by Paul TherouxChoosing my favorite Paul Theroux book is like picking my favorite place in the world：It's impossible to settle on just one．But The Old Patagonian Express，which is about a train journey Theroux made from Boston，USA to southern Argentina，is right up there at the top of my list．Theroux has a wicked sense of humor．He brings so much wisdom and experience to his travels．Walden by Henry David ThoreauIf he were alive today，Thoreau would probably frown if he heard someone refer to Walden as a travel book．But I regard it as a travel﹣writing masterpiece．"I went into the woods，"he writes，"because I wished to live deliberately，to front only the essential facts of life，and see if I could not learn what it had to teach，and not，when I came to die，discover that I had not lived．"That's the same spirit of discovery that defines so many great contemporary travel records．The Dharma Bums by Jack KerouacLike so many people，I fell in love with Kerouac's novels in my late teens and early 20s．On the Road gets all the press，but I always love The Dharma Bums．Kerouac beautifully captures the romance of California trains，Berkeley，and backpacking in the Sierras．It's hard to read this book without wanting to leave for the mountains to brainstorm bad haikus on the trail and cook canned macaroni and cheese over a crackling campfire．Confucius Lives Next Door by T．R．ReidThis is sort of A Year in Provence in Japan，only the cross﹣cultural differences are much greater．Reid and his family moved to Tokyo when he became the chief for The Washington Post，enabling him to uncover truths about the country．Among the highlights are his observations about Japanese schools，including Yodobashi No.6Elementary School，where his daughters were greeted by the whole school staff．21．Which book enables readers to experience great cross﹣cultural differences？A．The Old Patagonian Express．B．Confucius Lives Next Door．C．On the Road．D．Walden．22．What will people feel after reading Jack Kerouac's The Dharma Bums？A．A strong desire to follow．B．A love for novels．C．A wish to learn cooking．D．An excitement to write poems．23．Which writer based his book on a train journey from home to abroad？A．T．R．Reid．B．Henry David Thoreau．C．Paul Theroux．D．Jack Kerouac．24．What features most modern travel books according to the author？A．Experience．B．Observation．C．Culture．D．Discovery．25．Henrietta Lacks was born in 1920 in Virginia and raised on a tobacco farm．She married her first cousin，David Day and later settled near Baltimore in Turner Station where Day worked at a steel mill．After giving birth to her fifth child，she was diagnosed with cervical cancer．She was treated at Johns Hopkins，the only hospital within twenty miles that treated black patients and had been established as a charity hospital．In an attempt to grow everlasting cells，Dr．George Gey took samples of all women who came to Hopkins with cervical cancer．After taking a biopsy （活检） of Henrietta's cervical cancer，researcher Dr．George Gey discovered that unlike any cells they had seen before，Henrietta's cells could not only reproduce，but thrive outside the body﹣﹣a breakthrough that would change modern medicine．Actually，her cells doubled in size every 24 hours and Dr．Gey shared these cells for free with any researcher interested．Later，Dr．Stanley Gartler found that Henrietta's cells were even capable of jumping out of the petri dish（培养皿） and taking other cell types．As a result，these cells，named HeLa（for Henrietta Lacks） were essential in the research into cancer，AIDS，the effects of radiation and poisonous substances，gene mapping，and countless other scientific pursuits．And they've been used in tens of thousands of research studies．Ms．Lacks died not too long after her diagnosis in 1951．She unknowingly held the key to unlocking medical advancements in her tumor cells．Now，decades after Henrietta's death，her cells are still alive．For many years，her family knew nothing about the impact her cells had on medical science﹣she provided a crucial sample of cells that has furthered the knowledge of medical science and disease prevention． Now nearly 60years after her death，in May 2011，Morgan State University in Baltimore awarded her an honorary degree．25．What is the passage mainly about？A．A woman's contribution to medical progress．B．The contribution of Johns Hopkins．C．The original research of cancer．D．The death of a black patient．26．Which word can describe the cells of Henrietta Lacks？A．Radioactive．B．Poisonous．C．Active．D．Interesting．27．What does the underlined word"thrive"mean probably？A．Die．B．Grow．C．Break．D．Change．28．The book Outliers makes a list of the seventy﹣five richest people in history． Do you know what's interesting about that list？Of the 75 names，an astonishing 14are Americans born within nine years of each other in the mid 19th century．Think about that for a moment．Historians start with Cleopatra and the Pharaohs and comb through every year in human history ever since，looking in every corner of the world for evidence of extraordinary wealth，and almost 20percent of the names they end up with come from a single generation in a single country．Here's the list：What's going on here？The answer is obvious，if you think about it．In the 1860's and 1870's，the American economy went through perhaps the greatest transformation in its history．This was when the railways were built，and when Wall Street emerged．It was when industrial manufacturing started properly．It was when all the rules by which the traditional economy functioned were broken and remade．What that list says is that it really matters how old you were when that transformation happened． If you were born in the late 1840's，you missed it．You were too young to take advantage of that moment．If you were born in the 1820's，you were too old：your mindset was shaped by the pre﹣Civil War pattern．But there is a particular，narrow nine﹣year window that was just perfect for seeing the potential that the future held．All of the 14 men and women on that list had vision and talent．But they also were given an extraordinary opportunity．28．What does the author think of the fact that 14 of the 75 richest people were born in USA？A．Surprising．B．Exciting．C．Unfair．D．Proud．29．What does the author think leads to the great wealth of the richest people in the USA？A．Their strong hardwork．B．Their talented mindset．C．The industrial tradition．D．The economic transformation．30．What does the author think is the most important to the 14 richest Americans in the last paragraph？A．Talent．B．Vision．C．Opportunity．D．Potential．31．What is right about the 14 American﹣born richest people on the list？A．They were chosen throughout USA．B．They were born from 1831 to 1840．C．They were shaped by the Civil war．D．They were interesting and wealthy．32．About 100 years ago the horse﹣manure（马粪） crisis drove most observers to despair.19th﹣century cities depended on horses for daily functioning．In New York in 1900，100，000 horses were used in all transport，and in delivering the goods needed by the growing population．The problem was that all these horses produced huge amounts of manure．A horse on average produces 15﹣35 pounds of manure per day．Consequently，the streets of 19th﹣century cities were covered by horse manure．This，in turn，attracted huge numbers of flies，and the dried manure was blown everywhere．Every day 2.5 million pounds of horse manure were produced and had to be swept up and disposed of．In 1898 the first international urban﹣planning conference was held in New York．It was abandoned after three days，instead of the scheduled ten，because nobody could see any solution to the growing crisis by urban horses and their output． The problem did seem tough．The larger and richer that cities became，the more horses they needed．The more horses，the more manure．In 1894，a writer estimated that in 50 years every street in London would be buried under nine feet of manure．Moreover，all these horses had to be stabled，which used up ever﹣larger areas of increasingly valuable land．And as the number of horses grew，ever﹣more land had to be devoted to producing hay to feed them （rather than producing food for people），and this had to be brought into cities and distributed﹣by horse﹣drawn vehicles．It seemed that urban civilization was doomed．Of course，urban civilization was not buried in manure．Because millions of horses were replaced by motor vehicles!This was possible because of cleverness of inventors and entrepreneurs such as Gottlieb Daimler and Henry Ford，and a system that gave them the freedom to put their ideas into practice．Even more important，however，was the existence of the price mechanism．When the price of horse﹣drawn transport rose steadily with the increasing cost of feeding and housing horses，strongincentives（动机） were created for people to find alternatives．32．How would you feel if you were walking on the New York street of 1900？A．Sick．B．Light﹣hearted．C．Excited．D．Satisfied．33．What was the problem that New York faced one hundred years ago？A．Heavy traffic．B．Narrow streets．C．Little valuable land．D．Horse manure．34．What was the probable target of the first international urban﹣planning conference in 1898？A．To feed more horses．B．To find a solution to horse manure．C．To reduce public buses．D．To produce motor vehicles．35．What was the most important factor in solving the urban civilization problem of New York？A．Entrepreneurs'freedom．B．People's incentives．C．Price mechanism．D．Government's appeal．第二节（满分10 分）36．根据短文内容，从短文后的选项中选出能填入空白处的最佳选项．选项中有两项为多余选项．Snowblind﹣﹣it's a frightening word．Thankfully，it's a condition that is totally preventable．Snow blindness is a painful，temporary loss of vision due to overexposure to the sun's UV rays．Essentially，snow blindness is caused by a sunburned eye．（36）Though it is commonly called snow blindness，the condition can （and often does） occur in the absence of snow．The terms"snowblind"and"snow blindness"have become popular because snow is highly reflective of ultraviolet radiation．（37） Also，skiing，mountain climbingand snowboarding usually take place at relatively high altitudes，where the sun's UV rays are stronger．Combined，these factors can double your risk of getting sunburned eyes，compared with being outdoors at lower altitudes in the summertime．（38）Television journalist Anderson Cooper experienced snow﹣free snow blindness first﹣hand a few years ago when he spent a couple hours on a boat in Portugal without sunglasses and ended up"blind for 36hours，"according to his report of the incident．Not only can you become snowblind without snow﹣﹣it can happen without sunlight，too!（39）For example，sun lamps can cause temporary"snow"blindness if proper eye protection is not used．（40）To relieve pain or discomfort from snow blindness，stay indoors and wear sunglasses．Keep your eyes well﹣moistened with artificial tears．For additional relief，use over﹣the﹣counter pain relievers．Be sure to use only pain relievers you know you can take without worry of an allergic reaction．You also may find that placing a cool，dampened washcloth over your closed eyelids is comforting．A．You don't need snow to become snowblind．B．It will likely affect those traveling in snowy conditions．C．To prevent snow blindness on the slopes，wear sunglasses．D．Sometimes it occurs from man﹣made sources of ultraviolet radiationE..In fact，snow can reflect over 80percent of the UV rays that fall upon it．F．Snow blindness is scary，but usually it's temporary，and there are ways to relieve the discomfort．G．But water and white sand also are highly reflective of the sun's UV rays，thus increasing the risk．第三部分：英语知识运用（共两节，满分45分）41．第一节：完形填空There was a businessman who was deep in debt and could see no way out．He sat on the park bench，head in hands，（41） if anything could save hiscompany from

escaping from the rest home and telling people he's John D．Rockefeller．"And she led the old man away （56） the arm．The businessman just stood there，（57）．All year long he'd been buying and selling，（58） he had half a million dollars behind him．Suddenly，he realized that it wasn't the money，real or （59），that had turned his life around．It was his （60） self﹣confidence that gave him the power to achieve anything he went after．41．A．wondering B．suspecting C．estimating D．hesitating 42．A．attacking B．disturbing C．interrupting D．amusing 43．A．number B．note C．letter D．check 44．A．calmly B．quietly C．quickly

bad haikus on the trail and cook canned macaroni and cheese over a crackling campfire．Confucius Lives Next Door by T．R．ReidThis is sort of A Year in Provence in Japan，only the cross﹣cultural differences are much greater．Reid and his family moved to Tokyo when he became the chief for The Washington Post，enabling him to uncover truths about the country．Among the highlights are his observations about Japanese schools，including Yodobashi No.6Elementary School，where his daughters were greeted by the whole school staff．21．Which book enables readers to experience great

cross﹣cultural differences are much greater．由此可知，该书可以让读者体验跨国文化，结合选项，故选B22．A 细节题．根据文章内容It's hard to read this book without wanting to leave forthe mountains to brainstorm bad haikus on the trail and cook canned macaroni and cheese over a crackling campfire．读者读完这本书就很难不想象着要前往书中描述的场景去感受一番，结合选项，故选A23．C 细节题．根据文章内容But The Old Patagonian Express，which is about a train journey Theroux made from Boston，USA to southern Argentina，is right up there at the top of my list．由此可知，Paul Theroux写的书 The Old Patagonian Express 是以他从美国到阿根廷去的火车旅行为基调的，结合选项，故选C24．D

Baltimore in Turner Station where Day worked at a steel mill．After giving birth to her fifth child，she was diagnosed with cervical cancer．She was treated at Johns Hopkins，the only hospital within twenty miles that treated black patients and had been established as a charity hospital．In an attempt to grow everlasting cells，Dr．George Gey took samples of all women who came to Hopkins with cervical cancer．After taking a biopsy （活检） of Henrietta's cervical cancer，researcher Dr．George Gey discovered that unlike any cells they had seen before，Henrietta's cells could not only reproduce，but thrive outside the body﹣﹣a breakthrough that would change modern medicine．Actually，her cells doubled in size every 24 hours and Dr．Gey shared these cells for free with any researcher interested．Later，Dr．Stanley Gartler found that Henrietta's cells were even capable of jumping out of the petri dish（培养皿） and taking other cell types．As a result，these cells，named HeLa（for Henrietta Lacks） were essential in the research into cancer，AIDS，the effects of radiation and poisonous substances，gene mapping，and countless other scientific pursuits．And they've been used in tens of thousands of research studies．Ms．Lacks died not too long after her diagnosis in 1951．She unknowingly held the key to unlocking medical advancements in her tumor cells．Now，decades afterHenrietta's death，her cells are still alive．For many years，her family knew nothing about the impact her cells had on medical science﹣she provided a crucial sample of cells that has furthered the knowledge of medical science and disease prevention． Now nearly 60years after her death，in May 2011，Morgan State University in Baltimore awarded her an honorary degree．25．What is the passage mainly about？ AA．A woman's contribution to medical progress．B．The contribution of Johns Hopkins．C．The original research of cancer．D．The death of a black patient．26．Which word can describe the cells of Henrietta Lacks？ C A．Radioactive．B．Poisonous．C．Active．D．Interesting．27．What does the underlined word"thrive"mean probably？ B A．Die．B．Grow．C．Break．D．Change．【考点】O1：人物故事类．【分析】本文主要讲的是一位名叫Henrietta Lacks 的女士因其独特的肿瘤细胞对于医药科学领域的贡献在去世60周年以后的2011年被摩根州立大学授予荣誉学位的故事．【解答】25﹣27．ACB25题答案：A 考查文章大意，本文主要讲的是一位名叫Henrietta Lacks 的女士因其独特的肿瘤细胞对于医药科学领域的贡献在去世60周年以后的2011年被摩根州立大学授予荣誉学位的故事，故本题答案为A选项．26题答案：C

It’s impossible to settle on just one. But The Old Patagonian Express, which is about a train journey Theroux made from Boston, USA to southern Argentina, is right up there at the top of my list. Theroux has a wicked sense of humor. He brings so much wisdom and experience to his travels.Walden by Henry David ThoreauIf he were alive today, Thoreau would probably frown if he heard someone refer to Walden as a travel book. But I regard it as a travel-writing masterpiece. “I went into the woods,”he writes, “because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived.”That’s the same spirit of discovery that defines so many great contemporary travel records.The Dharma Bums by Jack KerouacLike so many people, I fell in love with Kerouac’s novels in my late teens and early 20s. On the Road gets all the press, but I always love The Dharma Bums. Kerouac beautifully captures the romance of California trains, Berkeley, and backpacking in the Sierras. It’s hard to read this book without wanting to leave for the mountains to brainstorm bad haikus on the trail and cook canned macaroni and cheese over a crackling campfire.Confucius Lives Next Door by T. R. ReidThis is sort of A Year in Provence in Japan, only the cross-cultural differences are much greater. Reid and his family moved to Tokyo when he became the chief for The Washington Post, enabling him to uncover truths about the country. Among the highlights are his observations about Japanese schools, including Yodobashi No. 6Elementary School, where his daughters were greeted by the whole school staff.21．Which book enables readers to experience great cross-cultural differences? _______A．The Old Patagonian Express. B．Confucius Lives Next Door.C．On the Road. D．Walden.22．What will people feel after reading Jack Kerouac’s The Dharma Bums? _______A．A strong desire to follow.B．A love for novels.C．A wish to learn cooking.D．An excitement to write poems.23．Which writer based his book on a train journey from home to abroad? _______A．T. R. Reid. B．Henry David Thoreau. C．Paul Theroux. D．Jack Kerouac. 24．What features most modern travel books according to the author? _______A．Experience. B．Observation. C．Culture. D．Discovery.BHenrietta Lacks was born in 1920 in Virginia and raised on a tobacco farm. She married her first cousin, David Day and later settled near Baltimore in Turner Station where Day worked at a steel mill. After giving birth to her fifthhorse manure were produced and had to be swept up and disposed of.In 1898the first international urban-planning conference was held in New York. It was abandoned after three days, instead of the scheduled ten, because nobody could see any solution to the growing crisis by urban horses and their output.The problem did seem tough. The larger and richer that cities became, the more horses they needed. The more horses, the more manure. In 1894, a writer estimated that in 50 years every street in London would be buried under nine feet of manure. Moreover, all these horses had to be stabled, which used up ever-larger areas of increasingly valuable land. And as the number of horses grew, ever-more land had to be devoted to producing hay to feed them （rather than producing food for people）, and this had to be brought into cities and distributed-by horse-drawn vehicles. It seemed that urban civilization was doomed.Of course, urban civilization was not buried in manure. Because millions of horses were replaced by motor vehicles! This was possible because of cleverness of inventors and entrepreneurs such as Gottlieb Daimler and Henry Ford, and a system that gave them the freedom to put their ideas into practice. Even more important, however, was the existence of the price mechanism. When the price of horse-drawn transport rose steadily with the increasing cost of feeding and housing horses, strong incentives（动机）were created for people to find alternatives.32．How would you feel if you were walking on the New York street of 1900? _______A．Sick. B．Light-hearted. C．Excited. D．Satisfied. 33．What was the problem that New York faced one hundred years ago? _______A．Heavy traffic. B．Narrow streets. C．Little valuable land. D．Horse manure. 34．What was the probable target of the first international urban-planning conference in 1898? _______A．To feed more horses.B．To find a solution to horse manure.C．To reduce public buses.D．To produce motor vehicles.35．What was the most important factor in solving the urban civilization problem of New York? _______ A．Entrepreneurs’ freedom.B．People’s incentives.C．Price mechanism.D．Government’s appeal.第二节（共5小题;每小题2分,共10分）根据短文内容,从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项.Snow blind—it’s a frightening word. Thankfully, it’s a condition that is totally preventable.Snow blindness is a painful, temporary loss of vision due to overexposure to the sun’s UV rays. Essentially, snow blindness is caused by a sunburned eye.36 Though it is commonly called snow blindness, the condition can （and often does）occur in the absence of snow.The terms “snow blind”and “snow blindness”have become popular because snow is highly reflective of ultraviolet radiation. 37 Also, skiing, mountain climbing and snowboarding usually take place at relatively high altitudes, where the sun’s UV rays are stronger. Combined, these factors can double your risk of getting sunburned eyes, compared with being outdoors at lower altitudes in the summertime.38 Television journalist Anderson Cooper experienced snow-free snow blindness first-hand a few years ago when he spent a couple hours on a boat in Portugal without sunglasses and ended up “blind for 36hours,”according to his report of the incident.Not only can you become snow blind without snow—it can happen without sunlight, too! 39 For example, sun lamps can cause temporary “snow” blindness if proper eye protection is not used.40 To relieve pain or discomfort from snow blindness, stay indoors and wear sunglasses. Keep your eyes well-moistened with artificial tears. For additional relief, use over-the-counter pain relievers. Be sure to use only pain relievers you know you can take without worry of an allergic reaction. You also may find that placing a cool, dampened washcloth over your closed eyelids is comforting.A．You don’t need snow to become snow blind.B．It will likely affect those traveling in snowy conditions.C．To prevent snow blindness on the slopes, wear sunglasses.D．Sometimes it occurs from man-made sources of ultraviolet radiation.E．In fact, snow can reflect over 80percent of the UV rays that fall upon it.F．Snow blindness is scary, but usually it’s temporary, and there are ways to relieve the discomfort.G．.But water and white sand also are highly reflective of the sun’s UV rays, thus increasing the risk.第三部分:英语知识运用（共两节,满分45分）第一节完形填空（共20小题;每小题1.5分,满分30分）阅读下面短文,从短文后各题所给的四个选项（A、B、C和D）中选出可以填入空白处的最佳选项,并在答题卡上将该项涂黑.There was a businessman who was deep in debt and could see no way out.He sat on the park bench, head in hands, 41 if anything could save his company from bankruptcy（破产）.Suddenly an old man appeared before him. “I can see that something is 42 you,” he said.After listening to the businessman’s troubles, the old man said, “I believe I can help you.”He asked the man his name, wrote out a 43 , and pushed it into his hand saying, “Take this money.

It was his 60 self-confidence that gave him the power to achieve anything he went after.41．A．wondering B．suspecting C．estimating D．hesitating 42．A．attacking B．disturbing C．interrupting D．amusing 43．A．number B．note C．letter D．check 44．A．calmly B．quietly C．quickly D．proudly 45．A．signed B．handed C．Drawn D．deposited 46．A．lose B．remove C．face D．ignore 47．A．instead B．therefore C．rather D．meanwhile 48．A．weakness B．belief C．urge D．strength 49．A．creativity B．permission C．optimism D．curiosity 50．A．hospital B．Company C．street D．park 51．A．advanced B．appointed C．announced D．delayed 52．A．hand back B．give out C．put out D．turn over 53．A．policeman B．banker C．nurse D．guard 54．A．Beat B．Cheated C．pushed D．caught 55．A．never B．seldom C．always D．occasionally 56．A．on B．in C．by D．at 57．A．exhausted B．astonished C．Disappointed D．excited 58．A．convinced B．informed C．reminded D．warned 59．A．created B．imagined C．Discovered D．donated 60．A．long-lost B．non-existent C．ever-lasting D．newly-found第二节语法填空（共10小题;每小题1.5分,满分15分）阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式.I made my first visit to China in 2008 and last year, I 61 （be）lucky enough to take part in an event called “Shanxi in the eyes of foreigners”.Shanxi is Chinese for “west of the mountains”, meaning the Taihang Mountains.

ANathan，a freshman student at San Marino High School in California，US，doesn’t like doing housework any more than anybody else．But he said doing it made him wonder why hot water worked better than cold water when washing up after dinner，and what made soap a good cleaner．The experiments he designed to figure out these things earned him the top prize at the 2016 Broadcom MASTERS．MASTERS stands for Math，Applied Science，Technology and Engineering for Rising Stars．Every year，the event brings together 30 middle school students from around the country to share their science projects．“At first，I thought that my ideas were naive，”the teenager told Student Science．“But when I was presented with this special award，it proved that young inventors can actually deal with real-world problems．”Inspired by reports of the Deepwater Horizon oil spill in the Gulf of Mexico，he connected washing dishes to cleaning oil spills．“I decided that I wanted to find a method for cleaning that’s both efficient and environmentally friendly，”Nathan told Student Science．So he created his own setup for measuring surface tension—a scientific term that refers to the tension of a layer of liquid．He ended up learning why soap and hot water are better for cleaning，and a way to remove oil from water.“Science and math help you understand the world around you．You can learn it from books and teachers，but you can also discover it yourself by doing science projects．”He even plans to sell his setup to schools，so other teens can do his experiment and learn his theory．When asked his secret to success，he said to keep a science fair project simple at first．“Break down the problem into smaller，manageable steps，so in that way，you will be able to know what you doing and build on your knowledge gradually．”21．What do we know about Nathan?A．He enjoys doing housework．B．He wants to clean up oil spills．C．He figured out how cleaning worked．D．He won many prizes for his fancy ideas．22．What can best describe Nathan?A．Generous and wealthy．B．Curious and creative．C．Lazy but talented．D．Polite but shy．23．What is Nathan’s secret to success?A．Doing things step by step．B．Doing science projects alone．C．Working hard at math problems．D．Learning about the world from books．BThe modern pizza was originally invented in Naples，Italy，but the word pizza is Greek in origin，derived from the Greek word pēktos meaning solid or clotted．The ancient Greeks covered their bread with oils，herbs and cheese．The first major innovation that led to flat bread pizza was the use of tomato as a topping．It was common for the poor of the area around Naples to add tomatoes to their yeast-based flat bread，and so the pizza began．While it is difficult to say for sure who invented the pizza，it is however believed that modern pizza was first made by baker Raffaele Esposito of Naples．In fact，a popular urban legend holds that the archetypal(原型的)pizza，Pizza Margherita，was invented in 1889，when the Royal Palace of Capodimonte asked the Neapolitan pizzaiolo Raffaele Esposito to create a pizza in honor of the visiting Queen Margherita．Of the three different pizzas he created，the Queen strongly preferred a pie wrapped in the colors of the Italian flag：red (tomato)，green(basil)，and white(mozzarella)．Supposedly，this kind of pizza was then named after the Queen as Pizza Margherita．Later，the dish has become popular in many parts of the world：■The first pizzeria，Antica Pizzeria Port'Alba，was opened in 1830 in Naples．■In North America，the first pizzeria was opened in 1905 by Gennaro Lombardi at 53 Spring Street in New York City．■The first Pizza Hut，the chain of pizza restaurants appeared in the United States during the 1930s．■Nowadays，many varieties of pizza exist worldwide，along with several dish variants based upon pizza．24．What’s mainly talked about in the text?A．Ways of making Pizza．B．The history of Pizza．C．Varieties of Pizza．D．Stories about Pizza．25．What can replace the underlined word“derived”in Paragraph 1?A．Separated．B．Adapted．C．Originated．D．Transformed．26．How was pizza first started?A．Ancient Greeks covered their bread with oils，herbs and cheese．B．People in Naples added tomatoes to their bread as a topping．C．Raffaele Esposito wrapped a pie in the colors of the Indian flag．D．Queen Margherita awarded her name to pizza in the Royal Palace．27．What can be learned from the text?A．Pizza remains popular around the world．B．The first Pizza Hut was opened in Naples．C．The taste of pizza stays the same over time．D．Gennaro Lombardi was the first to make pizza．CThe Amazon basin region is home to about 2．5 million insect species，tens of thousands of plants，and some 2，000 birds and mammals．To date，at least 40，000 plant species，3，000 fish，1，294 birds，427 mammals，428 amphibians，and 378 reptiles have been scientifically classified in the region．One in five of all the birds in the world live in the rain forests of the Amazon.The warm wet forests have been in existence for 55 million years，and thrived even during glacial periods，allowing for the evolution of an unbelievable diversity of species，Radiocarbon dating(放射性碳年代测定)has revealed trees of 10 centimeter diameter to be more than 300 years old，and some trees over 1，000 years old，indicating that untouched forests can experience unbelievable longevity．The first human inhabitants are thought to have settled in the Amazon region about 11，200 years ago．European explorers arrived in the 16th century，bringing diseases which traveled faster than the explorers themselves，killing perhaps as many as 90％of the indigenous inhabitants(土著居民)．By the late 17th century the Amazon basin was controlled by Portuguese and Spanish explorers．The Amazon rain forest has been described as the lungs of our planet because of its important role in recycling carbon dioxide into oxygen. But due to deforestation(采伐森林)，cover than 5 % of the Earth land surface，and experts believe that this rain to rests now cover less than the Earth’s land surface，and experts believe that this is a big contributor to global climate change．Severe deforestation began in the 20th century，with 587，000 square kilometers lost up to the year 2000．Most deforested land is used for grassland to raise farm animals and agriculture．The addition of transport routes has led to increased settlement and deforestation，and at the present rate，scientists estimate that the Amazon rain forest will be reduced by 40％in two decades．28．Why are the figures mentioned in Paragraph 1 ?A．To prove the forest untouched．B．To classify species scientifically．C．To show the diversity of species．D．To attract more attention to Amazon.29．Why did most indigenous inhabitants in the Amazon region die?A．European explorers brought diseases there．B．Portuguese explorers treated them badly．C．A lot of trees were cut down and burned．D．They got killed by Spanish explorers．30．What can be inferred about the Amazon rain forest?A．It has the largest number of species．B．It covers over 5％of South America．C．It is becoming larger in area．D．It is being endangered now．31．What may be included in the following paragraph?A．Examples of destroying forests．B．Measures to protect rain forests．C．New settlements in Amazon．D．Ways to stop global warming．DPassword fatigue(疲劳)is the feeling experienced by many people who are required to remember an increasing number of passwords as part of their daily routine，such as to log on to a computer at work，undo a bicycle lock or conduct banking from an ATM.The increasing importance of information technology and the Internet in employment，finance，recreation and other aspects of people’s lives，and the following introduction of secure deal technology，has led to people accumulating a sudden increase in accounts and passwords．According to a survey of British online-security consultant NTA Monitor，the typical regular computer user has 21 accounts that require a password．Other things causing password fatigue are：demands that a user create a new password that uses particular pattern of letters，numbers and special characters；demands that the user type the new password twice；blind typing，both when responding to a password immediately and when setting a new password．Aside from contributing to stress，password fatigue may encourage people to adopt habits that reduce the security of their protected information．For example，an account holder might use the same password for several different accounts，deliberately choose easy-to-remember passwords that are more likely to be solved，or rely on written records of their passwords．Password fatigue will typically affect users，but can also affect technical departments who manage user accounts as they are constantly resetting passwords．This situation ends up lowering confidence and enthusiasm in both cases．Some companies are well organized in this respect，and have employed alternative methods or adopted technologies so that a user’s certificates are entered automatically，but others may not focus on ease of use or even worsen the situation by constantly carrying out new applications with their own certification system．32．What is the main idea of Paragraphs 2?A．Reasons for password fatigue．B．Definition of password fatigue．C．Roles of the Internet in daily life．D．A survey on regular computer users．33．What may password fatigue cause people to do?A．To choose complex passwords．B．To improve their memory．C．To use the same passwords.D．To learn passwords by heart．34．What can we infer about password fatigue? A．It may create new accounts．B．It can be finally solved in future．C．It can encourage account holders．D．It will continue to exist for ever．35．Which of the following shows the structure of the text?(P=Paragraph)第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
