A
One day, a college student was taking a walk with a professor. As they went along, they saw lying in the path a pair of old shoes. They supposed the shoes belonged to a poor man who was employed in a field close by, and who had nearly finished his day’s work.
The student turned to the professor, saying, “Let us play the man a trick: we will hide his shoes, and hide ourselves behind those bushes, and wait to see his confusion when he cannot find them.”
“My young friend,” answered the professor, “we should never amuse ourselves at the expense of the poor. But you are rich, and may give yourself a much greater pleasure by tricking on the poor man. Put a coin into each shoe, and then we will hide ourselves and watch how the discovery affects him. ”
The student did so, and they both placed themselves behind the bushes close by. The poor man soon finished his work, and came across the field to the path where he had left his coat and shoes. While putting on his coat he slipped his foot into one of his shoes, but feeling something hard, he bent down to feel what it was, and found the coin. Astonishment and wonder were seen on his face.
He fixed his eyes on the coin, turned it round, and looked at it again and again. He then looked around him on all sides, but no person was to be seen. He now put the money into his pocket, and continued to put on the other shoe; but his surprise was doubled on finding the other coin. His feelings overcame him. He fell upon his knees, looked up to heaven and cried a sincere thanksgiving, in which he spoke of his wife, sick and helpless, and his children without bread, whom the timely help, from some unknown hand, would save from dying.
The student s tood there, deeply affected, and his eyes filled with tears. “Now,” said the professor, “are you no t much better pleased than if you had played your intended trick?”
The youth replied, “You have taught me a lesson which I will never forget.”

Tips for Cycle Trips
Cycling has many advantages as a form of travel, as it is the fastest way to travel by human power, and slow enough to allow the type of local involvement that is impossible with powered travel. Cycle travel is also a cheap form of transportation.
Distance
On level terrain（地形）, without a headwind, a cyclist of average fitness on a touring bike can comfortably cover 60–120km a day. Distances of up to 250km a day are possible, but anything much beyond 120km will require considerable physical tension and not allow many stops to enjoy the places you visit. For many, 80–100km a day will be the most suitable distance to aim for, as it will give a sense of achievement and also leave plenty of time for meals and activities.
Geography
The gradient（坡度）of the trip will reduce your range. A basic rule is that for every 100 metres of altitude you climb, you should add an extra 15 minutes to your journey time. In hilly or mountainous areas, the easiest routes for cycling are downstream along major rivers, as overall they will be downhill. A long, roundabout route along a river will usually be easier than a short, direct route over a hill or mountain pass. However, it is worth bearing in mind that the most scenic routes often come from hilly terrain.
Eat
Food choice depends largely on where you are, so see the respective sections for more information about foods. As you will be working hard, it's important to get enough energy in your food. On long trips away from major towns there may be little quality food available, so be prepared to live on candy bars, prepared meat products and the like if the need arises.
Sleep
While you can take a tent with you, many hotels and especially campsites can accommodate cyclists. However, there are also some hotels that may be less used to accommodating cyclists. If you are exploring an unfamiliar world, asking about the accommodation spares you the search for a new place to stay after a long exhausting day of travel.

61. From the passage, we can learn that ________.
A. high quality food is easy to get on long trips
B. hotels seldom provide accommodation for cyclists
C. cycling over a mountain is challenging but worthy
D. it takes cyclists 15 minutes to climb 100m of altitude
62. We can probably read this passage in .

Time Travel
If you could travel in time, where would you go? Perhaps you would watch
an original performance of a Shakespeare’s play in Elizabethan England? What
about hanging out with Laozi in the Spring and Autumn Period? Or maybe
you'd voyage far ahead of the present day to see what the future holds.
The possibility of time travel is indeed appealing . Stories exploring the
subject have been around for hundreds of years. Perhaps the best known
example is science fiction novel The Time Machine , which was written by H.G .
Wells and published in 1895 for the first time. It was adapted into at least two
feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term "time machine", coined by Wells, is now universally used to refer to a vehicle transporting people into the far future. But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called “wormholes”, which could be used as shortcuts to other periods. Einstein’s theory of relativity allows time travel in extreme circumstances. And British physicist Stephen Hawking says you could travel into the future with a really fast spaceship —going at nearly the speed of light. Though building such a spaceship would of course be no simple task. Even if you could travel into the past, there is something called the “grandfather paradox ”. It asks what would happen if a time traveler were to go back in time and have his own grandfather killed for some r eason, and therefore prevent himself from being born. If the time traveler wasn’t born, how would he travel back in time?
And would you really like to visit the future? In H.G . Wells’ book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30

million years into the future where the only living thing is a black object with tentacles(触角).
If that’s what’s in store, maybe we are better just living in the present day after all.
63. The novel The Time Machine mentioned in Paragraph 2 aims to show ______.
A. people’s interest in time travel
B. the special feature of the book
C. the long history of time travel
D. the contribution of H.G. Wells
64. Einstein’s and Hawking’s theories _____.
A.have similarities in many ways
B.push the invention of the first spaceship
C.have proved wrong by some time travelers
D.suggest the possibility to invent the time machine
65. In Paragraph 4, “grandfather paradox” probably refers to the idea that ______.
A.the traveler is prevented from meeting his grandfather
B.the traveler goes back in time to seek for his grandfather
C.the grandfather’s death makes the traveler’s birth impossible
D.the reunion of the traveler and his grandfather brings happiness
66. According to the passage, what is probably the author’s attitude towards time travel?
A. Unclear.
B. Skeptical.
C. Supportive.
D. Unconcerned.

Speed-reading is a necessary skill in the Internet age. We skim over articles, e-mails and WeChat to try to grasp key words and the essential meaning of a certain text. Surrounded with information from our electronic devices, it would be impossible to cope if we read word by word, line by line. But a new trend calls on people to unplug and enjoy reading slowly, listing benefits beyond the intelligent stimulation.
A recent story from The Wall Street Journal reported on a book club in Wellington, New Zealand, where members meet in a cafe and turn off their smartphones. They sink into cozy chairs and read in silence for an hour. Unlike traditional book clubs, the point of the slow reading c lub isn’t exchanging ideas about a certain book, but to get away from electronic devices and read in a quiet, relaxed environment. According to the Journal, the Wellington book club is just one example of a movement started by book lovers who miss the old-fashioned way of reading before the Internet and smartphones.
Slow readers, such as The Atlantic’s Maura Kelly, say a regular reading habit sharpens the mind, improves concentration, reduces stress levels and deepens the ability to sympathize. Another study published last year in Science showed that reading novels helps people understand others’ mental states and beliefs, a fundamental skill in building relationships.
Yet technology has made us less attentive readers. Screens have changed our reading patterns from the straight, left-to-right sequence to a wild skimming and skipping pattern as we hunt for 只供学习与交流

The Internet may have made us stupider, says Patrick Kingsley from The Guardian . Because of the Internet, he says, we have become very good at collecting a wide range of interesting news, but we are also gradually forgetting how to sit back, reflect, and relate all these facts to each other.
Slow reading means a return to an uninterrupted, straight pattern, in a quiet environment free of
distractions. Aim for 30 minutes a day, advises Kelly from The Atlantic .
“You can squeeze in that half hour pretty easily if only during your free
moments, you pick up a meaningful work of literature,” Kelly said.
“Reach for your e -reader, if you like. Kindles make books like War and
Peace le ss heavy, not less substantive, and also ensure you’ll never lose
your place.”
67. The book club in Wellington mentioned in Paragraph2 shows_________.
A. the new trend of slow reading
B. the decline of electronic devices
C. the importance of exchanging ideas
D. the increasing number of club readers
68. According to Patrick Kingsley, people are stupider partly because of _________.
A. a non-stop reading pattern
B. the straight, left-to-right screen
C. a wide range of tidbits
D. the lack of reflection
69. According to the passage, slow reading _________.
A. contributes to understanding among people
B. promotes the current technology advances
C. provides people with a quiet environment
D. cures the memory loss of elderly people
70. What is the best title for the passage?
A. Benefit of Reading Clubs.
B. Return of Slow Reading.

Attraction of the Minions
When it comes to film, people usually favor good over evil, focus on the hero and ignore the supporting characters. 71
Originally comedic background characters in the film Despicable Me （卑鄙的我），these yellow pill-shaped nuts have totally stolen the show and turned into a popular figure.
This summer the characters debuted （首演）in their own self-titled movie in theaters abroad, having the second biggest opening weekend of all time for a cartoon film according to USA Today . Recently McDonald’s has been including Minion toys with kids’ meals in some areas, causing loyal fans to flock to the restaurant to collect them all. 72

All the houses are painted white and the skies are clear. It's not surprising that the life here is very relaxing, and it is also home to plenty of cafes and art galleries. Wengen in Switzerland Do you ever wonder how the world was before cars were invented? The village called Wengen might just help you realize your dreams. Cars have been banned from this area for close to 100 years, and everything looks like it was taken right out of Heidi. The locals have kept their Swiss culture undamaged. Shirakawa-go in Japan This village is certainly known for its unusual houses with triangular roofs which seem to resemble hands joined in prayer. It's designed to keep snow from piling up on top of houses. These houses are the symbol of the area but there aren't many of them left anymore. Eze in France France in itself is pretty, but its most attractive village is Eze. This community seems to be frozen in time. This village is the perfect melting pot of cultures because of its closeness to Nice. During the Middle Ages, it was desired by invaders(侵略者),and while this was a cause of sadness for the local people in the past, today the village enjoys its rich heritage(遗产).The architecture here is so diverse.

初三上学期期中考试化学的质量分析 初三上学期期中考试化学的质量分析范文 一、命题原则及对试卷的总体评价 1、命题原则 2、试卷构成及难度比 本次化学试卷共设选择题、填空题、解答题、实验题和计算题五种题型，难、中、易比例大约为8:1.5:0.5. 3、试卷的总体评价 试卷突出基础性、加强探究性、体现时代性、应用性、开放性、渗透教育性；其题量适中，结构科学、合理、难易程度基本适当；试卷有利于引导和促进化学教学全面落实“课程标准”所设立的课程目标，有利于更新教师的课堂教学理念、改进教师的教学行为，有利于改善学生的化学学习方式、丰富学生的化学学习体验、提高学生学习化学的兴趣和效率，同时具有诊断、激励、导向、评价、反馈和调控的功能，为教师下一步有针对性的教学，查缺补陋，强化薄弱环节，弥补不足，进行教学反思，提供了依据，也为学生巩固以学知识有目标的进行下一步学习起到积极的作用。 二、学生答卷情况分析 1、全年级成绩统计： 人数平均分及格率优秀率最高分最低分 42967.2271.09％30.65％96.516 2、各题得分率统计： 选择题填空题解答题实验题计算题
得分率62.7％55.3％71.9％58.9％42.3％ 三、考试中反映出的主要问题 本次考试整套试卷看起来并不难，但学生要想做得全对也并不容易，通过分析说明了有以一下几方面的问题： （1）学生基本功还不够扎实。学生对所学知识灵活应用较差， 抓不住本质，化学知识铺垫及其不够。 （2）读图、读表、读题分析能力差，基本概念不清，容易混淆，迁移能力差、探究能力差、学习习惯差。 （3）基础知识掌握不好，少数同学基础知识和基本技能不过关，说明平时训练力度不够。 （4）能力与方法问题。综合性强的试题、联系实际的试题、信 息迁移题、开放性试题、主观题的得分率较低。答题不准确，不严密、不完整、不全面。除了双基存在问题外，主要原因是：阅读理解、综合分析、自学迁移、语言表达、科学探究等能力较差，对化 学学科中常用的科学方法很不熟悉。 四、教学建议 1、继续深化对新教材的研究 在总结以往对新、旧教材研究基础上，还要注意教学中要以教材上的双基为载体，重点指导学生学习化学的基本方法，培养学习兴 趣和好习惯，特别要关心和帮助学习困难的学生，使他们树立学习 自信心，达到新课程标准规定的基本要求。 2、加强深入对新教学方法的研究 要不断更新教学观念，教学要恰当采用自主学习、合作学习、探究学习等充分发挥学生主体性的各种教学模式，优化教学过程，引 导学生生动活泼地学习，提高教学效率。要创设合适的情境，充分 发扬民主，让每个学生自己思考、自己发现、自己归纳、自己表达，体验探究过程，学习科学方法，训练表达能力，在主动探求知识的 过程中培养各种品质和能力。

When I was a baby I would stand in my wooden crib(婴儿床) and watch the world go by through the window. Some neighbors watched me watching the world go by with by big, wondering eyes and found me very interesting. They used to call me “the beauty at the window”. The early neighbors I could remember were from the second house I lived in. Peter and Paul were twins. We went to play school together although they were a year older than me. I well remember the Alsatian they had which ran into me when I was invited to their fifth birthday party. Needless to say, I was well-known for my loud screams after the party. But they said the pet was scared of my screams and didn’t appear until the party was over. Peter and Paul were the first boys who encouraged me to climb the gate. I could never tell the difference between boy and girl behaviors—I just did what I thought was fun. Not only did I have a great time performing that first climb, I also got my skirts dirty, and was criticized by my mother. The Japanese neighbors I had living in this same house were my favorite, as they introduced me to sea-salt baked shrimps (烤虾) which were so crisp that you could eat the shrimp totally. They gave me some seaweed for my birthday. Thankfully, no other member in my family enjoyed the seaweed as I did. Perhaps what my mother used to joke to me was true, that I was picked up out of the dustbin that belonged to a Japanese home. Maybe sometimes it is difficult to find good neighbors in this society. But all it takes is a spark(火花) to get a fire going. I have decided to be that spark wherever I live and pass love on to my neighbors. 21. We can guess "the Alsatian" in the twin brothers' home is ___________. A. a small child B. an interesting toy C. a dog D. a bicycle 22. From the passage we can know that the author___________. A. enjoyed the Japanese neighbors' cooking style most B. had difficulty getting on with the twin brothers' family C. was described as interesting when playing with boys D. had many neighbors that worked in restaurants 23. What can we infer from the passage? A. The author often moved to other places. B. Peter and Paul liked to play tricks on others. C. The neighbors the author had were good at cooking. D.

2020年北京市海淀区高三期中语文试卷 一、本大题共5小题，共17分。 阅读下面的材料，完成1－5题。 材料一 随着我国居民精神文化消费比重的显著提高，人们开始追求个性化、差异化的商品，关注其蕴含的精神内涵。在互联网技术的助推下，信息交流、品牌文化传播等不断增强，许多基于中华优秀传统文化开发设计的文创产品呈热销态势，由此带动了文创产业的持续发展。在这一热潮中，也存在产品开发同质化、定位模糊、质量不高等问题。那么，如何通过文创产品使优秀传统文化焕发生机，成为滋养当代人生活的养分呢？ 文创产品研发的重心应是实现从文化遗产到文化资源的转化，而文化遗产转化为文化资源，关键之处在于对文化精神的创新表达。从传统造物的形状、色彩、纹饰中提取元素，把它凝练为直观鲜明的文化艺术符号，形成具有中国特色的文创产品，是较为常用的设计方式。比如故宫文创的口红，膏体颜色取自故宫院藏国宝器物，外观取自宫廷绣裳纹饰；敦煌文创的胸章，选用六合莲花等盛唐时期的藻井纹饰。文创产品的创新设计，不仅，而且。比如有的文创产品围绕二十四节气发挥创意，表现人与自然、物候之间的联系；有的文创产品运用“图必有意，意必吉祥”的造型语言，表现中国人追求美好生活、积极向上的态度；有的文创产品展现中华悠久历史文化，表现中华文明海纳百川的广阔胸襟。 中华文化保存在典籍文献、遗址文物中，更蕴藏在人们衣食住行用的日常生活里。文化传统只有存续在生活中，才能不断焕发生机与活力。过去，不少文博场馆的纪念品远离生活，缺乏创意。消费者买来后，大多将其置于角落，任其蒙尘。当下，一系列文创产品从日常生活需要出发进行创意设计：小到胶带、便笺、行李牌，大到公共空间的装饰品；古典的如古器复刻，新颖的有数码周边；时令性的如春茶、月饼、夏季的遮阳帽、冬天的披肩。文创产品设计正打破固化认知，不再局限于礼品馈赠和纪念品收藏，而是深度融入人们的生活。 生活是文创产品创新的广阔天地。为此，设计者当体察生活，深入理解文化内涵，在设计中充分考虑应用场景和实用功能，以“运用之妙，存乎一心”的艺术创造，优化文创产品的使用体验和情感体验，赋予其独特性和生命力，让人们在“日用而不觉”中受到中华优秀传统文化的熏陶，获得丰富的精神启迪，从而更好地传承民族文化。 （取材于般波的相关文章）1．请在材料一的横线处分别填写一个10字以内的语句，使上下文语意连贯。（2分）2．根据材料一，下列说法不正确 ．．．的一项是（3分） A．追求个性化、差异化的商品，反映出人们对精神文化消费越来越重视。 B．文创产业持续发展使基于优秀传统文化开发设计的文创产品开始热销。 C．文化精神的创新表达能够促进文创研发从文化遗产到文化资源的转化。 D．要使文创产品拥有生命力，设计者应当体察生活，深入理解文化内涵。 材料二 北京故宫有180多万件（套）藏品，但并不是所有藏品都能成为文创构思的源泉。选取哪些文物作为文创素材，要考虑其主题是否喜闻乐见，色彩构图是否便于呈现等，
