（3）李白在《梦游天姥吟留别》中描绘天姥山夜间猛兽震憾人心的吼声：_______________，_______________。

2．按要求选择。

（4分）（1）下列各项中没有歧义的一句是（）A．每周一的早晨，我们都能看见校门一边站着一位同学，迎接师生们入校。

B．她是传奇人物，她是脱口秀女王，她的故事讲不完。

C．暑假期间，两个师范大学的女生自愿前往贵族苗寨担任指导教师。

D．局里刚到一批保密材料，为保证材料安全，他只能在机要室阅读。

（2）秋日午后，满园桂香，你信步其中，哪句诗描绘此时景物最合适（）A．绿玉枝头一粟黄，碧纱帐里梦魂香，晓风和月步新凉。

B．桂子月中落，天香云外飘，霜薄花更发，冰轻叶未凋。

C．暗淡轻黄体性柔，情疏迹远只香留。

D．南中有八树，繁华无四时，不识风霜苦，安知零落期。

二、阅读（70分）（一）阅读下文，完成3~8题。

（17分）上帝、数据和故事（有删改）（1）关于“大数据”的名言：“除了上帝．．．．，任何人都必须用数据来说话。

”（2）在这句话中，大数据俨然成了一个新的“上帝”，人容易在如此理解里被大数据所管控，不时地失去自我主体位置，最终导致认知和改造世界的迷惘与失误。

（3）通俗理解，“大数据”即是“大量”的数据。

它解决了以往小部分数据时，必须由局部去推测整体的困难。

如在大海航行时，航行者发现冰山一角，以往必须借助某种“算法”，去推测冰山的大小；在冰山“大数据”可得到时，整个冰山便容易把握，航行者不需要任何“算法”去推测。

而且，如果数据可以“大”到无所不包的“全量”时，人类就能够大大地提高趋利避害的准确性。

For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.Time to fight gaming problemIf you’re a gamer constantly ___21___（glue）to your phone, it could be time to ask for medical help. On June 18, the WHO officially listed“gaming disorder”___22___ a mental illness, like drug or gambling addiction.Video gaming is like a non-financial kind of gambling from a psychological point of view. Gamblers use money as a way of keeping score, ___23___ gamers use points.However, playing your favorite game every now and then is no reason to be worried. People need to understand this doesn’t mean every child who spends hours playing games ___24___（be）an addict, otherwise doctors ___25___（flood）with requests for help.But according to the WHO, ___26___ you lose control over your gaming habits and put gaming above everything else in life, you should be prepared to face serious problems. According to a study published by China Youth Day in July, about one in five young Chinese play online video games for at least four to five hours per day.Thankfully, measures have been taken ___27___（address）the problem. In April, the Ministry of Education issued a notice asking Chinese schools and parents to prevent students from becoming addicted to the Internet and games.Other countries have also taken action. In 2011, South Korea passed a“shutdown law”to stop children under the age of 16 from playing video games between the hours of midnight and 6 am. Meanwhile, in Japan, some mobile phones have a special mode for children ___28___ lets their parents control what games they can download and ___29___ ______ they can play them for. In the United States, the Entertainment Software Rating Board, a nonprofit organization, puts age restrictions on most games, ___30___（mean）the children under a certain age are unable to buy them.Section BDirections：Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.College degrees still necessary?We’re often told that if we can’t graduate from university, we’re unlikely to land a good job. However, some big-name companies say that you don’t need a college degree to do well in life.According to a list released by job review platform Glassdoor in August, a total of 15 famous companies have ___31___ college degrees as a requirement for some of their jobs, including Apple, Google, IBM, and Starbucks.The phenomenon of requiring a college degree for a position that actually doesn’t need it is called degree inflation （膨胀），according to Forbes. About 6 million jobs in the US are potentially ___32___ to degree inflation, according to a report released by Harvard Business School in 2017.This is because many employers regard having a college degree as equal to ___33___ a variety of soft skills.“Especially at a time when recruiters（招聘人员）complain that workers lack ___34___ soft skills—the ability to solve problems, work in teams and communicate—college is seen as the place that develops such abilities,”Jeffrey J. Selingo, a professor of practice at Arizona State University, US, wrote on The Washington Post.However, for some companies, a college degree doesn’t ___35___ that an applicant is a good performer.“They did some research and they saw that the individual strengths and future ___36___ rather than the academic performance of those they hired were a greater ___37___ of success in working at the firm,”Larry Nash, EY’s US director of recruiting, told Fast Company. EY, a UK-based finance company, dropped the requirement for a college degree when seeking hires in the UK in 2015.Meanwhile, in many tech sector positions, ___38___courses and on-the-job experience are more meaningful than a college degree, Ginni Rometty, CEO of IBM, told Quartz.However, this doesn’t mean a college degree is completely useless. Indeed, a college degree is still considered when ___39___ a job candidate, but it“no longer acts as a ___40___ to getting a foot in the door,”Maggie Stilwell, a recruitment expert at EY, told HuffPost.For some companies recent college graduates are no better than people who learned the same skills by themselves. As Quartz put it,“What a person knows is more important than how they learned it.”Ⅱ. Reading ComprehensionSection ADirections：For each blank in the following passages 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.This summer we said goodbye to unnecessary plastic waste. Starbucks committed to ___41___ plastic straws in all locations by 2020, IKEA banned all single-use plastics from its stores, and entire cities banned the use of plastic bags and straws. And now we have one more thing to add to our consciousness-raising list: People are starting to understand the ___42___ of contact lenses（隐形眼镜）.According to a new research out of the American Chemical Society, 20 percent of people who wear contact lenses throw them away in the toilet or sink. But as medical ___43___, contact lenses are specifically designed to be resistant in touch environments, and ___44___ they don’t biodegrade easily. Throwing contact lenses into toilet is particularly concerning because their size and ___45___ allow them to slip through filters（过滤器）meant to keep non-biological waste out of wastewater treatment plants.The study found that the chemical and mechanical processing at these treatment facilities were unable to ___46___ break down contact lenses, leaving them as part of the treated water. Post-treatment wastewater is typically spread on fields, where contact lenses can make their way into surface water and cause environmental damage.It may seem like a small thing, but with over 45 million contact ___47___ in the United States, all that plastic adds up. We are talking about 22 tons of contact lenses being improperly thrown away every year here, unnecessarily adding to the hundreds of thousands of tons of microplastics ___48___ in our oceans.So what is the right way to throw away contact lenses?It turns out that properly dealing with contact lenses is pretty ___49___. One option is to throw them in the garbage. While this will keep them out of our water ___50___, it sends them to landfill—which is not really any better. Unfortunately, you can’t just throw your contacts in the recycling bin and call it a day, either. Due to their size and packaging materials, recycling facilities typically cannot ___51___ contact lens processing, so they go to landfills. In order to actually be recycled, contact lenses need to be ___52___ at a specialty recycling facility.This doesn’t mean that all eco-conscious contact-wearers must stick to glasses, though. Fortunately, in an effort to ___53___ the waste produced by contact lenses and facilitate the recycling process, some eye care companies have started their own recycling ___54___. Through these programs, individuals can ship their used contacts to TerraCycle（a company that ___55___ in recycling the hard-to-recycle）for free.41.

2018届杨浦区高三语文期中考试作文范文

2018届杨浦区高三语文期中考试作文范文材料：作文（70分）《论语·子张》中子夏①曰：“虽小道，必有可观者焉。

致远恐泥，是以君子不为也。

”XXX认为虽然小的技能、技艺，也一定有可取之处，但对远大的事业恐有妨碍，所以君子不从事这些小技艺。

当代社会提倡“工匠精神”，希望以极致的态度对待自己的产品，精雕细琢，精益求精，以达到至高的精神境界。

注：①子夏，XXX弟子，XXX之一。

请根据以上材料，自选角度，自拟题目，写一篇文章。

要求：(1)不少于800字。

(2)不要写成诗歌。

(3)不要透露个人相关信息。

学生作文：（共3篇）于细微处为门五，为窗八，细若蚊足，勾画了了。

百年前的一盏核舟，寥寥数寸，却演绎这一方“苏子”与客泛舟的小世界。

当代社会所崇尚的工匠精神，实则世世代代传承于中华民族的血脉之中。

匠人们悉心雕琢，至细至微，如奉敬神灵一般，刻画着自己面前的艺术作品。

就这样，几十年如一日，工匠精神带来的不仅仅是精益求精、尽善尽美的严谨态度，更是从将人灵魂深处燃起的对于文化与美的庄严与崇敬。

然而，这些小的技艺中诞生的产品总是其貌不扬，容易引发来自各界的争议与担忧。

XXX在《论语》中如是评价这种“小道”：虽小道，必有可观者，致远恐泥，是以君子不为也。

他承认这种貌似卑微的技艺有可取之处，却断言这不是君子所追求的终极人生目标，这会妨碍一个人成就伟大事业。

小道，终究是坊间的奇技淫巧.难登大雅之堂。

我并不否认XXX所说，毕竟这些小技巧会对心怀高远胸襟抱负之人的仕途，带来些阻碍。

在礼乐崩坏的春秋战国时代，XXX眼中的君子，无非是匡时济世，竭力维护社会秩序，国家统一的仁人志士。

诚然，在一定程度上，君子之“大志“与匠人之“小道”存在抵忤，不能并存，然而时代风云变化，在当今匠人心中的大志与小道其实并无矛盾，都化为了其实现自身人生价值的目标、传承与发扬文化的内在追求。

工匠肉体，既内化于自身，又使文化繁衍生生不息。

近期在XXX一套播出的“大国工匠”纪录片，有幸让我们在镜头前见识到了这些工匠们的平凡生活，与崇高的追求，个中《我在故官修文物系列》讲述了一位老先生固守岗位数十年，只为修缮那些从这座国家园林中，重见天日的中华文化瑰宝，付与他们在新时代重生的机遇。

The auction will attract many private collectors in Scotland．EHow to enterThe entries will be judged by a panel that includes artist Levi Pinfold - who illustrates the house editions of the Harry Potter books；Emily Drabble from the charity BookTrust；and Anna Bassi，editor-in-chief of The Week Junior．Winners will be announced in The Week Junior issue．One lucky overall winner will receive a huge bundle of Harry Potter prizesy including：You'll be able to step onto authentic sets，discover the magic behind spellbinding special effects and explore the behind-the-scenes secrets of the Harry Potter film series，located at the studios where it all began．*A perosnalised Hogwarts house trunk full of goodies from your chosen house．*A set of the first three Harry Potter novels in hardback in your house livery，illustrated by Levi Pinfold．*A limited-edition print of artwork from the house editions，signed by artist Levi Pinfold．*Harry Potter and the Prisoner of Azkaban hardback illustrated edition signed by Kim Kay．The winner's school will get：*Hardback editions of all seven Harry Potter novels，with cover illustrations by Jonny Duddle．*Hardback illustrated editions of the first three Harry Potter books，illustrated by Jim Kay．*The Tales of Beedle the Bardillustrated edition by Chris Riddell．*A year's subscription to The Week Junior．Runners-up*Nine runners-up will each receive a set of the first three hardback house editions in your Hogwarts house livery．Their school will get a complete set of Harry Potter hardbacks with cover illustrations by Jonny Duddle，and a year's subscription to The Week Junior．22.To enter for the competition，participants must ______ ．A. send the completed form to charity BookTrustB. draw and describe their chosen PatronusC. purchase a complete set of Harry Potter seriesD. agree to subscribe to The Week Junior for a year23.What will the winner's school and the runners-up' schools get？______A.

First prize winner may win an award of up to £350 for accommodation．FGardeners may be able to cut down on the amount ofweeds（杂草）killer they use by dealing with invaders at specific times of the day，such as dawn，a new study suggests．Researchers at the University of Bristol have discovered that the 24-hour rhythms of plants leave them more defenseless to herbicides（除草剂）at different points in their daily 24 hour cycle．They believe the findings could help farmers by reducing crop loss and improving harvests．And gardeners could benefit from knowing which weeds respond better at certain times of the day．In recent years，pesticides and herbicides have been implicated in the decline of important pollinating insects，such as bees．Dr Antony Dodd，senior author of the new study，said："The research suggests that，in future，we might be able to improve the use of some chemicals that are used in agriculture by taking advantage of the biological clock in plants．Just like humans，plants have evolved to take advantage of cycles of night and day，with certain biological processes turning on at different times of the day．Scientists have discovered that many drugs work much better in humans if they are given at specific hours．Aspirin，for example，has doubled the impact on thinning the blood if taken at night as opposed to in the morning．The process is known as ‘chronotherapy' and researchers wanted to find out if the same concept could be applied to plants．Many gardeners already know that plants drink in more water in the morning because their pores（气孔）are open to take advantage of early morning dew and water vapour．At the break of the day，plants are also not busy producing food throughphotosynthesis（光合作用）．The open pores could also be the reasons that chemicals are more effective at dawn and also at dusk．The air is also likely to be stiller at dawn and dusk，meaning that pesticides or herbicides are less likely to be blown away to places where they are not wanted．Pesticide labels often warn against spraying on windy days in case they endanger people or animals．Many insects are active early in the morning and around dusk，also making very early morning and early evening effective times for insecticide．Commenting on the study，Dr．Trevor Dines，Botanical Specialist at the conservation charity Plantlife，said："This is fascinating research which will be of great interest to many gardeners like me．If anything T used to think the opposite was true - that applying herbicides and pesticides late in the day would be better as they'd remain in Vet contact' withthe plant for longer in the cool of the night and therefore be taken up or absorbed more effectively．This research knocks that assumption on its head"25.Which of the following can replace the underlined phrase "implicated in" in the thirdparagraph？______A. restored toB. blamed forC. limited toD. composed of26.According to the research，what are the reasons for using herbicides in the morning？______A. The process of photosynthesis is most active in the morning．B. Insects are more defenseless in the morning than any other time of the day．C. Bigger pores on the plants make herbicides work more effectively．D. The stronger morning wind blows pesticides away to more places．27.What can be inferred from the last paragraph？______A. Gardeners were interested in combining science with gardening．B. A long time had passed before herbicide was applied in farming．C. The old assumption about the use of chemicals proved right．D. Many gardeners used to spray herbicides at the wrong time．28.What is the main idea of this article？______A. New chemicals have been found to help kill harmful insects．B. Biological clock of plants could help gardeners use less weed killer．C. Plants' cycles can be taken advantage of to improve the environment．D. The research on the effects of pesticides has enabled good harvests．Every Little Bit Counts？One of the weapons in the fight against poverty is microcredit also called microlending．Microcredit is the practice of giving very small，short-term loans to poor people．(1) The loans help the borrowers start or upgrade small businesses．Microcredit organizations assume that poor people can lift themselves out of poverty if they only have access to standard financial services．Grameen Bank，started as a project in 1976，is a pioneer of microcredit．(2) Borrowers often have no steady job no other property，and no one to co-sign on the loan - common requirements for getting a loan elsewhere．Grameen Bank promotes credit as a human right，and with a 98% repayment rate，it seems to have helped its borrowers improve their lives and made a profit through interest in the meantime．Successes like Grameen Bank and others caused governments and NGOs to rush to fund microcredit operations．How wonderful to imagine that the cure for poverty could be profitable! However，recent studies question how effective microcredit really is．Critics say that poor people with enoughentrepreneurial（创业的）drive to get a loan would have succeeded anyway．Those without the drive don't end up in better circumstances after paying back loans，which aren't always used for businesses．(3) And though microcredit is described as a way to empower women，some say the loans aren't causing any measurable improvement in women's lives．The ideas behind microcredit are uplifting：that all humans are filled with potentials and that one small bit of assistance can help a whole family live better．(4) Time and close study will tell if microcredit is really the miracle it appears to be．A．They also say that without a basic education，poor borrowers aren't equipped to manage the businesses they create．B．In general，the loans are 100 USD or less，usually paid back within six months．C．Borrowers need to provide the credit history，which the lenders will use as the criteria when evaluating a loan．D．They may，however，ignore systematic causes of large-scale poverty．E．Most microcredit agencies are struggling as the vast majority of loans are not paid back．F．It has given out more than eight billion dollars in loans to people who could never borrow money otherwise．29.

F33.Directions：Read the following passage．Summarize the main idea and the main point（s）of the passage in no more than 60 words．Use your own words as far as possible．Even without ‘assigned' seating，it is a little surprising how many people always choosethe same seat in a classroom or auditorium．Or the same table in a restaurant．Afterclose observation，psychologists believe they have figured out the reason for thisbehavior．In one such study，Marco Costa，a psychologist at the University of Bologna in Italy selected two lecture halls for a sample of 47 and 31 students．Costa purposefully chose rooms where there were more seats than students so that they had more freedom to choose where to sit．He set up hidden cameras to record how the students chose their seats overa period of four weeks．As suspected，most students picked the same scat over andover．But why？Costa calls this habit ''territoriality（领域感）．M The word often makes us think ofgangs protecting their territory or wolf packs（群）fighting off other packs to control a certain area．In other words，territoriality usually suggests aggression anddefense．However，Costa as well as another psychologist，Professor Robert Gifford of the University of Victoria，believes that this seat-choosing behavior is designed tokeep the peace．"Most of the time，most people claim a space and others quietly agree to it，" Gifford explained．The phenomenon of classroom seating selection perhaps shows an even deepertruth．Life can be messy and unpredictable．The reason students go to school is tostudy．Going to class and knowing where you will sit is just one less thing to distract a student from this greater purpose．In short，sitting in the same place sets students up for a psychologically more comfortable learning environment and makes it easier for them to concentrate on the lecture at hand．34.新的路标似乎杜绝了可能发生的交通事故．（seem）______35.七十周年阅兵式壮观的景象将永远铭刻在我的脑海里．（impress）______36.由某些如软塑料或金属等材料制成的容器，不适合用微波炉加热食物，这是常识．（It）______37.不管我们多么强烈地不认同他人观点，尊重其表达的权利和宽容他们的想法是学校应该鼓励和提倡的价值观．（no

Chessmen）遗失的五个棋子之一．阅读理解题测试考生在阅读基础上的逻辑推理能力，要求考生根据文章所述事件的逻辑关系，对未说明的趋势或结局作出合理的推断；或根据作者所阐述的观点理论，对文章未涉及的现象、事例给以解释．考生首先要仔细阅读短文，完整了解信息，准确把握作者观点．22.【答案】【小题1】B【小题2】B【小题3】C【解析】（1）B．细节理解题．根据第一段The entries will be judged by a panel that includes artist Levi Pinfold - who illustrates the hou se editions of the Harry Potter books； Emily Drabble from the charity BookTrust；and Anna Bassi，editor-in-chief of The Week Junior． Winners will be announced in The Week Junior issue．这些作品将由一个小组来评判，其中包括艺术家LeviPinfold-他展示了《哈利•波特》一书的家庭版；来自慈善图书的EmilyDrabble；和AnnaBassi，主编的《少年周刊》．可知参赛者必须画出并描述所选的人物，方可参加比赛；故选B．（2）B．细节理解题．在第三段The winner's school will get中提到Hardback editions of all seven Harry Potter novels，with cover illustrations by Jonny Duddle（所有七部封面插图由乔尼•达德尔制作的哈利波特小说的精装本），而在第四段Runners-up也提到了Their school will get a complete set of Harry Potter hardbacks with cover illustrations by Jonny Duddle（他们的学校将得到一套完整的封面插图由乔尼•达德尔制作的哈利波特精装本）．由此可以推知，B项符合题意．故选B．（3）C．细节理解题．根据第一段可知，比赛的评委是由artist Levi Pinfold （艺术家列维•平福尔）和Anna Bassi，editor-in-chief（主编安娜•巴西）组成，而不是illustrators and editors（插画师和编辑），故排除选项A．第一段最后一句Winners will be announced in The Week Junior issue（获奖者将在《青少年时事新闻》杂志上公布），未提到时间，故排除B项．本文属于说明文阅读，作者通过这篇文章主要向我们描述了参加这一次画出哈利波特系列人物比赛的参赛要求．考察学生的推理判断能力和联系上下文的的能力，在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．此类的填空题一定要联系上下文，根据上下文的内容加上自己的理解，再作出正确的判断25.【答案】【小题1】B【小题2】C【小题3】D【小题4】B【解析】1．B．词义猜测题．根据划线词所在句子In
