第I卷
第一部分阅读理解（共两节，满分40分）
第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。
A
An increasing number of students worldwide are considering studying abroad. The application process varies from country to country. If you’re looking for a university with a strong international outlook but feel swept over by all the application options, here is some guidance to get you started.
UK
International students must apply to universities in the UK through a system known as Ucas. This system allows students to apply to up to five universities with just one application. It costs ￡20 for a single choice or ￡25 for more than one choice.
The application consists of a series of questions to determine the student’s schooling and predicted grades. The biggest part of the application form is the personal statement, in which applicants should describe their personal interests and related experiences.
Switzerland
Switzerland has four official languages and is bordered by five countries so it is no surprise that its universities are among the most international in the world. International applicants may need to take an entrance exam if they have a foreign school certificate, and must also prove that they have a good grasp of the French language, usually through taking a language exam. The full application costs 50 Swiss Francs for a holder of a Swiss diploma and 150 Swiss Francs for holders of foreign diplomas.
Canada
International applicants have to write up a personal profile as part of their application, which is very similar to the personal statement required for a UK university application. Students will also have to prove their English-language competency—there are nine ways to meet the English Language Admission Standard, which are listed on many university websites.
Singapore
The process of applying to a Singaporean university is very much alike, but overseas students may be delighted to find that the domestic applicants have to cover the same procedures: filling out an online application form and submit identification documents, supporting documents and an application fee of S$20.
21. Which country requires international applicants know French well?
A. UK.
B. Switzerland.
C. Canada.
D. Singapore.
22. What part of the application is similar between the UK and Canada?
A. The application system.
B. The number of universities.
C. The application cost.
D. The personal statement.
23. What’s special about the application process in Singapore?
A. Applicants need to pay a lot.
B. It is much simpler than elsewhere.
C. It’s no different for native students.
D. The competition is even more fierce.
B
One day after more than a month of classes, I read aloud a paragraph from my book, recognizing all of the characters smoothly except for one. I sat back and started to register the achievement: I was actually reading Chinese. The language was starting to make sense. But before the sense of satisfaction was half formed, Teacher Liao said, “Budui!”
It meant, literally, “Not correct.” You could also translate it as no, wrong, nope, uh-uh. Flatly and clearly incorrect. There were many Chinese words that I didn’t know, but I knew that one well.
A voice in my head whined: All of the rest of them were right; isn’t that worth something? But for Teacher Liao it didn’t work like that. If one character was wrong it was simply budui.
“What’s this word?” I asked, pointing at the character I had missed.
“Zhe — the zhe in Zhejiang.”
“Third tone?”
“Fourth tone.”
I breathed deeply and read the section again, and this time I did it perfectly. That was a victory — I turned to Teacher Liao and my eyes said (or at least I imagined them saying): How do you like me now? There seemed to be some satisfaction in her eyes, but she simply said, “Read the next one.”
It was her way of teaching. Success was expected and failure criticized and immediately corrected. You were right or you were budui; there was no middle ground.
I grew to hate budui. The bu was a rising tone and the dui dropped abruptly, like building my confidence and then breaking down all at once. And it bothered me all the more because I knew that Teacher Liao was only telling the truth: everything I did with the language was budui. I was an adult, and as an adult I should be able to accept criticism where it was needed. But that wasn’t
the American way; I wanted to be praised for my effort; I didn’t mind criticism as long as it was candy-coated. In China, the single B on the report card matters much more than all the As that surround it. Keep working; you haven’t achieved anything yet.
And so I studied. I was frustrated but I was also stubborn; I was determined to show Teacher Liao that I was dui.
24. Which of the following can best replace “whined” in Paragraph 3?
A. burst out.
B. gave in.
C. returned.
D. complained.
25. What did the writer expect from Teacher Liao after he tried again?
A. Immediate correction.
B. A new challenge.
C. An encouraging response.
D. A strict comment.
26. How did the writer feel about the Chinese way of teaching?
A.
Weakness-focused.
Candy-coated. B.
Interest-driven. D.
Criticism-absent.
C.
27. What can we infer from the text?
A. The writer was struggling with Liao’s teaching.
B. The American way of teaching is better for adults.
C. The writer was not gifted in language learning.
D. Teacher Liao was not friendly with her students.
C
In the winter of 1664-65, a bitter cold fell on London in the days before Christmas. Above the city, an unusually bright comet (彗星) shot across the sky, exciting much prediction of a snow storm. Outside the city wall, a woman was announced dead of a disease that was spreading in that area. Her house was locked up and the phrase “Lord Have Mercy On Us” was painted on the door in red.
By the following Christmas, the virus that had killed the woman would go on to kill nearly 100,000 people living in and around London — almost a third of those who did not flee.
In The Great Plague (瘟疫), historian A. Lloyd Moote and microbiologist Dorothy C. Moote provide a deeply informed account of this plague year. Reading the book, readers are taken from the palaces of the city’s wealthiest citizens to the poor areas where the vast majority of Londoners were living, and to the surrounding countryside with those who fled. The Mootes point out that, even at the height of the plague, the city did not fall into chaos. Doctors, nurses and the church staff remained in the city to care for the sick; city officials tried their best to fight the crisis with all the legal tools; and commerce continued even as businesses shut down.
To describe life and death in and around London, the authors focus on the experiences of nine individuals. Through their letters and diaries, the Mootes offer fresh descriptions of key issues in the history of the Great Plague: how different communities understood and experienced the disease; how medical, religious, and government bodies reacted; how well the social order held together; the economic and moral dilemmas people faced when debating whether to flee the city; and the nature of the material, social, and spiritual resources supporting those who remained. Based on humanity (人性), the authors offer a masterful portrait of a city and its inhabitants attacked by — and daringly resisting — unimaginable horror.
28. What can we learn from Paragraph 1?
A. A comet always follows a storm.
B. London was under an approaching threat.
C. London was prepared for the disease.
D. The woman was the beginning of the disease.
29. What do the Mootes say about London during the Great Plague?
A. The city remained organized.
B. The plague spared the rich areas.
C. The people tried a lot in vain.
D. The majority fled and thus survived.
30. Why do the Mootes focus on the nine individuals?
A. They were famous people in history.
B. They all managed to survive the Plague.
C. They provided vivid stories of humanity.
D. They united by thinking and acting as one.
31. What’s the purpose of this text?
A. To introduce a new book.
B. To correct a misunderstanding.
a
research.
new
report
C.
To
D. To show respect to the authors.
D
Rivers are the veins of the Earth, transporting the water and nutrients (营养物) needed to support the planet’s ecosystems, including human life. While many nutrients are essential to the survival of life, there is one element transported by water in rivers that holds the key to life and to the future of our planet — carbon.
Carbon is everywhere and understanding the way it moves and is either released or stored by the Earth system is a complex science in itself. Carbon starts its journey downstream when natural acid rain, which contains carbon dioxide from the atmosphere, melts minerals in rocks. This helps transform carbon dioxide to bicarbonate (碳酸氢盐) in the water that then flows in our rivers. This is a very long process, which is one of the main ways carbon dioxide is removed from the atmosphere. Carbon is transported by rivers to oceans and once that carbon reaches the ocean, it is stored naturally in deep sea sediments (沉淀物) for millions of years.
As carbon travels down a river, different processes may impact whether it continues to flow downstream or whether it is released into the atmosphere. For example, human engineering, like extensive dam construction, will result in dramatic changes to how water and sediments travel down the river. Some carbon that fails to reach the sea may return to the atmosphere in some way, which causes more warming.
Earth’s climate is closely related to the carbon cycle. We all know about the essential role of plants in consuming carbon dioxide, but do we know enough about rivers? Changing the chemistry and the course of rivers may have significant impacts on how they transport carbon. Remember: wherever we live, we all live downstream.
32. Where is the carbon in rivers originally from?
A. The atmosphere.
B. The rocks.
C. The acid rain.
D. The upstream areas.
33. Why is human engineering mentioned in Paragraph 3?
A. To show how important to life carbon is.
B. To explain how necessary it is to build dams.
C. To show how a natural process is interrupted.
D. To explain how humans fight global warming.
34. What does the author want to convey in the last paragraph?
A. We’d better move upstream to live.
B. We should protect plants along rivers.
C. We’d better seek more help from plants.
D. We should be cautious about river management.
35. What is the best title for the text?
A. What Humans Do with Rivers
B. How Rivers’ Transporting Carbon Counts
C. What the Carbon Cycle Means to Us
D. How Living Downstream Affects the Earth
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。选项中有两项为多余选项。
Imagine you are on a long car trip. It is night and you take a wrong turn onto a dark country road. With a sinking feeling, you realize that you have no idea where you are.
36 , and the answer is written in light. A shining compass face, with north, south, east and west at the four points, and a big needle are pointing at north. What a relief! You turn your car around and head in the right direction guided by the sky.
For migrating birds, finding their way over long distances through the darkest nights is their second nature. 37 — directions written by light and magnetism (磁力). Some birds journey thousands of miles in their twice-yearly journeys. 38 , like mountain ranges and rivers, to help decide the directions; but birds may also navigate using the stars, and by sensing — or even “seeing” — the Earth’s invisible magnetic field.
For many years, scientists have been studying what’s behind the strong ability of migrating birds to find their way to their winter and summer homes. Here is one thing that they agree on. 39 . This compass leads them to make their very first autumn flight in the direction that has been long-travelled by the rest of their species. 40 .
A. Then you glance up at the sky
B. So birds are born knowing which way home is
C. They do it in part by reading directions in the sky
D. Magnetism is important for all animals, especially birds and fishes
E. When they’re on the way, they take the advantage of familiar landmarks
F. Migratory baby birds are already equipped with a kind of present inner compass
G. In birds, migration means two-way journeys — onward journey and backward journey

My daughter loved dance, until she didn’t. After an 41 first year, I noticed her interest fading week by week. Then, one day, she slowly walked to me before class and asked if she could just 42 it.
My first reaction was to 43 her to “finish what you start”. 44 , sticking with something difficult can teach perseverance (毅力), discipline and confidence. But watching my first-grader 45 herself into each ballet position, I started to question how much 46 that “blanket advice” made. Is it really in my kid’s best 47 , or even practical, to make her stick to every commitment through until she reaches a bitter 48 ? What if there are different but 49 valuable qualities, which can be gained by 50 the things that are not right for her?
With the winter show approaching, I realized she needed to either 51 her class or commit herself to it. After a few days’ consideration, she 52 dance wasn’t for her — a choice I 53 . Quitting is never a black-and-white issue. Sometimes, it means 54 a barrier in your way to love something else. In my daughter’s case, ending dance made space for her new hobbies, such as horseback riding and Girl Scouts. She’s into them for now, but it is okay if that 55 changes.
As adults, we are accustomed to 56 the power of saying yes, but what about saying no? The ability to recognize when something isn’t an 57 investment of our time or energy is also important. As my daughter gets older, I want her to feel confident to 58 something that’s no longer meeting her needs. She shouldn’t be held back by the thought that she must 59 something at any cost 60 because she has started.
41. A. annoyed B. independent C. enthusiastic D. unbearable
42. A. make B. join C. skip D. try
43. A. advise B. invite C. allow D. order
44. A. In addition B. After all C. At most D. By contrast

Mama says all the dust is due to the drought. The dirt sifts into everything. It covers our clothes. We have to wash the dishes before each meal. We rarely drive the truck because Papa fears the dust from the road will ruin the motor. When my sister, Faye, and I walk to school, we wear kerchiefs over our mouths so we don’t breathe in the dirt. On days when the air is so bad that they close the school, we stay home and help Mama put wet sheets over the windows. But the dirt always finds a way in. Last Sunday, there was no dirt in the air, only bright spring sunshine and a clear blue sky. After lunch, Papa headed out to the field to check on the cattle while I played with Faye in the yard. The temperature suddenly dropped. I looked to the west and saw a huge black cloud of dust. All the birds flew away. “I must warn Papa,” I thought to myself. To avoid her panicking, I gently told Faye to go back inside where she would be safe, and then headed off to the field.
高三数学一模考试归纳3篇.doc
高三数学一模考试总结3篇 高三数学一模考试总结篇一： 一、试卷分析 作为高三开学后的第一次一模考试，本试卷整体结构及难度分布合理，贴近全国卷试题，着重考查基础知识、基本技能、基本方法(包括基本运算)和数学基本思想，对重点知识作了重点考查，主要检测学生对基本知识的掌握以及解题的一些通性通法。试题力求创新。理科和文科试题中有不少新题。这些题目，虽然素材大都源于教材，但并不是对教材的原题照搬，而是通过提炼、综合、改编新创为另一个全新的题目出现，使考生感到似曾相似但又必须经过自己的独立分析思考才能解答。 二、答卷分析 通过本次阅卷的探讨和本人对试卷的分析，学生在答卷中存在的主要问题有一下几点： 1、客观题本次考试在考查基础知识的同时，注重考查能力，着重加强对分析分问题和解决问题能力的考查，送分题几乎没有，加大了对知识综合能力与理性思维能力的考察，对于我们这类学生答题比较吃力，客观题得分较低，导致总分低。 2. 基础知识不扎实，基本技能和方法掌握不熟练. 3. 审题不到位，运算能力差，书写不规范. 审题不到位在的第18题表现的较为明显。这是一道概率题，由于审题不到位致使将概率模型搞错、在(Ⅰ)问中学生出现结果重复与遗漏的现象严重导致后面全错，还有不会应用数学语言，表达五花八门。在考生的试卷中，因审题不到位、运算能力差等原因导致的书写不规范问题到处可见. 4. 综合能力不够，运用能力欠佳. 第21题为例，这道题是导数问题(Ⅰ)求单调区间，(Ⅱ)求
恒成立问题(Ⅲ)最值问题由于学生综合运用能力较弱，致使考生不知如何分类讨论，或考虑问题不全面，导致解题思路受阻。绝大部分学生几乎白卷。 5. 心态不好，应变能力较弱. 考试本身的巨大压力，考生信心不足，造成考生情绪紧张，缺乏冷静，不能灵活应变，会而不对、对而不全，甚至会而不得分的情形常可见到 三、教学建议 后阶段的复习，特别是第二轮复习具有承上启下，知识系统化、条理化的作用，是促进学生素质、能力发展的关键时期，因而对讲练、检测等要求较高，如何才能在最后阶段充分利用有限的时间，取得满意的效果?从这次的检测结果来看： 1、研读考纲和说明，明确复习方向 认真研读考试大纲和考试说明，关注考试的最新动向，不做无用功，弄清了不考什么后，还要弄清考什么，做到有备无患。 2、把所学知识和方法系统化、网络化 (1)注重基础知识，整合主干内容，建构知识网络体系。专题训练和综合训练相结合，课本例习题和模拟试题都重视，继续查漏补缺，归纳总结，巩固和深化一轮复习成果。 (2)多思考感悟，养成良好的做题习惯。分析题目时，由原来的注重知识点，渐渐地向探寻解题的思路、方法转变。做到审题三读：一读明结构，二读抓关键，三读查缺漏;答题三思：一思找通法，二思找巧法，三思最优解;题后三变：一变同类题，二变出拓展，三变出规律。以此总结通性通法，形成思维模块，提高模式识别的能力，领悟数学思想方法，从而提高解题能力 3、合理定位，量体裁衣

高三一模化学考试总结【一】 通过模拟考试让我对自己近段的教学思路与方法有所反思。考试结果反应的主要问题：学生基础知识不扎实，有的学生不能灵活运用所学知识，有一些类型的题目学生没有见过，不知该从何入手，导致得分太低，主要原因：复习不到位，基础知识不扎实。 一、对学生学习引导的反思 高中的化学是一门很重要的学科，但是“化学难学”的印象可能会使不少学生望而却步。因此初三的教学首先是要正确的引导，让学生顺利跨上主动学习化学这个大的台阶，其次是要让学生建立一个良好的化学知识基础，然后根据学生的具体情况选择提高。通过分期渗透，逐步提高。通过降低台阶，减少障碍，真正能够把学生吸引过来，而不是把学生吓跑了，可是，我并没有很快领会这种意图，因而在实际教学中不注意知识的形成过程，只靠生硬的讲解，只重视告诉结论，讲解题目，这怎么能怪学生对化学产生畏难情绪呢?学生如果对化学失去兴趣，对基本概念搞不清楚、对知识掌握不牢也就不足为怪了!如果我作为引路者有意识的降低化学学习的门槛，先将学生引进门，哪怕先是让学生感觉到“化学好学”的假象，我都是成功的。 二、对教学目标的反思 首先，知识、能力、情意三类教学目标的全面落实。对基础知识的讲解要透彻，分析要细腻，否则直接导致学生的基础知识不扎实，并为以后的继续学习埋下祸根。比如，教师在讲解“如何正确书写化学方程式”时，如果对“配平”讲解的不透彻，学生在后来的学习中就经常出现化学反应方程式不能配平的现象;对学生能力的训练意识要加强，若留给学生思考的时间少，学生的思维能力没有得到有效的引导训练，导致学生分析问题和解决问题能力的没有提高;还有就是要善于创设化学情景，让学生感觉到化学离生活很近。总之我要在教学活动中从一个知识的传播者自觉转变为与学生一起发现问题、探讨问题、解决问题的组织者、引导者、合作者。 其次，对重点、难点要把握准确。教学重点、难点正确与否，决定着教学过程的意义。在化学教学活动开始之前，首先要明确教学活动的方向和结果，即所要达到的质量标准。在教学目标中一节课的教学重点、难点如果已经非常明确，但具体落实到课堂教学中，往往出现对重点的知识没有重点的讲，或是误将仅仅是“难点”的知识当成了“重点”讲。这种失衡直接导致教学效率和学生的学习效率的下降。 三、对教学方法的反思 2017年河南省濮阳市高考英语一模试卷 第一部分听力（共两节，满分30分） 1．Who will the man call？ A．His wife． B．His boss． C．A taxi driver． 2．What does the man suggest the woman do？ A．Wait on the phone． B．Order the pizza online． C．Drive to the pizza place． 3．What does the woman want to do？ A．Make some coffee． B．Buy a coffee maker． C．Learn to make a video． 4．What will the man do at 3o'clock on Friday？ A．Go to school．B．Meet the doctor．C．Take the woman's shift．5．What does the man think of the lecture？ A．Excellent． B．Difficult． C．Boring． 6．听第6段材料，回答6、7题． 6．Who will send the file？ A．Sam．B．Carol．C．Lucy． 7．Where is the woman？ A．At the airport．B．In the officeC．In the hotel． 8．听下面一段对话，回答第8至第10三个小题． 8．When did the woman get to London？ A．Last spring． 2019届高三数学一模考试质量分析 一、试题总体评价：注重基础、突出能力、难度稍大 本试题紧扣教材、《考试大纲》和《考试说明》，在注重基础的同时更加突出了对考生(运算、迁移、应变等)能力的考查，符合当前高考命题基本原则与发展趋势。试题比较全面地考查了学生通过一轮复习后对基础知识与基本能力的掌握情况，充分体现了既注重基础又突出能力的特点。试题在全面覆盖了高中数学绝大多数高考考点的同时，对高中数学主干知识进行了重点考查，但由于我校一轮复习没有结束，而本试题有37分的试题学生没有复习到，对他们来说难度就大，且大部分题目来源于各省高考试题，难度较大。 二、学生答题情况分析：基础不牢,能力不强, 缺乏策略 1、学生基础知识不牢，解题能力较差：如试卷的第1题、第5题、第6题、第8题、第13题、第17题都是一些常规题，解题思路存在一定问题。 2、运算能力不强：具体表现在试卷第15、20题的运算，尤其是解题思路和方法对的学生由于计算复杂而没有结果，很让人遗憾。 3、审题不清：如试卷第1题、第12题均存在审题不清的问题。 4、推理归纳能力和数形结合解决问题能力差：如试卷第11、12、13、16、19、22题等题尤为明显。 5、解答策略缺乏，抓分意识不强：根据学生考卷，考后教师与部分学生交谈，了解到部分学生心理素质较差，情绪不够稳定，考试 过程中有些心慌意乱，碰到某些棘手题乱了阵脚，在一些选择题，填空题上花费了较长时间，致使后面某些有能力做出的解答题因无时间而白白丢掉。 三、下阶段的教学措施 1、要认真回顾和反思“一轮”复习中各个环节的得失，认真分析和总结“一模”测试中学生存在的不足，科学规划和严密组织后阶段的各项备考工作。 ⑴高三第一轮复习将于3月底结束，这轮复习主要是：梳理知识、构建网络、训练技能和兼顾能力。根据学生实际与教学要求精心设计练习引领学生主动参与知识构建和技能训练，并把课前、课堂和课后进行有机整合，使学生对数学的基本知识、基本技能和重要的数学思想方法能经历恢复记忆、加深理解到巩固熟练的过程。通过“一模”测试，我们要研究以前的各项工作和措施哪些是有效的，哪些还存在着不足，还应采取何种策略加以改进和弥补等等，都要有思考、有措施、有策略，努力使我们的复习教学工作有较强的科学性和针对性，进一步提高实效性。 ⑵高三第二轮复习于4月份开始，这轮复习是：强化基础、完善网络、熟练技能和培养能力。我们采取的措施是以知识块为载体，组织专题复习，要求做到：使学生能理清块内的知识、方法和相关的数学思想方法，熟悉解决问题的方法与途径，了解相关知识与其它数学知识的区别与联系等。即根据高考要求，把高中数学的主干知识和重要内容予以重点关注，并穿插数学思想方法。从“一模”测试情况看，

To encourage people to come, Baudry drove a large vehicle around to give people a ride to the baths. He called the vehicle an omnibus, 1 is a Latin word meaning “for everyone”. Then he 2 (notice) that many passengers would get off at stops during the journey to the baths. So Baudry shifted the focus of his omnibus service. He created a permanent route for passengers 3 (board) and get off. Eventually, the omnibus became known 4 (simple) as a bus. B In the film Frozen 2, Elsa and Anna are sisters who live in a kingdom called Arendella. Elsa is born 5 special power s that allow her to create ice and snow. Elsa’s powers are considered dangerous, 6 she must hide them. Eventually she loses control and changes summer to winter. Then Elsa flees from home, and Anna goes on a dangerous journey to find her sister. Along the way, Anna teams up with a man 7 (name) Kristof and his reindeer（驯鹿）)Sven. A talking snowman, Olaf also accompanies them. In the end, it’s Anna’s love for her sister that saves the day. C According to the World Wildlife Fund, only about 3,890 tigers are left in the wild. India is home to 70 percent of them, and its role in 8 (ensure) the big cat’s survival can’t be understated. Tiger numbers in India are believed to have dropped from about 40,000 at the beginning of the 9 （19）century to just 1,800 in the early 1970s, when India launched the conservation program Project Tiger. Kanha was one of the original nine 10 (reserve) set up under that program. 1 山东省济南市2017届高三数学一模考试试题 文 本试卷分第I 卷和第Ⅱ卷两部分，共5页．满分150分．考试用时120分钟，考试结束后，将本试卷和答题卡一并交回． 注意事项： 1．答题前，考生务必用0.5毫米黑色签字笔将自己的姓名、座号、考生号、县区和科类写在答题卡和试卷规定的位置上． 2．第I 卷每小题选出答案后，用2B 铅笔把答题卡上对应题目的答案标号涂黑；如需改动，用橡皮擦干净后，再选涂其他答案标号，答案不能答在试卷上． 3．第Ⅱ卷必须用0.5毫米黑色签字笔作答，答案必须写在答题卡各题目指定区域内相应的位置，不能写在试卷上；如需改动，先划掉原来的答案，然后再写上新的答案；不能使用涂改液、胶带纸、修正带．不按以上要求作答的答案无效． 4．填空题请直接填写答案，解答题应写出文字说明、证明过程或演算步骤． 参考公式： 锥体的体积公式：13 V Sh =，其中S 是锥体的底面积，h 是锥体的高. 第I 卷(共50分) 一、选择题：本大题共10个小题，每小题5分，共50分．每小题给出的四个选项中只有一项是符合题目要求的． 1.已知集合{} {}220,1,0M x x x N =--==-，则M N ?= A. {}1,0,2- B. {}1- C. {}0 D. ? 2.已知复数21i z i -= +（i 为虚数单位），则在复平面内复数z 所对应的点在 A.第一象限 B.第二象限 C.第三象限 D.第四象限 3.已知x R ∈，则“2x >”是“2320x x -+>”成立的 A.充分不必要条件 B.必要不充分条件 C.充要条件 D.既不充分也不必要条件 4.2017年2月20日，摩拜单车在济南推出“做文明骑士，周一摩拜单车免费骑”活动.为了解单车使用情况，记者随机抽取了五个投放区域，统计了半小时内骑走的单车数量， 绘制了如图所示的茎叶图，则该组数据的方差为 A.9 B.4 C.3 D.2 5.已知双曲线()22 2210,0x y a b a b -=>>上一点到两个焦点的距离分别为10和4，且离心率为2，则该双曲线的虚轴长为 A. 3 B. 6 C.
