科技英语阅读李健答案【篇一:科技英语阅读(李健版)翻译u3】物的适应性植物为了生存也必须像人类和动物一样适应周边的环境。
生存就意味着竞争,我们很难想象植物之间的竞争,但它往往又存在的。
首先,不同的植物之间会争夺阳光、空气、土壤和水。
其次,植物也会与那些吃它或者威胁到它生存环境的人类和动物竞争。
再次,植物所处的环境也可能也是有敌对性的或者不利于植物生长的。
怎样才能有足够的阳光、水分、空气和土壤?气温的冷热就是植物生长的主要因素吗?光对于植物来说是最基本的,尤其是对于绿色植物来说。
绿色植物在光下能制造养分——这是一种被称为光合作用的过程,而光也能影响水分蒸发的速率和花的形成。
温度也是必须考虑的因素。
对于大多数植物来说,所处的温度低于一度或者高于四十三度都将对其造成严重的损伤甚至死亡。
而温度也直接影响了种子的萌芽以及开花,当然温度也决定了它们的地理分布。
没有水植物也是无法生存的。
有些植物的生长过程需要大量的水分,因此潮湿的空气、大量的降水以及溪流湖泊和湿润的土壤对于植物都是重要的。
大多数植物需要有足够空气。
大气中所包含的一些必要的气体包括:氧气、二氧化碳、水蒸气和氮气。
空气移动所产生的风对于植物也有很大影响。
风有助于传播花粉、孢子和种子从而将它们播种在各种地方,但强风也有可能折断或者损害植物,尤其是大树。
而大风吹走了一些有养分的土壤,也会加快水分的蒸发甚至使植物缺水。
土壤对于陆生植物来说是必不可少的。
大部分植物生长在自然土壤里:其中包含着它的湿度、酸度、矿物成分、含氧量。
植物生长也会受到其他竞争生物的影响。
它必须能适应寄生菌、饥饿的鸟类、牛羊等食用叶子的动物,但植物也需要动物帮助传播花粉以及播洒种子。
有树叶和枝干的树以及灌木向我们展示了它们的适应性,这也告诉了我们植物是怎样获得最大量的光和空气的。
和那些山毛榉树、榆树、橡树、苹果树和栗子树一样,它们有一些芽最初是垂直生长的然而另一些却变成了水平生长。
为了能得到最多的阳光,一些垂直生长的枝芽会螺旋缠绕生长以至于不会遮挡到自己下边的叶子。

科技英语阅读与翻译(李健)第二章设想一下:在一个新的产业诞生之际, 你目=睹见证了这一切! 这个产业是在前所未有的新技术基础上发展起来的, 其中包括一些实力雄厚企业销售的高度专业化商务设备, 还有越来越多的新兴公司生产的新奇玩具、为玩具藏家青睐的机巧装置, 以及其他一些奇特有趣的特殊产品。
但同时, 这还是一个缺乏行业标准和平台的、尚不成规模的产业。
项目复杂, 进步缓慢, 实际应用更是少之有少。
事实上, 尽管对这个产业的未来充满热情和希望,但是没有人能明确地说出什么时间- 或究竟是否有可能-它能取得关键性的规模发展。
但是,若真能实现发展, 那么,它很可能改变整个世界。
当然, 上述描述可算是上世纪70 年代中期计算机产业的写照, 也就在那时, 保罗·艾伦和我成立了微软公司。
当时,部分大企业、政府部门和其他一些机构都在使用笨重、昂贵的主计算机进行后台运算。
知名大学和大型工业实验室的研究人员正试图建造出最基本的构件, 以使信息化时代的到来成为可能。
当时英特尔公司刚刚推出他们的8080 微处理器,雅达利公司正在销售一款流行电子游戏“乒乓”。
而在国产计算机俱乐部里,爱好者急切地努力探索这种新技术带来的好处究竟是什么。
但当时我脑海中所萦绕的则是更具前瞻性的问题:机器人产业即将作为一项新兴的产业而崛起,其当时的发展同30 年前计算机的发展如出一辙。
想想看, 目前汽车组装线上使用的制造型机器人已替代了昔日的主计算机。
这个产业其他的典型产品包括可进行外科手术的机器手, 在伊拉克和阿富汗用于路边及地面排雷的侦察机器人, 以及可以进行地板吸尘的家用机器人。
电子产品公司还推出了可模仿人类、或是狗、恐龙等的机器人玩具, 而玩具收藏者们正迫不及待地想要猎取一套乐高公司生产的最新机器人系列玩具。
与此同时, 世界尖端科技人员正试图解决机器人技术中最棘手的难题, 诸如视觉识别、远程操控、以及学习型机器等问题, 而且他们正在不断获得成功。

正在消失的计算机到2010年,我们将被计算机包围吗?是的,但我们却觉察不出来。
—比尔•盖茨(微软公司总裁和首席软件设计师)几年后,普通家庭娱乐系统可能与现在并没有太大的区别,但它很可能具有网络连接功能,用来下载和播放数字音乐和视频,在电视上显示艺术作品集和歌曲的名字,甚至收到重要邮件时打断正在播放的内容来提示你。
它将拥有一个中央处理器、磁盘存储器、制图硬件和某种直观的计算机用户界面。
如果再在加上一个无线鼠标和键盘,这个家庭娱乐系统看起来便很像是一台个人电脑。
人们会大量购买和使用这些系统吗?当然会。
他们会认为这种系统就是电脑吗?也许不会。
根据格特纳信息咨询公司(一家美国研究公司)的统计,世界计算机业在2002年销售了第10亿台个人电脑,而还有10亿台电脑预计在此后的6年中生产出来。
第一批的10亿台电脑几乎都是传统的台式机和笔记本电脑,但第二批的10亿台电脑将会明显不同,人们对它们进行了尽可能的完善,使它们能更好的按照人们的期望运作,例如便签大小的电脑,开会时我们可以用它来做笔记,或是躺在床上阅读电子邮件;娱乐型电脑,用来在客厅电视上播放音乐和电影;袖珍型电脑,用它无论在哪都能与他人保持联系。
除此之外,还有各种数量庞大的嵌入式计算机(如在手机、加油站和零售终端设备中使用的计算机),在功能和复杂性方面正迅速赶上台式电脑。
据估计,有意无意美国人每天会接触到大约150个嵌入式计算机系统。
这些系统使用了现在生产的90% %的微处理器,它们将不可避免地呈现出更多个人电脑的特点,而且能够与传统PC机进行无缝对接。
这一系统将无处不在。
根据半导体工业协会的调查,在2001年,世界芯片业为地球上的每位个男士人,女士妇女和儿童生产了大约6千万个晶体管,这一数字到2010年将上升为10亿。
与此同时,今天的多功能PC机将继续在大多数人的生活中发挥重要(而且是越来越重要)的作用,但其中心地位将体现在今天大部分人不认为是“电脑”的各类智能设备中。

科技英语阅读与翻译(李健)---unit3 Dark nergy
As astronomers have explored this new phenomenon, they have found that, in addition to determining the overall expansion rate of the universe, dark energy has long-term consequences for smaller scales. As you zoom in from the entire observable universe, the first thing you notice is that matter on cosmic scales is distributed in a cobweblike pattern--a filigree of filaments, several tens of millions of light-years long, interspersed with voids of similar size. Simulations show that both matter and dark energy are needed to explain the pattern.
According to models, dark matter began to clump immediately after the big bang, forming spherical blobs that astronomers refer to as "halos." The baryons, in contrast, were initially kept from clumping by their interactions with one another and with radiation. They remained in a hot, gaseous phase. As the universe expanded, this gas cooled and the baryons were able to pack themselves together. The first stars and galaxies coalesced out of this cooled gas a few hundred million years after the big bang. They did not materialize in random locations but in the centers of the dark matter halos that had already taken shape.

Unit 1 EnvironmentEarth’s Health in Sharp Decline, Massive Study Finds大规模研究发现:地球的“健康”每况愈下The report card has arrived from the largest ever scientific Earth analysis, and many of the planet’s ecosystems are simply not making the grade.有史以来对地球进行的最大规模的科学分析结果表明,地球上的许多生态系统都达不到标准。
The UN-backed Millennium Ecosystem Assessment Synthesis Report found that nearly two-thirds of Earth’s life-supporting ecosystems, including clean water, pure air, and stable climate, are being degraded by unsustainable use.由联合国主持的《千年生态系统评估综合报告》指出,由于不可持续的使用,地球上将近三分之二的用来维持生命的生态系统(包括干净的水源、纯净的空气以及稳定的气候)正遭受破坏。
Human has caused much of this damage during the past half century.

By far the most common genetically modified (GM) organisms are crop plants. But the technology has now been applied to almost all forms of life, from pets that glow under UV light to bacteria which form HIV- blocking "living condoms" and from pigs bearing spinach genes to goats that produce spider silk.到目前为止最常见的转基因生物体是农作物。
然而,这项技术现在已经应用于几乎所有形态的生命,从宠物在紫外线照射下发光到构成HIV-blocking 的“活的安全套”的细菌,从继承菠菜基因的猪到生产蜘蛛丝的山羊。
GM tomatoes, as puree, first appeared on British supermarket shelves in 1996 (a different fresh GM tomato first appeared in the US in 1994), but the consumer furore that surrounded GM technology did not erupt until February 1999.This was because a controversial study suggested that a few strains of GM potatoes might be toxic to laboratory rats.Those experiments, subsequently criticised by other experts, were carried out in Scotland by biochemist Arpad Pustzai.转基因西红柿酱, 在1996年第一次出现在英国的超市货架上(1994年不同的新鲜番茄在美国首次出现),但直到1999年2月消费者对基因技术的愤怒才爆发。

芝加哥的屋顶绿化由于当城市中宝贵的房屋建筑用地已所剩无几,城市规划者开始将目光转向空中。
寻找绿色空间也不例外。
欧洲的绿色屋顶长期以来为人们提供了环境、审美和经济方面的利益。
这种想法是否也会植根在美国植根呢?在伊利诺伊州芝加哥市,当市长理查德•戴利看到了欧洲花园般的屋顶之后,便开始了绿色屋顶的创意。
在最近的一次电话采访时他说:“我认为,如果把芝加哥所有平坦的屋顶都利用起来,可以开辟数千英亩的土地用于美化环境,还有利于建筑物供暖、降温,以及进入排污系统的雨水控制。
”他继续说:“当你透过窗户眺望看这个城市时,你看到的不是钢筋混凝土,而是为对环境的美化。
所以我想,这就是我们应该做的到事情。
”绿色屋顶通常是由无需经常维护的抗旱植物组成(如景天属暑天景植物)。
这些屋顶的厚度均小于4英寸(10厘米),可直接在上面种植或制作成已有植物预先栽种在上面的种植垫。
即使斜屋顶也可以进行绿色屋顶处理。
利用率较高的绿色屋顶系统可以包括多种植物和园林要素,如树木,但只有在平坦的屋顶上才行。
这种绿色屋顶需要更深的种植材料或土壤替代物,它们更重,更昂贵,并且需要更多的维护。
绿化屋顶的最大好处之一是水资源管理。
它们能吸收落在屋顶上的大约50%%-60%%的雨水,这些雨水一部分通过植物蒸发(或“呼气”)回到大气中而消耗掉了,另一部分水保留在土壤中或其他培养媒介中,。
其余的则缓慢地、在人们的控制下缓慢地流入城市雨水排水系统,这个过程有助于抑制城市供水系统中大量雨水激增的现象,而要扩充该系统的费用是很昂贵的。
位于东兰辛伊斯兰莘市的密歇根州立大学植物和土壤学家布拉德•罗说:“在许多城市,甚至一场雷雨就可能造成(雨水的排水系统)溢流,并与污水混在一起。
谁知道它们会流到哪儿去呢?”绿色屋顶的支持者还列举出其他好处,如节省能源。
一个绿色屋顶可以降低多少能源成本,这取决于屋顶类型和使用该屋顶当地的气候。
比较温暖的气候是节省能源的最佳条件,因为与降低取暖费相比,使用绿色屋顶能够更有效地减少空调费用。

科技英语阅读李健课文翻译Thanksgiving Day 美国感恩节The American Thanksgiving is a holiday set aside each year in the United States to honor the blessings of the year and to offer thanks. It is one of the oldest holidays in America, having been celebrated since the time of the earliest settlers.每年美国都要为庆祝全年之恩与感激而定下例假,这就是美国人所庆祝的感恩节。
它是美国最古老的节日之一,早在最早的移民时期就开始庆祝了。
This holiday began when people first arrived at Plymouth colony in what we now call Massachusetts. They had sailed all the way to America onboard the Mayflower, a small and uncomfortable sailing ship. During their first winter, they were welcomed and helped by the Indians of the area. To celebrate their first successful harvest, they held a great feast.这个节日始于当时最早到达位于今麻省的普利茅斯殖民地的人们。
他们乘坐着一艘名叫“五月花号”的小而不舒服的帆船穿过了大海,抵达美洲。
第一个冬天里,当地的印第安人对他们表示欢迎和援助。
为庆祝第一次成功的丰收,他们举行了盛大的宴会。
At the time, many of the English settlers were earning aliving by farming and hunting, so the most common foods at the meal were fish, wild game, and local vegetables. The food was cooked over an open fire.当时,许多英国开始通过种植和捕猎来谋生,所以宴会上最常见的食物是鱼类、野味、当地的蔬菜,用火来烹饪。
Unit 9 How I Found My Voice习题答案综合教程四
Unit 9 How I Found My Voice之勘阻及广创作Key to the ExercisesText comprehensionI .Decide which of the following best states the author's purpose of writing.AII. Judge, according to the text, whether the following statements are true or false.1. T (Refer to Paragraph2.)2. T (Refer to Paragraph 4.)3. F (Refer to Paragraph 7. The narrator did not communicate with the farm animals in their language. As he could not speak before strangers due to his timidity, he could only talk to animals as a way of venting his feelings.)4. F (Refer to Paragraph 13. The professor challenged him over his authorship not because he did not believe he had written the poem but because he wanted to provoke the boy to speak the words in public and tried to help him overcome his stuttering in this way.)5. F (Refer to Paragraph 14. He stared at ProfessorCrouch in disbelief and even felt angry at what he said.)6. T (Refer to Paragraph 29.)III. Answer the following questions.1.Refer to Paragraph2. Because the great achievements were far beyond the expectations of such a poor stutterer as he used to be. When he was young he was completely unable to speak in public due to his serious stuttering. Thus he could never imagine that he would make such good achievements.2. Refer to Paragraph 4. Because he felt that the place he moved to was drastically different climatically and culturally from where he had been.3. Refer to Paragraph 6. Because he wanted to avoid the humiliation he suffered there for his stuttering.4. Refer to Paragraph 7. Because the animals never laughed at him and he was not nervous at all when he talked to them as a way of venting his feelings.5. Refer to Paragraph 9. Because he loved English classics, especially poetry, which was one of the subjects taught at the narrator's school. His deep love for poetry was vividly described in the metaphor: "He held a book of poems as if it were a diamond necklace,turning pages as if uncovering treasures."6. Refer to Paragraphs 13?8. It was Professor Crouch's trick. When the narrator handed in his poem, Crouch purposefully challenged him for his authorship. Consequently the narrator was provoked into reciting his poem in the presence of his classmates without stuttering. IV. Explain in your own words the following sentences.1. He wanted very much to be a teacher of our school.2. We found a strong connection between us.3. I supported myself by sweeping floors of off-Broadway stages before there was any new role for me to play.4. He was still living in a world that was exciting and lively because of all the beautiful poems he had memorized.Structural analysis of the textThis autobiographical narrative can be divided into the following three parts:Part 1, Paragraphs 1?: the author presents a striking contrast between his successful career as an actor and television announcer and his severe stuttering problem in his early childhood.Part 2, Paragraphs 3?2: the author recollects how hishigh school teacher, Professor Crouch, helped him to overcome his stutter and find his voice.Part 3, Paragraphs 23?9: the author tells the reader what achievements he made after he overcame his stuttering problem and how grateful he is to his teacher, "the father of my resurrected voice."Rhetorical features of the textThe New Testament is repeated because the author takes it as his greatest honour to read such an important book on tape. It is distributed this way because the author wants to tell the readers from the beginning of his personal account what achievements he has made since he got over his stuttering problem and express his gratitude to the father of his resurrected voice. By mentioning New Testament again at the end of the narrative, the author successfully harks back to the opening paragraph and thus unifies the text into an organic whole.Vocabulary exercisesI.

Many sea animals give out light in the dark and some have sharp teeth.During the day, there is enough light. Here, under the sea, everything is blue and green. When fish swim nearby, you can catch them with your hands. When you have bottles of air on your back, you can stay in deep water for a long time. However, you can’t dive too deep. And you must be very careful when you dive in deep water.The deep sea is not an easy place to live in. It’s cold, and it’s dark, too. The deeper it is, the less sunlight there is.

At the depth of 3,000 feet under the sea, all animals can find their way by seeing.(B) (8%)Orangutans are large, intelligent apes, which are native to the islands of Indonesia and Malaysia. Orangutans have long arms and reddish-brown hair. Their arms are twice as long as their legs. Quiet and peaceful, they live alone or with their young high up in the treetops and they travel about by leaping from one tree to another.The name “Orangutan” originates from the Malay term “Orang Hutan”, meaning “person of the forest”. Orangutans are primates like humans and chimpanzees (⿊猩猩). They are the only species of ape that comes from Asia, as the other ape species come from Africa. Orangutans live for about 35 years in the wild and spend their first six years with their mothers. Female orangutans only give birth once every eight years, which is the longest period between births of any mammal. Females can weigh about 45 kilograms, and males can weigh over 100 kilograms. Males have large throat sacs (囊) that they use to make loud, long calls to females and to warn away other males. Orangutans are very intelligent, and only humans are smarter primates than orangutans. Adult orangutans are able to teach young ones how to make tools and find food. Their learning abilities and problem solving skills are better than those of chimpanzees.Fruit makes up 65% of their total diet. They spend most of their time looking for food and eating leaves, shoots, seeds, bark, insects, and bird eggs. Orangutans build small nests high in the branches of trees in which they take an afternoon nap, and larger nests in which they spend the night. Orangutans are solitary (独居的) animals, and males and females come together only to mate.Unfortunately, there are only about 45,000 orangutans left in the wild, and this species of primate may disappear within a decade because of deforestation (采伐森林), mines, forest fires, poachers (偷猎者), plantations and the illegal commerce in wild animals. If we don’t save this fellow primate from extinction, do we lose the right to complain if we, too, someday face extinction?29. What does the name “orangutan” mean?A. People of the city.B. Person of the forest.C. Animal of the forest.D. Person of Asia.30. Where can you find orangutans in the wild?A. China and Japan.B. Vietnam and Thailand.C. Indonesia and Malaysia.D. Laos and Thailand.31. Which of the following statements about male orangutans is not true?A. They can weigh over 100 kilograms.B. They have large throat sacs that they use to make loud, long calls to females and towarn away other males.C. They live for about 35 years in the wild.D. They often live with their female partners and their babies.32. What is the main point of this article?A. Orangutans are large, intelligent apes with long arms and reddish-brown hair, and they are native to the islands of Indonesia and Malaysia.B. Orangutans come from Asia while all the other ape species come from Africa.C. The number of orangutans is decreasing because of deforestation, mines, forest fires,poachers, plantations and the illegal commerce in wild animals.D. Orangutans are intelligent, peaceful, solitary animals that live almost all the time in trees, and they are threatened by the activities of humans.以下试题答案直接写在试卷上。
