考研網(wǎng)校復(fù)習(xí)專區(qū)英語閱讀二:生物與環(huán)境平衡的危機(jī)

　　The history of life on earth has been a history of interaction between living things and their surroundings. To a large extent,the physical form and the habits of the earths vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time,the opposite effect,in which life actually modifies its surroundings,has been relatively slight. Only in the present century has one species man acquired significant power to alter the nature of his world.

　　During the past quarter century this power has not only become increasingly great but it has changed in character. The most alarming of all mans assaults upon the environment is the contamination of air,earth,rivers,and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable. In this now universal contamination of the environment,chemicals are the sinister partners of radiation in changing the very nature of the world the very nature of its life. Chemicals sprayed on croplands or forests or gardens lie long in soil,entering into living organisms,passing from one to another in a chain of poisoning and death. Or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation,sicken cattle,and work unknown harm on those who drink from once pure wells. Man can hardly even recognize the devils of his own creation， as a scientist has said.

　　It took hundreds of millions of years to produce the life that now inhabits the earth. Given time not in years but in millennia life adjusts,and a balance has been reached. But in the modern world there is no time.

　　The rapidity of change follows the impetuous pace of man rather than the deliberate pace of nature. Radiation is now the unnatural creation of mans tampering with the atom. The chemicals are the synthetic creations of mans inventive mind,having no counterparts in nature.

　　To adjust to these chemicals would require not merely the years of a mans life but the life of generations. And even this,were it by some miracle possible,would be futile,for the new chemicals come from our laboratories in an endless stream; almost five hundred annually find their way into actual use in the United States alone. Among them are many that are used in mans war against nature. Since the mid 1940s over 200 basic chemicals have been created for use in killing insects,weeds,and other organisms described as pests.

　　譯文：

　　地球上生命的歷史一直就是一部生物與其環(huán)境相互作用的歷史。在很大程度上，地球上動植物的形態(tài)以及習(xí)性都是由外部環(huán)境所塑造的。考慮到地球上生命存在的整個(gè)時(shí)間，相反作用，即生命對其周圍環(huán)境的實(shí)際改變作用，卻相對很小。只有在當(dāng)前這個(gè)世紀(jì)(指20世紀(jì))才有一個(gè)物種人類，獲得了強(qiáng)大的力量，改變了其所生存的世界的自然狀態(tài)。

　　在過去的1/4世紀(jì)中，這種力量不僅日趨強(qiáng)大，而且其性質(zhì)也發(fā)生了變化。在人類破壞環(huán)境的種種行為中，最令人擔(dān)憂的是人類向大氣、土壤、河流以及海洋中排放危險(xiǎn)甚至致命物質(zhì)，而當(dāng)今這種污染在很大程度上是無法挽救的。在當(dāng)今這種對環(huán)境的普遍污染中，化學(xué)制品與輻射狼狽為奸，改變著地球的自然狀態(tài)，也就是改變著地球上生命的自然狀態(tài)。噴灑到農(nóng)田、森林或者花園里的化學(xué)物質(zhì)長期滯留于土壤中，滲入有機(jī)體內(nèi)，并彼此相傳，形成了一個(gè)中毒與死亡的鏈條。化學(xué)物質(zhì)還神秘地通過地下水傳遞，最終以新的形式出現(xiàn)并結(jié)合，使植物毒死，牲畜害病，并使飲用一度純凈的井水的人遭受了不明之害。正如一位科學(xué)家所言：人類甚至對自己創(chuàng)造的惡魔都不認(rèn)識。

　　地球歷經(jīng)了許多億年才創(chuàng)造了棲息其上的生命。經(jīng)過了一定時(shí)間不是以若干年計(jì)而是以若干千年計(jì)的時(shí)間生命開始適應(yīng)環(huán)境，并形成了一種與環(huán)境的平衡。但是在現(xiàn)代世界中，時(shí)間這一因素已經(jīng)沒有了。

　　環(huán)境改變的速度不再順從大自然從容不迫的節(jié)奏，而是順從人類急切匆匆的步伐。輻射是當(dāng)今人類通過支配原子而得到的一種非自然的創(chuàng)造物。化學(xué)制品則是人類有發(fā)明創(chuàng)造力的頭腦創(chuàng)造出來的合成物，在自然界本無相應(yīng)的東西。

　　為了適應(yīng)這些化學(xué)制品，人類需要付出的時(shí)間不會只是一個(gè)人一生的時(shí)間，而是幾代人的時(shí)間。而即使這樣，就算出現(xiàn)奇跡成為可能，這種適應(yīng)也是徒勞的，因?yàn)樾碌幕瘜W(xué)制品從我們的實(shí)驗(yàn)室中源源不斷地涌出。僅在美國，每年就有大約500種化學(xué)制品投入使用，其中許多是用于人類對自然的戰(zhàn)爭中。從20世紀(jì)40年代中期起，人類已經(jīng)創(chuàng)造了200多種基本化學(xué)制品用來消滅昆蟲、野草以及其他所謂的有害生物。

　　重點(diǎn)詞匯:

　　1、character(人的)品質(zhì)，性格;(事物的)性質(zhì)、特性;

　　例句：He has a changeable character.

　　他性格多變。

　　2、assault攻擊，襲擊

　　例句：They made a strong assault on the town.

　　他們猛烈攻擊這個(gè)鎮(zhèn)子。

　　3、spray浪花，水花，噴液

　　例句：Did you bring along some insect spray?

　　你帶來殺蟲劑了嗎?

　　4、impetuous性急的，魯莽的，

　　例句：It was impetuous of her to do that.

　　她竟做那種事，真是魯莽。

　　5、deliberate不慌不忙的，從容的

　　例句：He is delibertate in his speech.

　　他說話從容不迫。

　　4、5兩詞的詞義可從上下文中體會出來

　　The rapidity of change follows the impetuous pace of man rather than the deliberate pace of nature.

　　可見由than相連，必然是兩個(gè)反義詞。

　　6、futile無益的，無效的，無希望的

　　例句：His efforts to save the business were futile.
