沙漠之舟艾尔•戈尔--------------------------------------------------------------------------------我头顶烈日站在一艘渔船的滚烫的钢甲板上。
这艘渔船在丰收季节一天所处理加工的鱼可达15吨。
但现在可不是丰收季节。
这艘渔船此时此刻停泊的地方虽说曾是整个中亚地区最大的渔业基地,但当我站在船头向远处眺望时,却看出渔业丰收的希望非常渺茫。
极目四顾,原先那种湛蓝色海涛轻拍船舷的景象已不复存在,取而代之的是茫茫的一片干燥灼热的沙漠。
渔船队的其他渔船也都搁浅在沙漠上,散见于陂陀起伏、绵延至天边的沙丘间。
十年前,咸海还是世界上第四大内陆湖泊,可与北美大湖区五大湖中的最大湖泊相媲美。
而今,由于兴建了一项考虑欠周的水利工程,原来注入此湖的水被引入沙漠灌溉棉田,咸海这座大湖的水面已渐渐变小,新形成的湖岸距离这些渔船永远停泊的位置差不多有40公里远。
与此同时,这儿附近的莫里那克镇上人们仍在生产鱼罐头,但所用的鱼已不是咸海所产,而是从一千多英里以外的太平洋渔业基地穿越西伯利亚运到这儿来的。
我因要对造成环境危机的原因进行调查而得以周游世界,考察和研究许多类似这样破坏生态环境的事例。
一九八八年深秋时节,我来到地球的最南端。
高耸的南极山脉中太阳在午夜穿过天空中的一个孔洞照射着地面,我站在令人难以置信的寒冷中,与一位科学家进行着一场谈话,内容是他正在挖掘的时间隧道。
这位科学家一撩开他的派克皮大衣,我便注意到他脸上因烈日的曝晒而皮肤皲裂,干裂的皮屑正一层层地剥落。
他一边讲话一边指给我看。
从我们脚下的冰川中挖出的一块岩心标本上的年层。
他将手指.到二十年前的冰层上,告诉我说,“这儿就是美国国会审议通过化空气法案的地方。
”这里虽处地球之顶端,距美国首都华盛顿两大洲之遥,但世界上任何一个国家只要将废气排放量减少一席在空气污染程度上引起的相应变化便能在南极这个地球上最偏而人迹难至的地方反映出来。

There are a few camels in Istanbul,but camels don’t belong in Europe. They have to be carried across the Bosporus from Asia, for a camel is said to be the only animal that cannot swim and cannot learn to swim. Most animals,like dogs,swim naturally; they don’t have to learn. The c amel may not be able to swim, but he can cross deserts, which no other animal can do as well.君士坦丁堡有很多骆驼,可是骆驼并不来自欧洲。
这种动物是人们从亚洲带过来的。
人们牵着骆驼,从陆上跨过博斯普鲁斯海峡,来到了这里。
因为据说骆驼是唯一不会游泳,也学不会游泳的动物。
大多数动物,例如狗,天生就会游泳,它们根本用不着学。
骆驼虽然不会游泳,但是它能够跨越沙漠,这是其他動物做不到的。
The camel is an animal of the desert, and when we see camels we know there must be deserts somewhere near. The camel loves heat and dryness, the sun and sand. Men and most animals,when it is hot, like the cool shade when they rest, but a camel when he rests, lies down in the hot sun. He is often called “the ship of the desert”,for he is the only “boat” that can carry passengers across the sea of sands. His feet are made like cushions so that they do not sink into the sand. A camel has several pouches inside of his body in which to store up water, as in tanks, for in crossing desert lands he may have to go days at a time without a drink, so he fills up these tanks inside of him.骆驼是沙漠动物。

沙漠之舟高级英语The Enigmatic Beauty of the DesertThe desert, with its vast expanse of barren land, often evokes images of desolation and harshness. However, beneath the seeminglylifeless and inhospitable surface lies a world of profound beauty and mystery. The desert, like an enigmatic boat sailing through time, hasits own unique allure that captivates the hearts and minds of those who dare to explore its secrets.First and foremost, the desert's breathtaking landscapes are a sight to behold. From the towering dunes of the Sahara to the rugged canyonsof the American Southwest, these natural wonders inspire a sense of awe and wonder. The shifting sands, sculpted by the wind over millennia, create ever-changing patterns that mesmerize the eyes. The play of light and shadow on the dunes at sunrise or sunset is a spectacle that canonly be witnessed in the desert. It is a reminder that even in the harshest of environments, nature can create moments of transcendent beauty.Moreover, the desert is a haven for unique and resilient forms of life. Despite the scarcity of water and extreme temperatures, flora and fauna have adapted to survive and thrive in these challenging conditions. The Joshua trees of California's Mojave Desert and the cacti of the Sonoran Desert are testament to nature's ingenuity. Their ability to store water and endure prolonged periods of drought is a testament tothe resilience of life.The desert also holds a wealth of cultural and historical significance. For centuries, nomadic tribes and ancient civilizations have called the desert home. These cultures have developed intricate systems of survival and thrived in harmony with their environment. From the Bedouin tribes of the Arabian Desert to the Native American tribesof the Southwest, the desert has shaped their way of life, their customs, and their traditions. Their stories and legends, passed down from generation to generation, add to the mystique and allure of the desert.In addition to its natural and cultural wonders, the desert offers a unique sense of solitude and introspection. The vastness of the landscape and the absence of human presence allow for a deeperconnection with oneself and the universe. The silence of the desert is a stark contrast to the noise and chaos of modern life. It offers a sanctuary for reflection and contemplation, a space to escape from the distractions of the world and find inner peace.However, it is important to acknowledge the fragility of the desert ecosystem and the need for its conservation. Human activities, such as overgrazing, urbanization, and climate change, pose significant threats to the delicate balance of desert ecosystems. Efforts must be made to protect these unique and invaluable landscapes for future generations to enjoy and appreciate.In conclusion, the desert is far from a barren wasteland. It is a place of wonder and beauty, a testament to the resilience of life andthe ingenuity of nature. From its breathtaking landscapes to its rich cultural heritage, the desert offers a wealth of experiences andinsights for those willing to embark on a journey of exploration. It isa reminder that even in the harshest of environments, there is beauty to be found.。
Ships in the Desert沙漠之舟There is only one precedent for this kind of challenge to our thinking, and again it is military. The invention of nuclear weapons and the subsequent development by the Unit-ed States and the Soviet Union of many thousands of strategic nuclear weapons forced a slow and painful recognition that the new power thus acquired forever changed not only the relationship between the two superpowers but also the relationship of humankind to the institution at war-fare itself. The consequences of all-out war between nations armed with nuclear weapons suddenly included the possibility of the destruction of both nations – completely and simultaneously. That sobering realization led to a careful reassessment of every aspect of our mutual relationship to the prospect of such a war. As early as 1946 one strategist concluded that strategic bombing with missiles "may well tear away the veil of illusion that has so long obscured the reality of the change in warfare –from a fight to a process of destruction.”对我们的思维方式提出这种挑战性要求的先例只有一个,而这一先例又是来自军事方面的。
Lesson SevenThe Libido for the Ugly-- H.L. MenckenPre-reading questions⏹Do you like beautiful things or ugly things? What’s your concept of beauty?⏹Have you ever seen or heard anyone who loves ugly things? Do you think them normal? What makes them do so?⏹What is libido?⏹What impresses you most after you have read the lesson?⏹Who is the writer of this lesson? Give a brief introduction to the writer and his writing style.BackgroundHenry Louis Mencken (1880-1956)American educator, author, criticH. L. Mencken is an American literary critic, humorous journalist, essayist, whose comic skepticism about human progress, expressed with penetrating style, is a treasure for all interested in extravagant language. Mencken wrote - according to some estimations –3, 000 newspaper columns. During the 15-year period following World War I, Mencken set the standard for satire in his day, and his essays are still widely read.Background⏹His life⏹He was born and spent most of his life in the city of Baltimore, Maryland. He was the son of German immigrant parents. He completed high school but did not attend university, only graduated from Baltimore Polytechnic Institute at 16. He became a reporter on the Baltimore Morning Herald. 《先驱报》Background⏹A few years later, he joined the staff of its rival newspaper, the Baltimore Sun or Evening Sun, first as a reporter, then as its drama critic and editor, a position which he held until 1941.⏹He helped to found and edit two literary magazines which were highly influential among intellectuals.1) The Smart Set《时髦者》2) The American Mercury门肯和内森在1924年创办了《美国水星》杂志Background⏹Mencken was one of the most influential American critics in the 1920s. He helped such newcomers as Theodore Dreiser and Sinclair Lewis. As an editor he published manuscripts by such young writers as Eugene O'Neill and Dorothy Parker. He reviewed major works of Upton Sinclair, Henry James and F. Scott Fitzgerald, whose first published story appeared in the Smart Set.Background⏹He was a central figure in American intellectual life during the 1920's. He contributed to Chicago Tribune 论坛报(1924-28), New York American(1934-35), and the Nation(1931-32). He was a columnist in Evening Mail in New York (1917-18), and 'The Free Lance' in Sunpapers (1919-41) in Baltimore.Background⏹He launched the most cutting attacks of any writer against America's middle class culture. He invented the word "booboisie―, combining the two words "bourgeoisie" and "booby" (an awkward, foolish person).Background⏹In his witty essays, he derided (mock) the institution which supported the middle class. He enjoyed controversy and tried to arouse his antagonists with his direct and devastating attacks: Background1) He hated narrow-minded religion. He believed strongly in intellectual freedom and fought all attempts to censor审查literature and drama. He felt that the greatest threat of censorship came from the country's religion "fundamentalists", whose opinions were all based on their interpretation of the Bible.BackgroundE.g.⏹―H. L. Mencken wrote sulphurous dispatches sitting in his pants with a fan blowing on him, and there was talk of running him out of town for referring to the local citizenry as yokels.‖ Background2) He hated commercialism.3) He did not support democracy because he considered the masses too ignorant and greedy to exercise it wisely.Background⏹Mencken's essays were received with delight or horror, depending on the reader's point of view, he was also highly respected for his literary criticism and he exerted a powerful influence on American literature.Background⏹He was a leading scholar in the field of language. His monumental book The American Language is considered an outstanding work of philology.⏹He made a large contribution to the study of language and particularly encouraged scholarly study of the American branch of English.The American LanguageA guide to American expressions and idioms, which was a critical and popular success.a) It examined the development of the English language in America.b) It contrasted English and American expressions and usage.c) It explained the origin of many American idioms.d) It traced the influence of immigrant languages on American English.Background⏹His Style⏹He is well-known for his bombastic style and acid tongue.⏹He wrote with verve ( 活力), gusto ( 热忱) and exaggeration. His exuberant ( 过于华丽)and extravagant use of the language was so amusing and startling that even his most violently critical essays became acceptable to his readers.Background⏹He employed a huge vocabulary and liked to insert unusual or unexpected words, for surprise or comic effect, into otherwise normal sentences. Although his style is occasionally difficult to read, Mencken is still considered one of the best and liveliest essayists of this century.Background⏹His works⏹The American Language1918⏹Prejudices (6 vols) 1919--1927⏹Happy days⏹Newspaper Days1940 –1943 autobiographical⏹Heathen Days trilogy⏹25 Books and thousands of articlesText study⏹What type of writing is this lesson?-- Descriptive writing.Text study⏹Descriptive writing⏹Language points⏹Comprehension Questions⏹Text Analysis and AppreciationDescription⏹Descriptive writing is an art form.

1.我头顶烈日站在一艘渔船的滚烫的钢甲板上。
这艘渔船在丰收季节一天所处理加工的鱼可达15吨。
但现在可不是丰收季节。
这艘渔船此时此刻停泊的地方虽说曾是整个中亚地区最大的渔业基地,但当我站在船头向远处眺望时,却看出渔业丰收的希望非常渺茫。
极目四顾,原先那种湛蓝色海涛轻拍船舷的景象已不复存在,取而代之的是茫茫的一片干燥灼热的沙漠。
渔船队的其他渔船也都搁浅在沙漠上,散见于陂陀起伏、绵延至天边的沙丘间。
十年前,咸海还是世界上第四大内陆湖泊,可与北美大湖区五大湖中的最大湖泊相媲美。
而今,由于兴建了一项考虑欠周的水利工程,原来注入此湖的水被引入沙漠灌溉棉田,咸海这座大湖的水面已渐渐变小,新形成的湖岸距离这些渔船永远停泊的位置差不多有40公里远。
与此同时,这儿附近的莫里那克镇上人们仍在生产鱼罐头,但所用的鱼已不是咸海所产,而是从一千多英里以外的太平洋渔业基地穿越西伯利亚运到这儿来的。
2.我因要对造成环境危机的原因进行调查而得以周游世界,考察和研究许多类似这样破坏生态环境的事例。
一九八八年深秋时节,我来到地球的最南端。
高耸的南极山脉中太阳在午夜穿过天空中的一个孔洞照射着地面,我站在令人难以置信的寒冷中,与一位科学家进行着一场谈话,内容是他正在挖掘的时间隧道。
这位科学家一撩开他的派克皮大衣,我便注意到他脸上因烈日的曝晒而皮肤皲裂,干裂的皮屑正一层层地剥落。
他一边讲话一边指给我看。
从我们脚下的冰川中挖出的一块岩心标本上的年层。
他将手指.到二十年前的冰层上,告诉我说,“这儿就是美国国会审议通过化空气法案的地方。
”这里虽处地球之顶端,距美国首都华盛顿两大洲之遥,但世界上任何一个国家只要将废气排放量减少一席在空气污染程度上引起的相应变化便能在南极这个地球上最偏而人迹难至的地方反映出来。
3.迄今为止,地球大气层最重要的变化始于上世纪初的工业命,变化速度自那以后逐渐加快。
工业意味着先是煤、后是石油消耗。
我们燃烧了大量的煤和石油——导致大气层二氧化碳含的增加,这就使更多的热量得以留存在大气层中,从而使地球的候逐渐变暖。
离南极极点不到一百码远,在雪上飞机降落的冰铺道上风处,科学家们一日数次地测量大气,以便绘制图表记录下无情的变化。
雪上飞机在冰铺跑道上降落后,引擎仍得保持运聋以防金属部件冻住而无法发动。
在我访问期间,我观看了一位科家绘出那天的测量结果,把图表上一条斜度很大的上升的线再上推进。
他告诉我——在这地球的尽头——很容易看清全球大层的巨大变化的速度仍在加快。
4.两年半以后,在地球的另一端,在寒冷至极的北冰洋上漂浮的一块十二英尺厚的冰板上搭起的小帐篷里我又体验到了在午的阳光下睡觉的滋味。
饱吃了一顿早餐后,我和同伴们一起乘雪防滑汽车北行数英里,到了约定会合地点,那儿的冰层较薄——有三英尺半厚——水下有一艘核潜艇在那儿徘徊着。
潜艇破冰上来,载上新的乘客后又潜了下去。
我也就开始同那些正设法以高的精确度测量极地冰帽厚度的科学家们进行交谈。
许多人认北极冰层由于地球气候的转暖而正在变薄。
此前我刚刚通过谈使美国海军方面与研究北极冰层的科学家达成协议,向他们提由水下声纳系统探测得到的本来属于最高机密的有关资料,这资料有助于他们了解北极冰层所发生的情况。
现在我想实地考一下北极极点。
我们登上潜艇约八个小时后,潜艇冲破冰层浮上面。
于是,我便置身于一片神奇瑰丽的冰雪世界中。
雪原上寒风劲扫,银光闪耀,其边缘则是一道由连绵起伏的小冰丘或由冰席相撞、相互挤压而形成小型山脉的冰层“压脊”勾勒出的地平线。
但即使在这儿,空气中二氧化碳的含量也在不断上升,最后气温也必然会随之上升——事实上,地球气候变暖会使南北极地区在气温上升的速度上远高于世界的其他地区。
随着极地气温的升高,这里的冰层会融化变薄。
由于南北极的冰帽对全球的气候有着至关重要的调节作用,它们的融化将会带来灾难性的后果。
5.探索这些问题并不是一种纯理论性的工作。
我从北极回来后过了六个月,就有一队科学家报称北极冰层的分布结构已发生显著变化;另一队科学家则在考察报告中提出了一个更有争议的说法(如今已有大量资料可以佐证):总体说来,仅在过去十年当中,北极冰层已融化了百分之二。
另外,科学家们还在几年前就已证实,在北极圈以北的许多地区,春季雪融的时间逐年提前,而且冻土带的地下深处的温度都在稳步上升。
6.凑巧的是,破坏生态环境的一些最典型的、最令人担忧的事例刚好都发生在南北极正中间的地方——巴西境内的赤道带上——那儿滚滚浓烟时常弥漫着辽阔但现又面临着破坏的亚马孙热带雨林的上空。
亚马孙雨林正被人们大片大片地烧毁,以便腾出空地作饲养速食肉牛的牧场。
我1989年初去那儿时得知,现在旱季时节放火焚烧森林的时间正逐年提前,其结果是每年都有面积比整个田纳西州还大的大片森林遭到砍伐焚烧。
据给我们当向导的生物学家汤姆•洛夫乔伊介绍,亚马孙雨林中每平方英里的林区栖息的禽鸟种类多于整个北美洲现存的禽鸟种类——这就意味着我们正在使成千上万种我们从来没有听到过的飞禽的歌声永远消失。
7.人们也不一定非要周游世界才能目睹人类对地球的破坏。
今天的世界上,预示着地球生态危机的景象已是随处可见。
在北方高纬度地区,夜晚的天空有时也会呈现出另一种预示地球上日趋严重的生态失衡的阴森景象。
假如日落后天空明朗无云——而且你又置身于一个空气污染还没有严重到足以完全遮蔽夜空的地方进行观察的话——你会看见天空高处有时会出现一种奇异的云团。
这种“夜光云团”偶尔出现于夜幕开始笼罩大地的时候,它呈半透明的白色,在高空中闪烁发光,看起来颇不像自然之物。
其实,这种云团也确非自然之物:近年来由于大气中甲烷含量的大幅度增高,夜光云团的出现频率也随着上升了。
(甲烷又称天然气,它产生于填土、煤矿、糠壳、新砍伐的林地里群聚的白蚁、燃烧生物以及人类许多其他的活动过程中。
)虽说过去天空偶尔也出现过夜光云团,但大气层中所含的那些过量的甲烷会将更多的水蒸气带到高层大气中;水蒸气在更高处凝结,会形成更厚的云层,夜幕降临以后很久,这些位于高空的云层下方还在受着太阳光的照射。
8.对天空中出现的这些奇异现象我们应当如何看待呢?是仅仅叹为奇观还是怀着像我们在动物园中观看动物时感受到的那种复杂的感情?也许我们应当为自己所具有的破坏力而惊奇赞叹:正如人类由于大量猎取象牙致使大象面临灭种威胁一样,我们今天正由于大量糟蹋和破坏地球上的自然资源而使白天和黑夜之间的平衡遭到破坏。
我们的这种行为更进一步地增加了地球变暖的危险,因为甲烷是一种形成速度极快韵温室效应气体,它在大气中的总含量仅次于二氧化碳和水蒸气,使高空大气层的化学成分都发生了变化。
即使不去考虑这种危险,但只要意识到我们让这些闪烁着阴森森的鬼火般光亮的云团笼罩着自己头顶上的夜空,这还不就足以令我们警醒吗?难道说是我们的眼睛因为过分习惯于人类文明之光而对这些云团视而不见——看不出它们乃是人类文明同地球之间的激烈冲突的一种具体表现形式吗?9.尽管有时很难理解其真正含义,我们大家都曾耳闻目睹过一些反映人类对生态环境造成破坏的惊人的现象——或是气温超过一百度的高温天气出现频率的增加,或是太阳灼伤人的皮肤的速度的加快,或是公众对越积越多的废物该如何处理这一问题进行讨论的热情的高涨。
但是,我们大家对这些现象所作的反应却很有点奇怪。
我们为何不采取切实有效的行动来保护生态环境呢?这个问题也可以换一种方式来问:为什么有些现象会引起我们重视,促使我们立即采取行动,努力寻求有效对策?为什么另外一些现象,虽然有时也同样严重,却让人们无动于衷,人们的注意力不是集中在寻求积极有效的对策而是某种方便省事的规避策略呢?10.话说回来,由于令人担忧的生态环境受到破坏的现象太多了,使人有时确乎难以认识其实质意义和影响。
在对这些威胁生态环境的现象进行考察分析之前,下面的做法也许是有益的:对这些现象进行分级归类,从而使我们的思想感情条理化,以便根据实际情况采取相应的合理的对策。
11.有一套行之有效的分级归类方法源自于军队。
他们经常将冲突根据其发生范围的大小分为三级,即“局部性冲突”,“地区性战斗”,及“战略性对抗”。
第三级指的是直接威胁到一个国家的生存,因而必须以全球局势为背景来进行认识的军事对抗行为。
12.对生态环境方面的危机也可以这样来加以考虑。
比如,水域的污染、空气的污染和非法倾倒垃圾的行为多半属于局部性的问题,而诸如酸雨、地下含水层的污染以及大面积的石油泄漏一类的问题则基本上是地区性的。
这两类问题都带有普遍性,世界各地可能同时出现性质相同的局部性问题和地区性问题,因此,这些局部性问题和地区性问题又似乎可以看作是全球性的问题。
但它们并不属于战略性问题,因为这些问题并没有对全球生态环境的本质结构造成影响,也没有直接威胁到人类社会的生存。
13.然而,新的一类环境问题确实影响全球生态系统,而这些威胁基本上是战略性的。
过去四十年中大气层氯的含量增加了百分之六百,这不仅发生在那些生产与此直接相关的氟里昂的国家,而且发生在所有国家的上空,还同样发生在南极上空、北极上空和太平洋上空——从地球表面一直到天空深处。
氯含量的增加破坏了地球调节太阳通过大气层射到地面的紫外线辐射量的全球程序。
如果我们让氯含量继续增加,那么紫外线辐射量也将增加——终有一天会威胁到所有的动植物的生存。
14.地球气候转暖也是一种战略性威胁。
自第二次世界大战以来,大气层中二氧化碳和其他一些吸热物质分子的含量已增加了近百分之二十五,这便对地球自身具有的调节太阳热量在大气层中存留量的能力构成了世界性的威胁。
由此导致的大气层中热量的增高会严重破坏地球的气候平衡机制,从而影响到地球上的风量、雨量、地面温度、洋流和海面高度,而正是这些因素反过来又决定着陆地和海上动植物的生态分布,也在很大程度上决定着人类社会的定居地点和生活方式。
15.换句话说,由于人类社会已突然具备了改变整个地球而不只是某一特定地区的生态环境的能力,人类与地球之间的关系便整个地发生了改变。
众所周知,人类文明对地球上的环境一贯有着极大的影响。
且举一例来说明吧:还在远古时代,人类为了觅食求生,有时便纵火焚毁大片原始森林,这是有据可考的。
而在今天我们这个时代,人类已经把地球表面的很大一部分完全改换了面貌,城镇里的地面换成了混凝土,乡村里的地面则改造成了精心培育的稻田、牧场、麦田和其他农作物种植地。
人类加于地球上的这类改变,有时虽然似乎有着深远的影响,但它们对全球生态系统直到最近仍只产生着微不足道的影响。
在我们这个时代以前,的确可以高枕无忧地认为,无论是人类所曾做过的或是所能做的任何事情,都不可能对地球上的环境产生永久性的影响。
但是今天,我们却必须抛弃这种想当然的想法,这样才能够以战略性眼光来考虑并重新认识我们人类同地球环境之间的关系。
