2018年长宁区高考英语二模试题II. Grammar and VocabularySection AA Great FriendshipThomas Jefferson and James Madison met in 1776. Could it have been any other year? TheyJefferson wrote to his longtime friend. His words and Madison's reply remind us that friends are friends until death. They also remind us that sometimes a friendship has a bearing on things larger than the friendship itself, for has there ever been a friendship of greater public consequence than this one?po1itical principles and pursuits have been sources of constant happiness to me through that longvindicating to posterity the course that we've pursued for preserving to them, in all their purity, their blessings of self-government, which we had assisted in acquiring for them. If ever the earthgeneral interest and happiness of those committed to it, one which, protected by truth, can neverpillar of support throughout life. Take care of me when dead and be assured that I should leave with you my last affections."harmony with more affecting recollections than I do. 29 they are a source of pleasure to you, what aren’t they not to be to me? We cannot be deprived of the happy consciousness of the pure devotion to the public good with Which we discharge the trust committed to us and I indulgeafter we are gone, whatever of justice may be withheld whilst we are here. "He is kindlyThe other evening at a dancing club a young man introduced me to Mr. and Mrs. F. Scott Fitzgerald, and Scott seemed to have changed a lot from the first time I met him at Princeton, when he was an eager undergraduate trying his best to __31__ himself into a great author. He is still trying hard to be a great author. He is at work now on a novel which his wife __32__ me is far better than This Side of Paradise, but like most of our younger novelists he finds it __33__ toproduce a certain number of short stories to make the wheels go around. That The V egetable, his play, did not receive a Manhattan presentation seems to have disappointed rather than discouraged him. He is still __34__ light-hearted.I have always considered him the most brilliant of our younger novelists. Not one of them can tough his style, nor the superb quality of his satire(讽刺). He has yet to put them in a novel with carefulness of conception and __35__ of character. He can become almost any kind of writer that his peculiarly restless character will __36__.Born in St. Paul, he attended Princeton, served in the Army, wrote his first novel in a training camp, achieved fame and fortune, married a Southern girl, has a child and lives in New York. At heart, he is one of the kindliest of the younger writers. Artistry means a great deal to F. Scott Fizgerald, and into his own best work he __37__ great efforts. He demands this in the work of others, and when he does not find it he criticizes with passionate earnestness. I have known him, after reading a young fellow-novelist’s book, to take what must have been hours of time to write him a lengthy, careful __38__.Just what he will write in the future remains __39__. With a firmer reputation than that of the other young people, he yet seems to me to have achieved rather less than Robert Nathan and rather more than Stephen Vincent Benet, Cyril Hume. His coming novel should mean a definite prediction for future work. It is to be hoped that from it will be __40__ the seemingly unavoidable modern girls.III. Reading ComprehensionSection AStandards for Schools: Developing Organizational Accountability(绩效) Quality teaching depends on not just teacher’s knowledge and skills but on the environment in which they work. Schools need to offer a coherent curriculum focused on higher-order thinking and performance across subject areas and grades, time for teachers to work __41__ with students to accomplish challenging goals, opportunities for teachers to plan with and learn from one another, and regular occasions to evaluate the outcomes of their __42__.If schools are to become more responsible, they must, like other professional organizations, make evaluation and assessment part of their everyday lives. Just as hospitals have standing committees of staff that meet regularly to look at evaluation data and discuss the __43__ of each aspect of their work – a practice reinforced by their accreditation(评定) requirements, - schools must have regular occasions to examine their practice and effectiveness.As Richard Rothstein and colleagues describe in Grading Education: Getting Accountability Right, school-level accountability can be supported by school __44__, like those common in many other nations, in which trained experts evaluate schools by spending several days visiting classrooms, __45__ samples of student work, and interviewing students about their understanding and their experiences, __46__ looking at objective data such as test scores, graduation rates, and so on. In some cases, principals accompany the inspectors into classrooms and are asked for their own evaluations of the lessons. In this way, the inspectors are able to make __47__ about the instructional and supervisory competence(能力) for principals. As described earlier, inspectors may also play a role in ensuring the __48__ and comparability of school-based assessments (as in England and A ustralia), as well as school’s internal assessment and evaluation process (as in HongKong).In most countries’ inspection systems, schools are rated on the quality of instruction and other services and supports, as well as students’ __49__ and progress o n a wide range of aspects, including and going beyond academic subject areas, such as extra-curricular, personal and social __50__, the acquisition of workplace skills and the __51__ to which students are encouraged to adopt safe practices and a __52__ lifestyle. Schools are rated as to whether they pass inspection, need modest improvements, or require serious intervention(介入), and they receive extensive feedback on what the inspectors both saw and __53__. Reports are publicly posted. Schools requiring intervention are then given more expert __54__ and support, and are placed on a more frequent schedule of visits. Those that persistently fail to pass may be placed under local government control and could be __55__ if they are not improved.41. A. occasionally B. closely C. strictly D. peacefully42. A. challenges B. competence C. curriculum D. practices43. A. effectiveness B. faults C. progress D. requirements44. A. instruction B. protection C. inspection D. consideration45.

Scientists say the orbital debris, better known as space junk, poses an increasing threat to space activities. “ This is a growing environmental problem,” said Nicholas Jonson, the chief scientist and program manager for orbital debris at NASA(美国航空航天局) in Houston, Texas.Johnson and his team have developed a computer model capable of simulating past and future amounts of space junk. The model predicts that even without future rocket or satellitelaunches, the amount of debris in low orbit around Earth will remain steady through 2055, after which it will increase. While current efforts have focused o limiting future space junk, these scientists say removing large pieces of old space junk will soon be necessary.Since the first launch of satellite in 1957, humans have been generating space junk. The U.S. Space Surveillance Network is currently tracking over 13,000 human-made objects larger than ten centimeters in diameter orbiting t he Earth. “Of the 13 000 objects, over 40 percent came from breakups of both spacecraft and rocket bodies,” Johnson sand. In addition, there are hundreds of thousands of smaller objects in space. These include everything from pieces of plastic to bits of paint. Much of this smaller junk has come from exploding rocket stages. Stages are sections of a rocket that have their own fuel or engines.These objects travel at speeds over 35, 000 kilometers an hour. At such high speed, even small junk can tear holes in a spacecraft or disable a satellite by causing electrical shorts that result from clouds of superheated gas.Johnson believes it may be time to think about how to remove junk from space. Previous proposals range from sending up spacecrafts to grab junk and bring it down to using lasers to slow an object's orbit to cause it to fall back to Earth more quickly. Given current technology, those proposals appear neither technically nor economically practical, “Space junk is like any environmental problem. “Johnson admits. “It’s growing. If you don’t deal with it now, it will only become worse, and the solutions in the future are going to be even more costly.”56. What is this passage mainly talking about?A. Advanced technology is used to remove spaces junkB. NASA is responsible for the environmental problem.C. Cleaning up the space junk is greatly neededD. Human activities generate much orbital debris57. Which of the following is not mentioned in the passage?A. Rocket launches produce more debris than satellite launches Space Tech CultureB. Space junk is endangering human beings' space activitiesC. It's necessary to clean up the large pieces of old space junkD. Even a tiny piece of space junk can destroy a spacecraft58. What does John think of the previous proposals to grab space junk and bring it down to the earth?A. ReasonableB. UnbelievableC. ReliableD. Impractical(B)Eye Scan Technology Comes to SchoolsABC News: Parents who want to pick up their kids at school in one New Jersey district now can submit to iris(虹膜) scans, as the technology that helps keep our nation’s airports and hotels safe begins to make its way further into American lives.this high-tech security system on Monday with funding fromthe Department of Justice as part of a study on the system’seffectiveness.As many as four adults can be authorized to pickup each child in the district, but in order to be authorized tocome into school, they will be asked to register with the district’s iris recognition security and visitor management system. At this point, the New Jersey program is not a must.If someone tries to slip in behind an authorized person, the system causes an alarm and red flashing lights in the front office. The entire process takes just seconds.This kind of technology is already at work in airports around the country like Orlando International Airport, where the program has been in operation since July. It has 12,000 subscribers who pay $79.95 for the convenience of submitting to iris scans rather than going through lengthy security checks.An iris scan is said to be more accurate than a fingerprint because it records 240 unique details—far more than the seven to twenty-four details that are analyzed in fingerprints. The chances of being misidentified by an iris scan are about one in 1.2 million and just one in 1.44 trillion if you scan both eyes.Phil Meara, the Freehold District official, said that although it was expensive, the program would help schools across the country move into a new frontier in child protection. “This is all part of a larger emphasis, here in New Jersey, on school safety,” he said. “We chose this school because we were looking for a typical slightly urban sch ool to launch the system.”Meara applied for a $369,000 grant on behalf of the school district and had the eye scanners installed in two grammar schools and one middle school. So far, 300 of the nearly 1,500 individuals available to pick up a student from school have registered for the eye scan system.59. Why does the Freehold Borough School District adopt the eye scan security system?A. To ensure the school safety and efficiency of picking up children.B. To encourage more students to register in New Jersey urban schools.C. To test the effectiveness of school security and management system.D. To collect the information of the children and their beloved parents.60. What’s the advantage of the eye scan system over fingerprints?A. Having many more subscribers throughout the country.B. Authorizing the adults to pick up children more flexibly.C. Attracting parents in a larger proportion to register for it.D. Making almost no mistakes in identifying the authorized.61. How does Phil Meara help to protect the safety of children?A. By asking people to register with the security system.B. By applying for grant to install eye scanners in schools.C. By asking the department of justice to fund this program.D. By turning to Orlando International Airport for help.62. What is the best title of this passage?A. Parents Favor the Eye Scan SystemB. Security Management Needs Improving.C. High Technology Comes to SchoolD. Iris Scanners are Invented in the Country.(C)Dusty Nash, an angelic-looking blond child of seven, awoke at 5 one recent morning in his Chicago home and began to throw a fit. He cried and kicked. Every muscle in his 50-1b. body flew in violent motion. Finally, after about 30 minutes, Dusty Pulled himself together sufficiently to head downstairs for breakfast. While his mother was busy in the kitchen, the extremely excited child pulled a box of Kix cereal from the cupboard and sat on a chair.But sitting still was not easy this morning. After grabbing some cereal with his hands, he began kicking the box, scattering little round com puffs across the room Next he turned his attention to the TV set, or rather, the table supporting it. The table was covered with a check-board Con-Tact paper, and Dusty began peeling it off. Then he became interested in the spilled cereal and started smashing it into bits.It was only 7:30, and his mother Kyle Nash, who teaches a medical-school course on death and dying, was already feeling half dead from exhaustion. Dusty was to see his doctors that day at 4, and they had asked her not to give the boy the drug he usually takes to control his extreme excitement and attention problems, a condition known as attention deficit hyperactivity disorder (ADHD). It was going to be a very long day without help from Ritain, a powerful drug which some people take for pleasure, but which they can become addicted to.Karenne Bloomgarden remembers such days all too well The spirited, 43-year-old boss and gym teacher was a disaster as a child growing up in New Jersey. I did very poorly in school \wereconstantly on her case for tough behavior. \They just felt I was being bad---too loud, too physical, too everything \diagnosis\The athletic Bloomgarden managed to get into college, but she admits that she cheated her way to a diploma \she did fine in physically active jobs but was anxious about administrative work. Then, four yeas ago, a doctor put a label on her troubles: ADHD. “It's been such a weigh off my shoulders\says Bloomgarden, who takes both stimulant Ritalin and the antidepressant Zoloft to improve her concentration. “I had 38 years of thinking I was a bad person. Now I'm rewriting the tapes of who I thought I was to who I really am.”63. What does the phrase “throw a fit” in the 1st paragraph probably mean?A. turn oneself around casuallyB. fall down to the ground carelesslyC. lose one's temper suddenlyD. shout and complain loudly64. Why did Dusty Nash mess the room?A. He was reluctant to listen to his motherB. He couldn’t focus on anything f or a whileC. He forgot to take the medicine he usually tookD. He was afraid to see the doctor with his mother.65. The passage is chiefly concerned with _______________A. the visible symptoms of the disease ADHDB. the precise definition of the disease ADHDC. Dusty's experiences in his childhood and collegeD. Karenne's confessing of cheating to get a diploma66. What can be inferred from the passage?A. Dusty went to see his private doctor every week in the past years.B. Dusty's mother took care of him till he was admitted to a collegeC. A psychologist examined Karenne and cured her serious disease.D. Karenne didn't know herself well until she was diagnosed with ADHDThe Minoans: A Forgotten PeopleThe first advanced culture in ancient Greece was the Minoan culture. For thousands of years,knowledge of these people survived only in Greek myths. In the late 19th century, archaeologists began to unearth ruins. This inspired Arthur Evans to begin digging on the island of Crete near mainland Greece. On a dig in Kbossos, Evans found an ancient palace. Experts think that it was the palace of King Minos, a central figure in many Greek myths.____67____ With his team, he uncovered a vast structure, varied works of art, and many hieroglyphic records, These finds, together with later finds, comprise all that experts know about Minoan culture.From the evidence experts gathered, it is clear that the Minoans were ahead of their time. The palace at Knossos was five floors high with hundreds of rooms. Buildings throughout the ancient city had plumbing and flush toilets. Stone pavement lined the surfaces of the roads. In addition, the Minoans possessed a highly developed naval fleet for long-distance trade. ____68_____ These records confirm the central role of commerce in culture.Expert analysis of the evidence also offers insight into some aspects of Minoan society. ____69____ Ruins and artwork suggest that people of all classes enjoyed a high degree of social and gender equality. Religious icons show that Minoans worshiped bulls, the natural world, and many female gods.An unusual feature of Minoans culture was the pursuit of leisure interests. Sport and visual arts were central to Minoan life. Boxing and bull jumping, a sport in which players jumped over live bulls, were popular. Although bull jumping may have served some ritual purpose, experts believe that it was done mostly for fun. Similarly, although some works of art showed political and religious themes, other works served only as pleasant décor(装饰品). ____70_____ The Minoans met their demise after a series of natural disasters. Experts believe that group from the Greek mainland capitalized on these events and looked over the island.IV. Summary WritingThe Conflict of the OrdersThe types of people who served as officials in the Roman government changed over time. These changes stemmed from the attempts of common people to more rights. The struggles became known as the Conflict of the Orders.In the early republic, Romans were divided into two classes of people: patricians and plebeians. Patricians were powerful landowners who controlled the government. As nobles, they inherited their power. Plebeians, who made up most of the population, were mainly farmers and workers. For many years, plebeians had few rights. They could vote, but they were barred from holding most public offices. Plebeians could not even know Roman laws because laws were not written down. In court, a judge stated and applied the law, but only patricians served as judges.Over time, plebeians increased their power through demand and strikes. They gained the right to join the army, hold government office, form their own assembly, and elect leaders. In one of their greatest victories, they forced the government to write down the laws of the Roman Republic. In about 450, B.C. the Romans engraved their laws on tablets called the Twelve Tables. The laws were placed in the Forum, the chief public square, for all to view.The first plebeians were appointed to the government in the late 400s B.C. After 342 B.C., a plebeian always held one of the consul positions. By about 300 B.C. many plebeians had become so powerful and wealthy themselves that they joined with patricians to form the Roman nobility.From that time on, the distinction between patricians and plebeians was not a important. Membership in the nobility was still very important, however, since government officials were not paid a salary, only wealthy nobles could afford to hold office. Thus, the nobles still controlled the republic.V. Translation72. 我们必须尽快适应新环境。

一、现代文阅读(一)论述类文本阅读阅读下面的文字,完成下列小题。

草原文化精神从根本上说是一种动态的、积极的、以个体奋斗为主要内容的进取性文化。

北方草原具有独特性,它既有深远悠长的民族牧歌情调式的生活方式,又有严酷杀伐的沧桑、厚重的历史,从而导致了草原民族对于人与自然关系方面的特殊认识。

一方面,人与自然的关系极为直接、密切,人对自然的依赖性突出,因而对自然的亲近之感、迫近之念、忧虑之情更为突出、深挚;它不似江南山水对人的细膩轻抚,更不像士子优游于小桥流水,流溢着别致而精微的艺术感触,而是将民族生存与自然环境直接联系起来,把对草原的关切与民族的整体性发展联结起来,发出了“草原不在、民族何存”的呐喊,汉代流传的《匈奴歌》就是其中代表。

另一方面,人与自然架构起初步的生态美学桥梁。

蒙古民族第一部史传文学《蒙古秘史》当中就显现着极为浓郁的生态观念。

由于生存环境的严酷、险恶、千变万化,草原民族“逐水草而居”的动态生存观念异常鲜明。

草原民族生存的“动态”和“变化”的特点使人的适应能力和冲破自然环境束缚的能力分外突出。

草原民族强调人在强大的自然环境和社会面前的力量、智慧、意志力,从而形成一种对英雄的崇拜的观念。

《史记·匈奴列传》中的冒顿单于和《蒙古秘史》中的札木合就是鲜活的例证,只不过后者还显现着强烈的崇信重义之美。

ALife experiences can show one’s “grit”(坚韧). Complex challenges early in life helped the following people develop skills that got them to the top of their professions.Ursula Burns, Chairwoman, VEON; Former CEO, XeroxHer family was so poor that her single mother traded office cleaning for health ca re.But Burns’ early gift for maths won her a scholarship and an internship at Xerox, where she would compete her way to the top. “ I'm a black lady from the Lower East Side,” she says, “Not a lot scares me.”Howard Schultz, Executive Chairman, StarbucksSchultz grew up in public housing in Brooklyn, surrounded by poverty, and was the first in his family to go to college (on a football scholarship).After training in sales, he set up the company that would later buy Starbucks. “In the course of the year I spent trying to raise money, I spoke to 242 people, and 217 of them said no.” he said.Sean Combs, CEO, Sean JohnCombs began a generation of hip-hop talent and made a lasting influence on fashion.But he story could have turned out much differently: His drug dealer father was killed when he was3. “It made me work even harder.” he recently said.Geisha Williams, CEO, PG&EHer parents fled Cuba when Williams was 5. By 7, she was her parents main translator in talks with lawyers and accountants at grocery stores they owned.The experience did help her. “I went from thinking I could be a manager to thinking I could do something much bigger.” she told Fortune.21.Who did best in math at school?A.

However, it's almost a habit of mine to have photos taken thoughtlessly. Thus, photos have been piling up in my childhood to womanhood. In spite of that, those black-and-white pictures taken in my early years are rarely kept, except a few survivals regarded as antiques.The bald(秃头的) baby picture of me that I treasured, the only one left, it's now missing.Familiar faces flash one by one before my eyes. Though the world is so small and we all live in it, yet we are separated by physical and psychological distances, some smaller, some larger.With the passage of time, one cannot, regretfully relive(重温) it with the same feeling as one had in the picture.What one can get from the old photos is but a bit of the past joy.One takes pictures with different persons in different time and places.They fill one with nostalgia(怀旧) in various degrees--some more, some less, and others none.That's why one has conflicting feelings towards the old photos. Still kept with the current ones, they're even less favored than a daily-used cup, which is always close to the owner.How these pieces of thought influence me. Photos keep our images ratherowner, whom the photo can't keep ,neither can it keep the event.Of course, there are some of the photos still holding my affection, such as those taken with my family members, with favorite playmates, fellow girl-students and best friends, not only in pictures but also in my life and heart.Now, since I have learned all this, I will not allow myself to be included casually in a photo taken with others.

This language that resembles English is called Singaporean E n g l i s h o r S i n g l i s h.The New York Times calls Singlish “patchwork” because Singapore consists of migrants(移民) from several countries including China, India and Malaysia, and they all speak their ow n versions of “English”.“Everyone who speaks it shapes it,” wrote the newspaper.For example, in Singlish, you can easily recognize influences from Chinese, including vocabulary such as” Mee Siam” and “da bao”. Sentence structures like ” toilet where” instead of “where’s the toilet” also come from Chinese.Interesting and diverse as it may seem, the trend for Singlish is worrying Singapore’s government. It is concerned that the dialect is lowering the country’s English standard and may affect its relations hip with visitors.It even started the Speak Good English Movement.Unfortunately, the problem was not solved. Instead, Singlish has boomed, especially among young people who think of it as a sign of being cool and a way of identifying themselves as Singaporean.But this does not mean that standard English is being abandoned by young people. In fact, they are much more capable than the government gives credit--they can speak both.“We are a nation good at code switching-- we know that the way we speak to friends or drivers must be different from how act at work or school,” wrote Cheryl, a Singaporean author, in Time magazine, “To actively urge us to give up a language that speaks to the very heart of who we are, that's so beautifully represents the melting pot of Chinese, Indians, Malaysians and Eurasians that we are, is shortsighted, surely.”28 Why does Singapore have many different versions of English?A It is made up of migrants.B It is highly westernized.C It is influenced by Chinese.D It is affected by official languages.29 What is the purpose of starting the Speak Good English Movement?ATo stop the new trend.B To better the relationship.C To keep the English standard.D To give the government credit.30 What do the young people think of Singlish?A It’s interesting.B It’s their identity.C It’s a sign of status.D It’s a way of code-switching.31 What can we learn from what Cheryl said?A Different people speak different styles of Singlish.B Singlish is a more beautiful language than others.C People speaks Singlish only to friends and drivers.D People can use Singlish to express themselves well.DLong before iphones, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.Of course, technology does not yellow your teeth, cause disease or lead to cancer. But some individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colors on their screens to a less tempting scale of gray.The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move can make the social network more homely.Last year the tech industry got a bad name- Big Tech-with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders(股东) that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world--connecting old friends and giving space for people to share their ideas--from the bad.In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo(禁忌),we can warn parents against losing themselves in their smartphones while taking care of kids.We can also create no-smartphone zones at dinner. Eventually smartphones could be banned from all public places and help us give our attention to the people around us instead.32 How did people keep close relationships with others in the past?A By smoking.B By drinking.C By phoningD By dining out.33 Why is the tech industry called Big Tech?A It plays a bad role in the world.B It is as big as Big Tobacco.C It has an unfortunate name.D It is a giant in Silicon Valley.34 What can we infer from Franklin Foer’s argument about the tech?A It promotes social development.B It is still favored by some people.C It is worse than Big Tobacco.D It offers continuing nutrition.35 Which can be the best title for the passage?A Creating a No Smartphone LifeB Smartphones Enrich Our Social LifeC Smoking Does Greater Harm Than Smartphones DoD Quitting Smartphones Is the New Quitting Smoking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,选项中有两项为多余选项。

After years of wars,the officials trembled with fear when fighting was mentioned,and no one dared to speak of resistance(抵抗).Most of the officials persuaded the king to sue for peace(求和),at the cost of giving away Qin the large area ofland north of the Yellow River and south of the Taihang Mountain.However,Su Dai,a counsellor(谋士),did not agree.He told a story."once there was a man whose house was on fire.People told him to put out the fire with water.But instead he carried a faggot(柴捆),which only made the fire fiercer,to put out the fire.As the same,Qin will never stop attacking us until our land is totally given away.If you agree to sue for peace at the cost of the land,isn't it the same as carrying faggots to put out a fire?" Although Su Dai's words were reasonable,the king of Wei only wanted the peace at that moment,so he did what other officials suggested.In 225 AD,Qin attacked Wei again,just like Su Dai forecasted.42.According to the word " trembled" in the second paragraph,we can infer that the officialsin the state of Wei were ______ .A. afraidB. gentleC. excitedD. careful43.What's the best title of Su Dai's story?______A.
