一、语言文字运用（15分）1．在下面一段话的空缺处依次填入词语，最恰当的一组是（3分）在很多人看来，纪检干部，“老纪检”的脸上却总挂着笑容。

经他查办的大案要案很多，有些至今还被业内同行。

“老纪检”说，诱惑时常有，一不小心就容易栽跟头，可，既然选择了纪检事业，就不能有发财的念头，与民争利的事更不能干。

A．不苟言笑啧啧称奇出水才看两腿泥B．谨言慎行啧啧称奇锥子没有两头尖C．谨言慎行津津乐道出水才看两腿泥D．不苟言笑津津乐道锥子没有两头尖2．下列各句中，没有．．语病的一项是（3分）A．就社会效果而言，《中国诗词大会》等节目热播不仅带动了《诗经》等传统文化类图书阅读升温，还引发了同名书籍的持续热销。

B．工商资本下乡，应该带动农民而不是代替农民，把“老板”与“老乡”的优势结合起来，让农民通过土地等资源获得应有利益。

D．长期以来，海上丝绸之路沿线国家受到地震、海啸、洪水、风暴潮等诸多自然灾害，迫切需要利用大数据来提高自身的减灾应对能力。

3．下列语段空缺处应填入的语句，排列正确的一项是（3分）《七月》是一份集体的、或曰“大我”的回忆。

因为是回忆，所以思绪是流动的，叙述是跳荡的。

一根或起或伏、若明若暗的线，牵绾起活泼的思绪、跳荡的旋律。

《七月》追述春夏秋冬的故事，却不是记录春夏秋冬的《月令》；铺叙一岁耕桑的苦乐，却不是安排耕种与收获的农书。

因为是“大我”，所以它可以包容无数的“小我”。

它是阳刚的，却不妨阳刚中有阴柔。

它尽可以在一个大结构中，细心经营一个一个的小结构。

willensure you can succeed，" declared the British prime minister， on October 26th，as he introduced plans to tackle discrimination in the workplace． Ten big employers in the public and private sectors-including the civil service， HSBC and Deloitte-have agreed to start recruiting（招募）on a "name-blind" basis in Britain；others may also follow suit． In such schemes， those [drawing up] shortlists of applicants cannot see their names， with the aim of reducing racial and sexual bias． But do they work？Several countries have experimented with name-blind applications． In 2010Germany's Anti-Discrimination Agency， an advisory body， sponsored a voluntary scheme to get businesses to try it． In France a law passed in 2006 made the anonymizing of applicants' CVs compulsory for firms of over 50 employees． But the government was slow in laying down the conditions for how the law would operate，and only started performing it last year．In Sweden and the Netherlands there have been some trials． Discrimination against job applicants based on their names is well documented， particularly among ethnic minorities． An experiment in Germany found that candidates with German-sounding names were 14% more likely to be called for an interview than candidates with Turkish ones． A review of various studies， by the Institute for Study of Labour （IZA）， a German outfit， found that anonymized job applications boost the chances of ethnic minority candidates being invited to an interview． A Sweden study found that it led to more ethnic-minority people being hired．However， the results from other trials are less clear． A second Swedishexperiment found that only women， not immigrants， were boosted by anonymous recruitment． According to the IZA， experiments in the Netherlands showed no increase in the likelihood of ethnic-minority candidatesbeing offered a job iftheir CVs were seen anonymously， suggesting that discrimination had slid in at the interview stage． Ensuring that a candidate is completely anonymous is also tricky．A 2012 French study found that foreign-born candidates and those from poordistricts were less likely to be called for interview when applications were anonymized． Its authors suggested that recruiters may have used other indicators，such as knowledge of Arabic， to identify race． In places suffering from religious tension， such as Northern Ireland， the name of a school can reveal a candidate's faith， while a few years missing on a CV may suggest maternity leave（产假）， and thus that the candidate is female． Going name-blind when shortlisting candidates may be a sensible start， but it is likely to be just a small step towards ending hiring bias．58． What can learn from the passage？A． In France， the government started the anonymized recruitment in 2006．B． In Germany， chances of ethnic-minority name-blind candidates being interviewed are slighter．C． In the Netherlands， the anonymous recruitment is more of a trick than an effective practice．D． In Sweden， not only women but also immigrants may well enjoy a higherrecruitment rate．59． What does the underlined phrase "drawing up" in paragraph 2 mean？A． writing outB． taking inC． making upD． picking out60． By writing the passage， the author tries to ．A． inform readers of the idea of anonymizing job applicationsB． explain how anonymization in recruitment is operatedC． discuss whether anonymization in job applications worksD． promote the strategies of name-blind recruitment29．(★★★★)SAN FRANCISCO---When you pull the headset over your eyes and the game begins， you are transported to a tiny room with white walls． Your task is to break out of the room， but you cannot use your hands． There is no joystick or game pad． You must use your thoughts．You turn toward a ball on the floor， and your brain sends a command to pick it up． With another thought， you send the ball crashing into a mirror， breaking the glass and revealing a few numbers on a wall． You mentally type those numbers intoa large keypad by the door． And you are out．Designed by Neurable， a small startup founded by Ramses Alcaide， an electrical engineer and neuroscientist （神经科学家）， the game offers what you might call a computer mouse for the mind， a way of selecting items in a virtual world with your thoughts．Combining a headset with virtual reality goggles and sensors that can read yourbrain waves， this prototype （样机） is a few years from the market． And it is limited in what it can do． You cannot select an object with your mind unless you first look in its direction， narrowing the number of items you may be considering．But it works． I recently played the game， which has the working title Awakening，when Alcaide and two Neurable employees passed through San Francisco， and a few hundred others tried it this month at the Siggraph computer graphics conference in Los Angeles．[The prototype is among the earliest fruits of a widespread effort to embrace technology that was once science fictionand in some ways still is]． Driven by recent investments from the US government and by the herd mentality （从众心理） in the tech world， a number of startups and bigger companies like Facebook areworking on ways to mentally control machines． They are also looking for smoother ways to use virtual reality technology． The increased interest in neurotechnologyis partly a result of an effort the government administration started in 2013． The initiative helped create significant government financing for brain-interface companies and related work in academy．The Neurable prototype shows what is possible today． Using electroencephalography，or EEG---a means of measuring electrical brain activity that has been around for a decade---the company can provide simple ways of mentally interacting with agame． Some companies hope to go much further and want to build ways of performing nearly any computing task with the mind． Imagine a brain interface for rapidly typing on a smartphone．At Neurable， which is based in Boston， Alcaide and the member of his team are pushing the limits of EEG headsets． Although sensors can read electrical brain activity from outside the skull， it is very difficult to separate the signal from the noise． Using computer algorithms （算法） based on research that Alcaide originally published as a doctoral student at the University of Michigan， Neurable works to read activity with a speed and accuracy that is not usually possible．The algorithms learn from your behavior． Before playing the game， you train them to recognize when you are focusing your attention on an object． A pulse of light bounces around the virtual room， and each time it hits a small colored ball in front of you， you think about the ball． At that moment， when you focus on the light and it stimulates your brain， the system reads the electrical spikes of your brain activity． "Once we understand them， we can use them．" Alcaide expects．61． Which of the following is TRUE about the design of the game？A． You can break the glass with a simple click of the mouse．B． You can select as many items around you as you like．C． The game has boosted the government revenues since its release．D． The game can't work without sensors and virtual reality technology．62． What can be inferred from the underlined sentence in Paragraph 6？A． What was a fantasy is coming true with technology．B． Whatever efforts you make might not fruit success．C． Science fiction leads to the development of the prototype．D． The technology behind the prototype enjoys wide popularity．63． What can we learn from the last paragraph？A． It's not uncommon that we usually have different voices in mind．B． There's still a long way to go before the game is fully matured．C． The Alcaide team focuses on limiting the usage of headsets．D． It's impossible for Alcaide to read activities fast and accurately．64． What might be the best title of the passage？A． A game controlled with mindB． A machine leading to the futureC． Neurable： king of tomorrowD． Neurology： a cutting-edge zone30．(★★★★★)Miss Martha， aged 40， kept a little bakery on the corner．Two or three times a week a customer came in in whom she began to take an interest． He spoke English with a strong German accent． His clothes were worn and darned in places， and wrinkled and baggy in others． But he looked neat， and had very good manners．[1．He always bought two loaves of stale bread．]Fresh bread was five cents a loaf． Stale ones were two for five． Never did he call for anything but stalebread．Once Miss Martha saw a red and brown stain on his fingers． She was sure then that he was an artist and very poor． No doubt he lived in a attic painting pictures and ate stale bread．Often when Miss Martha sat down to her chops and light rolls and jam and tea she would sigh， and wish that the gentle-mannered artist might share her tasty meal instead of eating his dry bread．In order to test her theory as to his occupation， she brought from her room oneday a painting that she had bought at a sale， and set it against the shelvesbehind the bread counter．Two days afterward the customer came in．"Two loafs of stale bread， if you please．"A fine picture， madam，" he said while she was wrapping up the bread．"Yes？" says Miss Martha "I do admire art． You think it is a good picture？""Der balance，" said the customer， is not in good drawing． Then he took his bread，and hurried out．How and kindly his eyes shone behind his spectacles! To be able to judgeperspective at a glance -- and to live on stale bread! But genius often has to struggle before it is recognized． She thought he began to lookthinner．[2． Her heart ached to add something good to eat to his meagre purchase]， but her courage failed at the act． She did not dare affront him． She knew the pride of artists．Miss Martha took to wearing her blue-dotted silk waist behind the counter． In the back room she cooked a mysterious compound of quince seeds and borax．One day the customer came in as usual， and called for his staleloaves．[3． While Miss Martha was reaching for them， a fire-engine came lumbering past． ]He hurried to the door to look， as any one will． Suddenly inspired， Miss Martha seized the opportunity． With a bread knife Miss Martha made a deep slash in each of the stale loaves， inserted a generous quantity of butter，and pressed the loaves tight again．When the customer turned once more she was tying the paper around them．When he had gone， after an unusually pleasant little chat， Miss Martha smiled to herself． For a long time that day her mind dwelt on the subject． She imagined the scene when he should discover her little deception．He would prepare for his luncheon of dry bread and water． He would slice into aloaf -- ah!Miss Martha blushed． Would he think of the hand that placed it there as he ate？Would he？The front door bell jangled viciously． Somebody was coming in， making a greatdeal of noise．Martha hurried to the front． Two men were there． One was a young man smoking a pipe -- a man she had never seen before．[4． The other was her artist．]His face was very red， his hat was on the back of his head， his hair was wildly rumpled． He clinched his two fists and shook them ferociously at Miss Martha． AtMiss Martha．"Dummkopf!" he shouted with extreme loudness； and then "Tausendonfer!" or something like it in German．Miss Martha leaned weakly against the shelves and laid one hand on her blue-dotted silk waist． The young man took the other by the collar．"Come on，" he said， "you've said enough．" He dragged the angry one out at the door to the sidewalk， and then came back．"Guess you ought to be told， ma'am，" he said， "what the row is about． That's Blumberger． He's an architectural draftsman． I work in the same office with him．"He's been working hard for three months drawing a plan for a new city hall． It was a prize competition． He finished inking the lines yesterday． You know， a draftsman always makes his drawing in pencil first． When it's done he rubs out the pencil lines with handfuls of stale bread crumbs． That's better than India rubber．"Blumberger's been buying the bread here． Well， to-day -- well， you know， ma'am，that butter isn't -- well， Blumberger's plan isn't good for anything now except to cut up into railroad sandwiches．"Miss Martha went into the back room． She took off the blue-dotted silk waist and put on the old brown serge she used to wear． Then she poured the quince seed and borax mixture out of the window into the ash can．65． Why did the customer always buy two loaves of stale bread？A． Because he was to poor to afford better ones．B． Because the bread was more delicious and to his taste．C． Because the bread had a special usage for his work．D． Because he wanted to create chances to see Miss Martha．66． Which of the following can best describe Miss Martha？A． Sympathetic， dreamy and decisiveB． Disciplined， ambitious and generousC． Proud， sensitive and conservativeD． Practical， dependable and diligent67．What does the "blue-dotted silk waist" symbolize？A． Miss Martha's fine appreciation for art．B． Miss Martha's affection for the customer．C． Miss Martha's strong sense of ceremony．D． Miss Martha's confidence in her baking skills68． Which of the following sentences best forwards the plot？A．①B．②C．③D．④69． Which of following sentences indicates the change of Miss Martha's feelings A． Curious→ excited→ lost→ relived．B． Curious→ hopeful→ frustrated → calm．C． Nervous→ delighted→ disappointed→ angry．D． Nervous→ satisfied→frightened→depressed．70．

exist inside or outside the home． Any well-lit place inside your home makes a suitable environment． Indoor herb gardens are growing in popularity and thrive well in sunny kitchens． Any outside wall does as well． Green or living walls are beneficial to us in so many ways． I will discuss below， in simple terms， how these vertical gardens can protect your home and environment， save you energy and benefit your health．Pollutants exist all around us both outdoors and indoors． Toxic fumes（有毒气体）go into the air we breathe through our air systems and can cause what we commonly call "Sick Building Syndrome" Green or living walls can significantly clear up the toxins． While all plants absorb pollutants， there are certain plants that do so with much more efficiency． Even one plant can remove toxins from your home or building． However， the more plants are added， the more toxins are absorbed．The plantings prevent dramatic temperature variation， which then prevents the building from corrosion（腐蚀） that results from expanding and contracting during extreme temperatures． These plants act as a natural insulation， keeping airinside the buildings cooler in the summer months and warmer during the winter months． The manner in which these vertical gardens are constructed allows the building to breathe and protects the walls from wind， harmful UV rays and corrosive rain． Besides， living walls and green roofs help to provide a natural environment for birds and butterflies．Simply put， the plants on the building's exterior keep the building protected from the heat of the sun， thus keeping the building itself cooler so that less energyis employed when you are cooling the building． Interior green walls also greatly help to reduce energy use by helping to keep the interior cool． With each additional plant， energy consumption is reduced． Therefore， a room with hundreds of plants can see a temperature reduction of as much as 7℃． This is indeed significant! During the cold winter months these green walls have the opposite effect and act as insulation from bitter temperatures． The additional layer prevents heat from escaping， thus helping you to consume less gas or or oil．Plants offer instant stress relief by softening the environment around us． They reduce noise and pollution． Gardens have an instant calming effect． In workplaces plants have been exploited to increase productivity， in the home they increasepeace． They ease stress and tiredness， and offer rich oxygen． Gardens are strategically placed in hospitals for their calming benefits， which can lead to a patient's shortened stay． Try doubling the health benefits by building an eatable living wall in your kitchen． Absolutely， these greens will relax you and purify the air you breathe．With so many benefits， why not build your own living wall？第五部分书面表达（满分 25 分）32．(★★★)请认真阅读下面有关"不同年龄达到不同能力巅峰"的研究结果，并根据要求用英语写一篇 150 字左右的文章．"At almost any given age， most of us are getting better at some things and worse at others，" Joshua Hartshorne， an MIT cognitive science researcher and the lead author of a study looking at how intelligence changes as we age， told Business Insider． The team behind that study quizzed thousands of people aged 1090 on their ability to do things like remembering lists of words， recognizing faces． Their results suggest that no matter what your age， there's almost always a new peak on the horizon．【写作内容】1．用约 30 个单词概述图表和上文的主要内容；2．用约 120 个单词发表你的观点，内容包括：（1）谈谈"不同年龄达到不同能力巅峰"这一研究发现的意义（至少两点）；（2）结合自身实际，说明如何在现阶段把握你的优势．【写作要求】（1）须表明个人观点，同时提供理由或依据；（2）阐述观点或提供论据时，不得直接引用原文中的句子；（3）文中不能出现真实姓名和学校名称；（4）不必写标题．【评分标准】内容完整，语言规范，语篇连贯，词数适当．。
