职称英语理工类新增
写在最前面的关于30分题+15分1. +表示A级文章；*表示B即文章；其他为C级文章，考哪一级就看哪一级的内容，别的级别的题目完全不用看。
2. 每个级别新增阅读理解2篇完型填空2篇（今年以前完形填空只新增一篇），考试的时候，这两篇阅读理解必考一篇，文章完全一样，但是问题及答案不一定完全一样，所以仅仅记住答案是不可靠的，一定要结合后面的翻译把这篇文章看懂。
那么这里5道题目15分必定能拿到。
然后完型填空，先说今年以前，只新增一篇完型填空，这篇完型填空必考，只是留空的位置不会完全一样，大约有40%左右的留空位置是一样，所以光背答案是没得用的，一定要把文章看熟。
当然今年由于每个级别新增了2篇完型填空，那么考试的时候肯定也是2选1考一篇。
这里15道题15分也很容易能拿到。
3. 词汇有15道题，替换同义词，找本字典翻翻，这15分也不难，至少12分能拿到吧。
其他的题能拿多少分就看各位的英语底子了。
做最坏的打算，剩下的题目还有55分，按瞎蒙25%的概率能拿到13.75分，加上前面的45分大约也有58分左右，所以要完全靠瞎蒙的朋友考试前多扶扶老奶奶过马路，多积累点人品吧。
4. 以上只是投机取巧的方法，各位有时间的话还是花点时间复习下，但是考前一定要把新增的题目掌握好，就算英语底子好的朋友也起码可以节约不少考试时间。
5. 本人职称英语A\B\C级都是这样考过的，每年的规律都是一样的。
从客观角度说，每年的职称英语考试书都不便宜，新增的内容也不多，如果新增的东西里面没有价值，那么那本书还有谁买？那本书可是考试中心出的，亲！最后，祝大家考试顺利！2012年职称英语理工类新增文章阅读理解（6篇）……………………3页第六篇 Making Light of1 Sleep第十九篇 Graphene's Superstrength1*第三＋八篇 "Life Form Found" on Saturn's Titan*第四十篇 Teaching Math, Teaching Anxiety+第四＋五篇 Teaching Math, Teaching Anxiety+第四十六篇Ants Have Big Impact on Environment as "Ecosystem Engineers"完形填空（6篇）……………………20页第三篇 Germs on Banknotes第十篇 Chicken Soup for the Soul：Comfort Food Fights Loneliness *第十一篇 Climate Change Poses Major Risks for Unprepared Cities*第十二篇 Free Statins With Fast Food Could Neutralize Heart Risk+第十三篇 Solar Power without Solar Cells+第十五篇“Liquefaction” Key to Much of Japanese Earthquake Damage注：1、+表示A级文章；*表示B即文章；其他为C级文章；2、阅读理解，请参见第3页；完形填空，请参见第20页；3、2012年词汇部分与2011年教材相比未作任何变化。

Similar to your bedside alarm clock，your internal clock2 runs on a 24-hour cycle. This cycle，called a circadian rhythm，helps control whenyou wake，when you eat and when you sleep.Somewhere around puberty，something happens in the timing of the biological clock. Theclock pushes forward，so adolescents and teenagers are unable to fall asleep as early as they used to. When your mother tells you it's time for bed，your body may be pushing you to stay up3 for several hours more. And the light coming from your computer screen or TV could be pushing you to stay up even later.This shift4 is natural for teenagers. But staying up very late and sleeping late can get your body's clock out of sync with the cycle of light and dark5. It can also make it hard to get out of bed in the morning and may bring other problems，too. Teenagers are put in a kind of a gray cloud6when they don't get enough sleep，says Mary Carskadon，a sleep researcher at Brown University in Providence，RI7 .It affects their mood and their ability to think and learn.But just like your alarm clock，your internal clock can be reset. In fact，it automatically resetsitself every day. How? By using the light it gets through your eyes.Scientists have known for a long time that the light of day and the dark of night play important roles in setting our internal clocks. For years，researchers thought that the signals that synchronize the body's clock8were handled through the same pathways that we use to see.But recent discoveries show that the human eye has two separate light-sensingsystems. One system allows us to see. The second system tells our body whether it's day or night.词汇：circadian/s3:'keidiən/ adj. 昼夜节奏的，生理节奏的adolescent/ædəu'lesənt/ n．青少年；adj．青少年的puberty/ 'pju:bəti/ n．发育；青春期sync/siŋk/ n. （口语）同步；和谐，协调synchronize/'siŋkrənaiz / V.（使）同时发生；（使）同步注释：1.make light of ：轻视，不在乎。

Just about every kid in the US has heard this from a parent or grandparent. Often，it's accompanied by an appeal:" Just think about those starving orphans in Africa!" Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of staying "clean the plate", perhaps we should save some food for tomorrow.According to news reports, US restaurants are partly to blame for the growing bellies. A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.Barbara Rolls, a nutrition professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline began to expand.Health experts have tried to get many restaurants to serve smaller portions. Now, apparently，some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believe restaurants serve portions that are too large;23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can't afford fine dining still prefer large portions. Seventy percent of those earning at least $150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25,000 want smaller.It's not that working class Americans don't want to eat healthy. It's just that，after long hours at low-paying jobs，getting less on their plate hardly seems like a good deal. They live from paycheck to paycheck ，happy to save a little money for next year's Christmas presents.词汇:orphan /''?:f?n] / n.孤儿belly /'beli/ n.肚子3nutrition / nju:'tri??n / n.营养waistline / 'weistlain / n.腰围paycheck / 'pei't?ek / n.薪金支票注释:1.

2011年职称英语完型填空新增文章译文---理工类运动的年轻人智商更高理A瑞典歌德堡大学健康科学研究院和该校校医院的一项最新研究表明，身体健康的年轻人智商更高，进入大学学习的可能性也更高。
研究结果发表在美国国家科学院学报上。
这项研究的取样样本是1950-1976年入伍的120万新兵。
这些新兵报到时接受了体能测试和智能测试，研究人员对这两类测试数据进行了分析。
研究表明，健康的体能和优秀的只能测试结果之间的联系很明显。
最突出的就是科学思维和语言理解能力与身体健康有关。
但是智商测试结果中只是健康在起作用，而与力量无关。
“身体健康是指，一个人心肺功能好，能将充分的氧气源源不断地输入给大脑，”瑞典歌德堡大学健康科学研究院教授和瑞典歌德堡大学健康科学研究院校医院首席内科医师Michael Nilsson如是说，“也许这就是为什么智商测试结果与健康之间存在明显联系，而与肌肉力量无关的原因之一。
我们还发现生长因子也很重要。
”通过研究双胞胎的数据，研究人员可以得出结论，智商差异来自后天的环境因素而不是先天的基因，身体健康，智商越高。
“我们还发现，在15-18岁之间加强身体锻炼的青少年往往认知能力也较强，”瑞典歌德堡大学健康科学研究院研究员，Aby健康中心医师Maria Aberg说，“倘若情况果然如此，那么体育应成为学校中重要的一门学科，而且如果我们想要学好数学和其他理论学科，体育课是非常有必要的。
”研究人员还将新兵服兵役入伍报到时的体格测试和智商测试的结果与他们后来生活中的社会经济地位进行了比较。
那些18岁时身体健康的人学历更高，很多都能胜任高要求的工作。
吸烟会加重青少年的抑郁情绪理B有些青少年可能会一口接一口地吸烟来消除抑郁，进行所谓的“自我治疗”。
然而加拿大Toronto和Montreal大学的科学家却发现，事实上，吸烟会加重某些青少年的抑郁情绪。
“这项研究是检验吸烟是否可以给青少年带来精神欢愉的几项研究之一，”首席研究员Michael Chaiton如是说，他是Toronto大学Ontario烟草研究组织的助理研究员，“尽管吸烟能在短时间能起到自我治疗的作用，能振奋精神，但根据青少年自我报告的情况，我们发现，从长远看，吸烟的青少年往往有更多的抑郁症状。

These stories fall into three general categories: autobiography, memoir, and biography.An autobiography is the story of a person's life written by himself or herself. Often it begins with the person's earliest recollections and ends in the present. Autobiography writers may not be entirely objective in the way they present themselves. However, they offer the reader a good look at the way they are and what makes them that way. People as diverse as Benjarmin Franklin and Helen Keller have written autobiographies. 1Other writers, such as James Joyce，have written thinly fictionalized accounts of their lives. These are not autobiographies，but they are very close to it.Memoirs, strictly speaking, are autobiographical accounts that focus as much on the events of the times as on the life of the author. 2Memoir writers typically use these events as backdrops for their lives. They describe them in detail and discuss their importance. Recently，though，the term memoir seems to be becoming interchangeab1e with autobiography. A memoir nowadays may or may not deal with the outside world.Biographies are factual accounts of someone else's life. In many senses，these may be the hardest of the three types to write. Autobiography writers know the events they write about because they lived them. But biography writers have to gather information from as many different sources as possible. Then they have to decide which facts to include. Their goal is to present a balanced picture of a person，not one that is overly positive or too critical. A fair well-presented biography may take years to research and write.词汇：backdrop /'b k,dr?p/ n. 背景interchangeable /int? 't?end??bl/ adj. 可转换的注释：1. People as diverse as Benjamin Franklin and Helen Keller have written autobiographies. 就像本杰明富兰克林和海伦凯勒一样，各种各样的人们已经写了自传。

2012年全国职称英语考试试题完形填空+第十三篇Solar Power without Solar CellsA dramatic and surprising magnetic effect of light discovered by University of Michigan1researchers could lead to solar power without traditional semiconductor-based solar cells.The researchers found a way to make an "optical 1 ," said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics.Light has electric and magnetic components. Until now, scientists thought the 2 of the magnetic field were so weak that they could be ignored. What Rand and his colleagues found is that at the right intensity, when light is traveling through a material that does not conduct electricity, the light field can generate magnetic effects that are 100 million times stronger than 3 expected. 4 these circumstances, the magnetic effects develop strength equivalent to a strong electric effect."This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge separation," Rand said. "In solar cells, the 5goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load2. Instead of the light being absorbed, energy is stored in the magnetic moment3. Intense magnetization can be induced by intense light and then it is ultimately capable of providing a capacitive power 6."What makes this possible is a previously undetected brand of "optical rectification4," says William Fisher, a doctoral student5 in applied physics. In traditional optical rectification, light's electric field causes a charge separation, or a pulling 7 of the positive and negative charges6 in a material. This sets up a voltage, similar to 8 in a battery.Rand and Fisher found that under the right circumstances and in right types of materials, the light's magnetic field can also create optical rectification. The light must be shone through7a 9 that does not 10 electricity, such as glass. And it must be focused to an intensity of 10 million watts per square centimeter8. Sunlight isn't this intense on its own, but new materials are being sought that would work at lower intensities, Fisher said."In our most recent paper, we show that incoherent light9 like sunlight is theoretically almost as. 11 in是美国名列前茅的公立大学，拥有优良的师资和顶尖的商学院、法学院、医学院和工学院。

Some tourists go to see battlefields or religious shrines. Others are looking for culture, or simply want to have their pictures taken in front of famous places.1. The writer seems to imply that Europeans travel mostly for the reason that they wish to escape from the cold, dark and rainy days back at home.2. In paragraph 2, cities like London, Copenhagen, and Amsterdam are mentioned to show that they are not good cities in terms of geography and climate.3. According to the passage, which of the following countries attracts more tourists than the others? Spain.4.

According to the passage, which of the following factors might spoil the tourists' fun at Mediterranean resorts and beaches? Rainy weather .第八篇 The Changing Middle Class 变化中的中产阶级The United States perceives itself to be a middle-class nation. However，middle class is not a real designation，nor does it carry privileges. It is more of a perception，which probably was as true as it ever could be right after World War II.1. The information in this passage deals with a social and economic group.2. A common middle class value is that the family is very important.3. ln the years after World War II，the middle class could be defined as prosperous and optimistic.4. The phrase “In other words" in the first paragraph means that the following statement is a restatement of the previous idea.5. The word collectively means as a group.第九篇Single-parent Kids Do Best 单亲幼儿最出色Single mums are better at raising their kids than two parents - at least in the bird world.

David, 64, lives in a three-bedroomed flat right at the top of the Byward Tower, one of the gatehouses. " From our bedroom we have a marvellous view of Tower Bridge and the Thames, " says David.The Tower of London is famous for its ravens, the large black birds which have lived there for over three centuries. David was immediately fascinated by the birds and when he was offered the post of Raven Master eight years ago he had no hesitation in accepting it. "The birds have now become my life and I'm always aware of the fact that I am maintaining a tradition. The legend says that if the ravens leave the Tower, England will fall to enemies, and it's my job to make sure this doesn't happen!"David devotes about four hours a day to the care of the ravens. He has grown to love them and the fact that he lives right next to them is ideal. "I can keep a close eye on them all the time, and not just when I'm working." At first, David's wife Mo was not keen on the idea of life in the Tower, but she too will be sad to leave when he retires next year. "When we look out of our windows, we see history all around us, and we are taking it in and storing it up for our future memories."第二篇 A Lucky Break 幸运的骨折Actor Antonio Banderas is used to breaking bones, and it always seems to happen when he's doing sport. In the film Play it to the Bone he plays the part of a middleweight boxer alongside Woody Harrelson. During the making of the film Harrelson kept complaining that the fight scenes weren't very convincing, so one day he suggested that he and Banderas should have a fight for real. The Spanish actor wasn't keen on the idea at first, but he was eventually persuaded by his co-star to put on his gloves and climb into the boxing ring. However, when he realized how seriously his opponent was taking it all, he began to regret his decision to fight. And then in the third round, Harrelson hit Banderas so hard in the face that he actually broke his nose. His wife, actress Melanie Griffith, was furious that he had been playing "silly macho games". "She was right," confesses Banderas, "and I was a fool to take a risk like that in the middle of a movie."He was reminded of the time he broke his leg during a football match in his native Malaga. He had always dreamed of becoming a soccer star, of performing in front of a big crowd, but doctors told him his playing days were probably over. "That's when I decided to take up acting; I saw it as another way of performing, and achieving recognition. What happened to me on that football pitch was, you might say, my first lucky break."第三篇Global Warming 全球变暖Few people now question the reality of global warming and its effects on the world's climate. Many scientists put the blame for recent natural disasters on the increase in the world's temperatures and are convinced that, more than ever before, the Earth is at risk from the forces of the wind, rain and sun. According to them, global warming is making extreme weather events, such as hurricanes and droughts, even more severe and causing sea levels all around the world to rise .Environmental groups are putting pressure on governments to take action to reduce the amount of carbon dioxide which is given off by factories and power plants, thus attacking the problem at its source. They are in favour of more money being spent on research into solar, wind and wave energy devices, which could then replace existing power stations.Some scientists, however believe that even if we stopped releasing carbon dioxide and other gases into the atmosphere tomorrow, we would have to wait several hundred years to notice the results. Global warming, it seems, is here to stay.第四篇 A Success Story 一个成功的故事At 19, Ben Way is already a millionaire, and one of a growing number of teenagers who have made their fortune through the Internet.

了“Common Questions about Dreams”这篇补全短文，这是综合C,理工C以及卫生C的新增文章，供大家学习。
Common Questions about DreamsDoes everyone dream?Yes. Research shows that we all dream. We have our most vivid dreams during a type of sleep called Rapid Eye Movement (REM) sleep. During REM sleep, the brain is very active. The eyes move quickly back and forth1 under the lids, and the large muscles of the body are relaxed. REM sleep ours every 90-100 minutes, three to four times a night, and it lasts longer as the night goes on. 1 We dream at other times during the night, too, but those dreams are less vivid.Do people remember their dreams?A few people remember their dreams. However, most people forget nearly everything that happened during the night —dreams, thoughts, and the short periods of time when they were awake. 2 It seems that the memory of the dream is not totally lost, but for some reason it is very hard to bring itback2. If you want to remember your dream，the best thing to do is to write it down as soon as you wake up.Are dreams in color?Most dreams are in color. However, people may not be aware of it for two reasons ：They don’t usually remember the d etails of their dreams, or they don’t notice the color because it is such a natural part of our lives. 3Do dreams have meaning?Scientists continue to debate this issue.3 4 Some people use dreams to help them learn more about their feelings, thoughts, behavior, motives, and values. Others find that dreams can help them solve problems. It’s also true that artists, writers, and scientists often get creative ideas from dreams.How can I learn to understand my dreams?The most important thing to remember is that your dreams are personal. The people, actions, and situations in your dreams reflect your experience, your thoughts, and your feelings. Some dream experts believe that there are certain types of dreams that many people have，even if they e from different cultures or time periods. Usually, however, the same dream will have different meanings for different people. For example, an elephant in a dream may mean one thing to a zookeeper and something very different to a child whosefavorite toy is a stuffed elephant. 5 Then look for links between your dreams and what is happening in your daily life. If you think hard and you are patient, perhaps the meaning of your dreams will bee clearer to you.词汇：vivid /'vivid/ adj. 清晰的，生动的，逼真的lid /lid/ n. 眼睑(=eyelid)motive /m?utiv/n. 动机stuffed /st?ft/adj. 填充的，塞满了的注释：1. back and forth：来回地，反复地。

The first comprehensive study on the nation's oral health，released recently by the Office of the U.S. Surgeon General，calls dental and oral disea ses a “silent epidemic (流行病)，” even in children. The report states that more than 51 million school hours are lost each year to dental-related illness. In fact，a recent study pointed to dental care as the most common unmet health need among American children.To help counter this，the American Academy of Periodontology (牙周病学)(AAP)is launching an effort to educate children and parents about the prevention of dental diseases in children.“This is important because oral problems can impact self-esteem for children and lead to problems of eating，speaking and attending to learning，” said Michael McGuire，president of the AAP.Common dental problems seen in children are cavities (龋洞)and gingivitis (龈牙)，which are found in the majority of U.S. children. “When these pr oblems are not caught early and treated，they can develop into more severe problems and cause unnecessary suffering，” said McGuire “However，much of the time，oral problems are avoidable problems.”In the Rio Grande Valley in Texas，a group of more than 120 dentists volunteers to deliver dental care to thousands of low-income children each year with its Mobile Dental Unit that travels from school to school.“According to the Surgeon General's Report，about 37 percent of children have not had a dental visit before starting school，” said McGuire. “When children don't see dentists theymiss the opportunity to have problems caught early before they develop into larger，more expensive problems to treat，and parents miss the opportunity to learn how to promote good oral habits in their children.”16 Only in February should attention be paid to children's oral healthA RightB WrongC Not mentioned17 Dental and oral diseases are common in both adults and childrenA RightB WrongC Not mentioned18 Boys miss more school hours each year due to dental-related illnessA RightB WrongC Not mentioned19 Oral problems in children can develop into more severe problems.A RightB WrongC Not mentioned20 Oral problems can not be avoided in any wayA RightB WrongC Not mentioned21 The low-income children are very grateful to the dentists.A RightB WrongC Not mentioned22 Some children have never seen a dentist before starting school.A RightB WrongC Not mentioned第3部分：概括大意与完成句子(第23～30题，每题1分，共8分)下面的短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第1～4段每段1选择个最佳标题;(2)第27～30题要求从所给的6个选项中为每个句子确定1个最佳选项。

They may use 2 currencies, but these countries, and probably all countries, still have one thing in common1: Germs on the banknotes.Scientists have been studying the germs on money for well over2 100 years. At the turn of the 20th 3 , some researchers began to suspect that germs living on money could spread disease.Most studies of germy money have looked at the germs on the currency 4 one country. In a new study, Frank Vriesekoop3 and other researchers compared the germ populations found on bills of different 5 .Vriesekoop3 is a microbiologist at the University of Ballarat in Australia4. He led the study, which compared the germ populations found on money 6 from 10 nations. The scientists studied 1,280 banknotes in total; all came from places where people buy food, like supermarkets street vendors and cafes, 7 those businesses often rely on cash.Overall, the Australian dollars hosted the fewest live bacteria ---- no more than 10 per square centimeter. Chinese yuan had the most ---- about 100 per square centimeter. Most of the germs on money probably would not cause harm.What we call “paper” money usually isn't made from paper. The U. S. dollar, for example, is printed on fabric that is mostly 8 .Different countries may use different 9 to print their money. Some of the currencies studied by Vriesekoop and his 10 such as the American dollar were made from cotton. Others were made from polymers.The three 11 with the lowest numbers of bacteria were all printed on polymers. They included the Australian dollar, the New Zealand dollar and someMexican pesos.The other currencies were printed on fabric made 12 of cotton. Fewer germs lived on the polymer notes. This connection suggests that 13 have a harder time staying alive on polymer surfaces. Scientists need to do more studies to understand how germs live on money-----and whether or not we need to be concerned. Vnesekoop is now starting a study that will 14 the amounts of time bacteria can stay alive on different types of bills.Whatever Vriesekoop finds, the fact remains: Paper money harbors germs We should wash our 15 after touching it; after all5, you never know where your money 's been.

2012年职称英语综合类A级阅读理解新增文章
2012 年职称英语综合类新增文章—阅读理解To Have and Have Not It had been boring hanging about the hotel all afternoon. The road crew were playing a game with dollar notes. Folding them into small planes to see whose would fly the furthest.I having nothing better to do，I joined in and won five，and then took the opportunity to escape with my profit. Despite the evil-looking clouds，I had to get out for a while.I headed for a shop on the other side of the street. Unlike the others，it didn't have a sign shouting its name and business，and instead of the usual impersonal modern lighting，there was an appealing glow inside. Strangely nothing was displayed in the window. Not put off by this，I went inside. It took my breath away. I didn't know where to look, where to start. On one wall there hung three hand-stitched American quilts that were in such wonderful condition they might have been newly-made. I came across tin toys and antique furniture, and on the wall in front of me, a 1957 Stratocaster guitar , also in excellent condition. A card pushed between the strings said $50. I ran my hand along a long shelf of records, reading their titles. And there was more... ―Can I help you？‖She startled me. I hadn't even seen the woman behind the counter come in. The way she looked at me, so directly and with such power. It was a look of such intensity that for a moment I felt as if I were wrapped in some kind of magnetic or electrical field.I found it hard to take and almost turned away. But though it was uncomfortable. I was fascinated by the experience of her looking straight into me, and by the feeling that I was neither a stranger, nor strange, to her. Besides amusement her expression showed sympathy. It was impossible to tell her age；she reminded me faintly of my grandmother because, although her eyes were friendly, I could see that she was not a woman to fall out with. I spoke at last. 'I was just looking really,' I said, though secretly wondering how much of the stuff I could cram into the bus. Thewoman turned away and went at once towards a back room, indicating that I should follow her. But it in no way lived up to the first room. The light made me feel peculiar, too. It came from an oil lamp that was hung from the centre of the ceiling and created huge shadows over everything. There were no rare electric guitars, no old necklaces, no hand-painted boxes with delicate flowers. It was also obvious that it must have taken years, decades, to collect so much rubbish, so many old documents arid papers. I noticed some old books, whose gold lettering had faded, making their titles impossible to read. 'They look interesting,' I said, with some hesitation. 'To be able to understand that kind of writing you must first have had a similar experience,' she said clearly. She noted the confused look on my face, but didn't add anything. She reached up for a small book which she handed to me. 'This is the best book I can give you at the moment,' she laughed. ―If you use it.‖I opened the book to find it full. or rather empty, with blank white pages, but paid her the few dollars she asked for it, becoming embarrassed when I realised the notes were still folded into little paper planes.

*第三＋八篇"Life Form Found" on Saturn's TitanScientists say they have discovered hints of alien life1 on the Saturn's moon2. The discovery of a sort of life was announced after researchers at the US space agency,NASA3,analyzed data from spacecraft Cassini4,which pointed to,the existence of methane-based form of life on Saturn's biggest moon.Scientists have reportedly discovered clues showing primitive alien beings are"breathing" in Titan's dense atmosphere filled with hydrogen.They argue that hydrogen gets absorbed before hitting Titan's planet-like surface covered with methane lakes and rivers. This,they say,points to the existence of some"bugs"5 consuming the hydrogen at the surface of the moon less than half the size of the Earth."We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan,similar to the way we consume oxygen on Earth,"says NASA scientist Chris McKay."If these signs do turn out to be a sign of life,it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth."To date,scientists have not yet detected this form of life anywhere,though there are liquid- water-based microorganisms on Earth that grow well on methane or produce it as a waste product. On Titan, where temperatures are around 90 Kelvin6(minus 290 degrees Farenheit),amethanebased organism would have to use a substance that is liquid as its medium for living processes, but not water itself. Water is frozen solid on Titan's surface and much too cold to support life as we know it.Scientists had expected the Sun's interactions with chemicals in the atmosphere to produce a coating of acetylene on Titan's surface. But Cassini detected no acetylene on the surface.The absence of detectable acetylene on the Titan's surface can very well have a non-biological explanation,said Mark Allen,a principal investigator7 of the NASA Titan team."Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed,"Allen said. "We have a lot of work to do to rule out8 possible non-biological explanations. It is more likely that a chemical process,without biology,can explain these results."词汇：Saturn /'sætən/ n．土星methane/'mi:θein/ n．甲烷，沼气Titan/'taitən/ n．土卫六acetylene/ə'setili:n/ n．乙炔alien/'eiljən/ n．外星人；adj．外星球的；相异的conservatism/kən'sʒ:vətizəm/ n．保守主义,守旧注释：1.hints of alien life：外星生命迹象。
2.the Saturn's moon：指土卫六（Titan) 。
土卫六又称泰坦星，是土星卫星中最大的一颗。
3.NASA：美国国家航空航天局的缩写，全称是：National Aeronautics and SpaceAdministration。
4.spacecraft Cassini：卡西尼号探测器，以出生于意大利的法国天文学家卡西尼的名字命名，其任务是环绕土星飞行，对土星及其大气、光环、卫星和磁场进行深人考察。
1997 年10 月15日，重六吨的“卡西尼”号星际探测器被发射飞往土星的轨道。
这是上世纪发射的最后一艘行星际探测的大飞船。
“卡西尼”号用了将近七年时间，在2004 年7月1日飞达土星轨道。
5.bugs：微生物。
非正式口语表达，所以使用了引号。
6.Kelvin：可翻译成“绝对温度”。
Kelvin Scale ，绝对温标，开氏温标，是由Kelvin 勋爵于19世纪中叶发明的温度计量方法，其零度相当于摄氏一273. 15" C ，被认为是宇宙中最低温度。
这种温度计量方法多为科学家使用。
