A study has showed that the brain makes decisions about 10 se conds before a person realizes it.Experts involved in the study said that looking at brain activity w hile making a decision,they could predict the choices the subjects would make, before they realized that they had made a decision. Lead researcher J ohn-Dylan Haynes, a neuroscientist (神经学家)at the Max Planck Institute for Human Cognitive and Brain S ciences in Leipzig, said that the new findings called into questio ns for “consciousness”of decisions that people make, and might even challenge ideas as to how“free”people are to make a deci sion at a particular moment.“We think our decisions are conscious, but these data show tha t consciousness is just the tip of the iceberg,”Nature magazine quoted (引用) him as saying. Thinking the results“quite dramatic”, Frank T ong of Vanderbilt University in , , said that 10 seconds is“a lifetime”in terms of brain activity.During the study, the brains of 14 volunteers were imaged as th ey performed a decision-making task. The subjects had two buttons before them, each t o be operated by a different hand, which they could press when they felt the urge to. They were sim ultaneously (同时地)shown a stream of letters, which appeared on a screen at ha lf-second intervals (间隔). The volunteers had to remember which letter was showing when they decided to press their button.Upon analysis of the data, the researchers realized that the earl iest signal they could catch started seven seconds before the v olunteers reported having made their decision. Given the delay of a few seconds in the imaging, they reckoned (估计) that the brain activity could have begun about ten seconds b efore the conscious decision. The researchers showed that the signals were picked up from a region (区域)called the frontopolar cortex (脑额极皮层),which is located at the front of the brain, immediately behind the forehead.While writing about the observations made during the research i n his study report, Haynes said that the frontopolar cormight be the brain region where decisions are started. He also showed that the next step in the research would be to speed up the data analysis so as to enable his team to predict people’s c hoices as their brains would make them.1. The passage tells us that ______.A. we are aware of our whole process of decision-makingB. people don’t make decisions until they realize itC. experts have no way to tell what decision one will makeD. the decision-making process starts before it is made2. The underlined word “subjects”in Para. 2 probably refers to _ _____.A. the topic of the experts’ research paperB. the scientific subjects that the experts were studyingC. the things that experts don’t know clearlyD. the volunteers that the experts worked on for their research3. The underlined sentence“consciousness is just the tip of the i ceberg”in Para. 4 means that ______.A. our decision-making is consciousB. the data contains a lot of information besides consciousnessC. consciousness is the major part of the dataD. 10 seconds is“a lifetime”in terms of brain activity4. The final purpose of the research ______.A. is not stated clearly in the passageB. is not acknowledged by expertsC. is to show where decision-making startsD. is to analyze the data picked up5. The passage implies that ______.A. the research has been completedB. the research was conducted by two expertsC. the decision-making process lasts only about 10 secondsD. we may predict what decisions people will make in the future 【参考答案】25.DDBA【四川省成都市2014届高三英语摸底测试模拟试题（一）】Humans are naturally drawn to other life forms and the worlds o utside of our own. Wetake delight in the existence of creatures and even whole societ ies beyond our everyday lives.This sense of wonder is universal. Look at the efforts that scient ists have made to find out whether life of some kind exists on Mars, and the popularity of fantasy literature or movies like The L ord of the Rings. This sense of wonder draws us to each other, to the world around us, and to the world of make-believe. But have we gone so far in creating worlds of fantasy t hat we are missing the pleasure of other worlds that already exi st all around us?Human beings, as biologists have suggested, possess an inbor n desire to connect with and understand other life forms, Howev er, people, especially in big cities, often lead rather isolated live s. In a study of British schoolchildren, it was found that children by age eight were much more familiar with characters from tele vision shows and video games than with common wildlife. With out modern technology, a small pond could be an amazing worl d filled with strange and beautiful plants, insects, birds, and ani mals. When we lack meaningful interaction with the world aroun d us, and sometimes even with our families and friends, we see k to understand and communicate with things that exist only in our imaginations or on a computer screen.The world of make—believe is not necessarily bad. But when the world of fantasy be comes the only outlet for our sense of wonder, then we are reall y missing something. We are missing a connection with the livin g world. Other wonderful worlds exist all around us. But even more interesting is that if we look closely enough, we can see that these worlds, in a broad sense, are really part of our own.47.The popularity of The Lord of the Rings proves _____.A. the close connection between man and the fantasy worldB. the wonderful achievements of fantasy literatureC. the fine taste of moviegoers around the worldD. the general existence of the sense of curiosity48.What can we infer from the underlined sentence in Paragraph 3?A. People are far less familiar with the world of fantasy.B. The world around us could serve as a sound of wonder.C. The world of fantasy can be mirrored by a small and lively pond.D. Modern technology prevents us from developing our sense of wonder.49.If our sense of wonder relies totally on the world of make—believe, we will _____.A. fail to appreciate the joy in our livesB. be confused by the world of make—believeC. miss the chance to recognize the fantasy worldD. be trapped by other worlds existing all around us50.What is the main purpose of the passage?A. To show us the hidden beauty in our world.B. To warn us not to get lost in the fantasy world.C. To argue against the misuse of the sense of wonder.D. To discuss the influence of the world of make—believe.47. D 48.B49.A50.B[【上海市闵行区2014高考英语质量调研考试】Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For e ach of them there are four choices marked A, B, C and D. Choo se the one that fits best according to the information given in th e passage you have just read.(A)Foxes and farmers have never got on well. These small dog-like animals have long been accused of killing farm animals. Th ey are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them.Farmers can also call on the services of their local hunt to control the fox population. Hunting consists of pursuing a fox across the countryside, with a group of specially trained dogs, followed by men and women r iding horses. When the dogs eventually catch the fox they kill it or a hunter shoots it.People who take part in hunting think of it as a sport; they wear a special uniform of red coats and white trousers, and follow strict codes of behavior. But owning a horse and hunting re gularly is expensive, so most hunters are wealthy.It is estimated that up to 100,000 people watch or take part in fo x hunting. But over the last couple of decades the number of pe ople opposed to fox hunting, because they think it is cruel, has r isen sharply. Nowadays it is rare for a hunt to pass off without s ome kind of conflict between hunters and hunt saboteurs (阻拦者). Sometimes these incidents lead to violence, but mostly sab oteurs interfere (干涉) with the hunt by misleading riders and disturbing the trail of t he fox’s smell, which the dogs follow.Noisy conflicts between hunters and saboteurs have become s o common that they are almost as much a part of hunting as th e pursuit of foxes itself. But this year supporters of fox hunting face a much bigger threat to their sport. A Labour Party Member of the Parliament, Mike Foster, is trying to get Parliament to ap prove a new law which will make the hunting of wild animals wit h dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in .66. Rich people in Britain have been hunting foxes ________.A. for recreationB. to limit the fox populationC. in the interests of the farmersD. to show off their wealth67. What is special about fox hunting in Britain?A. It involves the use of a deadly poison.B. It is a costly event that rarely occurs.C. The hunters have set rules to follow.D. The hunters have to go through strict training.68. Fox hunting opponents often interfere in the game ____ ____.A. by leaning upon violenceB. by taking legal actionC. by confusing the fox huntersD. by demonstrating on the scene69. A new law may be passed by the British Parliament to ________.A. prohibit farmers from hunting foxesB. forbid hunting foxes with dogsC. stop hunting wild animals in the countrysideD. prevent large-scale fox hunting6 6.A67.C68.C69.BIntellectual property (IP) is a product of the mind that has comm ercial value．The concept dates back to 1623,when the first pat ent law to protect IP rights was passed．IP rights protect an arti st from having his/her creative ideas copied by another．For ex ample, if somebody generates an idea for a novel, that idea is p rotected by IP rights．If someone else wishes to represent the i dea or develop it further, he/she must consult the original artists , who will normally be rewarded financially for its use．Back in t he 17th century, IP rights were primarily carried out to protect n ewly developed manufacturing processes against stealing, but t oday, intellectual property rights, are also enjoyed by those who create music, art and literature．In recent years, IP rights have been the focus of a great deal of discussion because of a technology which looks set to weaken t hem altogether: the Internet．Many years ago, if you wanted a recording of a song, you would have to purchase it from a musi c store; if a novel, from a book store．In those days, IP rights w ere easily protected since it was very difficult to obtain intellectu al property without paying for it．However, a lot of IP, including songs, films, books and artwork, can be downloaded today free of charge using the Internet．This practice has now taken the w orld by storm, dramatically affecting the way in which we view I P rights．68．According to the writer, in the beginning, IP rights were mai nly of use to ____ __．A．those creating music, art and literatureB．novelistsC．engineers and inventorsD．those not receiving financial reward for their work 69．What do we know about the Internet according to the pass age?A．It makes IP rights harder to protect．B．It sells songs and films．C．It does not affect the way we understand IP rights．D．It prevents the production of artwork．70．According to Paragraph 2, what has “taken the world by st orm”?A．Intellectual property rights． B．The Internet．C．Free downloading． D．The large number of songs, fi lms and books．71．A possible title for this passage could be _____ _．A．A History of IP Rights B．Ways to Protect Your IP RightsC．The Present and the Future of IP D．IP Rights and O ur Attitudes参考答案 68.C 69.A 70.C 71.D阅读理解A friend of mine named Paul received an expensive car from hi s brother as a Christmas present. On Christmas Eve when Paul came out of his office, a street urchin (顽童)was walking around the shining car. "Is this your car, Paul?"he asked.Paul answered, "Yes, my brother gave it to me for Christmas." The boy was surprised. "You mean your brother gave it to you a nd it didn't cost you anything. Boy, I wish..."He hesitated (犹豫). Of course Paul knew what he was going to wish for. He was goi ng to wish he had a brother like that. But what the boy said surp rised Paul greatly."I wish," the boy went on, "that I could be a brother like that." Pa ul looked at the boy in surprise, then he said again; "Would you like to take a ride in my car?" "Oh, yes, I'd love that." After a sho rt ride, the boy turned and with his eyes shining, said, "Paul, wo uld you mind driving in front of my house?"Paul smiled a little. He thought he knew what the boy wanted. H e wanted to show his neighbors that he could ride home in a big car. But Paul was wrong again. "Will you stop where those two steps are?" the boy asked.He ran up to the steps. Then in a short while Paul heard him co ming back, but he was not coming fast. He was carrying his littl e crippled ( 残疾 ) brother. He sat him down on the step and pointed to the car ."There he is, Buddy, just like I told you upstairs. His brother gav e it to him for Christmas and it didn't cost him a cent. And someday I'm going to give you one just like it. Then youcan see for yourself all the nice things in the Christmas window that I've been trying to tell you about."Paul got out and lifted the boy to the front seat of his car. The s hining-eyed older brother climbed in beside him and three of them beg an an unforgettable holiday ride.67. The street urchin was very surprised when______________ .A. Paul received an expensive carB. Paul told him about the carC. he saw the shining carD. he was walking arou nd the car68.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. Choose the one that fits best according to the information given in the passage.AKarl Fleming joined the military because he needed a change in his life. He had a successful career with a shipping company but he wanted to do something more. He found that something in the U.S. army. Fleming began his service in 2009 and never looked back.A few years later, Fleming volunteered to go to Afghanistan. There, he worked as a bodyguard for the U.S. Army Corps of Engineers. He enjoyed it, except for the almost-nightly rocket attacks. Karl was never hit di rectly by a rocket, but he didn’t need to be to feel its effects. The rockets caused severe shaking, shaking so bad that Fleming was left with many injuries. He was also diagnosed with concussions(脑震荡) and Post-Traumatic Stress Disorder(PTSD).Fleming said he was down but not out. Once he returned from Afghanistan, Fleming underwent one test after another. At first, Fleming said he thought he could recover or be able to return to duty and realize his dream of becoming an officer. But then came the news he had never imagined: Fleming would never be an officer because he was too injured to continue.Fleming said he was depressed after learning his military career was over. Add that to the memory loss, extreme anxiety and the many painful medical procedures he was already experiencing. He rarely ventured outside on the weekend. Instead, he preferred to sleep in. All that changed, however, with Fleming’s service dog, Kuchar.Fleming said he had heard dogs could help people suffering from PTSD, so he started doing research. Karl eventually selected K9s for Warriors, which is where he met Kuchar, a yellow lab. Fleming and Kuchar trained together for weeks, before returning to Fort Benning. K9s for Warriors provided Fleming with Kuchar and the training for free.Life with Kuchar has been life-changing. Fleming doesn’t sleep in any more because Kuchar won’t let him. Instead, they venture out into a world Karl was once afraid of — a world for Fleming that now seems impossible to imagine without Kuchar by his side.56. Karl Fleming joined the army because ___________.A. he had a successful careerB. he loved to be a soldierC. he wanted to have a changeD. he expected to work in a shipping company57. From Paragraph 2, we can learn Karl Fleming was __________.A. forced to go to AfghanistanB. struck directly by a rocket one dayC. satisfied with everything in the armyD. injured because of the shaking from the rockets58. Fleming suffered from the following illnesses except ___________.A. concussionsB. PTSDC. memory lossD. a heart attack59. Karl Fleming recovered with the help of ___________.A. an experienced bodyguardB. a well-trained dogC. a laboratory engineerD. a military officer60. The passage is mainly about Fleming’s__________.A. change of lifeB. service in the militaryC. medical proceduresD. experiences in AfghanistanBThe snow cap of Mount Kilimanjaro, famous in literature and beloved by tourists, initially formed some 11,000 years ago, but will be gone in two decades, according to researchers who say the ice fields on Africa’s highest mountain shrank by 80 percent in the past century.Lonnie G. Thompson, one professor from Ohio State University, said measurements using modern navigation satellites show that the oldest ice layers on the famous mountain were deposited during an extremely wet period starting about 11,700 years ago. The mountain appears in literature,most notably Ernest Hemingway’s “The Snows of Kilimanjaro” and some ancient beliefs in Africa hold the mountain to be a sacred place.But a temperature rise in recent years is destroying the 150-foot-high blocks of ice that gave Kilimanjaro its unique white cap. “The ice will be gone by about 2030,” said Thompson. The disappearing ice already has reduced the amount of water in some Tanzanian rivers and the government fears that when Kilimanjaro is bald of snow the tourists will stop coming.“Kilimanjaro is the number one foreign currency earner for the government of Tanzania,” said Thompson. “It has its own international airport and some 20,000 tourists every year. The question is how many will come if there ar e no ice fields on the mountain.”Africa was not alone in the global drought. Thompson said other records show that civilizations during this period collapsed in India, the Middle East and South America.Researchers put markers on the ice field blocks in 1962 and Thompson said measurements using satellites show the summit of the ice has been lowered by about 56 feet in 40 years. The margin of the ice also has moved back more than six feet in the past two years, much smaller than before.“That’s more than tw o meter’s worth of ice lost from a wall 164 feet (50 meters) high,” said Thompson. “That’s an enormous amount of ice.”61. The snow cap of Mount Kilimanjaro ________.A. will disappear in two centuriesB. first developed some 11,000 years agoC. resulted in a temperature rise in recent yearsD. has decreased to 80 percent over the past century62. According to Thompson, the disappearing of the snow may mainly influence________.A. the local water supplyB. the local tourismC. the weather in the surrounding areasD. the government foreign currency exchange63. The underlined word“margin” in Paragraph 6 means__________.A. centerB. topC. edgeD. back64. The writer’s tone in this article is___________.A. concernedB. casualC. doubtfulD. angry65. Which of the following can be the best title for this passage?A. Risks of Visiting Mount KilimanjaroB. A Sacred Place— KilimanjaroC. Africa’s Highest Mountai nD. Kilimanjaro Snow Cap May Melt SoonCHow many times a day do you check your email? When you wake up? Before bed? A dozen times in between? The technology that was supposed to simplify our lives has become the vital time-suck: the average teen spends more than seven hours a day using technological devices, plus an additional hour just text-messaging friends.The advantage of technological devices is connectedness: email lets us respond on the go, and we are in touch with more people during more hours of the day than at any other time in history. But is it possible we’re more lonely than ever, too? That’s what MIT professor Sherry Turkle observes in her new book, Alone Together, a fascinating portrait of our changing relationship with technology. Turkle details the ways technology has redefined our comprehension of closeness and loneliness—and warns us of the danger of accepting such virtual(虚拟的) relationships in place of lasting emotional connections.For Turkle, the biggest worry is the effect all these shallow connections have on our development. Is technology offering us the lives we want to live? “We’re texting people at a distance,” says Turkle, “We’re using lifeless objects to convince ourselves that even when we’re alone, we feel together. And then when we’re with each other, we put ourselves in situations where we are alone—constantly on our mobile devices. It’s what I call a perfect storm of confusion about what’s important in our human connections.”What can’t be denied is that technology, whatever its faults, makes life a whole lot easier. It allows us to communicate with more people in less time and makes conversation simple. But it can also be seductive(具有诱惑性的), providing more stimulation than our natural lives. There are usually some unhealthy videos online which remove teenagers’ attention from their schoolwork. Besides, some online activities make people addicted, which occupied their daily life and affected their ability to form real-world relationships. “Technology can be more immediately satisfying than the labor of building an intima te relationship,” said one high school student, “Every time I text, I start to have some hap py feelings.”But are any of those feelings equal to the kind we feel when engaged in real, face-to-face communication? Online, you can neglect others’ feelings. In a text message, you can avoid eye contact. A number of studies have found that this generation of teens is less sympathetic than ever. That doesn’t spell disaster, says Turkle—but it does mean we might want to start thinking about the way we want to live.66. From the first paragraph we can infer that_________.A. email checking helps people wake up earlyB. technological device production has been simplifiedC. using technological devices costs teens much timeD. people communicate mainly by text-messaging now67. Turkle’s new book mainly discussed________.A. ways to draw a fascinating portraitB. how technology influences human relationshipsC. the dangers of accepting emotional connectionsD. the advantages of technology68. What worries Turkle most is that more and more people are_________.A. starting to accept emotional connections in place of virtual connectionsB. convincing themselves by using fewer lifeless objects in connectionsC. dropping the use of technological devices for connection with each otherD. being affected by the shallow connections through the mobile devices69. Which of the following is True according to the passage?A. Others’ feeling s can be ignored in online communication.B. No stimulation is provided in natural life connections.C. People always send text messages to avoid eye contact.D. It may be a disaster that teens are less sympathetic than ever.70. What is the main purpose of the passage?A. To instruct people how to do with emails.B. To stress the importance of technology.C. To promote a wider use of technological devices.D. To lead us to consider what’s important in human connection s.Part IV Writing (45 marks)Section A (10 marks )Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage.Write NO MORE THAN THREE WORDS for each answer.A consumer complaint or customer complaint is an expression of dissatisfaction on a consumer’s behalf to a responsible party. It can also be described in a positive sense as a report from a consumer providing documentation about problems with a product or service.So what are the common reasons for customer complaints? The most common complaints about retail(零售) stores fall into several aspects. First, they have to circle the filled parking lot endlessly, which is a waste of time and a test for their patience. They also can’t stand cluttered shelves, over-loaded racks, out-of-stock items and long check-out lines. Worst of all, sometimes some salespeople are rude, turning their mood into a bad one.In fact, some modern business consultants urge businesses to view customer complaints as a gift but not a trouble. Some retailers, however,ignore complaints or deal with them dishonestly,which can cause a chain of events like bad reputation, leave their business with fewer and fewer customers. The resulting “snowball effect” can be disastrous to retailers. In the most severe cases, it can even cause companies to shut down.Increasing competition is forcing companies to take more effective measures to satisfy customers and better their customer service. During peak shopping hours, some moonlighting(业余兼职的) local police have been employed as parking attendants by some retailers to solve the parking problems. Some hire flag wavers to direct customers to parking spaces that are empty. This guidance can avoid confrontation between those eyeing the same parking space. Retailers can relieve the headache by redesigning store layouts, pre-stocking sales items, hiring the cashiers with much experience, and having sales representatives on hand to answer questions. Most importantly, salespeople should be trained to deal with angry customers with politeness.Try their best to resolve the problem if they can.Quickly and properly solving customer complaints can help retailers smooth over issues and their business can grow and prosper.Title: 71.______Definition72. _______73. _______●an expression of consumers’ dissatisfaction●74. __________ on a problem with a product or serviceFilled parking lots, cluttered shelves, over-loaded racks,out-of-stock items, long check-out lines and 75. ________●77. ________ as parking attendants●Hiring flag wavers to direct customers to 78. ________●Redesigning store layouts and pre-stocking sales items●Hiring 79. ____________●Having sales representatives answer questions●Training salespeople to deal with angrycustomers80._____________Effects bad reputation →76.________→companies shutting downSection B (10 marks)Directions: Read the following passage. Answer the questions according to the information given in the passage.My grandmother was a master gardener that could make anything bloom. Even me.She spent most of her life living on a farm in the mountains of North Caroline, where she got married, raised four children, and watched the changing of the seasons. When I was 12 years old, my dad gave up working downtown and moved back to the farm to turn to gardening. I visited on weekends to keep them company.Every time my farm chores were done, I was free to climb the mountain, singing songs and gathering flowers. Sometimes the plants scratched me. My grandmother would say: “Beauty has a price. I hope it was worth it.” I would say, “Yes, ma’am. It was.” Then I’d scratch some more. At dusk, we’d sort the flowers and make bouquets(花束): One for the living room, one for the kitchen, and three for the bedrooms.Even then as a child, I knew that what I desired most from my grandmother was not her flowers but her time. She has been gone for decades, but sometimes when I reach down to pick a flower or pull a weed, I see her hand, not mine. I thought I’d grow up to be a gardener as well. I informed myself, someday, when my children had children，I would be a gardening grandma. Then the grandbabies started showing up, and I discovered I would much rather chase after them than go digging.The truth is, I’m no gardener. I’m a picker, not a planter. I don’t need to plant a garden. My children are my flowers. They delight me and complete me with a beauty that is worth any price.My grandmother and I differ in lots of ways, but from her, I do learn what a grandmother means.I also learn that I need attend to my grandbabies with time and water them with love. I hope that, one day, when they hold their first grandchild, they might see my hand.81.
