2021年苏州市景范中学校高三英语月考试卷及答案解析
2021年苏州市景范中学校高三英语月考试卷及答案解析第一部分阅读（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AThe Internet has revolutionized our lives to such an extent (程度) that for most people, the global network has become more than just a tool but rather an important aid in everyday life. More and more people go online as wireless networks have brought the Internet closer and closer: it’s on our mobile phones, in our cars and TV sets, in hospital surgery rooms and in fishing boats that battle the waves of the Atlantic.And this revolution has brought along with it a new way of shopping. Both big and small, e-business websites have flooded the Internet by the hundreds of thousands. Anything you can buy from a brick and mortar store (实体店) you can also buy online: from food and clothes to toys, no matter what you’re looking for, you’re bound to find the right online store with just a few clicks of the mouse. You can use the Internet to find new suppliers, post buying requests or search for products and services.This revolution has affected brick and mortar business owners greatly. And what was their reaction? They’ve opened online stores to go hand in hand with their conventional business.But do the big players have reasons to be afraid? Are we going to start seeing ghostly, deserted Walmarts (沃尔玛) across the country? Probably not in the near future but the day will come when most people will just stop shopping offline anymore. A trip to Walmart wastes time, burns gas.The recent advancements in mobile technology and the introduction of mobile phones with enhanced (提高的) web capabilities have even made some people order their groceries when they get out from work and have them delivered at their doorstep by the time they get home. And as “Time is money”, this practice is lifesaving for people whowork two jobs.Technology will continue to advance and e-business will follow closely in its footsteps. Everything will become easier and less time consuming, leaving us more time to enjoy the things that really matter in life: the ones we love, our friends and hobbies.1. What is Paragraph 1 mainly about?A. The popularity of mobile phones.B. The great influence of the Internet.C. The importance of the Internet.D. The function of the global network.2. In response to the threat of online business, the brick-and-mortar store owners________.A. have stopped their traditional businessB. have started their dislike of the InternetC. have established their own websiteD. have opened their online stores3. What would be the best title for the passage?A. A New Way of Shopping.B. The Internet Revolution.C. What is the Reaction to Online Shopping?D. Is Online Shopping the Future of E-business?BTaking an afternoon nap could keep your brain sharp, a new study has said. Adults ages 60 and older who took afternoon naps showed signs of better mental ability compared to those who didn’t nap, according to a study published in General Psychiatry earlier this week.Researchers analyzed napping habits in 2, 214 older Chinese people and measured their cognitive abilities using several cognitive tests. Participants took the Mini-Mental State Examination and theBeijingversion of the Montreal Cognitive Assessment, both of which test for memory, language and other cognitive abilities. In every category listed in the study, nappers tested statistically higher on average compared to their non-napping counterparts.Researchers did not gather data from people under 60, so a correlation cannot be drawn between napping and younger generations. The study also noted that there are conflicting studies about the benefits and risks of napping.Sleeping behaviors can be affected by a multitude of factors, said Dr. David Neubauer, associate professor atJohnsHopkinsUniversity. “Daily routines, medication use and sleep disorders can all play a role in how frequently someone takes a nap.” he said.Neubauer recommended taking a shorter “power nap” of up to 20 minutes to decrease the chances of transitioning into slow-wave sleep, which makes people feel groggy when they wake up. “Napping can be a healthy part of an older adult’s day”, Neubauer acknowledged, but make sure “sleepiness isn’t due to a treatable nighttime sleep disorder.” Older individuals who want to do all they can to preserve their cognitive functioningshould put nighttime sleep first.4. What is the best way to keep a better cognitive ability for the old?A. Take a nap every day.B. Take sleep disorder seriously.C. Have a good sleep at night.D. Do exercise regularly.5. How did the researchers reach the conclusion?A. By taking the examinations and assessment.B. By analyzing napping habits and giving tests.C. By measuring nappers’ ability and analyzing them.D. By doing an experiment.6. Which has NO effect on one’s sleeping behaviors?A. Taking a nap.B. Medicine treatmentC. Sleep problemsD. Everyday activities.7. What can we know about “slow-wave sleep”?A. It appears in short nap up to 20 minutes.B. People should avoid it in their naps.C. It is a healthy part of an elder’s day.D. It was recommended by Neubauer.CHave you ever been on social media and seen your favorite celebrity talking about a product? These promotions might not be totally random, and are actually seen as a vital part of the marketing process. The question is: How do social media influencers ‘influence’ what you buy?Human desire for status and making friends, combined with our need to belong to a group, makes us receptive to being ‘socially influenced’. Companies often use that desire to have a similar lifestyle to a celebrity we admire to sell or launch a product. So, what do these promotions actually do?Firstly, they can be used to build brand awareness. A social media influencer should have a strong understanding of the platform they operate on, and therefore can create appealing content that not only sticks tothe brand image, but sparks their followers’ interests in a product they might never have seen before.Secondly, influencers can improve a company or product’s relationship with their customer base. According to InMoment’s 2018 US Retail CX Trends Report on customer loyalty, 77% of buyers have been brand loyal for more than ten years. This is also true of 60% of millennials. A popular celebrity can target key customers and talk or blog about a product, which can create an instant and lasting bond with them.Lastly, influencers can improve customer buying habits with seemingly ‘unbiased opinions’. We are more likely to respond to ‘peer recommendation’ than traditional ads, meaning the fact we see an influencer as a ‘friend’ can make us less likely to be doubtful about what we are seeing.So, the next time you see a celebrity talking about a product, you might want to consider that this could be a carefully worked-out marketing strategy designed to target your core needs. If you find yourself examining a product you’ve seen on social media, you may well have been influenced.8. Why do companies invite celebrities to launch products?A. Because celebrities can improve the companies’ public images.B. Because consumers like to share similarity with celebrities.C. Because celebrities want to make more money.D. Because consumers can make friends with celebrities.9. According to the passage, which strategy is often used by influencers?A. Setting up operation platforms.B. Sending gifts to customers.C. Improving relationship with the company.D. Taking advantage of their popularity.10. To customers, the recommendations of influencers seem to be ________.A. offensiveB. subjectiveC. objectiveD. misleading11. The passage is mainly about ________.A. how social media make adsB. how social media influence our lifestyleC. how social influencers affect our buyingD. how celebrities earn fameDThe secrets of dreaming are always interesting psychologists. It is generally acknowledged in the field that dreams people have during this time betweenchildhood and full adulthood, that’s around 30, are the strongest and most influential. Yet not enough is known about the repeated patterns of dreaming. Researchers are still trying to answer a basic question: How does dreaming relate to the life experiences and developmental challenges?G. William Domhoff and Adam Schneider, at theUniversityofCalifornia, help to answer this question by examining the lengthy dream series of two individuals, “Izzy” and “Jasmine”. Izzy provided a collection of 4, 329 dream reports from between the ages of 12 and 25, while Jasmine provided 664 dreams recorded between the ages of 14 and 25.Large collections of dreams like these pose challenges to researchers. Until recently, the means of studying dream series was to employ a team of recorders who take the time to code each dream for a predetermined(预先确定的)number of content categories, and then compare their results. Nowadays, digital technologies enable the analysis of language usage in dreams with high speed, accuracy, and objectivity. This marks a revolutionary advance in the science of dreaming. However,itcan only lead so far.To gain more specific and detailed insights, Domhoff and Schneider tailored word strings(词串)for each dreamer, mixing elements of traditional research with digital tools for analyzing large data sets. For Izzy these word strings included “family and s”, “celebrities” and “fantasy”, while the word strings they created for Jasmine included “familiar places,” electrical equipment” and “music”. The researchers used these word strings to identify connections between their dreams and real lives. Surprisingly, the results of the analysis revealed a great deal of consistency(一致性)and continuity in both sets of dreams. Izzy pays much attention to pop culture, and has affection for famous actors. Jasmine is an accomplished musician and performer.“The frequencies of dream elements show the intensity(强度)of the dreamer’s personal concern with that element in waking thought,” Domhoff and Schneider conclude. For anyone who still claims dreaming is merely random nonsense from the brain and mental world, these findings are hard to explain away.12. What do psychologists agree with about dreams?A. Dreams are influenced by life experiences.B. Dreaming is never nonsense from the brain.C. Dreams in one’s teens and twenties are strongest.D The patterns of dreaming are usually repeated.13. What does “it” underlined in paragraph 3 refer to?A. The collection of dreams.B. Research into dreaming.C. The digital method.D. The challenge for psychologists.14. How do the researchers conduct their study?A. By analyzing large data sets.B. By developing individualized word strings.C. By identifying the patterns of dreaming.D. By making comparison with traditional research.15. Which can be the best title for the text?A. New tech, new findingB. Dreams: reflections of waking realityC. Lives, languages, dreamsD.

It keeps us calm, no matter what the situation is, and it allows us to stay happy during the day. So, here, I would like to share some ways to have a “mind like water”, a state of mind that is as peaceful as calm water. Pick the ones that work for you.◆Listen to your heart Your heart tells you what is the right thing to do. It is where your deepest values （价值观）live. Following what your heart says helps you be true to yourself, and that helps you get a peaceful mind. So learn to listen more to your heart, and do what it tells you to do. ◆ Don't take in too much information Getting more information often means introducing more noise into your mind. That's why not taking in too much information is important for a calm and peaceful mind. You should take in no more information than necessary. ◆ Slow down Whatever you do, you do not need to be in a hurry. Doing so will only take you faster in the wrong direction . First of all, you need to know the right direction to go. Slow down so that you can hear the voice of your heart. Don't think too much about yourself and do something for other people We usually think about our own needs and problems most of the time. But self-centered（自我为中心的）thoughts can't bring peace into our mind. Instead, it may make us feel stressed,. So don't think too much about yourself, forget yourself for a while. Think aboutother people more often and think what you can do for others, then do it. Giving will make you happy and give you peace of mind.4.Which of the following shows the writer's idea? 。
