ThornleyThere are three main groups of oil:animal, vegetable and mineral. Great quantities of animal oil come from whales, those enormous creatures of the sea which are the largest remain

2、ing animals in the world. To protect the whale from the cold of the Arctic seas, nature has provided it with a tick covering of fat called blubber. When the whale is killed, the blubber is stripped off and boiled down, either on board ship or on shore. It produces a great quantity of oil which can b

Both cod liver oil and halibut liver oil are given to sick children and other invalids who need certain vitamins. Th

Perfumes may be made from the oils of certain flowers. Socpa are made from vegetable and animal oils.To the ordinary man, one kind of oil may be as impor

But when the politician or the engineer refers to oil, he almost always means mineral oil, the oil that drives tanks, aeroplanes and warships, motor-cars and diesel locomotivs, the oil that is used to lubricate all kinds of machinery. This is the oil that is used to lubricate all kn

To it we owe the existence of the motor-car, which has replaced the private carriage drawn by the horse. To it we owe the possibility of f

7、lying. It has changed the horse. To it we owe the possiblility of flying. It has changed the methods of warfare on land and sea. This knid of oil comes out of the earth. Because it burns well, it is used as fuel and in some ways it is superior to coal in this repect. Many big ships now burn oil inst

8、ead of coal. Because it burns brightly, it is used for illumination; countless homes are still illuminated with oil-burning lamps. Because it is very slippery, it is used for lubrication. Two metal surfaces rubbing together cause friction and heat; but if they are separated by a thin film of oil, th

9、e friction and heat are reduced. No machine would work for long if it were not properly lubricated. The oil used for this purpose must be of the correct thickness; if it is too thin it will not give sufficient lubrication, and if it is too thick it will not reach all parts that must e lubricated.(fr

10、om English Through Reading)參考譯文：G.C.索恩利油可以分為三大類：動(dòng)物油、植物油、礦物油。大量的動(dòng)物油是從鯨魚身上得來的。鯨魚是海里的龐然大物，是世界上現(xiàn)有動(dòng)物中最大的一種。大自然為了保護(hù)鯨魚，使它不不致在北冰洋受凍，便讓它長了厚厚的一層脂肪，叫做鯨脂。鯨魚殺死之后，把鯨脂剝下來熬油，這項(xiàng)工作有的是在船上進(jìn)行的，有的是在岸上進(jìn)行的。這樣，就能生產(chǎn)出大量的油，供人們食用。有些動(dòng)物也出油，但都沒有鯨魚出得多。鱈魚和比目魚，這兩種魚的肝臟出的油營養(yǎng)豐富。從這兩種魚得來的魚肝油可以給缺少某種維生素的患兒或其他病人服用。 這兩種魚肝油在任何一家藥房里都可以買到。植物油自古以

But unlike the roads in Robert Frosts familiar poem, they are not equall

23、on, Silent Spring)參考譯文：新路（摘錄1）雷切爾卡森我們正處于兩條道路分岔的地方。但是并不像我們所熟習(xí)的羅伯特弗羅斯特詩中所說的，這兩條路是同樣的好。我們一直在走的這條跌表面上很好走，是一條平坦的超級(jí)公路，我們可以高速前進(jìn)，但是走到盡頭地要遇到災(zāi)難。另外一條路，是一條“走得不多”的路，它為我們提供最后的出路，也是唯一的出路，以便我們達(dá)到一定的目的，使我們這個(gè)地球確實(shí)得到保護(hù)。走哪一條路，最終還是要由我們來選擇。如果我們?cè)谌淌芰撕荛L時(shí)間之后，終于提出了“知情權(quán)”，如果我們知情以后，認(rèn)為現(xiàn)在人們是在要求我們冒無謂的可怕風(fēng)險(xiǎn)，我們就不應(yīng)該再聽從那些人的建議，非得把我們這個(gè)世界弄得到

24、處都是化學(xué)毒物，而應(yīng)該往四下里看一看還有沒有什么別的路。除了用化學(xué)方法控制昆蟲以外，還有其他各種非常奇妙的方法可以利用。這些方法，有的已在使用，而且取得了顯著的效果。有的處于試驗(yàn)階段。有的則不過是富于想像力的科學(xué)家頭腦里的一些想法，等到有機(jī)會(huì)的時(shí)候才能加以試驗(yàn)。所有這些方法都有一個(gè)共同點(diǎn)：他們都是生物的解決辦法，其基礎(chǔ)是人們對(duì)所要控制的生物體的了解，以及對(duì)這些生物體整個(gè)生活狀況的了解。廣博的生物學(xué)各個(gè)領(lǐng)域的學(xué)家，包括昆蟲學(xué)家、病理學(xué)家、遺傳學(xué)家、生理學(xué)家、生物人學(xué)家、生態(tài)學(xué)家，都在做出貢獻(xiàn)，他們把自己的知識(shí)和創(chuàng)造性匯聚起來，形成了一門新的科學(xué)生物控制學(xué)。霍普金斯大學(xué)生物學(xué)家卡爾P斯旺森教授說：

25、“每一門科學(xué)都可以比做一條河。其源頭，隱隱約約，并不引人注目；其流勢(shì)，時(shí)而平緩，時(shí)而湍急；其水情，有汛期，也有枯竭期。由于許多人從事研究工作，各種思想像支流一樣注入其中，勢(shì)頭逐漸加強(qiáng)。新的概念和結(jié)論陸續(xù)產(chǎn)生，又使它得以加深和展寬。”現(xiàn)代的生物控制學(xué)就是如此。一百年前，這門科學(xué)在美國開始創(chuàng)立時(shí)也是隱隱約約的。當(dāng)時(shí)有些昆蟲給農(nóng)民找麻煩，有人就試圖以這些昆蟲的天敵來對(duì)付。這項(xiàng)活動(dòng)有時(shí)進(jìn)展緩慢，甚至毫無進(jìn)展，但有時(shí)一項(xiàng)突出的成就又推動(dòng)它加快速度，使它突飛猛進(jìn)。這門科學(xué)也有過枯竭期。在二十世紀(jì)四十年代，從事應(yīng)用昆蟲學(xué)的人看到新殺蟲劑的顯著效用，不禁為之眼花繚亂，便對(duì)生物方法冷眼相看，重新走上“化學(xué)控制的

26、老路”。然而實(shí)現(xiàn)無昆蟲的世界這一目標(biāo)卻越來越渺?！，F(xiàn)在已經(jīng)很明顯，盲目地大量使用化學(xué)殺蟲劑，對(duì)我們自己的威脅比對(duì)要控制的對(duì)象的威脅還要大，于是生物控制學(xué)這一條河又流動(dòng)起來，而且有新的思想支流注入其中。在這些新方法中，有一些最為令人神往，就是設(shè)法利用一種昆蟲本身的力量來對(duì)付這種昆蟲即利用昆蟲的生命力作為動(dòng)力來消滅之。這些方法之中，最引人注目的是“雄性不育”術(shù)，這種技術(shù)是由美國農(nóng)業(yè)部昆蟲研究所主任愛德華尼普林博士和他的同事們發(fā)明的。Lesson 24(CE)海洋可持續(xù)發(fā)展戰(zhàn)略中國有12億多人口，陸地自然資源人均占有量低于世界平均水平。根據(jù)中國有關(guān)方面的統(tǒng)計(jì)：中國有960萬平方公里的陸地國土，居世界
