　　California Gives Green Light to Space Solar Power

　　Energy beamed down from space is one step closer to reality，now that California has given the green light to an agreement that would see the Pacific Gas and Electric Company buy 200 megawatt (兆瓦)of power beamed down from solar-power satellites beginning in 2016．But some major chal lenges will have to be overcomed if the technology is to be used widely．

　　A start-up company called Solaren is designing the satellites，which it says will use radio waves to beam energy down to a receiving station on Earth．

　　The attraction of collecting solar power in space is the almost uninterrupted sunshine available in eosynchronous(与地球同步的)orbit．Earth-based solar cells，by contrast，can only collect sun．

　　Light during daytime and when skies are clear．

　　But space-based solar power must grapple(努力克服)with the high cost per kilogram of launching things into space，says Richard Schwartz of Purdue University in West Lafayette，Indiana， "If you're talking about it being economically viable or power of the Earth，it's a tough go．"he says.

　　Cal Boerman，Solaren's director of energy services，says the company designed its satellites with a view to keeping launch costs down．"We knew we had to come up with a different，revolu-tionary design，"he says．A patent the company has won describes ways to reduce the system'Sweight，including using inflatable minors to focus sunlight on solar cells，so a smaller number cancollect the same amount of energy．

　　But using minors introduces other chaHenges，including keeping the solar cells from overhea-ting，says Schwartz．"You have to take care of heat dissipation(散发)because you're now concen-trating a lot of energy in one place，"he says．According to the company's patent，Solaren's solarcells will be connected to radiators to help keep them cool．

　　Though Boerman says the company believes it can make space-based solar power work，it is notexpecting to crowd out other forms of renewable energy．Laws in California and other states requireincreasing use of renewable energy in coming years，he points out．"To meet those needs，we're go-ing to need all types of renewable energy sources，"he says．

　　16．Solar-power satellites will use radio waves to beam energy down from space．

　　A．Right

　　B．Wrong

　　C．Not mentioned

　　17．Solaren is going to design 200 solar-power satellites．

　　A．Right

　　B．Wrong

　　C．Not mentioned

　　18．Space-based solar cells could collect solar power only when skies are clear．

　　A．Right

　　B．Wrong

　　C．Not mentioned

　　19．One advantage of space-based solar power system is that it is economical．

　　A．Right

　　B．Wrong

　　C．Not mentioned

　　20．Inflatable minors are used to reduce the space-based solar power system．

　　A．Right

　　B．Wrong

　　C．Not mentioned

　　21．Space-based solar power will rule out other forms of renewable energy sources．

　　A．Right

　　B．Wrong

　　C．Not mentioned

　　22．Many countries will grant permission for the use of spaced-based solar power soon．

　　A．Right

　　B．Wrong

　　C．Not mentioned

　　Natural Gas

　　1 Natural gas is produced from reservoirs deep beneath the earth's surface．It is a fossil fuel

　　(矿物质燃料)，meaning that it is derived from organic material buried in the earth millions of yearsago．The main component of natural gas is methane(甲烷)．

　　2 The popularity and use of clean natural gas has increased dramatically over the past 50 years as pipeline infrastructure(基础设施)has been installed to deliver it conveniently and economically to millions of residential，commercial and industrial customers worldwide．Today，natural gas serviceis available in all 50 states in the U．S．，and is the leading energy choice for fueling Americanhomes and idustries。More than 65 million American homes use natural gas．In fact，natural gas isthe most economical source for home energy needs，costing one-third as much as electricity．In addi-tion to heating homes，much of the gas used in the United States is used as a raw material to manu-facture a wide variety of products，from paint，to fibers for clothing，to plastics for heahhcare，con-puting and furnishings．Natural gas is also used in a significant number of new electricity-generating power plants．

　　3 Natural gas is one of the safest and cleanest fuels available．It emits less pollution than oth-er fossil fuel sources．When natural gas is burned，it produces mostly carbon dioxide(二氧化碳) and water vapor-the same substances emitted when humans exhale．Compared with some other fos-sil fuels，natural gas emits the least amount of carbon dioxide into the air when combusted(燃烧)， making natural gas the cleanest burning fossil fuel of a11．

　　4 The United States consumes about one-third of the world'S natural gas output，making it the largest gas-consuming region in the world．The U．S．Department of Energy'S Energy Information Ad-ministration forecasts that natural gas demand will grow by more than 50 percent by 2025．

　　5 There are huge reserves of natural gas beneath the earth's surface．The largest reserves of natural gas can be found in Russia，West and North Africa and the Middle East．LNG(液化天然气)has been produced domestically and imported in the United States for more than four decades．

　　Today，the leading importes of LNG are Japan，Korea，France and Spain．

　　23．Paragraph 2_________．

　　24．Paragraph 3________．

　　25．Paragraph 4_________.

　　26．Paragraph 5________．

　　A．Popularity and use of natural gas

　　B．Natural gas reserves and supply

　　C．Natural gas prices

　　D．Clean fuel of choice

　　E．Disadvantages of natural gas

　　F．Natural gas consumption

　　27．Natural gas is stored deep________．

　　28．Natural gas is recognized as the most economical energy source_________．

　　第4部分：阅读理解(第3l～45题，每题3分，共45分)

　　下面有3篇短文，每篇短文后有5道题。请根据短文内容,为每题确定1个最佳选项。

　　第一篇

　　How the First Stars in the Universe Came into Existence

　　How the first stars formed from this dust and gas has been a burning question for years，but a state-of-the-art computer simulation now offers the most detailed picture yet of how these first stars in the universe came into existence，researchers say．

　　The composition of the early universe was quite different from that of today，and the physics that governed the early universe were also somewhat simpler．Dr．Naoki Yoshida and colleagues in Japan and the U．S．incorporated these conditions of the early universe，sometimes referred to as the "cosmic dark ages，"to simulate the formation of an astronomical object that would eventually shine its light into this darkness．

　　The result is a detailed description of the formation of a protostar-the early stage of a massive primordial star of our universe，and the researchers'computer simulation，which has been called a "cosmic Rosetta Stone．"sets the bar for further investigation into the star formation process．The question of how the first stars evolved is so important because their formations and eventual explo-sions provided the seeds for subsequent stars to come into being．

　　According to their simulation，gravity acted on minute density variations in matter，gases，and the mysterious"dark matter''of the universe after the Big Bang in order to form this early stage of a star-a protostar with a mass of just one percent of our sun．The simulation reveals how pre-stellar gases would have actually evolved under the simpler physics of the early universe to form this protostar．

　　Dr．Yoshida's simulation also shows that the protostar would likely evolve into a massive star capableof synthesizing heavy elements，not just in later generations of stars，but soon after the Big Bang．

　　"This geneal picture of star formation，and the ability to compare how stellar objects form in different time periods and regions of the universe，will eventually allow investigation into the originsof life and planets，"said Lars Hernquist，a Professor of Astronomy at Harvard University and a coauthor of this latest report．"The abundance of elements in the universe has increased as stars haveaccumulated，"he says，"and the formation and destruction of stars continues to spread these ele． ments further across the universe．So when you think about it．a11 of the elements in our bodies originally formed from nuclear reactions in the centers of stars，long ago．"

　　Their simulation of the birth of a protostar in the early universe signifies a key step toward theambitious goal of piecing together the formation of an entire primordial star and of predicting the massand properties of these first stars of the universe．More powerful computers，more physical data，andan even larger range will be needed for further calculations and simulations，but these researchers hope to eventually extend this simulation to the point of nuclear reaction in．itiation-when a stellar ob． ject becomes a true star．

　　"Dr．Yoshida has taken the study of primordial star formation to a new level with this simulation，but it still gets us only to the halfway point towards our final goal．It is like laying the foundation of a skyscraper，"said Volker Bromm，Assistant Professor of Astronomy at the University of Tex． as，Austin and the author of a companion article．"We must continue our studies in this area to un-derstand how the initially tiny protostar grows，layer by layer，to eventually form a massive star．Buthere，the physics become much more complicated and even more computational resources are needed．"

　　31．According to the first two paragraphs，the early universe_______．

　　A．was governed by simpler physics

　　B．got fewer stars shinning in it

　　C．started over 13 billion years ago

　　D．was composed in a way similar to that of today

　　32．What can the state-of-the．art computer simulation tell us about?

　　A．How the Big Bang occurred about 13 billion years ago．

　　B．How"cosmic dark ages"came into existence．

　　C．How dust grains and gases were formed after the Big Bang．

　　D．How the first stars canle into being after the Big Bang．

　　33．What does the"astronomical object"in paragraph 2 refer to?

　　A．cosmic dark ages．

　　B．dust grains and gases．

　　C．a protostar．

　　D．the early universe．

　　34．According to paragraph 4，what is NOT true about a protostar?

　　A．It developed into a massive star during the Big Bang．

　　B．It evolved from pre-stellar gases．

　　C．It was able to integrate heavy elements when evolving into a massive star．

　　D．It had a mass of one percent of the sun．

　　35．According to the last paragraph，all of the following are goals of the simulation project EXCEPT

　　A．to know more about the mass and properties of the first stars of the universe

　　B．to simulate the process of how the early universe began

　　C．to apply the simulation to the study of nuclear reaction initiation

　　The Iceman

　　On a September,day in 1991，two Germans were climbing the mountain between Austra and Ita． 1y．High up on a mountain pass，they found the body of a man lying on the ice．At that height (10，499 feet，or 3，200 meters)，the ice is usually permanent，but 1991 had been an especially

　　warm year．The mountain ice had melted more than iust usual and so the body had come to the surface．It was lying face downward．The skeleton(骨架)was in perfect condition except a wound on the head．remains of some clothes．The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth boots．Nearby was a pair of gloves made of tree bark (树皮)and a holder for arrows．

　　Who was the man?How and when had he died?Everybody had a different answer to these questions．Some people thought that it was from this century，perhaps the body of a soldier who died in World War I，since several soldiers had already been found in this area．A Swiss woman who believed it might be her father，who had died in those mountains twenty years before and whose body had never been found．The scientists who rushed to look at the body thought it was probably much older，maybe even a thousand years old．

　　With modem dating techniques，the scientists soon learned that the iceman was about 5，300 years old．Born in about 3300 B．C．，he lived during the Bronze Age in Europe．At first scientists thought he was probably a hunter who had died from an accident in the high mountains．More recent evidence，however，tells a different story．A new kind of X-ray shows an arrowhead still stuck in his shoulder．It left only a tiny hole in his skin，but it caused internal damage and bleeding．He almost certainly died from this wound，and not from the wound oil the back of his head．This means that he was probably in some kind of battle．It may have been part oi a large war，or he may have beenfightiing bandits．He may even have been a bandit himself．

　　By studying his clothes and tools，scientists have already learned a great deal from the Iceman about the times he lived in．we may never know the full story of how he died，but he has given usimportant clues to the history of those distant times．

　　36．The body of the iceman was found in the mountains mainly because_________．

　　A．he was lying on the ice

　　B．two Germans were climbing mountains

　　C．the melted ice made him visible

　　D．he was just on a mountain pass

　　37．What can be inferred from paragraph 2?

　　A．The iceman was killed while working．

　　B．The iceman could have died from the wound in the head．

　　C．The iceman lived a poor life．

　　D．The iceman was struck dead from behind．

　　38．All the following are assumptions once made about iceman EXCEPT_____________．

　　A．he was a soldier in World War I

　　B．he came from Italy

　　C．he was a Swiss woman's long-lost father

　　D．He was born about a thousand years ago

　　39．The scientists made the deduction that the iceman_________．

　　A．was hit in the shoulder by an arrowhead

　　B．was probably in some kind of a battle

　　C．had got a wound on the back of his head

　　D．has a tiny hole in his skin causing his death．

　　40．The word"bandits"in paragraph 4 could be best replaced by________．

　　A．robbers

　　B．soldiers

　　C hunters

　　D．shooters

　　Scientists Make Sweet Discovering

　　Good news for chocoholics：the treat preferred by millions all over the world is good for you， according to American researchers at the University of California．Chocolate contains substancescalled flavonoids that can help maintain a healthy heart and good circulation．The researchers havediscovered that cocoa acts like aspirin and that eating a bar of chocolate has also been shown to release endorphins in the body：these chemicals help to reduce pain and stress and make you feel happy.

　　The Olmec Indians of Mexico and Central America were the first to grow cocoa beans，in about1500 BC，and the Mayas were drinking unsweetened coca hundreds of years before it became fashionable in Europe．

　　In 1544，a delegation of Mayan nobles visited Philip of Spain and gave him jars of cocoa as a gift．Cocoa soon became fashionable in Spain and Portugal．The Spanish were the first to add sugarto their cocoa drink．

　　By the middle of the century，solid chocolate was becoming familiar．In 1765，James Baker and John Hanan opened the first chocolate mill in the United States，introducing chocolate to the average citizen．In 1896，in Switzerland，Daniel Peter had the idea of adding milk in the chocolate-making process and produced the first milk chocolate．

　　Since then，chocolate has grown enormously in popularity．One of the biggest chocolate-eatingnations is Britain where the average man，women，and child eats nine kilos of chocolate a year．Infact，chocolate is the number one comfort food and there are more chocoholics in Britain than any where else in the world．Researchers warn that although chocolate is good for you，it should be eatenin small quantities and with no added milk．

　　41．Why is chocolate good for heaa and circulation?

　　A．It reduces pain and stress．

　　B．It containS substances called flavonoids．

　　C．It releases endorphins in human body．

　　I Just Know How You Feel

　　Do you feel sad?Happy?Frustrated?Insouciant?Exonerated?Infuriated?Do you think that the way you display these emotions is unique?Well，think again．Even the expression of the most personal feelings CaB be divided into groups，classified，and perhaps，taught．This week sees the publication of Mind Reading，an interactive DVD-rom displaying every possible human emotion．It demonstrates 412 distinct ways in which we feel：the first visual dictionary of the human heart．

　　The attempt to classify the human heart began with Darwin．His The Expression of the Emotions in Man and Animals，published in 1872，divided the emotions into six types-anger，fear，sadness， disgust，surprise and enjoyment．________(46)．

　　Every other feeling，of which there may be thousands，was thought to derive from this six-strong group．More complex expressions of emotion were likely to be learned and therefore more specific to each culture．An incredulous or indignant Pacific islander might not be able to show an Essex girl exactly how she felt．

　　But now it is believed that，whereas gestures do not cross cultural boundaries well，many more facial expressions than Darwin's half-dozen are shared worldwide．___________(47)．The Mind Reading is a systematic record of each of these expressions being acted out．

　　The project was conceived by Professor Simon Baron-Cohen of the autism research centre in Cambridge as an aid for people with autism，who have difficulty both reading and expressing emotion．But it quickly became apparent that it had broader uses．Novelists，actors and portrait painters all need to draw upon a wide range of emotional expression，and teachers could use it for classes in personal and social development．

　　Baron-Cohen's team first had to decide what counted as an emotion．________(48)．Using thisdefinition，1，512 emotion terms were identified and put to a panel who had to decide if each repre． sented a separate emotion，or if they were synonyms．That list was whittled down to 412，arranged in24 groups．from"afraid"to"wanting"．

　　Once the emotions were classified．a DVD seemed the most efficient way to display them．In Mind Reading，each expressions is acted out-six times，by six different actors-in three seconds．

　　_______(49)．The explanation for this is simple：we may find it difficult to describe emotions using words，but we instantly recognize one when we see it on someone's face．"It was really clear when the actors had got it right，"says Cathy Collis，who directed the DVD．

　　BUt though we find it difficult to describe many emotions，we instantly recognize one when we see one．"Even when the actors were strnggling to get an emotion，there was a split second when it was absolutely there．It was really clear when they'd got it，"Cathy Collis，who directed the DVD． "Although the actors were given some direction，they were not told which facial muscle they should move．"She added__________(50)For example，when someone feels contempt，you can't say for certain that their eyebrows always go down．

　　Someone who has tried to establish such rules is the American Professor Paul Ekman．who has built a database of how the face moves for every emotion．The face can make 43 distinct muscle movements called"action units"．These can be combined into more than 10．000 visible facial shapes．Ekman has written out a paper of facial muscular movements to represent each emotion．

　　A．We thought of trying to describe each emotion but it would have been almost impossible tomake clear rules for this

　　B．These particular muscles aye difficult to control，and few people can do it．

　　C．Research has also been done to find out which areas of the brain read the emotional expressions．

　　D．They decided that it was a mental state that could be preceded by"I feel"or"he looks"or "she sounds"．

　　E．He said that the expression of theses feelings aye universal and recognizable by anyone，from any culture．

　　F．Any other method of showing all the 412 emotions，such as words，would have been far less efiective．

　　Obtaining Drinking Water from Air Humidity

　　Not a plant to be seen，the desert ground is too dry．But the air contains water，and research scientists have found a_________(51)of obtaining drinking water from air humidity．The system isbased completely on renewable energy and is therefore autonomous．

　　Cracks permeate the dried-out desert ground and the landscape bears testimony to the lack of water．But even here，where there are no lakes，rivers or groundwater，considerable quantities of water are stored in the air．In the Negev desert in Israel，for example，annual average relative air hu-midity is 64 percent-in every cubic meter of air there aye 11．5 milliliters of water．

　　加利福尼亚州批准空间太阳能电站

　　使用从太空照下的能源已经离现实近在咫尺了，因为加利福尼亚州已经以协议的形式批准了。协议规定：从2016年起，太平洋天然气和电力公司将购买200兆瓦的从太阳能电站的卫星上发送来的电力。但这项技术要广泛使用，仍有一些挑战需要克服。

　　发出这一设想的公司Solaren正在设计一颗卫星。公司称这颗卫星将会使用无线电波将能源发送到地球上的接收站。

　　在太空收集太阳能这一设想的吸引人之处在于它是目前在地球同步轨道上收集阳光受阻碍最少的方式。与此截然不同的是，在地球上的太阳能电池只能在白天且无云的时候收集阳光。

　　但在太空的太阳能工厂必须努力克服的问题是：向太空发射一公斤的物品都要付出高昂代价。印第安纳州普渡大学拉法叶校区的Richarci Scllwartz说："如果你要说的是让这一设想从经济角度上可行，从而供应地球能量，这是一条很艰难的道路。"

　　Solaren公司的能源服务部门的经理Cal Boerman说公司设计这一卫星时已考虑到将发射成本降低。他说："我们知道我们必须想出一个与众不同的，有革新意义的设计。"这家公司的一项专利说明了降低此系统重量的多种方法，包括使用可充气的镜子向太阳能电池板聚焦，这样利用较少的太阳能电池板就可以收集到等量的能量。

　　但使用镜子又带来了其他问题，包括防止太阳能电池板过热，Sclawartz提出。"你必须处理好热量散发的问题，因为你将很多能量聚集在一个地方。"他说。按照该公司的专利书描述．Solaren公司的太阳能电池板会被连接到散热板上使其保持冷却。

　　尽管Boerman说这家公司相信它能制造建立在太空中的太阳能发电厂，但它并不会挤掉其他形式的可再生能源。加利福尼亚州的法律以及其他州的法律要求在未来几年增加对可再生能源的利用。他指出："为了满足这些需要，我们需要使用各种可再生能源。"

　　天然气天然气深藏在地球表面下方，它属于矿物燃料，由埋藏在地球上上百万年前的有机物生成。它的主要成分是甲烷。

　　过去50多年，随着管道基础设施的建设将气体便利、经济地输送到世界各地的居住区、商业区和工业区用户，天然气的受欢迎程度和利用程度便迅速增长。如今全美50个州都有天然气服务，并且天然气成为美国家用燃料和工业使用燃料的首选。有超过6500万的美国家庭使用天然气。事实上，天然气是最经济的家庭能源需求，其费用是电的三分之一。除了家庭取暖外，在美国，天然气还被用作油漆、服装纤维、保健用塑料制品、计算设备和家具等多种产品的原材料，其也被用在许多新的发电厂。

　　天然气是现有能源中最安全和最干净的。它释放的污染小于其他矿物燃料。天然气燃烧时主要产生二氧化碳和水蒸汽--与人呼吸产生的物质相同。与其他矿物燃料相比，天然气燃烧时释放到空气中的二氧化碳最少，因此它是最洁净的矿物燃料。

　　美国消费世界天然气总产量的三分之一，是世界上最大的天然气消费地区。美国能源部的能源信息行政部预计到2025年，天然气的需求将会超过50％。

　　地表下面储存有大量的天然气。在俄罗斯、西非、北非和中东地区，天然气的储存量最大。

　　宇宙中最初的星辰是如何产生的?

　　多年来，最初的星辰是如何由尘埃和气体组成的问题一直困扰着人们，然而专家们说，现在一种最先进的电脑模拟系统可以提供宇宙中最初的星辰是如何产生的最详细的图片。

　　宇宙最初的构成同今天的有所不同，而且宇宙早期的主要物理现象也比较简单。Naoki'Yoshida博士同他在日本和美国的同事一起整合了宇宙早期的各种情况，这一时期有时也被称为"宇宙的黑暗时代"，模拟了最终在夜空中闪耀的天体的形成过程。

　　这一研究的结果是对原恒星--宇宙中巨大的原始星辰的早期阶段形成的详细的描述并且有"宇宙的罗塞达石碑"之称的研究人员的电脑模拟系统，为进一步研究星体的形成过程奠定了基础。宇宙中最初的星辰是如何形成的问题非常重要，因为它们的形成及最终的爆炸为随后的星体的形成提供了种子。

　　根据研究人员的模拟系统，重力对物质、气体及宇宙大爆炸后形成的神秘的"黑暗物质" 的密度的微小变化产生了影响，从而形成了星辰的雏形--仅有太阳百分之一大的原恒星。

　　模拟系统为我们展示了组成早期星辰的气体是如何在早期宇宙简单的物理作用下演化形成了原恒星。Yoshida博士的模拟系统还展示了原恒星可能会在宇宙大爆炸刚刚结束就演化成能够合成重元素的巨大的星体，而不是几代以后的星体才能合成。

　　哈佛大学天文学教授同时也是这项报告的合作者Lars Hernquist谈到："星体形成的总图和对比宇宙不同时期和区域星体如何形成的能力将最终让我们能够探索生命和星球的起源。

　　随着星体越来越多，宇宙中的各种元素更加充裕，而且星体的形成和毁灭继续将这些元素传播到宇宙的更深处。所以你想想我们身体的所有元素最初都形成于很久以前星体中心的核反应。"

　　对宇宙早期原恒星诞生的模拟意味着向拼接原始星体形成过程和预测宇宙中最初的星辰的质量和性质的宏伟目标迈出了关键的一步。要进行更进一步的计算和模拟就需要功能更强的电脑，更多的物理数据，甚至更广的研究范围，但是研究者希望最终能将这个模拟结果应用于核反应初期--也就是当一个星状物质变成真正的星辰的时候。

　　德克萨斯州立大学天文学助理教授，一篇相关论文的作者Volker Bromm说："Yoshida博士已经用这个模拟系统把对原始星体形成的研究推到了一个新的水平，但是这离我们最终的目标还很远。这就像是躺在摩天大楼的地基上。我们必须继续在这一领域的研究，从而了解最初的原恒星是如何一层一层长大并最终成为一颗巨大星体的。但是现在，物理现象越来越复杂，而且我们还需要更多的计算资源。"

　　参考译文

　　冰人1991年9月的一天，两位德国人正在攀登位于奥地利和意大利之间的山脉。他们在一个高处山口发现了一具躺在冰上的尸体。冰在这样的高度(10499英尺或3200米)通常是常年不化的．但是1991年是特别暖和的一年，山上的冰比从前消融的更快，因此尸体才显露出来。

　　尸体面朝下躺着，除了头部有伤外，骨架状况很好，有残余的衣物。尸体双手仍然握着斧头的木柄。双脚穿着用皮革和布料做的靴子。在尸体附近有一双树皮做的手套和一个箭筒。

　　他是谁?在什么时候又是怎样死去的呢?人们的解释各异。有人认为他是本世纪的人，

　　有可能是二战时期阵亡的士兵，因为在这附近已经有士兵被发现了。一位瑞士妇女相信他是自己20年前在此去世的父亲，父亲的遗体一直没有被找到。赶去查看的科学家认为这一尸体可能更久远，它甚至有1000岁了。

　　科学家们运用现代数据技术很快获悉这一冰人已有大约5300岁了。他大约出生在公元前3300年，生活在欧洲的青铜器时代。起初科学家们认为他有可能在高山间打猎时发生意外而身亡。然而最近的一些证据却显示另有原因。新型的x光表明他的肩膀上仍有一个箭头，

　　皮肤上只有一个小孔，但却导致内部损伤和失血。几乎可以确定他死于这个伤口，而不是脑后的伤口。这说明他有可能参与过战争。有可能是大型战争的一部分或者他曾和强盗博斗过，甚至他本人就可能是强盗。

　　通过研究他的衣服和工具，科学家们就已经获悉冰人生活的时代的很多内容。我们有可能永远无法知道他死亡的真相，但是他给我们提供了了解那个远古时代的重要线索。

　　科学家的"甜蜜发现''

　　巧克力迷们的好消息：据加州大学的研究者称深受全世界成千上万人喜爱的巧克力对健康很有好处，因为巧克力中合有一种叫类黄酮的物质，它能维护心脏的健康并促进血液循环。

　　研究者们还发现可可会像阿司匹林一样，会在体内释放内啡肽：这些化学物质可以有效缓解疼痛和压力，让你感到谕快。在大约公元前1500年，居住在墨西哥和中关洲的奥尔梅克人首次开始种植可可豆，并且在可可风靡欧洲之前玛雅人已经饮用无糖可可好几百年了。

　　1544年，一个玛雅贵族代表团觐见西班牙国王菲利普时送给他一罐可可作为礼物。很快，可可便在西班牙和葡萄牙流行起来，西班牙人最早在他们的可可饮料里加糖。

　　到了世纪中叶，固体可可开始为人们所熟知。1765年，James Baker和John Harian在美国开办了第一个巧克力作坊，将巧克力介绍给了普通人。1896年，瑞士的Daniel Peter想出了在巧克力制作过程中加牛奶的点子，并生产出了第一块牛奶巧克力。

　　从此，巧克力变得越来越受人们欢迎。巧克力的最大消费国之一是英国。那里的普通人，不论男女还是孩子每年都要吃9公斤的巧克力。实际上，巧克力是顶级的抚慰食品，并且英国是全世界巧克力迷最多的国家。研究者们警告虽然巧克力对我们有好处，但应该少量食用而且不应另加牛奶。

　　参考译文

　　我懂你的心你觉得难过，快乐，灰心，漫不经心，生气吗?你可能认为自己表达这些情感的方式是独一无二的。哦，再想想吧。即使是最为私密的个人感情也可分类。这周推出的Mindl Reacling(头脑阅读仪)，一种可以显示人类每一种可能的情绪的DVD。这种仪器准确地展示我们412种不同的表情，它是第一部可以感受人类内心活动的可视字典。

　　对于人类表情划分的尝试源自于达尔文1872年出版的《人和动物的情感与表达》。这本书中将人的表情划分为六种类型--愤怒、恐惧、悲伤、厌恶、惊喜和快乐。他表示这种感情的表达普遍存在，可以在任何人和任何文化中找到。其他不同的感觉被认为来自于达尔文的分类。更复杂的情感表达或许是后天习得的，因此在不同的文化中具有自己的特色。一个抱着怀疑或愤怒态度的太平洋上的岛民是无法传递给英国埃塞克斯郡的女孩她的感受的。

　　但是现在看来：尽管手势不能很好的跨越文化的界限，但比达尔文所说的六类情感更多的面部表情是为人类所共享的。人们做了研究以期发现大脑的哪个区域读取表情。头脑阅读是一种系统的视觉表情的记录。

　　该项目由剑桥大学自闭症研究中心的教授simon Baron-Collen构想，此中心对自闭症患者，即在阅读和表达情感方面有困难的人，进行一种辅助治疗。但是很快它有了很多更为广泛且显而易见的用途。小说家、演员和肖像画家都需要利用多种的情感表情，甚至老师们把它应用于教授个人和社会发展知识的课堂。

　　Baron-Colaen和他的研究小组首先定义了"情感"，他们认定情感是一种心理状态，常以"我觉得""他认为""她听起来"开头。他们用这种界定方式对1512种情感进行了界定，并呈交给一个评审团，由他们来决定每种情感是一个单独的感情还是都属于同类感情。最终，这个列表减少到412种表情，分成24类，从"害怕"到"希望"。

　　一旦这些情感被定义和归类，那么DVD似乎就成为最为快捷的展示情感的方式了。在头脑阅读中，每种表情都由6个不同的演员在3秒内表演出来。要展示412种表情，其他任何的方法远没有这样有效。原因很简单：我们很难用语言来形容感情，但是当它们出现在某人的脸部时我们会立刻辨认出来，"很明显，演员的表演是到位的。"DVD的导演凯西科利说到。"虽然给了他们一些指示，但并没有告诉演员他们应该动用面部的哪块肌肉。"科利斯女士补充说。这些特殊的肌肉难以控制，只有少数人才能做到这一点。例如，当有人感到不屑一顾时不能确定他们的眉毛总是向下撇。

　　美国人保罗·埃克曼教授试图建立这样的规则，他曾创建了一个描述表达每个情感时面部变化的数据库，人的脸部可以做出43种截然不同的叫做"行动单位"的肌肉运动。这些"行动单位"能组合成超过l o000种的可见的面部形态。埃克曼教授已经编写出面部肌肉的运动模式来代表每个情感。

　　德国科研人员发现了一种将空气中的水气自动转化为饮用水的方法。该研究小组的组长Siegfried Egner说："我们开发的这套工序完全基于诸如太阳热能收集器和光生伏打电池的可再生能源。这使得该方法在能量方面完全自主，即使在没有电力基础设施的地方仍可起到作用。"这套工序的原理如下：吸湿盐水--能够吸收湿气的盐水溶液--沿着一塔状结构容器下流时在空气中吸收水分。水被吸到地下几米深的一个真空水箱中。来自于太阳能收集器的能量将盐水加热，这样盐水就将会稀释它所吸收的水。

　　在真空环境中，液体的沸点要比在正常大气压下的要低。这一效果可以在山区了解到：由于山上的大气压比山谷的要低，因此水的沸点明显低于100摄氏度。这些蒸发了的、不是盐水的水被浓缩后沿着一支充满蒸汽的管子慢慢向下流。水柱的重力持续制造真空状态，所以不需要真空泵。经过再次浓缩的盐水会沿着塔状物再次向下流去吸收空气中的水分。

　　Egnerr说："这一理念适用于各类使用水的人群。单人房以及可以为整个宾馆供应水的工厂都成为可能。"这套系统的两个构件--空气水汽吸收器和真空蒸汽机的样机已经制造出来。科研人员也已经在实验室范围内测试了它们相互作用的效果。研究者们计划在下一步的研究中开发出一套用于展示的设备。
