thought that he would never see his little friend again until he received a life-changing call．Clearly, a kind stranger reached out to tell him that his beloved cat was safe and sound and couldn’t wait to see him again!The cat went missing years ago, right before Robert was planning on moving from California to Ohio．The sad owner decided to give up his plans and stayed in California for the whole year looking for his missing friend, but in vain．“I remember at one point I was praying and I said, ‘God, I’ll do anything, just bring my Chebon back…’”, Robert said in a video posted on the Ventura County Animal Services．The cat seemed to have disappeared forever and Robert had no other choice than to move on．Then 7 years later, a woman noticed a cat that looked ill, so she decided to catch the animal and take him to the vet (兽医)．Luckily, the cat she found had a microchip (微型芯片), and in an instant, they knew who the owner of the 19-year-old cat was．That’s when Robert received a call saying that his cat was alive．“I was afraid there was some kind of mistake,” Robert said in the reunion video．The man decided to ride on a plane and fly all the way from Los Angeles to see his old friend．After finally seeing the cat, Robert immediately recognized his cat and burst into tears．After all these years, the two friends were back together．The touching moment was recorded by the animal shelter and was quickly spread on the Internet, leaving so many people in tears．35．What happened to Chebon 7 years ago?A．It was ill．B．It was hurt in an accident．C．It was lost．D．It was taken to the animal shelter．36．What does “in vain” mean in paragraph 2?A．without success．B．for no reason．C．in no time．D．at no cost．37．How did Robert feel when he received the call?A．Doubtful．B．Worried．C．Peaceful．D．Hopeless．38．What is the main idea of the passage?A．A video moved many people．B．A cat was saved by a woman．C．A man reunited with his missing cat．D．A man kept looking for his cat for 7 years．Binge-watching (追剧) your favorite TV series is bad for your brain．Dr．Randall Wright, based in Texas, said the need to watch episode (集) after episode has a similar influence on the brain to gambling (赌博)．What’s more, it often leads to social loneliness, snacking on junk food and a shortage of exercise and sleep, which, over time, is bad for the brain．When you let auto play start the next episode, you can find out what happens next and your brain receives good feedback, Dr．Wright wrote in an article．This right-away satisfaction is similar to gambling where even after a win, you are not satisfied and want to continue playing．With binge-watching, you are not satisfied with stopping after episode five and want to continue watching．This cycle coupled with the snacking and the long time sitting can lead to unhealthy changes in your brain and body over time．Dr．Wright said, “Binge-watching itself is not bad．It becomes problematic when you are watching a third, fourth or fifth episode instead of doing healthy activities．” But he said it is possible to avoid the bad influence of binge-watching with four tips, including staying away from salty, fatty, calorific foods, exercising before abinge-watching, setting an alarm for sleep and balancing TV viewing with socializing．If you add these tips to your binge-watching practice, you can create lasting healthy habits and still enjoy the now-and-then binge-watching time without hurting your brain．39．What might “it” in paragraph 1 refer to?A．Gambling．B．Binge-watching．C．TV series．D．Brain．40．In what way is binge-watching like gambling?A．The long time sitting．B．The changes of feeling．C．The snacking on junk food．D．The immediate satisfaction．41．What is paragraph 3 mainly about?A．The tips on how to develop a healthy lifestyle．B．The reasons why binge-watching is problematic．C．The ways to keep away from binge-watching．D．Do’s and don’ts of binge-watching．42．What may be the best title of the passage?A．Ill Health: The Result of AddictionB．Healthy Habits: A Must of A Better LifeC．Binge-watching: A Killer of Your BrainD．TV-Viewing: Gradual Harm on Your Health五、七选五Some shy people find that they can talk fine with their old friends, but struggle with strangers．They want to “fit-in” with new people, but it’s really not easy for them．43．．Work on Raising Self-confidenceHaving high self-confidence helps you to be outgoing because you get recognition from yourself．44．Be in the Present MomentShy people spend too much time in their heads．45．．Being mindful of the present moment increases social ability because you have “more to work with”．This improves your confidence, making you more likely to be outgoing．Say No to Limiting BeliefsSome people are so careful in conversations．They don’t want to say “wrong things”．They don’t like themselves around new people and can’t stand out because they’re afraid even to try．46．．So, plan to say something a little embarrassing about yourself in a conversation．The point is, you’ll prove to yourself it’s OK to be not always right．That way you’ll feel free to be social with people．Little by little you’ll get better．As you su cceed, you’ll grow confident to be more outgoing, which will lead to more social success．47．．A．Then, you’re in a positive state of finding more friends．B．The real problem is that the feeling is based on completely false beliefs．C．When you feel good abo ut yourself, what others think of you doesn’t matter so much．D．Here are some tips on how to be more outgoing and be social with people．E．They could improve their social skills through these ways．F．Because of this, they don’t catch helpful details of the moment．G．You’ll know you can fit in whenever and wherever you like．六、书面表达48.假定你是高一新生李华，你的美国笔友David来信询问你的近况，请你用英文给他写一封电子邮件，内容包括：1.难忘的军训；2.结识的新朋友/新老师；3.个人感悟。

x =为增函数知，函数2(4)y f x x =-的递减区间是24(0)y x x y =->的减区间，由二次函数可知，当[2,4)x ∈时满足条件，故函数2(4)y f x x =-的递减区间是[2,4)x ∈，故答案为：[)2,4【点睛】关键点点睛：复合函数的单调性满足“同增异减”，注意在对数型复合函数中，真数必须满足大于0是解题的关键，属于中档题.15．关于x 的方程20ax x a

Imaginate FestivalC. The RoyalEdinburghMilitary TattooD.EdinburghInternational Film FestivalBLosing your ability to think and remember is pretty frightening. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips you probably needn’t worry. There are pretty clear differences between signs of dementia and age-related memory loss.After age 50, it’s quite common to have trouble remembering the namesof people, places and things quickly, says Dr. Kirk Daffner of Brigham and Women’s Hospital inBoston.The brain ages just like the rest of the body. Certain parts become smaller, especially areas in the brain that are important to learning, memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. But if you forget the plot of the movie or don’t remember even seeing it, that’s far more concerning, Daffner says.When you forget entire experiences, he says, that’s “a red flag that something more serious may be involved”. Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrongBut even then, Daffner says, people shouldn’t panic. There are many things that can cause confusion andmemory loss, including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications (药物) like antidepressants.You don’t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory. And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive(认知的) reserve, Daffner says.“Read books, go to movies, take on new hobbies or activities that force one to think in novel ways, ” he says. In other words, keep your brain busy and working. And also get physically active, because exercise is a knownbrain booster4. Why does the author say that one needn’t be concerned about memory slips?A. Not all of them are related to one’s age.B. Not all of them are symptoms of dementia.C. They occur only among certain groups of people.D. They are quite common among fifty-year-old people.5. Which memory-related symptom should people take seriouslyA.

He teaches in the area where having electricity is something of a luxury and students have no access to mobile apps or computers, which became a problem when Guatemalan government had to choosedistance education for students at home because of COVID-19 inmid-March.Gerardo Ixcoy felt that he had to teach those children living far from the digital world. After all, education is a universal right. But what was the solution?Gerardo bought himself a secondhand tricycle with his savings. Once he had the tricycle, the next step was to change it into a classroom on wheels. He put a roof with a solar panel（太阳能电池板）on it, along with a screen toavoid the spread of COVID-19. He fixed a whiteboard on it so he could explain to the students the basics of primary education：math, the local language and the national language Spanish.The purpose of the solar panelis to provide constant power for a small loudspeaker so he can teach from a distance. It's a matter of respecting the healthy distance required to be safe from the virus. He, the teacher, stays outside, and the student participates from his or her house.He tries to visit his students at least twice a week, riding his classroom — cycle. The children he serves say that, although he visits them for only a few hours a week, they look forward to it. They appreciate his visit because they know he has limited time he can devote to them. They must take advantage of it to learn.8. What happened to Gerardo Ixcoy's students because of COVID-19?A. They chose to have classes in groups.B. They had to stop all the classes.C.

In his student's house.C. On the school playground.D. Outside his student's house.11. What can be the best title of the story?A. Love breaks down barriers.B. Hard work pays off.C. Time is money.D. Education is the key to success.DThere are similarities and differences between high school life and college life.For one thing, there are several similarities between high school life and collegelife. First, the most important task in high school and college is both studying. Studying is the most important as a student. Second, we need a goal to fight for in both high school life and college life. To lead a meaningful life, we have to set up a goal to achieve.For another, there are also some differences between high school life and college life. First, our studying is also the biggest difference. In high school, we are required to follow our teachers' steps and finish theirassignmentsevery day. While in college, there are no teachers giving such detailed requirements to us and we can choose study or not according to our own willing. What and how to study totally depends on us. Therefore, the ability of self-control is very important in college life. Second, the flexibility (灵活性) of time is another difference. In high school, we have no much leisure except for our time of study. However, in college, we have much controlled by ourselves except the time of classes. And we have more time to do what we like. Finally, college lifeis much more various and richer. Besides study, we can attend many other activities, which make our college life more wonderful.In brief, there are both similarities and differences between high school life and college life. However, no matter we are in which period, we need to make full use of every day so that we will never feel regretful.12. Why do students need a goal to fight in high school and college?A. To enter a good college.B. To avoid living a meaningless life.C. To develop the ability of control.D. To meet their parents’ satisfaction.13. What does the underlined word “assignments” in paragraph 3 probably mean?A. Projects.B. Tasks.C. Goals.D. Dreams.14. Which is the correct structure of the passage?A. ①-②③-④B. ①②-③-④C. ①-②③④D.①②-③④15.

2020-2021学年菏泽市第一中学高三英语月考试题及参考答案
2020-2021学年菏泽市第一中学高三英语月考试题及参考答案第一部分阅读（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、D四个选项中选出最佳选项ASpeaking with people on the phone is pretty rare these days. Most people use e-mail or messaging apps when they need to communicate with someone. Sometimes, though, making a call is unavoidable. This simple act can actually be a nightmare for some people. Their hearts race and their hands sweat at the very thought. If this sounds familiar to you, you might be one of the millions of people who suffer from telephobia—the fear of speaking over the phone.Telephobia is a form of social anxiety, although people who feel perfectly comfortable in social situations may also experience telephobia. When speaking face-to-face, we give off lots of facial or bodily cues that help each other follow the conversation. This is not the case over the phone. And the idea of speaking into this void（真空）makes people terrified that they will freeze up, stumble over their words（失言）, or lose control of the conversation and look foolish In fact, telephobia is very similar to thefear people feel before putting on a performance in front of a big audience. However, there are things that one suffering from thin condition can do to reduce this fear and make phone calls at least somewhat bearable.One thing that those with telephobia can do before a call in smile. It may sound silly, but smiling before doing something stressful can help you feel more relaxed. It won't delete the anxiety altogether, but it will take the edge off it.Similarly, imagining how the call will go before you make it can also help things go more smoothly. Running through a positive conversation in your head will make you feel less nervous and may help you predict any possible problems. There's no need to spend hours on this, just a few minutes thinking up a general idea of what you want to say. You can even write down some brief notes to remind yourself of your talking points. This is particularly useful for dealing with the fear of not being able to express yourself naturally.And finally, when faced with receiving a call, you don't always have to pick up. There's nothing wrong with calling the person back later when you feel more comfortable.So the next time your phone starts ringing, remember—speaking on the phone doesn't have to make you sweat. The important thing is to be aware of your fear and take steps to deal with it.1. According to the article, which situation can cause a feeling similar lo telephobia?A.Speaking face-to-face to a good friend.B. Performing in front of a large audience.C. Running in a race without proper shoes.D. Using a messaging app while on the subway.2. Which of the following is NOT mentioned as a way to deal with telephobia?A.Imagining how the call will go before you make it.B. Standing on the edge of a tall building while making a call.C. Calling someone back later instead of answering their phone calls right away.D. Writing down some brief notes to remind yourself of your talking points.3. What is the main purpose of the passage?A. To present ways to ease telephobia.B. To explain the development of telephobiaC. To introduce the influence of telephobia.D. To give the reason why someone suffers from telephobia.BWe asked four people who watched an online talk on technology and communication by Sherry Turkle for their opinions.Fred:The talk certainly gave me plenty of food for thought about how technology is changing our behaviour. People are constantly multitasking, whether it be emailing during meetings or texting in the checkout queue. It’s as if we can’t bear to miss out on what our online friends are up to, so we juggle the real and online world. My greatest concern is that we don’t give our brains a chance to switch off. It’sthese precious momentswhen we actually process information that helps us make important decisions.Jeremy:It was a fascinating talk and the speaker really hit the nail on the head with a couple of things. Take parental influence, for instance. How can we expect teenagers not to text while doing their homework when they witness their parents posting on social media while cooking the evening meal or waiting at a red light?Kath:So much of what the speaker said rang true. I honestly believe there’s a danger that the more connected we are, the more isolated we feel. I don’t think this is such an issue for my generation who’ve lived withouttechnology for so long. We know how to be alone. But the under 20s are another kettle of fish. They’re so busy communicating that they never experience the feeling of solitude and run the risk of not learning how to enjoy their own company.Carl:I’m not sure to what extent I agree that people are more alone, but the way we communicate has certainly evolved. The speaker makes a good point about how we’re getting used to talking with machines like Siri or robots, which are totally lack of experience of human life. But despite such limitations, we seem to be expecting more from technology and less from each other.4. What does the underlined phrase “these precious moments” in paragraph 2 refer to?A. When our brains are free.B. When we emailing during meeting.C. When we texting in the checkout queue.D. When we juggle the real and online world.5. What suggestion may Jeremy give to the parents?A. Accompany their children when they are doing homework.B. Prevent their children using phone while doing homework.C. Set a good example for their children on using phone properly.D. Stop posting on social media in face of their children.6. What does Kath worry about the under 20s generation?A. They communicate more with others.B. They use more technology.C. It’s difficult for them to find companies.D. They don’t know how to be alone.7. What is Carl’s attitude towards the use of technology in communication?A. Favorable.B. Intolerant.C. Doubtful.D. Indifferent.C“My P.E. teacher taught me maths.”It has been a common joke for years but when a P.E. teacher applied for the head-teacher job, many parents worried that “the joke could come true”. Some parents asked, “Does the P.E. teacher know maths and English?If not, how is he supposed to tutor the students?” But there were still parents who believed P.E. teachers had more time to discipline the students since they didn’t have many classes.This concern is actually a “subject bias”, that is, choosing a P.E. teacher as the head-teacher is not good for the students’ grades since he doesn’t know Chinese, maths, or English. It is acceptable for Chinese teachers, maths teachers and English teachers to be head-teachers because these subjects are important to entrance exams and scores. Such a concern reflects parents’ anxiety in the current educational environment, which tends to link thehead-teacher’s responsible subject with the facts whether the school cares about the class and the children’s performances in the subject.Many people care about their kids’ academic performances only. They don’t care about their kids’ P.E. performance at all. Even if kids have P.E. classes, parents care little. P.E. teachers are in humble position and their classes are often occupied by other teachers. Of course, if students, P.E. performance is related to grades and entrance exams, parents won’t mind “a P.E. teacher being the head-teacher”.At the moment, P.E. is gradually included in entrance exams.In terms of high school entrance examination,Guangzhouwill launch a new high school entrance exam which includes P.E. performance and Health examination in 2021, raising the score to 70 points.In terms of the college entrance examination, universities having the right of independent enrollments added P.E. tests to their entrance exams in 2019. This practice is seen as an important signal that the assessment of physical fitness and athletic ability, which are important aspects of a student’s overall quality, may be included in the college entrance examination in the future.We hope that it’s a trend for P.E. teachers, music teachers and art teachers to become head-teachers.8. By saying “My P.E. teacher taught me maths”, what does the author intend to show us?A. It is just a joke that seldom happened in reality.B. P.E. teachers hardly assist students in maths.C. P.E. teachers are good at teaching maths..D. Parents doubt the ability of P.E. teacher.9. We can infer from paragraph 2 that a P.E. teacher .A. is of little benefit for students’ academic performanceB. is humbler than Chinese, math or English teachersC. reflects whether the school cares about the classD. gets unfairly judged due to the current educational system10. Why doesGuangzhouraise proportion of P.E. performance in high school entrance examination?A. To raise students’ awareness of physical health.B. To call on parents to pay attention to P.E. teachers.C. To test the overall ability of high school students.D. To make P.E. teachers equal with other teachers.11. What opinion does the author hold towards P.E. teachers working as head-teachers?A. Neutral.B. Unexpected.C. Supportive.D. Critical.DBrown cows may not actually make chocolate milk, but pink silkworms（蚕）do produce pink silk, a team of scientists has discovered. To see if they could produce pre-dyed silk-silk that comes color1 ed, straight from the source-the team fed ordinary silkworms mulberry（桑树）leaves that had been sprayed（喷洒）with fabric（织物）dyes（染色剂）. Out of seven tested dyes, only one worked, producing a thread that reminded me of pink-dyed hair.And yes, the worms themselves take on some color1 before they produce silk. Their color1 ful diets did not affect their growth, the team, which included engineers and biologists from the CSIR-National Chemical Laboratory in India, reports in the journalACS Sustainable Chemistry & Engineering. (The researchers didn't look too deeply into how the dyes affected the silkworms' health. After all, silkworms die when people harvest their silk.)The team made dyeing silk this way because color1 ing fabric normally uses large amounts of fresh water. The water gets polluted with dangerous chemicals in the process, requiring costly treatment before factories can send it back into waterways. Dyeing silk directly by feeding silkworms would avoid those water-washing steps. Scientists are just starting to study this idea. However, it remains to be seen if it's commercially successful. In this experiment, the Indian team tested seven dyes, which are cheap and popular in the industry.The scientists found different dyes moved through silkworms' bodies differently. Some never made it into the worms' silk at all. Others color1 ed the worms and their silk but the color1 disappears before the silk is turned into fabric. Only one dye, named "direct acid fast red", showed up in the final, washed silk threads. By the time it made it there, it was a pleasant, light pink.12. The text is most probably a(n) ________.A. science reportB. tourist guideC. animal experimentD. fashion advertisement13. Silkworms can produce pink silk because ________.A. they are born pinkB. they are dyed pinkC. they grow in pink waterD. they are fed dyed food14. Where is the experiment carried out?A. In America.B. In India.C. In Israel.D. In China.15. How many dyes have been proved successful in the experiment?A. One.B. Three.C. Five.D. Seven.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。

Robert probably already came to peace with the thought that he would never see his little friend again until he received a life-changing call. Clearly, a kind stranger reached out to tell him that his beloved cat was safe and sound and couldn’t wait to see him again!The cat went missing years ago, right before Robert was planning on moving from California to Ohio. The sad owner decided to give up his plans and stayed in California for the whole year looking for his missing friend, but in vain. “I remember at one point I was praying and I said, ‘God, I’ll do anything, just bring my Chebon back…’”, Robert said in a video posted on the Ventura County Animal Services. The cat seemed to have disappeared forever and Robert had no other choice than to move on.Then 7 years later, a woman noticed a cat that looked ill, so she decided to catch the animal and take him to the vet (兽医). Luckily, the cat she found had a microchip (微型芯片), and in an instant, they knew who the owner of the 19-year-old cat was. That’s when Rober t received a call saying that his cat was alive.“I was afraid there was some kind of mistake,” Robert said in the reunion video. The man decided to ride on a plane and fly all the way from Los Angeles to see his old friend. After finally seeing the cat, Robert immediately recognized his cat and burst into tears.

Dr. Randall Wright, based in Texas, said the need to watch episode (集) after episode has a similar influence on thebrain to gambling (赌博). What’s more, it often leads to social loneliness, snacking on junk food and a shortage of exercise and sleep, which, over time, is bad for the brain.When you let auto play start the next episode, you can find out what happens next and your brain receives good feedback, Dr. Wright wrote in an article. This right-away satisfaction is similar to gambling where even after a win, you are not satisfied and want to continue playing. With binge-watching, you are not satisfied with stopping after episode five and want to continue watching. This cycle coupled with the snacking and the long time sitting can lead to unhealthy changes in your brain and body over time.Dr. Wright said, “Binge-watching itself is not bad. It becomes problematic when you are watching a third, fourth or fifth episode instead of doing healthy activities.” But he said it is possible to avoid the bad influence of binge-watching with four tips, including staying away from salty, fatty, calorific foods, exercising before a binge-watching, setting an alarm for sleep and balancing TV viewing with socializing.If you add these tips to your binge-watching practice, you can create lasting healthy habits and still enjoy the now-and-then binge-watching time without hurting your brain.29. What might “it” in paragraph 1 refer to?A. Gambling.B. Binge-watching.C. TV series.D. Brain.30. In what way is binge-watching like gambling?A. The long time sitting.B. The changes of feeling.C. The snacking on junk food.D. The immediate satisfaction.31. What is paragraph 3 mainly about?A. The tips on how to develop a healthy lifestyle.B. The reasons why binge-watching is problematic.C. The ways to keep away from binge-watching.D. Do’s and don’ts of binge-watching.32. What may be the best title of the passage?A. Ill Health: The Result of AddictionB. Healthy Habits: A Must of A Better LifeC. Binge-watching: A Killer of Your BrainD. TV-Viewing: Gradual Harm on Your Health第二节（共5小题；每小题2.5分，满分12.5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，选项中有两项为多余选项。
