My target was to raise ￡2,000, a big challenge. But it was brilliant because collecting not only motivates you to train hard, but also means you’re not just running for yourself. You’re running for something much greater.You’d be surprised at how many people donate money around the time of the marathon. People were so crazy that I hardly noticed how quickly things happened and how quickly the following months flew by. It was my first marathon. I did my research, made a plan and put it up on my wall and crossed an item off every time I went for a run. That’s the key. The training plan lasted 16 weeks. I started with five-mile runs and got myself up to 8-10 miles.Your training pays off on the day of the event. Go over Tower Bridge with thousands of people cheering you on, and run down roads that you never get the opportunity to go to – it’s amazing. It’s like a leap of faith. The truth is that if you never take the risk, you’ll never know how much you’ll push yourself and what you can achieve.I haven’t made a decision whether to take part in next year’s London Marathon. But that’s fine. I know I’ve already achieved something rather special that I can’t stop talking about.24. What is the author’s purpose in joining in the marathon?A. To earn a reputation.B. To challenge a 40 km run.C. To raise awareness of physical exercise.D. To collect money for charity.25. What is the most important in the preparation according to the author?A. The proper training plan.B. The craziness about the marathon.C. The donation around the marathon.D. The gradual change in the running distance.26. What did the author think of the marathon?A. It’s troublesome.B. It’s disordered.C. It’s exhausting.D. It’s inspiring.27. What can we learn from the last paragraph?A. The author has decided to enter for the 2018 London Marathon.B. The author will take part in other marathons all around the world.C. The author regards the marathon experience as one of his proudest.D. The author thinks one marathon is enough for a person to take pride of.CRecycling programs usually give new life to materials like paper, metal, plastic and glass. But a program in the eastern America is recycling shellfish to help the Chesapeake Bay.Oysters(牡蛎) is known to help clean the water. Besides, generation upon generation of oysters form reefs, which provide homes for fish and crabs.Oysters are a tradition in the Chesapeake. They are good for the bay. But environmental damage and too much harvesting have cut the oyster population there.An organization called the Oyster Recovery Partnership started the recycling program earlier this year. Baby oysters need to attach themselves to a shell or other hard surface as they grow. Scientists are using recycled shells as part of an oyster reproduction(繁殖) program. More than 15 restaurants, seafood dealers and other businesses have joined the Oyster Recovery Partnership. Maryland and Virginia are also taking part in the program.One of the restaurants involved is in Washington. Oysters are a specialty at the Old Ebbitt Grill. Its manager Christian Guidi says they serve about 1,500 to 3,000 oysters a day and that obviously does create a lot of shells.But the restaurant no longer throws away all those shells. The Oyster Recovery Partnership takes them away for recycling.First the shells get washed. Then they go to the Center for Environmental Science at the University of Maryland for further processing.The shells are placed in tanks with hundreds of millions of oyster lavae(幼体). In this way, the baby oysters can be raised until they have grown big enough to be moved to the Chesapeake.This year, the Oyster Recovery Partnership helped produce and plant more than 450 million baby oysters in the bay.Don Meritt heads the oyster recovery program at the University of Maryland. He says the goal is not just to increase the oyster population. Their real goal is to try to restore healthy oysters to the Chesapeake Bay so that they can help restore a healthy Chesapeake Bay.28. What causes the number of oysters to drop in the Chesapeake Bay?A. Too much rain.B. Water pollution.B. Hot weather D. Overfishing.29. What did the Old Ebbitt Grill do with the shells in the past?A. It collected all the shells.B. It threw the shells away.C. It sold the shells as waste.D. It poured the shells into the sea.30. Why are shells placed in tanks with oyster larae?A. To help them to grow.B. To provide more nutrition.C. To make the tank like sea.D. To serve as homes for them.31. What can we learn from the text?A. Recycled shells can improve the environment.B. The number of oysters has increased in the bay.C. The oysters are popular in cities like Washington.D. The oyster recovery program needs more support.DHuman beings enjoyed a double treat in January with the appearance of two supermoons. The first one rose onthe night of New Year’s Day. The second came on the last night of the month, topping off with a lunar eclipse(月食). That is the end of trilogy(三部曲) of big moon treats that began on Dec.3, 2017 with a full cold moon. The January.1 supermoon was the biggest of the year. The moon appeared to be oversized for a few nights after that, though it was no longer a full moon.A supermoon is a full moon that appears at the perigee(近地点), the closest point in the moon’s orbit to the Earth, about 14 percent larger and 30 percent brighter than full moons that appear at the apogee, the farthest point in the orbit. Supermoons, hanging around all night, are easy to see and are not damaging the eyes, no matter how long you gaze at the moon.For those still talking about a hangover on the night of Jan.1, an even more charming supermoon rose on the night of Jan. 31. That was the second full moon of the month, which is usually called a ―blue moon‖ because a double full--moon month occurs essentially once in a supermoon — about every two and a half years. A blue moon is even rarer when it’s a supermoon. But that wasn’t the only rarity that night. The super blue moon also occurred during a total lunar eclipse. Because skies were clear, the total eclipse was visible from eastern Asia across the Pacific Ocean to western North America.Lunar eclipses make moons appear blood red because of the way the blocked sunlight bends, when the Earth moves between the sun and the moon, blocking the sun’s light from reflecting the moon. So many people witnessed the super blood moon during the night of the lunar eclipse. To get the full effect of the lunar eclipse, watch at moonset.32. What can we learn about the Jan. 31 supermoon from the text?A. It was a super blue moon.B. It began with a lunar eclipse.C. It was observed all over the world.D. It was the biggest moon of the year.33. What is the second paragraph mainly talking about?A. The supermoon’s origin.B. The supermoon’s definition.C. The supermoon’s function.D. The supermoon’s identity.34. Why does the moon look red during the lunar eclipse?A. Because of the angle of the sunshine.B. Because the sky is filled with dark clouds.C. Because Pacific Ocean reflects the moonlight.D. Because sunlight can’t reach the moon directly.35. Which of the following can be the best title for the text?A. Double New Year Supermoons.B. The definition of a Supermoon.C. Supermoons with a Lunar Eclipse.D. The Rarity of the Blue Supermoon.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。

Transferring money from your account to others'is a complex process．B. It's easy for you to tell bank robbers from other coffee drinkers．C. Online thieves could steal money because people pay little attention on the networksecurity．D. All the networks available in a coffee shop are illegal．30.What's the author's attitude towards Wi-Fi traps？______A. Positive．B. Negative．C. Objective．D. Indifferent．31.What's the best title of this passage？______A. Be cautiousabout free Wi-Fi networks．B. The thief who withdraws our money．C. The convenience of free Wi-Fi networks．D. The process of stealing money．【答案】【小题1】A 【小题2】C 【小题3】C 【小题4】A【解析】28．A 词意猜测题．根据第二段的句子Transferring money from your account to others'accounts．把钱从你的账户转到别人的账户上可知get on top of 的意思应该与deal with 意思相符，所以答案选A．29．C 细节理解题．根据第六段句子They rely on the fact that most of us are not careful about the security of networks we connect to．他们依赖这样一个事实，即我们大多数人对我们所连接的网络的安全性并不十分谨慎．所以答案选C．30．C 态度判断题．根据全文内容可知，作者只是在客观地描述免费WI-Fi，所以答案是objective"客观的"．所以答案选C．31．A 标题判断题．本文作者主要描述的是免费WiFi的陷阱，详细的描述了免费WiFi 是如何让人进入陷阱上当受骗的，所以意在警告人们对于免费的WiFi一定要谨慎．所以答案选A．在科技飞速反展的今天，利用高科技犯罪的事件层出不穷．本文提到的是WiFi陷阱值得注意．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．DA current topic of debate is the amount of support and services we are willing to provide for disabled people．Many people believe that society has become more caring over the old．However，if we look back in time，this may not prove to be true．A good example can be found by looking at some remains（遗骸）of a prehistoric culture．Several skeletons（骨架）were found in the Shanidar Cave in Iraq．It was the home of a tribe （部落）of Neanderthals who existed more than 40 000 years ago．One of these skeletons was a man about 40years old，an old age for that period．He is thought to have been killed by a falling stone．Careful study of the bones has shown that the man's right arm had never fully developed and had been cut off below the elbow（肘）．The condition of the teeth was also unlike that of other Neanderthal men's．They showed signs of excessive（过多）use，as if they had been used to make up for the lack of a right arm．How could someone so disabled from his earliest years have survived to become an adult，and even live on to old age？Societies in such early times faced severe conditions．People who could hunt for meat were few．A disabled person must have needed to keep close to the cave and been provided with meat．In fact，more care were shown towards this disabled man during that time，which suggests that the ancient people did better in caring their disabled people than we do in present-day societies．Such concern indicates a sense of unity（团结）and cooperation that made possible the future achievements of humanity．With this in mind，are we doing enough for the disabled？Rather than being too proud of the efforts that modern society has made，it would be wise to consider if we even equal the efforts of the old societies．32.Considering the remains of this prehistoric culture makes us ______

陕西省西安中学高二历史下学期期中试题(平行班,含解析)
西安中学2017—2018学年度第二学期期中考试高二历史试题（时间：90分钟；满分：100分）一、单选题（本大题共30小题，共60分）1.学者徐增阳说：“在农民的心目中，理想的国家政治关系成了家族关系的自然放大，官吏被称为‘父母官’，理想的皇帝就是‘爱民如子’的慈父。
”这主要体现了传统中国：A. 家族血缘关系B. 中央集权意识C. 家国同构观念D. 安土重迁理念【答案】C【解析】【详解】由农民心中“国家政治关系成了家族关系的自然放大”、“父母官”、“君父”等说法，可知这里讲的是中国古代家国同构的观念，C项正确；材料中家与国是联系在一起，A项不符合题意；题干中没有分析中央对地方管理，B项错误；安土重迁强调的是乡土意识，D项不符合题意。
2.许多学者认为，秦朝的建立标志着官僚政治取代过去的贵族政治。
根据所学知识判断，“官僚政治”的最基本特点应该是A. 颁布《秦律》，依法治国B. 官员由皇帝直接任免C. 丞相掌握大权D. 建立从中央到地方的行政系统【答案】B【解析】试题分析：考查秦朝的郡县制度。
秦朝建立后，废分封，行郡县，官员不再世袭，没有封土，把地方官员的任免权收归了中央，故B正确。
AC项不是从官员的任命方式上进行分析的；D 项只是说秦朝建立了专制主义中央集权制度，也未体现官吏的选拔方式。
因此ACD均错误。
考点：古代中国的政治制度·秦朝中央集权制度的形成·专制主义中央集权制度的确立。
3.“自世卿贵族门阀举荐制度推翻，唐宋厉行考试，明清峻法执行，无论试诗赋、策论、八股文，人才辈出；虽所试科目不合时用，制度则昭若日月。
”引文意在强调科举制A. 选拔人才存在缺陷B. 脱离现实，学不致用C. 考试内容规范合理D. 制度具有公正合理性【答案】D【解析】【详解】从题干中“人才辈出，虽所试科目不合时用，制度则昭若日月”的信息可以看出，材料认为科举制虽有弊端，但还是培养了大量人才，具有公正合理性，故D 项符合题意；材料讲“所试科目不合时用”但“制度则昭若日月”，其强调的是科举制的积极作用，故A 错误；材料强调的是科举制培养了人才，B 不是其强调的重点，故B 错误；材料未体现科举考试内容规范合理，故C 错误。

“中庸”辨义“中庸”是儒家伦理学说的一个核心思想，但在现实生活中却常常被误解和误用，颇有辨析的必要。
在有的人看来，所谓“中庸”，就是做人要圆融，善于“和稀泥”、当“老好人”；做事要平庸，不出头、不冒尖、守“本分”，满足于随大流、跟着走。
这种观点不仅违背了儒家关于“中庸”的原意，而且在一定程度上误导了人们对儒家伦理学说的整体认识和评价。
事实上，这种是非不明、善恶不分、庸碌无为的“老好人”、“本分人”并非儒家所尊崇的“中庸”之人，而是其所贬斥的“乡愿”，这种人格与品行也是儒家所极力反对的。
对“中庸”的误解，除了少数人是刻意而为、混淆视听之外，大多数人是出于对“中”、“庸”二字的望文生义：将“中”理解为“走中间路线”，将“庸”理解为“平庸”。
这种理解并不符合儒家尤其是先秦儒家的本意。
我们来看看相关文献中的解释。
在《中庸》一书中，“中”与“和”是放在一起表述的，二者密切联系、不可分割，正所谓“喜怒哀乐之未发，谓之中；发而皆中节，谓之和”。
由此可以看出，“中”在这里是一个时间概念而非距离概念，是所谓“时中”，即在合适的时机做合适的事、表达合适的情感，而不是折中调和或不分场合地率性而为。
关于“庸”，汉代学者郑玄的注释是：“中庸者，以其记中和之为用也；庸，用也。
”也就是说，儒家所谓“庸”，就是人伦日用；所谓“中庸”，就是在日常生活中运用“中和”的理念，追求言行在时机、氛围等方面的恰如其分，不失礼、不失态、不偏激。
“中庸”或“中和”的理念还可以超越人伦的领域，运用到人与自然关系上：人们通过对自然界万物生长与四时变化规律的领悟和顺应，能够“赞天地之化育”，达到“天人合一”的境界。
这就是《中庸》中所说的“政中和，天地位焉，万物育焉”。
儒家认为，在人伦日用中做到“中庸”，即行所当行、止所当止，是一个极高的境界，需要“究天人之际、通古今之变”——对自然、社会和人生的运行规律、运行法则有深刻的体验和把握。
