯：

　　食肉哺乳動(dòng)物和食魚(yú)鳥(niǎo)類(lèi)也存在類(lèi)似的情形。(48)曾經(jīng)有段時(shí)間，生物學(xué)家有點(diǎn)濫用了這樣一種證據(jù)，即這些生物通過(guò)殺死體弱者，或者僅僅捕食“沒(méi)有價(jià)值的”物種，來(lái)保持獵物種群的健康。這再次說(shuō)明證據(jù)必須有經(jīng)濟(jì)價(jià)值才會(huì)有效。直到最近幾年，我們才聽(tīng)到更為誠(chéng)實(shí)的論點(diǎn):食肉動(dòng)物是這個(gè)群落的成員，沒(méi)有任何特殊利益群體有權(quán)為了自己的利益而消滅它們，無(wú)論這種利益是真實(shí)的還是假想的。

　　03

　　To sum up:a system of conservation based solely on economic self-interest is hopelessly lopsided.(50)It tends to ignore,and thus eventually to eliminate,many elements in the land community that lack commercial value,but that are essential to its healthy functioning.It assumes,falsely,I think,that the economic parts of the biotic clock will function without the uneconomic parts.

　　總而言之，一個(gè)只基于經(jīng)濟(jì)利己主義的保護(hù)系統(tǒng)是完全失衡的。(50)這種保護(hù)系統(tǒng)往往忽視了地群落中諸多缺乏商業(yè)價(jià)值，但對(duì)其健康運(yùn)行至關(guān)重要的物種，從而最終導(dǎo)致它們的滅絕。我認(rèn)為，它錯(cuò)誤地認(rèn)為在沒(méi)有無(wú)經(jīng)濟(jì)價(jià)值的部分的情況下，生態(tài)系統(tǒng)有經(jīng)濟(jì)價(jià)值的部分依然可以正常運(yùn)行。
