Note that there is one word more than you need.On a(an)(31)_______ bullet train,a virus suddenly spreads throughout like wildfire. Will you lend a helping hand to those in need, or focus all your energy on self-preservation?Train to Busan, a South Korean zombie film which raises this question, has recently set Chinese social mediaaflutter.To fulfill his young daughter’s birthday wish, divorced hedge fund manager Seok-wu (Gong Yoo) takes the girl on a train from Seoul to Busan to visit hermother.Early in the journey, ascruffy-looking young woman staggers onto the train at the last second, herself(32)_______ infected by something.It doesn’t take a hardcore fan of the genre to predict what happens next–the dead-looking girl takes a bite out of a passing attendant, then all hell breaks(33)________. Both would-be saviors and cowardly egocentrics(以自我为中心)are among those who are able to fight their way to survive.However, unlike the traditional powerful and obliging heroes of Western zombie stories, Seok-wu, as the lead protagonist, never intends to save the day during the most part.Setting his character’s tone, the self-(34)________ man locks the door for his own safety when a pregnant woman fleeing from zombies tries to get in. He forbids his daughter to offer her seat to an elderly woman, telling her that only ones own well-being(35)_________in extreme conditions. He also uses his contacts to try(36)_________ a way out for him and his young daughter, not considering his hundreds of fellow passengers.Even when he(37)_________ up with a dauntless(无所畏惧的) bruiser and a high school baseball player to fight the zombie hoard, the viewer can guess that his only motivation is the survival of him and his daughter.Compared with the familiar gore-fests of TV series like The Walking Dead (2010-), Train to Busan actually provides a(38)________bloody setting, instead focusing on the complexities of human behavior, rather than the senseless shedding of limbs.The zombie genre has been done to death –no pun intended –but Train to Busan largely(39)________ its success to its vivid character portrayal.For example, the central character is a workaholic father who doesn’t pay enough attention to his daughter but ends up putting his life at stake for her. We also see a selfish, middle-aged man who later reveals that his only mission is to simply reunite with his mother. Love and relationships seem to be a central theme, with a young couple proving their loyalty to one another as well as two elderly sisters who serve to represent family(40)________.答案:31.BC 32.CD 33.D 34.A 35.AB 36.BD 37.ABC 38.C 39.AD 40.B 错题分析:31,packed在这里是个形容词,表示异常的,拥挤的。

Fill in each blank with the word or phrase that best fits the context.Probably the number one complaint about reading Shakespeare is that it doesn't always read like "normal" English. It's a natural and legitimate___41___. Shakespeare wrote for an audience over 400 years ago. Think about how word meanings and expressions change over a relatively short time; four centuries bring with them a lot of ___42___ .The Elizabethan era was a particularly volatile growth spurt in the English language. The Renaissance and England's emerging status as a sea power ___43___ the language to an ever-increasing range of cultures and languages. At the same time, there was no real standardization in English. Formal dictionaries and grammar textbooks ___44___ did not exist, and "proper" education focused much more on classical Latin than on colloquial English. Despite this neglect ---- or perhaps because of it ----English by the reign of Elizabeth had a certain flexibility to it, of which Shakespeare ___45___.So how can a reader today __46____ that gap between then and now? There are two critical areas to ___47___ : word usage, grammar. Once you understand these fundamental concepts, Shakespeare becomes a lot more ___48___.First and foremost, there have been numerous vocabulary changes in English since Shakespeare was writing. While many words are still recognizable today, others have shifted in their meaning or dropped altogether from usage. ___49___, when was the last time you heard anyone use words such as bodkin (a piercing tool), contumely (verbal abuse), or fardel (a bundle)? There are also conventions such as the informal thou versus the formal you; think of this the same way that tú and usted are used in Spanish, or du and sie in German. Often the context in which a word is used will help you determine its meaning. A good ___50___ with detailed footnotes will help you, as well as a good dictionary. The main thing is to be aware that even a familiar word from today may be used with a different meaning in Shakespeare's works.Grammar is where the ___51___ of Shakespeare's English is often most apparent. Parts of speech are frequently___52___, such as nouns or adjectives becoming verbs. Verbs and subjects don't always ___53___. Words are often omitted in phrases. Word endings such as -ly are inconsistently applied. Shakespeare uses double negatives in spots and phrases such as "most unkindest" with regularity. Even sentence construction can be ___54___, with inversions of the basic subject-verb-object order. ___55___ we would say, "John caught the ball," Shakespeare might render the same statement with the same meaning as "John the ball caught," or "The ball John caught." As a result, it's important to recognize which part of speech a given word actually represents in a given line.41. A. oppression B. accusation C. direction D. appreciation42.

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 you have just read.AComputers have been taught to play not only checkers, but also championship chess, which is a fairly accurate yardstick for measuring the computer’s progress in the ability to learn from experience.Because the game requires logical reasoning, chess would seem to be perfectly suited to the computer. All a programmer has to do is give the computer a program evaluating the consequences of every possible response to every possible move, and the computer will win every time. In theory this is a sensible approach; in practice it is impossible. Today, a powerful computer can analyze 40 000 moves a second. That is an impressive speed. But there are an astronomical number of possible moves in chess ---- literally trillions. Even if such a program were written (and in theory it could be given enough people and enough time), there is no computer capable of holding that much data.Therefore, if the computer is to compete at championship levels, it must be programmed to function with less than complete data. It must be able to learn from experience, to modify its own program, to deal with a relatively unstructured situation ---- i n a word, to ―think‖ for itself. In fact, this can be done. Chess-playing computers have yet to defeat world champion chess players, but several have beaten human players of only slightly lower ranks. The computers have had programs to carry them through the early, mechanical stages of their chess games. But they have gone on from there to reason and learn, and sometimes to win the game.There are other proofs that computers can be programmed to learn, but this example is sufficient to demonstrate the point. Granted, winning a game of chess is not an earthshaking eventeven when a computer does it. But there are many serious human problems which can be fruitfully approached as games. The Defense Department uses computers to play war games and work out strategies for dealing with international tensions. Other problems ----international and interpersonal relations, ecology and economics, and the ever-increasing threat of world famine ---- can perhaps be solved by the joint efforts of human beings and truly intelligent computers.56. The purpose of creating chess-playing computers is __________ .A. to win the world chess championB. to pave the way for further intelligent computersC. to work out strategies for international warsD. to find an accurate yardstick for measuring computer progress57. Today, a chess-playing computer can be programmed to __________ .A. give trillions of responses in a second to each possible move and win the gameB. function with complete data and beat the best playersC. learn from chess-playing in the early stage and go on to win the gameD. evaluate every possible move but may fail to give the right response each time58. For a computer to ―think‖, it is necessary to __________ .A. mange to process as much data as possible in a secondB. program it so that it can learn from its experiencesC. prepare it for chess-playing firstD. enable it to deal with unstructured situations59. The author’s attitude towards the Defense Department is __________ .A. criticalB. unconcernedC. positiveD. negativeBThe following are four resumes (简历) of four persons.Hannah Oyler21 Balsom St Ventura, CA 94120 (613)555–7236Objective To obtain a position as a photographer for a major metropolitan (大都市的) newspaper.Notable Achievements Time Magazine, Top Photos of the Year 1999 for California Wildfire Banaker; Excellence in Photography Fellowship, 1995.ExperienceVentura County Times Staff photographer, 1996—Present,Regular coverage included: Sports, Lifestyle, & Metro.

According to the passage, what do the four persons have in common?A. They have been in their present jobs for at least 20 years.B. Each is living in the same state where his university lies.C. They took their present jobs soon after they left university.D. They want to obtain a position that is related to their majors.CThe first two stages in the development of civilized man were probably the invention of weapons and the discovery of fire, although nobody knows exactly when he acquired the use of the latter.The origin of language is also difficult to understand. No doubt it began very gradually. Animals have a few cries that serve as signals, but even the highest apes have not been found able to pronounce words, even with the most intensive professional instruction. The superior brain of man is apparently a necessity for the mastering of speech. When man became intelligent enough, we must suppose that he gradually increased the number of cries for different purposes. It was a great day when he discovered that speech could be used for describing and telling stories. There are those who think in this respect picture language appeared before oral language. A man could draw a picture on the wall of his cave to show in which direction he had gone, or what prey he hoped to catch. Probably picture language and oral language developed side by side. I prefer to think that language has been the most important single factor in the development of man.Two important stages came not so long before the dawn of written history. The first was the domestication of animals. The second was agriculture. Agriculture was a step in human progress to which there was nothing comparable until our own machine age. Agriculture made possible a huge increase in the number of the human species in the regions where it could be successfully practiced. These were, at first, only those in which nature fertilized the soil after each harvest. Agriculture met with violent resistance from the pastoral nomads (游牧民族), but the agricultural way of life was accepted in the end because of the physical comforts it provided.Another fundamental technical advance was writing, which, like spoken language, developed out of pictures, but as soon as it had reached a certain stage, it was possible to keep records and transmit information to people who were not present when the information was given.These inventions and discoveries ---- fire, speech, weapons, domestic animals, agriculture, and writing ----made the existence of civilized communities possible. From about 3000 B. C. until the beginning of the Industrial Revolution less than two hundred years ago there was no technical advance comparable to these. During this long period man had time to become accustomed to his technique, and to develop the beliefs and political organizations appropriate to it. There was, of course, a big extension in the area of civilized life. At first it had been confined to the Nile, the Euphrates, the Tigris and the Indus, but at the end of the period inquestion it covered much the greater part of the inhabitable globe. I do not mean to suggest that there was no technical progress during this long time; there was progress ---- there were even two inventions of very great importance, namely gunpowder and the compass ---- but neither of these can be compared in their power to such things as speech and writing and agriculture.63. According to the above passage, we can conclude that ___________.A. the use of fire and the domestication of animals made agriculture possibleB. progress was probably very slow when language first came into beingC. gunpowder and the compass are as important as speech in historyD. communication is the most important factor for human development64. From the article we can learn that agriculture ___________.A. was accepted as soon as it appearedB. is as great a step forward as our machine ageC. helped improve the techniques of domesticationD. at first helped make the land more suitable for crops65. Which is the right order of the appearance of the following things(a to e)?a. agricultureb. weaponsc. domestication of animalsd. written languagee. political organizationsA. c, a, d, b, eB. e, b, c, d, aC. b, a, c, d, eD. b, c, a, d, e66. Which of the following is the best title of the article?A. The Development of CivilizationB. Speech and CivilizationC. The Origin of LanguageD. The First Two StagesSection C (8%)Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.Have you got an addictive nature? Are you unable to stop yourself joining in with the latest obsession for collecting or doing something? This probably describes most of us because it's only human nature to not want to miss out on something that everyone else is talking about.Most fads arrive suddenly and enthusiasm for them spreads quickly. They become a talking point on social media; we read about them, give them a try and, before we know it, we are hooked. In the past, (67.)___________. Maybe you were the proud owner of a Rubik's cube, which became the best-selling toy of all time – around 350 million have been sold so far.Now, technology is driving the latest crazes. In some parts of the world, flavour of the month is Pokémon Go ---- a game that uses augmented reality, where little virtual monsters pop up onto your phone and you have tocatch them. And games such as Angry Birds and Minecraft are other crazes, available on smartphones and tablets that have been hard to put down.Our keenness to participate in crazes has been analyzed by experts. One of them, Dr Ben Michaelis, a clinical psychologist, explains that (68.)_____________and this "hooks into an ancient evolutionary fear of being left behind or abandoned by our tribes"; we have to join in or lose out.Although becoming addicted to a computer game might not seem like a 'benefit', (69.)_____________. It allows you to learn new skills and gives you something to talk about at parties!But fashions come and go and most fads are just a flash in the pan so if one of them is not your cup of tea, don't worry: (70.)_______________. Look at the addiction to the unsophisticated loom bands – those little rubber bands you could make jewelry and other things out of. For a brief period they were the must-have item for any schoolchild, now they're the bargain bucket item in a discount shop or worse still, trash filling up our landfill sites! What crazes have you been addicted to?第Ⅱ卷(共50分)I. Translation (15% = 3+3+4+5)Directions: Translate the following sentences into English, using the words given in the brackets.1. 我觉得食品安全问题在于法规和道德的缺失。

He picked up the sushi, nodded at the other drivers, and got back on his bike. Hungry people were waiting.Section BDirection:Complete the following passage by using the words in the box. Each word can be used once. Note that there is one word more than you need.On a(an)(31)_______ bullet train, a virus suddenly spreads throughout like wildfire. Will you lend a helping hand to those in need, or focus all your energy on self-preservation?Train to Busan, a South Korean zombie film which raises this question, has recently set Chinese social media aflutter. To fulfill his young daughter’s birthday wish, divorced hedge fund manager Seok-wu (Gong Yoo) takes the girl on a train from Seoul to Busan to visit her mother. Early in the journey, a scruffy-looking young woman staggers onto the train at the last second, herself(32)_______ infected by something.It doesn’t take a hardcore fan of the ge nre to predict what happens next–the dead-looking girl takes a bite out of a passing attendant, then all hell breaks(33)________. Both would-be saviors and cowardly egocentrics(以自我为中心)are among those who are able to fight their way to survive.However, unlike the traditional powerful and obliging heroes of Western zombie stories, Seok-wu, as the lead protagonist, never intends to save the day during the most part.Setting his character’s tone, the self-(34)________ man locks the door for his own safety when a pregnant woman fleeing from zombies tries to get in. He forbids his daughter to offer her seat to an elderly woman, telling her that only ones ownwell-being(35)_________ matters in extreme conditions. He also uses his contacts to try(36)_________ a way out for him and his young daughter, not considering his hundreds of fellow passengers. Even when he(37)_________ up with a dauntless(无所畏惧的) bruiser and a high school baseball player to fight the zombie hoard, the viewer can guess that his only motivation is the survival of him and his daughter.Compared with the familiar gore-fests of TV series like The Walking Dead (2010-), Train to Busan actually provides a(38)________bloody setting, instead focusing on the complexities of human behavior, rather than the senseless shedding of limbs. The zombie genre has been done to death –no pun intended –but Train to Busan largely(39)________ its success to its vivid character portrayal. For example, the central character is a workaholic father who doesn’t pay enough attention to his daughter but ends up putting his life at stake for her. We also see a selfish, middle-aged man who later reveals that his only mission is to simply reunite with his mother. Love and relationships seem to be a central theme, with a young couple proving their loyalty to one another as well as two elderly sisters who serve to represent family(40)________.III.

Future B. Youth C. Death D. ImmortalitySection B(A)He lived a tragically short life, but one that was full of incident. The English writer Percy Bysshe Shelley chose the wrong day to go on a sea trip: He drowned in the Gulf of Spezia near Italy, aged 29, in 1822.Born with a silver spoon in his mouth, Shelley went to the University of Oxford but did not complete his studies. He was thrown out for writing a book called the Necessity of Atheism at a time when you couldn’t talk easily about not believing in God.This radical view of the world led him to take the side of the underdogs of society. In Manchester in 1819 there was a demonstration of between 60,000 and 8000 working people. They wanted to be able to vote for members of parliament. They were cut down by the police, and many were killed or injured. To express his support for there cause. Shelley wrote a poem called The Masque of Anarchy. It closes by asking people to rise in “unvanquishable number” and reminds readers :“You are many-they are few”This calls for people to rise up-the spirit of revolution-is present in many of his poems. Perhaps his greatest poem is Ode to the West Wind. Although it seems simply to be about nature and the seasons, these actually show social struggles. It was written at a time when those struggles seemed to have been defeated. Everything seemed to be winter as far as social justice went. Nevertheless, Shelley ends the piece with an inspiring question: “If Winter comes, can Spring be far behind”Of the many memorable question :“If winter comes, can Spring be far behind?”Of the many memorable lines Shelley wrote, these may be the most meaningful. They also perfectly expects the idealism and political commitment in his poetry.56.A. Died of an illness at a young ageB. Didn’t believe in the existence of GodC. Was a famous Romantic poet in the 18th centuryD. Called for justice because he was born into a poor family57.A. He couldn’t afford the tuition feesB. He wanted to devoted himself to writingC.

Hes was optimistic about revolutionB. He was worried about social strugglesC. He believed that there was no absolute social justiceD. He was more interested in nature that he was in politics(B)We have been all there -when liming up at the supermarket checkout counter, the lines next to us always seem to be moving faster than the one we are standing in. Now The New York Times has put together the research of multiple scientists to give you some insights into the math and psychology of queuing. It has also offered tips on licking the fastest line no matter you’re lining up in a supermarket, a bank or anywhere else.Pick someone with a full cartUS mathematician Dan Meyer believes that a cart full of items doesn’t tell the whole story. “Every person requires a fixed amount of time is an average of 41 seconds per person. On the other hand, the time that each item takes to be rung up is only three seconds. This means if only one person ahead of you, with 50 items in the cart, the waiting time is 191 seconds. You do the math”Study the customersH ow many people are ahead of you is one thing, and who they are is another. Forexample, if they are old people-and this is not ageist-they tend to move slower and delay the checkout process . The items their carts are also important. For example, four bottles of the milk will definitely go faster than four completely different items.Choose a “serpentine line”In some place, there may just be one line leading to several checkout counts. The person at the head of line goes to next available counter. This is known as a “serpentine line”. You should always choose a serpentine line because even i f one of the cashiers is slow, it won’t hold up an entire lion.Go leftAccording to Robert Samuel, a US science writer, around 90 percent of people are right-handed, which means they tend to naturally go to the right. So heading to the opposite direction-left-will give you a better chance of finding a faster line.60.What is the purpose of the passage?A. To list the potential dangers of choosing a wrong queueB. To tell tell readers which supermarket can save the most timeC. To instruct the readers how to avoid picking the wrong queueD. To provide some tips on how to kill time when one is in the line61.A. A checkout assistant will save time if he rings up goods fsterB. Finishing a cart full of items can be limited to only 41 1secondsC. Trolleys with full loads doesn’t mean waiting for a longer time.D. Maths fails to account for the theory behind one’s waiting time62.relatively slower than the others.A. The line you choose are among the ones on the rightB. The checkout assistant have to go through the routineC. You are waiting behind a group of teenage customersD. You have chosen a serpentine line over a straight one(C)It seems that smoking isn't the popular pastime it used to be in the West, For example,figures published recently by the BBC say that the amount of smokers in England is dropping drastically each year and is now its lowest ever, with just 16.9 percent of adults still participating in the habitBut what is it that’s enticing British people to throw away the cigs and get motivated to live a smoke-free style? Each year, October is a time to quit in the UK. Beginning in 2012,“Stoptober”is an annual gov ernment-run scheme that encourages Brits to say goodbye to cigarettes. Throughout the month, a series of TV and radio ads, alongside a smart phone app and social media campaign, offer help and inspiration to those considering going smoke-free.Among the people encouraged by this year's campaign was Samantha Griffiths, 31, a criminal investigation student from Preston, England. HI stopped smoking this year after 13 years -1 used to smoke almost a whole pack a day. I was inspired by Stoptober but decided to quit early, although Tm helping a friend who wants to quit this month she says.Earlier this year, UK authorities introduced several new restrictions on tobacco in the hope of getting people to quit. The changes included a ban on packs of 10 cigarettes - sold alongside regular packs (20 cigs) as they were cheaper - as well as the requirement of a uniform design on every manufacturer's packaging."Plain packaging” rules mean that every brand must now look the same - an olive green-colored pack with a shocking health warning image on each side. The brand name is now simply plain black lettering, with logos completely banned. The green color was chosen following research commissioned ($1^) by the Australian government (which introduced plain packaging in 2012) that tasked 1,000 smokers to choose a shade that would put them off their habit. Australia and the UK also have some of the highest tobacco taxes in the world, with a pack of Marlboro costing AS26 (133 yuan) in Australia. The same product can be had for as little as 20 yuan in China.“I was spending almost 250 (2,172 yuan) a month on cigarettes before 1 quit” says Griffiths “I am saving the money I would have spent to take my young daughter to Disneyland Pins next year.” So if you’re a smoker, why not join the Brits in trying to quit this month? You may not save enough to get toPairs, but fortunately China has a Disneyland of its own.63.Which of the following statement about stoptober is false?A.It is an official organization administered by the UK authorities.B.It contributes to the decrease in the number of smokers in the UK.C.It encourage people to stop smoking through a variety of channels.D.It inspired Samantha Griffiths to give up smoking from his October.64.Which of the following measures have the UK authorities adopted to control the amount of smokers?A.Those who quit smoking were granted a free trip to Paris Disneyland.B.A tax as heavy as that in Australia was imposed on a tobacco products.C.The use of green color is totally forbidden in the packing of cigarettes.D.Regular-sized cigarette were not permitted to be sold throughout the UK.65.According to the “plain packing” rules conducted in the UK ,what’s not printed on its cigarette packing?A.warning imageB.brand nameC.brand logoD.price tag66.Which of the following can best explain the last sentence “fortunately China hasa Disneyland of its own.”A.Patriotic China citizens will visit their own Disneyland rather than go abroad.B.In China, the expense spared from quitting smoking can ill afford a trip to Pairs.C.The strict no-smoking policy is gladly being implemented in China’s Disneyland.D.Tourists are entitled to purchasing less expensive cigarettes in China’s Disneyland.A generation ago in the US, if you heard a friend talking about having a gig, chances were that yourfriend was a musician. (67)___________________Self-employment, contract or freelance work, temporary jobs - just about anything that isn't full-time - can be described as a gig.The rise of the "gig economy" came along with the evolution of on-demand or as-needed hiring. Digital ordering, stock management, sales, andexpense programs have made large teams of full-time staff a thing of past with some companies taking on temporary workers as and when they need them.(68)_____________________For a while, the gig trend was seen as a temporary response to the Great Recession. Victims of downsizing took on as-needed jobs or tried to make a go of entrepreneurship because that's all that was available.(69)___________________.However, this did not happen on the scale they hoped. This shift means that driving for ride-sharing services like Uber or Lyft has become one of the most common new jobs in the US. Surveys find that many gig economy workers are happy with their new roles with the hourly pay may be better than what they earned as permanent employees. They may enjoy work-hour flexibility that’s perfect for their family or education needs. And they may even find they good at being their own boss.They said,however,Self-employment isn't for everyone. (70)_______ they're not self-starters or can't identify gig opportunities and follow through. Gigs are also not likely to provide traditional benefits such as subsidized healthcare insurance,and aren’t likely to come with retirement plans,although this m ay not be an issue for those with a well-developed financial discipline.Yes,the inconsistency of gigs can be scary.But,really,who doesn’t like an adventure?Summary writingYou are what you eat and fats are a main food for Asia’s fast-food generation. Dr. Chwang, director of the Department of Food Nutrition, says children are consuming more meat and soft drinks. That is a thorough departure from the traditional diet of vegetables and rice and little meat. “They like big pieces of fried meat with a soft drink. So although they may eat the same volume of food, their calorie intake (卡路里摄入量)has increased. Now about 40 to 45 percent of their calories come from fat,” says Chwang.Although on the whole Asians tend towards thinness, culture —namely Asians’ hospitality (好客)—is a reason for the fatness of today’s generation, according to Chwang. “Asian people love food,” she says. “Eating and drinking are important social and family functions. “In the past, however, big meals were only hosted on special occasions as people were more careful with money. In today’s climate of wealth and remarkable consumption, 10-course meals are no longer reserved for significant occasions.Needless to say ,the children are being spoiled by their parents is another cause of chil dren’s overweight. More than anyone else, children are on the receiving end of their parents’ improved circumstances. “In the past , people had four or more children —now, they have one or two, so they tend to spoil them ,” says Chwang. “The easiest way is to give them ‘quality food’. Parents think feeding them well is showing their love. They feel bad when their children look thin.”When describing the physical condition of most overweight Asian children, Chwang says: “There is a clear relationship bet ween fatness and indoor play. Children get fat because they don’t move, and eventually, they don’t want to move because they’re fat.Thanks to technology, a growing army of children prefer video games to old outdoor sports. “What do children do when watchi ng TV or sitting in front of the computer playing video games? They eat chocolate and drink Coke,” says Chwang.Translation1.用不了多久,印度的人口将达到14亿并赶超中国。

Reading Comprehension (45%)Section A (15%)Directions: For each blank in the following passage there are four words or phrases marked A, B,C and D. Fill in each blank with the word or phrase that best fits the context.Probably the number one complaint about reading Shakespeare is that it doesn't always read like "normal" English. It's a natural and legitimate___41___. Shakespeare wrote for an audience over 400 years ago. Think about how word meanings and expressions change over a relatively short time; four centuries bring with them a lot of ___42___ .The Elizabethan era was a particularly volatile growth spurt in the English language. The Renaissance and England's emerging status as a sea power ___43___ the language to an ever-increasing range of cultures and languages. At the same time, there was no real standardization in English. Formal dictionaries and grammar textbooks ___44___ did not exist, and "proper" education focused much more on classical Latin than on colloquial English. Despite this neglect ---- or perhaps because of it ----English by the reign of Elizabeth had a certain flexibility to it, of which Shakespeare ___45___.So how can a reader today __46____ that gap between then and now? There are two critical areas to ___47___ : word usage, grammar. Once you understand these fundamental concepts, Shakespeare becomes a lot more ___48___.First and foremost, there have been numerous vocabulary changes in English since Shakespeare was writing. While many words are still recognizable today, others have shifted in their meaning or dropped altogether from usage. ___49___, when was the last time you heard anyone use words such as bodkin (a piercing tool), contumely (verbal abuse), or fardel (a bundle)? There are also conventions such as the informal thou versus the formal you; think of this the same way that tú and usted are used in Spanish, or du and sie in German. Often the context in which a word is used will help you determine its meaning. A good ___50___ with detailed footnotes will help you, as well as a good dictionary. The main thing is to be aware that even a familiar word from today may be used with a different meaning in Shakespeare's works.Grammar is where the ___51___ of Shakespeare's English is often most apparent. Parts of speech are frequently___52___, such as nouns or adjectives becoming verbs. Verbs and subjects don't always ___53___. Words are often omitted in phrases. Word endings such as -ly are inconsistently applied. Shakespeare uses double negatives in spots and phrases such as "most unkindest" with regularity. Even sentence construction can be ___54___, with inversions of the basic subject-verb-object order. ___55___ we would say, "John caught the ball," Shakespeare might render the same statement with the same meaning as "John the ball caught," or "The ball John caught." As a result, it's important to recognize which part of speech a given word actually represents in a given line.41. A. oppression B. accusation C. direction D. appreciation42. A. specifics B. alterations C. improvements D. incidents43. A. exposed B. led C. contacted D. linked44. A. roughly B. arguably C. simply D. essentially45.

SinceSection B (22%)Directions: Read the following three passages. 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 you have just read.AComputers have been taught to play not only checkers, but also championship chess, which is a fairly accurate yardstick for measuring the computer’s progress in the ability to learn from experience.Because the game requires logical reasoning, chess would seem to be perfectly suited to the computer. All a programmer has to do is give the computer a program evaluating the consequences of every possible response to every possible move, and the computer will win every time. In theory this is a sensible approach; in practice it is impossible. Today, a powerful computer can analyze 40 000 moves a second. That is an impressive speed. But there are an astronomical number of possible moves in chess ---- literally trillions. Even if such a program were written (and in theory it could be given enough people and enough time), there is no computer capable of holding that much data.Therefore, if the computer is to compete at championship levels, it must be programmed to function with less than complete data. It must be able to learn from experience, to modify its own program, to deal with a relatively unstructured situation ---- i n a word, to ―think‖ for itself. In fact, this can be done. Chess-playing computers have yet to defeat world champion chess players, but several have beaten human players of only slightly lower ranks. The computers have had programs to carry them through the early, mechanical stages of their chess games. But they have gone on from there to reason and learn, and sometimes to win the game.There are other proofs that computers can be programmed to learn, but this example is sufficient to demonstrate the point. Granted, winning a game of chess is not an earthshaking eventeven when a computer does it. But there are many serious human problems which can be fruitfully approached as games. The Defense Department uses computers to play war games and work out strategies for dealing with international tensions. Other problems ----international and interpersonal relations, ecology and economics, and the ever-increasing threat of world famine ---- can perhaps be solved by the joint efforts of human beings and truly intelligent computers.56. The purpose of creating chess-playing computers is __________ .A. to win the world chess championB. to pave the way for further intelligent computersC. to work out strategies for international warsD. to find an accurate yardstick for measuring computer progress57. Today, a chess-playing computer can be programmed to __________ .A. give trillions of responses in a second to each possible move and win the gameB. function with complete data and beat the best playersC. learn from chess-playing in the early stage and go on to win the gameD. evaluate every possible move but may fail to give the right response each time58. For a computer to ―think‖, it is necessary to __________ .A. mange to process as much data as possible in a secondB. program it so that it can learn from its experiencesC. prepare it for chess-playing firstD. enable it to deal with unstructured situations59. The author’s attitude towards the Defense Department is __________ .A. criticalB. unconcernedC. positiveD. negativeBThe following are four resumes (简历) of four persons.Hannah Oyler21 Balsom St Ventura, CA 94120 (613)555–7236Objective To obtain a position as a photographer for a major metropolitan (大都市的) newspaper.Notable Achievements Time Magazine, Top Photos of the Year 1999 for California Wildfire Banaker; Excellence in Photography Fellowship, 1995.ExperienceVentura County Times Staff photographer, 1996—Present,Regular coverage included: Sports, Lifestyle, & Metro.

They took their present jobs soon after they left university.D. They want to obtain a position that is related to their majors.CThe first two stages in the development of civilized man were probably the invention of weapons and the discovery of fire, although nobody knows exactly when he acquired the use of the latter.The origin of language is also difficult to understand. No doubt it began very gradually. Animals have a few cries that serve as signals, but even the highest apes have not been found able to pronounce words, even with the most intensive professional instruction. The superior brain of man is apparently a necessity for the mastering of speech. When man became intelligent enough, we must suppose that he gradually increased the number of cries for different purposes. It was a great day when he discovered that speech could be used for describing and telling stories. There are those who think in this respect picture language appeared before oral language. A man could draw a picture on the wall of his cave to show in which direction he had gone, or what prey he hoped to catch. Probably picture language and oral language developed side by side. I prefer to think that language has been the most important single factor in the development of man.Two important stages came not so long before the dawn of written history. The first was the domestication of animals. The second was agriculture. Agriculture was a step in human progress to which there was nothing comparable until our own machine age. Agriculture made possible a huge increase in the number of the human species in the regions where it could be successfully practiced. These were, at first, only those in which nature fertilized the soil after each harvest. Agriculture met with violent resistance from the pastoral nomads (游牧民族), but the agricultural way of life was accepted in the end because of the physical comforts it provided.Another fundamental technical advance was writing, which, like spoken language, developed out of pictures, but as soon as it had reached a certain stage, it was possible to keep records and transmit information to people who were not present when the information was given.These inventions and discoveries ---- fire, speech, weapons, domestic animals, agriculture, and writing ----made the existence of civilized communities possible. From about 3000 B. C. until the beginning of the Industrial Revolution less than two hundred years ago there was no technical advance comparable to these. During this long period man had time to become accustomed to his technique, and to develop the beliefs and political organizations appropriate to it. There was, of course, a big extension in the area of civilized life. At first it had been confined to the Nile, the Euphrates, the Tigris and the Indus, but at the end of the period inquestion it covered much the greater part of the inhabitable globe. I do not mean to suggest that there was no technical progress during this long time; there was progress ---- there were even two inventions of very great importance, namely gunpowder and the compass ---- but neither of these can be compared in their power to such things as speech and writing and agriculture.63. According to the above passage, we can conclude that ___________.A. the use of fire and the domestication of animals made agriculture possibleB. progress was probably very slow when language first came into beingC. gunpowder and the compass are as important as speech in historyD. communication is the most important factor for human development64. From the article we can learn that agriculture ___________.A. was accepted as soon as it appearedB. is as great a step forward as our machine ageC. helped improve the techniques of domesticationD. at first helped make the land more suitable for crops65. Which is the right order of the appearance of the following things(a to e)?a. agricultureb. weaponsc. domestication of animalsd. written languagee. political organizationsA. c, a, d, b, eB. e, b, c, d, aC. b, a, c, d, eD. b, c, a, d, e66. Which of the following is the best title of the article?A. The Development of CivilizationB. Speech and CivilizationC. The Origin of LanguageD. The First Two StagesSection C (8%)Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.Have you got an addictive nature? Are you unable to stop yourself joining in with the latest obsession for collecting or doing something? This probably describes most of us because it's only human nature to not want to miss out on something that everyone else is talking about.Most fads arrive suddenly and enthusiasm for them spreads quickly. They become a talking point on social media; we read about them, give them a try and, before we know it, we are hooked. In the past, (67.)___________. Maybe you were the proud owner of a Rubik's cube, which became the best-selling toy of all time – around 350 million have been sold so far.Now, technology is driving the latest crazes. In some parts of the world, flavour of the month is Pokémon Go ---- a game that uses augmented reality, where little virtual monsters pop up onto your phone and you have tocatch them. And games such as Angry Birds and Minecraft are other crazes, available on smartphones and tablets that have been hard to put down.Our keenness to participate in crazes has been analyzed by experts. One of them, Dr Ben Michaelis, a clinical psychologist, explains that (68.)_____________and this "hooks into an ancient evolutionary fear of being left behind or abandoned by our tribes"; we have to join in or lose out.Although becoming addicted to a computer game might not seem like a 'benefit', (69.)_____________. It allows you to learn new skills and gives you something to talk about at parties!But fashions come and go and most fads are just a flash in the pan so if one of them is not your cup of tea, don't worry: (70.)_______________. Look at the addiction to the unsophisticated loom bands – those little rubber bands you could make jewelry and other things out of. For a brief period they were the must-have item for any schoolchild, now they're the bargain bucket item in a discount shop or worse still, trash filling up our landfill sites! What crazes have you been addicted to?第Ⅱ卷(共50分)I. Translation (15% = 3+3+4+5)Directions: Translate the following sentences into English, using the words given in the brackets.1. 我觉得食品安全问题在于法规和道德的缺失。
