中南大学博士研究生英语考试真题全文共6篇示例,供读者参考篇1My Big Brother's Really Hard TestHi! My name is Lily and I'm 8 years old. I'm in 3rd grade at Sunshine Elementary School. My big brother David is 24 and he's trying to get into a PhD program at a university called University of Central South in China. It's a really good school for studying science and engineering.Last weekend, David had to take this giant exam called the PhD entrance exam. It looked super duper hard! The exam had sections on listening, reading, writing, and translating between Chinese and English. David studied like crazy for weeks before the test.For the listening part, David had to listen to recordings in English of lectures and conversations. Then he had to answer questions about the main ideas and details he heard. Some of the recordings were about really complicated topics like quantum physics and bioengineering. I tried listening to one of David's practice recordings and it was all just篇2The Big Test for the Really Smart StudentsMy big sister is so smart! She is in university studying to be a doctor or scientist or something. She has to take all sorts of really hard tests. I don't know how she does it. Tests are the worst!The other day, she was telling me and my parents about this huge English test she has to take soon. It's called the PhD English Exam or something like that. PhD must mean "Pretty Hard Doozy" because that's what it sounds like to me!She said it's a requirement for all the students working on their highest degree thingy, like a master's but even higher. I can't imagine having to take a test that big after being in school for so many years already. No thank you!My sister explained that the test has different sections to show you really know English well. There's a listening part where you hear conversations or talks and have to answer questions about the main ideas and details.Then there's a reading section with long passages on serious topics. You need to understand the passages and answerquestions that check if you truly comprehended the main points, structures, and implied meanings. It sounds super hard to me.There are also writing tasks where you have to write essays and summarize information from readings or lectures. My sister said you get judged on your vocabulary, grammar, organization, and how well you support your ideas. Writing has always been one of my biggest struggles in school.But the part that sounds most scary to me is the speaking section! Can you imagine having to speak English in an official test environment? My sister described having to give speeches and respond to questions, all while being recorded. I'd be shaking like a tiny mouse!On top of those sections, there are parts that test your knowledge of grammar rules, sentence structures, and academic vocabulary. My sister has been studying reference books full of terms I've never even heard of. I don't know how she keeps it all straight in her brilliant brain.From what she's told me, it's a marathon test that takes hours to complete. You need incredible stamina along with your language skills. My mom jokes that they should give test-takers little treadmills to walk on so they don't fall asleep!I admire my sister for tackling such an immense challenge. She has always been driven and never shies away from hard work. Still, thinking about that exam makes my head spin. I don't know if the reward of getting credit for the test and moving on in the program is worth all that pressure and difficulty.Then again, I'm just a kid. My biggest tests are my weekly spelling quizzes and hoping I bubbled in the right answers on my math homework. For university students like my big sis who want to earn the highest degrees, conquering the PhD English Exam is just par for the course.I'm rooting for her because I know she's got the brainpower and dedication to knock it out of the park. But you couldn't pay me a million dollars to walk a mile in her shoes! Maybe when I'm older, I'll appreciate academic challenges more. For now, I'll stick to my times tables and thank my lucky stars I don't have to face the "Pretty Hard Doozy" of an English test anytime soon.Those university-level assignments sound harder than climbing Mount Everest! I'll leave the extreme scholarly feats to my sister the super-achiever. I'm sticking to snack times, recess, and hopefully passing third grade. Wish my poor, overstressed sister lots of luck because she's gonna need it!篇3My Big Brother's Hard English TestMy big brother is so smart! He's in university studying really difficult things to become a doctor. But before he can get his special doctor degree, he has to pass this crazy hard English test. It's called the Doctoral English Exam and it's given at his school, Central South University.I'm only 10 years old, but I've heard my brother talking about how stressful this test is. He's been studying English reallyreally hard for months! He has to know all sorts of big vocabulary words that I've never even heard of. And he has to be able to read papers and books from scientists and professors and understand everything they're saying. It's a lot harder than the simple English books I read in school!My brother lets me look through some of his English study materials sometimes. There are chapters upon chapters of scientific words about math, chemistry, biology, and everything else. Reading it makes my head spin! How is anyone supposed to learn the meaning of words like "biochemical" or "thermodynamic"? They sound like spells from Harry Potter! Mybrother has entire lists of these crazy vocabulary words that he has to memorize.Then there are the practice tests he has to take. They give him long passages from research papers and science journals, and he has to answer all of these complicated questions about the main ideas, the evidence used, the author's views and assumptions, and more. He shows me the reading passages sometimes and I can't make any sense of them at all! It's like they're written in code.And that's not even the hardest part of the exam! My brother also has to write a paper in perfect English, using proper academic language and formating. He has been practicing his writing over and over, making sure every single word is used accurately. Mom and dad proofread his practice essays but they always find tons of little mistakes. You can't have any errors at all on this big important test!The exam also has a listening section where my brother has to understand recordings of lectures and conversations between professors. He struggles a lot with that part because the speakers use such advanced vocabulary and speak really fast with complicated sentence structures. My brother makes me read thelistening transcripts out loud to him sometimes to practice, but I always stumble over the words and can't read smoothly.I really feel bad for my big brother. He has been working himself to the bone studying for this insane English test. I don't know how he keeps it all straight in his head! Every night he's hunched over his desk with his face buried in books and notebooks, writing and re-writing practice essays and vocabulary lists. When he's not studying, he looks exhausted.This doctoral English exam is definitely no joke. I can't even imagine having to know that much English when I'm older! Part of me is jealous of how smart and hard-working my brother is. But another part of me is really glad that I'm just a kid and don't have to worry about anything as difficult as this test anytime soon. I'll just be happy learning simple English reading and writing in elementary school for now. My brother is the real English superhero in our family!Everyone has been cheering him on as he gets closer to his test day. We're all rooting for him and know he's going to do awesome. He's been preparing for so long, it would be a shame for all his effort to go to waste. I really look up to him for being able to tackle something as challenging as this English exam. He's going to make our family so proud when he passes!篇4My Big Sister's Big TestHi! My name is Lily and I'm 8 years old. I love playing outside, reading books, and eating ice cream. But today I want to tell you about something really important that happened to my big sister Amy.Amy is 24 years old and she just finished her master's degree in chemistry at Central South University. That's a really good school in Changsha, which is a big city in China. After getting her master's, Amy decided she wanted to continue studying and get her PhD, which is the highest degree you can get!To get into the PhD program at Central South University, Amy had to take a really difficult exam called the entrance exam for PhD candidates. It had sections testing her English ability, her knowledge of chemistry, and her research skills. Amy studied super hard for months to prepare.The exam was last Saturday and Amy was really nervous leading up to it. The night before, she laid out her pencils, erasers, calculator, water bottle, and snacks on the kitchen table. She wanted to make sure she was totally ready. I remember her pacing back and forth, mumbling chemistry equations under herbreath. My parents kept telling her "You've got this Amy! You're so prepared!"On the morning of the exam, we all got up really early. My dad made Amy's favorite breakfast - an omelet with peppers, onions, and cheese. Amy's hands were shaking as she forced a few bites down. You could tell she had butterflies doingloop-de-loops in her stomach.The exam was held at the Central South University chemistry building, which is this huge fancy place with tons of labs. As we pulled up, I saw hundreds of people streaming inside holding pencil cases and water bottles. They all looked just as nervous as Amy.My mom, dad, and I went with Amy to the registration desk to get her testing room assignment. The lady working there was very stern looking. "Candidate number 4521, testing room 327B," she barked at Amy. Amy gulped and gave us a scared look. We pulled her into a big family hug. "You're going to do great! We love you!" my mom whispered.Then it was time for Amy to go in. She straightened her shoulders, took a deep breath, and strode towards the testing rooms looking determined. We waited outside for what felt like forever!Finally, after six looooong hours, Amy emerged from the building. She looked exhausted but had a little smile on her face. We ran over and smothered her with hugs and kisses. "How did it go? How did it go?" we all shouted. Amy laughed, "It was so hard! That English reading section almost killed me. But I feel like I did pretty well overall!"We went out for Amy's favorite dumplings that night to celebrate her pushing through the big test. She had to wait a few weeks to get her results, but she felt good about it. Sure enough, a few weeks later Amy got the great news that she passed and was admitted to the PhD program! We were all so proud.Now Amy is hard at work on her PhD research. She spends many late nights in the lab running experiments and analyzing data. Sometimes she comes home looking like a zombie from being so tired. But she's living her dream of becoming a chemical researcher.I hope I can be as hard-working and dedicated as my big sister Amy when I grow up. She inspires me to follow my passions and never give up, no matter how difficult the challenge. I'm so proud of her for passing that big entrance exam through all her preparation and perseverance. Maybe I'll be a PhD student at Central South University too someday!篇5The Big Grown-Up TestHi! My name is Lily and I'm 8 years old. I have to tell you about this really crazy thing that happened to me last week. It was the craziest, most bonkers thing ever!You see, my big sister Mei is a super smart PhD student at Central South University. She's getting her super duper genius degree in microbiology, which is the study of tiny little germs that you can't even see unless you have a really powerful microscope. Isn't that crazy?Anyway, last week Mei had to take this gigantic, huge, enormo test called the "PhD English Examination." It's supposed to be like the most difficult English test in the whole world for people trying to get their PhD. Mei studied super hard for weeks and weeks, reading big heavy books and making notecards and everything.She told me the test was going to be four whole hours long! Can you imagine? I can't even sit still for the one-hour monthly tests we take at my elementary school. Four hours of just reading and writing in English sounds like literal torture to me. But Iguess if you want to get a PhD, you have to be a super genius and take tests like that.The morning of the test, Mei was very nervous. Her hands were shaking as she put on her lucky hair ribbon and packed her pencils and eraser in her backpack. I thought it was funny that a grown-up still used a backpack, but I guess everyone needs somewhere to put their stuff."Don't worry, Mei!" I told her. "You're going to ace this test because you're the smartest person I know after Albert Einstein and Marie Curie."Mei gave me a big hug. "Thanks, squirt. Wish me luck!" And then she headed off to the university to face her big grown-up test.Well, four hours slowly ticked by. Four whole hours! I played outside, had a snack, took a tiny nap, and played some more, and Mei still wasn't home yet. I was starting to get a little worried about her.Finally, after what felt like a million years, Mei came trudging through the door. She looked like a zombie that had been through a tornado! Her hair was sticking up in all directions, her shirt was untucked, and she had huge bags under her eyes."Mei! Are you okay?" I rushed over to see if she needed a glass of water or a nap on the couch."I'm fine, Lily," Mei said in a croaky voice. "Just really, really tired. That test was...intense."Then she told me all about the different sections on the test. There was reading, where you had to read a billion passages about things like economics and biochemistry and answer mega hard comprehension questions.Then there was writing, where you had to write a gorillion word essay arguing whether smoking should be banned in public parks or whatever. Can you imagine? A gorillion words in four hours? My hand would fall off after writing that much!And those were just the start. Mei also had sections testing her listening skills, her verbal skills, her translation abilities, and even using English to present scientific research! It sounded positively grueling. No wonder Mei looked like a wet dishrag when she got home."So...how did it go?" I asked once Mei had gulped down a big glass of water. "Did you ace it and make me and Mom and Dad proud?"Mei shrugged her shoulders. "I don't know, Lily. I really don't know if I passed or not. It was just...so hard. I felt really prepared going in, but there were some sections and questions that completely stumped me. We don't get the results back for a couple months."For the next few months, Mei was a nervous wreck wondering if she had done well enough on the test. She kept imagining worst case scenarios where she failed and had tore-take the whole thing over again next year. I felt really bad for her.Finally, the long-awaited day arrived when Mei got her test results in the mail. She ripped open the envelope with shaking hands...and then broke into the biggest smile I've ever seen! She passed! She freaking passed the PhD English Examination!Mei scooped me up and swung me around in a huge hug. "I did it, Lily! Your big sister is going to be a PhD! All that hard work and effort paid off!"I was so proud of her. Getting through a crazy tough exam like that proved that Mei is one of the smartest, most dedicated people in the whole world. I just hoped that one day, if I ever decide to get a PhD myself, I'll be able to push through super difficult tests like that too.Although let's be honest...four hours of non-stop English? No thank you! I'll stick to the simple one-hour math tests where I am. But good job, Mei! You're amazing!篇6My Big Bro's Hard English TestHi! My name is Xiao Ming and I'm 8 years old. I'm in 3rd grade at Changsha No. 1 Elementary School. My big brother Da Wei is really smart - he's 24 and just finished his master's degree in English at Central South University. Now he wants to get his PhD there too!A few weeks ago, Big Bro had to take a huge English test to try to get into the PhD program. It was the craziest, hardest test I've ever seen! I watched him study for weeks. Let me tell you all about it.First, there was this reeeeeally long reading section. Big Bro had to read like 5 super duper long papers and articles - they looked soooo boring! They were about all sorts of complicated topics like linguistics, literature, philosophy, and history. After reading each one, he had to answer bunches of questions testing if he understood all the confusing details and main ideas. The questions were really hard too, asking him to analyze andcritique the authors' arguments and writing styles. I tried reading one of the passages but I could barely understand a word!Then there was this crazy listening section where Big Bro put on headphones and had to listen to some English lectures, conversations, and presentations. The audio clips were on all these mind-numbing topics again - society, environment, politics, blah blah blah. I fell asleep just listening for 5 minutes! But Big Bro had to keep taking notes while listening and then answer questions testing his comprehension, like picking out the speaker's opinions or the context of certain phrases and stuff. Sounded like torture to me!But that's not all - the test also had a writing section where Big Bro had to write two mega essays in English, one analyzing a piece of literature and one persuasive essay on some philosophical idea. He had to come up with his own arguments and interpretations, organize them clearly, and explain everything in perfect academic English using fancy vocabulary. When I write essays I can barely string a few sentences together, but Big Bro's essays had to be like 800 words each! And the graders would nitpick every little grammar and spelling mistake. No pressure or anything...Lastly, there was this oral section where Big Bro had to have an entire conversation and debate in English with some professors. They threw all these wacky prompts and hypothetical situations at him about random topics like history, culture, politics, you name it. And he had to respond smoothly and analytically, explaining his viewpoints using logic and evidence and junk. Just imagining all those intimidating professors firing questions at me made me want to crawl under my desk!Phew, I'm exhausted just describing this brutally hard test! Big Bro devoted every waking hour for over a month to prepping and practicing for each section. He was constantly reading, writing essays, doing listening drills, reciting speeches out loud, madly highlighting vocab lists, and chugging cups of coffee. By the end he looked like an exhausted zombie.But you know what? After weeks of basically torturing himself, Big Bro rocked that killer exam! His scores in every section were off-the-charts amazing. The professors were crazy impressed with his English skills - he got to demonstrate his total mastery of reading, writing, listening, and speaking at the highest academic level. Now he's been accepted into Central South University's incredibly competitive PhD program to continue his studies! Isn't that awesome?!All I know is, thank goodness I'm still in elementary school with years before I have to take any horrifyingly difficult tests like that. I'll just leave the suffering to my poor big brother while I play video games and dream of summer vacation. But I'm still super proud of Big Bro for being such a genius and working so unbelievably hard. I just hope they go a little easier on him in his PhD classes!。

For each question there are four possibleanswers marked A, B, C and D. Choose the best one and markthe letter of your choice on the ANSWER SHEET.Passage OneThe popular idea that classical music can improve your maths isfalling form favor. New experiments have failed to support the widely publicized finding that Mozart 's music promotes mathematical thinking.Researchers reported six years age that listening to Mozart brings about short-tem improvements in spatial-temporal reasoning, the type of thinking used in maths. Gordon Shaw of the University of California at Irvine and Frances Rauscher of the University of Wisconsin in Oshkosh had asked students to perform spatial tasks such as imagining how a piece of paper would look if it were folded and cut in a certain pattern.Some of the students then listened to a Mozart sonata and took the test again. The performance of the Mozart group improved, Shaw found. He reasoned that listening to Mozart increases the number of connections between neurons.But Kenneth Steele of Appalachian State University in North Carolina learnt that other studies failed to find this effect. He decided to repeat one of Shaw's experiments to see for himself.Steele divided 125 students into three groups and tested their abilities to work out how to paper would look if cut and folded. One group listened to Mozart, another listened to a piece by Philip Glass and the third did not listen to anything. Then the students took the test again.No group showed any statistically significant improvement in their abilities. Steele concludes that the Mozart effect doesn't exist. “It 's about as unproven and as unsupported as you can g”eth.e says.Shaw, however, defends his study. One reason he gives is that people who perform poorly in the initial test get the greatest boost from Mozart, but Steele didn't separate his students into groups based on ability. “ We' sretill at the stage where it needs to be examined. ”Shaw says. “I suspect that the more we understand the neurobiology, the more w'ell be able to design tests that give a robust effec”t.61. It has been recently found out that ________A. Mozart had an aptitude of music because of his mathematicalthinkingB. classical music cannot be expected to improve on'se mathC. the effects of music on health are widely recognizedD. music favors one's mathematical thinking62. Which of the following pairs, according to the widely publicized finding, is connected?A. Paper cutting and spatial thinkingB. The nature of a task and the type of thinkingC. Classical music and mathematical performanceD. Mathematical thinking and spatial-temporal reasoning63. In Shaw's test, the students would most probably _____A. draw the image of the cut paperB. improve their mathematical thinkingC. have the idea about classical music confirmedD. increase the number of neurons in their brains64. From Steele's experiment we say that ____ .A. his hypothesis did not get proven and supportedB. it was much more complicated than Shaw'sC. the result were statistically significantD. Shaw's results were not repeatable65. Shaw is critical of ________A. Steele's results presented at a wrong stageB. Steele's wrong selection of the testeesC. Steele's ignorance of neurobiologyD. Steele's test designPassage TwoLong-suffering couples take heart. There is a good reason for those endless arguments in the front of the car: men and women use different parts of the brain when they try to find their way around, suggesting that the strategies they use might also be completely different.Matthias Riepe and his colleagues at the University of Ulm in Germany asked 24 healthy volunteers---half of them men, half women---to find theirway out of three virtual-reality mazes displayed on video goggles. Meanwhile, the researchers monitored the volunteers' brain activity using a functional magnetic resonance imaging (fMRI) scanner. This showed that men and women called on strikingly different brain areas to complete the task. “I didn't expect it to be so dramatic,” says Riepe.Previous students have been shown that woman rely manly on landmarks to find their way. Men use these cues too, but they also use geometric cues, such as the angle and shape of a wall or a corner. Such studies also suggest that men navigate their way out of unfamiliar spaces more quickly, as Riepe found in his study, too.Riepe discovered that both men and women used parts of the parietal cortex towards the top of the brain, the right side of the hippocampus and a few other well-established areas to find their way out. Neuroscientists think that the parietal regions help translate what the eyes see into information about where the body is in space, while the hippocampal region helps progress how objects are arranged.But other regions seemed to be exclusively male or female. The men engaged the left side of their hippocampus, which the researcherssay could help with assessinggeometry or remembering whether they have already visited a location. The women, by contrast, recruited their right frontal cortex. Riepe says this may indicate that they were using their “working memory”, trying to keep in mind the landmarks they had passed.“It fits very well with the animal studies, ”says Riepe. He points out that there seem to be similar differences in rats. For example, damage to the frontal lobe will impair a female 's sense of direction, but not a mal'es.66. The studies on the driving issue have evolved _________A. from the car to the driverB. from the reality to the virtual -ealityC. from the physical cues to the parts of the brainD. from the cues of navigation to the strategies of driving67. The different parts of the brain men and women use to find their wayaround, according to the passage, refer to _______A. the left side of the hippocampus and the right frontal cortexB. the right and left side of their hippocampuses respectivelyC. the right and left hemisphere of their brains respectivelyD. the parietal cortex and the hippocampus as a whole68. The part of the brain women use may help explain whythey ___________ .A. use geometric cues to navigateB. have a better memory than menC. rely mainly on landmarks to find their waysD. behave less aggressively than men in driving69. T he reason for the differences in the sexes, according to Riepe, could beA. the environmental factorB. the psychological factorC. the innate factorD. all of the above70. Which one of the following questions did the studies answer?A. How do women and men drive differently?B. How can we detect the brain activities during driving?C. Why do men and women argue over which route to take?D. Why does the damage to the frontal lobe impair the sense ofdirection?Passage ThreeWork has left you frazzled. Your legs ache when you get back fromthe gym …don 'pop those aspiri ns just yet. Think hot spri ngs. Cranking up a hot tub and hopping in is a actural remedy that can provide significant relief from physical pain and stress.There are more than three million home spas in the U.S. today. Thereare numerous reasons spas have made the move from the decks of Hollywood producers to the back yards of middle America. Spas help reduce the effect of stress on your body, assist in muscle recovery after the stress of exercise, and help heal muscles near arthritic joints.There ate three elements to hydrotherapy that, in tandem, provide these healing effects on the body: heat, buoyancy, and motion. When you exercise, your muscles develop thousands of microscopic tears which result in painful lactic acid build-up in the muscle tissue. Hydrotherapy's motion and warmth cause blood vessels to dilate, lowering blood pressure and speeding the flow of oxygen, endorphins, and cell-repairing nutrients to injured muscles. Additionally, buoyancy of the water reduces the strain on your knees and joints which allow the surrounding muscles to relax. This can be of crucial help to arthritis sufferers, because when joints are inflamed, the surrounding muscles become tense to protect them. Relaxing in a spa then makes your muscles more limber and reduces the pain. Water's healing potential has long been known.We don't tend to associate intelligence with our bodies, yet as Thomas Edison said, “ Greatideas originate in the muscles.”Radical psychoanalyst Wilhelm Reich believed that many of us inhibit or deny impulses, feelings, traumas, and stressesby tightening our muscles and creating a kind of “body armor.”He felt that as you cut off the source of pain, you also cut off the source of pleasure. By loosening body armor, byletting muscles relax, you can return to a feeling of flow and creativity.Few things can relax the body more than a home spa. And a relaxed body leads to a relaxed mind. There is no better place to start relaxing than an hour in your home hot springs.71. To begin with, what does the author insist we avoid doing?A. Undergoing physical pain and stress.B. Taking aspirin tablets.C. Going to the gym.D. Relaxing in a spa.72. What does the second sentence in the second paragraph implies?A. The origin of spas.B. The popularity of hot springs.C. The flux of people to mid America.D. The spas as a luxury only for the rich.73. After the stress of exercise, the injured muscles ___A. will lead to arthritisB. contain plenty of microscopic tearsC. can cause blood pressure to declineD. will boost the production of cell-repairing nutrients74. The author contends that our creativity _____A. can be enforced by the‘body armor”B. does not occur in mind but in the musclesC. can be hampered with our muscles tightenedD. is good only when we are free of mental an d physical stress75. Which of the following can be the best title for the passage?A. Spas, the Best RelaxationB. A Brief History of Spas.C. Spa Resorts in the USAD. Soak AwayStressPassage FourConvincing the public to follow health advice can be tough and time-consuming. This may be why changes to health messages are often fiercely resisted by those whose job is to get the advice across. So, for example, the suggestion that smokers who cannot quit should reduce their exposure to harm by switching to chewing tobacco met with extreme opposition.A still more ferocious debate is emerging over the health impact of sunshine. For the past 20years, advice on sunlight has come from dermatologists who rightly warn people to cover up when they ventureoutside for fear of developing skin cancer. But evidence from researchersin other fields now suggests that short periods in the sun without protection—sometimes as little as a few minutes a day---can preventmost other major forms of cancer.This surprising conclusion stems from findings that vitamin D. which is made by skin cells exposed to the sun's ultraviolet rays, is a potent anti-cancer agent. The researchers who made this discovery are eager to be heard. But their message is about as welcome as a bad rash, particularly in countries such as Australia and the US where fair-skinned immigrants living at Mediterranean latitudes have made skin cancer a huge problem.The American Academy of Dermatology argues that advocating one carcinogen ---- U V radiation --- to protect against other forms of cancer is dangerous and misleading. If people need more vitamin D, they should take a multivitamin or drink milk fortified with it, says the academy. Unfortunately, the solution is not as simple as that. Critics also argue that the protective effect of sunlight is not yet proved. While this may be true, the evidence is very suggestive. The case is built on several studies that bring together cellular biology, biochemistry and epidemiology.And all the criticism of this theory counts for nothing if, as some of its advocates, suggest, the number of people dying for lack of sunlight is four times as high as those dying from skin cancer. At the same time, those advocates must not overstate their case. Everyone wants to save as manylives as they can.What we need now is for national medical research bodies and cancer research organizations to investigate the relative risks and benefits of sunshine. This will almost certainly mean more epidemiological work, which should start as soon as possible. As for the public: give them the facts, including risk estimates for short periods in the sun---and for covering up. It is patronizing(施恩于人的) to assume that people cannot deal with complex messages.What we definitely do not want is a war of words between groups with polarized views, and no prospect of the issue being resolved. That way will only lead to confusion, distrust of doctors and more unnecessary deaths.76. According to the first two paragraphs, the problem seems to be that the public ________A. cannot be reached by health messagesB. is torn between two health messagesC. never trust those health researchersD. are divided over health problems77. The recent opposition goes to ________A. the protective value of sunshineB. the cancer-causing effect of sunshineC. the debate over the health impact of sunshineD. the two controversial messages about skin cancer78. According to the critics, the health impact of sunshine ________A. will be epidemiologically provedB. is misleading the public altogetherC. merits a comprehensive investigationD. can be easily addressed with a simple solution79. The author implies that health messages should be made easy _____A. to debateB. to swallowC. to estimateD. to publicize80. As for the issue, the author suggests that the public ________A. decide on their own how much sunshine is too muchB. avoid unnecessary deaths due to complex messagesC. be provided with reliable and practicable messagesD. facilitate the understanding of health messagesPassage FiveI make my way down the three chilly blocks to an old diner on Commercial Street. I am meeting a new friend for lunch. I 've never been here before: this is not my part of town. And so I arrive early, to sit in an old wooden booth and learn what I can about the place.They call it Katie 's kitchen. One hundred years ago, it was a bar. The barstools remain, but through community donations, it 's now a respectablerestaurant. The hostess, casher, and waiters are residents of a nearby hotel for the transient and unemployed and work here to gain dignity and job skills. Both the hotel and restaurant are run by Sister L, a nun with a heart and a great deal of business sense.My new friend arrives. He works down the street, in a clinic for indigent (穷的)persons; he knows these people. The workers and many of the clients seem to know him too, for I see warmth and proud smiles on their faces as he greets them. Behind him, a few nameless souls wander in from the street in a swirl of December wind.I focus on our waitress. A pretty girl of perhaps 18 years, she is all smiles and grace. I wonder for a moment why she's here ---what her story is;what her dreams are; whether she is raising children on her own. But I cannot hold the thought, for she reminds me of another waitress at my favorite coffee shop---a college student with a bright future.Some time later, I finish my soup and sandwich---a good meal made better because of the smile of the girl who served it. I wipe my mouth and go to pay. Eight dollars and sixty-four cents, for two. To our embarrassment, my friend and I discover that neither of us has cash, and my credit card is not good here.We sheepishly approach Sister L, who smiles and takes my bill. “It o'ka s y.”she says. “We'll buy your lunch. It 'll be our pleasure.”Slowly, I leave the world of the diner. Back at the hospital where I work, my boss laments our financial woes. “ We' rreeally tight,”he says.”。

Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the best answer and mark the corresponding letter on ANSWER SHEET Ⅰ with a single line through the center.Passage OneNowadays, with plentiful ice and electric churning, few people recall the shared excitement of the era when making ice cream was a rarely scheduled event. Then the iceman brought to the back door, on special order, a handsome 2-foot-square cube of cold crystal and everyone in the family took a turn at the crank. The critical question among us children was, of course, who might lick the dasher. A century or so ago the novelist Stendhal knew only hand-churned ice cream and, when he first tasted it, exclaimed, “What a pity this isn't a sin!”Hand-churning is still tops for perfectionists for no power-driven machine has yet been invented that can achieve a comparable texture. Even French Pot, the very best commercial method for making ice cream, calls for finishing by hand.Ice creams are based on carefully cooked well-chilled syrups and heavy custards, added to unwhipped cream. No form of vanilla flavoring can surpass that of vanilla sugar or of the bean itself, steeped in a hot syrup. If sweetened frozen fruits are incorporated into the cream mixture instead of flesh fruits, be sure to adjust sugar content accordingly.Make up mixtures for chum-frozen ice creams the day before you freeze, to increase fill the container only 3/4 full to permit expansion. To pack the freezer, allow 3 to 6 quarts of chipped or cracked ice to 1 cup of coarse rock salt. Pack about 1/3 of the freezer with ice and add layers of salt and ice around the container until the freezer is full. Allow the pack to stand about 3 minutes before you start turning. Turn slowly at first, about 40 revolutions a minute, until a slight pull is felt. Then triple speed for 5 to 6 minutes. If any additions, such as finely cut candied or flesh fruits or nuts are to be made, do so at this point. Then repack and taper off the churning to about 80 revolutions a minute for a few minutes more. The cream should be ready in 10 to 20 minutes, depending on the quality.If the ice cream or ice is to be used at once, it should be frozen harder than if you plan to serve it later. Should the interval be 2 hours or more, packing will firm it. To pack, pour off the salt water in the freezer and wipe off the lid. Remove the dasher carefully, making sure that no salt or water gets into the cream container. Scrape the cream down from the sides of the container. Place a cork in the lid and replace the lid. Repack the container in the freezer with additional ice and salt, using the same proportions as before. Cover the freezer with newspapers, a piece of carpet or other heavy material.The cream should be smooth when served. If it proves granular, you used too much salt in the packing mixture, overfilled the inner container with the ice cream mixture or turned too rapidly. If you are making a large quantity with the idea of storing some in the deep-freeze, package in sizes you plan on serving. Should ice cream be allowed to melt even slightly and is then refrozen, it loses in volume and even more in good texture.31.In the first paragraph, “took a turn at the crank” could be paraphrased ______.A.“helped to mix the ice cream”B.“ate some ice cream”C.“helped break up the ice with a hammer”D.“protected the ice cream from children”32.According to the writer truly perfect ice cream ______.A.is now common and inexpensive at most storesB.is only possible with hand laborC.should be melted and then refrozenD.needs to be a sin33.When ice cream is being hand-churned it is surrounded by a mixture of ______.A.syrup and cream B.syrup and iceC.salt and ice D.flesh fruit and ice34.In paragraph 4, “taper off” means ______.A.cut up B.stop C.speed up D.slow down35.This passage reflects an era when ______.A.people liked a little salt in their ice creamB.making ice cream was an occasional form of family entertainmentC.ice cream was not popularD.people did not knew now to make cheese with their creamPassage TwoFood and drink play a major role in Christmas celebrations in most countries, but in few more so than in Mexico. Many families over the festive season will do little more than cook and ingest a seemingly constant cycle of tortillas, fried beans, meat both roasted and stewed, and sticky desserts for days on end.Thus does the extended family keep on extending—further and further over their collective waistlines.Lucky them, you might think. Except that Mexico's bad eating habits are leading to a health crisis that most Mexicans seem blissfully unaware of. Obesity and its related disorder, diabetes, are now major health concerns in a country where large rural regions are still concerned more with under- than with over-nourishment. In its perennial rivalry with the United States, Mexico has at last found an area in which it can match its northern neighbor—mouthful for mouthful.The statistics are impressive, and alarming. According to the OECD, Mexico is now thesecond fattest nation in that group of 30 countries A health poll in 1999 found that 35% of women were overweight, and another 24% technically obese. Juan Rivera,an official at the National Institute of Public Health, says that the combined figure for men would be about 55%, and that a similar poll to be carried out next year will show the fat quotient rising. Only the United States, with combined figures of over 60%, is a head.That situation also varies geographically. Although Mexicans populate the north of their country more sparsely than the south, they make up for it weight-wise. A study published by the Pan-American Health Organization a month ago showed that in the mostly Hispanic population that lives on either side of the American-Mexican border, fully 74%of men and 70%of women are either over weight or obese.Moreover, even experts have been surprised by how rapidly the nation has swollen. Whereas the 1999 poll showed 59%of women overweight or obese, only 11 years previously that figure was just 33 %. Nowhere is the transformation more noticeable than in the prevalence of diabetes, closely linked to over-eating and obesity. In 1968, says Joel Rodriguez of the Mexican Diabetes Federation, the disease was in 35th place as a direct cause of mortality in Mexico, but now it occupies first place, above both cancer and heart disease. With about 6.5m diabetics out of a population of 100m, Mexico now has a higher rate than any other large country in the world. Not surprisingly, Mr. Rodriguez argues that Mexi co is in the grip of an “epidemic”.Nor does it tax the brain much to work out that the causes of these explosions in obesity and diabetes are the Mexican diet and a lack of exercise. For most Mexicans, food consumption, not just at Christmas but all year round, is an unvarying combination of refried beans, tortillas, meat and refrescos, or fizzy drinks; they consume 101 liters of cola drinks per person per year, just a little less than Americans and three times as much as Brazilians.Meanwhile, the lack of exercise, Mr. Rivera argues, is a symptom of rapid urbanization over the past 30 years. Obesity and diabetes rates remain slightly lower in rural areas, indicating that manual labor endures as an effective way to stave off weight gain. In Mexico City, though, pollution and crime have progressively driven people out of the parks and the streets, so most now walk as little as possible—preferably no further than from the valet-parking service to the restaurant. To combat the fat, health professionals say that the country must first realize that it is indeed in the grip of an epidemic.Other diseases, such as AIDS and cancer, have captured mostof the publicity in recent years; obesity and diabetes have been comparatively neglected.But these are also, as in other developing countries, mainly problems of the urban poor. It is a symptom of their growing prosperity that these parts of the population have, probably for the first time, almost unlimited access to the greatest amount of calories for the smallest amount of money. But with little knowledge of nutritional values, their diets are now unbalanced and unhealthy.Low-carb products and other dietary imports from the United States have already made an appearance on the posher Mexican supermarket shelves. They may go into be shopping baskets of the rake-thin and utterly unrepresentative models who dominate the country's advertising hoardings. But they are still comparatively expensive. For the heaving mass of the population, things may have to get worse before the government, doctors and consumers realize that things have got to start getting better.36.The phrase “on end” in the first paragraph can be replaced by ______.A.until all been consumed B.uprightC.continuously D.until the last day37.Which of the following sentences is TRUE according to the passage?A.Mexicans are eating a lot because of the country's affluence.B.Mexicans can match Americans in the nourishment of their diet.C.Mexicans only overeat during festive seasons.D.Mexico is now the second fattest nation in this world.38.Judging by the context, the word “perennial” in the second paragraph most probably means ______.A.perpetual B.recurring C.transient D.perilous39.Which is the most significant cause of mortality in Mexico?A.Cancer. B.Heart disease. C.Diabetes. D.Epidemic.40.It is known from the passage that from 1988 to 1999 the figure of women overweight or obese in Mexico rose by ______.A.30% B.26% C.35% D.55%Passage ThreeWhen you are small, all ambitions fall into one grand category:when I'm grown up. When I'm grown up, you say, I'll go up in space. I'm going to be an author. I'll kill them all and thenthey'll be sorry. I'll be married in a cathedral with sixteen bridesmaids in pink lace. I'll have a puppy of my own and no one will be able to take him away.None of it ever happens, of course—or dam little, but the fantasies give you the idea that there is something to grow up for. Indeed one of the saddest things about gilded adolescence is the feeling that from eighteen on, it's all downhill; I read with horror of an American hippie wedding where someone said to the groom (age twenty), “You seem so kind a grown up somehow”, and the lad had to go around seeking reassurance that he wasn't, no, really he wasn't. A determination to be better adults than the present incumbents is fine, but to refuse to grow up at all is just plain unrealism.Right, so then you get some of what you want, or something like it, or something that will do all right; and for years you are too busy to do more than live in the present and put one foot in front of the other; your goals stretching little beyond the day when the boss has a stroke or the moment when the children can bring you tea in bed—and the later moment when they actually bring you hot tea, not mostly slopped in the saucer. However, I have now discovered an even sweeter category of ambition. When my children are grown up …When my children are grown up I'll learn to fly an aer o plane. I will career round the sky, knowing that if I do “go pop” there will be no little ones to suffer shock and maladjustment; that even if the worst does come to the worst I will at least dodge the geriatric ward and all that looking for your glasses in order to see where you've left your teeth. When my children are grown up I'll have fragile, lovely things on low tables; I'll have a white carpet; I'll go to the pictures in the afternoon. When the children are grown up I'll actually be able to do a day's work in day, instead of spread over three, and go away for a weekend without planning as if for a trip to the Moon. When I'm grown up—I mean when they're grown up—I'll be free.Of course, I know it's got to get worse before it gets better. Twelve-year-olds, I'm told, don't go to tend at seven, so you don't even get your evenings; once they're past ten you have to start worrying about their friends instead of simply shooting the intruders off the doorstep, and to settle down to a steady ten years of criticism of everything you've ever thought or done or worn. Boys, it seems, may be less of a trial then girls, since they can't get pregnant and they don't borrow your clothes—if they do borrow your clothes, of course, you've got even more to worry about.The young don't respect their parents any more, that's what. Goodness, how sad,still, likeeating snails, it might be all right once you've got over the idea: it might let us off having to bother quite so much with them when the time comes. But one is simply not going to be able to drone away one’s days, toothless by the fire, brooding on the past.41.What interests the writer about young children is that they ______.A.have so many unselfish ambitions B.have such long-term ambitionsC.don't all want to be spacemen D.all long for adult pleasures42.The writer maintains that fantasies ______.A.satisfy ambition B.lessen ambitionC.stimulate ambition D.frustrate ambition43.What does the writer feel is wrong with the modern generation?A.Their wanting to grow up. B.Their not wanting to grow up.C.Their wanting to improve adults. D.Their not wanting to improve adults.44.The writer feels that as an adult one must ______.A.achieve one's ambitions at all costsB.continue to be ambitiousC.find a compromise between ambition and realityD.give up all one's earlier ambitions45.When the children leave home, the writer thinks that ______.A.there will be compensations B.she will be delightedC.she will be desolated D.there will be nothing to doPassage FourFor years, pediatricians didn't worry much about treating hypertension in their patients. After all, kids grow so fast, it's hard keeping up with their shoe size, let alone their blood pressure. Sure, hypertension in adults places them at greater risk of heart attack and stroke. But nobody likes the idea of starting youngsters on blood-pressure medicine they could wind up taking the rest of their lives. Who knows what previously unheard of side effects could crop up after five or six decades of daily use? The rationale has been: kids grow out of so many things, maybe they'll grow out of this too.Now, though, comes word that high blood pressure can be destructive even in childhood. According to a recent report in the journal Circulation, 19 of 130 children with high bloodpressure developed a dangerous thickening of the heart muscle that, in adults at least, has been linked to heart failure. “No one knows if this pattern holds true for younger patients as well,” says Dr. Stephen Daniels, a pediatric cardiologist who led the study at Children's Hospital Medical Center in Cincinnati, Ohio. “But it's worrisome.”Who's most at risk? Boys more than girls, especially boys who are overweight. Their heart works so hard to force blood through extra layers of fat that its walls grow more dense. Then, after decades of straining, it grows too big to pump blood very well. Fortunately, the abnormal thickening can be spotted by ultrasound. And in most case, getting that blood pressure under control—through weight loss and exercise or, as a last resort, drug treatment—allows the overworked muscle to shrink to normal size.How can you tell if yours are like the 670,000 American children ages 10 to 18 with high blood pressure? It's not the sort of thing you can catch by putting your child's arm in a cuff at the free monitoring station in your local grocery. You should have a test done by a doctor, who will consult special tables that indicate the normal range of blood pressure for a particular child's age, height and sex. If the doctor finds an abnormal result he will repeat the test over a period of months to make sure the reading isn't a fake. He'll also check, whether other conditions, like kidney disease, could he the source of the trouble. Because hypertension can be hard to detect, the National Heart, Lung and Blood Institute recommends annual blood pressure checks for every child over age 3.About half the cases of hypertension stem directly from kids being overweight. And the problem is likely to grow. Over the past 30 years the proportion of children in the US who are overweight has doubled, from 5 % to 11%, or 4.7 million kids.You can keep your children from joining their ranks by clearing the junk food from your pantry and hooking your kids—the earlier the better—on healthy, attractive snacks like fruits (try freezing some grapes) or carrot sticks with salsa. Not only will they lower your children's blood pressure;these foods will also boost their immune system and unclog their plumbing. Meanwhile, make sure your kids spend more time on the playground than with their Play Station. Even if they don't shed a pound, vigorous exercise will help keep their blood vessels nice and wide, lowering their blood pressure. And of course, they'll be more likely to eat right and exercise if you set a good example.46.This piece of writing is mainly addressed to ______.A.parents B.boys C.gifts D.pediatrician47.The word “unclog” in paragraph 6 can be replaced by ______.A.fix B.clear C.hinder D.dismantle48.By saying “It's not the sort of thing you can catch by putting your child's arm in a cuff at the free monitoring station in your local grocery”, the writer implies ______.A.hypertension is hard to detectB.children often refuse to have their blood pressure testedC.you'll have to pay a lot of money if you want to have your child's blood pressure checked in a groceryD.in a local grocery, you are free to determine how to have your child's blood pressure examined49.Which of the following is not suggested by the writer to control hypertension?A.Drug treatments. B.Weight loss.C.Exercise. D.Overwork.50.We can conclude from the passage that ______.A.children with hypertension are unlikely to suffer from heart attack and strokeB.parent's blood pressure decides their children's blood pressureC.besides overweight, there are other factors resulting in hypertensionD.vigorous exercise sometimes will lead to heart troublePart ⅢCloze (10 points)Directions:Fill in each of the following blanks with ONE word to complete the meaning of the passage. Write your answer on ANSWER SHEET Ⅱ.Even geologist is familiar with the erosion cycle. No sooner has an area of land been raised above sea-level than it becomes subject to the erosive forces of nature. The rain beats down on the ground and washed 51 the finer particles, sweeping them into rivulets and into rivers and out to sea. The frost freezes the rain water in cracks of the rocks and breaks 52 even the hardest of the constituents of the earth's crust. Blocks of rock dislodged at high levels are brought down by the force of gravity. Alternate heating and 53 of bare rock surfaces causes their disintegration. In the dry regions of the world the wind is a powerful force in removing materialfrom one area to another. All this is natural. But nature has also provided certain defensive forces. Bare rock surfaces are in 54 course protected by soil, itself dependent initially on the weathering of the rocks. Slowly 55 surely, different types of soil with differing “profiles” evolve the main types depending primarily on the climate. The protective soil covering, once it is formed, is hold together by the growth of vegetation. Grass and herbaceous plants, 56 long, branching tenuous roots, hold firmly together the surface particles. The 57 is true with the forest cover. The heaviest tropical downpours beating on the leaves of the giant trees reach the ground only 58 spray, gently watering the surface layers and penetrating along the long passages provided by the roots to the lower levels of the soil. The soil, thus protected by grass, herb, or trees, furnishes a quiet habitat for a myriad varied organisms—earthworms that importantly modify the soil, bacteria, active in their work of converting 59 leaves and decaying vegetation into humus and food for the growing plants. Chemical action is constantly taking 60 ; soil acids attack mineral particles and salts in solution move from one layer in the soil to another.Part ⅣTranslation (20 points)Section A (10 points)Directions:Put the following passage into Chinese.Dun took a deep breath, thinking over what had been said and searching in his mind for a possible course of action. Not for the first time in his flying career, he felt himself in the grip of a cute sense of apprehension, only this time his awareness of his responsibility for the safety of a huge, complex aircraft and nearly sixty lives was tinged with a sudden icy premonition of disaster. Was this, then what it felt like? Older pilots, those who had been in combat in the war, always maintained that if you kept at the game long enough you'd buy it in the end. How was it that in the space of half an hour a normal, everyday, routing flight, carrying a crowd of happy football fans, could change into a nightmare nearly four miles above the earth, something that would shriek across the front pages of a hundred newspapers?Section B(10 points)Directions:Put the following passage into English.在美国历史上人们最津津乐道的政治问题恐怕就是法律与秩序。

They work by introducing a small amount of weakened or dead virus or bacteria into the body, allowing the immune system to recognize and fight off the pathogen more effectively in the future. Vaccinations have been instrumental in eradicating deadly diseases such as smallpox and polio. However, there are some potential risks associated with vaccinations, such as allergic reactions or rare side effects.

2013年全国医学博士英语统一考试真题全文共6篇示例,供读者参考篇1The Big Grown-Up TestHi there! My name is Lily and I'm 8 years old. I'm going to tell you all about this really big test that happened a few years ago. It was called the 2013 National Unified English Exam for Medical Doctoral Students. That's a really long name, isn't it? I'll just call it the Big Grown-Up Test.I didn't actually take the test myself because I'm just a kid. But my mom is a doctor and she had to take a test kind of like it when she was in medical school a long time ago. She said it was super hard and made her really nervous! The Big Grown-Up Test was only for the really smart adults who wanted to get their "doctoral" degree, which is like the highest level of education you can get.From what I understand, the test happened all across China on the same day. Thousands of grown-ups had to go to test centers and take it. Can you imagine having to sit still and take ahuge test for hours and hours? I don't think I could do that. I'd get way too antsy!The test had four main sections - listening, reading, writing, and speaking. For the listening part, the grown-ups had to listen to recordings and answer questions about what they heard. In the reading section, they had to read really long, complicated passages and answer questions proving they understood everything.But here's the crazy part - the whole test was in English! And not just simple English either. We're talking medical English with all those big fancy words that I can't even pronounce. My mom showed me a practice test once and I couldn't understand a word of it. Just a bunch of mumbo-jumbo if you ask me!For the writing section, the grown-ups had to write an essay or paper about some scientific topic. They couldn't just write "The cat ran after the bird" type stuff. They had to use their best English and fanciest words to discuss complex ideas. No "See Spot run" for these over-achievers!Then for the speaking portion, they had to actually talk out loud and have conversations in English about different medical scenarios. They were graded on their vocabulary, pronunciation, and how well they could explain things. If they slipped up andaccidentally spoke Chinese, it was an automatic fail! That's so much pressure.From what my mom told me, everyone taking the Big Grown-Up Test had studied English for years and years. They took special classes and worked really hard to prepare. But even then, the test was still incredibly difficult. I guess that's why they call it the "doctoral" level. Only the best of the best could pass!My mom said the listening section was the hardest part for her because you only get to hear things once. If you zone out for even a second, you're totally lost. And with all those crazy medical terms being fired at you rapid-fire, it was really easy to miss important details. She had to practice listening exercises every single day to get ready.The reading section was also a killer because the passages were just sooooooo long and dry. My mom showed me one that was 20 pages about the molecular biology of cancer. BO-RING! She said you had to be able to skim for key information really quickly but also understand every little detail. It took crazy focus.For the writing section, my mom's biggest challenge was making sure she used proper academic style. You couldn't just write normally like a letter to your friend. It had to be formal"scholarly" English with a clear and logical structure. No slang or contractions allowed!And then speaking English out loud without stumbling over vocabulary? My mom said that part made her want to cry. You had to be able to think and speak at the same time without any awkward pauses. One little "umm" and you could blow the whole thing. She practiced having fake doctor-patient conversations with her English tutor every week. Talk about nerve-wracking!Even though my mom studied so hard, she was still a nervous wreck before the Big Grown-Up Test. She stayed up late every night for weeks going over practice questions. The day of the test, she barely slept at all. I remember her pacing around the apartment that morning, muttering English words under her breath like "hematology...nephrology...gastroenterology." I thought she was going crazy!When she finally came home after the marathon test session, she looked like a zombie. She plopped down on the couch, completely drained from using her brain so much. All she could do was stare at the wall. But you know what? A few months later, she found out she passed! We had a huge family celebration. All that hard work had paid off.After hearing how brutal the Big Grown-Up Test was, I have even more respect for doctors like my mom. Can you imagine having to prove your medical knowledge IN ENGLISH at that level? With listening, reading, writing, speaking...the whole shebang? It's amazing that anyone can do it! I guess that's why kids can't just become doctors. You have to be one smart and determined grown-up.Well, that's the story of the 2013 National Unified English Exam for Medical Doctoral Students in China. It was basically a mental marathon testing the English skills of the cream of the crop. I don't know about you, but I'm staying far away from any exams that extreme! Give me some simple addition and subtraction any day. I'll leave those crazy Big Grown-Up Tests to the adults. Let me know if you ever want to hear about the "iguanas of the Galapagos" or something equally riveting like that killer medical exam. I'll keep my stories kid-friendly!篇2The 2013 Doctor TestHey guys! Today I'm going to tell you all about this really hard test that medical students have to take. It's called the 2013National Unified English Test for Medical Doctoral Students. That's a huge name for a test!My older sister Sarah is studying to be a doctor. She had to take this big important test last year. I watched her study for it and it looked super duper hard. There was a ton of big medical words I couldn't even pronounce!Sarah said the test had four different sections. The first part was listening. They played audio recordings and asked questions to see if you understood what you heard. My sister practices this by watching English TV shows and movies without subtitles. She said practicing listening is really important for talking to patients someday.The next section was reading. You had to read a bunch of different passages and articles and answer comprehension questions. Sarah read giant medical textbooks to get ready. The readings were probably really boring unless you're realllly into that doctor stuff.After that was the writing section. You had to write essays and reports based on pictures or prompts they gave you. Sarah practiced writing samples all the time. I helped her check for mistakes sometimes but a lot of it was way over my head!The final part was speaking. You had to record yourself answering questions and explaining things out loud. It tests if you can communicate well in English. Sarah set up a video camera and recorded herself talking for hours to get ready. I'm glad I didn't have to listen to all that practice!Overall it sounded like the toughest test ever. Sarah studied non-stop for months beforehand. She said it was crucial to do well since getting a high score can help you get into better medical programs and jobs after graduating.The test was administered on paper at testing centers across the country. Maybe thousands of students took it at the same time? I can't even imagine having to take a test that massive and important. No thank you!When Sarah finally took the real test, she was sooo nervous. But she felt prepared after all her hard work studying. She had to travel to the closest testing site which was a few hours away from our house. Can you believe she had to take the whole 4-hour test in just one sitting? No breaks! I don't know how she stayed focused that long.I'm telling you, this 2013 Unified English Test was no joke. Just listening to Sarah talk about it gave me anxiety! The test covered every little detail of medical communication in English. Itreally separated the students who were proficient in English from those who weren't quite there yet.After what felt like an eternity, Sarah got her score report in the mail. She passed with flying colors! We were all so proud and relieved for her. First she celebrated by going out for a huge ice cream sundae. She deserved It after that monster of a test!Apparently Sarah's high score will allow her to apply to lots of competitive medical residency programs after she finishes regular doctor school. That's really good news since those programs are super exclusive and tough to get into. All thanks to nailing the 2013 National English Test!Phew, I'm exhausted just from talking about this test! I'm definitely not cut out to be a doctor. I'll stick to cartoons and video games for now. But I'm really proud of my amazing big sis Sarah for powering through that incredibly difficult English exam. After hearing how intense it was, I have a whole new respect for doctors and medical students.Well, that's my extremely detailed and passionate summary of the 2013 National Unified English Test for you all! I hope I did a good job explaining it from a kid's point of view. Let me know if you have any other questions! Time for a snack break...篇3The Big Scary Test DayWow, today was a really big day! I had to wake up super early because my mom and dad said I had to take a really important test. They called it the "2013 National English Test for Medical Doctoral Students." That's a really long name for a test! I don't even know what a "doctoral student" is.When we got to the testing place, there were so many grown-ups there. I felt like a tiny little kid in a sea of giants! The room was huge, and there were desks set up everywhere. My mom pointed to a desk near the front and told me that was going to be my spot for the test. I was really nervous!The test proctor lady came in and started explaining all the rules. She said we couldn't talk, couldn't look at each other's papers, and had to keep our eyes on our own test booklets. It sounded really strict! I got even more nervous thinking about how I wasn't allowed to ask any questions during the test.Finally, the proctor said it was time to begin. She passed out the test booklets, and they were super thick! My booklet had to be at least 100 pages long. I gulped and thought to myself, "How am I ever going to finish this whole thing?"The first section was listening comprehension. The audio started playing, and a friendly-sounding lady's voice came through the speakers. She was talking about something called "medical ethics." I had no idea what that meant, but I tried my best to listen carefully and answer the questions.Next up was the reading section. The passages were all about science and medical stuff. There were so many big words that I didn't understand! I just tried to read slowly and carefully, and answer the questions to the best of my ability.After what felt like forever, we finally got to take a short break. I stretched my legs and used the bathroom. My brain felt like mush from trying so hard to concentrate.The writing section was probably the hardest part for me. We had to write a whole essay about some complicated medical topic. I did my best to string some sentences together, but I'm not sure if it made any sense. Writing is hard!The very last section was speaking. We had to goone-by-one into a different room and answer some questions out loud while a lady recorded us on a computer. I was so nervous that my hands were shaking! But the lady gave me an encouraging smile, and I tried my best to speak slowly and clearly.At long last, the whole test was finally over! My brain felt like a big jumbled mess, but I was so relieved that it was done. All the grown-ups were packing up their things and getting ready to leave. I found my mom and dad, and they gave me a big hug and told me they were proud of me for working so hard.On the way home in the car, I fell into a deep sleep. Taking that medical doctoral test was the most difficult thing I've ever done in my whole life! I sure hope I did okay on it. But either way, I'm just glad it's over. Phew, what a day!篇4Hi there! My name is Timmy and I'm 8 years old. Mrs. Thompson asked me to write about my experience taking the 2013 National Medical Doctoral English Unified Exam. I know it sounds really hard for a kid like me, but I'll do my best to explain it!It all started a few weeks ago when my big sister Susie came home from medical school. She looked really stressed out. When I asked her what was wrong, she told me she had to take this huge exam called the "National Medical Doctoral English Unified Exam." It's a test that all medical students have to pass before they can become real doctors.Susie said the exam was going to be super duper hard because it's all in English. English is like a foreign language to her since we only speak Chinese at home. She had to learn all sorts of big fancy medical words in English. Just thinking about it made my head hurt!Anyway, Susie had to study day and night to get ready. Our house was covered in medical textbooks, flashcards, and empty coffee mugs. I tried to help her study, but I could barely even read the words, let alone understand what they meant!Finally, the day of the big exam arrived. Susie was so nervous, she barely ate any breakfast. I gave her a high-five for good luck as she headed out the door. "You've got this, sis!" I shouted. She just grimaced and kept walking.The exam was held at a huge testing center downtown. There were hundreds of students there, all looking just as stressed as Susie. The rules were super strict - no talking, no cheating, and definitely no bathroom breaks! I'm glad I wasn't the one taking it.Susie said the first part was listening comprehension. She had to listen to doctors giving instructions and answer questions about what they said. Next up was reading comprehension about different medical cases and procedures. Susie told mesome of the words were so long and confusing, she wanted to cry!After that was the writing section where she had to explain medical concepts in clear English. Susie's hand cramped up from writing so much. Then there were all sorts of other sections testing grammar, vocabulary, speaking ability, you name it!The exam lasted over 6 hours. SIX HOURS! I can't even sit still for that long when I'm watching cartoons. Susie looked exhausted when she finally emerged from the test center. Her face was pale and she could barely speak from using so much brainpower.I gave her a big celebratory hug when she got home. She plopped down on the couch and didn't move for like three hours. Mom made her favorite dumplings for dinner to congratulate her on surviving the epic exam day.A few weeks later, the results came in the mail. Susie passed!! She got high enough scores to start her medical residency. I was super proud of her for proving she was smart enough to be a doctor, even in English.In the end, Susie said the exam was one of the hardest things she'd ever done in her entire life. But she was also really glad shepushed herself and worked so hard to achieve her dream career. Seeing my big sis overcome that huge challenge inspired me to never give up, no matter how difficult things get.Who knows, maybe one day I'll be the one taking the crazy Medical Doctoral English Exam? Although I'll probably need to learn English first before I can think about becoming a doctor. Baby steps!Well, that's my tale of the legendary 2013 medical exam. I hope I explained it okay! Let me know if you need me to dumb it down even more. Writing at an 8-year-old level is harder than it looks. Now if you'll excuse me, I have an important kindergarten final coming up on finger painting...篇5My Trip to the DoctorHi! My name is Lily and I'm 8 years old. Today I'm going to tell you all about my trip to the doctor last week. It was a really exciting adventure!It all started on Monday morning. I woke up and my throat was super sore and scratchy. I could barely swallow without it hurting. "Uh oh," I thought, "I must be getting sick."I went to the kitchen where my mom was making breakfast. "Good morning sweetie," she said in a cheery voice. "Are you ready for another fun day at school?"I shook my head sadly. "No mom, my throat really hurts," I croaked out in a raspy voice. I stuck out my bright red, swollen tonsils for her to see.My mom's eyes got really wide. "Oh no, you poor thing!" she exclaimed. "That looks like a nasty case of tonsillitis. I better call the pediatrician right away to get you an appointment."The pediatrician is just a fancy word for a kids' doctor. My mom dialed their number and talked on the phone for a few minutes. When she hung up, she looked at me with a sympathetic smile."Okay sweetie, I was able to get you in to see Dr. Stevens this afternoon at 3 o'clock. In the meantime, I want you to go rest on the couch and I'll bring you some warm tea with honey to soothe your throat."I nodded listlessly and shuffled over to the living room couch, wrapping myself up in a fuzzy blanket. My mom brought me the tea a little later and I sipped it slowly, relieved by the smoothing sensation on my poor, abused throat.A few hours later, it was time to head to the doctor's office. We loaded into our blue minivan and off we went! I had visited Dr. Stevens many times before, so I knew the way to her office like the back of my hand.When we arrived, my mom checked me in at the front desk. "Lily Anderson to see Dr. Stevens for a 3 o'clock sick visit," she told the friendly receptionist. We only had to wait about 10 minutes before a nurse opened the door to the hallway."Lily Anderson?" she called out in a singsong voice. I perked up, time for the real fun to begin! We followed the nurse down the hallway lined with colorful drawings by kids. She brought us into the examination room and checked my temperature, blood pressure, and other vitals."The doctor will be right in," she told us before leaving the room. My mom and I had to wait just a couple of minutes before there was a knock at the door."Hello there!" the cheery voice of Dr. Stevens called out as she entered. "What seems to be the trouble today?""Lily has a really bad sore throat, I'm afraid she may have tonsillitis," my mom explained while I just nodded weakly.Dr. Stevens had me open my mouth wide and say "Ahhhh" while she inspected my crimson tonsils with a tongue depressor. She also felt around my neck checking for swollen lymph nodes."You're absolutely right, those tonsils are very inflamed and swollen," Dr. Stevens declared with a frown. "And I can feel her lymph nodes up as well. This is definitely a case of acute tonsillitis, most likely caused by a bacterial infection."My heart sank - bacterial infection sounded really serious and scary! I started to whimper but my mom gave my hand a reassuring squeeze."Not to worry Lily," Dr. Stevens said with a kind smile, "we'll have you feeling good as new in no time. I'm going to prescribe a course of antibiotics to get rid of that nasty tonsillitis."The antibiotics would be special medicine that I'd have to take for about 10 days to kill the bacterial infection making me sick. Dr. Stevens called the prescription into my regular pharmacy and told my mom I should start feeling better in a day or two once the antibiotics kicked in.As we left the office, I felt a huge wave of relief wash over me. Taking some occasional gross-tasting medicine was no big deal if it meant I would stop feeling so miserable! Sure enough, after acouple days of the antibiotics, the swelling in my throat had gone down dramatically and I was on the road to recovery.I was so thankful my mom took me to see Dr. Stevens right away. Tonsillitis sounds like no fun at all if you let it go untreated! From now on, if my throat ever starts feeling funny again, you can be sure I'll let my parents know immediately. Staying on top of your health is very important, even for kids. Getting check-ups and taking care of any issues right away is the key to staying healthy and happy!Well, that's the full scoop on my exciting trip to the doctor. Wasn't it a wild ride? I can't wait for my next doctor's visit adventure - I hear the lollipops they give out are the best! Thanks for reading, friends!篇6The 2013 Doctor English Test Was Really Hard!Hi everyone! My name is Timmy and I'm 8 years old. I really struggled with the 2013 national medical doctoral English unified exam this year. It was super duper difficult! I had to wake up at 6am to get to the test center by 8am. The test was scheduled from 8:30am to 5pm with just a short lunch break.That's a really long time for a kid to have to sit still and concentrate!The test had four sections - listening, reading, writing, and speaking. The listening section was first. We had to wear headphones and listen to conversations, lectures, and talks. Then we had to answer multiple choice questions about the main ideas, details, speaker's purposes, and making inferences. It was hard to pay attention the whole time without getting distracted!After listening, we moved right into the reading section. This part had really long and boring passages to read through. The passages were about all kinds of topics like science, history, culture, and academics. Some of the words were so advanced that I had never even heard them before! The questions asked about the main ideas, details, vocabulary, making inferences, and the author's views and purposes. My eyes started getting tired from all that reading.We then got a short lunch break, which was a nice break to rest my brain. But after lunch came the terrible writing section! We had to write two essays of different types, like an argument essay or a proposal essay. The prompt topics were really complex subjects that I didn't know much about. It was so hard to organize my thoughts and come up with enough supportingideas and examples to write a whole essay! My hand cramped up from all that writing.Finally after writing came the absolute worst part - the speaking section! We had to give spoken responses into a microphone about random topics and scenarios. I get so nervous speaking English out loud! We had to speak for 1-2 minutes on each question, using great vocabulary and organization. My mind just went blank under all that pressure. By the end, my mouth was dry from talking so much.This test was crazy difficult, way harder than anything we do in my regular English classes at school. I really hope I passed and don't have to take it again next year! I could barely stay awake driving home after the 9 hour exam. My brain felt like mush!Tests like this medical doctoral English exam seem way too hard for a little kid like me. How are adults even supposed to get through something so grueling and intense? Just thinking about it again makes me tired! I'll be happy if I never have to take another big standardized English exam for the rest of my life. No more essays, listening exercises, or speaking into microphones for me - I'm sticking to kids stuff from now on!。

Choose the bestanswer and mark the letter of your choice on the ANSWER SHEET.Passage OneChildren should avoid using mobile phones for all but essential calls because of possible health effects on young brains. This is one of the expected conclusions of an official government report to be published this week. The report is expected to call for the mobile phone industry to refrain from promoting phone use by children, and to start labeling phones with data on the amount of radiation they emit. The Independent Expert Group on Mobile Phones, chaired by former government chief scientist William Stewart, has spent eight months reviewing existing scientific evidence on all aspects of the health effects of using mobile phones. Its report is believed to conclude that because we don’t fully understand the nonthermal effects of radiation on human tissue, the government should adopt a precautionary approach, particularly in relation to children.There is currently no evidence that mobile phones harm users or people living near transmitter masts. But some studies show that cell-phones operating at radiation levels within current safety limits do have some sort of biological effect on the brain.to environmental insults,” he says,“So if phones did prove to be hazardous——which they haven’t yet ——it would be sensible.”In 1998, Tattersall showed that radiation levels similar to those emitted by mobile phones could alter signals from brain cells in slices of rat brain, “What we’ve found is an effect, but we don’t know if it’s hazardous,” he says.Alan Preece of the University of Bristol, who found last year that microwaves increase reaction times in test subjects, agreed that children’s exposure would be greater. “There’s a lot less tissue in the way, and the skill is thinner, so children’s heads are considerably closer,” he says.Stewart’s report is likely to recommend that the current British safety standards on energy emissions from cell-phones should be cut to the level recommended by the International Commission on Non-Ionizing Radiation Protection, which is one-fifth of the current British limit. “The extra safety factor of five is somewhat arbitrary,” s ays Michael Clark of the National Radiological Protection Board. “But we accept that it’s difficult for the UK to have different standards from an international body.”61. Just because it has not been confirmed yet whether mobile phone emissions can harm humantissue, according to the government report, does not mean that .A. the government should prohibit children from using cell-phonesB. we should put down the phone for the sake of safetyC. the industry can have a right to promote phone useD. children are safe using cell-phones62. Tattersall argues that it is wise to refrain mobile phone use by children in termsof .A. their neural developmentB. their ill-designed cell-phonesC. the frequency of their irrational useD. their ignorance of its possible health effects63. On the issue in question, Preece .A. does not agree with TattersallB. tries to remove the obstacles in the wayC. asks for further investigationD. would stand by Stewart64. What is worrisome at present is that the UK .A. is going to turn deaf ears to the voice of Stesart’s planB. finds it difficult to cut the current safety standards on phone useC. maintains different standards on safety limit from the international onesD. does not even impose safety limit on the mobile phones’ energy emissions65.Which of the following can bi the best candidate for the title of the passageA . Brain Wave B. For Adults OnlyC. Catch Them YoungD. The Answer in the AirPassage TwoAdvances in cosmetic dentistry and plastic surgery have made it possible to correct facial birth defects, repair damaged teeth and tissue, and prevent or greatly delay the onset of tooth decay and gum disease. As a result, more people smile more often and more openly today than ever in the past, and we can expect more smiles in the future.middle-class family members in formal portraits and domestic scenes appear to have their mouths firmly closed. Soldiers in battle, children at play, beggars, old people, and especially villains may have their mouths open; but their smiles are seldom attractive, and more often suggest strain or violence than joy.Smiles convey a wide range of meanings in different eras and cultures, says art historian Angus Trumble, currently curator(馆长)of Yale University’s Center for British Art, in his book A Brief History of the Smile. Compare, for instance, the varying impressions made by the shy dimples(酒窝)of Leonardo’s Mona Lisa; the rosy-cheeked, mustachioed Laughing Cavalier of Frans Hals; and the”Smiley Face”logo perfected(though not invented)in 1963 by American graphic artist Harvey .In some non-Western cultures, Trumble notes, even a warm, open smile does not necessarily indicate pleasure or agreement. It can simply be a polite mask to cover emotions considered too rude or shocking to bi openly displayed.Subtle differences in muscle movement can convey enormous differences in emotion, from the tranquility of bronze Buddhas, to the erotic bliss of couples entwined in stone on Hindu temples,to the fierce smirk(假笑)of a guardian demon at the entrance to a Chinese tomb.Trumble expects the impact of Western medicine and mass media to further increase the pressure on people to grin broadly and laugh openly in public.”Faint smiles are increasingly thought of in scientific and psychological circles as something that falls short of the true smile ,”and therefore suggest insincerity or lack of enthusiasm, he says.With tattooing, boby piercing, and permanent cosmetics already well established as fashion trends, one can imagine tomorrow’s beauty shops adding plastic surgeons and dentists to their staffs. These comer-store cosmeticians would offer style makeovers to reshape our lips, teeth, and jawlines to mimic the signature smile of one’s favorite celebrity.What can you say to that except” Have a nice day”66. Had it not been for cosmetic advances, as inferred from the passage, .A . people would not have been as happy as they are todayB. the rate of facial birth defect would not have declinedC . there would not have been many more open smilesD. we would not have seen smiling faces in public67. According to the passage, it seems that whether there is a smile or not in the portraits orpictures is decided by .A. one’s internal sense of the external worldB . one’s identity or social positionC . one’s times of existenceD . All of the above68. Trumble’s study on smiles shows that .A. an open smile can serve as a cover-upB . the famous portraits radiate varying smilesC. even the human muscles can arouse varying emotionsD. smiles can represent misinterpretations of different eras and cultures69. What Trumble expects to see is .A. the increasing tendency of broad grins and open smiles in publicB . further impact of Western medicine upon non-Western culturesC. a wider range of meanings to be conveyed by smilesD. more of sincerity and enthusiasm in public70 . At the end of the passage, the author implicates .C . future changes in life styleD . the future of smilesPassage ThreeAdolf Hitler survived an assassination attempt in 1944 with the lamp of penicillin made by the Allies, a microbiologist in the UK claims. If the Nazi leader had died from bacterial infection ofhis many wounds, the Second World War might have been over a year earlier, saving millions of lives, says Milton Wainwright of the University of Sheffield, a noted historian of microbiology.In a paper to be published soon in Perspectives in Biology and Medicine, Wainwright reveals first-hand evidence that Hitler was treated with penicillin by his personal doctor, Theo Morrell, following an assassination attempt in which a bomb in a suitcase exploded next to Hitler’s desk. Hitler was badly hurt, fleeing the scene with his hair and trousers on fire, a badly bleeding arm and countless wooden splinter wounds from the oak table that probably saved his life.Wainwright found confirmation that Morrell gave Hitler antibiotics as a precaution in a recent translation of Morrell’s own diary. “I happened to be reading it for interest when the word penicillin jumped out at me,” he says. He then set about trying to establish where Morrell might have got the drug.At the time, penicillin was available only to the Allies. German and Czechoslovakian teams had tried without much success to make it, Wainwright says, but the small quantities that weresays Wainwright. available were weak and impure. “It’s generally accepted that it was no good,”He reasons that Morrell would only have risked giving Hitler penicillin to prevent infectionsif he were confident that the antibiotic would cure, not kill the German premier. “My research shows that Morrell, in a very dodgy(危险的) position as Hitler’s doctor, would only have used pure stuff.” And the only reliable penicillin was that made by the Allies. So where did Morrell getitWainwright’s investigations revealed that Allied airmen carried penicillin, so the Germans may have confiscated some from prisoners of war. The other more likely source is from neutral countries such Spain, which received penicillin from Allied countries for humanitarian purposes, perhaps for treating sick children.have proof the Allies were sending it to these countries,” says Wainwright. “I’m saying “Ithis would have got through in diplomatic bags, reaching Hitler’s doctor and the higher echelons(阶层)of the Nazi party. So this was almost certainly pure, Allied penicillin.”“We can never be certain it saved Hitler’s life,” says Wainwright. But he notes that one of Hitler’s henchmen(死党),Reinhard Heydrich, died from blood poisoning after surviving acar-bomb assassination attempt. “Hair from his seat went into his wounds and gave him septicemia,” says Wainwright. Morrell may have been anxious to ensure that Hitler avoided the same fate.71. According to Wainwright, Adolf Hitler .A. might have used biological weapons in the warB. could not have committed suicide as confirmedC. could have died of bacterial infectionD. might have survived a bacterial plague72. Following his assassination in 1944, Adolf Hitler .A. began to exercise precautions against his personal attacksB. was anxious to have penicillin developed in his countryC. received an jinjection of penicillin for blood poisoningD. was suspected of being likely to get infecteds personal doctor .73. As Wainwright reasons, H itler’A. cannot have dared to prescribe German-made penicillin to himB. need not have used pure antibiotic for his suspect infectionC. would have had every reason to assassinate himD. must have tried to produce penicillin74. Wainwright implies that the Third Reich .A. met the fate of collapse as expectedB. butchered millions of lives on the earthC. was severely struck by bacterial plaguesD. did have channels to obtain pure penicillin75.Which of the following can be the best title for the passageA.How Hitler Manage to Survive Assassination AttemptsB.Morrell Loyal to His German PrimierC.Hitler Saved by Allied DrugsD.Penicillin Abused in GermanPassage FourGet ready for a new kind of machine at your local gym: one that doesn’t involve huffing and puffing as you burn off calories. Instead, all you have to do is stand still for 30 seconds while the machine measures your body fat. It could then tell you exactly where you could do with losing afew pounds and even advise you on exercises for your problem areas. If the body fat scanner turns out to be accurate enough, its makers hope it could one day help doctors spot disease.The scanner works by simultaneously building up an accurate 3D image of the body, while measuring the body’s effect on an electromagnetic field. Combining the two measurements allows the researchers to work out the distribution of fat and water within. Neither method is new on itsown, says Henri Tapp, at the Institute of Food Research in Norwich in the UK. “The smart thing is that we’ve put them in one machine.”And it’s not just for gym users. The body fat scanner could be used to study fat deposition as children develop, while patients recover from injury, or during pregnancy. And since it uses radio waves rather than X-rays, Tapp’s device is safe to use repeatedly.Body shape is known to be a risk indicator for heart disease and diabetes. So accurately quantifying fat distribution could help doctors suggest preventive measures to patients before problems arise. At the moment, doctors estimate fat content from knowing body volume and water content. To a good approximation, says Tapp, anything that isn’t fat is water. The amount of water in the body is often measured by giving the subject a drink of water that contains a radioactive tracer. The level of tracer in the patient's urine after three hours reveals the total water volume.To find out a body’s volume, subjects are weighed while totally submerged in water, and thisis subtracted from their normal weight to give the weight of water displaced, and hence the subject’s volume. But it is scarcely practical for seriously ill people.There are other ways to directly measure body fat, such as passing a minuscule current between the wrists and feet. The overall fat content can then be estimated from the body’s resistance. But this method doesn’t take body shape into account ——so a subject with particularly skinny legs might register a higher fat content than the true value. That’s because skinny legs—with a lower cross-sectional area——will present higher resistance to current. So the machine thinks the water content of the body is lower——rating the subject as fatter. Also, the system can only give an overall measurement of fat.Tapp’s method uses similar calculations, but is more sophisticated because it tells you where you are piling on the pounds.76. The new machine is designed .A. to picture the body’s hidden fatB. to identify those at risk for obesityC. to help clinically treat specific casesD. to measure accurately risky obesity-related effects77. The beauty of the device, according to Tapp, is that .A. it performs a dual functionB. it is of great accuracy in measurementC. it has significant implications in clinical practiceD. it contributes to the evolution of human anatomy78.Which of the following, according to the passage, does the machine have the potential tospareA. A minuscule current.B. A radioactive tracer.C. A water tank.D. All of the above.79.In comparison with the techniques mentioned in the passage, the body fat scanner .A. quickens the pace of the patient’s rehabilitationB. is highly appreciated for its safetyC. features its measuring precisionD. is easy to operate in the clinic80.For scanning, all the subject has to do is .A. take up a form of workout in the gymB. turn round the body fat scannerC. lie on the electromagnetic fieldD. sand in the systemPassage FiveThere is currently abroad a new wave of appreciation for breadth of knowledge. Curricula at universalities and colleges and programs in federal agencies extol(赞扬) the virtues of a broad education. For scientists who work in specialized jobs, it is a pleasure to escape in our spare timeto read broadly in fields distant from our own. Some of us have made interdisciplinary study our occupation, which is no surprise, because much of the intellectual action in our society today liesat the interfaces between traditional disciplines. Environmental science is a good example, because it frequently requires us to be conversant in several different sciences and even some unscientific fields.Experiencing this breadth of knowledge is stimulating, but so is delving deeply into a subject. Both are wonderful experiences that are complementary practical and aesthetic(美学的)ways. They are like viewing the marvelous sculpture of knowledge in two different ways. Look at the sculpture from one perspective and you see the piece in its entirety, how its components connect to give it form, balance, and symmetry. From another viewpoint you see its detail, depth, and mass. There is no need to choose between these two perspectives in art. To do so would subtract fromthe totality of the figure.So it is with science. Sometimes we gaze through a subject and are reluctant to stop for too much detail. As chemists, we are fascinated by computer sciences or molecular genetics, but not enough to become an expert. Or we may be interested in an analytical technique but not enough to stay at its cutting edge. At other times, we become immersed in the detail of a subject and see its beauty in an entirely different way than when we browse. It is as if we penetrate the surface of the sculpture and pass through the crystal structure to the molecular level where the code for the entire structure is revealed.Unfortunately, in our zeal for breadth or depth, we often feel that it is necessary to diminishthe value of the other. Specialists are sometimes ridiculed with names such as “nerd”or “technocrats”, generalists are often criticized for being too “soft” or knowing too little about any one thing. Both are ludicrous(可笑的) accusations that deny a part of the reality of。

大气窗口:由于大气对电磁波散射和吸收等因素的影响,使一部分波段的太阳辐射在大气中透过率很小或根本无法通过,电磁波辐射在大气传输中透过率较高的波段称为大气窗口。
大气窗口的位置、范围及有效性取决于大气中主要吸收气体的吸收光谱。
目前在遥感中使用的一些大气窗口为:1.0.3~1.15μm:包括部分紫外光、全部可见光和部分近红外光。
其中:0.3~0.4μm:透过率约为70%0.4~0.7μm:透过率大于95%0.7~1.1μm:透过率约为80%2.1.4~1.9μm:近红外窗口,透过率在60%~95%之间,其中1.55~1.75μm通过率较高3.2.0~2.5μm:近红外窗口,透过率为80%4.3.5~5.0μm:中红外窗口,透过率为60%~70%5.8.0~14.0μm:热红外窗口,透过率为80%6.1.0~1.8 mm:微波窗口,透过率约为35~40%左右7.2.0~ 5.0 mm:微波窗口,透过率在50~70%之间8.8.0~1000 mm:微波窗口,透过率为100%地物反射波(光)谱:指地物反射率随波长的变化规律。
基尔霍夫定律:一个物体的波谱发射率等于它的波谱吸收率,即好的吸收体也是好的发射体。
瑞利散射:由半径小于波长的1/10以下的微粒引起的散射叫瑞利散射(Reyleigh Scattering)漫反射:在物体表面的各个方向上都有反射能量的分布,这种反射称为漫反射。
波粒二象性:电磁波既表现出波动性,又表现出粒子性,即所谓的波粒二象性。
连续的波动性和不连续的粒子性是相互排斥、相互对立的;但二者又是相互联系的,在一定条件下可以相互转化。
电磁波谱:按电磁波在真空中波长或频率依顺序划分成波段,排列成谱即为电磁波谱。
地物反射波谱特性:地物波谱反射率随波长而改变的特性称之为地物反射波谱特性。
电磁辐射:当电磁振荡进入空间,变化的磁场激发了涡旋电场,使电磁振荡在空间传播,这就是电磁波,近代物理中,电磁波也称为电磁辐射。
电磁波是横波,在真空中以光速传播,满足:频率(f)×波长λ=光速(c)能量H=普朗克常数(h) *频率(f),电磁波具有波粒二象性。
程辐射(Path radiance): 遥感传感器中接收到的入射光中,除了在视场内地表反射光和地面热辐射外,大气的散射与自身辐射的光也进入传感器,这部分的光能量称作程辐射。
程辐射是背景噪声的主要来源。
空间分辨率(地面分辨率): 是针对遥感器或图像而言的,指图像上能够详细区分的最小单元的尺寸或大小,or遥感器区分两个目标的最小角度或线型距离的度量。
波谱分辨率:指传感器在接收目标辐射的波谱时能分辨的的最小波长间隔。
间隔越小,分辨率越高。
光谱分辨率:指遥感器所选用的波段数量的多少、各波段的波长位置及间隔的大小。
即选择的通道数、每个通道的中心波长、带宽,这三个因素共同决定光谱分辨率。
时间分辨率:指对同一地点进行遥感采样的时间间隔,即采样的时间频率,也称重访周期。
辐射分辨率:遥感器对光谱信号强弱的敏感程度、区分能力。
即探测器的灵敏度---遥感器感测元件在接收光谱信号时能分辨的最小辐射度差,或指对两个不同辐射源的辐射量的分辨能力。
一般用灰度的分级数来表示。
空间分辨率增大,辐射分辨率降低。
辐射传输方程:是指辐射源经大气层到达传感器的过程中电磁波能量变化的数学模型。
高光谱遥感:高分辨率遥感,它是在电磁波谱的可见光、近红外、中红外和热红外波段范围内,获取许多非常窄的光谱连续的影像数据的技术。
其成像光谱仪可以收集到上百个非常窄的光谱波段信息。
成象光谱仪:通常的的多波段扫描仪将可见光和红外波段分割成几个到十几个波段.对遥感而言,在一定波长范围内,被分割的波段数越多,即波谱取样点越多,愈接近连续波谱曲线,因此可以使得扫描仪在取得目标地物图像的同时也能获得该地物的光谱组成.这种既能成像又能获取目标光谱曲线的’谱象合一”的技术,称为成像光谱技术.按该原理制成的扫描仪称为成像光谱仪.监督分类:监督分类包括利用训练区样本建立判别函数的学习过程和把待分像元代入判别函数进行判别的过程。
监督分类的思想是:首先根据类别的先验知识确定判别函数和相应的判别准则,其中利用一定数量的已知类别的样本(称为训练样本)的观测值确定判别函数中待定参数的过程称之为学习或训练,然后将未知类别的样本的观测值代入判别函数,再依据判别准则对该样本的所属类别作出判定。
非监督分类:非监督分类的前提是假定遥感影像上同类物体在同样条件下具有相同的光谱信息特征。
非监督分类方法不必对影像地物获取先验知识,仅依靠影像上不同地物光谱信息进行特征提取,再统计特征的差别来达到分类的目的,最后对已分出的各个类别的实际属性进行确认。
在没有类别先验知识的情况下将所有样本划分为若干个类别的方法称之为非监督分类,也称聚类(clustering)。
最大似然分类:是经常使用的监督分类方法之一,它是通过求出每个象素对于各类别的归属概率,把该象素分到归属概率最大的类别中去的方法。
图像增强:传感器获取的遥感图像含有大量地物特征信息,在图像上这些地物特征信息以灰度形式表现出来,当地物特征间表现的灰度很小时,目视判读就无法辨认,而图像增强的方法可以突出显示这种微小灰度差的地物特征,图像增强的目的是为了改善遥感图像目视判读的视觉效果,以提高目视判读能力,它也是计算机自动分类的一种预处理方法。
图像增强的实质时增强感兴趣地物和周围地物图像间的反差。
图像增强的方法分为光学增强和数字增强方法两种。
混合像元:遥感图像像元记录的是探测单元的瞬时视场角所对应的地面范围内的目标的辐射能量的总和。
如果探测单元的瞬时视场角所对应的地面范围包含了多类不同性质的目标,则该像元记录的是多类不同性质的地面目标的辐射能量的总和,这样的像元称为混合像元。
全球定位系统:是利用多颗导航卫星的无线电信号,对地球表面某地点进行定位、报时和对地表移动物体进行导航的技术系统。
遥感平台:遥感中搭载传感器的工具称为遥感平台,按高度可分为地面平台、航空平台、航天平台。
大气纠正:太阳光在到达地面目标之前,大气会对其产生吸收和散射作用。
同样,来自目标地物的反射光和散射光在到达传感器之前也会被吸收和散射。
入射到传感器的电磁波能量除了地物本身的辐射以外还有大气引起的散射光,消除这些影响的处理过程称为大气校正。
校正的方法有:利用辐射方程进行大气校正;利用地面实况数据进行大气校正;利用辅助数据进行大气校正。
密度分割:在一张黑白遥感图像上,随地物的反射(或发射)电磁波强度的不同将有所不同的密度分布.如果在图像的最大密度和最小密度之间,人为地分成许多区间,并且将某一区间用同一种密度或同一种颜色表示,不同区间则用不同密度或不同颜色表示,我们称之为密度分割.中心投影:地物任一点A 与空间固定点S 的连线被某一平面p 截获,其交点 a 即称为A 在平面p 上的投影。
