每日一練|考研英語一翻譯篇真題練習(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：

　　當某一類沒有經(jīng)濟價值的物種受到威脅，而我們又恰巧喜歡這類物種時，我們就會編造一些借口來賦予它經(jīng)濟重要性。在本世紀初，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:如果鳥類不能控制昆蟲的數(shù)量，昆蟲便會吞噬我們?nèi)祟?。證據(jù)必須有經(jīng)濟價值才會有效。

　　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：

　　食肉哺乳動物和食魚鳥類也存在類似的情形。(48)曾經(jīng)有段時間，生物學(xué)家有點濫用了這樣一種證據(jù)，即這些生物通過殺死體弱者，或者僅僅捕食“沒有價值的”物種，來保持獵物種群的健康。這再次說明證據(jù)必須有經(jīng)濟價值才會有效。直到最近幾年，我們才聽到更為誠實的論點:食肉動物是這個群落的成員，沒有任何特殊利益群體有權(quán)為了自己的利益而消滅它們，無論這種利益是真實的還是假想的。

　　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，一個只基于經(jīng)濟利己主義的保護系統(tǒng)是完全失衡的。(50)這種保護系統(tǒng)往往忽視了地群落中諸多缺乏商業(yè)價值，但對其健康運行至關(guān)重要的物種，從而最終導(dǎo)致它們的滅絕。我認為，它錯誤地認為在沒有無經(jīng)濟價值的部分的情況下，生態(tài)系統(tǒng)有經(jīng)濟價值的部分依然可以正常運行。
