(每小题2分)Passage One (10%)College brings together people from all walks of life. There are so many different types of people in the world but if you go to a college campus, you are sure to find at least one of every kind. The great part about being here with so many different people is that you get to interact with some interesting characters and see how to deal with them. You will meet the people you dread the most, the smart ass, the brain, or the unique spirit, but no matter who it is that is your worst nightmare to be around you will always be paired up with them in a group project. When you get into the real world you are not going to be able to pick your boss or coworkers. Interacting with these people in college and living with different roommates will help you learn how to cooperatePart II Reading Comprehension (40 % )with the people in life you find so unpleasant. College life is fun. The fact that I have been here for a short time just means it has not yet been a life changing experience to me. If I were to give any tips on how to survive, it would not be how to survive college, but how to survive life. I would have to say that one should be outgoing and live life to the fullest. Meet new people whenever you can because they just may be a major influence in your life. Also, get your work done before you go out and party. Lastly, I would have to say, in life if you ever feel lost or alone, talk to someone about it. Everyone gets depressed at times in their life and there is always someone who will listen to your problems.26.

What does the author say to do if you’re depressed?A) Go somewhere by yourself B) Talk to someone about itC) Try to forget about it D)See a psychologist immediatelyPassage Two（10%）How can English teachers accelerate the language learning of their students? One way is to teach students how to learn more effectively and efficiently. Learning strategies are procedures or techniques that learners can use to facilitate a learning task. Instructing students of English in learning strategies can help them become better learners. In addition, skill in using learning strategies assists students in becoming independent, confident learners. Finally, students become more motivated as they begin to understand the relationship between their use of strategies and success in learning English.Students need to develop an awareness of the learning process and strategies that lead to success. Students who reflect on their own thinking are more likely to engage in planning how to proceed with a learning task, monitoring their own performance on an ongoing basis, finding solutions to problems encountered, and evaluating themselves upon task completion. These activities may be difficult for students accustomed to having a teacher who solves all their learning problems and is the sole judge of their progress.Teachers need to encourage students to rely more on themselves. Because learning strategies are mental processes with few observable manifestations, teachers need to find ways to make the strategies as concrete as possible. When students are able to use the strategies their teachers have taught them, and to do so without prompting, then they need to explore new strategies, new applications, and new opportunities for self-regulated learning.31. Better learning strategies can make language learning more _______.A) fun B) interesting C) efficient D) exciting32. Students who reflect on their own _________ will be more successful in learning.A) thinking B) evaluation C) performance D) activities33. Teachers should encourage students to rely more on _______.A) books B) notes C) tutors D) themselves34. Learning strategies are unobservable mental processes, so teachers should make them ______.A) simpler B) more familiar C) more concrete D) more applicable35. Which of the following statements is true?A) Students learn learning strategies from the teachers only.B) Learning strategies are completely unobservable.C) Students need to explore new learning strategies for themselves.D) Teachers are the sole judges of students’ progressPassage ThreeFor many years, we have been led to believe that a person’s intellectual intelligence (measured as IQ, or intelligence quotient) is the greatest predictor of success. Society assumes that people with high IQs will naturally accomplish more in life. Schools often use IQ test results to choose children for gifted programs and advanced placement courses. Some companies even use the results as a criterion for hiring employees.We have been conditioned to judge intelligence with these numbers. In the past 10 years, however, researchers have found that this isn’t necessarily the case—that in actuality, a person’s emotional intelligence (EQ) might be a greater predictor of success than his or her IQ.What is emotional intelligence? In the early 1990s, Dr. John Mayer, Ph.D., and Dr. Peter Salovey, Ph.D., introduced the term “emotional intelligence” in the Journal of Personality Assessment. They used this term to describe a person’s ability to understand his or her own emotions and the emotions of others and to act appropriately based on this understanding. Then in 1995, psychologist Daniel Coleman popularized this term with his book Emotional Intelligence: Why It Can Matter More Than IQ. Emotional Intelligence is about having empathy for others. It is about standing up for what you believe in a tactful and respectful way. It is about not jumping to conclusions, but getting the whole picture before you react. The key to emotional intelligence is an understanding of your emotions and the emotions of others, and acting in the most appropriate way based on that understanding. Having a healthy emotional intelligence is very important in order for human beings to live happy and successful lives. Healthy emotional intelligence helps usset our personal boundaries, make decisions about our lives, and communicate with the people we love.Keep in mind that your emotional intelligence can change. People are always evolving. You can increase your EQ at any point in your life by learning to identify your emotions and taking responsibility for those emotions. And just as easily as you can increase your EQ, you can also decrease it. You must continue to identify and work on areas within yourself that need work.36. Who was the first to put forth the term “emotional intelligence”?A) John Mayer.B) Daniel Coleman.C) Peter Salovey.D) John Mayer and Peter Salovey.37. According to this passage, which of the following is true?A) People with high IQs are sure to achieve more in life.B) The IQ test results can sometimes decide whether the applicants will be hired by somecompanies.C) IQ was first used to describe a person’s ability to understand his or her own e motions and theemotions of others.D) You cannot change your EQ unless you increase your IQ.38. What does the underlined part “we have been led to believe” (Para.1) imply?A) We have been forced to believe it by some people.B) We have been persuaded to believe it by some people.C) We have been influenced by the misbelief of many people.D) We have been willing to follow the idea of other people.39. What are the benefits a healthy emotional intelligence can bring us?A) Help us set our boundaries in life.B) Help us make decisions about our lives.C) Help us communicate with those we love.D) All of the above.40. What is the passage mainly about?A) The functions of IQ and EQ.B) The Differences between IQ and EQ.C) The importance of IQ and EQ.D) The history and characteristics of EQ.Passage FourIn the United States and Canada, a prom, short for promenade, is a formal (black tie) dance held at the end of an academic year. In the United Kingdom, the term is more widely understood to be in reference to a season of classical concerts or “proms”, which have been held between July and September since 1895, today run by the BBC. The British synonym for the North American event would be Leavers’ Ball, Leavers’ Dinner, Leaver’s Dance or informally Leavers’ Do, closer to the Australian description. In Canada the terms Grad or Formal are most common and the event is usually only held for those in their graduating year of high school or middle school.While smaller schools may hold a school prom open to the entire student body, large high schools may hold two proms, a junior prom for those finishing their 11th grade year and a senior prom for those who are finishing their high school years. The name is derived from the late nineteenth century practice of a promenade ball.Common prom activities include dining, dancing, the crowning of a prom King and Queen, and socializing.Some universities and colleges have proms as well, depending on the size of the graduating class in a department.Proms can be very expensive events.For many parents, however, the biggest concern isn’t the cost of attending prom, but worry about the risky behaviors associated with proms, teens driving under the influence of alcohol, drugs and unsafe sex, and how to ensure their son or daughter arrives home safely after attending prom. Therefore, some measures should be taken to keep the participants safe, lessen the fear and anxiety often accompanying prom night, thereby making this special occasion something to enjoy and remember with fond memories.41. Which of the following is NOT mentioned as one of the common prom activities?A) Socializing. B) Classical concerts.C) Dining. D) Dancing.42. The British synonym for the North American event “prom” is ______.A) Leavers’ Do B) PromenadeC) Grad D) Formal43. Large high schools may hold ______.A) a school prom open to the entire student bodyB) a junior prom for those finishing their 11th grade yearC) a senior prom for those who are finishing their high school yearsD) both B) and C)44. In the last paragraph, the underlined word “participants” refers to ______.A) parents B) teachersC) students D) organizers45. The biggest concern for many parents is ______.A) their children’s safety B) the cost of attending promC) driving under the influence of alcohol D) drugs and unsafe sexDirections:In this section, there 15 sentences with 15 blanks.

For young adults who love to read, finding some good books to read is very essential. Writing a book review can help you to improve your language and writing skills.The Book ThiefListed onThe New York Times Children’s Best Seller List for over 100 weeks, The Book Thief by Markus Zusak is the story of a young girl in the Nazi camps set during World War II.

It’s a must read that describes the situation of a family in the evils of wars through the eyes of a teenager.Animal FarmAnimal Farm is one of the most popular books by George Orwell. It is just a reflection of the Stalin and World War II period that has been so creatively presented in this book.

And thishas great consequences on our health, our job performance, our relationships and our happiness. What is needed, she ly declares, is nothing short of a sleep revolution. Only by renewing our relationship with sleep can we take back control of our lives.In her bestseller Thrive, Arianna wrote about our need to redefine success through wellbeing, wisdom, wonder, and giving. Her discussion of the importance of sleep as a gateway to this more fulfilling way of living struck such a powerful chord (弦) that she realized the mystery and transformative power of sleep called for a fuller investigation (调查).The result is a scientifically sweeping and personal exploration of sleep from all angles, from the history of sleep, to the role of dreams in our lives, to the consequences of sleep deprivation (剥夺), and the new golden age of sleep science that is showing the vital role sleep plays in our every waking moment and every aspect of our health — from weight gain, diabetes, and heart disease to cancer and Alzheimer’s.In The Sleep Revolution, Arianna shows how our cultural removal of sleep as time wasted damages our health and our decision-making and our work lives and shortens our personal lives. She explores all the latest science on what exactly is going on while we sleep and dream. She decides the dangerous sleeping pill industry, and all the ways of our addiction to technology disturb our sleep. She also offers a range of recommendations and tips from leading scientists on how we can get better and more restorative sleep.In today’s fast-paced, always-connected and sleep-deprived world, our need for a good night’s sleep is more important than ever. The Sleep Revolution both sounds the alarm on our worldwide sleep crisis and provides a detailed road map to the great sleep awakening that can help transform our lives, our communities, and our world.4.

It helps to slow down the pace of modern life.B. It warns people against taking sleeping pills.C. It warns the harm of inadequate sleep of people.D. It helps to stress the value of sleep to success.CIn June, 2021, a group of students from eight high schools in Winnipeg, the capital of Canada’s Manitoba province, will begin test-launching (试发射) a satellite the size of a Rubik’s cube.The one-kilogram Win-Cube satellite, named for its home city and its shape, will be put into low orbit. Once in space, it can perform for a few months or up to several years, communicating information that could help find the signs of earthquakes.There are 80 similar satellite projects worldwide, but this is the first high-school based program of its kind in Canada. 30 Manitoba high school students are having a hand in designing and building the satellite, in cooperation with aerospace (航空航天的) experts and 10 students from the University of Manitoba, and with support from two other organizations.The Win-Cube project is not something that goes on a piece of paper; it is real-world engineering, allowing high school students to have an opportunity to learn more about the exciting world of engineering through their participation in this challenging program. It is also taken as a wonderful example of the unique partnerships withinManitoba. Designing, building and launching a satellite with high-school participation will bring this world-class educational project into reality and Manitoba closer to space“These Manitoba high school students deserve congratulations for their enthusiasm, innovation (创新), and a strong love for discovery,” said Education, Citizenship and Youth Minister Peter Bjomson. “We want to make science more relevant, interesting and attractive to high school students by showing them how classroom studies can relate to practical experience in the workplace or, in this case, in space,” Bjomson added.The Win-Cube program is mainly aimed at inspiring a strong desire for discovery on the part of the students. It also shows Manitoba’s devotion to research and innovation and the development of a skilled workforce—all important drivers of knowledge-based economic growth.8. What can we learn from Mr. Bjomson? .A. Those Manitoba high school students are worth praising.B. The study of space can be practically made in classrooms.C. Manitoba high schools are famous for the study of space.D. Scientific research is too far away from high school students.9. What is the primary purpose of the project ? .A. To find the early signs of earthquakes.B. To relate studies to practical.C. To help high school students study real-world engineering.D. To inspire a strong desire for discovery among the students.10. According to the passage, what can we know about the Win-Cube satellite? .A. It is named after Manitoba and its shape.B. It is intended for international communication.C. It is designed like a Rubik’s cube both in shape and size.D. It is challenged by university students around the world.11. What may be the best title for the passage?A. Manitoba SchoolB. Win-Cube ProgramC. Space Co-operationD. Satellite LaunchingDAs summer approaches, many kids and teenagers may find that they have more time in hand. One great way to make use of the extra time is to go on an adventure and travel. Clearly, I am not a naturally adventurous person,but I have found that takingthe risk and challenging myself to explore and travel to unfamiliar places can be a very rewarding experience.Because I am usually quite busy during the school year, most of my travels take place during the summer. Over the past few summers, I have hiked in the Grand Canyon, explored Niagara Falls, and camped out in upstate New York. Although these experiences are varied, they are similar in that they instill (灌输) a sense of appreciation for nature and a more balanced view on life. When I hiked in the Grand Canyon, for example, I was in awe(敬畏) of the geological influences that shaped the canyon.Adventures, of course, are not limited to hiking. There are many other choices, such as camping, volunteering in a foreign environment and travelling to different countries. In my opinion, adventures are more enjoyable with family or a few friends. There is a sense of bonding that one only gets through spending time together in outdoor adventures. For example, when I was in Boy Scouts, I often went on weekend camping trips with my friends. When I came back from a Boy Scouts camping trip, I often was eager to go outside more and explore the parks and nature around me.Next fall, I will attend college. In the meantime though, I hope to make the most of my summer to explore and travel. Now, I am planning on hiking and camping out in Maine.When I visited Maine last fall, I was amazed by how beautiful it was and the tall trees and coasts that exist, and I really hope to enjoy the beauty of nature there this summer.12. We can learn from the first paragraph about the author?A. He is an adventurous person by natureB. He likes challenging himself by travellingC. He enjoys travelling with other adventurersD He needs others’ help when going on an adventure13. Which of the following can make people’s adventure more enjoyable according to the author？A. Going to different countries.B. Going to unfamiliar places.C. Travelling withtheir family or friends.D. Travelling to distant places by themselves.14. What will the author do this summer？A. Explore Niagara Falls.B. Hike in the Grand Canyons.C. Camp out in upstate New York.D. Hike and camp out in Maine.15. Who is probably the author?A. A high school student.B. A college student.C. A friendly guide.D. A warm-hearted teacher.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020年河南师范大学附属中学高三语文期末考试试卷及答案解析
2020年河南师范大学附属中学高三语文期末考试试卷及答案解析一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文字，完成各题。
材料一：中国家庭财富日益增加、中国家长对子女教育日益重视及中国以考试为主导的录取方式，使得我国课外辅导在教育行业中占据着至关重要的位置。
据统计，2017年中国城市学生每周平均花费10.6小时进行课外辅导。
随着升学压力的增长以及对优秀学业成绩的期望增加，越来越多的家长为孩子选择课后辅导。
特别是随着求学阶段临近高考，中国学生的K12课外辅导参与程度逐级提高，在高中阶段有超过一半的学生参与K12课外辅导。
大量持续而稳定的生源将推动中国课后辅导市场保持稳中増长。
2017年中国各阶段学生课外辅导参与程度（单位:％）（选编自温程辉《课外辅导市场规模将突破4000亿线上教育成发展新趋势》材料二：不少家长出于从众心理，为孩子学习加码，甚至将无数的兴趣班当成了学习的另一种工具。
而部分培训机构的种种洗脑式营销也在消费家长们的焦虑，进一步刺激家长的功利教育观，加剧揠苗助长，违背了教育育人为本的初心。
教育专家指出，教育有竞争，但不全是比赛，让教育回归本真，重视孩子成长发展的规律，是当前很多执着于“拼娃”却“越拼越迷失”的父母急需补上的一课，也是教育者需要正视的命题。
从2018下半年伊始，特别是在6月和8月，年初整顿教培政策进入落实检查阶段，整个教育培训行业迎来一次真正的震荡和洗牌。
2018年2月以来，教育部会同有关部门先后印发了《关于切实减轻中小学生课外负担开展校外培训机构专项治理行动的通知》关于健全校外培训机构专项治理整改若干工作机制的《通知》等，推动开展为期1年半的校外培训机构专项治理行动。
8月份，囯务院办公厅印发了《关于规范校外培训机构发展的意见》。
9月，教育部发布《关于面向中小学生的全国性竞赛管理办法（试行）》，竞赛及竞赛产生的结果不作为中小学招生入学的依据。
整改的成果是截止到12月12日，全国校外培训机构整改完成率达到90％。
