ATOUR DETAILSWindsor CastleTime-honored in history, Windsor Castle is proudly located on a wooded hilloverlooking the Thames River. Dating back to Norman times, it is famous for sweeping landscaped gardens, which is easy to see why it’s the Queen’s favorite week place. Famous for its architecture and Royal palace, the Castle was built in the 11th century after the Norman invasion. It’s home to priceless artworks and you can visit Queen Mary’s Dolls’ House. Remember don’t miss the ceremony—Changing of the Guards.StonehengeStonehenge is located in the county of Wiltshire. This is your chance to see a side of the world-famous stones that most people don’t get a chance to see! Y ou will never forget your first glimpse of grand Stonehenge with its rocks rising up against the skyline on Salisbury Plain. There are many unsolved mysteries about the rocks. Was Stonehenge intended as a religious temple? A clock for astronomy? A burial ground? Make up your own mind as you explore this unique site that has confused the world for 5, 000 years.BathBeautiful Bath was the first city in England to be added to the UNESCO World Heritage List. No tour of Bath would be complete with a visit to the famous Roman Baths that gave the city its name. This beautifully preserved bathing site still has flowing water from Brain’s only hot spring. Y ou will be amazed by the impressive torch-lighting ceremony as dusk falls. Y ou can also have a taste of Bath’s water in Pump Room, where hot waters are drawn for drinking.21. If your family (2 adults and 2 children) want to visit Winsor, Bath and Stonehenge, it will cost you at least ________.A.￡188B.￡356C.￡168D.￡34622. Where can visitors see Changing of the Guards?A. In WinsorCastle.B. In Bath.C. In Stonehenge.D. In Pump Room.23. Where is the passage probably taken from?A. a science fiction novelB. a travelling brochureC. a news reportD. a sports magazineBWhen I graduated from high school, I wanted to major in comparative literature. But, once I found out my friends were going into “real” majors, like marketing, nursing, and engineering, I figured I needed to do the same to ensure a good career. So I changed my mind and chose Business Management as my major. I forced myself to believe that I would enjoy it and succeed in the future, but eventually I exhausted myself understanding the economy and trying new marketing techniques. Coming o ut of this experience, I realize it is ok to be different from others and to study things like art history and other majors offered in the College of Humanities（人文学科）!The worries most people have about a Humanities degree and finding a career afterwards are that the majors are too abstract, and one will not obtain any applicableskills. Actually ideas discussed in Humanities classes, which are occasionally different from what people commonly believe, offer a broad perspective（视角）. How could one effectively be an unbiased（无偏见的）writer with only a knowledge of the popular opinion of society? How could one speak persuasively with closed minds? Only seeing the world through a single perspective leads to missed learning, missed friendships, and missed growth! Wi th a broader perspective, we’ll be freer, more open-minded, and less limited in what we can become!STEM (science, technology, engineering, and mathematics) graduates learn actual skills in their studies, while humanities majors learn “soft skills” like communicating effectively through writing critically and speaking persuasively, synthesizing（综合）ideas through gathering and interpreting information, and developing cultural awareness. Do those soft skills sound useless and inapplicable to you? Think of it. How often do you communicate with others? Produce ideas? Encounter people from other cultures? Every day. Every SECOND of every day. So why not master these skills?If you choose a major in the College of Humanities, you will be needed. The job market is quietly creating thousands of openings a week for people who can bring a humanist’s grace to our rapidly evolving high-tech future. Y our skills will be valuable to any workplace you hope to be in. Chase after your dream major with all your energy, no matter what other people think.24. Why did the author choose Business Management as his major at first?A. He was tired of learning comparative literature.B. He came to enjoy learning marketing techniques.C. He wanted to go to the same university as his friends.D. He believed Business Management was more practical.25. According to the author, what is a possible way to gain a broad perspective?A. Making more friends and learning from them.B. Exchanging ideas in a philosophy class.C. Opening your mind to future possibilities.D. Getting to know the popular opinion of society.26. In which of the following situations do soft skills play the most important role?A. Writing a software program.B. Performing a heart operation.C. Playing a musical instrument.D. Negotiating with a business partner.27. What could be the best title for the passage?A. Stick to Y our Desired majorB. Broaden Y our PerspectiveC. How to Acquire Soft SkillsD. Humanities vs. STEMCA small school in rural India is gaining attention over the fact that all 300 students are ambidextrous(左右手都灵巧的). Data shows that only one percent of the global population is ambidextrous, but the ambitious founder of V eena V andini School, in Madhya Pradesh, is aiming to change that, starting at a local level.A former soldier and V eena V andini School founder VP Sharma stated that he was inspired to focus on ambidexterity training by India’s first president Rajendra Prasad who was in office from 1950 to 1962. Unexpectedly, the president was ambidextrous. "I read in a magazine that Dr. Rajendra Prasad, India’s first president, used to write with both hands. This inspired me to give it a try, “Mr. Sharma said.”Later when I launched my school at my native village, I tried training the students. ""We begin training students from standard Ⅰ and by the time they reach standard Ⅲ, they are comfortable writing with both the hands,” Sharma added. "Students of up to standard Ⅶ can write with speed and accuracy. Further, they can write two scripts at the same time, one with each hand. Students also know several languages, including Urdu. "Every 45-minute class at V eena V andini includes 15 minutes devoted to handwriting practice, ensuring that every student develops the ability to write with both hands. VP Sharma also believes that the skill better enables students to learn multiple languages, and has them practice writing the same words in different languages at the same time. Although it is widely believed to help increase concentration, more recent studies have found that this is false and studying to become ambidextrous can, in fact, harm cognitive development.A Scientific American study revealed that ambidextrous children performed worse than left- or right-handers on a range of skills, especially in math, memory, and logical reasoning. A study in northern Finland indicated that children who are ambidextrous are much likelier to develop mental health issues, including ADHD, language problems, and academic problems.28.What is special about V eena V andini School?A.It only accepts 300 students yearly.B.It was set up by India’s first president.C.It mainly teaches how to write with both hands.D.It requires students to learn practical living skills29.In which standard can students write quickly and accurately?A. Standard Ⅲ.B. Standard Ⅳ.C. Standard Ⅵ.D. Standard Ⅶ.30.What might most people think of the skill promoted by VP Sharma?A.It helps students fix their attention.B.It does harm to students’ creativity.C.It increases students’ academic stress.D.It inspires students to learn more languages.31.What do the two studies suggest in the last paragraph?A.Kids are reluctant to write with both hands.B.Kids shouldn’t learn to write with both hands.C.Kids who are ambidextrous always fail in the math test.D.Kids who are ambidextrous often have serious mental illnessDEssentially, everyone has two ages: a chronological（按时间计算的）age, how old the calendar says you are, and a biological age, basically the age at which your body functions as it compares to average fitness or health levels.“Chronological age isn’t how old we really are. It’s merely a number,” said Professor David Sinclair at Harvard University. “It is biological age that determines our health and ultimately our lifespan. We all age biologically at different rates according to our genes, what we eat, how much we exercise, and what environment we live in. Biological age is the number of candles we really should be blowing out. In the future, with advances in our ability to control biological age, we may have even fewer candles on our birthday cake than the previous one.”To calculate biological age, Professor Levine at Y ale University identified nine biomarker（生物标志）that seemed to be the most influential on lifespan by a simple blood test. The numbers of those markers, such as blood sugar and immune（免疫的）measures, can be put into the computer, and the algorithm（算式;算法）does the rest.Perhaps what’s most important here is that these measures can be changed. Doctors can take this information and help patients make changes to lifestyle, and hopefully take steps to improve their biological conditions. “I think the most exciting thing about this research is that these things aren’t set in stone,” Levine said. “People can be given the information earl ier and take steps to improve their health before it’s too late.”Levine even entered her own numbers into the algorithm. She was surprised by the results. “I always considered myself a very healthy person. I’m physically active;I eat what I consider a fairly healthy diet. But I did not find my results to be as good as I had hoped they would be. It was a wake-up call,” she said.Levine is working with a group to provide access to the algorithm online so that anyone can calculate their biological age, identify potential risks and take steps to improve their own health in the long run. “No one wants to live an extremely long life with a lot of chronic（慢性的）diseases,” Levine said. “By delaying the development of mental and physical functioning problems, people can still be engaged in society in their senior years. That is the ideal we should be pursuing.”32. Biological age depends on _______.A. whether we can adapt ourselves to the environmentB. how well our body works compared with our peers’C. when we start to take outdoor exerciseD. what the calendar says about our age33. By saying “we may have even fewer candles on our birthday cake than the previous one” in Para. 2, the author means _______.A. we don’t have to celebrate our birthday every yearB. we are chronologically older than last yearC. we might be less happy than the previous yearD. we may be biologically younger than the year before34. What does the author want to tell us by Levine’s example in Para. 5?A. It is necessary to change our diet regularly.B. The test results may give us wrong information.C. Waking up early in the morning is good for our fitness.D. The algorithm can reveal our potential health problems.35. The eventual goal of Levine’s research is to ______.A. free people from chronic diseasesB. work out a solution to genetic problemsC. keep people socially active even in old ageD. provide people with access to scientific theory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。
广东省佛山市第一中学、珠海市第一中学、金山中学2018_2019学年高一语文下学期期中试题(含解析)
广东省佛山市第一中学、珠海市第一中学、金山中学2018-2019学年高一语文下学期期中试题（含解析）一、现代文阅读论述类文本阅读阅读下面的文字，完成下列小题。
文字创造的过程，是把对外间世界的体认，通过民族共同的心理基础转换成表意符号的过程。
中国人由事物外形到意义转借的实践证得的思维方式，于《说文解字》的“六书”法表现得非常切实。
因而在中国，语义学问题隐含着世界观和思维方式的成分。
中国式的语义学不仅限于从哲学、逻辑学的角度解释语言符号间的意义关联。
它实质上牵连着和综合着文字学和语源学的诸多要素，而且通过文字训诂和语源梳理来透视字和词的意义生成、确认和变异，从而使语义分析与文化精神史发生深刻的因缘。
比如，当我们谈论叙事结构，在《说文解字》中发现“结，缔也”，也就是把绳子打成纽结；“构，盖也”，也就是把木材交错架设成屋，“结构”一词的动词性也就跃然纸上了。
谈论中国人对叙事结构的把握，是不能忽视这个词语的动词性，以及动词性所包含的生命投入和生命体验的。
因此我们在思考西方论者把结构视为“多重秩序”、视为“分解——编配”之时，就会从中国结构的动词性及其包含的生命体验的角度，进行质疑和体系的重构了。
返回原点不是为了把自己封闭起来，而是为了在一个坚实的文化根本点上，组织新的思路，走向新的具有现代中国特色的理论体系。
在这番返回和走向的曲折路程中，必然要参照世界人类的现代智慧，参照起步较早的西方现代叙事理论的新进展。
因此建立中国叙事学思路的关键的另一步，就是“参照”。
参照应该伴随着我们思维的全过程，但不能代替我们的思维过程。
参照是创造的催化剂，但不是创造本身。
当我们为了参照而去了解西方信息，并且找出其中的关键所在的时候，眼光就应该停留在这个关键点上，在这里以“中国眼光”与“西方眼光”进行相互注视、交流和质询，考察中西异同，反省异同的原因，清理各自的历史线索，把握其间的文化密码。
文化对行原理在这里是运用得非常活跃的，这种“关键点上的眼光对视”，将会使我们在中西对话中拓展学术视野，形成自身的学术体系。

2、有丝分裂和减数分裂的比较：比较项目有丝分裂减数分裂染色体复制间期减I前的间期同源染色体的行为联会与四分体无同源染色体联会现象、不形成四分体，非姐妹染色单体之间没有交叉互换现象出现同源染色体联会现象、形成四分体，同源染色体的非姐妹染色单体之间常常有交叉互换现象分离与组合也不出现同源染色体分离，非同源染色体自由组合出现同源染色体分离，非同源染色体自由组合着丝点的行为中期位置赤道板减Ⅰ在赤道板两侧，减Ⅱ在赤道板断裂后期减Ⅱ后期【详解】不论的细胞的有丝分裂、无丝分裂、减数分裂还是细菌的二分裂，都有DNA复制过程，因此在细胞分裂过程中一定有DNA的复制，A正确；只有进行有丝分裂的细胞，在连续分裂过程中有细胞周期，B错误；真核细胞减数分裂时一定有同源染色体的配对，而有丝分裂、无丝分裂和原核细胞的二分裂均没有同源染色体的配对，C错误；真核细胞有丝分裂和减数分裂时一定有纺锤丝的出现，而无丝分裂和原核细胞的二分裂均没有纺锤丝的出现，D错误；故选A。
【点睛】本题考查细胞分裂的知识，考生识记细胞的分裂方式、明确各种细胞分裂过程和特点是解题的关键。
2.如图为细胞周期中细胞核的部分变化示意图，图示时期（）A. 既可能是分裂期的前期，也可能是末期B. 染色体数目和DNA分子数已加倍C. 细胞中正在形成纺锤体D. 是观察染色体形态和数目的最佳时期【答案】C【解析】【分析】有丝分裂不同时期的特点：（1）间期：进行DNA的复制和有关蛋白质的合成，即染色体的复制，DNA数目加倍，但染色体数目不变；（2）前期：核膜、核仁逐渐解体消失，出现纺锤体和染色体；（3）中期：染色体形态固定、数目清晰，是观察染色体形态和数目的最佳时期；（4）后期：着丝点分裂，姐妹染色单体分开成为染色体，染色体数目加倍；（5）末期：核膜、核仁重建、纺锤体和染色体消失．由此可见，图示细胞处于有丝分裂前期，据此答题。

B. 买办商人势力的恶性竞争
C。 金融业形势发生了变化
D. 资本主义世界市场的影响
【答案】D
【解析】
试题分析：
本题主要考查学生解读题干材料,获取有效信息,并作出正确认知和准确判断的能力.根据题干材料关键信息“1883年”、“外国丝市不振，洋商不购”等,结合所学知识，可知，由于资本主义世界市场的形成,导致国内丝织业出口困难，也就是说当时中国已经被卷入了资本主义世界市场。ABC三项，材料均无从体现,排除。故，本题正确答案选D。
【考点定位】古代中国经济·宋代商业·宋代海上丝绸之路的影响
9。日本史学家井上清在谈到明朝与日本的贸易时说:“和中国的往来不只是进行和平贸易、同时也伺机变为海盗，掠夺沿海居民.倭寇和北欧古代的海盗船，以及英国中世纪末的海盗兼贸易船是一样的。”该材料可证明
A。 日本与欧洲勾结共同掠夺中国
B. 明朝与日本贸易情况复杂多样
12.洋务运动推动了中国近代工业化的发展，有人说它是”有心栽花花不开,无心插柳柳成荫".这里的“花"和“柳"分别是指
A. 生产技术和新的思想文化
B. 国家富强和新的经济因素
C。 资本主义和新的工业企业
D. 经济体制和新的政治制度
【答案】B
【解析】
洋务运动时期“有心栽花”是指其目的，即学习西方先进技术以实现富国强兵；“无心插柳"指的是无意发展资本主义，因为资本主义发展会冲击封建统治；所以这里的“花”和“柳"应该指的是B；A错在了“新的思想文化"，C错在了“资本主义”，D与洋务运动的史实完全不符,故排除ACD.
点睛：根据材料的关键词“独立力量”“从官方取得捕鼠的特权"结合中国古代商业的特点即可得出答案.
